Description

Technical Field

[0001] This invention relates to the technical field of tunneling machines, specifically to a combined TBM (Tunnel Boring Machine) slag removal system. Background Technology

[0002] In mine rock tunnels, drilling and blasting or mechanical methods are commonly used for rock breaking. TBM (Tunnel Boring Machine) construction is a type of mechanical method. TBM construction integrates multiple functions such as tunneling, muck removal, support, dust control, and guidance, enabling parallel operation of key processes like tunneling, support, and transportation. When the TBM passes through a fractured zone, the difficulty of simultaneous support operations leads to a large accumulation of fallen rock fragments at the bottom of the tunnel. This can severely impede the TBM's progress and delay construction, necessitating timely clearing of the accumulated rock fragments.

[0003] Currently, manual or specialized equipment is mostly used for muck removal in tunnels. Manual muck removal is inefficient, labor-intensive, and has a low safety factor. Furthermore, the narrow spaces in rock tunnels make it difficult for specialized equipment to enter and exit, hindering muck removal operations. Therefore, developing a combined TBM muck removal system is an urgent problem to be solved in order to improve the automation and integration of TBMs and achieve real-time muck removal during the TBM tunneling process. Summary of the Invention

[0004] The purpose of this invention is to provide a combined TBM (Tunnel Boring Machine) slag removal system. This novel TBM slag removal system can remove rubble accumulated at the bottom of the tunnel in real time during the TBM tunneling process.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a combined TBM tunneling machine slag removal system, comprising a side excavation translation cylinder seat, a side excavation slide seat, a side excavation translation cylinder, a side excavation slide frame, a side excavation swing arm, a swing cylinder, a bucket lifting cylinder, a side excavation bucket, a slag collection bucket base, a rotary motor, a slag collection bucket main frame, a lifting cylinder, a bucket connecting frame, a slag collection bucket, and a rear lifting cylinder.
