DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet for a pallet truck for improving the efficiency and safety of moving and transporting structures such as switchboards and instruments.

[0002]

2. Description of the Related Art A pallet for a conventional pallet truck has an integral frame formed by closing a vertical plane and a left and right side and forming a fork insertion port at the front and rear portions. It was necessary to prepare many pallets to do. In addition, it was before construction that it was installed at the transfer site along with the structures. Therefore, the conventional work of moving, transporting and installing structures such as switchboards and equipment was carried out by a construction company using rollers and pallet trucks (hereinafter referred to as hand lifters). At present, workability is poor and safety is poor, while taking measures to ensure safety based on the local situation.

[0003]

Therefore, the theme was taken up as to whether there is a means for safely and easily moving a structure and easily transferring the structure to an installation place by effectively utilizing a hand lifter.

[0004]

First of all, apart from the hand lifter, the splitting structure emerged from the viewpoint of the structure of the pallet, because the present situation is the best and there is no room for change. The division allows the degree of freedom of the parallel spacing between the two independent bases to be selected according to the size of the mounting structure, and furthermore, the space between the two parallel bases. It can be understood that the fork can be inserted in the horizontal direction, that is, in the parallel direction, which is different from the conventional case.

[0005] From these facts, a method of solving the problem has been devised by further embodying a horizontal pulling method or a method of raising and lowering the mounted structure. Thus, a pallet for placing and transporting a structure via a pallet truck fork,
The base of the pallet is a divided pallet having two independent longitudinal frame structures, and each of the pallets is provided with a through-frame hole having a width enough to insert a fork. A pedestal with a load capacity of the structure that is pushed up and falls by its own weight is loosely fitted, and a plurality of rollers arranged in parallel in the longitudinal direction slightly protruding from the upper surface of the frame are arranged on the entire area of the frame except the pedestal When transporting, the structure is placed on the pedestal pushed up by the fork, and when transferring the structure, it is separated from the pedestal that has dropped its own weight, transferred to the plurality of rollers, and placed via the rollers. The problem is solved by making it possible to move the structure to the installation place by pulling it laterally from the pallet.

[0006]

According to the structure of the present invention, the base of the pallet is
Each of the separate pallets has a frame structure that is independent of each other and has a through-frame hole that is large enough to insert a fork. A pedestal with a load-bearing structure is loosely fitted and a plurality of rollers arranged in parallel in the longitudinal direction, slightly projecting from the upper surface of the frame, are arranged over the entire area of the frame except for the pedestal. The structure is placed on the pedestal that has been pushed up, and when the structure is relocated, it is separated from the pedestal with its own weight and transferred to the plurality of rollers, and the structure placed on the roller rolls on the roller and pulls sideways Then, it is transferred to the installation site from the divided pallet via another directly connected roller device.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 is an overall perspective view of a split pallet according to one embodiment of the present invention when it is loaded on a hand lifter, FIG. 2 is a plan view of the single unit of the split pallet of FIG. 1, and FIG.
4 is a cross-sectional view, FIG. 4 shows the pedestal in FIG. 1, (a) is a side cross-sectional view, (b) is a plan view, (c) is a plan view of a side wall of a through frame hole in which a boss of the pedestal is loosely engaged, and FIG. 5 is a sectional view of mounting the roller in FIG. 1, FIG. 6A is a front sectional view of the jack stopper in FIG. 1, FIG. 6B is a jack bolt, and FIG. 6C is a plan view.

In FIG. 1, a split type pallet 3 having a frame structure independent of each other, which is significantly different from the conventional pallet in image, is provided with a hand lifter 1 respectively.
The fork 2 is provided with a through-frame hole 20 having a width enough to insert the fork 2 into the through-hole 20, and a pedestal 4 having a structural load-bearing capacity which is pushed up by the up and down operation of the fork 2 and falls by its own weight is loosely fitted. And a plurality of rollers 5 slightly protruding from the upper surface of the frame body and arranged in parallel in the longitudinal direction are arranged over the entire area of the frame body 3 except for the pedestal 4. The structure is placed on the pedestal 4, and when the structure is relocated, the structure is separated from the pedestal having its own weight and is transferred to the plurality of rollers 5 and laterally pulled through the rollers 5 to separate the mounted structure from the divided pallet 3. It can be moved from above to the installation location by another roller or the like.

The pedestal 4 is shown in detail in FIG. 4. The pedestal 4 is inserted into the through frame hole 20 into which the fork 2 of the split pallet 3 is inserted with the open side of the U-shaped cross section facing downward. The fork 2 is pushed up by the raising operation of the fork 2 to receive the structure at a position higher than the level of the roller 5, and is lowered by its own weight by the lowering operation of the fork 2, and has a U-shaped cross section. Objective bosses 8 are provided on both side walls, the bosses 8 are loosely fitted in the oblong holes 9 provided at the target positions of the through-holes 20, and the pedestals 4 are loosely fitted into the through-holes 20 together with the base thereof. When the fork 2 is lowered by its own weight, the structure mounting surface of the pedestal 4 is set to be lower than the level of the roller 5.

In the illustrated embodiment, each pedestal 4 is
Although it is formed with two protruding surfaces, one having a large area may be used, and considering the stability of the mounted object, four is optimal. Non-slip rubber sheets 7 and 12 are attached to the structure mounting surface of the pedestal 4 and the contact surface of the fork. Although not shown in FIG. 3, as shown in detail in FIG. 5, a reinforcing stay 13 is provided for reinforcing the lower frame of the roller 5 of the split pallet 3 having the frame structure.

A jack-type stopper for preventing the mounted object shown in FIGS. 1, 2 and 3 from dropping is shown in detail in FIG. Hole 19 and nut 1 provided in the bottom plate of frame 14
5. A stopper 17 of a flat body, which is pushed up by a bolt 16 via the nut 15 and falls by its own weight and is loosely fitted in the groove frame 14, and a non-slip rubber sheet 18 fixed to the upper surface thereof. .

Further, for safety, eyebolts 21 are provided at both ends of the split pallet 3 to prevent the mounted object from falling off by rope.

[0013]

According to the present invention, as can be seen from the drawings, the separation between the two pallets can be made freely by forming the divided pallets 3 having a long frame structure independent from the conventional pallets and having a significantly different image. By doing so, it is possible to adapt to structures with different widths or lengths, and it is possible to pull it sideways because it has rollers, and the pallet is divided and the space between them is open, so insert the fork of another hand lifter between them The use of hand lifters is expanded because of safety equipment.
