Abstract

The invention discloses a traction machine brake. The traction machine brake comprises a brake state and a brake release state, wherein in the brake state, brake shoes make complete contact with brakesurfaces, and in the brake release state, the brake shoes are completely separated from the brake surfaces; the traction machine brake further comprises displacement measuring devices, the displacement measuring devices comprise first displacement sensors arranged on brake arms, the first displacement sensors are used for measuring the real-time brake release distances between the brake shoes andthe brake surfaces, the first displacement sensors are connected with control devices, and the first displacement sensors transmit the real-time brake release distances between the brake shoes and the brake surfaces in the brake release state to the control devices; and preset modules and comparison modules are arranged in the control devices, the minimum brake release distances between the brakeshoes and the brake surfaces are preset in the preset modules, the comparison modules are used for comparing the real-time brake release distances with the minimum brake release distances, and the control devices control brake release devices to act according to comparison results.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a traction machine brake. Background technique [0002] The brake release gap of the traction machine in the prior art cannot be automatically detected, and it is generally measured manually with a feeler gauge, which is time-consuming and cumbersome, especially difficult to operate at the hoistway installation site, and it is impossible to automatically adjust the push of the electromagnet according to the measured value distance, and then adjust the release clearance. Contents of the invention [0003] In view of this, in order to overcome the defects of the prior art, the object of the present invention is to provide an improved traction machine brake, which can automatically adjust the moving distance of the push rod according to the brake release clearance. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: ...
