Background
The lifting containers (such as skips and cages) of mine lifting equipment are generally provided with roller cage shoes. The lifting container swings relative to the cage guide in the up-and-down running process, the rollers on the roller cage ears are impacted by the cage guide, and the impact is buffered by the buffer units on the roller cage ears.
The roller is an important part of the roller cage shoe, and the roller material contacting with the cage guide needs to have enough elasticity and abrasion resistance and cannot damage the cage guide. Most of materials of the roller rolling leather on the existing roller cage shoe are polyurethane, and a left hub and a right hub of the roller are assembled through bolts so as to fix the rolling leather on the hub and generate friction with the rolling leather, and the hub and the roller cannot rotate relatively. In order to increase the resilience and wear resistance of the roller, and to reduce vibration and noise, the polyurethane roller must have a sufficient thickness. During the operation process of the roller, the roller is out of work mainly due to the following two reasons: one is that the relative sliding is easy to generate between the rolling leather and the hub due to insufficient friction force; the other is that when the roller bears complex load, the polyurethane roller leather is easy to generate a large amount of internal heat, the thickness of the roller leather is large, and the heat cannot be dissipated in time, so that the characteristics of the polyurethane roller leather are reduced sharply, and the phenomena of cracking and falling off are generated.
