Rail Brake with Guide Wheels

摘要

A braking system is provided for rail equipment supported for rolling movement on the rails of a railway. The braking system includes a pair of braking elements arranged to be supported laterally spaced apart on the rail equipment for engaging the respective rails of the railway. Each braking element includes an upper brake block for selectively engaging a top side and a side brake block for selectively engaging an inner side of the corresponding rail. Actuators are provided for urging the braking elements downward and outward in relation to the rail equipment. The actuators engage the braking elements with the respective rails to provide a wedging action between respective inner sides of the rails. This arrangement provides considerable braking force using a relatively simple construction.

1. A braking system for rail equipment which is arranged to be supported on a pair of rails for movement in a longitudinal direction along the rails, the braking system comprising:
a pair of carriage assemblies, each carriage assembly comprising a frame member and a pair of guide wheels rotatably mounted on the frame member at longitudinally spaced positions; rail equipment mounting means arranged to support the carriage assemblies on the rail equipment such that the carriage assemblies are movable between a railway position in which the guide wheels of the pair of carriage assemblies are arranged for rolling engagement along respective ones of the rails and a roadway position in which the carriage assemblies are spaced upwardly from the railway position; a braking component comprising at least one brake block supported on each carriage assembly such that said at least one brake block is movable relative to the respective carriage assembly between an engaged position in which said at least one brake block engages the respective rail in a braking action and a disengaged position in which said at least one brake block is disengaged from the respective rail while the carriage assembly remains in the railway position; and an actuator arranged to selectively urge the brake blocks of the carriage assemblies towards the engaged position.
