Description
Technical field
The utility model relates to a kind of lifesaving appliance, especially relate to a kind of being used to when common floor or high-rise generation emergency save oneself the landing high-rise escape apparatus.
Background technology
At present the skyscraper in the city is more and more, and floor is also built higher and higher, and therefore, when meeting accident such as when fire or other disasters, under the situation that the passway for escaping of skyscraper is obstructed, the personnel escape in the skyscraper becomes a very big problem.Usually the personnel in the skyscraper when stranded, the rescue that need wait for rescue personnel just has the chance of escape disaster-stricken, the time that waits for rescue personnel might make trapped personnel lose best escape chance, causes bigger life and property loss.And common rescue mode, as the aerial ladder escape by rescue, but that aerial ladder sets up speed is slow, and is subjected to the aerial ladder limitation in height, can't implement the rescue of personnel on the higher floor; Another kind of mode is at the ground spreading air cushion, catch the survivor who jumps off from eminence, this rescue mode danger is bigger, and injured probability is bigger, especially the crowd of Shi Yinging is limited, old person or children are difficult to adopt this mode to be escaped, and this mode also is not suitable for the personnel's of higher floor place rescue.
The utility model content
The applicant is at above-mentioned problem, having carried out research improves, provide a kind of simple in structure, low cost of manufacture, easy to operate, be fit to that various crowds use, the rescue personnel to situation under realize the high-rise escape apparatus of saving oneself, on the situation that does not have rescue, can flee from skyscraper fast, reduce the probability that causes casualties, improve escape efficient.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of high-rise escape apparatus comprises:
Support;
Base takes the shape of the letter U, and device is on described support, and its two ends are provided with chute;
Friction plate is arranged on the bottom surface of described base;
The friction pulley assembly comprises runner, and the both sides of runner are provided with the friction pulley that contacts with described friction plate, and the outer end of friction pulley is by the axle connection bearing, and bearing slides in the chute of described base; When friction pulley abuts against on the friction plate, leave the gap between the bottom surface of bearing outer ring and chute;
Hawser is on the runner of described friction pulley assembly.
Further:
Coefficient of friction between described friction plate and the friction pulley equals the ratio of runner radius and friction pulley radius.
The runner of described friction pulley assembly is provided with two groups of hawsers, and the winding direction of two groups of hawsers on runner is opposite.
Comprise a supporting section that tilts on the described support.
Gap between the bottom surface of described bearing outer ring and chute is between 1～10 millimeter.
The end of described hawser is provided with the escape braces.
Technique effect of the present utility model is:
The disclosed a kind of high-rise escape apparatus of the utility model, simple in structure, low cost of manufacture, the user makes, and is fit to various crowds' uses and realization and saves oneself; Because the bearing at friction pulley assembly two ends slides in the chute of base, and select suitable friction pulley and the coefficient of friction between the friction plate (coefficient of friction equals the ratio of runner radius and friction pulley radius), make the survivor of different weight can obtain identical and constant decrease speed, both guaranteed that the survivor escaped fast, and be unlikely to injured again or cause more serious consequence; Be wound with two groups of hawsers that winding direction is opposite on the runner, after a survivor drop to ground, another survivor directly utilized another group hawser escape, is used alternatingly, and improves escape efficient.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Shown in Fig. 1,2,3,4, the utility model comprises support 1, and base 2 takes the shape of the letter U, and device is on support 1, and the two ends of base 2 are provided with chute 201, friction plate 3 by welding or other mode devices on the bottom surface of base 2.Friction pulley assembly 4 comprises runner 401, hawser 5 is on runner 401, the end of hawser 5 is provided with escape braces (not drawing in the drawings), two groups of hawsers 5 can be set on the runner 401, and the winding direction of two groups of hawsers 5 on runner 401 is opposite, when one group of hawser 5 when runner 401 unclamps, another group hawser 5 is wound on the runner 401, after can making a people utilize 5 escapes of one group of hawser, another person can utilize another group hawser 5 escapes, can effectively improve escape efficient.The both sides of runner 401 are provided with friction pulley 402, and friction pulley 402 contacts with friction plate 3, and the outer end of friction pulley 402 is by axle 403 connection bearings 404, and bearing 404 slides in the chute 201 of base 2.When friction pulley 402 abuts against on the friction plate 3, leave gap 6 between the bottom surface of the outer ring of bearing 404 and chute 201, this gap 6 is in actual applications usually between 1～10 millimeter.
In actual use, support 1 device in metope, is provided with a supporting section 101 (as Fig. 2) that tilts on support 1, can avoids the friction between hawser 5 and the metope, the angle of inclination of supporting section 101 can determine according to actual needs.When the personnel in the skyscraper need escape, can put on hawser 5 end the escape braces or hawser 5 tied up to waist, just can jump out escape.Because the bearing 404 at friction pulley assembly 4 two ends slides over the chute 201 of base 2, and when friction pulley 402 abuts against on the friction plate 3, leave the gap between the bottom surface of the outer ring of bearing 404 and chute 201, the deadweight of human body guarantees that friction pulley 402 abuts against on the friction plate 3, frictional force between friction pulley 402 and the friction plate 3 is slowed down people's decrease speed, to guarantee being unlikely to injured in the fugitive living process of human body.Select suitable friction pulley 402 and the coefficient of friction between the friction plate 3, can make the people descend or at the uniform velocity descend, both guaranteed quick escape, be unlikely to injured again with a suitable speed.
When the coefficient of friction between friction plate 3 and the friction pulley 402 equals the ratio of runner 401 radius r and friction pulley 402 radius Rs, survivor's decrease speed is only relevant with survivor's take-off speed (speed when hawser is tightened up) itself, irrelevant with survivor's body weight itself, that is to say that the survivor of different weight can obtain identical and constant decrease speed.Below this is made an explanation: suppose that survivor's body weight is G, the radius that twines the runner 401 of hawser 5 is r, and the radius of friction pulley 402 is R (obvious R＞r), the coefficient of friction f between friction plate 3 and the friction pulley 402.By mechanics principle as can be known, desire to make the object uniform motion, must make a concerted effort or resultant moment is zero.The pulling force of hawser 5 is survivor's body weight G, because in the friction pulley assembly 4 unsteady chutes 201 that are installed on the base 2, the pressure of friction pulley 402 on friction plate 3 also is G, should have when the moment that produces when the pulling force of hawser 5 and the moment of friction balance of friction pulley 402: G*r=f*G*R, therefore, f=r/R.
