Description

Technical Field

[0001] The utility model relates to the field of shield construction, in particular to a traction device for shield construction. Background Art

[0002] At present, the commonly used shield traction devices mainly include winch traction devices, hydraulic traction devices and chain traction devices, but these traction devices have some problems that are difficult to ignore in practical applications.

[0003] The winch traction device has certain applications in shield construction, but its traction capacity has obvious limitations. When the shield machine needs to pass through complex geological conditions (such as hard rock formations, high-resistance mixed formations, etc.) or excavate long distances, the traction force provided by the winch is often unable to meet the needs. Moreover, the wire rope that the winch traction relies on is prone to wear problems during use. Due to the harsh shield construction environment, the wire rope is subjected to long-term stretching, bending and friction with surrounding components, and its wear rate is accelerated. Once the wire rope is severely worn, it will not only reduce the reliability of the traction device, but may even cause safety accidents, affecting the continuity and safety of shield construction.

[0004] Therefore, it is necessary to provide a shield traction device to solve the above technical problems. Utility Model Content

The use of the lifting rod 31 is convenient for adjusting the upper and lower heights of the entire device. When the movable sleeve 42 is used on the surface of the fixed rod 41, it can drive the two wiping components 5 to move left and right by moving the steel wire left and right. A mounting through hole that is compatible with the external thread block 52 is provided inside the mounting frame 43. The use of the external thread block 52 and the threaded sleeve 53 is convenient for regular disassembly and replacement of the wiping roller 51.
