Multifunctional rope releasing equipment with rescue function

Abstract

The invention provides multifunctional rope releasing equipment with a rescue function. The multifunctional rope releasing equipment comprises a power transmission system or a hydraulic transmission system or a pneumatic transmission system, winding drums or rotating shafts, and a descent control device, wherein rotary shafts of a motor of the power transmission system or the hydraulic transmission system or the pneumatic transmission system can drive the winding drums or the rotating shafts to rotate; circular rings are arranged on the winding drums or the rotating shafts in a sleeving mode,and the circular rings can rotate around the winding drums or the rotating shafts; blocking surfaces are arranged on the circular rings, and blocking pieces are arranged on the winding drums or the rotating shafts; the descent control device is arranged on the corresponding circular ring, and descent control ropes of the descent control device extend out of the descent control device and are woundaround the winding drums or the rotating shafts; and a cable connected with the motor is connected with a power supply through a main contact of a contactor, a coil of the contactor is connected witha PLC and the power supply to form a loop, and a button or a touch screen connected with the PLC can control the main contact of the contactor to be closed and enable the motor to rotate forward or reversely.

Description

technical field [0001] This application belongs to an escape device. Background technique [0002] Fires in high-rise buildings 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. % or so, if the wind force on the ground reaches level 4 to 5, the fire-fighting aerial ladder truck will not be able to raise the operation. In this way, once a high-rise building above 50 meters catches fire or people are trapped, it will be difficult for the fire-fighting aerial ladder to play a role. Rely on one's own ability to escape, but some high-rise buildings have incomplete fire protection facilities, fire...

AI Technical Summary

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.
