Abstract
The utility model relates to a high-altitude escape descent control device, which comprises a roller (1), a rope (2), a bull gear (3), a pinion (4) and a descent control device (5), wherein the descent control device (5) is a centrifugal force mechanical uniform-speed device; the centrifugal force mechanical uniform-speed device comprises a circular shell (51), a runner (52), a plurality of friction blocks (53) and a plurality of connecting rods (54); the runner (52) is fixed at one end of a gear shaft of the pinion (4), and is positioned at the middle position of the circular shell (51); and each friction block (53) is hinged on the circumference of the runner (52) through one connecting rod (54). The high-altitude escape descent control device has a simple structure, is convenient to use, and is safe and reliable; and people in danger on a high-rise building can escape independently, quickly and safely.
Description
Technical field
The utility model relates to a kind of fire-fighting equipment, relates in particular to the high altitude escape slow descending device that high-altitude emergency escape in danger or emergency relief are used.
Background technology
In today of economic develop rapidly, the skyscraper in city is more and more, floor is also more and more higher, thereby the possible shape of the dangerous situation that meets accident in the skyscraper also increases thereupon, in case generation dangerous situation, such as fire, live in the people in the skyscraper, must escape rapidly, and from people's escape aspect, if select to escape in flurried from stair, certainly will personnel crowd, situation is changed unrest, very easily cause the generation of the accident of trampling, and when breaking out of fire or other disasters, what at first be damaged is that place floor even entire building get electric power system, therefore, select that elevator is then more inadvisable also need be avoided, multiple situation all may cause distress personnel in time to escape, and need wait for rescue, and from external rescue, if fire occurs in higher floor, then rescue aerial ladder and can not arrive specified altitude assignment, thereby also can't save distress personnel, if at the on-the-spot spreading air cushion of suing and labouring, allow distress personnel jump off,, usually can't realize rescue smoothly then owing to the restriction that is subjected to the air cushion size and other multiple reasons from eminence.
In order better to overcome existing defective, designer of the present utility model has designed the device that can provide the high-altitude to recover by long-term design and experiment repeatedly.
Summary of the invention
The purpose of this utility model is to provide a kind of high altitude escape slow descending device, and it is simple in structure, and is easy to use, safe and reliable, make on skyscraper people in danger can be independently safe escape rapidly.
For achieving the above object, the utility model discloses a kind of high altitude escape slow descending device, this slow descending device comprises running roller 1, rope 2, gear wheel 3, pinion 4 and descending lifeline 5, running roller 1 is installed in the shell of slow descending device by bearing, rope 2 one ends are fixed on the running roller 1 and are wrapped on the running roller 1, and an end of running roller 1 is connected with gear wheel 3 and both together rotate, pinion 4 and gear wheel 3 engagement rotations, one end of the gear shaft of pinion 4 is connected with descending lifeline 5, it is characterized in that:
Descending lifeline 5 at the uniform velocity installs for a kind of centrifugal force machinery, described centrifugal force machinery at the uniform velocity device comprises circular shell 51, runner 52, a plurality of brake pad 53 and a plurality of connecting rod 54, runner 52 be fixed in pinion 4 gear shaft an end and be positioned at the centre position of circular shell 51, each brake pad 53 all is articulated on the circumference of runner 52 by connecting rod 54.
Wherein, the other end of rope 2 is fixed with bundling belt or binding vest.
Wherein, an end of running roller 1 is connected with gear wheel 3 by shaft coupling.
By said structure, high altitude escape slow descending device of the present utility model utilizes rope to be wrapped on the running roller on the one hand, provides people can drop to ground from the high-altitude smoothly, slows down the speed of people's landing on the one hand by descending lifeline, and safety guarantee further is provided.
Detailed content of the present utility model can obtain by explanation described later and institute's accompanying drawing.
Description of drawings
Fig. 1 has shown the schematic diagram of high altitude escape slow descending device of the present utility model.
Fig. 2 has shown the schematic diagram of descending lifeline of the present utility model.
Fig. 3 has shown the side view of descending lifeline of the present utility model.
The specific embodiment
Referring to Fig. 1, the schematic diagram that has shown high altitude escape slow descending device of the present utility model, this slow descending device comprises running roller 1, rope 2, gear wheel 3, pinion 4 and descending lifeline 5, its middle roll 1 is a cylindrical tube, its two ends are by in the shell (not shown) of the rotatable installation slow descending device of bearing, one end of rope 2 is fixed on the running roller 1 and is wrapped on the running roller 1, the other end of rope 2 preferably is fixed with bundling belt or binding vest, thereby provide better binding effect, a wherein end of running roller 1 is connected with gear wheel 3 and together rotation with it, preferred running roller 1 connects this gear wheel 3 by shaft coupling, pinion 4 and gear wheel 3 engagement rotations, an end of the gear shaft of pinion 4 is connected with descending lifeline 5.
Wherein, descending lifeline 5 at the uniform velocity installs for a kind of centrifugal force machinery, described centrifugal force machinery at the uniform velocity device comprises circular shell 51, runner 52, a plurality of brake pad 53 and a plurality of connecting rod 54, runner 52 be fixed in pinion 4 gear shaft an end and be positioned at the centre position of circular shell 51, each brake pad 53 all is articulated on the circumference of runner 52 by connecting rod 54.
When high altitude escape slow descending device of the present utility model moves, the escape personnel is as long as on one's body being bundled in the free end of rope, determined to jump off behind the height, because the influence of the earth's core gravity, escape personnel's speed constantly increases, the speed of running roller also constantly increases, be rotated by the gear wheel pinion mate thus, the rotation of drive runner, thereby the brake pad around the runner outwards launches, with the circular shell friction so that cushion effect to be provided, the pulling escape personnel reduces sinking speed, thereby ensures escape personnel's safety.
