Suspension tunnel disaster prevention rescue and maintenance device

Abstract

The invention discloses a hanging type tunnel disaster prevention, rescue and maintenance device which comprises a guide rail and a platform, wherein the guide rail is mounted at the top of a tunnel, and the platform is hung under a wheel and advances in the tunnel along with the wheel. The hanging type tunnel disaster prevention, rescue and maintenance device has the advantages that the guide rail is mounted at the top of the tunnel, the platform used for rescue advances along the guide rail in a hanging manner and is positioned in the air in the tunnel, and therefore the platform realizes barrier-free movement; under the situation that a fire occurs in the tunnel, even if the tunnel is blocked, the platform can also quickly reach a position waiting for rescue, personal injury and property damage are avoided, and meanwhile traffic non-blocking type daily maintenance in the tunnel can also be carried out. In addition, the invention designs an umbrella type combined nozzle which is composed of auxiliary nozzles and a main nozzle. The auxiliary nozzles spray water to isolate a fire site from the surroundings, the size of the distribution circle of the auxiliary nozzles can be adjusted, the main nozzle at the center can selectively spray gas, foam water and fire fighting water according to the fire characteristics, and therefore high-efficiency fire fighting can be realized.

Description

technical field [0001] The invention relates to a tunnel rescue device, in particular to a suspended tunnel rescue device. Background technique [0002] Traffic tunnels bring convenience to people's production and life, and while they are being used more and more, fires, which are major disasters, also occur frequently. Tunnel fires have the characteristics of complex and changeable fire causes, high smoke concentration, high temperature, easy and rapid fire spread, extremely difficult evacuation, and difficult fire fighting and rescue. Due to the closed environment of the traffic tunnel, the conditions for smoke exhaust and heat dissipation are poor during fire , the temperature is high, and high-concentration toxic fumes will be produced quickly, making it difficult to evacuate personnel, difficult to fight fires, and serious damage. In the event of a fire or car accident in a tunnel, the rapid arrival of professionals and the timely delivery of the wounded are particular...

Tunnel fires have the characteristics of complex and changeable fire causes, high smoke concentration, high temperature, easy and rapid fire spread, extremely difficult evacuation, and difficult fire fighting and rescue. Due to the closed environment of the traffic tunnel, the conditions for smoke exhaust and heat dissipation are poor during fire , the temperature is high, and high-concentration toxic fumes will be produced quickly, making it difficult to evacuate personnel, difficult to fight fires, and serious damage

In the event of a fire or car accident in a tunnel, the rapid arrival of professionals and the timely delivery of the wounded are particularly important. Past tunnel fire accidents have shown that when various fire rescue vehicles perform rescue tasks, they are usually unable to do so due to blocked passages or excessive fire. Timely enter a confined space like a tunnel for effective rescue, and the wounded cannot be rushed out within the golden time, so that the radiant heat of the fire or the secondary traffic accident will cause secondary injuries to the personnel

[0003] CN102838044B discloses a tunnel rescue crane, which rescues the rescue position through the crane arm and the lifting trolley on the machine arm. Although the machine arm and the lifting trolley can extend into the tunnel in the air, the locomotive of the crane still needs to Traveling to the appropriate position in the tunnel, there is still a tunnel blockage and the crane cannot reach the rescue position
