Split starting pipeline extending device of shield tunneling machine

The utility model discloses a split starting pipeline extending device of a shield tunneling machine. Including a base, two symmetrically-arranged supports are installed at the top end of the base. Two baffles which are symmetrically arranged are rotatably connected between the two brackets; a winding roller is connected between the two baffles; one side of one baffle is connected with a rotatingshaft; the end part of the rotating shaft penetrates through the bracket and is connected with a driven wheel; a rotating motor is installed at the top end of the base through screws, a driving wheelis connected to an output shaft of the rotating motor, two symmetrically-arranged sliding grooves are formed in the top end of the base, sliding blocks are slidably connected into the sliding grooves,and pressure sensors are installed at the ends, away from the support, of the sliding grooves of the base. The pipeline fixing device is novel in structure, simple in pipeline arrangement, easy to operate, low in disassembly a
