[0012]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a light vehicle equipped with a container handling apparatus according to the present invention.

This light vehicle has a container C on its body 1.
It is equipped with container handling equipment for loading and unloading. That is, the container handling device is mounted on the body 1 of a light truck.

The container cargo handling device comprises a cargo handling arm 2 and an undulating cylinder 3 (see the chain double-dashed line) for operating the cargo handling arm 2.

The cargo handling arm 2 has a horizontal portion 21 arranged horizontally when the container C is mounted, and a vertical portion 2 which stands vertically from the tip of the horizontal portion 21 in the same state.
And 2 form an L-shape as a whole.

The rear end of the horizontal portion 21 is rotatably supported by the front end of the dump frame 23 shown by the chain double-dashed line in FIG.
It is rotatably supported at the rear end portion.

The vertical portion 22 is provided at its tip with a hook 24 which can be engaged with and disengaged from an engagement pin C1 provided on the container C.

The hoisting cylinder 3 is connected between the horizontal portion 21 of the cargo handling arm 2 and the vehicle body 1. Specifically, the base end portion 31 of the undulating cylinder 3 is connected to the vehicle body 1 side, and the telescopic rod end 32 is connected to an intermediate portion of the horizontal portion 21.

By the way, the vehicle body 1 side to which the base end portion 31 of the undulating cylinder 3 is connected as described above has the following structure.

2 and 3 show the structure of the vehicle body 1 side.

In the figure, reference numeral 1a designates a vehicle body frame which is disposed in the front-rear direction at a predetermined interval, and a cross member 1b is installed between the front end portions of these vehicle body frames 1a, 1a.

The cross member 1b is composed of the undulating cylinder 3
Is a member for connecting the base end portions 31 of the above, and is firmly fixed to the vehicle body frames 1a, 1a by the fixing means 4 via the connecting frame 1c.

On the body frames 1a, 1a,
Sub-frame 1d from the cross member 1b to the rear,
1d is mounted. The sub-frames 1d and 1d are members for mounting the cargo handling arm 2 and the dump frame 23, and are arranged in the front-rear direction at a narrower interval than the body frames 1a and 1a.

The reason why the distance between the sub-frames 1d and 1d is smaller than the distance between the vehicle body frames 1a and 1a is because the size of the cargo handling arm 2 to be mounted is adjusted. Therefore, by attaching the attachment members 1e, 1e to the outside from appropriate places on the side surfaces of the subframes 1d, 1d and fixing the attachment members 1e, 1e on the vehicle body frames 1a, 1a, the subframes 1d, 1d are attached to the vehicle body. Frame 1
a, 1a is stably placed.

By adopting such a vehicle body structure, it is possible to secure sufficient fastening strength between the vehicle body frame 1a and the cross member 1b, and the undulating cylinder 3 is connected to the cross member 1b. , Undulating cylinder 3
It is possible to stably operate the cargo handling arm 2 and the like accompanying the expansion and contraction of the.

On the other hand, when a cross member for mounting the undulating cylinder is installed between the subframes 1d and 1d, the subframes 1d and 1d and the vehicle frame frames 1a and 1a are arranged.
Even if the sub-frames 1d and 1d are arranged on the vehicle frame frames 1a and 1a via the above-mentioned mounting members or the like due to the positional relationship with the vehicle frame frames 1a and 1a and the cross members, sufficient securing strength is secured. However, there is a problem in that the safety of the operation of the cargo handling arm 2 and the like cannot be ensured.

For example, the container C has an open upper surface as shown in FIG. 1 and a rear wall C2 that is openable and closable around its lower end. A thing that can be opened and closed so that the loaded items can be discharged is used.

The container C is provided with the engaging pin C1 on the upper portion of the front wall thereof, the supporting leg C3 on the front portion of the bottom surface, and the supporting roller C4 on the rear portion of the bottom surface.

Here, the total length of the container C is set to, for example, about 1920 to 1940 mm because it is mounted on a light vehicle, so that when the container C is mounted on the vehicle body 1, the rear end of the container C is By projecting from the rear of the vehicle body 1, the total length of the container C is ensured to be long and the loading capacity is enhanced. The length of the rear end of the container C protruding from the rear of the vehicle body 1 is currently regulated to be within one-tenth of the total length L of the vehicle (light vehicle), and is within this range. Although the total length of the container is set like this, if the legal regulations are relaxed, it may be possible to respond accordingly.

The cargo handling arm 2 for loading and unloading such a container C between the body 1 of a light vehicle and the ground is provided with a horizontal portion 21 having a length L1 of 1 as shown in FIG. The length L2 of the vertical portion 22 is set to be 1 or more with respect to the length L1 of. That is, [the length L1 of the horizontal portion 21 ≦ the length L2 of the vertical portion 22] is set so that the turning locus of the cargo handling arm 2 is largely secured, and the loading and unloading of the container C is performed even in a light vehicle. Is performed smoothly.

Further, a roller 11 for smoothly unloading the container C between the vehicle body 1 and the ground is provided at a rear end portion of the vehicle body 1 (subframe 1d).

Next, the operation of the light vehicle equipped with the container cargo handling device thus constructed will be described.

First, when the container C is unloaded from the vehicle body 1 to the ground, as shown in FIG. 1, with the container C mounted, the hoisting cylinder 3 is extended and the dump frame 23 remains horizontal. By rotating only the cargo handling arm 2 backward, the container C is tilted as shown by the chain double-dashed line in FIG. 1 and is unloaded on the ground as shown by the chain double-dashed line in FIG. Further, the container C on the ground can be loaded on the vehicle body 1 by the operation reverse to the above.

On the other hand, when the container C is dumped on the vehicle body 1 and the cargo in the container C is discharged, as shown in FIG.
After the horizontal portion 21 and the dump frame 23 are integrated by a lashing device (not shown) so as to form a substantially straight line, the undulating cylinder 3 is extended. As a result, the integrated cargo handling arm 2 and the dump frame 23 are pivoted rearward so that the container C is moved to the vehicle body 1 as shown by a chain double-dashed line in FIG.
In the above dumped state, the cargo in the container C can be discharged through the opened rear wall C2 of the container C.

As described above, since the container handling apparatus can be installed in the light vehicle to load and unload the containers C, for example, if a farmer has two containers C, one of the containers C can be unloaded on the ground to collect agricultural products. While the housing is being carried out, the other container C can be mounted on this light vehicle to carry the housed agricultural products and the like. Further, since the equipment can be loaded in the container C, it can be used for transportation and storage of necessary equipment.

Therefore, by making good use of a plurality of containers C, efficient transportation and storage can be performed, and since they are compact, convenient, inexpensive and economical, they are not limited to the above-mentioned farmers, but are small-scaled. It is possible to provide a light vehicle equipped with a container handling device that can be widely used according to needs such as a construction site.
