Description

A kind of high-rise life saving slow descending device

Technical field:

The utility model relates to mechanical control field, specifically a kind of high-rise life saving slow descending device.

Background technology:

As everyone knows, nowadays skyscraper is more and more, the floor building is more and more higher, and complex structure, personnel are intensive, various modernization settings and combustible material are also many, owing to be not equipped with escape and rescue equipment in the general building, in case so disasters such as breaking out of fire or earthquake, people can only evacuate escape from passway for escaping usually, yet in the escape process, people are often nervous, are prone to crowded, collision in the fire escape, phenomenon such as trample mutually, not only influence evacuation but also cause the fortuitous casualty accident easily.Under flurried situation, walk for a long time in the stair road, most people also are short of physical strength easily, for this reason, people have invented some and have been used for the slow rescue aid that falls of high-rise life saving, and this kind equipment mainly contains electromagnetic damping formula, frictional damping formula, impact damping formula by the damping principle branch.Wherein, the most volume of electromagnetic damping formula is bigger, equipment dependability is not high under the high-temperature condition, and frictional damping formula descending lifeline is owing to be subjected to the influence of heat fade, unstable properties when using continuously, and rope easy to wear and other components and parts, service life of equipment is shorter, as for impact damping formula descending lifeline, then more exist vibration strongly, easily block, shortcoming that security is not high.In addition, existing descending lifeline in use needs manually to control decrease speed mostly, and operation is had relatively high expectations, and causes operate miss to be caused danger thereby people are easily panic under emergency situation, and these equipment are not easy to old man and children's use of family; A lot of escape apparatus only are fit to single single escape to be used, and in the time interval that perhaps exists equipment to reclaim, rescue efficiency is lower.

Summary of the invention:

The utility model is for overcoming the deficiencies in the prior art, proposes a kind of compact conformation, smooth decreasing, do not need to practise in advance, high-efficiency reliable high-rise life saving slow descending device.

The technical measures that the utility model adopts are:

A kind of high-rise life saving slow descending device, comprise cylinder, two double-piston hydraulic cylinders, center bearing bracket, left plate, right plate, cross bar, choke valve, hydraulic oil pipe, deep groove ball bearing, steel wire rope, the folder becket bridle, bolt, it is characterized in that center bearing bracket comprises left socle and right support, left socle and right support screw mutually by internal and external threads and are one, cylinder is installed in the center bearing bracket middle part by deep groove ball bearing and can freely rotates around center bearing bracket, the cylinder two ends are provided with the convex race of the 45 ° of phase places that stagger each other, two double-piston hydraulic cylinders are positioned at cylinder interior, and be separately fixed on left plate and the right plate by left socle and right support, keep two double-piston hydraulic cylinder axis to be parallel to each other simultaneously, two double-piston hydraulic cylinders middle part is connected to form closed circuit by hydraulic oil pipe and choke valve, biside plate top connects by cross bar, the cylinder middle part is provided with the wiring groove, steel wire rope is wrapped in some circles in the wiring groove, the steel wire rope outside is pressed on groove surfaces by the folder becket bridle, and the two ends of steel wire rope are equipped with coupling hook.

Folder becket bridle in the utility model is to be formed by connecting by two semicircular ring and spring, loose-leaf.

When the utility model uses the survivor, the coupling hook of steel wire rope one end is connected on one's body safety belt, jump out building and begin escape, thereby the pulling steel wire rope drives the cam ring cylinder and rotates, and push the piston at one of them hydraulic cylinder A two ends, hydraulic oil is entered in another hydraulic cylinder B by hydraulic oil pipe and choke valve, after cylinder turns over 45 °, two pistons of cam ring squeezed fluid cylinder pressure B, make hydraulic oil flow back to hydraulic cylinder A by hydraulic oil pipe and choke valve once more, above process is repeated for 45 ° in every interval.Thereby throttle valve control makes hydraulic oil produce high pressure by the flow of valve port, and react on the cam ring cylinder by hydraulic cylinder piston and produce tangential component, stop the acceleration of cam cylinder to rotate trend, thereby form stable damping action, the cam ring cylinder is slowly rotated evenly discharge steel wire rope, realize that the survivor falls so that safety speed is slow.

The utility model utilizes cam ring the circumferential rotation of cylinder to be converted into the linear reciprocating motion of hydraulic cylinder piston, compact overall structure, volume is less, utilize choke valve that the control action of flow is guaranteed that damping action is stable simultaneously, automatically the survivor who adapts to different weight, removed the instant adjusting in using from, need not to practise in advance just can using, simple to operate, dependable performance, the survivor can be used alternatingly the two ends of steel wire rope in addition, realizes continuous unremitting escape, improved rescue efficiency, also have simple in structure, produce in enormous quantities with low cost, remarkable advantage such as device long service life etc.
