Description

Technical Field

[0001] The utility model relates to the technical field of lifting devices, in particular to a lifting device for loading and unloading containers. Background Art

[0002] A container is a tool for carrying large objects in long-distance transportation. In order to facilitate the stacking of containers, a crane is usually required.

[0003] There are two main types of cranes: one is a large hook-type crane fixed at the port, and the other is a lifting device installed on an engineering vehicle. This type of lifting device mainly uses a hydraulic cylinder to drive the scissor structure to extend and retract, thereby realizing the lifting and lowering of goods. Although the traditional lifting device is stable in extension and retraction, it does not have the function of locking and fixing the container. If the engineering vehicle passes through a bumpy or even inclined road surface, the existing lifting device cannot ensure that the container on it will not fall down.

[0004] Therefore, it is necessary to propose a lifting device for loading and unloading containers to improve the locking and fixing ability of the containers and ensure that the containers will not fall when passing through potholes or even inclined roads. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the existing lifting device has poor locking and fixing ability for containers, which causes the containers to fall when passing through potholes or even inclined roads. A lifting device for loading and unloading containers is now provided.

[0006] The technical solution of the utility model is:

[0007] A lifting device for loading and unloading containers includes a base and a telescopic device, a scissor mechanism is installed on the base, a support platform is fixed on the top of the scissor mechanism, the telescopic device drives the scissor mechanism to extend and retract, a limit frame is provided on the top of the support platform, a fixing groove for fixing the container is provided on the table top of the support platform, the limit frame is fixedly connected to the base, the limit frame is parallel to the table top of the support platform, and a limit groove for fixing the container is provided on the bottom surface of the limit frame, and the fixing groove and the limit frame constitute a storage space for accommodating the container.

[0008] Furthermore, a support rod is provided between the limiting frame and the base, and the support rod fixes the limiting frame and the base.

[0009] Furthermore, the support platform is provided with a guide hole, the top end of the support rod is fixedly connected to the limit frame, and the bottom end of the support rod passes through the guide hole and is then fixedly connected to the base.

[0010] Furthermore, the support rod and the guide hole are slidably connected.

[0011] Furthermore, the support rod is a telescopic structure, and its length can be adjusted by telescoping.

[0012] Furthermore, the support rod is composed of multiple connecting rods nested with each other. Adjacent connecting rods can slide relative to each other. Each connecting rod is provided with through holes, and the through holes on adjacent connecting rods coincide to form fixing holes. After the screw is inserted into the fixing hole, the lengths of the two connecting rods of the fixing hole can be fixed.

[0013] Furthermore, the limiting frame is rectangular.

[0014] Furthermore, an anti-slip pad is provided in the limiting groove, and the anti-slip pad is made of rubber or nylon.

[0015] Furthermore, an anti-slip pad is provided in the fixing groove, and the anti-slip pad is made of rubber or nylon.

[0016] A lifting device for loading and unloading containers according to the present utility model is provided with a limiting frame on the top of a support platform for carrying the container. A fixing groove is opened on the support platform, and a limiting groove is opened on the limiting member. When the container is horizontally moved from the side between the support platform and the limiting frame, the bottom of the container is located in the fixing groove, and the top of the container is located in the limiting groove. When the telescopic device drives the scissor mechanism to rise, the support platform rises close to the limiting frame, realizing the extrusion and fixation of the container by the fixing groove and the limiting groove, effectively avoiding the problem of the container falling. Compared with the traditional technology, this technical solution improves the locking and fixing ability of the container, ensuring that the container will not fall when passing through potholed or even inclined roads.

[0024] In order to make the technical means, technical features, utility model object and technical effects achieved by the present utility model easy to understand, the present utility model will be further described below with reference to specific drawings.

[0025] Embodiment 1:

[0026] As Figure 1 and Figure 2 shown, this embodiment provides a lifting device for loading and unloading containers, including a base 1 and a telescopic device 2. A scissor mechanism 3 is installed on the base 1 with screws 12. A support table 4 is fixed to the top of the scissor mechanism 3 with screws 12. The telescopic device 2 drives the scissor mechanism 3 to expand and contract. A limiting frame 5 is provided on the top of the support table 4. As Figure 3 shown, a fixing groove 6 for fixing the container 13 is formed on the tabletop of the support table 4. The limiting frame 5 is fixedly connected to the base 1 with screws 12. The limiting frame 5 is parallel to the tabletop of the support table 4. A limiting groove 7 for fixing the container 13 is formed on the bottom surface of the limiting frame 5. The fixing groove 6 and the limiting frame 5 form a receiving space for accommodating the container 13. Preferably, both the limiting groove 7 and the fixing groove 6 are rectangular and have the same size as the container 13. Preferably, the telescopic device 2 is a hydraulic telescopic cylinder.

[0027] Preferably, a support rod 8 is provided between the limiting frame 5 and the base 1, and the support rod 8 fixes the limiting frame 5 and the base 1.

[0028] Preferably, as Figure 4 shown, the support table 4 is provided with a guiding hole 9. The top end of the support rod 8 is fixedly connected to the limiting frame 5, and the bottom end of the support rod 8 passes through the guiding hole 9 and is then fixedly connected to the base 1. The support table 4 is slidably connected to the guiding hole 9.

[0029] Preferably, the support rod 8 is a telescopic structure, and the support rod 8 can adjust its own length by telescoping. The support rod 8 is composed of multiple connecting rods 10 nested with each other. Two adjacent connecting rods 10 can slide relative to each other. Each connecting rod 10 is provided with a through hole 11. When the through holes 11 on two adjacent connecting rods 10 coincide, a fixing hole is formed. After the screw 12 is inserted into the fixing hole, the lengths of the two connecting rods 10 at the fixing hole can be fixed. The height of the container 13 may vary, and by adjusting the telescopic length of the support rod 8, the height of the limiting frame 5 can be adjusted accordingly.

[0030] Preferably, the limiting frame 5 is rectangular.

[0031] Preferably, an anti-slip pad is provided in the limiting groove 7, and the anti-slip pad is made of rubber or nylon.

[0032] Preferably, an anti-slip pad is provided in the fixing groove 6, and the anti-slip pad is made of rubber or nylon.

[0033] The anti-slip pads installed in the fixing groove 6 and the limiting groove 7 are both of the same material, and the anti-slip pads therein can play a role in increasing the friction force, achieving the effect of preventing the container 13 from slipping in the fixing groove 6 and the limiting groove 7.

[0034] During operation, as Figure 5 and Figure 6 shown, Figure 6 Figure 16 is a state diagram of the container 13 placed on the lifting device without being locked to the container 13. Figure 5 Figure 18 is a state diagram after the container 13 is locked after being placed on the lifting device. A limiting frame 5 is provided at the top of the support table 4 carrying the container 13. A fixing groove 6 is opened on the support table 4, and a limiting groove 7 is opened on the limiting member. When the container 13 horizontally moves from the side between the support table 4 and the limiting frame 5, the bottom of the container 13 is located in the fixing groove 6, and the top of the container 13 is located in the limiting groove 7. When the telescopic device 2 drives the scissor mechanism 3 to rise, the support table 4 rises close to the limiting frame 5, realizing the extrusion and fixation of the container 13 by the fixing groove 6 and the limiting groove 7, effectively avoiding the problem of the container 13 falling. Compared with the traditional technology, the technical solution improves the locking and fixing ability of the container 13, ensuring that the container 13 will not fall when passing through a pitted or even inclined road surface.

[0035] In summary, the above is only a preferred embodiment of the present invention, and is not used to limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made according to the content of the scope of the patent application of the present invention shall fall within the technical scope of the present invention.
