Lifting method for flipping bracket and shield main drive

Abstract

The invention relates to the field of tunneling construction of tunnel shield machines, and discloses a turnover bracket and a hoisting method of a shield main drive. The turnover bracket comprises alifting frame and a support frame which are separately connected to the two opposite sides of the shield main drive; the lifting frame is mainly used for connecting a lifting hook of a crane, and thesupport frame is mainly used for assisting in turnover in the lifting process, and preventing bumping during lifting; and the turnover bracket can be used for protecting the shield main drive in the whole lifting and shaft hoisting process. According to the hoisting method of the shield main drive, the shield main drive can be lifted easily, and the turnover and whole lifting process can be achieved by one crane only; and the lifting space is saved.

Description

technical field [0001] The invention relates to the field of excavation and construction of a tunnel shield machine, in particular to a hoisting method for an overturning bracket and a main drive of a shield machine. Background technique [0002] As a relatively common method in tunnel construction, the shield method is generally used in the construction of urban rail transit, highway tunnels, and comprehensive utility corridors. In recent years, my country has vigorously developed infrastructure construction, and is now the country with the largest number of shield machines. The diameter of shield machines is generally 6m, 8m, 10m and above, and the 6-meter diameter shield machine is used for urban rail transit construction. In recent years, my country's highway tunnel construction has also gradually increased the intensity of the shield method, so that the ultra-large shield machine over 10 meters has a broad application platform. [0003] The shield machine is a large and...

AI Technical Summary

Problems solved by technology

[0006] 1. Higher lifting capacity requirements for lifting equipment;

[0007] 2. Two super-large lifting equipment are required, and a large enough field hoisting platform area is required;

[0008] 3. The operator of the lifting equipment has high requirements, and the operator needs to have sufficient experience and cooperate with each other;

[0009] 4. There is no protection for the main drive of the shield machine when hoisting, and the hoisting stability is insufficient
