Multifunctional rope unwinding device

Abstract

Provided is a multifunctional rope unwinding device. The multifunctional rope unwinding device comprises an electric power transmission system or a hydraulic transmission system or a pneumatic transmission system, a coiling block or a rotating shaft, and a slow descending device; a rotating shaft of a motor of the electric power transmission system or the hydraulic transmission system or the pneumatic transmission system is used for driving the coiling block or the rotating shaft to rotate directly or through a transmission mechanism; a rotating ring body is connected to a coiling block shaftof the coiling block or the rotating shaft, and can only rotate in one direction and is locked in the other direction and cannot rotate; the slow descending device is arranged on the rotating ring body; a slow descending rope extending out of the slow descending device is wound on the coiling block or the rotating shaft and extends out of the coiling block or the rotating shaft; a cable connectedwith an electromotor downwards extends to the position below or outside a building, and is connected with a power source through a main contact point of a contactor; and a coil of the contactor is connected with a PLC and the power source to form a loop.

Description

Technical field [0001] The application belongs to an outdoor fire-fighting, rescue, and escape equipment used in the construction field. Background technique [0002] Fires in high-rise buildings have been drawing people's attention. The reliability of fire elevators in the event of a fire is worth pondering. There is also the existing fire-fighting and life-saving fire trucks, which can generally be used for fire fighting and rescue at a height of 53 meters, and there is a limit to the height of the fire-fighting ladder truck. Generally, the fire-fighting ladder truck can only be raised to a limit of 80 %. If the ground wind reaches level 4 to 5, the fire-fighting ladder truck will not be able to raise the operation. In this way, once a high-rise building above 50 meters is on fire or someone is trapped, the fire-fighting ladder will be difficult to function. Generally, the trapped personnel can only Relying on their own ability to escape, and some high-rise buildings have inco...

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.
