Damping drum device and ball damping tall-building escape apparatus with same

Abstract

The invention relates to a damping drum device and a ball damping tall-building escape apparatus with same. The damping drum device comprises a base plate and a rope drum and is characterized in that the base plate is connected with a center shaft vertically; the rope drum is sleeved on the center shaft; the rope drum is matched with the center shaft through a bearing; at least two channels for the radial reciprocating movement of balls are uniformly distributed on the matching surface of the base plate and the rope drum; and at least two arched channels which are connected to a circle in radial direction are separately and uniformly distributed on the adjacent end faces of the rope drum and the base plate along the circumference. By using the invention, damping can be generated in the process when a worker goes down from the tall-building and the deceleration effect can be realized; and the damping principle of the mechanism is that when sliding in the cross channels, balls are hampered to generate damping. The device has low friction and is reliable; and the entire device has the advantages that the device has small volume and light weight, is easy to carry, the speed can be regulated, etc.

Description

technical field [0001] The invention relates to a roller device with damping and a ball damping high-rise escape device thereof. The ball-damping high-rise escape device of the present invention is especially suitable for escaping and self-rescue in the sudden danger of high-rise buildings. Background technique [0002] In recent years, with the rapid economic development, housing construction has gradually become high-rise. In addition to hotels, shopping malls, and office buildings, residential buildings are also continuous high-rise buildings. Once a fire accident occurs, due to the densely populated, complex structure of high-rise buildings, narrow corridors, poor access and even imperfect fire protection facilities, there will be serious fire hazards. In the event of a sudden fire, it is a very difficult problem to save the lives of people upstairs. At present, ladders or ropes are mostly used for life-saving methods, because people will be nervous and dizzy when a fir...

AI Technical Summary

Problems solved by technology

At present, there are many slow-down devices, but there are problems respectively, which can be divided into two categories: (1) complex structure, many parts, labor-intensive and time-consuming manufacturing, more materials, and high cost

(2) The descent process requires manual operation, and cannot be used continuously, the descent speed is unstable, and the safety factor is low

The above-mentioned life preservers also have a common problem: they are large in size, occupy too much effective space no matter they are installed indoors or outdoors, and are unsightly

Therefore, it is difficult to promote the use of existing descending devices at present
