Abstract

The invention belongs to the technical field of safety tongs, and particularly relates to safety tongs capable of being automatically adjusted through instantaneous average deceleration. The problem that when the speed of an existing elevator is too high, average deceleration cannot be safely, rapidly and effectively carried out is solved. According to the following scheme, the safety tongs comprise a frame box, a guide rail notch is formed in the front face of the frame box, a guide rail is movably connected into the guide rail notch, two sliding holes are formed in the top of the frame box, pull rods are slidably installed in the two sliding holes, lever mechanisms are movably connected to the bottoms of the two pull rods, the two lever mechanisms are arranged in a staggered mode, supporting seats are connected to the lever mechanisms, and friction speed reducing mechanisms and guide mechanisms are connected to the supporting seats. The guide mechanisms are connected with the inner wall of the frame box, a lever unit is arranged at the top of the frame box and rotationally connected with the two pull rods, and a push rod air cylinder is arranged at the top of the frame box. When the speed of the elevator is too high, the elevator can be automatically and uniformly decelerated.

Description

technical field [0001] The invention relates to the technical field of safety gear, in particular to a safety gear that can be self-adjusted through instantaneous average deceleration. Background technique [0002] The elevator safety gear device is under the control of 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 will stop the car in an emergency and clamp it on the guide rail. A safety device on the elevator, which provides effective protection for the safe operation of the elevator, and is generally installed on the car frame or counterweight frame. [0003] Existing elevators cannot perform average deceleration safely, quickly and effectively when the speed is too fast. Contents of the invention [0004] The purpose of the present invention is to solve the defect that the existing elevator cannot perform average deceleration safely, quickly and effectively when ...
