Abstract

A brake cover of an elevator hoist is provided, wherein the elevator hoist (1) has a motor (2) and a brake (3) for braking the motor, and the motor is arranged in the elevator pit at the bottom of the lift passage for driving its The sheave of the sling for raising and lowering the elevator car is wound on it, and the brake cover is mounted on the flange (2b) of the motor to cover the brake, wherein the brake cover has a lower cover (10a), a middle The plate (10b) and the upper cover (10c), the lower cover is fixed so that its end face and the side of the flange are closely together to cover the lower part of the motor, and the lower surface of the middle plate is in close contact with the upper surface of the lower cover Together, and its end faces are in close contact with the sides of the flange, the upper cover is fixed so that its lower surface is in close contact with the upper surface of the middle plate for covering the top of the brake.

Description

technical field [0001] The present invention relates to a brake cover of an elevator hoist, in particular to a brake cover of an elevator hoist, which has a waterproof function for a brake of a motor arranged at the bottom of an elevator passage. Background technique [0002] As the brake cover of the traditional elevator hoist, for example, a brake cover covering the braking device is disclosed in Patent Document 1. The brake cover is closely attached to the end face of the motor body, that is, the edge of the motor body. When water enters the bottom of the lifting passage, it can waterproof the hoist installed at the bottom, especially the brake of the hoist. [0003] In addition, as a conventional technology, there is also a brake cover used to cover the brake device is divided into upper and lower parts, and one end surface of each cover is closely connected to the edge of the motor, and the other end surface is connected to the edge of the motor. The other shroud is sn...
