Anti-falling brake-buffer system for mining express elevator

Abstract

An anti-falling brake-buffer system for a mining express elevator comprises brake ropes fixed at the two sides of a car platform sill, one end of each brake rope is fixed at the top of a vertical shaft, the other end of the brake rope is fixed at the bottom of the vertical shaft, and a linkage mechanism is arranged at the bottom of the car platform sill, a buffer is arranged at the top of the brake rope, a tension connector is arranged at the bottom of the brake rope, and a safety tongs of the brake rope, which is fixed on the brake rope and connected with the linkage mechanism, is arranged at the bottom of the car platform sill; and the buffer comprises a pair of inversed progressive safety tongs of the brake rope, a buffer rope connected with the brake rope is arranged in the progressive safety tongs of the brake rope, and a buffer rope clamp is arranged on the buffer rope. According to the anti-falling brake-buffer system for the mining express elevator, the installation is convenient, the buffer force of the brake rope is constant and adjustable, the anti-falling braking is reliable, and the safety of a non-rigid guide rail elevator in high-speed running is improved. The anti-falling brake-buffer system can be acted on the brake rope to play a buffer role, also plays a role of braking reliably when the elevator falls or brakes, so that the safety of the mining express elevator in the high-speed running can be improved.

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
