The TBM tunnel lining precast block installation device according to claim 3, wherein the hoisting mechanism comprises a hoisting frame moving along the support beam through a roller, a scroll for winding and unwinding a steel wire rope, a translation motor for driving the roller to rotate, a rotation motor for driving the scroll to rotate so as to realize winding and unwinding of the steel wire rope, and a clamp assembly installed at the other end of the steel wire rope;
the clamp assembly comprises a clamp body connected with the steel wire rope, a rotating disc installed at the bottom of the clamp body, a clamp installed on the rotating disc and corresponding to a precast block hoisting point, and a rotating motor driving the rotating disc to rotate transversely.
10. A method for constructing a tunnel lining of a TBM, which is carried out based on the installation apparatus of a precast block at the bottom of a tunnel according to claim 1, comprising the steps of:
(1) Removing front steel rails influencing the installation of the precast blocks in the installation area, and conveying sludge at the bottom of the tunnel in the installation area to a TBM continuous belt through a slag removing mechanism to be conveyed out of the tunnel;
(2) The prefabricated block transport vehicle transports the prefabricated block to be installed to the central track, the hoisting mechanism hoists the prefabricated block, and the transport vehicle drives away from the main beam frame;
(3) The horizontal moving oil cylinder horizontally moves the central track to one side of the main beam frame, the hoisting mechanism lowers the prefabricated block and adjusts the orientation of the prefabricated block, and the prefabricated block is installed in an area to be installed;
(4) Filling concrete between the prefabricated blocks after installation to ensure the connection and fastening of the prefabricated blocks, and paving steel rails on the newly installed prefabricated blocks;
(5) The prefabricated block which is installed is supported by the driving oil cylinder top to drive the whole device to move forwards so as to carry out the next installation.
