Rear wheel structure of container cargo loader

Abstract

The invention provides a rear wheel structure of a container cargo loader, and belongs to the technical field of container cargo loaders. The technical problems that an existing loader rear wheel is large in occupied space, high in maintenance cost and the like are solved. The rear wheel structure of the container cargo loader comprises a mounting support, a hydraulic oil cylinder is vertically arranged on the upper side of the mounting support, the top end of the hydraulic oil cylinder is fixedly connected with a rack of the container cargo loader, the bottom end of the hydraulic oil cylinder is fixedly connected with the middle of the mounting support, and small tires are arranged at the two ends of the interior of the mounting support. A center shaft penetrates through the middle of the small tire, flange plates are arranged on the two sides of the mounting support, the two ends of the center shaft are fixedly connected with the mounting support through the flange plates, and a maintenance-free bearing is arranged at the position, located in the small tire, of the center shaft in a sleeving mode. The rear wheel structure is small in occupied space, does not need maintenance, and is low in use cost.

Description

technical field [0001] The invention belongs to the technical field of loaders and relates to a rear wheel structure of a container cargo loader. Background technique [0002] The containerized cargo loader is used for short-distance transfer of containerized cargo, such as for airport cargo to get on and off the plane, etc.; in order to adapt to platforms of different heights, it usually has a height-lifting function. Ordinary lifting devices use the principle of leverage. Although the force of the cylinder can be increased when using the principle of leverage to lift the same height, this structure requires a large space and the mechanism is complicated, and the small tires installed are troublesome to disassemble and maintain due to the small space. Contents of the invention [0003] The present invention aims at the above-mentioned problems existing in the prior art, and provides a rear wheel structure of a container cargo loader. The technical problem to be solved by ...
