BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improvement of an unstable and heavy equipment transportation and installation machine such as an operation panel and a switchboard.

[0002]

TECHNICAL BACKGROUND OF THE INVENTION As a means for carrying and installing heavy objects such as an operation panel and a switchboard of this kind, a carrying and installing means using rollers as shown in FIG. 12 and a carrying and installing means by a hand lift shown in FIG. Etc. are common. Since the center of gravity of the operation panel and the switchboard is generally above,
In the former case, it is the easiest to fall while moving and when pulling out the roller, so it is necessary to move while pressing with a lot of human power from four directions in order to prevent falling, or to perform the roller removal operation, There is a problem that not only a lot of manpower is required, but also the work speed is slow. In the latter case of FIG. 13, the trolley is often smaller than the board, and it is very easy to fall. In addition, since the wheels do not have stoppers, the cart may escape when trying to pull out the cart by inclining the board. For this reason, not only is it necessary to place a large number of workers on all four sides, but the fall side cannot be supported by one person, so there is a tendency that it is unavoidable for the fall of the board to protect the human body. is there.

2. Description of the Related Art As a means for solving the above problems, a traveling crane having a cubic frame structure as disclosed in Japanese Utility Model Laid-Open No. 2-103080 has been proposed. Although it is recognized that this traveling crane can stably hold a large-sized or heavy suspended load and can move it in a short time, the traveling crane itself with a cubic frame structure can be adjusted vertically. However, there is still a problem that it takes time to load and unload heavy objects.

SUMMARY OF THE INVENTION An object of the present invention is to provide a transportation and installation machine in which heavy objects such as an operation panel and a distribution board can be efficiently transported and installed efficiently, and the jacks provided at the lower ends of the legs are protected.

The protective rod 21 backs up the jack 18 so that the jack 18 is not completely separated from the leg 1a when the head 18 of the jack 18 and the leg 1a are welded for some reason. It protects against collision and damage.

FIG. 8 shows a metal fitting for connecting the board 12 to the hook 17 for hanging, 23 is a ring, 24 is a shackle, and 25 are screws (not shown) provided at the four corners of the top of the board 12. It is the combined eyebolt. The transportation state of the board 12 using such metal fittings is shown in FIG.

[0011]

[Description of Operation] Next, the operation will be described with reference to the drawings. In the state in which the jack 18 is lowered to the lowest position, that is, the supporting structure 1, the connecting vertical beam 3 and the like are lowered, one or both connecting horizontal beams are connected. 10 is removed, and the board 12 is taken in between both supporting structures 1 while moving the whole manually. After returning the removed connecting cross beam 10 to the old shape, the guide rail 13 is moved and adjusted in this state, and the guide rail 13 is moved.
The support plate 16 attached to the above is moved to position the suspension hook 17 directly above the eyebolt 25 attached to the board 12 in advance. Next, the shackle 24 connecting the ring 23 to the eyebolt 25 is connected, and the ring 23 is connected to the suspension hook 17. Next, all foot levers 18a
Are simultaneously operated to lift both supporting structures 1 by the jack 18 and lift the board 12. The distance between the bottom surface of the board 12 and the floor surface may be about 20 mm. In this state, one worker participates in the leg portion 1a of each support structure 1 and four persons carry the whole to a predetermined installation position. Then, the foot lever 18
The jack 18 is lowered by the operation of a and the board 12 is set at a predetermined installation position. Next, after removing the shackle 24 from the eyebolt 25, the ring 23 is attached to the hanging hook 1.
7 and the eyebolt 25 is removed from the board 12. The work is completed by removing one of the connecting transverse beams 10 from the leg portion 1a and then withdrawing the support structure 1, that is, the entire structure from the board 12. After the work is completed, the bolts 5 and 6 are removed to separate the support structure 1 from the connecting vertical beams 3 and 4. Then, the connection vertical beams and the two supporting structures 1 disassembled are loaded on a truck and brought back.

FIG. 10 shows transportation and installation using the chain block 26, and is an example in which the heavy object 12a is set on the pedestal 27. Further, FIG. 11 shows an example in which a large lighting fixture 29 is fitted and set in a window hole 28 provided in a ceiling in a building or the like. In both examples, the pedestal 27 and the window hole 28 are shown.
The panel 12 and the lighting fixture 29 can be carried in and installed regardless of the presence of the above.

[0013]

As described above, according to the configuration of the present invention,
The following effects can be obtained. (A) Even if a heavy object such as an operation panel or a switchboard has a relatively high center of gravity position, since it is a top suspension means, there is no fall accident unlike the prior art, and transportation is safe, reliable, and quick. Of course, it can be installed, and the supporting structure and both connecting vertical beams can be disassembled, and it is easy to carry in and carry out the transportation installation machine to the site, and of course work efficiency can be improved. (B) Since the connecting vertical beam and the connecting horizontal beam are attachable / detachable to / from the supporting structure, it is possible to easily take in a large heavy object into the supporting structure and improve the loading / unloading efficiency. (C) By equipping the lower end of each leg with a jack with a foot lever, a large heavy object can be restrained and supported by a support structure, and then a slight lifting of the jack allows it to be in a transportable posture, and the installation is also possible. It can be easily done with a slight descending operation. (D) If the head and legs of the jack are disconnected for some reason , the jack is completely separated from the legs by the protective rod that is close to the outer periphery of the jack and is also provided so as to surround it. It is possible to prevent accidents of getting out and to reasonably protect the jack from collision damage to other objects.
