Abstract :
A suspension tunnel rescue device is studied, which includes a guide rail installed on the top of the tunnel, and an operating system platform mounted on the bottom of the wheel. Advantages: firstly, the rescue platform can achieve a barrier-free movement as it is suspended on the guide rail. In the case of fire in the tunnel, the rescue platform can quickly reach the disaster location to avoid personal injury and property loss even if the tunnel is blocked; secondly, the rescue platform and fire extinction platform can be disassembled from each other, to provide a non-blocking working platform for inspection and maintenance in tunnel. In addition, an umbrella type combined nozzle which is composed of the auxiliary nozzle and the main nozzle was designed. The auxiliary nozzles spray water to isolate the fire while the distribution circumference of the subsidiary nozzles is adjustable.
