Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail.
As shown in Figure 1 and Figure 2, the present invention proposes a kind of life-saving high-altitude slow-falling device 100, it comprises housing 101, planetary speed increaser 102, bearing wheels 103, damping impeller 104, impeller chimney 105 and a reciprocal rope 106.Housing 101 comprises procapsid 1011 and the back casing 1012 being fixed to one another connection.Planetary speed increaser 102 runs through and is fixedly connected on procapsid 1011, and its power shaft is rotationally connected with back casing 1012 by a bearing 107, and output shaft is fixedly connected with the core retainer plate of damping impeller 104.The front side of bearing wheels 103 is rotationally connected with procapsid 1011 by a bearing 108, and meanwhile, bearing wheels 103 is fixedly connected with by the power shaft of core retainer plate with planetary speed increaser 102.Impeller chimney 105 covers damping impeller 104 and is fixedly connected on the front side of procapsid 1011.Arrange a rope outlet in the bottom of housing 101, between rope outlet and bearing wheels 103, interval arranges two sheaves 109, and each sheave 109 is all rotationally connected with housing 101.The winding of reciprocal rope 106 is in bearing wheels 103, and its two ends are drawn from rope outlet by sheave 109.At the two ends of reciprocal rope 106, a safety hook 110 is set respectively.Planetary speed increaser 102 in above-described embodiment also can replace to the speed increaser of other type.
Further, as shown in Figure 3, Figure 4, bearing wheels 103 is provided with the V-shaped cannelure in a cross section along wheel rim, for accommodating reciprocal rope 106.Further, in order to prevent skidding during reciprocal rope 106 load-bearing, the sidewall of cannelure is provided with damping asperities.
Further, connect a safety hook at the top of housing 101, for high-altitude slow-falling device 100 of the present invention being suspended on the weight-bearing surface of building.
When life-saving high-altitude slow-falling device 100 of the present invention is applied, (be preferably and hang) should be fixed on the weight-bearing surface of building, escape personnel can by the loins of one end of the reciprocal rope 106 on it wrapped around oneself, then health shifts out building, gravity is utilized to decline, due to the present invention's employing is air damping operation principle, and while escape personnel declines, damping impeller 104 high-speed rotary transfers to produce air damping acting, realizes the slow of escape personnel and falls.Further, in this process, the present invention, without any wearing and tearing, can not be lost efficacy, safety and stability.In addition, the present invention can for many people repeatedly continuously, namely when one end of reciprocal rope 106 is manned be down to ground time, then the other end rises to bottom housing 101, so that next escape personnel uses, so move in circles operation escape.
Based on above-mentioned life-saving high-altitude slow-falling device 100, the invention allows for a kind of escape system.As shown in Figure 5, this system comprises life-saving high-altitude slow-falling device 100, telescopic boom device 200 and a security rope 300.Telescopic boom device 200 comprises the telescopic arm 202 that a fixed part 201 and one and fixed part 201 are slidably connected, and wherein, fixed part 201 is fixedly connected on the weight-bearing surface of building.At the far-end hanging life-saving high-altitude slow-falling device 100 of telescopic arm 202, be fixedly connected with security rope 300 at telescopic arm 202 near high-altitude slow-falling device 100 place.
As shown in Figure 6, Figure 7, the fixed part 201 of telescopic boom device 200 is a sleeve pipe, and the top, two ends of sleeve pipe is fixedly connected with a flange 203, respectively for being fixedly connected with building.At internal surface of sleeve pipe, a pair elongated slide rail 204 is set.Telescopic arm 202 is provided with the rail wheel 205 that matches with slide rail 204 to realize being slidably connected of telescopic arm 202 and fixed part 201.
As shown in Figure 8, security rope 300 comprises a steel core safety rope 301, and the upper end of steel core safety rope 301 is suspended on telescopic arm 202 by a safety hook 302, and steel core safety rope 301 blocks extension one rope self-locking device 303.The lower end of steel core safety rope 301 can be preset anchor point with ground and is fixedly connected with and keeps tightening, flexible rail when declining as escape personnel, to prevent escape personnel from drifting about, and the phenomenon of colliding with metope.
Further, as shown in Figure 5, arrange a handle mechanism at telescopic boom device 200 fixed part 201 near one end of telescopic arm 202, handle mechanism comprises guide wheel 206, steel wire rope 207 and a handle 208, and wherein, guide wheel 206 is rotatably supported on fixed part 201; One end that handle 208 is fixedly connected on steel wire rope 207, the other end of steel wire rope 207 is fixedly connected on through guide wheel 206 one end that telescopic arm 202 is connected with fixed part 201.Like this, by pulling handle 208 that telescopic arm 202 can be made overhanging.
Further, be also fixedly connected with an escape handrail 209 at telescopic boom device 200 fixed part 201 near one end of telescopic arm 202, gripping before declining for escape personnel.
Further, at telescopic boom device 200 fixed part 201, a lock pin 210 for fixing telescopic arm 202 is also set near escape handrail 209 place, to prevent any slip of telescopic arm 202.
The occupation mode of escape system of the present invention is as follows: when escaping, telescopic arm 202 first pulls out by escape personnel from fixed part 201, then by the loins of one end of reciprocal rope 106 wrapped around oneself, the connection cord 304 of the rope self-locking device 303 be positioned on steel core safety rope 301 is firmly linked with in loins simultaneously, both hands are held escape handrail 209 and health are shifted out building again, and after loosing one's grip, human body just can be down to ground with a certain distance from wall is slow.When manned near ground, one end of reciprocal rope 106, then the other end rises, and next escape personnel just can repeat aforementioned escape and operate.
If escape personnel is slow midway falls when there is hypervelocity (> 1.5 meter per second) situation; rope self-locking device 303 will be locked jail voluntarily and stop declining on steel core safety rope 301; play the effect of secondary safeguard protection decline with this, the control spanner that escape personnel only must pull on rope self-locking device 303 when needing to continue to decline can be again slowly descending.
The present invention is only described with above-described embodiment, and the structure of each parts, setting position and connection thereof all can change to some extent.On the basis of technical solution of the present invention, all improvement of carrying out individual part according to the principle of the invention or equivalents, all should not get rid of outside protection scope of the present invention.
