Building or structure with multifunctional unwinding device

Abstract

The invention provides a building or structure with a multifunctional unwinding device. The multifunctional unwinding device is arranged on a roof of the building, and the multifunctional rope unwinding device comprises a power transmission system or a hydraulic transmission system or a pneumatic transmission system, a winding drum and a descent control device; a rotating shaft of a motor of the power transmission system or the hydraulic transmission system or the pneumatic transmission system can drive the winding drum to rotate through a transmission mechanism; a circular ring sleeves the winding drum, the circular ring can rotate around the winding drum, a blocking surface is arranged on the circular ring, and a blocking part is arranged on the winding drum or the rotating shaft; the descent control device is arranged on the circular ring, and after extending out of the descent control device and wound on the winding drum, a descent control rope of the descent control device is connected with a weight; and a cable connected with an electric motor or the motor or an electromagnetic reversing valve extends downwards to be below or outside the building or structure and is connectedwith a power supply through an electrical control system.

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.
