Building with multifunctional rope unwinding device

Abstract

The invention provides a building with a multifunctional rope unwinding device. The building with the multifunctional rope unwinding device comprises the multifunctional rope unwinding device arrangedabove the building; the multifunctional rope unwinding device comprises an electric machine, coiling blocks and pulling ropes; the electric machine can drive the coiling blocks to rotate; the coilingblocks are sleeved with rings; the rings can rotate around the coiling blocks; the rings are provided with blocking faces; the coiling blocks are provided with blocking pieces; one end of each pulling rope is connected to the corresponding ring; after the pulling ropes extend out of the rings and are wound on the coiling blocks, the pulling ropes extend out of the coiling blocks and are directlyconnected with heavy objects or are connected with the heavy objects after penetrating wire grooves of direction changing pulleys; and the structure of each heavy object comprises a rubber ball or a fixed pulley or a movable pulley, and a cable connected with the electric machine extends outwards, and is connected with a power source above the building with the multifunctional rope unwinding device through an electric control system.

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. In the event of a fire, the reliability of fire elevators is worth pondering. There are also existing fire trucks used for fire and lifesaving, 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 incomplete fire-fighting facilities, and the fire hydrant doors are blocked by residents with sundries, etc. Various phenomena bring resista...

[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 incomplete fire-fighting facilities, and the fire hydrant doors are blocked by residents with sundries, 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 measures for fire extinguishing, rescue and escape outside the building
