Abstract

A steel cable braking system features that two braking plates are pressed by springs to clamp a steel cable between said plates for braking the steel cable. It is composed of a base, 4 guide supporters at 4 corners, 4 guide pins fixed to said guide supporters, two braking plates with opposite braking liners, 4 springs respectively installed to 4 angles of upper braking plate, a screw bolt module for combining two braking plates, and two right-angle levers.

Description

technical field [0001] The invention relates to a brake device, in particular to a steel wire rope brake device suitable for a moving component. Background technique [0002] Elevators are becoming more and more popular, and their safety in use is getting more and more attention. In order to prevent elevator accidents, GB7588-2003 "Safety Code for Elevator Manufacturing and Installation" stipulates that elevators should be equipped with upward safety protection devices. The wire rope braking device (or rope clamp) is a kind of braking device in the upward safety protection device. It directly acts on the wire rope and will not cause the wire rope to slip on the traction sheave, so it is more reliable. [0003] Existing commercialized rope grips abroad, such as the H&W company of the U.S., this company has also applied for a patent in China. However, the price of imported rope grippers is far beyond the acceptable level of domestic elevator factories. Simultaneously, this...
