Example one

Referring to fig. 1 and 2, a first embodiment of the present application provides a movable carrying device 010 for carrying long-length objects, such as fan blades 030, so as to transport the long-length objects over long distances. Comprises a first bearing part 100, a mounting assembly, a second bearing part 300, a telescopic part 500 and a connecting piece 600.

The mounting assembly includes a mounting member 200 and an adjusting member, the mounting member 200 is hinged to the first bearing portion 100 through a hinge shaft to achieve a movable connection with the first bearing portion 100, the mounting member 200 is used for mounting a blade root 031 of the fan blade 030, and enables the fan blade 030 to move relative to the first bearing portion 100 at least in one direction to achieve an adjustment of the posture of the fan blade 030. The second bearing portion 300 has a bearing surface for bearing the blade body 033 of the fan blade 030. The stretchable part 500 connects the first bearing part 100 and the second bearing part 300, and the first bearing part 100 can be relatively close to or far from the second bearing part 300 by stretching and retracting the stretchable part 500. The connecting member 600 is disposed at an end of the first bearing part 100 away from the second bearing part 300, and is used for receiving a driving force and pulling the first bearing part 100, the mounting member 200, and the second bearing part 300 to move on the ground.

Referring to fig. 3, the adjusting element includes an adjusting element 400, and the adjusting element 400 is used to adjust the posture of the fan blade 030 in one direction. The positioning member 400 is connected to the mounting member 200 and the first bearing portion 100, and the positioning member 400 is used for driving the mounting member 200 to drive the fan blade 030 to move in a direction close to or far away from the second bearing portion 300. The installation component 200 and the positioning component 400 are matched to enable the fan blade 030 to rotate around the hinge shaft on the first bearing part 100 relative to the first bearing part 100 through the installation component 200, so that the included angle between the fan blade 030 and the first bearing part 100 is changed, the first bearing part 100 and the second bearing part 300 are connected through the telescopic part 500, and the whole length of the movable bearing device 010 can be adjusted.

When the fan blade 030 is far away from the second receiving portion 300 (i.e. far away from the ground) by the adjustment of the positioning member 400, the projection of the fan blade 030 on the ground is shortened, and at this time, the distance between the first receiving portion 100 and the second receiving portion 300 is shortened, so that the bearing surface on the second receiving portion 300 is close to the fan blade 030, and the bearing surface can continue to provide support for the fan blade 030. Since the position of the fan blade 030 on the first bearing part 100 can be changed by the positioning member 400, and the distance between the first bearing part 100 and the second bearing part 300 can be adjusted, the overall gravity center position of the movable bearing device 010 can be greatly changed, which leads to easy tipping during the movement of the movable bearing device 010, and therefore, the connecting member 600 is disposed on the first bearing part 350, so that the blade root 031 is close to the connecting member 600 receiving the driving force. Through letting the holistic focus of fan blade 030 be close to the position that portable load-bearing device 010 received drive power, can improve portable load-bearing device 010's stability, in addition through the partial gravity of blade root 031 for the first load-bearing member 350 that receives drive power has relatively great pressure contact in ground, avoids portable load-bearing device 010 to be close to the position of drive power and is pried by fan blade 030 and lift, leads to being difficult to through the friction displacement with ground.

To ensure a stable connection of the mounting member 200 to the fan blade 030, the mounting member 200 includes a flange 210 and a clip 230. The flange 210 has a mounting surface 211 for attaching to the end surface of a blade root 031, and the mounting surface 211 is for attaching to the end surface of the blade root 031. The terminal surface of blade root 031 also the blade root 031 keeps away from the one side of blade body 033, and this terminal surface has many splice bars of level and smooth reference surface and protrusion reference surface, and installation face 211 is in order to guarantee the support of blade root 031, in order to avoid damaging the splice bar again, consequently can set up a plurality of holes of stepping down on ring flange 210 and pass for the splice bar. After the connecting ribs are inserted into the receding holes, the reference surface part of the end surface of the blade root 031 is attached to the mounting surface 211, so that the mounting surface 211 provides good support for the fan blade 030. When fan blade 030 is located portable loading attachment 010, still need carry out position adjustment through setting part 400, consequently the installed part 200 only supports the blade root 031 and can't realize that installed part 200 drives fan blade 030 and move, and clamp 230 sets up and carries out further fixed to fan blade 030 on ring flange 210. The yoke 230 is generally annular, a clamping space is formed in the middle to clamp the outer circumferential surface of the blade root 031, in order to apply a clamping force to the entire outer circumference of the blade root 031 by the yoke 230, the yoke 230 includes a head portion 231 and a tail portion 233, wherein the tail portion 233 can slide relative to the head portion 231 to change the size of the clamping space, and when the clamping space is reduced to a certain position and sufficient clamping force is provided for the outer circumference of the blade root 031, fixing the relative positions of the head portion 231 and the tail portion 233 can fix the yoke 230 and the blade root 031 relatively.

