Abstract

The invention belongs to the technical field of safety gear, especially the safety gear which can be adjusted by itself through the instantaneous average deceleration. Aiming at the problem that the existing elevator cannot perform average deceleration safely, quickly and effectively when the speed is too fast, the following proposal is now proposed. Including the frame box, the front of the frame box is provided with a guide rail gap, and the guide rail is movably connected to the guide rail gap, and the top of the frame box is opened with two slide holes, and the two slide holes are slidingly installed with pull rods, and the bottom of the two pull rods are movable. A lever mechanism is connected, and the two lever mechanisms are misplaced. A support seat is connected to the lever mechanism, and a friction deceleration mechanism and a guide mechanism are connected to the support seat. The guide mechanism is connected to the inner wall of the frame box, and the top of the frame box is provided with a lever unit. , the lever unit is rotatably connected with two pull rods, and a push rod cylinder is arranged on the top of the frame box. The invention can automatically decelerate evenly when the elevator speed is too fast.

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 ...
