Abstract
A high-building lifesaving device comprises a casing. A bearing seat is set on the base and the main shaft is set on the bearing seat. The rope wheel is set on the main shaft and the inner-end of the rope is fixed on the rope wheel and the outer end of the rope is connected with the safety belt. A section of solenoid is covered on the rope. The arrester connected with the main shaft is set on the base. The arrester comprises a cubage-style liquid-pump and a liquid container whose outlets are connected with the flow limiter of thin-caliber pipe. The inlet and outlet are set on the liquid container. The inlet and outlet of liquid pump are respectively connected with the outlet and inlet of the container. The turning gearing-device with detents of ratchet wheel is set between the main shaft and the power input-axis of cubage-style liquid-pump. The utility model adopts the cubage-style liquid-pump whose outlet is connected with the flow limiter of thin-caliber pipe as an arrester, which can avoid the wearing and tearing during the use process and also can guarantee the equal speed of getting down. The utility model is safe and reliable and fits the repetitious use of many people.
Description
Technical field
The utility model relates to the brake of a kind of high-rise escape apparatus, particularly a kind of high-rise escape apparatus.
Background technology
When emergencies such as breaking out of fire on generation earthquake or the high building, the people on the high building need get off from high building fast, leave the disaster spot.On the high building, under passage be stair and elevator, when emergency takes place, people can get off from stair and elevator, if when emergency takes place, people fall over each other and take the road by force downstairs from stair and elevator, cause personnel crowded, greatly influencing people gets off from high building fast, leave the disaster spot, some people flees down because worry from window or balcony, be easy to cause tumble injury, also some people because worry look for a rope to hang out of the window or balcony under, with the hands hold rope and climb escape along exterior wall, escape may be because rope be shaky like this, rope falls short of, holding the not firm or decrease speed of rope can not control and meet accident and damage.For quick window or balcony from high building gets off, some people has designed high-rise escape apparatus, high-rise escape apparatus has rope-winding wheel that is wound with rope and the brake that links to each other with the axle of rope-winding wheel, the outer end of rope is connected with safety harness, during use, on one's body the people that desire is jumped out escape from window or balcony ties up to safety harness, jump off from window or balcony, brake can be controlled the rotating speed of rope-winding wheel, and the people is dropped on the ground safely evenly.In the prior art, mostly the brake of high-rise escape apparatus is friction brakes.The friction brakes of this high-rise escape apparatus produces resistance by the mutual friction of friction plate phase and brakes, in use, friction plate makes friction plate produce wearing and tearing because of the phase mutual friction produces high temperature, after friction plate has wearing and tearing, can not guarantee that the speed that descends is even, friction plate also can produce danger because of wearing and tearing make misfunctioning of brake when serious, and this high-rise escape apparatus also is unsuitable for many people and reuses.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, propose a kind of brake safe and reliable, be suitable for the reusable high-rise escape apparatus of many people.
The utility model is realized with the following method.
High-rise escape apparatus has housing, bearing block is arranged on the base, main shaft is arranged on the bearing block, one end of main shaft has crank, the rope-winding wheel that twines rope is arranged on the main shaft, the inner end of rope is fixed on the rope-winding wheel, the outer end of rope is connected with safety harness, be with one section solenoid on the rope, the brake that links to each other with main shaft in addition on the base, brake are positive displacement liquid pump and the liquid containers that outlet is connected with the thin diameter tube current limiter, and liquid container has liquid to advance, outlet, the liquid of positive displacement liquid pump advances, outlet goes out with the liquid of liquid container respectively, import links to each other, and is connected with the rotation transmission device with click between the power input shaft of main shaft and positive displacement liquid pump.
High-rise escape apparatus need be fixed in the high building room before use, the liquid container liquid of packing into.During use, on one's body the people that desire is jumped out escape from window or balcony ties up to safety harness earlier, can jump out the rope turning that the one section solenoid that is enclosed within on the rope is placed on window or the balcony from window or balcony, when the people descends, people's gravity pulling rope drives the rope-winding wheel forward rotation, the transmission device that rope-winding wheel rotates by having click drives the positive displacement liquid pump forward rotation that outlet is connected with the thin diameter tube current limiter, because the positive displacement liquid delivery side of pump is connected with the thin diameter tube current limiter, limited the flow of liquid, produce high pressure at the positive displacement liquid delivery side of pump, the rotating speed of positive displacement liquid pump is slowed down, be equivalent to the rotation of rope-winding wheel is played the effect of braking, under the effect of this braking, make the people drop on the ground safely evenly, after last personal security drops on the ground, people in the high building room can use crank backward rotation rope-winding wheel, safety harness is pulled repeated use, owing to be connected with transmission device between the power input shaft of main shaft and positive displacement liquid pump with click, can not drive the positive displacement liquid pump during backward rotation rope-winding wheel rotates, be enclosed within one section solenoid on the rope and be placed on rope turning on window or the balcony, prevent that the rope turning of rope on window or balcony is by window or balcony corner wear.
The positive displacement liquid pump that the utility model is connected with the thin diameter tube current limiter with outlet is as brake, and not wearing and tearing during use can guarantee that the speed of decline is even, safe and reliable, are suitable for many people's repeated uses.
Below in conjunction with accompanying drawing, the utility model is further described.
Description of drawings
Fig. 1 is that schematic diagram cuts open in the master office of looking of high-rise escape apparatus;
Fig. 2 is that schematic diagram cuts open in the side-looking office of high-rise escape apparatus.
The specific embodiment
Fig. 1, among Fig. 2, high-rise escape apparatus has housing 1, bearing block 2 is arranged on the base, main shaft 3 is arranged on the bearing block, one end of main shaft has crank 14, the rope-winding wheel 4 that twines rope 15 is arranged on the main shaft, the inner end of rope is fixed on the rope-winding wheel, the outer end of rope is connected with safety harness 5, be with one section solenoid 6 on the rope, the brake that links to each other with main shaft in addition on the base, brake is positive displacement liquid pump 8 and the liquid container 9 that outlet 13 is connected with thin diameter tube current limiter 7, liquid container has liquid to advance, outlet 10,11, the liquid of positive displacement liquid pump advances, outlet 12,13 go out with the liquid of liquid container respectively, import links to each other, and is connected with chain sprocket 18 transmission devices with click 17 between the power input shaft 16 of main shaft and positive displacement liquid pump.
