Multifunctional rope releasing device

Abstract

The invention relates to a multifunctional rope releasing device. The multifunctional rope releasing device comprises an electric transmission system or a hydraulic transmission system or an air pressure transmission system, a winding drum or a rotary shaft, and a descent control device, wherein a rotating shaft of a motor of the electric transmission system or the hydraulic transmission system orthe air pressure transmission system can drive the winding drum or the rotary shaft to rotate through a transmission mechanism, a circular ring is arranged on the winding drum or the rotary shaft ina sleeving mode, the circular ring can rotate around the winding drum or the rotary shaft, the descent control device is arranged on the circular ring, a descent control rope of the descent control device extends out of the descent control device, is wound around the winding drum or the rotary shaft and then extends out of the winding drum or the rotary shaft, and a cable connected with a motor extends out and is connected with a power supply through an electrical element capable of connecting or disconnecting the power supply. By using the electrical element, the motor can be powered on and rotates forward or reversely, and the motor can rotate forward or reversely to drive the descent control rope to rotationally extend out from the winding drum or the rotary shaft to be hung on the descent control device in a pulled mode.

Description

technical field [0001] The application belongs to a kind of outdoor fire extinguishing, rescue and escape equipment used in the field of buildings. Background technique [0002] The world's second tallest tower, the 540-meter-high Ostankino TV Tower in Russia, suffered a fire, which caused all major Russian TV stations to stop broadcasting. Communications between all paging stations in Moscow, the Ministry of Internal Affairs, and the Moscow emergency system were interrupted. Four people were trapped in the elevator. Death, many people were injured, the structure of the TV tower was seriously damaged, shocking the world, the fire of high-rise buildings has always attracted people's attention, but the reliability of fire elevators in the event of a fire is more worthy of consideration. 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 ...

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.
