Problems solved by technology

[0003] Due to the separation of components such as the traction machine brake, traction sheave, rope retaining device, and car upward overspeed protection, these products have disadvantages such as high production costs, strict process precision, large external dimensions, large braking inertia, and difficult transportation and installation.
In particular, the current rope retaining device is difficult to prevent the traction wire rope from detaching from the traction sheave rope groove when the elevator rushes to the top, squats to the bottom, and the safety gear operates in emergency situations. difficulty

Embodiment Construction

[0015] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0016] Such as figure 1 , 2 , Shown in 3, a kind of novel traction machine braking device comprises traction wheel 1, braking device, motor 2 and frame 3, and traction wheel, braking device and motor are installed on the frame respectively; Traction wheel The height of the groove walls on both sides of the rope groove is at least not less than the width of the groove; the braking device is arranged outside the traction sheave.

[0017] Further, the traction wheel is integrally formed, and the height of the groove wall is 5mm larger than the width of the groove.

[0018] The brake device is a brake 4 and a brake lining 5 connected to the brake, there are two brake ...

Abstract

The invention provides a novel traction machine brake device, which comprises a traction sheave, a brake device, a motor and a rack, wherein the traction sheave, the brake device and the motor are arranged on the rack respectively; the heights of groove walls on two sides of a rope groove of the traction sheave are not smaller than the width of the groove; and the brake device is arranged outside the traction sheave. According to the novel traction machine brake device, the structure of a traction machine is modified and simplified, and all parts are integrated into a whole, so that the size is reduced, the self weight of the traction machine is reduced, the production cost is decreased, the brake device is easy and convenient to transport and mount, and the probability that a steel wire rope is separated or jumps from the rope groove of the traction sheave when an elevator cage crushes to the top or collapses to the bottom is effectively reduced.

Description

technical field [0001] The invention relates to a novel traction machine braking device, which belongs to the field of braking devices. Background technique [0002] Now known various elevator traction machine braking devices are all designed with independent structures, whether they are external drum type, built-in drum type or shoe type, block type, ventilated disc type, friction disc type and other brakes. The brakes, traction sheave, rope retaining device, car upward overspeed protection device and other components of the traction machine are set independently, and the brake is not directly related to the traction sheave, rope retaining device, upward overspeed protection device, etc. [0003] Due to the separation of components such as the traction machine brake, traction sheave, rope retaining device, and car upward overspeed protection, these products have disadvantages such as high production costs, strict process precision, large external dimensions, large braking i...