After the fan blade 030 is fixed by the mounting member 200, the fan blade 030 is integrally rotated by the aligning member 400, and since the fan blade 030 has a large weight, the aligning member 400 needs to apply a force large enough to move the fan blade 030. The positioning member 400 uses a hydraulic cylinder, one end of the hydraulic cylinder is connected to the first bearing part 100, the other end of the hydraulic cylinder is connected to the mounting member 200, and the hydraulic cylinder is perpendicular to the hinge shaft of the mounting member 200 and the first bearing part 100, so that the mounting member 200 rotates relative to the first bearing part 100 through the extension and contraction of the hydraulic cylinder, and the mounting member 200 synchronously drives the fan blade 030 to rotate relative to the first bearing part 100. The quantity of pneumatic cylinder can not do the restriction, but generally sets up two pneumatic cylinders in the bilateral symmetry of installed part 200, can guarantee through two hydraulic stems that the atress is balanced so that more smoothly stable when fan blade 030 rotates.

Specifically, one end of the hydraulic cylinder is connected to the first bearing part 100, and the other end is connected to one end of the mounting member 200 away from the hinge shaft. The fan blade 030 is driven to rotate around the hinge shaft by the mounting member 200 through the extension and retraction of the hydraulic cylinder. The fan blade 030 is rotated around an axis perpendicular to the mounting surface 211 by a rotary driving member 700 in the adjusting member, specifically, the rotary driving member 700 includes a base plate 710 and a driving motor 730, wherein the base plate 710 is fixed to the first bearing portion 100, an annular sliding groove is provided on the base plate 710, an annular sliding block 213 is provided on one surface of the flange 210 facing the base plate 710, and the annular sliding block 213 is provided in the annular sliding groove to enable the flange 210 to rotate around an axis perpendicular to the mounting surface 211 relative to the base plate 710. The inner ring of the flange 210 is further provided with gear teeth (not shown), the driving motor 730 is fixed to the chassis 710, and the output end of the driving motor 730 is provided with a gear, and the gear is engaged with the gear teeth so that the gear can drive the flange 210 to rotate when rotating. When the gear is meshed with the gear teeth, the moment arm of the driving motor 730 is the radius of the gear, the moment arm of the flange plate 210 is the radius of the gear teeth, and the radius of the gear teeth is far larger than that of the gear, so that the power requirement of the driving motor 730 can be reduced, and the motor with lower power can drive the fan blade 030 to move integrally. The fan blade 030 rotates around an axis perpendicular to the mounting surface 211, so that the wind resistance of the fan blade 030 when the movable carrying device 010 moves on the ground can be changed, the wind resistance can be reduced, the fan blade 030 can be prevented from being separated from the mounting member 200, and on the other hand, the movable carrying device 010 can be driven by smaller driving force to realize faster transportation speed.

The fan blade 030 can be rotated by the turntable 130 in addition to being rotatable about an axis perpendicular to the mounting surface 211 and being rotatable relative to the first carrier 100 by the hinge of the mounting member 200 to the first carrier 100. Specifically, the adjusting member further includes a rotating table 130, the rotating table 130 is rotatably disposed on the base frame 110 of the first bearing portion 100, and the mounting member 200 is fixedly disposed on the rotating table 130, so that the rotating table 130 can drive the mounting member 200 to rotate when rotating, and the mounting member 200 can drive the fan blade 030 to rotate relatively. Specifically, bed frame 110 includes first section 111 of keeping away from the setting of second load-bearing part 300 and the second section 113 that is close to the setting of second load-bearing part 300, revolving stage 130 rotationally sets up on first section 111, the pneumatic cylinder setting deviates from the one side of second section 113 at installed part 200, and the articulated shaft sets up the one end that is close to second section 113 at installed part 200 again, can drive the articulated shaft synchronous revolution when making revolving stage 130 rotate, be provided with the arc wall in the position that second section 113 is close to first section 111, the both ends setting of articulated shaft makes the articulated shaft can follow the rotation and the motion of installed part 200 in the inner wall of arc wall. The rotary table 130 drives the fan blade 030 to rotate, so that the gravity action line of the fan blade 030 is close to or far away from the second bearing portion 300, when the movable bearing device 010 bears the fan blade 030 to move on the ground and turn, the gravity center position of the fan blade 030 can be adjusted in advance to match with the turning, the gravity center of the fan blade 030 can be relatively close to the turning center when the fan blade 030 turns, and the possibility that the movable bearing device 010 turns over is reduced. On the other hand, the fan blade 030 can also be rotated by the turntable 130 so that the fan blade 030 can avoid obstacles during transportation.

