Building provided with multifunctional rope releasing equipment

Abstract

The invention discloses a building provided with multifunctional rope releasing equipment. The multifunctional rope releasing equipment comprises a motor, winding drums / rotary shafts, and a slow descending device; the motor is connected with the winding drums or the rotary shafts and can drive the winding drums or the rotary shafts to rotate; winding drum shafts of the winding drums or the rotary shafts are connected with rotating ring bodies; the rotating ring bodies simply can rotate in one direction, and are locked in the other direction and thus cannot rotate; the slow descending deviceis arranged on the rotating ring bodies; slow descending ropes extending out of the slow descending device are wound on the winding drums or the rotary shafts and extend out of the winding drums or the rotary shafts to be directly connected with heavy objects or to be connected with the heavy objects after penetrating through rope grooves of turning pulleys; a cable connected with the motor extends outwards and is connected with a power supply through main contacts of contactors above the building with the multifunctional rope releasing equipment; and coils of the contactors are connected witha PLC and the power supply for forming a return circuit.

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. Rely on one's own ability to escape, but some high-rise buildings...

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
