Description

Technical Field

[0001] The utility model relates to the technical field of handling equipment, and particularly relates to a combined roller. Background Art

[0002] When loading and unloading heavy goods in a container, due to the large weight of the heavy goods, even reaching 10 tons or more, it is impossible to handle them manually, and a handling device needs to be used for loading and unloading. Also, due to the long length of the container, when it is necessary to handle the heavy goods located at the innermost side in the length direction of the container, the handling device needs to partially or completely enter the container to achieve handling. Moreover, the heavy goods will also occupy a large space inside the container, resulting in the inability to place the handling device in the remaining space of the container. Therefore, it is impossible to use a conventional large forklift for handling.

[0003] For the above problems, in the prior art, it is solved by setting a transportation support platform at the bottom of the heavy goods and jacking and moving the heavy goods, so as to achieve the handling of heavy goods at any position inside the container. Among them, the transportation support platform includes a base, and driving motors are arranged at the four corners of the base. The output ends of the driving motors are sleeved with rollers, so as to achieve the free movement of the transportation support platform.

[0004] However, the rollers installed on the existing transportation support platform are made of all-steel materials, which are easily corroded by the humid marine environment and rust, thus reducing the service life; and they have poor toughness. When colliding with the container or other supporting facilities, they will be deformed and damaged, which is not convenient for actual use. Summary of the Utility Model

[0011] The metal cylinder is sleeved inside the wheel body and is located on the side of the metal ring away from the ring plate.

[0012] By utilizing the material properties of the plastic main body in this application, it can be protected from rust caused by the erosion of the offshore humid environment, thereby extending its service life. It also has high toughness, so when it collides with a container or other supporting facilities, it will be buffered and shock-absorbed, thus avoiding deformation and damage to it, which is beneficial for actual use. Moreover, the stress concentration is reduced by the metal ring, improving the structural strength and enhancing the connection stability. Then, through the internal support of the metal cylinder, the load-bearing capacity, structural stability, and anti-deformation ability are improved, ensuring the use effect.

[0013] Based on the above technical solutions, the solution of this application can be further improved as follows:

[0014] Preferably, the wheel body and the ring plate are integrally formed. By adopting this solution, the conversion and adjustment time during the production process can be reduced, thereby shortening the production cycle.

By adopting this solution, the stress concentration at the connection area between the ring plate and the wheel body can be reduced, thereby improving the structural strength and enhancing the structural stability.

[0016] Preferably, the metal cylinder and the wheel body are connected by riveting or bolting. By adopting this solution, the metal cylinder can be detachably installed inside the wheel body, which is convenient for disassembly and replacement, reducing the maintenance cost.

[0017] Preferably, the outer circumference of the metal ring abuts against the inner circumference of the wheel body. By adopting this solution, the metal ring plays a role in internally supporting the wheel body, improving the structural strength and increasing the load-bearing capacity.

[0018] Preferably, both the first set hole and the second set hole are circular through holes. By adopting this solution, it is adapted to the stud of the bolt, thereby improving the installation tightness and enhancing the connection stability.

[0019] Preferably, multiple first mounting holes are evenly arranged around the first set hole. By adopting this solution, the uniform distribution of stress is ensured, thereby improving the overall load-bearing capacity and enhancing the anti-impact ability.

[0020] Through the above technical solutions, the following beneficial effects are achieved in this utility model:
