Tunnel ventilation pipeline construction car

Abstract

The invention discloses a tunnel ventilation pipeline construction car, which comprises a walking trolley, a walking drive mechanism, a pipeline stretching and retracting device, an electric pipeline stretching and retracting drive mechanism and an electronic circuit board, wherein a winding shaft of the pipeline stretching and retracting device is continuously wound with flexible air pipes from inside to outside; the rear end part of each flexible air pipe is connected with an electric ventilator air supply outlet arranged at a construction tunnel opening; the front end part of each flexible air pipe is fixedly arranged on the walking trolley through a temporary fastening piece; the front end part of each flexible pipe is connected with an air outlet for feeding fresh air to a tunneling working face of the construction tunnel; the electronic circuit board is provided with a controller, a walking direction detection unit, a walking position detection unit, an air supply amount detection unit and a first wireless communication module. The tunnel ventilation pipeline construction car is simple in structure, reasonable in design, simple and convenient to operate, high in intelligent degree and good in use effect; and with the adoption of the tunnel ventilation pipeline construction car, the problems of high on-site workload, more manpower and material resources needed to be invested, inconvenient use operation and poorer ventilation effect and the like existing in a tunnel ventilation construction manner can be solved.

Description

technical field [0001] The invention belongs to the technical field of tunnel ventilation construction, in particular to a tunnel ventilation pipeline construction vehicle. Background technique [0002] As we all know, ventilation in tunnel construction is a key process. Its function is to deliver enough fresh air from outside the tunnel to the inside of the tunnel, and to discharge the gun smoke and harmful gases generated by blasting and transportation in the tunnel, so as to finally ensure the safety of the workers and machinery in the tunnel. The need for fresh air makes the air in the cave meet the standards stipulated by the state and industry. The quality of the ventilation effect in the construction of long tunnels directly affects the progress of the project and the health of the workers. At present, the tunnel construction ventilation at home and abroad mostly adopts the pipeline press-in ventilation method, and an axial flow fan is installed outside the tunnel en...
