Description

Technical Field

[0001] The utility model relates to the technical field of brake friction blocks, and more specifically to an adjustable brake friction block for a grooved rail. Background Art

[0002] Rail transit trains have large mass and inertia, but relatively small friction between wheels and rails. Therefore, installing protective equipment such as car stops at the end of the line is a very necessary passive safety measure.

[0003] The main function of the train stopper is to prevent the train from running off the track when it loses control unexpectedly, to prevent personal injury and damage to vehicles and other facilities, and to ensure operational safety.

[0004] In the early days, the national railway system employed earth mound-type car stops, curved track-type car stops, mortared stone or concrete car stops, and other types. These types of car stops are rigid and fixed, with the point of contact (or impact) with the uncontrolled vehicle located on the vehicle's bogie or wheels. Their structural characteristics make them extremely ineffective at absorbing the uncontrolled vehicle's kinetic energy, making them highly susceptible to vehicle damage or derailment. Railway authorities are gradually replacing these types of car stops with sliding car stops.

[0005] When the existing adjustable brake friction block is installed on the groove rail, it cannot ensure the fit between the groove rail and the groove rail, which easily leads to unstable installation. Therefore, a new technical solution is needed to solve the problem. Utility Model Content
