Background

The standard number of the rectangular steel cage guide roller cage shoe published by the State safety production supervision and administration is MT236-2011, the roller cage shoe meeting the standard comprises a bottom frame, a swinging frame, a roller and a buffer device, the swinging frame is connected with the bottom frame through a hinge, the roller is connected with the swinging frame through a revolute pair, a rubber wheel of polyurethane or rubber is arranged on a hub of the roller, the buffer device is arranged between the swinging frame and the bottom frame, the rubber wheel is always close to the steel cage guide along the horizontal direction under the action of the buffer device, the steel cage guide has horizontal thrust, when the steel cage guide is in a place with up and down non-straight and undulated positions, the lifting equipment vibration can be caused, the rubber wheel moves back and forth, the swinging frame swings along with the swinging, the swinging frame transmits the vibration to the buffer device, the elastic element in the buffer device can buffer and absorb vibration, and the rubber wheel is a polyurethane or rubber elastic body and can also buffer and absorb vibration, so that the operation of the lifting equipment tends to be stable. At present, manufacturers basically conform to the standard, but products of all families have characteristics.

In the production process of coal mines, roller cage shoes are often used for installing a guide device which stably runs up and down along a cage guide on a vertical shaft lifting container, and the guide device is one of main components of the lifting container. The roller cage shoe lifting device has the effects that on one hand, the roller cage shoe lifting device is used as a guide wheel for lifting a container to move along a cage guide, on the other hand, the lifting container can be connected, but the quality difference of roller cage shoe manufacturers used at present is large, the roller cage shoes produced by various manufacturers are different, the service life of good quality is long, and various problems are easy to occur when the quality is poor. The service life has great difference and potential safety hazard.
