Technical Field

[0001] This invention relates to the field of tunnel boring machine (TBM) technology, specifically to a TBM dismantling and transportation device within a tunnel. Background Technology

[0002] When tunneling a submarine drainage tunnel, since the drainage tunnel does not need to be fully connected, it is impossible to recover the machine through the vertical shafts at both ends of the tunnel. Therefore, the tunnel boring machine (TBM) needs to be disassembled inside the tunnel and transported back using transport vehicles to complete the TBM recovery operation. However, existing transport vehicles are inconvenient for limiting and fixing TBM components of different sizes. Furthermore, due to the slope of the tunnel, the weight of the TBM components makes it difficult for the transport vehicles to go uphill, which can easily lead to landslides.

This completes the synchronous rotation between the winding reel and the support shaft, facilitating the traction and pulling operation of the rope on one end of the transport platform on the transport track, improving the stability when going uphill, and preventing slippage. When the screw and screw groove are not connected, it does not affect the rotation of the winding reel on the support shaft, facilitating the winding operation of the rope.
