[0001]
BACKGROUND OF THE INVENTION
The present invention belongs to a technical field related to installation of large heavy objects such as ingots and rockets.
[0002]
[Prior art]
In general, large heavy objects are fixedly supported and mounted on a dedicated conveyance platform. A transport platform carrying a large heavy object is lifted and transported by a large transport vehicle. At the installation position of the large heavy object (conveyance platform), the lifting of the conveyance platform by the conveyance vehicle is released and the conveyance platform is lowered and installed.
[0003]
Conventionally, as an installation technique of a large heavy object, for example, the one shown in FIG. 7 is known.
[0004]
In this conventional technology for installing large heavy objects, the girder portion 1a of the gate-shaped conveyance platform 1 on which the large heavy objects P are mounted is lifted by two conveyance vehicles 2 and conveyed. At the installation position, a target 3 made of a frustoconical protrusion serving as a reference for installation of the transport frame 1 is installed. In addition, a positioning means 4 including a truncated cone-shaped groove corresponding to the target 3 is provided on the lower end surface of the leg portion 1 b of the transport frame 1.
[0005]
In this conventional technology for installing a large heavy object, after the axis X of the target 3 and the axis Y of the positioning means 4 are made to coincide with each other by steering capable of fine adjustment of the transport vehicle 2 that has reached the installation position, the transport vehicle The lift of the transport stand 1 by 2 is released and the height of the transport vehicle 2 is lowered, so that the transport stand 1 is lowered and installed. At this time, if there is a deviation S between the axis X of the target 3 and the axis Y of the positioning means 4, the frustoconical taper of the descending positioning means 4 is slid by the frustoconical taper of the target 3. Finally, the frustoconical shape of the positioning means 4 and the frustoconical shape of the target 3 are tightly fitted to ensure the installation accuracy of the transport frame 1. That is, the lowering for installation of the transportation platform 1 and the correction of the position of the transportation platform 2 with respect to the target 3 at the installation position are simultaneously performed.
[0006]
[Problems to be solved by the invention]
In the above-described conventional technology for installing large heavy objects, when the truncated cone taper of the descending positioning means 4 is slid with the truncated cone taper of the target object 3, the target object is loaded with the large heavy object P and the load of the transport platform 1. 3. The positioning means 4 may be damaged, and a close fitting between the truncated cone shape of the positioning means 4 and the truncated cone shape of the target 3 may not be obtained. For this reason, there exists a problem that the high installation precision of the conveyance mount frame 1 cannot be expected. Further, if the strength of the target 3 and the positioning means 4 is increased, the contact surface between the transport gantry and the transport cart is forcibly slid to damage the contact surface. Furthermore, there is a problem that a large heavy object is tilted or shakes due to vibration at that time.
[0007]
The present invention has been made in consideration of such problems, and a method for installing a large heavy load that can highly accurately install a transportation platform carrying a large heavy load at an installation position, and It is an object of the present invention to provide a suitable installation device for a large heavy object that implements the installation method.
[0008]

In order to solve the above-described problems, the following method is employed in the method for installing a large heavy object according to the present invention.
[0009]
That is, as described in claim 1, the transport platform on which a large heavy object is mounted is lifted and transported in a state in which the relative movement with the transport vehicle is restricted, and the lift of the transport platform by the transport vehicle is released at the installation position. When installing the transport platform, the transport platform was lifted in the vicinity of the installation position in the large heavy load installation method that corrects the position of the transport platform relative to at least two targets that are the reference for installation at the installation position. the transfer vehicle is stopped in the state, more guide mechanism provided on at least two positions of the conveying platform, and each interposed between corresponding to the transport platform while measuring the distance and angle to the target transport vehicle conveying platform It is stored in the guide mechanism in advance while sliding the transport frame on the transport vehicle by the slide mechanism that releases the restraint of the transport vehicle and enables relative movement. Les operation and for correcting the position of the transfer platform such that the distance and angles in the normal installation position relative to the target of, by performed the operation for releasing the lifting of the transport frame by the transport vehicle at the same time, the conveying platform of the normal It is characterized by being accurately installed at the installation position.
[0010]
In this means, when releasing the lifting of the transportation platform by the transportation vehicle at the installation position, the operation of correcting the position of the transportation platform by the guide mechanism and the slide mechanism and the operation of releasing the lifting of the transportation platform by the transportation vehicle are linked. Therefore, problems such as breakage of the guide mechanism serving as positioning means and breakage of the contact surface between the transport vehicle and the transport frame do not occur.