The telescopic part 500 connecting the first load bearing part 100 and the second load bearing part 300 includes a plurality of extension pieces 510. The first carrier part 100 is connected to the extension piece 510 at one end, and the second carrier part 300 is connected to the extension piece 510 at the other end. The extension members 510 are substantially plate-shaped, and have flanges at both sides thereof, and two adjacent extension members 510 are slidably disposed, so that the two adjacent extension members 510 can have an overlapped state and an unfolded state by relative sliding. The overlapped state means that the projections of the two extending members 510 on the ground have a larger overlapped part, and the unfolded state means that the projections of the two extending members 510 on the ground have a smaller overlapped part or even do not overlap. When the two extension pieces 510 are in the unfolded state, the interval between the first bearing part 100 and the second bearing part 300 may be increased, and the substantially plate-shaped extension piece 510 may insulate the fan blade 030 from the ground. By isolating the fan blade 030 from the ground, objects on the ground can be prevented from being carried up, and further the surface of the fan blade 030 can be scratched. When the expansion part 500 is in the expanded state, the expansion part has a longer length, the stress of the second bearing part 300 can form a larger moment, the blade root of the fan blade 030 is arranged at the position close to the driving force, and the first bearing part 100 can be prevented from being pried by goods, so that the pressure between the position close to the driving force and the ground is reduced, and the driving efficiency is influenced. When the two extending members 510 are overlapped, the distance between the first bearing part 100 and the second bearing part 300 can be reduced.

In order to allow the movable carrier 010 to carry the large fan blade 030, the overall length of the telescopic portion 500 and the second carrier 300 may be 30000mm or more in the expanded state of the telescopic portion 500, and 9000mm or less in the overlapped state.

When the movable bearing device 010 is used for bearing a larger fan blade 030, the size of the movable bearing device 010 can be further designed, for example, when the telescopic portion 500 is in the expanded state, the overall length of the telescopic portion 500 and the second bearing portion 300 reaches above 40000mm, and when the telescopic portion 500 is in the overlapped state, the overall length of the telescopic portion 500 and the second bearing portion 300 reaches below 10000 mm.

It should be noted that the size of the movable carrying device 010 can be designed reasonably according to the size of the fan blade 030 to be transported, and is not limited to the above size.

In order to drive the adjacent extension members 510 to be switched between the overlapped state and the unfolded state so as to drive the first carrying part 100 and the second carrying part 300 to move relatively close to or away from each other, the telescopic part 500 further includes a telescopic control member (hidden by a flange, not shown), and the telescopic control member may use a hydraulic cylinder, or may use other structures such as a screw pair. When a lead screw pair is used, a lead screw is connected to one extension piece 510, a lead screw nut is disposed on the other extension piece 510, and the extension piece 510 provided with the lead screw nut is made to approach or separate from the extension piece 510 provided with the lead screw by rotation of the lead screw.

The end of the shaft 033 of the fan blade 030 facing away from the blade root 031 is supported by the second bearing 300 in order to reduce the moment experienced at the mounting 200. However, since the fan blade 030 can rotate about an axis perpendicular to the mounting surface 211, the fan blade 030 can rotate relative to the first bearing portion 100 through the hinge joint of the mounting member 200 and the first bearing portion 100, and can also move relatively closer to or away from the second bearing portion 300 through the rotary table 130, the relative positional relationship between the second bearing portion 300 and the fan blade 030 is dynamic. In order to provide a stable bearing for the end of the airfoil 033 of the fan blade 030 facing away from the blade root 031 in a dynamic environment, the second bearing 300 comprises a mounting platform 310 and a bearing 350. The mounting table 310 is connected to the telescopic part 500 to be relatively close to or far from the first carrying part 100, and a mounting surface 211 is provided on the mounting table 310. The mounting surface 211 is provided with a guide groove extending in a direction toward the first carrying part 100, that is, in a direction parallel to a line connecting the first carrying part 100 and the second carrying part 300. The carrier 350 is slidably engaged with the guide groove such that the carrier 350 can move relatively close to or away from the first carrier portion 100 when sliding along the guide groove. When the position of the fan blade 030 changes relative to the second bearing portion 300, the bearing member 350 slides along the guide groove for a certain distance to match the position change of the fan blade 030, so that the bearing surface on the bearing member 350 can provide stable support for the fan blade 030.

