Description

Technical Field

[0001] The utility model relates to the field of shield machines, in particular to a shield machine bracket. Background Art

[0002] According to their working principles, shield machines are generally divided into hand-dug shields, extrusion shields, semi-mechanical shields (local air pressure, global air pressure) and mechanical shields (open-chest cutting shields, air pressure shields, slurry pressure shields, earth pressure balance shields, hybrid shields and special-shaped shields). The basic working principle of a shield machine is a cylindrical steel component. The shell of the cylindrical component is the shield, which can provide temporary support for the excavated tunnel section that has not yet been lined, withstand the pressure of the surrounding soil layers, and sometimes withstand the groundwater pressure and keep the groundwater out. Excavation, soil discharge and lining operations are carried out under the cover of the shield.

[0003] At present, shield machines usually use supports for work. The current supports are adjusted by hydraulic rods, but lack a structure to limit the support. As a result, the hydraulic rods are subjected to greater pressure. Moreover, when the hydraulic rods are damaged, the support will shrink under pressure, and major accidents are prone to occur. Therefore, technical personnel in this field provide a shield machine support to solve the problems raised in the above background technology. Utility Model Content
