Abstract

The invention provides a life saving device which enables people trapped in a building to quickly escape when a fire breaks out or an earthquake happens or other emergencies happen in the building. A safety rope sheave is connected with an inner gear through sunk screws in a cylindrical shell, the inner gear, three transmission gears and a center gear are sequentially meshed, low rotation speed of the safety rope sheave is increased fourfold when transmitted to the center gear, a center gear shaft drives two ratchets and two gear plates to rotate, two speed limiting forks control rotation speeds of the two gear plates respectively, finally the rotation speed of the safety rope sheave is reduced, and accordingly operation speed of a safety rope is controlled.

Description

Fire hazard of storied house earthquake life-saving device

Affiliated technical field

The present invention relates to one in the time of the emergency situations such as building breaking out of fire, earthquake, when elevator & stairs cannot normally use, the lifesaving appliance that in building, all trapped personnels are fast and safely downstairs escaped.

Background technology

At present known when building breaking out of fire, elevator definitely can not use, and can people be trapped in elevator because fire has a power failure suddenly, and pyrotechnics can suffocate from the elevator rising personnel in elevator that cause.Stair also can be blocked by pyrotechnics because of stack effect, cannot escape.Some people Ze Yin cannot stand that smoke fire is roasting or panic and blindly escape as jump out of the building etc. can cause meaningless injures and deaths.The rope of some lifesaving appliance makes of nonfireproof material, as elasticity cloth bag slideway, when having flame, certain window scurries out, burn rope or cloth bag and will cause the danger that people falls down from the building downstairs, some lifesaving appliances are to do power with battery, also can make electric weight naturally consume because the resting period is long many, once in case of emergency, electric weight deficiency or personnel drop to a half electric weight and exhaust and larger danger occurs.

In most cases, can only rely on fire brigade's aerial ladder to rescue people, or fire fighter carries oxygen tank on the body, wear breathing mask from stair upstairs, in dense smoke, each room of each floor looks for people to rescue people, so not only fire fighter is caused to potential danger, (in fire hazard of storied house of Hengyang, Hunan Province, just, because fire fighter enters building rescue trapped personnel, cause 20 firefighters sacrifices, also have more than 20 fire fighter injured.) trapped personnel also can be because sucking dense smoke for a long time in building, toxic and harmful cause casualties.If fire spot does not have fire brigade or far away apart from fire brigade, or near the road in the building that catches fire is narrow, there is the barrier such as automobile, sand drift both sides, road, fire fighting truck leaves to come in, or there is the thing such as low tension wire, optical cable downstairs, aerial ladder cannot erect rescues people etc., in these situations, will waste waiting for rescue of many valuable very much time passivenesses, cause this evitable casualty loss, the chance that makes to escape greatly reduces.

In March, 2009, fire brigade of Beijing spent high price to buy fire hazard of storied house escaping slideway, need to support cloth bag slideway with motor ladder, but was subject to motor ladder height, electric wire, cable, wind speed limit before catch fire near road building, building.

Summary of the invention

When overcoming the emergency situations such as real building breaking out of fire earthquake, can only passive wait for rescue or shortcoming that blindly escape etc. causes injures and deaths, the invention provides a kind of safe ready and control fast and automatically fast selfrescue equipment---fire hazard of storied house earthquake life-saving device.Once send a people or two people downstairs, can recycle.

This equipment also can be used as instrument clean or finishing building outside metope.

The technical solution adopted for the present invention to solve the technical problems is: in a cylindrical outer casing, a safety rope sheave between two parties, just to there being a rectangle rope hole on the cylindrical outer casing of safety rope sheave, outside rectangle rope hole, be truckle frame, three truckles are fixed on truckle frame by three stove bolts.Safety rope is through first, between second truckle, through the rectangle rope hole on cylindrical outer casing, in groove on safety rope sheave around one week, between rectangle rope hole, second, the 3rd truckle, wear out again, replication is next separately for two safety rope fag ends, becomes a safe becket bridle respectively with dop card.On the cylindrical outer casing of corresponding pulley yoke another side, there is a safety door hook link, on link, hang a safety door hook.

Safety rope sheave left side connects an internal gear with sunk screw, internal gear is inboard to be connected with a joggle with three travelling gears simultaneously, these three travelling gears are connected with a joggle with a central gear again simultaneously, three travelling gears, central gear all and the axle of oneself be one.With three sunk screws, three travelling gears, central gears are connected in tooth rest outer plate and tooth rest between sheet, tooth rest outer plate is fixed on cylindrical outer casing again.The number of teeth of internal gear is more than four times of central gear, so internal gear turns around with safety rope sheave, it is many that central gear is just turned four circles by internal gear by three travelling gears drives.

