Abstract

PURPOSE:To temporarily set a container free from a truck without the help of a large-sized fork lift by lifting beams up, which are inserted underneath the container, by means of hydraulic cylinders, and thereby setting the container free from the truck. CONSTITUTION:A stationary stand single body 5a is formed in such a way that a roof 5a2 and a bottom plate 5A3 are fitted onto the upper and lower surfaces of a vertical cylinder body 5A1. In this case, a beam 3 is inserted underneath a container, and the both end sections of the beam are supported by the beam carriers 2A4 nd 2B4 of the bodies 2A and 2B of a lifting device. In addition, a beam 4 is also inserted underneath the container, and the both end sections of the beam are supported by the beam carriers 2C4 and 2D4 of the bodies 2C and 2D of the lifting device. This thereby allows cargoes to be loaded/unloaded with rear and side doors opened as the beams are lifted as they are. Namely, the container is lifted up with these four bodies of the lifting device simultaneously operated by means of both power packages and hydraulic cylinders. Following which, after a truck has been moved, stationary stands are inserted underneath the container, and the lifting device is lowered down, so that the container is thereby fixed onto the stands.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present application relates to a simple container lifting device for lifting and lowering a container, moving it to a fixed platform, and releasing the truck without the need for a large forklift. be.

By using this device, we aim to contribute to the distribution system, which has been expanding more and more in recent years.

[Prior Art] Conventionally, this type of device is as follows.

For example, when transporting JR containers by truck, the current situation is to use a large forklift to load and unload the containers from the truck at the required times.

[Problems to be Solved by the Invention] The conventional techniques described above have the following problems.

In other words, for container truck transportation, 1. A large forklift is essential.

2. Containers cannot be unloaded from trucks at loading/unloading areas without large forklifts, so trucks are left stationary for long periods of time for loading and unloading, causing a deterioration in truck turnover rates.

The present application was made in view of the problems of the prior art, and its purpose is to provide a system that can do the following.

The combination of four movable lifting devices, a beam, and a fixed platform made it possible to temporarily release the container from the truck without the aid of a large forklift.

This made it possible to improve the track rotation rate.

[Means for Solving the Problems] In order to achieve the above object, the present invention is as follows.

In other words, the device of the present application uses a hydraulic cylinder that is raised and lowered by a power package housed in a casing to raise and lower a beam inserted under the container, lift the container, and cut it off from a truck. It is a simple lifting device.

[Effect] The invention works as follows.

1. Insert two beams long enough for the truck to enter and exit between the truck bed and the container.

2. Single lift device 2A on both sides of the beam for the front left and right.
Install B and rear left and right lifting devices 2C and 2D.

3. Operate four hydraulic cylinders simultaneously using a controller to lift the container a certain distance.

4. The container is now separated from the truck.

5. The lifted container is lowered onto a fixed platform by operating a hydraulic cylinder.

In the end, the work involved installing the beam, installing the lifting device, raising the hydraulic cylinder, evacuating the truck, installing the fixed platform, and lowering the hydraulic cylinder.

[Embodiments of the invention] Examples will be described with reference to the drawings.

1 is a simple lifting device for containers according to the present invention.

7 is a known truck, and 8 is a known container.

Reference numeral 2 is a lifting device main body, and front left and right lifting devices are placed on both sides of the truck 7 on the front left and right and rear left and right with a width 7B that allows the truck to enter and exit in parallel to the traveling direction 7A of the truck. It is composed of single units 2A and 2B and rear left and right lifting device units 2C and 2D.

Reference numeral 3 denotes a beam that is removably suspended between the lifting devices 2A and 2B, and 4 is a beam that is removably suspended between the lifting devices 2C and 2D.

Reference numeral 5 denotes a fixed stand, which is composed of front left and right fixed stands 5A and 5B and rear left and right fixed stands 5C and 5D, which are arranged on the front left and right and rear left and right, which are positions directly below the four corners of the known container 8. There is.

6 is an electric control panel, and 6A is an operation box.

Therefore, referring to FIG. 5, the single lifting device 2A 28
2C and 2D will be explained by taking the single lifting device 2A as an example.

A top plate 2A12 and a bottom plate 2A are provided on the upper and lower surfaces of the vertical cylindrical body 2A11.
13, a sliding bearing 2A21 attached to this top plate 2AI2, and a lifting guide 2A4.
1. Consisting of a lot holder 2A23 and a hydraulic cylinder 2A3 disposed at the center of the casing so as to act in the vertical direction, there is a beam receiver at the upper end of the hydraulic cylinder configured to move up and down while being guided by a lift guide rod. 2A4 is provided, and this hydraulic cylinder is configured to be operated by a hydraulic cylinder operating hydraulic package 2A5 disposed within the casing.

2A6 is a transport arm protruding from the left and right side surfaces of the vertical cylindrical body of the casing.

2A7 is a control cable.

Next, the fixed stands 5A, 5B, and 5C.

5D will be explained using a single fixing base 5A as an example.

It is constructed by extending a top plate 5A2 and a bottom plate 5A3 on the upper and lower surfaces of a vertical cylindrical body 5A1.

Therefore, the beam 3 is attached to the bottom surface of the container, and both end portions are the beam receivers 2A4 in the single lifting device 2A, 2B.
．． It will be supported by 2B4.

Also, the beam 4 passes through the bottom surface of the container, and both ends are supported by the beam receivers 2C4 and 2D4 in the lifting devices 2G and 2D, and the rear door or side door can be opened to load and unload cargo. It becomes possible.

FIG. 2 is a perspective view showing the position of the container before operation.

The electric control panel 6 connects the four lifting devices with easily detachable cables in order to provide power and operation instructions to the power package.

An operation box 6 A fJs is pulled out from the electric control panel, and instructions are given by push buttons.

Operation is started by pressing all the push buttons on this operation box.

Through the action of the power package and hydraulic cylinder, the four lifting devices act simultaneously in an upward motion to lift the container.

Further, the four hydraulic cylinders are configured so that they can be raised and lowered independently and their levels can be adjusted by switches in the electric $ control panel 6.

After moving the truck, the fixing platform is inserted under the container, and the lifting device is lowered to secure the container on the fixing platform.

8A in FIG. 3 is the position of the container before operation, and 8B is the position of the container at the end of operation.

After the operation is completed, the truck loaded with containers can be moved with the containers remaining on the lifting device main body 2.

[Effects of the Invention] Since the present invention is configured as described above, it produces the following effects.

1. This device is placed at the customer's site (this allows containers to be loaded onto trucks at all times, and can be loaded onto trucks without the need for a large forklift).

2. By loading this device onto a truck and transporting it to the site, the container can be removed from the truck without the aid of a large forklift, and the truck can engage in other work until the loading is completed.

Therefore, it is possible to improve the track rotation rate.

3. Shippers can handle cargo at a time that is convenient for them.

4. Shippers can use containers as warehouses for the day's products.
