Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a container loading/unloading device for a cargo handling vehicle.

Conventionally, a cargo handling vehicle as shown in Japanese Patent Publication No. 55-13938 has been known.

This cargo handling vehicle has a side frame that is pivotally connected to the chassis at the rear end and is rotatable, and an L-shaped sliding frame that is slidable on the side frame and is rotatable at the rear end position of the side frame. It consists of a member and a jack installed between the chassis and the sliding member.If the jack is extended with the sliding member prevented from sliding, the container will tilt around the pivot at the rear end of the chassis, while the sliding member will tilt. If the jack is extended while allowing the member to slide, after the sliding member slides rearward, only the sliding member rotates about its rear end pivot, and the container is unloaded.

Incidentally, the side frame is subjected to a huge compressive force when the container is tilted, and is constructed as a strength member to withstand this compressive force.

As a result, the overall weight of the equipment increases, resulting in a drawback that a large amount of cargo cannot be accommodated.

The present invention has been made in view of the above points, and it is an object of the present invention to provide a cargo handling vehicle that uses a container as a strength member, eliminates side frames, and reduces weight.

An embodiment of the present invention will be described below with reference to the drawings. An L-shaped frame 2 is provided at the front of a body frame 1 of a cargo handling vehicle, and a container C can be mounted on the body frame 1. It's summery. A rotating shaft 4 fixed to the rear end of the L-shaped frame 2 is slidably fitted into a guide member 3 provided on the inner surface of the vehicle body frame 1. The tip of a lift cylinder 5 serving as a lifting means whose base end is pivotally supported on the vehicle body frame 1 is connected to the center portion of the L-shaped frame 2, and the L-shaped frame 2 is lifted up by the telescoping operation of the lift cylinder 5. can be slid back and forth along the guide member 3. Further, a notch hole 6 is bored in the upper surface of the front end of the guide member 3, and as described later, when the rotary shaft 4 is located below this notch hole 6, the rotary shaft 4 can come out through the notch hole 6. It's getting old.

On the other hand, a locking pin 7 that can be inserted and removed vertically is installed approximately in the center of the guide member 3, and the rotation shaft is connected by the rear end wall 3' of the guide member 3 and the locking pin 7. 4 can be locked and the L-shaped frame 1 can be rotated back and forth.

Next, the lashing means attached to the L-shaped frame 2, the vehicle body frame 1, and the container C and the vehicle body frame 1 will be explained.Brackets 8, 9 are protruded from the front and rear of the lower surface of the container C. A connecting pin 10 that can be fitted into a hole drilled in the L-shaped frame 3 is fitted into the front bracket 8, and a bracket 11 that projects from the rear end of the vehicle body frame 1 is fitted into the rear bracket 9. Connecting pin 1 that can fit into the hole of
2 are fitted. The front bracket 8 may be provided at an appropriate position from the front end of the container C to near the center, that is, at a position corresponding to the L-shaped frame 2.

A guide roller 13 is rotatably supported at the rear end of the vehicle body frame 1, and the container C can move on this guide roller 13. Further, a hook 14 is fixed to the upper end of the L-shaped frame 2, and an engaging pin 15 provided on the front surface of the container C can be engaged with and detached from the hook 14.

Next, to explain the operation of the present invention, in the state shown by the solid line in FIG.
10 and 12 are all removed and then the lift cylinder 5 is extended, the rotating shaft 4 of the L-shaped frame 2 is guided by the guide member 3 and moved rearward. When the rotating shaft 4 comes into contact with the rear end wall 3' of the guide member 3, the extension of the lift cylinder 5 is temporarily stopped. After that, the connecting pin 7 is inserted and the rotating shaft 4 is locked. In the embodiment of the present invention, the rotating shaft 4 is locked by inserting and removing the connecting pin 7, but the mechanism for locking the rotating shaft 4 is not limited to this embodiment. If the connecting pin is made to operate automatically, the lift cylinder 5
It is no longer necessary to pause. When the lift cylinder 5 is further extended from this state, the L-shaped frame 2 is erected around the rotating shaft 4, and the container C can be lowered to the ground while being slid on the guide rollers 13 by its own weight.

Finally, by releasing the hook 14 from the engagement pin 15, the container C can be separated from the L-shaped frame 2.

Moreover, in order to mount the container C unloaded on the ground onto the vehicle body frame 1, the operation in reverse to the above may be performed.

Next, we will explain the case where the container C is dumped while being placed on the L-shaped frame 2. In this case, after inserting the connecting pins 10 and 12, when the lift cylinder 5 is extended, the container C will move the connecting pin 12. It is rotated rearward about the center, and the container C can be dumped as shown in FIG.

Moreover, in order to turn the container C upside down, the above-mentioned operation may be reversed. By the way, at the time of dumping, the front of the container C is connected to the hook 14 at the front end of the L-shaped frame 2 and the engagement pin 15, and the connection pin 10.
The container C is integrated and held together by the connection at , and the rear part of the container C is held by the rigidity of the container C itself.

As described above, according to the present invention, the side frame that was conventionally provided behind the L-shaped frame is no longer necessary.
Accordingly, the weight is reduced and the cost is also reduced.
