Building or structure with multifunctional reel-off equipment

Abstract

The invention relates to a building or a structure with multifunctional reel-off equipment. The multifunctional reel-off equipment is arranged on a roof of the building. The multifunctional reel-off equipment comprises a power transmission system or a hydraulic transmission system or a pneumatic transmissions system, coiling blocks or rotary shafts and descent control devices. A rotating shaft ofa motor of the power transmission system or the hydraulic transmission system or the pneumatic transmissions system is connected to the coiling blocks or the rotary shafts, a rotating ring is connected to a coiling block shaft of each coiling block or each rotary shaft, the rotating rings only can rotate in one direction and cannot rotate as being locked in another direction, the descent control devices are arranged on the rotating rings, slow descend ropes stretching from the descend control devices are wound on the coiling blocks or the rotary shafts, cables connected to an electric motor stretch downward to the lower side of the building or out of the building to be connected to a power supply through main contacts of contactors, and a coil of each contactor, a PLC and the power supplyare connected to form a circuit.

Description

technical field [0001] The application belongs to a building or structure with functions of fire extinguishing, rescue and escape. Background technique [0002] Fires in high-rise buildings or structures 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. %, if the wind 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 or structure above 50 meters catches fire or people are trapped, it will be difficult for the fire-fighting aerial ladder to function. You can only rely on your own ability to escape, a...

Problems solved by technology

[0022] After studying the use process of the above-mentioned existing descending device and the user's feelings, it is found that the existing descending device with the descending rope has many shortcomings: this descending device is provided on the floor of the fire place to provide This floor is used by escape personnel, because this floor is the ignition point of fire, which is a threat to the descending device suspended on this floor, and the existing descending device needs to be inspected regularly. Generally, individual buyers lack this awareness due to troubles, which also poses a threat to The normal use of the descending device has caused potential hidden dangers, and there have been casualty accidents using the descending device; the descending height of the existing descending devices with descending ropes is controlled below 100 meters. The volume and weight of the descending device is large, and it is difficult for individual users to hang it on the window, and the descending rope with a length of more than 100 meters is large in size and weight. It is not only difficult for the user to throw such a descending rope downward, but also because Due to the tail effect, the dropped slow-down rope will also accidentally injure the people under the building or the glass of the outer wall. At the same time, the weight and impact of the dropped slow-down rope will also cause damage to the internal structure of the slow-down device.

Moreover, many existing escape products and escape rescue programs have caused many adverse effects on the original building, such as occupying the area of ​​the building or occupying the distance between buildings, or having a great impact on the structure of the original building, etc.
