Problems solved by technology

The space in the tunnel is small, and there are many risk factors, inconvenient operation, long working time and other unfavorable factors in changing the span and structure of the tunnel track-laying machine in the tunnel. Once the tunnel track-laying machine in the tunnel is stopped, the entire track paving process will be stagnant , causing idle work
In the existing te

Abstract

The invention discloses a tunnel track laying machine and a hydraulic cylinder support arm for the track laying machine, and comprises a tunnel track laying machine and a hydraulic cylinder support arm for assisting the track laying machine. The tunnel track laying machine comprises lower end beams which are horizontally arranged at intervals, walking mechanisms are arranged at the bottom ends ofthe two ends of the lower end beams correspondingly, supporting legs which are vertically arranged are fixed to the top ends of the end parts of the lower end beams, and the top ends of the support legs are fixedly provided with upper end beams parallel to the lower end beams; and a main beam of the track laying machine is arranged between every two upper end beams, the two ends of the main beamsare fixed to the upper ends of the upper end beams correspondingly, the bottom ends of the main beams are fixed to support beams which are arranged in parallel at intervals, and the main beams are provided with lifting mechanisms. The hydraulic cylinder support arm comprises a rectangular chassis, lower support arms are arranged at the four corners of the top end of the chassis, hydraulic cylinders are arranged in the lower support arms, the hydraulic cylinders are hinged to the bottom ends of the lower support arms, and the free ends of the hydraulic cylinders are hinged to the bottom ends ofupper support arms. The tunnel track laying machine and the hydraulic cylinder support arm for the track laying machine are simple in structure and convenient to operate, and the working efficiency of tunnel laying is improved.
