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.
