Abstract

The invention relates to a braking device, which comprises a safety gear, a first bracket arranged on the safety gear, a horizontal shaft connected to the first bracket in rotation, a swing arm with an operating end and a control end arranged on the horizontal shaft, fixed on The first limit on the first bracket and on the moving track of the control end, the second limit hinged on the first bracket, and the one set on the horizontal axis for pushing the control end to rotate away from the first limit A torsion spring, a slide block slidingly connected to the body of the safety gear, a pull rod connected to the slide block and the operating end of the swing arm at both ends, and a pulling device arranged on the safety gear are used to move the second limit from the control end The electromagnet that is pushed away on the movement track and the telescopic part that is connected to the first bracket and the second limiter at both ends are used to pull the second limiter to move in a direction close to the swing arm, etc. The invention is used for emergency braking of elevator cars and lifting garages, etc., and has the characteristics of simple structure, fast response speed and the like.

Description

technical field [0001] The invention relates to the technical field of stall braking, in particular to a braking device. Background technique [0002] The safety gear is the safety protection device of the elevator. 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 [0003] Existing safety gear mostly adopts a mechanical linkage control method, the structure is relatively complex, and limited by a long transmission path, there is a certain lag in the start-up time. Contents of the invention [0004] In view of the deficiencies in the prior art, the object of the present invention is to provide a braking device capable of rapid braking. [0005] Above-mentioned purpose of the present invention is achieved through the following ...