Referring to fig. 3 and 4, when the fan blade 030 needs to be assembled and disassembled, the position of the movable carrying device 010 needs to be fixed, and in order to prevent the movable carrying device 010 from being displaced due to rolling of the wheel body 900, the telescopic part 500 is provided with the telescopic part 800, and the telescopic direction of the telescopic part 800 is perpendicular to the telescopic direction of the telescopic control part, so that the movable end 801 of the telescopic part 800 can be abutted against the ground, thereby preventing the movable carrying device 010 from moving relative to the ground through static friction force between the movable end 801 and the ground, and simultaneously providing an additional supporting point to prevent the movable carrying device 010 from rolling over. A flat plate may be disposed at the movable end 801 of the telescopic member 800 to increase the contact area of the movable end 801 with the ground, so that the movable carrying device 010 has higher stability when being fixed. It should be noted that although the function of the telescopic member 800 is described here as an example of fixing the movable carrying device 010 on the ground, the movable carrying device 010 may be fixed on a square, a dock, or the like, in which case the movable end 801 of the telescopic member 800 contacts a supporting surface of the square, the dock, or the like opposite thereto. In addition, the number of the telescopic pieces 800 can be four, six, and the like, and the increase of the number of the telescopic pieces 800 can avoid the situation that a few telescopic pieces 800 cannot support the ground, which causes difficulty in providing supporting force for the movable bearing device 010.

In order to prevent the telescopic member 800 from tilting the movable carriage 010, the telescopic member 800 needs to be as far away from the ranges of the first carriage 100, the telescopic member 500, and the second carriage 300 as possible to provide a support area as large as possible so that the center of gravity of the movable carriage 010 is located in the support area. Therefore, the expansion member 800 is connected to the expansion part 500 through an expansion member, and the expansion part 500 is provided to an end of the expansion member, by which the expansion part 500 can be relatively distant from the expansion part 500 to expand a support area.

Referring to fig. 5, the movable carrying device 010 inevitably encounters jolt during carrying and transporting of the fan blade 030, the fan blade 030 may be separated from the support of the carrying surface in case of jolt, and even a large moment may be formed to separate from the fixing of the mounting member 200 in case of an excessively large swing amplitude. In order to avoid the blower blade 030 from making a relatively large displacement relative to the second bearing portion 300 due to a jolt, the bearing member 350 includes a frame body 351, a first limiting member 353 and a second limiting member 355. Wherein the frame body 351 is in sliding fit with the guide groove, the first limiting member 353 is fixed on the frame body 351 to form a bearing surface which is substantially parallel to the ground so as to bear the fan blade 030, the second limiting member 355 is arranged on the frame body 351, so that a limiting gap for inserting the blade 033 is formed between the first limiting member 353 and the second limiting member 355, when bumping occurs, the fan blade 030 can be prevented from being separated from a limiting space of the bearing member 350 due to the limitation of the second limiting member 355, and therefore the fan blade 030 is prevented from being separated from the mounting member 200 due to a large moment.

In order to enable the movable bearing device 010 to run on a running road surface with driving force driving, the movable bearing device 010 further includes a wheel body 900. The wheel 900 is disposed on the first bearing portion 100 and the second bearing portion 300, so that the overall center of gravity of the movable bearing device 010 is located between the first bearing portion 100 and the second bearing portion 300, thereby ensuring the overall stability of the movable bearing device 010.

