Track power wheel with detachable and replaceable tread

Abstract

The invention discloses a track power wheel with a detachable and replaceable tread. The track power wheel comprises a rim and a spoke, the rim comprises a supporting ring and a rubber tread, a first flange is arranged on the inner side of the outer circumferential face of the spoke, the supporting ring comprises a ring body, and a step face matched with the first flange is arranged at one end of the inner side of the inner circumferential face of the ring body; a second flange is arranged at one end of the inner side of the peripheral face of the ring body, the rubber tread covers the peripheral face of the ring body and the surface of the second flange, a detachable check ring is arranged at the end, close to the outer side of a wheel, of the spoke, the rim is limited between the check ring and the first flange through the check ring, and the spoke is provided with a plurality of radial telescopic pins. The face, facing the outer side of the wheel, of the head end of the radial telescopic pin is a slope face, the face, facing the inner side of the wheel, of the head end of the radial telescopic pin is a vertical face, the radial telescopic pin is provided with a tail end exposed out of the spoke, and a locking groove matched with the radial telescopic pin is formed in the inner circumferential face of the ring body. The track power wheel with is easy to install and replace, does not need special tools, and is high in maintenance efficiency.

Description

technical field [0001] The invention relates to a rail power wheel, in particular to a rail power wheel with removable treads. Background technique [0002] Now rail transit equipment is developing in the direction of miniaturization, integration, and convenience. In recent years, multi-functional rail equipment such as inspection, rescue, and transportation with small rail vehicles as carriers has appeared, and the market prospect is huge. During the use of these rail cars, they must meet the dispatching requirements for the insulation between the car body and the track, so the wheels used are mainly insulated with rubber treads. Due to the special structure of the rail wheel, a rim needs to be provided inside the wheel, so usually the rubber tread needs to cover both the side of the wheel circumference and the outside of the rim. During use, the rubber tread rubs against the rail, and the working conditions are harsh, resulting in a low service life of the tread and high ...

AI Technical Summary

Problems solved by technology

During use, the rubber tread rubs against the rail, and the working conditions are harsh, resulting in a low service life of the tread and a high frequency of equipment maintenance. However, it is difficult to replace the rubber tread covering the wheel circumference and outside the rim, and the maintenance cost of the rail wheel The time is long and the efficiency is low, which further affects the railway construction
