In the construction process of road and bridge, the steel box girder and the cast-in-place girder become one of the widely adopted structural forms. In the actual construction process, flange plates need to be welded at two ends of the steel box girder. In the prior art, an operation platform is arranged below a flange plate, and the operation platform is used for providing a working space for an operator so as to weld a steel box girder and the flange plate.

But due to the diversity of the specifications of the steel box girders, the specifications of the flange plates to be welded are different. The operation platform in the prior art is only suitable for welding the steel box girder and the flange plate under a certain specification, has a small application range, and simultaneously increases the construction cost due to the need of manufacturing a plurality of operation platforms with different specifications.

In order to solve the technical problem, an embodiment of the utility model provides an operation platform. The operating platform is used for bearing operators who construct workpieces. The workpiece can be a flange plate, a cantilever arm of a steel structure and the like. The following description is given by way of example of a flange plate, and it is to be understood that the following description is intended to be illustrative only and not limiting.

Referring to fig. 1 and 2, the operation platform includes: suspension mechanism 1, carrier mechanism 2 and telescopic coupling mechanism 3. The suspension mechanism 1 and the bearing mechanism 2 are positioned on the same side of the telescopic connecting mechanism 3, and one end part of the suspension mechanism 1 and one end part of the bearing mechanism 2 are respectively and fixedly connected with the side wall of the telescopic connecting mechanism 3. The suspension mechanism 1 is positioned on the bearing surface of the workpiece 4, and the bearing mechanism 2 is positioned below the workpiece 4. The telescopic connection 3 serves to adjust the distance between the suspension means 1 and the support means 2.

Referring to fig. 3, when the workpiece 4 (flange plate) is welded with the steel box girder 100, the upper surface of the workpiece 4 is on the same horizontal plane with the bearing surface of the steel box girder 100, and the upper surface of the workpiece 4 is referred to as the bearing surface. The plane below the workpiece 4 where the steel box girder 100 contacts the position to be welded is called a construction surface, which may be opposite to the carrier 2.

Referring to fig. 1 to 3, the suspension mechanism 1, the carrying mechanism 2 and the telescopic connecting mechanism 3 may be made of a material with high rigidity, such as steel or alloy. Because the material with high rigidity has strong deformation resistance, the material is not easy to deform or crack in the actual application process, and the stability and the safety of the operation platform can be ensured.

Referring to fig. 1 to 3, in the operating platform provided in the embodiment of the present invention, since the suspension mechanism 1 and the carrying mechanism 2 are located on the same side of the telescopic connecting mechanism 3, the operating platform can be suspended on the workpiece 4 at this time. When the operator is on the operation platform, the operator can perform a welding operation on the workpiece 4. And because the suspension mechanism 1 and the bearing mechanism 2 are connected through the telescopic connecting mechanism 3, and the telescopic connecting mechanism 3 can adjust the distance between the suspension mechanism 1 and the bearing mechanism 2, at the moment, an operator can adjust the operating platform according to the height of the workpiece 4 so as to adapt to the workpieces 4 with different heights. Under the combined action of the suspension mechanism 1, the bearing mechanism 2 and the telescopic connecting mechanism 3, the operating platform can adapt to workpieces 4 of various specifications, the application range is expanded, and meanwhile, the construction cost can be reduced.

As a possible implementation, referring to fig. 1, the telescopic connection mechanism 3 may include a first connection frame 30, a second connection frame 31 and a first telescopic member 32. Both ends of the first extensible member 32 are fixedly connected to one end of the first connecting frame 30 and one end of the second connecting frame 31, respectively. The side wall of the first connecting frame 30 is fixedly connected to one end of the support mechanism 2, and the side wall of the second connecting frame 31 is fixedly connected to one end of the suspension mechanism 1. The first telescopic member 32 is used to move the first connecting frame 30 in a direction approaching or departing from the second connecting frame 31. The operation platform further comprises a control member (not shown in fig. 1), which is connected to the first telescopic member 32 and is used for controlling the first telescopic member 32 to move the first connecting frame 30, so that the distance between the suspension mechanism 1 and the carrying mechanism 2 satisfies the first target distance.

