Description

Stair guard rail track escape car

Technical field：

The present invention is high-rise escape self-rescue equipment, belongs to mechanical field

Technical background：

With the development of society, building is built higher and higher and more, the escape for running into the accidents such as fire, people's air defense is help out of distress certainly Degree is also bigger.Escape mode most basic at present is escaped by stair, because building is too high, and walking is too slow when being downstairs, It is more difficult for handicapped person.

The content of the invention：

In order to overcome the slow-footed problem of existing stair escape, the present invention provides a kind of high-building self-help fast-escape equipment, Equipment speed of not only escaping is fast, and can lead and old, weak, sick, residual escape together.

The present invention solves the escape problem of saving oneself and adopted the technical scheme that, two individual components of three-dimensional track and three-dimensional coaster The escape car of composition：

(1) the three-dimensional tracks of：Using the guard rail of existing stair, on the premise of existing capability is not influenceed, by reinforcing Transformation, steel tubular handrailing is replaced with by wooden handrail, and the turning processing of handrail is in the arc-shaped, and the gradient is consistent, and this is three-dimensional track Upper rail；One of 50X50 millimeters of angle steel is welded in the middle part of the railing of guard rail, is lower railway, therefore forms three-dimensional track.

(2) the three-dimensional coasters of：The vehicle frame of coaster is one block of 8# channel-section steel, and a pulley is respectively installed at two of channel-section steel, vehicle frame A chair is welded in side, and vehicle frame is erected to the side of three-dimensional track, and pulley above is pressed against the upper side of upper rail, under Pulley leans against the lateral surface (shown in Fig. 2) of lower railway, because the radius of turn of upper rail (4) only has 8 centimetres, bends 180 degree, slope 30 degree of degree, therefore the three-dimensional coaster of single-sheaved block and the mode slided in curve inner side are employed, bend energy again can be passed through Centrifugal force is resisted, slides and matches on the outside of bend with lower sheave (16), three-dimensional coaster is formed.

According to the special shape and slope of three-dimensional track and three-dimensional coaster be steep, curved anxious track, devise normally closed type track and stop Car (9), behind vehicle frame, pin, hand can control, (Fig. 1,3 shown in) if normally closed brake failure, immediately using parking brake Car.What the speed slided was determined by the degree of pin or hand releasing of brake soon, slowly, do not get off the brakes and do not slide.

Self-actuating brake：Because three-dimensional coaster is in three-dimensional sliding on rails, turns and straight trip constantly changes, for safety, Corner should slow down, manually slow down on frequently bend, it is clear that difficulty is too big, thus using bend centrifugal force Automatic retarding is realized, mode is：One piece of friction plate (31) is fixed bottom in vehicle frame, and with lower sheave (16) and example, centre is Lower railway (17), in straight channel sliding, pulley abuts track, and when corner is slided, due to the effect of centrifugal force, pulley leaves Track, friction plate abuts track, produces frictional force self-actuating brake and slows down, friction plate also has the function of being oriented to and resist centrifugal force (track brake also has the function that guiding, self-actuating brake are slowed down), the success or failure and self-actuating brake for car of escaping are closely bound up.

In order to prevent three-dimensional coaster, track brake derailing, therefore auxiliary catch (13) is mounted with, is staggered with a reinforcing bar two 90 degree of bendings, following it is curved, be hooked in below lower railway (17), the curved of top abuts vehicle frame (3), take after people and to extrude solid naturally It is fixed not break off relations.

The beneficial effects of the invention are as follows：The speed of escape is slided into downstairs on 30 layers of building, is estimated one minute, in order to pacify Entirely, it is within two minutes benefit.Handicapped person is assisted to escape together, mode is-and handicapped person is sitting on car below, and operator sits On car above, a piece rope of connection in the middle of two cars, the front of rope is fastened on the trailer draw ring of front truck, the back of rope Fasten on the hand brake draw ring of rear car, when current vehicle is slided, because the normally closed brake that rope engagement handbrake unclamps rear car is slided, This method can make multiple escape cars while sliding.

In addition：Usually when elevator is out of service or walk-up building, difficulty in walking person can take escape car and go downstairs, Or sit escape car upstairs.Mode has two kinds, first：Employment is pushed, pulls on building, though manual work, relative to artificial lift Upstairs, or the mode in artificial back building is easily many, second：Automatic machine (45) upstairs：Slided using three-dimensional track and solid The ready-made condition of car, installs one of rack below lower railway, and electronic worm gear reducer is installed below chair, works as worm gear After the wheel and rack engagement of axle, opening motor will automatically upstairs.
