Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a container loading/unloading device for a container handling vehicle.

(Prior Art) Generally, there is a undulation frame pivotally supported at the rear end of a vehicle chassis, a refraction frame that is bendably connected to the tip of the undulation frame and has a hook fixed to the upper end, and a space between the vehicle chassis and the refraction frame. In a container cargo handling vehicle equipped with a lift cylinder, if the container is tilted together with the undulating frame and the bending frame while the container is placed on the chassis, if the engagement between the container and the bending frame is insufficient, unexpected damage may occur. The container was falling and it was dangerous.

(Objective) The present invention solves the above-mentioned problem, and aims to connect a hook to be engaged, which is slidably mounted back and forth by a drive means provided in the undulating frame, to an engagement hook fixed to the bottom surface of the container. The purpose is to enable reliable engagement by engaging.

(Embodiment) Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1, 2, and 3. At the rear end of the chassis 1 of the cargo handling vehicle V, a undulation frame 2 is pivotally supported 3 so as to be undulating. An L-shaped refraction frame 4 is connected 5 to the tip of 2 so as to be freely refracted.

On the other hand, a lift cylinder 6 is disposed between the chassis 1 and the bending frame 4, and by the expansion and contraction operation of the lift cylinder 6, the bending frame 4 is bent rearward as will be described later, or the bending frame 4 It is designed to be able to tilt backwards as a unit.

A guide roller 7 is rotatably supported on the same axis as the pivot 3 of the undulating frame 2, and the container C can move on the guide roller 7. A hook 8 is fixed to the upper end of the container C, and an engaging pin 9 provided on the front surface of the container C can be engaged with and detached from the hook 8.

By the way, there is an engaging hook 1 on the bottom of the container C.
0 is fixed thereto, and an engaged hook 11 that can be engaged with the engaging hook 10 is mounted in the undulating frame 2 so as to be slidable back and forth. The engaged hook 11 can be slid back and forth by a cylinder 12 as a driving means arranged between the two. That is, the cylinder 12 is attached to the undulating frame 2 in such a manner that it does not protrude from the top or bottom.

Next, the effects of the present invention will be explained.
As shown in FIG. 1, when tilting the container C with the container C placed on the chassis 1, first
When the lift cylinder 6 is extended after the engaging hook 10 and the engaged hook 11 are contracted and the lift cylinder 6 is extended, the undulating frame 2 and the bending frame 4 are integrated with the container C and are centered around the pivot 3 part. start tilting backwards. Due to this tilting of container C, container C
The contents inside are to be discharged.

Moreover, in order to turn the container C upside down, the above-mentioned procedure may be reversed.

Next, as shown in FIGS. 2 and 3, the chassis 1
To lower the container C to the ground, first slide the engaged hook 11 forward by extending the cylinder 12,
When the engagement hook 10 and the engaged hook 11 are disengaged and the lift cylinder 6 is then extended, the bending frame 4 rotates rearward about the connecting portion 5. Thus, the container C engaged with the upper end of the bending frame 5 can be lowered to the ground.

On the other hand, the container C can be placed on the vehicle platform 1 from the ground by performing the above-mentioned reverse procedure.

As described above, according to the present invention, the container can be easily tilted or loaded or unloaded between the ground by engaging the engaging hook and the engaged hook, and selecting the engaged hook, and also the engaging hook and the engaged hook can be easily engaged. This ensures reliable engagement with the hook and is extremely safe. In particular, if the engagement length of the engagement hook and the sliding length of the engaged hook are made longer, the engagement becomes more reliable.