In the prior art, a crank truck is also typically used to provide a work platform for the operator. But the crank arm vehicle occupies a large area and cannot work normally under special construction environments (such as oceans, lakes and the like). Therefore, the work of the crank arm vehicle is limited by the size of a construction site and the construction environment, and the application range is small. In the embodiment of the present invention, referring to fig. 1, the carrying mechanism 2 and the suspension mechanism 1 are connected together through the first connecting frame 30, the second connecting frame 31 and the first telescopic member 32, and at this time, the operation platform can be suspended at one end of the workpiece 4 to replace the crank arm vehicle to perform welding operation. Because only need hang operation platform in the one end of work piece 4 can carry out weldment work, operation platform can not receive the size in construction place and the influence of construction environment this moment, has enlarged application range. Further, since the first telescopic member 32 can drive the first connecting frame 30 to move in a direction close to or away from the second connecting frame 31, the distance between the carrying mechanism 2 and the suspension mechanism 1 can be adjusted by the first telescopic member 32, so that the operating platform can adapt to workpieces 4 with different heights, and the application range is further expanded.

Referring to fig. 1, since the control member is connected to the first telescopic member 32, the control member can be used to control the first telescopic member 32 to move the first connecting frame 30, so that the distance between the suspension mechanism 1 and the carrying mechanism 2 satisfies the first target distance. At the moment, an operator only needs to operate the control piece to adjust the operating platform according to the workpieces 4 with different heights, so that the automatic adjustment of the distance between the suspension mechanism 1 and the bearing mechanism 2 is realized, the operation is more convenient and faster, and the working time is saved. The control member may be a control button or switch provided on the controller (not shown in fig. 1), but may of course also be a control button or switch provided on the first telescopic member 32 or the carrier 2 or other structure.

Referring to fig. 1, since the first connecting frame 30 and the second connecting frame 31 are fixedly connected with the carrying mechanism 2 and the hanging mechanism 1, respectively, and a later operation platform is required to be hung at one end of the workpiece 4, an operator performs welding work on the operation platform. Therefore, the first connecting frame 30 and the second connecting frame 31 need to have certain deformation resistance and strength. In the embodiment of the present invention, the first connecting frame 30 and the second connecting frame 31 are made of steel, such as 16a hot rolled section steel, 10a hot rolled section steel or rectangular pipe. The rectangular tube may have a length of 40 cm, a width of 2.5 cm and a height of 40 cm. It should be understood that the materials and specifications of the first and second connection frames 30 and 31 are not limited to the above description. The first connecting frame 30 or the second connecting frame 31 may be formed in a shape of a Chinese character 'ri' or a Chinese character 'tian', which not only further enhances the connecting strength between the first connecting frame 30 and the second connecting frame 31, but also ensures the safety of the operator.

In an alternative, referring to fig. 1 and 2, the first telescoping member 32 may be a telescoping hydraulic cylinder or telescoping rod.

Illustratively, referring to fig. 1 and 2, when the first extension member 32 is a telescopic sleeve cylinder, the piston 320 of the telescopic sleeve cylinder is connected to the first connecting frame 30, and the other end of the telescopic sleeve cylinder is connected to the second connecting frame 31. The other end of the telescopic sleeve hydraulic cylinder is a connection end located at one end of the cylinder body 321 in the telescopic sleeve hydraulic cylinder. When the telescopic cylinder is operated, the piston 320 is extended from the cylinder 321, and the distance between the first link frame 30 and the second link frame 31 is increased. Of course, the first telescopic element 32 may also be a telescopic rod, as long as the adjustment of the distance between the suspension mechanism 1 and the carrying mechanism 2 can be achieved.

In an alternative, referring to fig. 1 to 3, the above-mentioned carrying mechanism 2 may comprise a carrying frame floor 20 and a guard rail 21. One end of the carriage bottom plate 20 is fixedly connected with the telescopic connecting mechanism 3, and two opposite sides of the carriage bottom plate 20 along the length direction of the carriage 2 and one side of the carriage bottom plate 20 far away from the telescopic connecting mechanism 3 are respectively provided with a protective guard 21.

Referring to fig. 1 to 3, the carrying mechanism 2 includes a carrying frame bottom plate 20, and the carrying frame bottom plate 20 is arranged to facilitate the walking and working of an operator on the carrying mechanism 2. The bottom plate 20 may be made of steel with certain bearing capacity, for example, the bottom plate 20 may be a patterned steel plate, the thickness of the patterned steel plate may be 3 mm, and the length and width of the patterned steel plate may be set according to actual conditions. Due to the adoption of the patterned steel plate, the friction force between the operator and the steel plate can be increased, the operator is prevented from slipping, and the construction safety of the operator is ensured. It should be understood that the materials, specifications, and the like of the carrier floor 20 are not limited to those described above.

