An intelligent control fall arrester for flexible tanks

Abstract

The invention discloses an intelligent control falling protector for a flexible cage guide, and belongs to the technical field of coal mine safety. The intelligent control falling protector is a hydraulic intelligent control catching device capable of regulating braking force according to needs, and is mainly applied to a perpendicularly lifting man cage or a man-goods cage. The falling protector is characterized by consisting of three sets of systems, namely a mechanical system, an electric control system and a hydraulic control system, the structure of the whole device completely consisting of mechanical components in the prior art is changed, and the braking process of the whole device is completed by the hydraulic control system. In the braking process, the braking force can be regulated, so that the problems that the braking force cannot be regulated in the braking process, braking process is excessively high in rigidity, the braking distance is too short, a man in the cage feels uncomfortable and is even possibly injured, the catching success rate cannot be ensured and a checking process is complex in the prior art are solved. The falling protector has the greatest advantages that the braking process can be regulated, the braking force is strong, the cage can be controlled to be slowly parked in the lowest layer of the cage guide according to needs, and good convenience is brought to the evacuation of the man in the cage and overhauling.

Description

technical field [0001] The invention relates to a flexible tank road intelligent control fall arrester, which belongs to the technical field of mountain and mine safety. The single-layer or double-layer cages installed on it overcome the disadvantages that the braking force of the existing cage fall arresters is generally not adjustable, and it is a replacement product for the existing cage fall arresters. Background technique [0002] Most of the auxiliary transportation in large and medium-sized mines is realized by using cages. The cages are mainly used in vertically lifted auxiliary shafts to lift underground workers, equipment, maintenance materials, and auxiliary materials such as coal gangue. The tank track is installed in the auxiliary shaft to guide the cage to run up and down. There are two types of tank tracks, flexible and rigid. The flexible tank track uses steel wire rope, and the rigid tank track generally uses T-shaped steel or steel rails. If the vertical l...

AI Technical Summary

Problems solved by technology

[0005] 1. The entire device is composed of mechanical parts, and the success rate of arrest cannot be guaranteed. It is required to check the braking force and braking process at least once a year, and the verification process is complicated.

[0006] 2. The location of the stop is not optional. The tank cage is often stopped in mid-air in an accident state, and it is very difficult to evacuate the tank crew and maintenance personnel for maintenance.

[0007] 3. The braking force cannot be adjusted during the braking process, the braking process is too rigid, and the braking distance is too short, which makes the tank crew feel very uncomfortable and may even cause injury accidents

[0008] 4. Serious damage to the brake parts. Due to the large potential energy of the cage, the rigidity of the braking process is too large, the braking distance is too short, and the wedges are severely worn. According to the regulations, the wedges must be replaced several times after braking. Three decoupling checks

[0009] 5. The recovery process is relatively difficult and cumbersome
