Abstract

PURPOSE:To prevent a container frame from being bent when slanted by presing a rising and falling frame by a top end of a lock arm and supporting a rotational power working on the rising and falling frame at a stopper attached to a slanting frame. CONSTITUTION:When unloading a container C of a car body 1 on the ground, a damp cylinder 8 is shortened and a lock arm 7 is rotated anti-clockwise, so that a slanting frame 2 and a L-shaped rising and falling frame 3 are released from a bending preventing state and the slanting frame 2 is fixed on the side of the car body 1. Then, a removable cylinder 6 is extended to rotate the L-shaped rising and falling frame 3 at a rear side and a container C linked via a hook 11 at an upper end of the frmae 3 is unloaded on the ground to be slided on a guide roller 10. The rotatioal power working on the L-shaped rising and falling frame 3 can be supported at a stopper attached on the slanting frame 2. This construction permits to prevent a bending of the container frame F.

Description

[Detailed Description of the Invention] The present invention relates to a container handling vehicle that is capable of loading and unloading containers between the undercarriage and the ground, and is also capable of tilting the containers on the undercarriage. A container is provided with a bendable container frame, a container is mounted on the frame, the container can be lowered to the ground by bending the frame, and the container can be tilted together with the container without bending the frame at all. Cargo handling vehicles are already known.

However, in such conventional container handling vehicles, the container frame bends during the tilting of the container, resulting in impact being applied to the container, and in some cases, there is a risk that the container may fall.

In view of the above, the present invention provides the following: when the container is tilted,
The object of the present invention is to obtain a container cargo handling vehicle whose container frame is not bent.

Hereinafter, the first embodiment of the present invention will be explained with reference to FIGS. 1 to 3. ■ is a container cargo handling vehicle;
A tilting frame 2 is attached to the rear of the container frame 2, and an L-shaped undulating frame 6 is pivoted to the middle part of the tilting frame 2, respectively, and these frames 2, 6 form a container frame. Container 0 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 6 of the L-shaped undulating frame B, and the extension of the detachable cylinder 6 causes the L-shaped undulating frame 6 to move back and forth. It can be rotated.

Incidentally, a dump cylinder 8 is disposed at an intermediate portion between the vehicle chassis 1 and the tilting frame 2 via a lock arm 7, and the container frame F can be tilted by extending 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 11 is a hook fixed to the upper end of the vertical part 6b of the undulating frame 6. A locking pin 12 protruding from the front surface is removable.

Next, to explain the operation according to the first embodiment of the present invention, when unloading the container C on the chassis 1 to the ground, first the dump cylinder 8 is contracted and the lock arm 7 is rotated counterclockwise. The bending prevention state of the tilting frame 2 and the L-shaped undulating frame 6 is released, and the tilting frame 2 is fixed to the vehicle chassis 1 side. Thereafter, when the attachment/detachment cylinder 6 is extended, the L-shaped undulating frame 6 rotates rearward, causing the container O connected via the seven hooks 11 at the upper end of the L-shaped undulating frame 3 to slide on the guide rollers 0. It can be unloaded onto the ground (Figure 6).

Moreover, in order to mount the container 0 unloaded onto the ground onto the vehicle platform 1, the above-mentioned operation may be reversed.

Next, when the container 0 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 part 6 rearward of the pivot 4 of the L-shaped undulating frame 6, and thereby the L-shaped undulating frame 6
The counterclockwise rotational force acting on the container frame F is supported by a stopper 9 fixed to the tilting frame.
refraction can be prevented.

Further, when the container frame is to be returned to the opposite side, the dump cylinder may be contracted.

FIG. 4 shows a second embodiment of the present invention, in which the tip of the lock arm 16 is connected to the pivot 15 of the L-shaped undulating frame 14.
The only difference from the first embodiment is that it can be pressed against the upper surface of the horizontal section 14a in front of the horizontal section 14a, and the rest is 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. This can reliably prevent phenomena such as containers falling.
