Principle of the present utility model is: during slow falling, rotary handle, what be connected with handle is the threaded spring-advance axle of cylindrical, between spring-advance axle and the left frame board with being threaded, therefore the spring-advance axle can move thereupon inwards or outwards during rotary handle, directly pressing the spring-advance sheet owing to the spring-advance axle again, so the spring-advance sheet can move inwards or outwards thereupon also.Because spring is in compressive state all the time, therefore two friction plates are close to all the time, between two friction plates normal pressure are arranged, and therefore can produce the moment of resistance that frictional force causes between two friction plates.Friction plate II is fixedlyed connected with last axle, this moment of resistance can make the axle rotating speed reduce, make the flywheel rotating speed of fixedlying connected change with last axle, the corresponding reduction of chain wheel speed that couples together by chain with flywheel, cause reducing with the reel rotating speed of sprocket coaxiality, be that payingoff speed slows down, make descending lifeline be able to slow decline.

During answer, drive sun gear I in the lower shaft rotary course and rotate with identical speed, the planetary gear of Pei Heing is also along with the sun gear rotation with it, and planetary gear drives the clockwork spring lid by sprocket and rotates, clockwork spring is winded up, make that the clockwork spring power of winding up constantly increases in the decline process.If descending lifeline falls with the people, then when descending lifeline falls, descending lifeline drops to ground, lower shaft stops the rotation, at this moment, because clockwork spring produces very big moment loading, and this moment can make the lower shaft reverse rotation much larger than the moment that the descending lifeline self gravitation produces, during the lower shaft counter-rotating, the counter-rotating of drive sprocket wheel, sprocket wheel drives the flywheel counter-rotating by chain, because there is ratchet structure flywheel inside, going up axle when therefore flywheel reverses can't reverse thereupon, be friction plate this moment and inoperative, thus, descending lifeline is returned initial position; If descending lifeline is fixed, the people is along with rope descends, and then rope returns and is recovered to original position very soon.

The beneficial effects of the utility model are; 1, the principle of brake block is applied to descending lifeline and reach slow purpose of falling, greatly guarantee decline process safe and reliability; 2, owing to used the combination of planetary gear and clockwork spring, therefore can repeatedly recycle, a device can be rescued many people, and because clockwork spring has quick recovery, but assurance device can set back rapidly after once using; 3, because the utilization of groups of springs, can be in the decline process, the decrement by regulating spring changes the speed of putting rope, promptly changes the speed that the people descends, and adjustment process is simple, and is reliable and guaranteed; 4, this device can be applied to any floor use, and operating process is grasped easily; 5, can change the passive situation that in the past can only rely on fire-fighting and rescue, for captive provides a kind of selectable apparatus of escaping danger.
