Abstract

The invention discloses an overhead escape device of a light rail. The device comprises an outer shell and an inner shell positioned in the outer shell, wherein an escape rope is arranged in the inner shell and two ends of the escape rope run through the same side of the outer shell and inner shell; a retarding mechanism is arranged in the inner shell and mainly comprises a round static friction block and two round kinetic friction blocks; the two movable friction blocks are symmetrically positioned on two sides of a centre line of the static friction block; the escape rope sequentially winds over one movable friction block, the static friction block and the other movable friction block; and the centre of the static friction block deviates for a certain distance from the connection line of the centres of the two movable friction blocks so that the escape rope forms a certain wrap angle with the kinetic friction blocks. The device has the advantages of low cost, convenient use, simple structure, reliable performance and convenient maintenance. The required time for the whole landing process is short and the device can be repeatedly and uninterruptedly used so that many people can conveniently and quickly escape.

Description

technical field

[0001] The invention relates to a high-altitude escape device, in particular to a high-altitude escape device for a light rail. Background technique

[0002] Escape from high altitudes (such as airplanes and high-rise buildings) is a worldwide problem. At present, there is no effective solution. The higher the altitude, the greater the difficulty. Because after a certain height, the outside rescue forces and equipment are out of reach, unable to reach directly, and can only rely on their own rescue equipment to save themselves. In addition, the situation in the event of a dangerous situation varies greatly, such as no power supply, inability to use rescue equipment that requires power supply, smoke disturbance, and difficult to determine the direction.

[0003] And there are also high-rise escape devices with low floors at present, and its types mainly contain angle-wrapping type, intermittent impact type and liquid damping type. The intermittent impact typ...
