Anti-falling brake-buffer system for mining express elevator

Abstract

Disclosed is a fall prevention brake buffering system for high-speed mine lift, including brake ropes (2) fixed on two sides of a car (5). One end of the brake rope (2) is fixed on the top part of a vertical well (6), and the other end is fixed on the bottom part of the vertical well (6). A linkage mechanism (11) is arranged at the bottom of the car (5). A buffer (1) is arranged at the top of the brake rope (2), and a tension connector (4) is arranged at the bottom of the brake rope (2). A brake rope safety tong (3) fixed on the brake rope (2) and connected with the linkage mechanism (11) is arranged at the bottom of the car (5). The buffer (1) includes an inverted brake rope gradual safety tong (8) with a buffering rope (9) provided therein and connected with the brake rope (2). A buffering rope clip (10) is arranged on the buffering rope (9). The system is convenient to install, and the buffering force of the brake rope is constant and adjustable. The system realizes reliable fall prevention brake function, greatly improves safety performance during high-speed operation of a lift with non-rigid rails, and increases safety performance during high-speed operation of a mine lift.

Description

technical field [0001] The invention relates to an anti-drop brake buffer system for a mine-used high-speed elevator, which is especially suitable for the car anti-drop brake buffer system guided by the flexible guide rail of the mine-used high-speed elevator, and also suitable for other flexible-guided low-speed elevators and lifting systems. technical background [0002] The currently widely used elevator car protection system is mainly applied to elevators using rigid guide rails. The safety gear of the conventional elevator car overspeed stall safety protection system can only act as a brake on the rigid guide rails; Deformable underground engineering elevators can easily cause the safety gear, which can protect the car from falling, to malfunction, causing the car to be stuck in the shaft, which brings huge safety hazards to the operation of the elevator. In order to ensure the safety of elevator operation, for elevators guided by non-rigid guide rails, th...

AI Technical Summary

Problems solved by technology

However, due to the increased kinetic energy of high-speed elevators, it is easy to cause problems such as large braking deceleration of the car during the anti-fall braking process. The existing non-rigid guide rail car overspeed stall protection system is suitable for low-speed elevators, and there is no such system at present. Anti-drop brake buffer system for mine high-speed elevators, so there is an urgent need for a brake buffer system for mine high-speed elevator anti-drop