[0011]
Furthermore, in order to solve the above-described problems, the large-sized heavy load installation apparatus according to the present invention employs the following means.
[0012]
That is, as described in claim 2, a transport platform on which a large heavy object is mounted, and a transport vehicle that lifts and transports the transport platform in a state in which the transport platform can be lifted and released and the relative movement with the transport platform is restricted. In a heavy-duty heavy equipment installation device provided with at least two targets that are provided at the installation position and serve as a reference for installation of the transportation platform, the restraint between the transportation platform and the transportation vehicle is interposed between the transportation platform and the transportation vehicle. The slide mechanism that enables the relative movement by releasing and the distance and angle at the normal installation position with respect to each target while sliding the transport platform by the slide mechanism while measuring the distance and angle with respect to each target and a guide guiding mechanism stores the distance and angles in the previously normal installation position provided on at least two positions of the conveying platform of such a guide mechanism Operation for correcting the position of the transport platform by Ride mechanism, by performed the operation for releasing the lifting of the transport frame by the transport vehicle at the same time, characterized in that as install accurately conveying platform in the installation position of the normal .
[0013]
In this means, the position of the transport platform relative to the target at the installation position is corrected by sliding the transport platform on the transport vehicle by the slide mechanism and the guide mechanism. At this time, in order to link the operation of correcting the position of the conveyance platform by the guide mechanism and the slide mechanism with the operation of releasing the lifting of the conveyance platform by the conveyance vehicle, the guide mechanism is broken or conveyed in the same manner as described above. There is no problem of damage to the contact surface between the vehicle and the carriage.
[0014]
According to a third aspect of the present invention, in the apparatus for installing a large heavy object according to the second aspect, the slide mechanism is capable of slidably driving the conveyance platform.
[0015]
In this means, the slide mechanism itself has a slide driving force.
[0016]
According to a fourth aspect of the present invention, in the apparatus for installing a large heavy object according to the second or third aspect, the slide mechanism reduces the friction with one of the transport gantry and the transport vehicle by air pressure.
[0017]
With this means, sliding is possible by reducing friction due to air pressure.
[0018]
DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a large-sized heavy load installation method and installation apparatus according to the present invention will be described with reference to FIGS.
[0019]
FIGS. 1-5 shows Embodiment (1) of the installation method and installation apparatus of the large sized heavy article which concern on this invention.
[0020]
This embodiment employs a configuration composed of a large heavy object P, a portal-shaped transport base 1, and two transport vehicles 2 similar to the conventional example described above.
[0021]
The target 3 in this embodiment is a round hole shaft hole dug into the installation surface.
[0022]
Further, in this embodiment, the above-described conventional positioning mechanism 4 is replaced with a guide mechanism 5. The guide mechanism 5 is provided so as to be housed and taken out from the side of the transport frame 1. The guide mechanism 5 is supported by the arm 5 a that can be expanded, contracted and rotated on the transport frame 1, and is fitted to the target 3 supported by the arm 5 a. Shaft 5b. The arm 5a supports the shaft 5b so as to be slidable in the axial direction.
[0023]
Further, in this embodiment, a slide mechanism 6 is added. The slide mechanism 6 is interposed between the transport platform 1 and the transport vehicle 2 and is fixed to the transport vehicle 2 side. The slide mechanism 6 reduces friction with one of the transport platform 1 and the transport vehicle 2 by air pressure, The sliding movement of the carrier base 1 is made possible on the vehicle 2. The slide mechanism 6 is referred to as an air caster or the like, and can reduce the friction with the carrier base 1 at an appropriate portion depending on the air supply mode, and can slide the carrier base 1. Therefore, it is not necessary to separately provide a mechanism for driving the slide, and the structure around the six slide machines is simplified.
[0024]
According to this embodiment, since the guide mechanism 5 and the slide mechanism 6 can be added to the existing device, the existing device can be easily modified.
[0025]
In order to use this embodiment, as shown in FIGS. 1 (A) and 1 (B), the girder portion 1a of the carrier base 1 on which the large heavy object P is mounted is used by two carrier vehicles up to the vicinity of the installation position. Lift and transport.
[0026]
When the transport vehicle 2 reaches the vicinity of the installation position, the transport base 1 is brought close to the normal position by the steering capable of fine adjustment of the transport vehicle 2 with the target 3 as a reference. Thereafter, the transport vehicle 2 is stopped at that position.
