Multifunctional rope releasing equipment

Abstract

The invention relates to multifunctional rope releasing equipment. The multifunctional rope releasing equipment comprises a motor, a reel and a pull rope, wherein the motor is connected with the reeldirectly or by virtue of a transmission mechanism so as to drive the reel to rotate, a rotary ring body is connected to a reel shaft of the reel, the rotary ring body can rotate only in one directionand is locked in the other direction so as not to rotate, the pull rope is connected to the rotary ring body, the pull rope extends from the rotary ring body, then is wound on the reel, extends from the reel and then is directly connected with a heavy object or passes through a wire slot of an angle pulley and then is connected with the heavy object, the heavy object structurally comprises a rubber ball or a fixed pulley or a movable pulley, a cable which is connected with the motor extends outwards and is connected with a power supply by virtue of an electrical element which can be connectedwith or disconnected from the power supply, and the motor can be powered on and rotate clockwise or anticlockwise by using the electrical element.

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. In the event of a fire, the reliability of fire elevators is worth pondering. There are also existing fire trucks used for fire and rescue, which can generally implement fire fighting and rescue people at a height of 53 meters. , and there is a limit to the height of the fire-fighting aerial ladder truck. Usually, the fire-fighting aerial ladder truck can only rise to about 80% of the limit value. Once a high-rise building catches fire or people are trapped, it is difficult for the fire ladder to play a role. Generally, the trapped people can only rely on their own ability to escape, but some high-rise buildings have insufficient fire-fighting facilities, and the fire hydrant doors are blocked by residents with debris, etc. Vario...

[0002] Fires in high-rise buildings have always attracted people's attention. In the event of a fire, the reliability of fire elevators is worth pondering. There are also existing fire trucks used for fire and rescue, which can generally implement fire fighting and rescue people at a height of 53 meters. , and there is a limit to the height of the fire-fighting aerial ladder truck. Usually, the fire-fighting aerial ladder truck can only rise to about 80% of the limit value. Once a high-rise building catches fire or people are trapped, it is difficult for the fire ladder to play a role. Generally, the trapped people can only rely on their own ability to escape, but some high-rise buildings have insufficient fire-fighting facilities, and the fire hydrant doors are blocked by residents with debris, etc. Various phenomena bring resistance to fire extinguishing 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