Referring to fig. 1 to 3, guard rails 21 are respectively disposed on two opposite sides of the carriage base plate 20 along the length direction of the carriage 2 and on a side of the carriage base plate 20 away from the telescopic connection mechanism 3. The protective guard 21 can prevent the operator from falling off the bearing mechanism 2 after the operator walks on the bearing frame bottom plate 20 or falls down during operation, thereby ensuring the construction safety of the operator. The guard rail 21 may be a retractable guard rail, such as a retractable parallelogram guard rail, or a non-retractable guard rail. It should be understood that the shape of the guard rail 21 is various and is not limited to the above description. In the embodiment of the present invention, the guard rail 21 may be made of a rectangular tube, the length of the rectangular tube may be 40 cm, the width of the rectangular tube may be 2.5 cm, and the height of the rectangular tube may be 40 cm. Of course, the material and specification of the guard rail 21 are not limited to the above description.

In an alternative way, referring to fig. 1 to 3, the carriage 2 may further include a first reinforcement member 22, the carriage bottom plate 20 is provided with sliding grooves 23 at two opposite sides along the length direction of the carriage 2, one end portion of the first reinforcement member 22 is slidably connected with the carriage bottom plate 20 through the sliding grooves 23, and the other end portion of the first reinforcement member 22 is hinged with the telescopic connection mechanism 3.

Illustratively, referring to FIGS. 1-3, the axis of the first reinforcement member 22 is at a first predetermined angle A, 0 ≦ A ≦ 90, with respect to the axis of the carrier deck 20. When the first preset included angle a is greater than 0 ° and less than 90 °, the first reinforcement member 22, the carrying mechanism 2 and the telescopic connecting mechanism 3 form a triangular structure. Because the triangular structure has higher stability, the stability of the bearing mechanism 2 and the telescopic connecting mechanism 3 can be ensured at the moment, and further the construction safety of operators is ensured. Since the first telescopic member 32 is provided in the telescopic connecting mechanism 3, the first telescopic member 32 can be used for adjusting the distance between the suspension mechanism 1 and the carrier mechanism 2, so that the position of the first reinforcing member 22 connected with the carrier mechanism 2 needs to be adjusted according to the movement of the first telescopic member 32. Therefore, in the embodiment of the present invention, the bearing bottom plate 20 is provided with the sliding grooves 23 along the two opposite sides of the length direction of the bearing mechanism 2, and one end portion of the first reinforcing member 22 is slidably connected with the bearing bottom plate 20 through the sliding grooves 23. At this time, the first reinforcement member 22 can slide along the length direction of the sliding slot 23 to adjust the size of the first preset included angle. And because another tip of first reinforcement 22 is articulated with telescopic coupling mechanism 3, when the size of first preset contained angle A changes, the angle B between another tip of first reinforcement 22 and telescopic coupling mechanism 3 can change according to the change of first preset contained angle A to guarantee that first reinforcement 22 can normally consolidate bearing mechanism 2 and telescopic coupling mechanism 3. It should be understood that the other end of the first reinforcement member 22 is hinged to the telescopic connecting mechanism 3 by a sliding slot 23 formed in the telescopic connecting mechanism 3 along the length direction of the telescopic connecting mechanism 3, and the other end of the first reinforcement member 22 is hinged to the telescopic connecting mechanism 3 through the sliding slot 23. Of course, other ways of securing the other end of the first reinforcement member 22 in hinged connection with the telescopic connection 3 are also possible.

Referring to fig. 1 to 3, in the embodiment of the present invention, one end of the first reinforcement member 22 is slidably connected to the carrier base plate 20 through the sliding slot 23, and the other end of the first reinforcement member 22 is hinged to the second connecting frame 31 of the telescopic connecting mechanism 3. The triangular structure formed by the first reinforcement member 22, the carrying mechanism 2 and the telescopic connecting mechanism 3 is larger, so that the reinforcement effect of the first reinforcement member 22 can be maximized.

As a possible implementation, referring to fig. 1 to 3, the suspension mechanism 1 described above may comprise a suspension frame base plate 10, a weight member 11 and a second reinforcement member 12. One end of the hanger base plate 10 is connected to the side wall of the telescopic connection mechanism 3. The weight part 11 is connected with one end of the suspension bracket bottom plate 10 far away from the telescopic connecting mechanism 3, and the weight part 11 is used for fixing the position of the suspension bracket bottom plate 10 on the workpiece 4. The two ends of the second reinforcing member 12 are respectively fixedly connected with the side wall of the hanger base plate 10 and the side wall of the telescopic connecting mechanism 3, and the second reinforcing member 12 is used for reinforcing the hanger base plate 10 and the telescopic connecting mechanism 3.

