Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a container handling vehicle capable of loading and unloading containers between the undercarriage and the ground, and also capable of tilting the containers on the undercarriage.

Conventionally, a bendable container frame is provided on the undercarriage, and the container is mounted on this frame.
Container cargo handling vehicles are already known which are capable of unloading a container onto the ground by bending the frame, and which are also capable of tilting together with the container without bending the frame.

However, with conventional container handling vehicles,
During the tilting of the container, the container frame bent, resulting in impact being applied to the container, and in some cases, there was a risk that the container would fall.

In view of this, an object of the present invention is to provide a container cargo handling vehicle in which the container frame is not bent when the container is tilted.

Below, a first embodiment of the present invention will be described with reference to FIGS. A letter-shaped undulating frame 3 is supported by pivots 4 and 5, respectively, and these frames 2 and 3 constitute a container frame F,
A container C can be mounted on this container frame F.

On the other hand, a detachable cylinder 6 is disposed between the front end of the tilting frame 2 and the middle of the horizontal part 3a of the L-shaped undulating frame 3, and the L-shaped undulating frame 3 is rotated back and forth by the extension of the detachable cylinder 6. can be moved.

By the way, a lock arm 7 is rotatably supported in the middle part of the tilting frame 2, and a dump cylinder 8 is disposed between the lock arm 7 and the chassis 1.
is provided, and the container frame F can be tilted by the extension operation of the dump cylinder 8.

In addition, 9 is a stopper fixed to the lower surface of the front end of the tilting frame 2. The horizontal part 3a of the L-shaped undulating frame 3 is placed on this stopper 9, and 10 is a stopper that is coaxial with the pivot shaft 5 of the tilting frame 2. The container C can move on the guide roller 10, and the hook 11 is fixed to the upper end of the vertical part 3b of the undulating frame 3. Locking pin 1 protruding from the front
2 is removable.

Next, to explain the operation according to the first embodiment of the present invention, when the container C on the chassis 1 is lowered to the ground, the dump cylinder 8 is first contracted and the lock arm 7 is rotated counterclockwise. Therefore, the bending prevention state of the tilting frame 2 and the L-shaped undulating frame 3 is released, and the tilting frame 2 is also fixed to the chassis 1 side. Thereafter, when the attachment/detachment cylinder 6 is extended, the L-shaped hoisting frame 3 rotates backward, and the container C, which is connected via the hook 11 at the upper end of the L-shaped hoisting frame 3, is slid on the guide rollers 10 and placed on the ground. (Figure 3).

Moreover, in order to mount the container C unloaded on the ground onto the vehicle platform 1, the above-mentioned operation may be reversed.

Next, if the container C is to be tilted while being placed on the container frame F, the dump cylinder 8 may be extended (FIG. 2). By the way, the tip of the lock arm 7 presses the lower surface of the horizontal portion 3a rearward of the pivot 4 of the L-shaped undulating frame 3, and as a result, the counterclockwise rotational force acting on the L-shaped undulating frame 3 causes the tilting. It is supported by a stopper 9 fixed to the frame, and as a result, bending of the container frame F can be prevented.

Moreover, when the container frame F is to be laid down, the dump cylinder may be contracted.

FIG. 4 shows a second embodiment of the present invention, in which the tip of the lock arm 13 can be pressed against the upper surface of the horizontal portion 14a in front of the pivot 15 of the L-shaped undulating frame 14. This embodiment differs from the first embodiment only in this point, and is otherwise the same as the first embodiment.

As described above, according to the present invention, it is possible to reliably load/unload or tilt the container, and also to reliably prevent the container frame from bending during the tilting of the container. In other words, it is possible to reliably prevent the phenomenon that occurs when a container falls.
