Full-automatic regulation device for mine hoist brake shoe interval

Abstract

The invention discloses a full-automatic regulation device for a mine hoist brake shoe interval. The full-automatic regulation device for the mine hoist brake shoe interval comprises a brake body, a large gear ring, a worm, a micro reducer, a micro transmission motor and a displacement sensor; the large gear ring is in threaded connection to the inside diameter of one end of the brake body and isengaged with the worm arranged at the outer part of the brake body; the micro reducer is connected to the tail part of the worm and is fixedly installed on the surface of the brake body; the micro transmission motor is connected to the micro reducer; the outer part of the brake body is provided with the displacement sensor; and the brake body is provided with a brake component. The full-automaticregulation device provided by the invention is simple in design structure as well as convenient and rapid to operate, can perform monitoring on the wear quantity of a brake shoe, replaces the traditional manual regulation manner to perform regulation on the wear quantity of the brake shoe when the brake shoe is worn, improves the accuracy and increases the speed in the brake shoe regulation process, lowers the physical power consumption of a worker and reduces occurrence of safety hidden dangers.

Description

technical field [0001] The invention belongs to the technical field of hoister parts design, and in particular relates to a fully automatic adjustment device for brake shoe clearances of mine hoists. Background technique [0002] The task of the mine hoisting system is to lift coal, gangue, lowered materials, lift personnel and various mining equipment. It is the throat link of the mine production system and plays a very important role in the mine production. Once a failure occurs, it will affect the production at least, and cause serious loss of national property, and even cause serious personal casualties. In the coal mine hoisting process, the braking device of the mine hoist is one of its most important components. The various protection devices on the hoist serve the brakes. Therefore, the quality of the braking device of the mine hoist directly It affects the production efficiency of the entire mine, and even relates to the safety of coal mine production. [0003] Mi...

AI Technical Summary

Problems solved by technology

If the installation gap of the brake shoe does not meet the design requirements or the wear gap of the brake shoe increases and exceeds the range stipulated in the "Coal Mine Safety Regulations" or the brake shoe is worn excessively and the brake shoe is not replaced in time, the braking performance will be unstable. Thus affecting the normal operation of the lifting system

[0004] The traditional method of existing brake shoe clearance adjustment is manual adjustment. Manual adjustment has many inconveniences and potential safety hazards. It mainly has the following defects: 1. Manually adjusting the brake shoe clearance requires customizing specific special tools; 2. Manual adjustment ...
