Problems solved by technology

[0005] The present invention provides a two-way safety gear for an elevator and its elevator device. One of the purposes is to have the characteristics of interlacing the surface of the brake pads to increase the friction force, so as to solve the problem that the high temperature generated by the friction will melt the brake during emergency braking. The surface of the brake pads causes the problem of slipping on the surface of the brake pads; another purpose is to solve the problem that the connecting rod of the two-way caliper breaks due to the inability to buffer it during a collision, so as to relieve the external impact force of the two-way caliper when it collides drop effect

Abstract

The invention discloses bidirectional safety tongs for an elevator and an elevator device, and relates to the technical field of bidirectional safety tongs. The bidirectional safety tongs for the elevator comprise bidirectional safety tongs bodies, wherein pushing and fixing mechanisms are fixedly mounted on the inner surfaces of the bidirectional safety tongs bodies; telescopic combining mechanisms are movably mounted on the outer surfaces of both sides of the pushing and fixing mechanisms; a safety brake mechanism is fixedly connected with one end of each telescopic merging mechanism and comprises a fixing housing I; and a friction brake pad is fixedly connected with the inner wall surface of each fixing housing I. The outer surfaces of T-shaped blocks are pushed through extending and clamping columns; the extrusion in pushing heads is achieved through the cooperation with rebound lines; pushing heads are pushed through the elastic force of the rebound lines to one side; the friction force of the friction brake pads is increased by pushing the friction brake pads; the characteristic of pushing the friction brake pads is achieved; the problem that the friction force of the brake pads is reduced due to the insufficient pressure of the friction brake pads is solved; and the effect of increasing the friction force by pushing the friction brake pads is achieved.

Description

technical field [0001] The invention relates to a device of a two-way safety gear, relates to the technical field of the two-way safety gear, in particular to a two-way safety gear for an elevator and an elevator device thereof. Background technique [0002] The safety gear is the safety protection device of the elevator. The elevator safety gear device is controlled by the speed limiter. When the elevator speed exceeds the limit speed set by the elevator speed limiter, or when the suspension rope breaks and relaxes, It is a safety device that the car stops in an emergency and is clamped on the guide rail. It provides effective protection for the safe operation of the elevator. It is generally installed on the car frame or the counterweight frame. Safety gear is divided into one-way safety gear and two-way safety gear. There are following problems at prior art: [0003] 1. The brake layers on the existing two-way safety pliers are all single-sided brake pads, and the sorte...
