Multifunctional rope paying-off equipment

Abstract

The invention discloses multifunctional rope paying-off equipment. The multifunctional rope paying-off equipment comprises two or more sets of shell equipment. Each set of shell equipment comprises a shell, a motor, winding drums or rotating shafts and a descent control device. Each motor, the corresponding winding drums or rotating shafts and the corresponding descent control device are arranged in the corresponding shell. Each motor can drive the corresponding winding drums or rotating shafts to rotate. Each winding drum or rotating shaft is sleeved with a circular ring. Each circular ring can rotate around the corresponding winding drum or rotating shaft. Each circular ring is provided with a blocking face. Each winding drum or rotating shaft is provided with a blocking part. Each descent control device is arranged on the corresponding circular ring. After extending out of the corresponding descent control device and being wound on the corresponding winding drums or rotating shafts, slow descent ropes of each descent control device extend out of the corresponding winding drums or rotating shafts and are connected with weights. The multifunctional rope paying-off equipment is connected with a control cable with one section extending out of the shells and provided with a controller or connected with a section of control pull rope extending out of the shells.

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
