Abstract

PURPOSE:To achieve one man control of loading/unloading work by installing a gate frame on the rear body of truck while stretching a beam slidably back and fro in longitudinal direction of body in central position of said frame then mounting a hoist on said beam. CONSTITUTION:Gate frames 3a-3d are installed in front, intermediate and rear positions of the rear body 2 of truck 1 while a pair of bearings are arranged in central position of the upper face of respective gate frame 3a-3d to support the rollers rotatably. Then an upper frame 5 is placed on said rollers 4 while extending back and fro to arrange the lower frame 8 continuously against the upper frame 5 through longitudinal frames 6, 6' standing vertically at the front and rear ends while a beam 9 for hoist is arranged continuously with the longitudinal frames 6, 6' below the lower frame 8. Said beam 9 is supported movably between a roller 11 on a bearing board 10 secured to the gate frame and a roller 13 journaled between the posts 12, 12' secured to the gate to mount the hoist 18 movably along said beam 9.

Description

[Detailed description of the invention] Industrial applications This invention relates to a cargo handling device for a truck.

2. Description of the Related Art Conventionally, as a cargo handling device for a truck, a boom crane is installed at the rear of the driver's seat, and cargo handling operations are performed using the boom crane.

Problems to be Solved by the Invention However, when the boom crane is installed, it is impossible to handle cargo from the rear of the truck bed, and an assistant is required to lift the truck. In some cases, it is impossible to carry out the work, and furthermore, since the boom crane is installed on the loading platform, there are disadvantages such as the usable area of the loading platform becomes narrow.

In order to solve these problems, the present invention provides a structure in which a gate-shaped frame is erected on the truck bed, the gate is constructed so as to be able to slide back and forth, and a hoist is attached to the gate. This system is characterized by the fact that cargo handling can be carried out by one worker from the rear of the loading platform without the need for an assistant, and the loading platform does not become narrow, and can also be used with a canopy.

Means to solve problems Hereinafter, the present invention will be explained in detail with reference to embodiment figures.

A front section formwork 3a, a rear section formwork 3b, intermediate gate formworks 3c, 3d, etc. are erected at the front, rear and intermediate positions of the loading platform 2 of the truck 1, and a pair of formworks are installed at the center position of the upper surface of each gate form. Bearings are attached and the rollers 4 are suspended, and the front and rear gate forms 3 a + 3 b
The upper frame 5, which is longer than the interval length of , is mounted on the upper surface of each roller 4, vertical frames 6 and 6' are suspended from the front and rear ends of the upper frame 5, and each gate is placed at the lower end of the vertical frames 6 and 6'. A lower frame 8 facing the lower surface of the upper reinforcing frame 7 of the formwork is provided in series, and below the lower frame 8, hoist sills 9 are provided in series with the vertical frames 6, 6' to reinforce the upper part of the front section formwork 3a. A bearing plate 10.10' facing both sides of the lower frame 8 is fixed in the center of the frame 7, and a roller 11 that comes into contact with the lower surface of the lower frame 8 is suspended at the lower end of the bearing plate 10.10'. Similarly, a pair of support columns 12.12' are attached to the upper reinforcing frame 7 of the front section formwork 3a, and both ends of the shaft 14 on which the roller 13 that comes into contact with the lower surface of the hoist frame 9 is suspended are attached to the support columns 12.12'. A bearing plate 1 is installed at the center of the upper reinforcing frame 7 of the rear section formwork 3b and faces both sides of the lower frame 8.
0. 10' is fixed, and a roller 11' that comes into contact with the lower surface of the lower frame 8 is suspended at the lower end of the bearing plates 10, 10'. .15' is provided protrudingly, and an L-shaped automatic locking piece 16.16' is pivotally attached to the upper end of the C-shaped receiver 15.15', and the lower surface of the rear end of the lower frame 8 and the lower surface of the lower frame 8 are located closer to the front. A stopper shaft 17.17' that fits into the C-shaped receiver 15.15' is attached to the stopper shaft 17.17' to protrude laterally, so that the hoist 18 can be mounted on the hoist slot 9. Note that 19 and 19' in the figure indicate frames.

Functions and Effects When the cargo handling device according to the present invention is installed on the loading platform 2 of the truck 1, a hood frame 19 is provided above each gate frame 3 and protrudes above the driver's seat from the front section frame 3a. A protective frame 19' for the upper and lower frames and a hoist girder is provided, and the outer peripheral surface of each gate frame is integrally covered with a hood.

When the truck 1 is running, the upper and lower frames 5 and 8
At the same time, the hoist girder 9 is guided forward, and the stopper shaft 17 that protrudes laterally from the rear end of the lower frame 8 is attached to the C-shaped receiver 1.
5 and is locked with an automatic locking piece 16. When carrying out cargo handling work at a desired location, the automatic locking piece 16 of the stopper shaft 17 is rotated upward to lock the stopper shaft 17. After releasing the locking, the upper and lower frames 5, 8 and the hoist bracket 9 are guided rearward and pulled out, and the front stopper shaft 17' is fitted into the C-shaped receiver 15' to lock automatically. The hoist 18 connected to the battery of the truck 1 is moved to the rear position of the hoist holder 9, and the worker hooks the cargo to the hook of the hoist 18 by operating a switch. After hoisting the cargo to an appropriate height, the hoist 18 is moved to a predetermined position on the platform 2, and the hook is lowered by operating a switch to land the cargo on the platform 2. Conversely, the cargo on the upper surface of the loading platform 2 is lifted up by the hoist 18, moved rearward, and landed on the ground behind the loading platform 2. Therefore, the cargo handling device according to the present invention lifts up the cargo on the upper surface of the loading platform 2 of the truck 1, moves it rearward, and lands it on the ground behind the loading platform 2.
By mounting a hoist 9 on the ceiling of the gate frame 3 so that it can be guided forward and backward, it is easy for workers to load cargo from the rear of the truck or unload cargo from the rear of the truck. As mentioned above, it is possible to easily install the loading platform 2 even if it has a canopy or a box structure, and the usable area of the loading platform 2 is not narrowed and the equipment cost is low. It has many remarkable effects.
