Building with multifunctional rope pay-off equipment

Abstract

Provided is a building with multifunctional rope pay-off equipment. The building with the multifunctional rope pay-off equipment comprises the multifunctional rope pay-off equipment arranged on a roof storey or a refuge storey or an upper storey of the building. The multifunctional rope pay-off equipment comprises an air pressure transmission system, reeling barrels or rotating shafts and a slow descending device. The air pressure transmission system comprises a pneumatic motor which can drive the reeling barrels or the rotating shafts to rotate through a transmission mechanism. The reeling barrels or the rotating shafts are sleeved with circular rings which can rotate around the reeling barrels or the rotating shafts. Blocking faces are arranged on the circular rings, and blocking members are arranged on the reeling barrels or the rotating shafts. The slow descending device is arranged on the circular rings. After slow descending ropes of the slow descending device extend out from the slow descending device and are wound around the reeling barrels or the rotating shafts, the slow descending ropes extend out from the reeling barrels or the rotating shafts and are connected with heavy items. The multifunctional rope pay-off equipment is connected with a section of controlling cable or a section of controlling pulling rope. The controlling cable or the controlling pulling rope extends downwards or out of the building for use.

Description

technical field [0001] The application belongs to a building with functions of fire extinguishing, rescue and escape. Background technique [0002] Fires in high-rise buildings have always attracted people's attention, and the reliability of fire elevators in the event of a fire is worth pondering. There is also the arm-raising fire truck used in the existing fire-fighting and lifesaving, which can generally implement fire fighting and rescue at a height of 53 meters, and the climbing of the fire-fighting ladder truck has a limit. Usually, the fire-fighting ladder truck can only rise to 80 of the limit value. % or so, if the wind force on the ground reaches level 4 to 5, the fire-fighting aerial ladder truck will not be able to raise the operation. In this way, once a high-rise building above 50 meters catches fire or people are trapped, it will be difficult for the fire-fighting aerial ladder to play a role.

Problems solved by technology

There is also the arm-raising fire truck used in the existing fire-fighting and lifesaving, which can generally implement fire fighting and rescue at a height of 53 meters, and the climbing of the fire-fighting ladder truck has a limit. Usually, the fire-fighting ladder truck can only rise to 80 of the limit value. % or so, if the wind force on the ground reaches level 4 to 5, the fire-fighting aerial ladder truck will not be able to raise the operation. In this way, once a high-rise building above 50 meters catches fire or people are trapped, it will be difficult for the fire-fighting aerial ladder to play a role. Rely on one's own ability to escape, but some high-rise buildings have incomplete fire-fighting facilities, fire hydrant doors are blocked by residents with sundries and other phenomena, which bring resistance to fire-fighting and escape

In short, when the height of the ladder truck is not enough, the fire rescue personnel are fully armed and go up the fire floor from the stairs to carry out fire fighting and rescue, which seriously affects the speed and efficiency of rescue and fire fighting. The existing technology has appeared on the roof layer or refuge floor of the building. Set up the rope-releasing equipment. In the event of a fire, the above-mentioned rope-releasing equipment can be controlled to lower the slow-down rope and pull rope for emergency escape. However, the technical solution of the rope-releasing technique has certain safety risks, and also has the disadvantages of relatively complex structure and high cost. It has become necessary to study reliable and safe measures for fire extinguishing, rescue and escape outside the building