In practical use of such a movable carriage 010: the blade root 031 of the fan blade 030 is hoisted to a position close to the flange 210, and the blade root 031 of the fan blade 030 is fixed through the flange 210 and the hoop 230. The frame 351 of the carrier 350 slides along the guide slot to a suitable position so that the bearing surface of the first stop 353 abuts against the blade 033 of the blower blade 030, and the position of the second stop 355 is adjusted so that the blade 033 of the blower blade 030 is in a stop gap having a suitable size. The movable carrying device 010 is connected to the headstock 050, and the movable carrying device 010 is provided with driving force through the headstock 050 so that the movable carrying device 010 can move on the carrying bottom surface. When the fan blade 030 receives a large wind resistance in the transportation process, the fan blade 030 rotates by controlling the driving motor 730, so that the wind resistance of the fan blade 030 is adjusted, when the fan blade 030 encounters a narrow turning, the first bearing portion 100 and the second bearing portion 300 are relatively close to each other by the telescopic portion 500, the overall size is reduced, in addition, the angle of the fan blade 030 relative to the first bearing portion 100 is adjusted by the adjusting member 400, so that the gravity center of the fan blade 030 is approximately between the first bearing portion 100 and the second bearing portion 300, and the bearing member 350 can also be displaced by the guide groove to maintain the attachment of the fan blade 030 so as to provide a supporting force. When a large and sharp turn is encountered, the position of the gravity action line of the fan blade 030 close to the turning center can be adjusted through the rotary table 130, so that the tipping is avoided. In addition, when the vehicle encounters an obstacle during traveling, the obstacle can be avoided by adjusting the position of the fan blade 030.

It should be noted that the wheel 900 may be replaced with a crawler belt, and the movable carriage 010 may travel on the ground.

The wheel body 900 may be provided only on the first bearing part 100, the extendable part 500, or the second bearing part 300, or any two or three of them. It is sufficient that the first support unit 100, the extendable unit 500, and the second support unit 300 can be supported on the ground as a whole.

It should be noted that the retractable member 800 may also be disposed on the first bearing portion 100 or the second bearing portion 300 to provide support, as long as the movable end 801 can abut against the supporting surface, and the wheel body 900 is separated from the supporting surface to fix the position of the movable bearing device 010.

Through the movable bearing device 010, the fan blade 030 can effectively avoid obstacles in the transportation process, and the fan blade 030 is accepted and dispersed to be prevented from being damaged. The adjustable distance between the first bearing part 100 and the second bearing part 300 may in turn enable the fan blade 030 to pass through various types of curves during transportation.

Example two

Referring to fig. 6, a second embodiment of the present application provides a movable carrying device 010, where the movable carrying device 010 differs from the first embodiment in that:

a support arm 131 extending in a direction away from the ground is provided on the turntable 130, and the middle of the mounting member 200 is hinged to the top of the support arm 131 through a hinge shaft. A through hole is formed at a position of the support arm 131 close to the turntable 130, and the positioning member 400 passes through the through hole and is hinged to a side of the mounting member 200 close to the turntable 130. The end of the positioning member 400 facing away from the mounting member 200 is hinged to the support arm 131. The rotation of the mounting member 200 about the hinge axis at the middle position thereof is controlled by the extension and contraction of the positioning member 400.

EXAMPLE III

Referring to fig. 7 and 8, a first embodiment of the present application provides a transportation cart for carrying fan blades 030 for long-haul transportation. This transport cart comprises a cart head 050 and a movable carrier 010 provided in the first embodiment. The headstock 050 is detachably connected with the connecting piece 600, and the movable bearing device 010 is provided with driving force through the headstock 050, so that the movable bearing device 010 drives the fan blades 030 to move on the ground.

In order to realize that the vehicle head 050 drives the movable carrying device 010 to turn, the vehicle head 050 also needs to be rotatably connected with the movable carrying device 010, so the connecting piece 600 comprises a bearing, the vehicle head 050 is provided with a connecting column perpendicular to the ground, and the connecting column is inserted into the bearing to enable the vehicle head 050 to be rotatably connected with the movable carrying device 010. The connection angle of the vehicle head 050 and the movable bearing device 010 can be changed through the rotatable connection, so that the transport vehicle can turn conveniently.

In order to enable the headstock 050 to effectively receive the movable carrying device 010, the first section 111 and the second section 113 of the base frame 110 are subjected to stepping treatment, namely the first section 111 is far away from the ground compared with the second section 113, so that the part of the headstock 050 can extend into the position below the first section 111, and the connection between the headstock 050 and the movable carrying device 010 is more stable.

In addition, in order to enable the driver or the transport vehicle to know the gravity center condition so as to make adjustment in time, the transport vehicle further comprises a monitoring system, the monitoring system monitors the gravity center position range of the transport vehicle, and guides the adjustment of the posture of the fan blade 030 by obtaining the result of the gravity center position range, or enables the telescopic piece 800 to be telescopic, so that the transport vehicle is prevented from tipping due to too much deviation of the gravity center.

