Disclosed is a fall prevention brake buffering system for high-speed mine lift, including brake ropes () fixed on two sides of a car (). One end of the brake rope () is fixed on the top part of a vertical well (), and the other end is fixed on the bottom part of the vertical well (). A linkage mechanism () is arranged at the bottom of the car (). A buffer () is arranged at the top of the brake rope (), and a tension connector () is arranged at the bottom of the brake rope (). A brake rope safety tong () fixed on the brake rope () and connected with the linkage mechanism () is arranged at the bottom of the car (). The buffer () includes an inverted brake rope gradual safety tong () with a buffering rope () provided therein and connected with the brake rope (). A buffering rope clip () is arranged on the buffering rope (). 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.

A mining elevator carrying platform and carrying method, the platform comprises a power system () and a four-rod carrying device (), a rotating rod () connected with the power system () is set on the carrying device (); the power system () comprises a flameproof motor (-), a upper-limited switch (-), a down-limited switch (-) and a main pulley (-), the flameproof motor (-) is connected with the main pulley (-) through a main steel cable (-), a baffle (-) is set on the main steel cable (-), a double cable channel is set on the main pulley (-), and the main pulley (-) is connected with a sub-pulley (-) by a sub-steel cable (-), a sliding plate (-) is set on the sub-steel cable (-), and a sliding rod (-) is set on the sliding plate (-). The main pulley (-) is driven to rotate by the flameproof motor (-) through the main steel cable (-), thus the sub-pulley (-) is driven to rotate. The sliding rod (-) moves in a strip-opening sliding slot in the rotating rod () by the sliding plate (-) moving up and down, then the rotating rod () and a carrying plate (-) are driven to move circumferentially. A rocker (-) is rotated around a supporting bracket (-) driven by a connecting rod (-), thus a credible carrying platform in multi-plane is realized. The platform is simple in structure, controlled accurately, convenient to be fixed and maintained, operated stably and reliably, and has the self-locking function.
