Multifunctional rope unwinding equipment

Abstract

The invention discloses multifunctional rope unwinding equipment. The multifunctional rope unwinding equipment comprises motors, rotating bodies and descent control devices; each motor is connected with the corresponding rotating body directly or through a transmission mechanism; each rotating body is connected with a ratchet wheel mechanism; each descent control device is arranged on the corresponding rotating body; descent control ropes of the descent control devices wind the rotating bodies or wind winding drums or winding shafts after extending out from the rotating bodies, and extend outfrom the rotating bodies or the winding drums or the winding shafts; cables which are connected with the motors extend outwards and are connected with the power supply through electrical apparatus elements which can be switched on or switched off; and the electrical apparatus elements can switch on or switch off the power of the motors and enable the motors to rotate forward or backward.

Description

technical field [0001] The application belongs to a kind of outdoor fire extinguishing, rescue and escape equipment used in the field of buildings. 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, so 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...

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, so 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 fire extinguishing, rescue and escape equipment outside the building