By way of example, with reference to fig. 1 to 3, a second reinforcement 12 is provided between the hanger plate 10 and the telescopic connection 3, in which case the stability of the hanger plate 10 and the telescopic connection 3 can be further ensured on the basis of the connection of the hanger plate 10 to the second connection in the telescopic connection 3. A second preset included angle C is formed between the axis of the second reinforcing member 12 and the axis of the suspension bracket bottom plate 10, and C is more than or equal to 0 degrees and less than or equal to 90 degrees. When the second preset included angle C is greater than 0 ° and less than 90 °, the second reinforcing member 12, the hanger base plate 10, and the telescopic connecting mechanism 3 form a triangle, and the stability of the hanger base plate 10 and the telescopic connecting mechanism 3 can be ensured by using the property that the triangle has stability, so that the construction safety of an operator is ensured. The suspension frame bottom plate 10 may be a steel plate or a patterned steel plate, which is convenient for an operator to walk and work on the suspension mechanism 1.

Referring to fig. 1 to 3, further, a weight 11 is provided at an end of the hanger plate 10 remote from the telescopic connection 3. Even if an operator is positioned at one end of the bearing mechanism 2 close to the telescopic connecting mechanism 3, the suspension bracket bottom plate 10 can still keep balance, so that the suspension bracket bottom plate 10 cannot topple over in the actual use process, and the safety of the operator is further ensured. The weight member 11 may be made of a steel material having a certain weight, such as 16a hot rolled section steel, 10a hot rolled section steel, or rectangular pipe. Of course, other materials may be used, and are not described in detail herein. In the embodiment of the present invention, the weight member 11 has a receiving space, and can be used for placing construction equipment. At the moment, the position of the suspension bracket bottom plate 10 on the workpiece 4 can be fixed, the balance of the suspension bracket bottom plate 10 is ensured, and meanwhile, the suspension bracket bottom plate can also be used for placing construction equipment, so that an operator can conveniently take and place the construction equipment.

Referring to fig. 1 to 3, a climbing ladder 5 is provided at one end of the second link 31 connected to the hanger base plate 10, downwardly along the length direction of the telescopic link 3, by which an operator can rapidly reach the hanger base plate 10 from the loading mechanism 2, thereby accelerating the construction process, through the climbing ladder 5. The climbing ladder 5 is made of a material having high rigidity, such as steel or alloy. Because the material with high rigidity has strong deformation resistance, the climbing ladder is not easy to deform or crack in the practical application process, and the stability and the safety of the climbing ladder 5 can be ensured. The climbing ladder 5 may be a telescopic climbing ladder 5, i.e. the length may be adjusted according to the distance between the hanger base plate 10 and the carrying means 2 for the convenience of the operator. Of course, the climbing ladder 5 may be a common climbing ladder 5, which is convenient for the operator to use. The specification of the above-mentioned climbing ladder 5 will not be described herein.

As a possible implementation, referring to fig. 1 and 2, the operating platform may further include a locking mechanism 6. The locking mechanism 6 is provided on the suspension mechanism 1 for fixing the position of the suspension mechanism 1 on the workpiece 4. And/or a locking mechanism 6 is arranged on the support 2 for fixing the position of the support 2 on the workpiece 4.

Illustratively, referring to fig. 1 and 2, the operation platform may further include a locking mechanism 6, and functions differently according to the position of the locking mechanism 6. For example, the locking mechanism 6 may be disposed on the suspension mechanism 1, and in this case, the locking mechanism 6 may be used to fix the position of the suspension mechanism 1 on the workpiece 4, so as to prevent the suspension mechanism 1 from being displaced relative to the bearing surface of the workpiece 4 during actual use, and ensure the safety of an operator. The locking mechanism 6 can also be arranged on the bearing mechanism 2 and used for fixing the position of the bearing mechanism 2 on the workpiece 4, so that the bearing mechanism 2 is prevented from being displaced relative to the construction surface of the workpiece 4 in the actual use process, and the safety of operators is ensured. Of course, the locking mechanism 6 can be provided at both positions of the suspension means 1 and the carrier means 2 of the operation platform. That is, the locking mechanism 6 may be provided on the suspension mechanism 1 or on the carrier mechanism 2. In this case, the locking mechanism 6 can prevent the suspension mechanism 1 from being displaced with respect to the receiving surface of the workpiece 4, and also prevent the receiving mechanism 2 from being displaced with respect to the working surface of the workpiece 4, thereby further ensuring the safety of the operator.

