Description

DETAILED DESCRIPTION OF THE INVENTION A transport vehicle has been developed that has casters and air bearings at the lower end of the intaglio. (Patent application 1987-22779 When the vehicle is empty, it moves on casters, but when it is loaded with a heavy object such as a large power distribution board, the transport vehicle is placed in a floating state along with the heavy object using air bearings.) However, due to the large size of the transport vehicle due to the heavy load involved, it is inconvenient to transport, and if the entrance to the building is too bulky, it cannot be entered.

The present invention allows the transport vehicle to be disassembled into several units to facilitate transportation and to be assembled at the site of use.

Examples will be described with reference to the drawings. Main pipe 1゜2.3,
4. The tail pipe 516, the side pipes 7 and 8, and the eight pipes are each independent units. Although the main pipe II2゜3.4 is not shown, it consists of a large diameter pipe and a small diameter pipe slid into it,
A hydraulic system inside the large-diameter pipe allows its entire length to be expanded and contracted. The tail tube is also made up of large and small diameter tubes and is expandable and retractable using a threaded rod attached inside. Corner fitting 9 is main pipe 1 (2, 3, 4)
A hole is bored into which the ends of the tail pipe 5 (6) can be inserted and locked, and a receiving pipe part 9a3) capable of supporting the side pipe 7 (8) is provided on the side surface. After inserting the tail pipe 5 (6) into the hole of the corner fitting 9,
Weld or secure with bolts, etc. The side pipe 7 (8) can be fixed to the corner fitting 9 with a stopper 9b.

After the eight pipes are delivered to the work site, they are assembled together using four corner fittings 9 as shown in FIG.

After assembly, casters 10 are attached to the lower end of each main pipe.

By extending the two diagonally located main pipes 1 and 3, installation gaps can be created alternately on the lower surfaces of the main pipes 2 and 4. Next, both main pipes 1.3 are shortened and the main pipe 2.4 is extended to similarly create a gap. After the casters have been installed, the transport vehicle transports the heavy object W to a position where it can be lifted. that time,
The position of the lifting fitting of the tail pipe 5 (6) is the lifting fitting of the heavy object W (
(not shown), collect the dowels 9b of the receiving pipe 9a, move the side pipe 7 (8) in and out, and move the tail pipe. Once the lifting position is determined, tighten the stopper 9b again and tighten the side pipe 7 (8)
After fixing, lock the hanging fitting attached to the tail pipe to the heavy object. Next, remove the caster at the bottom end of the main pipe, and
Attach 1. This method is the same as the caster mounting method described above. After all the main pipes are hydraulically extended and the heavy object is lifted to a predetermined height, air is sent to the air bearing to make the transfer vehicle, including the heavy object, in a floating state, and then transferred to the predetermined position.

Since the main pipe that was brought to the work site and laid down is heavy, a jig will be used if necessary to keep it upright.

This jig is a distance block 12 that can be placed on the floor.
and a temporary board 15 pivotally attached to both ends of the board with pins 13.
It consists of The temporary board is provided with a bearing 14 on the other side. The main pipes 1 and 2 that have been carried in are provided with retaining parts 1a and 2a, respectively, so that their lower ends can be pivotally attached to bearings 14 and pins 16. Both should be pivoted together, and a suitable pillow should be placed on the head of the main pipe so that the person lies down.

A wire 17 connects the upper parts of the left and right main pipes 1 and 2, and a ratchet type fastener 18 is provided at the center. After the main pipe is erected by the operation of the fasteners, remove the bottles 13 and 16.

The temporary board 15 is removed when the casters 10 are installed.

As described above, the present invention is characterized in that the transportation vehicle has a simple structure and can be disassembled and assembled, thereby making it lightweight and easy to handle.

Claims (2)

[Claims] (1) Four upright main pipes with built-in hydraulic equipment that can be expanded and contracted, a tail pipe that is removably fixed to the upper end of each pair of main pipes at both ends, and a tail pipe that is removably fixed to the upper end of each main pipe at both ends. An assembly-type transport vehicle for heavy objects, which consists of a side pipe fixed perpendicular to the main pipe, and rollers and air bearings that can be selectively attached to the lower end of each main pipe. (2) A distance block that can be placed on the floor, a temporary board that is removably connected to both ends of the block and equipped with bearings, the lower end of which is pivoted to the bearings of the temporary board, and a pillow is placed on an extension of the block. This main pipe elevation jig consists of a pair of main pipes laid flat, and a wire whose ends can be locked to the upper parts of both main pipes and which can rotate the main pipes into an upright position using attached fasteners.
