Abstract

The invention relates to a brake which is fixed on the top of a lift car of an elevator guided by a left side guiding track and a right side guiding track. The brake comprises brake pieces, linkage parts and a driving part. The driving part drives the linkage parts to control the brake pieces to be attached to the guiding tracks for braking. The driving part comprises a hanging part and an elastic piece. The two ends of the elastic piece are connected with a first connecting point and a second connecting point of the hanging part. The linkage parts are provided with at least two clinchers which are distributed on the two sides of the guiding tracks. The braking pieces are arranged on the clinchers. After a steel wire rope is broken, the distance between the first connecting point and the second connecting point is compressed through the resilience force of the elastic piece, so that a hanging part body deforms, driving feet drive the clinchers to move along with deforming of the hanging part body, and the braking pieces are driven to clamp the guiding tracks. According to the brake, the number of structure components is small, structure is simple, production cost is low, and the elevator which falls down because of fault can be braked timely and reliably.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a brake of a car elevator. Background technique [0002] A brake is a device that has the functions of decelerating, stopping or keeping a moving part (or moving machinery) in a stopped state. It is a mechanical part that stops or slows down the moving parts in the machine. Commonly known as brakes, brakes. [0003] The patent document discloses a lifting tong device for an elevator car with the publication number CN102862893A, wherein the existing car safety tongs working system consists of a lifting mechanism (9), a speed-limiting steel wire upper end (5) and a car safety tongs (11) is formed, and the car safety gear (11) is fixed on the car. When the car falls over-speed, the speed limiter in the elevator machine room will hold the upper end of the speed-limiting steel wire (5), driving the lifting mechanism (9) and the safety gear wedge (12) to move upward relative t...