In an alternative, referring to fig. 1 and 4, the locking mechanism 6 may include a locking nut 60 and a locking bolt 61. The lock nut 60 is fixedly connected to the suspension mechanism 1 in the circumferential direction. In the operating state, a first end of the lock bolt 61 penetrates the lock nut 60, and a second end of the lock bolt 61 abuts against the workpiece 4 to fix the position of the suspension mechanism 1 on the workpiece 4. And/or the locking nut 60 is fixedly connected in the circumferential direction of the support means 2. In the operating state, a first end of the locking bolt 61 penetrates the locking nut 60, and a second end of the locking bolt 61 abuts against the workpiece 4 to fix the position of the carrier mechanism 2 on the workpiece 4.

For example, referring to fig. 1 and 4, when the locking mechanism 6 is disposed on the suspension mechanism 1, the locking nut 60 may be welded to the suspension frame base plate 10 of the suspension mechanism 1 in the circumferential direction. When the operation platform is in an operating state, the first end of the locking bolt 61 penetrates the locking nut 60, and the second end of the locking bolt 61 abuts against the bearing surface of the workpiece 4 by rotating the locking bolt 61, so as to fix the position of the suspension mechanism 1 on the workpiece 4. The locking nut 60 may be welded below the hanger base plate 10, steel plates laid on the hanger base plate 10 are spaced apart from each other, and the locking bolt 61 may move upward or downward relative to the locking nut 60 through a gap between the spaced steel plates. Similarly, when the locking mechanism 6 is disposed on the carrier 2, the locking nut 60 may be welded to the circumference of the carrier 2. When the operation platform is in an operating state, the first end of the locking bolt 61 penetrates through the locking nut 60, and the second end of the locking bolt 61 abuts against the workpiece 4 by rotating the locking bolt 61, so that the position of the bearing mechanism 2 on the workpiece 4 is fixed. Of course, the locking nut 60 can be provided at both positions of the suspension means 1 and the carrier means 2 of the operating platform. That is, the lock nut 60 may be welded to the suspension frame bottom plate 10 of the suspension mechanism 1 in the circumferential direction, or may be welded to the support mechanism 2 in the circumferential direction, in which case the safety of the operator may be further ensured.

In an alternative way, referring to fig. 1 to 4, the locking mechanism 6 may further include a rotation assisting member 7, and the rotation assisting member 7 is fixedly connected to the locking bolt 61 for assisting the rotation of the locking bolt 61.

For example, referring to fig. 1 to 4, the locking mechanism 6 for fixing the position of the suspension mechanism 1 on the workpiece 4 or the locking mechanism 6 for fixing the position of the carrier mechanism 2 on the workpiece 4 may further include a rotation aid 7. Since, in actual use, it is necessary to rotate the lock bolt 61 so that the second end of the lock bolt 61 abuts against the workpiece 4. Be provided with rotatory auxiliary member 7 on locking bolt 61, can increase rotation moment through setting up rotatory auxiliary member 7, and then reduce operating personnel's revolving force, gain laborsaving effect, can also reduce operating personnel's rotation degree of difficulty simultaneously. When the rotation auxiliary member 7 is a linear rotation auxiliary member, the axis of the linear rotation auxiliary member and the axis of the locking bolt 61 may have an included angle D, and the included angle D is greater than 0 degree and less than 180 degrees. In an embodiment of the present invention, the included angle D is 90 °. When the rotation aid 7 is a special-shaped rotation aid, it is sufficient if there is a gap between the special-shaped rotation aid and the locking bolt 61. The profile can be semicircular, oval, or a figure consisting of straight lines and arcs, and the like. The rotation auxiliary member 7 may be made of the same material as the lock bolt 61, but may be made of a different material. The rotating auxiliary part 7 is at a certain distance from the workpiece 4, so that friction between the rotating auxiliary part 7 and the workpiece 4 in the actual use process is prevented, the use effect is prevented from being influenced, and the workpiece 4 is prevented from being damaged.

As a possible implementation manner, referring to fig. 1, 5 and 6, the operation platform may further include an execution unit 8, a driving unit 9 and a control unit. The driving unit 9 is respectively connected with the execution unit 8 and the control unit, and the execution unit 8 is used for driving the suspension mechanism 1 to move on the workpiece 4 under the driving of the driving unit 9. The control unit is used for controlling the driving unit 9 to drive the execution unit 8 to move so as to enable the suspension mechanism 1 to reach the target position.