The monitoring system obtains the pressure layout of the transport vehicle by monitoring the tire pressure data of the wheel body, and then obtains the approximate range of the gravity center position through the pressure layout calculation, namely the gravity center position is in the projection range of the transport vehicle on the ground or outside the projection range of the transport vehicle on the ground. In order to make the gravity center position range obtained by the monitoring system accurate and effective, a multipoint arrangement pressure sensor is needed. The monitoring system comprises pressure sensors arranged at least two positions, pressure conditions of different positions are obtained through the pressure sensors arranged at different positions, and then a relatively accurate gravity center position range is calculated, so that the overturning of the transport vehicle can be accurately and effectively prevented by adjusting the posture of the fan blade 030 and stretching the telescopic piece 800 aiming at the gravity center position range.

The transport vehicle further comprises an alarm system matched with the monitoring system, the alarm system is arranged on the vehicle body of the transport vehicle and can set a preset area, when the monitoring system monitors that the gravity center position range is outside the preset area, the transport vehicle is indicated to have a certain rollover risk, and the alarm system sends an alarm to remind a driver of corresponding operation.

The driver cab is arranged in the cab 050 of the transport vehicle, the driver operates the transport vehicle in the cab to operate, the alarm system comprises an alarm piece arranged in the cab, when the driver is in the cab, the monitoring system monitors that the gravity center position range is outside a preset area, the alarm piece in the cab can remind the driver in time, and the driver takes effective measures to avoid the transport vehicle from tipping. The alarm system also comprises an alarm piece arranged outside the cockpit, when the driver is not in the cockpit, and the monitoring system monitors that the gravity center position range is outside the preset area, the alarm piece outside the cockpit can remind the driver in time, and the driver can avoid the transport vehicle from overturning by remote operation or timely entering the cockpit to take effective measures.

The alarm piece can be any one of a sound wave generator, a light generator and a vibrator, or the combination of any two or three of the sound wave generator, the light generator and the vibrator. Specifically, the sound wave generator may be a speaker, or may be a mechanical alarm, as long as it can emit enough sound waves to remind the driver. The light generator can be an alarm lamp, can be a lamp, as long as enough light can be generated to remind the driver. The vibrator can generate vibration, so that a driver feels the vibration to be reminded.

The adjustment of the transport vehicle is actually carried out through the gravity center position range obtained by the monitoring device, and comprises the following conditions:

when the monitoring system monitors that the gravity center position range is separated from or is close to the projection range of the transport vehicle on the ground in the transportation process, the transport vehicle reduces the driving speed, and a driver controls the retractable part to extend out, so that the retractable part 800 can be timely supported on the ground to enlarge the supporting area. The monitoring system monitors that the gravity center position range is in a relatively safe area within the projection range of the transport vehicle on the ground. The driver controls the retraction of the retractable member to avoid collision of the retractable member 800 with obstacles on the driving route.

In addition, in the transportation process, the driver controls the adjusting piece to adjust the posture of the fan blade 030, so that the gravity center position of the transport vehicle is adjusted. For example, when the transport vechicle is about to turn, monitoring system monitors the focus position region earlier, then predetermines a terminal point focus position region through turn direction and radian, and terminal point focus position region is close to the axle center position of turning, and the transport vechicle is turned when the focus of transport vechicle is in terminal point focus position region, can make the transport vechicle focus have less turning radius to reduce centrifugal force, can avoid tumbling. For another example, when the transportation vehicle is about to turn, the monitoring system first monitors the gravity center position area, and if the gravity center position area is relatively high (i.e. far away from the bottom surface), the gravity center of the transportation vehicle and the ground form a large moment arm during turning, and the centrifugal force at the gravity center position of the transportation vehicle forms a large moment to cause the transportation vehicle to have a tendency of tipping. In order to avoid the transport vehicle from tipping over, the control module controls the adjusting piece to lower the gravity center of the fan blade, so that the gravity center is close to the ground.

The transport vehicle can effectively avoid the obstacles in the transport process of the fan blades 030, and accept dispersion to avoid damage to the fan blades 030. The adjustable distance between the first bearing part 100 and the second bearing part 300 may in turn enable the fan blade 030 to pass through various types of curves during transportation.

In addition, other changes may be made by those skilled in the art within the spirit of the present application, and it is understood that such changes are encompassed within the scope of the present disclosure.
