Abstract
The utility model relates to a high building escape descending lifeline capable of directly controlling the descent speed. A triangular belt (3) rubber pressure ring (6) acts on a steel wire rope capstan (4) through a brake handle (12) and a tightening locknut (7) of a gripping handle (13) to produce friction damping action, so as to directly reduce the rotational speed of the capstan (4 descent speed), and realize controllable speed adjusting safety landing.
Description
The utility model relates to a kind of fire in high buildings urgent escape device, and is especially simple and reasonable, and the escape personnel can oneself control the escaping descent control device of decrease speed.
In a single day fire alarm takes place in skyscraper, and the high-rise personnel of resident family are occurred repeatedly because of elevator or passageway for fire apparatus are subjected to big fire to block the example that can't escape, use the descending lifeline tool and can bring life to above-noted persons.At present, existing descending lifeline tool often adopts complicated gear drive friction train, the decrease speed that modes such as oil hydraulic cylinder buffering are come reducing human, complex structure heaviness not only, make trouble, the cost height, and also decrease speed can not arbitrarily be controlled, some device also needs other people to assist to carry out, so be difficult to apply.
At the shortcoming of current escaping descent control device, the utility model provides a kind of safe ready, and is simple and reasonable, cheap individual escaping descent control device tool.
The technical scheme that its technical problem that solves the utility model adopts is: adopt in conjunction with two kinds of friction modes and directly realize regulation and control to steel wire rope capstan winch rotating speed.First kind is to have trapezoidal hole on the external diameter at capstan winch two ends, makes the friction in V belt and the trapezoidal hole of capstan winch realize braking deceleration by holding brake handle.Second kind is to cause the taper concave shape at the center at capstan winch axis hole two ends, respectively adorns a taper friction rubber ring at the main shaft two ends, makes rubber ring compressing capstan winch generation friction damping realize slowing down by tightening up urgent female exerting pressure to the center.
The beneficial effect of the new shape of this practicality is, the survivor holds descending lifeline slows down when descending, and can directly control decrease speed, and product structure is simple, and is with low cost.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a perspective view of the present utility model.
Fig. 2 is a front elevation view.
Fig. 3 is a side elevational view.
Fig. 4 is the longitudinal profile structural map of embodiment.
1. guide wheels among the figure, 2. steel wire rope, 3. V belt, 4. capstan winch, 5. rubber pressure ring, 6. main shaft, 7. compel female, 8. spring, 9. belt clamp, 10. pull bar, 11. supports, 12. brake handle, 13. handles.
In Fig. 4, the head end of steel wire rope (2) is connected to the fixed lock hook (not shown), hole and guide wheel (1) that the other end passes on support (11) top are coiled on the capstan winch (4), the axis hole that main shaft (6) passes capstan winch (4) and two rubber pressure rings (6) is fixed on support (11) middle part and tightens up with compeling mother (7), lower handle (13) is connected with support (11) with screw, intermediate inner wall has sliding tray can slide up and down brake handle (12) along groove, brake handle (12) is passed the belt clamp (9) on handle (13) and connection top, support (11) back by two ends cylinder lever connecting rod (10), tighten up V belt (3) side with screw below the belt clamp (9) and connect outside spring (8) by the stopper slot that screw passes support, the other end of spring (8) is articulated on main shaft (6) two ends.
When descending lifeline uses, the survivor has dressed safety belt (labour protection is with not drawing among the safety belt figure) earlier and it has been buckled on the descending lifeline handle (13), steel wire rope (2) is walked around window frame or other bearing column, the fixed lock hook (not shown) locking of head end is hung up properly, adjust the elasticity of compeling female (7), the rubber pressure ring (5) that makes main shaft (6) go up two ends is oppressed to the center, making rubs when rotated with capstan winch (4) produces damping action, hold the brake handle (12) on the tight handle (13), climb out of outside window then and slowly fall, degree of tightness by hand control brake handle (12), pulling force is passed on the V belt (3) by pull bar (10) belt clamp (9), V belt (3) is stressed to be pressed in downwards on the trapezoidal hole of capstan winch (4) and to hold tightly, when hand loosened, the spring (8) that connects belt clamp (9) drove V belt (3) and unclamps capstan winch (4) toward resilience, thereby realize controlled speed governing, make the survivor ground of arriving safe and sound.
Claims (4)
1. fall-slowing device for rescuing from high building.It is characterized in that: by the brake handle (12) on the handle of holding with a firm grip (13) with tighten up and compel female (7), make V belt (3) rubber pressure ring (6) act on capstan winch (4) and go up and produce friction, directly make capstan winch (4) rotating speed slow down.
2. fall-slowing device for rescuing from high building according to claim 1, its external diameter that is further characterized in that capstan winch (4) is divided into two-stage, has trapezoidal hole on the external diameter at two ends, and the taper concave shape is caused at the axis hole two ends.
3. fall-slowing device for rescuing from high building according to claim 1, it is further characterized in that brake handle (12), pull bar (10), belt clamp (9), spring (8), V belt (3) constitute retarding braking mechanism.
4. fall-slowing device for rescuing from high building according to claim 1, it is further characterized in that compels female (7), rubber pressure ring (6), main shaft (7) formation reducing gear.
