Description

Technical Field

[0001] The utility model relates to the technical field of shield machines, in particular to a steel plate sealing brush structure for shield machines. Background Art

[0002] The shield tail brush is one of the sealing devices in the shield machine. It is mainly used to block the connection between the shield machine and the outside of the segment to ensure safety and efficiency during construction. The shield tail brush is usually composed of multiple tail brushes to form a closed grease cavity. By filling it with grease, it prevents water and slurry on the back of the segment ring from penetrating into the shield body.

[0003] The shield tail brush is generally composed of front and rear protective plates, a middle protective plate, stainless steel wire, stainless steel mesh and an outer cover plate. The front and rear protective plates, the middle protective plate, stainless steel wire and stainless steel mesh need to be accurately inserted and installed in the outer cover plate and fixed by pins. The front and rear protective plates, the middle protective plate, stainless steel wire and stainless steel mesh need to be aligned with the pin holes in the outer cover plate. Especially when maintaining and replacing the shield tail brush in the underground operating space, the installation site is often limited in space and the working environment is relatively harsh, such as wet, muddy or narrow, which undoubtedly increases the difficulty of installation, making the disassembly and assembly process of the main components of the shield tail brush less convenient, affecting the maintenance and replacement efficiency of the shield tail brush.
