Device for installing and detaching support shoes of jacks of shield tunneling machine and method for installing and detaching support shoes

Abstract

The invention relates to a device for installing and detaching support shoes of jacks of shield tunneling machines and a method for installing and detaching the support shoes. The device comprises a support mechanism and a hoisting head, the support mechanism consists of a Y-shaped support framework, small shoe jacking support blocks, a large shoe jacking support block, a support shoe connecting plate and a mounting tube, a rectangular support longitudinal beam and a trapezoidal support crossbeam are abutted to form the Y-shaped support frame, the small shoe jacking support blocks are arranged at two ends of the upper surface of the trapezoidal support crossbeam, the large shoe jacking support block is arranged on the upper surface of the rectangular support longitudinal beam, the supportshoe connecting plate is arranged on the other end surface of the rectangular support longitudinal beam, a connecting hole is disposed on the support shoe connecting plate, the mounting tube is embedded at a joint of the trapezoidal support crossbeam and the rectangular support longitudinal beam, a big-end-up stepped cylindrical hole is arranged in the mounting tube, and the hoisting head is inserted into the stepped cylindrical hole and fixed by a bolt A. The device and the method have the advantages that installation efficiency and detachment efficiency of the support shoes can be greatly improved, safety performance is high, and the device and the method can be widely applied to installation and detachment of the support shoes of the shield tunneling machines.

Description

technical field [0001] The invention relates to an auxiliary device for installing and dismounting a jack shoe of a shield machine and a method for using the same. Background technique [0002] With the development and utilization of large underground spaces, the application of shield machines is becoming more and more extensive. However, due to the structural design of most shield machines, such as NFM shield machines, it is required that every time the shield machine is assembled and disassembled, It is necessary to install and disassemble the jack stand shoes, and due to the large number of jack stand shoes (generally 10), the weight of a single stand shoe is heavy (about 550kg), and the installation positions of the jack stand shoes are different (height , different angles), limited working space, etc., so through the traditional method of manual installation or disassembly by pulling down the chain, all the installation or disassembly of the boots is completed, the wor...