[0027]
Subsequently, as shown in FIG. 2 (A), the guide mechanism 5 is taken out from the carrier base 1, the arm 5a of the guide mechanism 5 is extended, and the shaft 5b is fitted to the target 3 to stand. At this time, there is a slight difference in the extension lengths a and b of the arm 5a of the guide mechanism 5. In addition, the lift by the conveyance vehicle 2 of the conveyance mount frame 1 is maintained similarly to the time of conveyance.
[0028]
Subsequently, the slide mechanism 6 is driven. As shown in FIG. 2 (B), the slide mechanism 6 lifts the carrier base 1 with air pressure to reduce friction with the carrier base 1 so that it can slide easily and smoothly. In this state, since the transport frame is supported by the guide mechanism 5, even if the transport frame 1 is slightly tilted or receives a crosswind, it does not slide out relative to the transport vehicle. Thereafter, the guide mechanism 5 is operated, and the transport frame 1 is slid. At this time, as shown in FIG. 5, the guide mechanism 5 stores in advance the extension length c and the angle θ of the arm 5 a of the guide mechanism 5 at the normal position of the transport frame 1. The slide of the conveyance platform 1 is guided so that As a result, a minute difference between the extension lengths a and b of the arm 5a of the guide mechanism 5 is absorbed, and the transport frame 1 moves so as to match the normal position. Although the detailed configuration of the guide mechanism 5 is not particularly described, it is needless to say that the guide mechanism 5 has a configuration necessary for the operation of a guide mechanism such as a control unit that controls driving of a storage unit, an arm, and the like.
[0029]
Subsequently, as shown in FIG. 3A, the lifting of the conveyance platform is released in a state where the guide mechanism 5 and the slide mechanism 6 are operated. At this time, even if a lateral shift occurs in the process of lowering the height of the transport vehicle 2, the transport mount 1 is precisely installed with respect to the normal position by the operation of the guide mechanism 5 and the slide mechanism 6.
[0030]
Subsequently, as shown in FIG. 3C, the height of the transport vehicle 2 is further lowered and the operation of the slide mechanism 6 is stopped. At the same time, the operation of the guide mechanism 5 is also stopped. As a result, the transport stand 1 is precisely installed at a regular position of the installation position.
[0031]
That is, in this embodiment, while lifting the transportation platform 1 on the transportation vehicle 2 to correct the position of the transportation platform 1 relative to the target 3 at the installation position, the lifting of the transportation platform 1 by the transportation vehicle 2 is canceled. Since the transport platform 1 is installed, the target platform 3 and the like are not damaged, and the transport platform 1 loaded with the large heavy object P can be quickly installed at the installation position.
[0032]
FIG. 6 shows an embodiment (2) of the method and apparatus for installing a large heavy object according to the present invention.
[0033]
In this embodiment, the guide mechanism 5 is configured to capture the target 3 by optical means or the like and measure the distance, angle, and the like. When this guide mechanism 5 is used, a slide mechanism 6 that can slide-drive the conveyance platform 1 according to an instruction from the guide mechanism 5 is used.
[0034]
According to this embodiment, since the mechanical connection of the target 3 and the guide mechanism 5 as in the above-described embodiment (1) is avoided, the position of the transport platform 1 can be corrected at high speed. .
[0035]
As described above, in addition to the illustrated embodiment, the present invention can be applied to the transport platform 1 other than the portal shape.
[0036]
Furthermore, the shaft 5b of the guide mechanism 5 and the target 3 can be formed into a frustoconical fitting structure.
[0037]
Furthermore, the guide mechanism 5 can be a mechanical rolling structure such as a roller.
[0038]
【The invention's effect】
As described above , according to the present invention , when a transport platform carrying a large heavy load is lifted by the transport cart and transported to a predetermined position and installed (release is lifted), the transport platform is lifted by the transport vehicle. Since the release (installation) operation is simultaneously performed by the slide mechanism to correct the displacement of the installation position (horizontal position), the transport frame can be accurately installed by a so-called single operation.
[0039]
In addition, the large heavy load installation device according to the present invention can be implemented without impairing the effects of the large heavy load installation method according to the present invention described above. In order to correct the position of the transportation platform relative to the target at the installation position by sliding the transportation platform, the existing device can be easily modified simply by adding a guide mechanism and slide mechanism to the existing device. .
[0040]
Further, according to the third aspect, since the slide mechanism itself has a slide drive force, it is not necessary to provide a separate slide drive mechanism even if the guide mechanism has no drive force, and the structure around the slide mechanism is simplified. There is an effect.
[0041]
Further, as claimed in claim 4, since the transport frame and the transport vehicle are slid relative to each other due to the reduction of the friction due to the air pressure, there is an effect of enabling easy and smooth sliding.
