Operation principle of the present invention: under the external force effect of body weight, pass through between two rollers 4081 and 4082 of steel wire rope from targeting part 4, after bottom roller 4081 is stressed, driving U type support 405 moves down, U type support 405 moves down piston 404, enforce compression spring 403, thus guarantee that steel wire rope moves along the tangent to periphery direction of wheel hub 208 all the time; Because people's body weight difference, having apart from length that piston 404 moves is different, steel wire rope 602 drives wheel hub 208 rotations, principle by the running of freewheel clutch 210 single load bearings, 306 turns of driven gear axle, drive planetary gear 309 rotations by gear meshing, planetary gear 309 is installed in the internal gear 301, internal gear 301 is connected firmly on bracing frame 320 motionless, the rotation of planetary gear 309 drives planet carrier 316 rotations, by making the friction compounded plate enter duty behind the elementary reduction of speed of gear, drive the friction moving plate rotation of 318 li of speed stabilizing friction plate assemblies, rotation and still friction by moving plate produce frictional force, thereby reach the speed stabilizing purpose, make the personnel of saving oneself be able to safety in the air when jumping off, at the uniform velocity, drop to outdoor ground lentamente, after personnel are rescued, steel wire rope 602 rely on deadweight pass in the targeting part 4 two rollers 4081 and 4082 vertically upward automatically the machine of returning reset, the elastic force that compresses spring 403 this moment discharges, piston 404 moves up, and is steady when reclaiming to guarantee steel wire rope, safety.At this moment freewheel clutch 210 reverse zero loads are not turned round, wheel hub 208 and speed stabilizing friction plate assembly 318 are thrown off fully, be installed in this moment and begin to discharge after wheel hub 208 interior flexible strips 209 shrink when personnel descend by force, make the wheel hub 208 of coiling steel wire rope 602 go up cycle receipts steel wire rope 602 automatically counterclockwise, steel wire rope 602 is aligned in main frame wheel hub 208 wire casings rapidly by conductor rope part 5 again in an orderly manner, recover holding state, use successively for the personnel of saving oneself.
Using method of the present invention: it is standby that the present invention is fixed on the indoor window of building top, posts ease of Use figure, and extension of the present invention goes out one section steel wire rope and coupling hook, is convenient to the personnel of saving oneself and operates in the flooring.Every machine is furnished with 2-3 bar safety belt, and everyone uses a safety belt at every turn, must fasten one's safety belt, when dangerous situation takes place, the personnel that save oneself only need that safety belt is lain in waist degree of tightness appropriateness and get final product, and then the hook on the safety belt are connected steel wire rope of the present invention termination hook, have promptly finished whole operating process.Before window escape, should re-recognize two hooks of true inspection connect whether correct after, promptly can relieved outwards the escaping of various postures from window.Whole decline process is automatically fully, need not to save oneself personnel operation and control, and a need two is held tight two handgrips and is got final product.After the self-help escape personal security dropped to ground, the safety hook of should making the best use of time to remove was preferably directly unfastened one's seat-belt, and safety belt was together sent back to upstairs, to rescue more distress personnel with the steel wire rope hook.Safeguard protection when the present invention also can be used for the work high above the ground personnel and works.
The speed of the manned decline of the present invention is about 1 meter to 1.5 meters of per seconds, is particularly suitable for body weight personnel use more than 40 kilograms, and body weight is light more, and decrease speed is slow more; With 45 kg body weight actual measurement decrease speed is 1 meter per second, 50-60 kg body weight actual measurement decrease speed is 1.2 meter per seconds, 60-70 kg body weight actual measurement decrease speed is 1.3 meter per seconds, and 70-80 kg body weight actual measurement decrease speed is 1.4 meter per seconds, and body weight actual measurement decrease speed is 1.5 meter per seconds more than 90 kilograms.The present invention is not suitable for children and independently uses.