Safety rope sheave right side is fluted disc A and fluted disc B, is ratchet A on fluted disc A, is ratchet B on fluted disc B, and ratchet A can only forward, and ratchet B can only reverse.Between fluted disc A, fluted disc B and cylindrical outer casing, be a speed limit crotch, on speed limit crotch, have speed limit fork A and speed limit fork B, speed limit crotch is connected in cylindrical outer casing with two sunk screws.Sun gear shaft right-hand member passes the centre bore of safety rope sheave, then passes the centre bore of ratchet A and ratchet B, and spindle nose is connected on cylindrical outer casing with No. 6000 bearings.

On the outside corner of wall of window one side, with boring a deep hole, in hole, fix an expansion bolt that has hanging hole.Prepare again three, four safety belts, on each safety belt, have a safety door hook.Urgent need when these safety belts and brucker survival capsule are placed on to place that a house-owner knows in order to emergency case.

Work as breaking out of fire, when earthquake emergency situation elevator stair cannot use, take out brucker survival capsule, in the hanging hole of the expansion bolt on the wall of the safety door hook hook on brucker survival capsule, one people or two people fasten seat belts and the safety door hook on safety belt are hooked on the safe becket bridle in the short one end of brucker survival capsule, both feet stretch out unsettled outside window, under the Action of Gravity Field of human body, safety rope just drives safety rope sheave to clockwise rotate, safety rope sheave drives internal gear synchronously to rotate, internal gear drives again three travelling gears to clockwise rotate, three travelling gears drive central gear to rotate counterclockwise again, because the number of teeth of internal gear is more than four times of the central gear number of teeth, so be exactly more than four times of internal gear rotating speed by the rotating speed of speed ratio central gear, sun gear shaft just drives ratchet A and fluted disc A forward, tooth on fluted disc A is stirred speed limit fork A and is swung, speed limit fork A has just controlled the velocity of rotation of fluted disc A like this, thereby control the rotating speed of internal gear and safety rope sheave by central gear and transmitting gear, now ratchet B does not work, fluted disc B and speed limit fork B also do not work.In the time that the first arrival is unfastened one's seat-belt downstairs, the safe becket bridle in one end also moves near brucker survival capsule in addition, an other people has also fastened seat belts and the safety door hook on safety belt has been hooked on safe becket bridle, both feet stretch out unsettled outside window, now safety rope drives again safety rope sheave to rotate counterclockwise in the other direction, safety rope sheave drives internal gear synchronous rotation counterclockwise, internal gear drives again three travelling gears to rotate counterclockwise, three travelling gears drive central gear to clockwise rotate again, ratchet A on sun gear shaft, fluted disc A and speed limit fork A have not worked, ratchet B starts reversion, drive speed limit fork B to swing, speed limit fork B controls fluted disc B, ratchet B and central gear, internal gear, the rotating speed of safety rope sheave, the final translational speed of controlling safety rope.So circulation, until all rescue high tower all trapped personnels.

If clean or whitewash flooring, glass, while the hanging operation such as installing an air-conditioner, pincer folder is arranged on brucker survival capsule truckle frame, again one end of short safety rope on brucker survival capsule is used on the abovestairs fixture of safety door hook hook, safety door hook on brucker survival capsule shell is hooked on the becket bridle at a plank center, people is sitting on plank and uses safety belt to be connected with brucker survival capsule, slow decreasing clutches and fixes the pincer folder on brucker survival capsule during to the position of needs, two strands of safety ropes are crowded together can not be moved, brucker survival capsule just rests on fixed position, unclamp the pincer folder on brucker survival capsule when completing the work of this position, can drop to again other positions works on.

The invention has the beneficial effects as follows: when building breaking out of fire elevator can not use, stair are blocked by pyrotechnics, when bad stair of Earthquake can not use, trapped personnel need not wait for rescue in passiveness, waste valuable escape time and increase injures and deaths, blindly in pyrotechnics, find escape road, the escape of jumping out of the building etc. and create extra casualties, but utilize this brucker survival capsule safe and effective, actively save oneself quickly and easily, reduce to greatest extent casualties.After in building, trapped personnel is all gone downstairs safely simultaneously, fire brigade is once can put out a fire at once to on-the-spot with all strength, need not separate manpower rescue trapped personnel, can reduce while entering building search trapped personnel because of fire fighter, raging fire dense smoke, toxic and harmful, burnt the article that drop, even building such as is burnt down at the injury that situation causes fire fighter.Rescue people without redirected staff, can full entry fire extinguishing, can greatly shorten again time of fire extinguishing, alleviate and extend the material damage and the burned for long time that cause ignition time and discharge a large amount of dense smoke, toxic and harmful pollution on the environment.
