Multifunctional rope unwinding equipment

Abstract

The invention discloses a building with multifunctional rope unwinding equipment. The building with the multifunctional rope unwinding equipment comprises the multifunctional rope unwinding equipment arranged on a roof layer or a refuge floor or an upper floor of the building; the multifunctional rope unwinding equipment comprises a power transmission system or a hydraulic transmission system or an air pressure transmission system, a rotating body and a descent control device; a rotating shaft of a motor of the power transmission system or the hydraulic transmission system or the air pressure transmission system is connected with the rotating body directly or through a transmission mechanism; a ratchet mechanism is arranged on the rotating shaft or the transmission mechanism or the rotating body; the descent control device is arranged on the rotating body; a slow descent rope of the descent control device is wound on the rotating body or a winding drum or a winding shaft and extends out from the rotating body or the winding drum or the winding shaft after extending from the descent control device; a remote controller is used below or outside the building for controlling the motor to drive the slow descent rope to rotate to extend out; and the slow descent rope is hung on the descent control device after rotating extension.

Description

technical field [0001] The application belongs to a kind of outdoor fire extinguishing, rescue and escape equipment used in the construction field. 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. Rely on one's own ability to escape...

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 a word, 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 rope-releasing equipment. In case of 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 fire extinguishing, rescue and escape equipment outside the building