For example, referring to fig. 1, 5 and 6, the control unit may be configured to control the driving unit 9 to drive the actuator unit 8 to move so as to bring the suspension mechanism 1 to the target position. At this time, the operator can move the suspension mechanism 1 on the workpiece 4 only by using the control unit, and then the operation platform moves on the workpiece 4. Compared with the prior art, the suspension mechanism 1 does not need to be pushed to move by external force when an operator is positioned on the workpiece 4, time and labor are saved, the construction difficulty is reduced, and the construction efficiency is improved. Meanwhile, when the operator uses the control unit, the driving unit 9 and the executing unit 8 to move the operating platform, the operator can observe the relative position between the operating platform and the workpiece 4 in real time, that is, the relative position between the operating platform and the surface to be welded can be observed in real time, so that the operating platform can accurately reach the position to be welded, and the accuracy of movement is improved. In addition, an operator does not need to go back and forth between the suspension mechanism 1 and the bearing mechanism 2, the intermittent working time and the time of the going back and forth are reduced, and the construction efficiency is further improved.

In the embodiment of the present invention, referring to fig. 1, 5 and 6, the execution unit 8 may include four moving wheels, and the moving wheels may move along the width direction of the workpiece 4. Specifically, the moving wheel may be a scaffold brake wheel 80, but may be any other moving wheel suitable for practical use. The above-mentioned drive unit 9 may include a motor 90, a bearing 91, and a conveyor belt 92. The motor 90 is connected with the scaffold brake wheel 80 through a bearing 91 and a transmission belt 92. When the motor 90 is started, the motor 90 can drive the scaffold brake wheel 80 to move. The control unit may be connected to the motor 90 in the driving unit 9, and is configured to control the motor 90 to start or stop, and further control the driving unit 9 to drive the actuator 8 to move, so as to enable the suspension mechanism 1 to reach the target position. The above-mentioned target position refers to the position of the workpiece 4 to be welded. It should be understood that, since the four moving wheels in the execution unit 8 can move along the width direction of the workpiece 4, the execution unit 8 can drive the suspension mechanism 1 to move along the width direction of the workpiece 4 (a flange plate), so as to realize that the operation platform moves to the next position to be welded after welding a welding surface. Further, the control unit may be a control button or a control switch disposed on the controller, and may of course be a control button or a control switch disposed on the suspension mechanism 1 or the carrying mechanism 2 or other structures. Of course, the control unit and the control element can be integrated on one controller, and at the moment, an operator only needs to operate one controller to realize multiple functions, and the integration level is high.

The following describes a specific use manner of the operating platform by taking one possible implementation manner as an example. It is to be understood that the following description is only for purposes of understanding, and is not intended to be limiting.

Referring to fig. 1 to 6, prior to welding, the steel box girder 100 and the flange plate are fixed together using a fixing member (not shown in any of fig. 1 to 6). During actual welding, the moving platform is hoisted to the flange plate through the hoisting device. The operator controls the first telescopic part 32 to adjust the distance between the suspension mechanism 1 and the bearing mechanism 2 according to the height of the flange plate by using a control part in the controller, so that the construction height is met. Next, the operator brings the second end of the lock bolt 61 of the lock mechanism 6 into contact with the flange plate, and fixes the position of the suspension mechanism 1 on the flange plate and the position of the carrier mechanism 2 on the flange plate, respectively. After the mobile platform has been fixed relative to the flange plate, the operator can perform the welding of the flange plate on the suspension tower floor 10 of the suspension means 1 or on the carrier floor 20 of the carrier means 2, respectively.

Referring to fig. 1 to 6, after welding of one flange plate and one steel box girder 100 is completed, an operator moves the moving platform along the length direction of the workpiece 4 to a next position to be welded using a control unit in the controller. After reaching the target position, the operator controls the driving unit 9 to stop working by using the control unit in the controller, and further stops the execution unit 8. At the same time, the operator brings the second end of the locking bolt 61 of the locking mechanism 6 into abutment with the flange plate, and fixes the position of the suspension mechanism 1 on the flange plate and the position of the carrier mechanism 2 on the flange plate, respectively. After the mobile platform has been fixed relative to the flange plate, the operator can perform the welding of the flange plate on the suspension tower floor 10 of the suspension means 1 or on the carrier floor 20 of the carrier means 2, respectively. The above steps are repeated until all the flange plates to be welded and the steel box girder 100 are welded.

In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention.
