Title:
ANNULAR BRACING BOOT PROPULSION SYSTEM FOR VERTICAL SHAFT SINKING
Document Type and Number:
WIPO Patent Application WO/2019/128921
Kind Code:
A1
Abstract:
Disclosed is an annular bracing boot propulsion system for vertical shaft sinking, the system comprising an intermediate column (8), several boot plates (1) and several bracing cylinders (2), wherein the boot plates (1) and the bracing cylinders (2) are connected end-to-end to form an annular structure, each of the boot plates (1) is connected to the intermediate column (8) via a fixed torque beam (6) and a telescopic torque beam (5), and one end of the telescopic torque beam (5) is sheathed in the fixed torque beam (6), while the other end is movably connected to the boot plates (1); the inner wall of the boot plate (1) is connected with a propulsion cylinder (3), and one end of the propulsion cylinder (3) is connected to the boot plate (1), while the other end is connected to the fixed torque beam (6); and both the bracing cylinder (2) and the propulsion cylinder (3) are connected to a controller. The bracing cylinder of this system uses an annular arrangement and is connected to the intermediate column of a bracing boot device via the torque beams to provide the reaction torque and propulsion force of the bracing boot device. The structure of the system is simpler, the processing cost of the bracing boot is lower, and the inner space of a tunnel or vertical shaft is larger, thus making same more conducive to material transportation and equipment layout.
