AI Technical Summary

Technical Problem

In existing TBM tunnel construction, traditional passing platforms suffer from low transportation efficiency in sections with poor geological conditions due to insufficient traction, failing to meet the continuity and adaptability requirements of complex tunnel construction.

Method used

Design a dual-mode drive self-propelled TBM tunnel passing platform. By combining the detachable structure of the traction beam assembly and the support roller with the hydraulic power system, the platform can be towed by the TBM in normal sections and self-driven by the hydraulic cylinder in high-resistance sections, thus having a dual-mode drive function.

Benefits of technology

To ensure the continuity of tunnel transportation operations and construction safety, improve construction efficiency, reduce frictional resistance, extend equipment life, and enhance construction adaptability and safety.

Abstract

A dual-mode driving self-propelled TBM tunnel staggering platform comprises traction beam assemblies arranged on the left side and the right side, the traction beam assemblies are connected with supporting equipment on the rear portion of a TBM through upper traction pins and lower traction pins, supporting wheels are arranged at the ends, away from the TBM, of the traction beam assemblies, and the supporting wheels are supported on TBM trolley steel rails and connected with hydraulic oil cylinders through connecting pieces. The other end of the hydraulic oil cylinder is connected with a second traction beam, the second traction beam is fixed to the platform frame, a hydraulic power system and an operation control position are arranged on the platform frame, and the hydraulic power system is in through connection with the hydraulic oil cylinder through a hydraulic pipeline. According to the side hanging cage type movable construction platform for rock anchor beam anchor cable tensioning, the problem that traction force is insufficient easily occurs in a bad section can be solved, the side hanging cage type movable construction platform can be pulled by a TBM to run in a common section and can be switched to be driven by the platform to run in an autonomous hydraulic mode in a bad geological section, and therefore continuity and stability of a conveying chain are guaranteed.
