Description

Guide rail for shield tunnel segment Technical Field The utility model relates to the technical field of tunnel segments, in particular to a guide rail for a shield tunnel segment. Background The tunnel segment is a concrete layer paved on the inner wall of the tunnel, and when the tunnel segment needs to be repaired, a layer of steel plate needs to be temporarily paved on the segment to serve as a support, so that broken segments are prevented from being damaged, and broken stones are prevented from being dropped. The existing steel plate is paved through the mechanical arm, but because the volume of the mechanical arm itself causes that a large amount of construction space is occupied in the tunnel, the movable space in the tunnel is reduced, and the movable construction is inconvenient for constructors. Disclosure of utility model The utility model aims to provide a guide rail for shield tunnel segments, which solves the problem that the movable space for constructors in a tunnel is reduced because the mechanical arm occupies too much tunnel space when the conventional segments are paved with steel plates. The utility model is realized by the following technical scheme: The utility model provides a guide rail for shield tunnel segments, which comprises a tunnel, wherein segment is arranged on the inner wall of the tunnel, connecting blocks are arranged on the inner wall of the segment, two groups of connecting blocks are arranged on the inner wall of the segment, hanging lugs are arranged at the tops of the connecting blocks, a chain block is connected to the middle of each hanging lug, connecting bearings are arranged at the tops of the connecting blocks, rolling shafts are connected between the connecting bearings, and a limiting component is arranged on one side of each connecting block. Preferably, the connecting block is connected to the duct piece through bolts, and the plurality of connecting blocks are arranged. Preferably, both ends of the roller are rotatably connected in the connecting bearing. Preferably, the limiting assembly comprises a deflection groove, a deflection rod and a limiting wheel, wherein the deflection groove is arranged on one side of the connecting block, the deflection rod is connected to the middle part of the deflection groove, and the limiting wheel is connected to one end of the deflection rod. Preferably, the deflection groove is arranged on one side opposite to the two connecting blocks, and two sides of the middle part of the deflection groove are obliquely arranged. Preferably, one end of the deflection rod is hinged in the middle of the deflection groove, and torsion springs are arranged at two ends of the hinge shaft at one end of the deflection rod.
