Multifunctional rope release device with rescue function

Abstract

The invention provides a multifunctional rope release device with a rescue function. The multifunctional rope release device comprises an electric transmission system or a hydraulic transmission system or a pneumatic transmission system, winding drums or rotating shafts and pull ropes. A rotation shaft of a motor of the electric transmission system or the hydraulic transmission system or the pneumatic transmission system can drive the winding drums or the rotating shafts to rotate. Each winding drum or rotating shaft is sleeved with a circular ring. The circular rings can rotate around the winding drums or the rotating shafts. A blocking face is arranged on each circular ring. A blocking piece is arranged on each winding drum or rotating shaft. One end of each pull rope mentioned above isconnected to the corresponding circular ring. The pull ropes mentioned above extend out from the corresponding circular ring, are wound around the corresponding winding drums or the corresponding rotating shaft and then extend out from the corresponding winding drums or the corresponding rotating shaft. Cables connected with the electric motor are connected with a power supply through a main contact of a contactor. A loop is formed by coils of the contactor mentioned above, a PLC and the power supply.

Description

technical field [0001] The application belongs to an escape device. 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, but some high-rise buildings have incomplete fire protection facilities, fire ...

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
