Problems solved by technology

[0003] However, this structure may cause a bias force during braking because the center of the brake band does not coincide with the center of the brake disc, resulting in a large bending load on the brake shaft
As a result, the part of the brake band is severely worn, while the other part is not worn.

Embodiment Construction

[0022] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the principles of the present invention, and are not intended to limit the present invention.

[0023] Such as figure 2 As shown, in the embodiment of the present invention, a brake is provided for elevator braking, specifically a block brake. The brake is provided with a driving base 1 and a braking assembly 2 , and a braking arm 3 is installed on the driving base 1 .

[0024] According to actual application conditions, preferably, there are two groups of brake assemblies 2 , and the two groups of brake assemblies 2 are symmetrically distributed on both sides of the drive base 1 .

[0025] The brake assembly 2 includes a brake arm 3 and a b...

Abstract

The invention relates to a brake. The brake is provided with a base and a brake assembly; the brake assembly comprises a brake arm and a brake block, the brake arm is mounted on the base, the brake block can be rotatably arranged at one end of the brake arm, and the brake block can freely rotate after being mounted; it can be ensured that the brake block can be tightly attached to a brake disc. During braking, the brake cannot generate eccentric force, balanced brake is achieved, and mounting and adjusting are convenient.

Description

technical field [0001] The invention relates to a brake device for an elevator, in particular to a brake. Background technique [0002] Such as figure 1 Shown, in the prior art, brake arm device is made up of brake arm 3 ' and non-asbestos brake band 4 '. Stick together with special adhesive between brake arm 3 ' and non-asbestos brake band 4 '. [0003] However, this structure may cause a bias force during braking because the center of the brake band does not coincide with the center of the brake disc, resulting in a relatively large bending load on the brake shaft. As a result, the local wear of the brake band is serious, while the other parts are not worn. Contents of the invention [0004] In order to overcome the defects of the prior art, the purpose of the present invention is to provide a brake block that can rotate freely to ensure that the brake block and the brake disc are tightly fitted and can balance the brake. [0005] To achieve the above object, the pre...
