Rope paying-off device with fire extinguishment and rescue functions

Abstract

A rope paying-off device with fire extinguishment and rescue functions comprises an electric rope coiling device and a cantilever, wherein the cantilever is provided with a pulley; the electric rope coiling device comprises a rope coiling barrel; a rope penetrates through internal holes of the rope coiling barrel and extends out of the rope coiling barrel to form a pulling rope I and a pulling rope II; the pulling rope I and the pulling rope II extend out of the internal holes in the two ends of the rope coiling barrel, are coiled by multiple turns on the rope coiling barrel towards the same direction, extend on the rope coiling barrel, wind across the pulley on the cantilever and then are coiled on the rope coiling barrel or coiled into coils or folded into bunches, and the pulling rope I and the pulling rope II can fall downwards and extend to be hung on the internal holes of the rope coiling barrel in a sliding mode.

Description

technical field [0001] The application belongs to a fire extinguishing and rescue equipment for buildings or structures. Background technique [0002] Fires in high-rise buildings have always drawn people's attention. The existing fire-fighting and lifesaving fire trucks can generally carry out fire fighting and rescue at a height of 53 meters, which is equivalent to a height of 15 floors. When a fire breaks out in a high-rise, in addition to walking upstairs with water to put out the fire, more often the fire officers and soldiers can only look at the "fire" and sigh, let alone go upstairs to save people. There is a limit to the height of the fire-fighting aerial ladder vehicle. Usually, the fire-fighting aerial ladder vehicle can only rise to about 80% of the limit value. If the ground wind reaches level 4 to 5, the fire-fighting aerial ladder vehicle will not be able to rise to work. Once a high-rise building above 50 meters catches fire or people are trapped, it is diff...
