Abstract

The invention relates to elevator brake safety tongs which comprise a base. A first brake block and a second brake block are arranged on the base. A brake groove is formed in the side, away from the second brake block, of the first brake block. A locating cylinder is arranged on the base and provided with a rotatable brake wheel. The brake wheel comprises a cam and an eccentric round wheel which are arranged up and down and are fixedly connected. The outer edge of the eccentric round wheel and the brake groove are matched so as to drive the first brake block to move towards the second brake block. The base radius of the cam is larger than or equal to the radius of the eccentric round wheel, and the cam can penetrate the first brake block to abut against and press an elevator guide rail. According to the elevator brake safety tongs, brake drive is achieved through dynamical friction between the cam and the elevator guide rail till the first brake block and the second brake block clamp the elevator guide rail when the brake wheel stops rotation; and by means of the structure, the safety tongs can be effectively prevented from failing, and reliability is high.

Description

technical field [0001] The invention relates to elevator safety control technology, in particular to an elevator brake safety gear. Background technique [0002] The safety gear is an important safety component of the elevator equipment. It can play a role in safety protection when the elevator overspeeds or stalls. The action of the safety gear device is to make the rope clamp clamp the speed limiter rope through the action of the speed limiter, and then go down with the car. Running, the speed limiter rope pulls the safety gear linkage mechanism, and the safety gear linkage mechanism moves to drive the safety gear braking element to contact the guide rail, so that the safety gear on both sides of the guide rail is tightened on the guide rail at the same time, so that the car is stopped. The safety gear is generally installed on the bottom beam of the car or the columns on both sides. When the safety gear is not in action, the brake block of the safety gear and the working ...
