Description

[Detailed Description of the Invention] This invention relates to a hanging device for a container made exclusively for automobiles and equipped with a cargo handling arm for loading and unloading.

This invention relates to a hoisting device that is equipped with a hoisting device for each container so that it is possible to automatically attach and detach the container by simply manipulating the vehicle and cargo handling arm. It is something.

Conventional containers exclusively for automobiles equipped with loading/unloading arms are not equipped with any hanging equipment, and instead, hanging equipment such as chains is installed on the loading/unloading arm side, and the loading/unloading work is carried out on both sides of the container. Attachment and detachment work had to be done manually using a protruding chain locking section.

The attachment/detachment work must be carried out by the person operating the vehicle and the cargo handling arm from a distance from the control device, or by a person other than the vehicle operator. There was an unavoidable inconvenience.

As mentioned above, this invention is a container that can automate the attachment and detachment of the cargo handling arm and the container without the need for the person operating the vehicle to leave the driver's seat and without the need for any attachment or detachment workers other than the operator. The present invention aims to provide a hanging device.

Before explaining the embodiments of the present invention, the outline of the present invention will be explained.The cargo handling arm mounted on a car is rotated to transfer a container on the ground onto the car, and a container on the car to the ground. In addition to cargo handling operations, mainly loading and unloading,
By engaging the bottom of the rear part of the container with the vicinity of the rear end of the vehicle and operating the cargo handling arm, a damper action can be performed, which is exactly the same as that of a conventional vehicle with a cargo handling arm. In addition to the basic functions described above, the cargo handling arm and the lifting device can be automatically attached and detached by movement of the cargo handling arm.

Its operation is such that the openings of the hooks in the hanging devices provided on both sides of the container face the top edge of the container, while the hanging devices provided on the cargo handling arm side slide over the top edge of the container. Naturally engage the hook opening at the upper edge position.

Once this secured state is completed, the cargo handling arm is raised to lift the container.

In this case, the hanging tool with the hook provided at the upper end is at its lowest position with respect to the container, with the opening of the hook opening at the upper edge of the container, and the hanging tool is placed in the lowermost position when the hook is not engaged with the container. The hanging device itself descends to the lowest position due to its own weight,
A movable range up to a set height position above this position is provided so that the damper action described above can be performed.

In this way, if the container slides over the edge and automatically engages the opening of the hook, and then the cargo handling arm is rotated to lift the container, the container will no longer be tilted forward. When the tensioning device reaches its limit, the container is suspended from its fixed location.

In addition, when dumping a container, the hook of the container hanging device and the hanging device of the cargo handling arm are engaged, and the engagement point between the rear bottom of the container and the rear end of the loading platform acts as a rotation axis. When the cargo handling arm is rotated, the container is tilted as shown in the second figure, and a dumping action is performed.

The condition of the hanging equipment during this dumping action is that the entire load of the container is applied only to the rear side forming the chevron, and the front side is simply connected, and unless it is in an unloaded state, the container will not be able to be dumped. As mentioned above, this invention consists of a hook for hanging the cargo handling arm, and a hanging device connected to the hook to be attached to both sides of the container, and the hanging device is attached to each of the above-mentioned parts. It is designed to be able to exert its effects.

The rear end of the loading platform and the special attachment/detachment mechanism (detailed explanation thereof will be omitted as it is not directly related to the gist of the present invention.

), the ball hitting mechanism on the car 1 side is rotated, and the hanging is performed by moving the hanging tool B connected by the tool A.
The container C, whose rear end is pivoted, is rotated to cause the cargo in the container C to fall. At this time, the ball striking mechanism is rotated to promote the falling phenomenon due to the load shift of the cargo. In order to increase the efficiency more than the effect, it is necessary to allow the container C to independently rotate around the pivot as the load shifts.

Therefore, the hanging point, which is the force point, is the contact point between the hook A and the hanging device B, that is, the distance between the force point of the hook 5 and the front support point II is released, and the load of the container C is moved as the load of the container C is moved.

Although the several embodiments described above differ in structure and operation, they serve the same purpose in achieving the purpose of this invention.

The hanging tool B is used to engage tool A with the hook 5.
It is necessary that the opening 5' of the hook 5 protrudes above the upper edge C' of the container C when there is no load.

This is an integral structure in which two cargo handling arms 2 are connected through a round parr 3 in a gate shape. 3 connects the opening 5' of the hook 5 to the upper edge C' of the container C so that it can slide on the upper edge C' of the container C from its rear and automatically engage the hook 5.
'Protrudes upward and opens at the rear.

In the hanging device B of the container C, when there is no load, the rear member b III rotates counterclockwise in the figure and is movable due to the weight of the entire hanging device B or its configuration according to the configuration of each of the above-mentioned embodiments. When the lower limit of movable position 24 regulated by the range regulating piece 22 is reached and contacted, and the distance between the front support point II and the upper end of the rear member bnI becomes short, the hook 5 tilts forward, and this is the lower limit of the hook 5. It is.

This is because the opening 5' of the hook 5 is on the upper edge C' of the container C and opens toward the rear, so the hanging tool A is on the round par 3 and the hanging ring 4 is on the container C. Natural engagement occurs by sliding movement from the rear to the front of the upper edge C' of C.

The above-mentioned effects mainly refer to the loading and unloading of the container C itself with respect to the vehicle, that is, the relationship between the hanging tool A and the hanging tool B, but the effect on the positional movement of the hook 5 is also In this type of vehicle and container system, a part of the container C and a part of the car 1 are engaged with each other without completely separating the container C from the car 1, and by operating the cargo handling arm 2, The container C is designed to perform a so-called dumping action in which the container C can be turned in half and its contents can be discharged.

In order to achieve this dumping effect, the front member aII of the hanging tool B is configured to exhibit a different effect from the rear member bIII.

When performing a dumping action, a part of the rear part of the container C or a part of the rear part is rotatably engaged with the arm 2 or a part of the body, and the force point of the hook 5 and the container C are rotated.
The distance between the rear support point III in , which acts as a support member when the container C turns half-way, and at this point, the distance between the force point of the hook 5 and the front support point II is the shortest, and the load and load relationship are zero. If the loosening action cannot be performed, the half-turning action of the container C, that is, the dumping action cannot be performed.

As described above, this invention is based on the front support point II and support point III set on the side of the container C, with the hook 5 as the apex.
These objectives can only be achieved by the presence of the relaxing action of the apex and the front support point II, combined with the supporting force between the apex and the rear support point III in the triangle connecting the two.

As mentioned above, when no load is applied to the hook 5 provided in the center of the hanging device B provided on both sides of the container C, the front part is supported based on the weight of the hanging device B itself or the configured mechanism. The members are relaxed, and the hook 5 is tilted forward to the minimum extent that can be expected to perform its hook action, without interfering with the loading and unloading work. When a dark dumping effect is desired, the front member aII of the sling B can be freely engaged by a relaxing action, and the load of the container C can be applied to the entire sling B including the hook 5. In this case, the above-mentioned relaxation effect of the hanging device B is eliminated, and the load can be safely suspended by a balanced load. It is characterized by having the effect of being able to be attached and detached.
