Car retarder with detachable steel rail carriers

Abstract

The invention provides a car retarder with detachable steel rail carriers. One side, close to the interior of a rail, of a rail carrying groove is open, and cantilever blocks are arranged on the other side, close to the exterior of the rail carrying groove; the shortest distance between the two sidewalls of the rail carrying groove is smaller than the width of the bottom of a traveling rail; a lug is arranged on the front end of an inner brake caliper at a shaft hole; a wear-resistant hard alloy is welded on the lower end face of the lug, and the lower end face of the lug is matched with the upper end face of the bottom of the traveling rail in shape; an outer brake caliper does not contact with the traveling rail. The car retarder with the detachable steel rail carriers has the advantages that the traveling rail does not need to be demounted when the steel rail carriers are mounted and replaced, when one steel rail carrier in the middle of the car retarder is replaced independently, all the steel rail carriers on one side do not need to be completely detached, and therefore, the workload of mounting and repair is reduced, besides, when the brake calipers are mounted, the steel rail carriers can be still suspended on the traveling rail by use of the cantilever blocks on the outer side, and therefore, the case that an auxiliary supporting block needs to be placed at the bottom of a full-open steel rail carrier is avoided, and convenient mounting can be realized.

Description

technical field [0001] The invention belongs to the field of railway reducers, in particular to a vehicle reducer with detachable rail bearing seats. Background technique [0002] The brake caliper group in the traditional gravity vehicle reducer is suspended on the upper plane of the rail bottom of the running rail (also known as "basic rail") by the protrusion of the rail bearing seat itself. The rail bearing is an integral structure, and it must be installed Go in from one end of the track. Usually, 12 to 18 brake caliper groups are installed on a 25m running rail. When the running rail is not moving, the rail bearing is not removable. During use, if one of the rail bearings needs to be replaced, the running rail must be removed from the line and raised, and then the rail bearings in front (or behind) of the damaged rail bearing are withdrawn from the running rail, and then Reinstallation is a lot of work. [0003] In order to reduce the difficulty of replacing the ra...

AI Technical Summary

Problems solved by technology

Since the brake caliper with bumps supports and suspends the entire brake caliper group, when the brake caliper is replaced, the rail bearing cannot be independently suspended on the running rail, and pads need to be provided between the bottom surface of the rail bearing and the sleeper plate After the brake caliper is installed, the pad is removed, which increases the difficulty of replacing the brake caliper
