Background technology
At present, what escaping device for high-rise building was more famous is the descending lifeline of army of the company invention that CCTV broadcasts, but, in fact there is many deficiencies in this patent, if hundred floor height buildings, just there are 400 to 500 meters high, the highest floor iron chain needs 800 to 1000 meters, iron chain length is the heaviest, the long-term heap of a lot of iron chains is there, for a long time need not ensure, motility when whether getting rusty and use is all challenge, hoist occurs getting stuck much, furthermore, it is also required to look for a place being, for striving and point robbing the people that the second is eager to flee for life, finding the object being suitable for hitching also is a challenge, were it not for the object that can be or tying insecure be all problem;In addition 201010585457.5 also have same problem, where i.e. tie up to, and the length of steel wire rope is not easy to solve;And the security against fire hidden danger of some high buildings there is also, general fire pump vehicle is the highest also can only achieve more than 60 meter, and the most about 20 floors are high, but the high building of present up to a hundred meters can be found everywhere;Applicant is as a rural migrant worker, the construction once having skyscraper field is experienced, scaffold is taken in present skyscraper alien invasion construction needs substantial amounts of bamboo and wood materials or steel pipe, these materials expose to the sun and rain, waste is serious, do not meet very much environmental requirement, and, take and tear open be required for substantial amounts of manually, also danger close, which increase construction cost, the work such as alien invasion decoration construction that some have built up and curtain wall maintenance is more dangerous, it is all fixing due to scaffold, construction is not very convenient yet, when rural migrant worker constructs the most arduous, these interim scaffolds often there is also many potential safety hazards, from the rural migrant worker that scaffold falls also time have what is heard.
Summary of the invention
Beneficial effect:The escape device of present invention design can be escaped in a large number, and simple in construction, low production cost, production equipment need not too many investment, and safety is high, it is suitable for fire-fighting or maintenance simultaneously, construction use, fire fighter or maintenance personnel and builder can arrive at rapidly required floor by slide rail and be operated, and construction can reduce a part by the present invention and take the work tearing scaffold open, save the raw materials such as part bamboo wood, alleviate work risk and the labor intensity of rural migrant worker.
Technical scheme:The technical scheme is that, power set are not used to complete escape, by offsetting part action of gravity, thus speed protection human-body safety when reducing downslide, it is characterized in: human bady gravitational traction slide device glides, slide rail arranges energy conversion device with glider, utilize frictional force or some other mode etc. that gravity is offset a part, the speed that so reducing human glides, in addition, during downslide to be looked after at the uniform velocity with safety, the present invention passes through rack pinion, the vertical downward movement of gravity is converted into circular motion, realize at the uniform velocity and safety, whole device is made up of three parts, slide rail, glider, emergency exits, slide rail is preferably attached on exterior wall, operation glider is then driven by power, it is provided with self-locking device, alarm triggering device it is provided with to prevent from illegally using slide rail on slide rail.
Slide rail has a following characteristics:
1: slide rail has groove position or other structural support gliders that can fix glider to work;
2: slide rail has the at the uniform velocity slow fall holding components of glider, and example is tooth bar, and it coordinates with the gear of glider, and then drives slow fall component working;
3: warning trigger unit;Example is feeler lever hole, and feeler lever hole should enter alarm triggering device with preventing rainwater from flowing backward obliquely.
Glider by delaying fall parts, seat belt, human body trample foot rope, fixing disengaged part, brake part etc. form, glider is preferably disposed near emergency exits or escape slide rail at ordinary times, conveniently takes in order to time critical, is characterized in:
1: slow fall parts are a laborious device or descending lifeline etc., carry out reduction of speed by offsetting part action of gravity;
2: fixing disengaged part is exactly that glider and slide rail can complete the fixing parts run and glider departs from slide rail, fixing disengaged part is by gim peg position, movable bolt and positioning screw composition, gim peg position is typically formed when casting or manufacture glider body, not individual components, the groove position of gim peg position and slide rail completes to fasten, and movable bolt is made up of groove position and bolt position, the bolt tongue insertion groove position of glider, then groove position with slide rail, bolt position completes to fasten, screwed in place screw rod, i.e. can use;
3: operation glider and life-saving glider are similar, different one is that it uses motor equal power device such that it is able to lift, two is to have some fire-fighting equipment hanging members or instrument to put facility above it, the lightweight material such as fire extinguisher or fire extinguisher canvas hose or instrument can be transported in the lump, operation glider can make maintenance slide rail, fire-fighting use and construction use, and three is that it have employed power failure or power-off self-actuating brake design.
Detailed description of the invention:nullDuring escape,Glider is placed on slide rail,First gim peg side is advanced the groove position of slide rail,Again glider base bolt tongue propelling activity croze position is blocked,Movable bolt position is advanced the slot of slide rail,Screwed in place screw,Afterwards by tight brake,People station is up,Fasten seat belts,Releasing of brake device,Now people glides together with glider,After people lands,Unclamp set screw,Activity croze position is pushed away glider base,Descending lifeline just can be taken away,To facilitate people below,Glider can be turbine or the slow descending device such as gear deceleration or descending lifeline,Double and single use different speed reducing ratio should be set,Trampling foot rope is exactly preferably steel wire rope or iron chain etc,Light the most fire-resistant,Length is about at about 1 to 1. 5 meter,Bottom arranges pedal,Trample foot rope and seat belt is all attached to above glider,Trample foot rope and seat belt can be provided with certain telescopic adjustment function,To adapt to the fat or thin crowd not waited of height,There are chamfering or fillet in movable bolt and gim peg both sides,With the anti-jamming feeler lever that maybe cannot promote warning,And its contact of the feeler lever reported to the police be hemispherical or other be difficult to the shape that is stuck,For safety,Groove bit width should control with the degree of depth in the case of ensureing safety,Alarm triggering device is prevented to lose efficacy,The groove bit depth of slide rail and width are preferably not more than 5mm,And contact blade spring props up,During glider work,Contact can submerge in slide rail completely,But,As long as between contact is supported into about 1 to 2mm,Just should cause trigger action,So,Lawless person be just difficult with slide rail enter high building and not detectable,In addition,If people's decrease speed on upper strata is fast,Can directly step down on following descending lifeline,And brake gear time to be decrease speed too fast by glider reduction of speed or stuck on slide rail,General utilization operates handle and brake block or brake rim etc.,Slippy people can not also use.
Operation glider is for safety, there is a self-locking device, namely self-actuating brake, ultimate principle is unclamped when being exactly up, automatic locking running gear when stopping up, a ratchet is had at electric machine main shaft or other suitable places, it is arranged above with ratchet at glider, and have weight to hang on ratchet, during installation, note profile of tooth direction, when glider runs up, ratchet can separate with ratchet, when power-off or power failure, under gravity, glider can glide, now, motor shaft inverts, ratchet clasps ratchet, glider is made to stop gliding, when needing to glide, have only to lift weight, by pawl ratchet separately.
At the realm of building construction, the width of general house is about 4 meters, so, two the slide rail spacing more adjacent than relatively large skyscraper are also about this standard, as long as costing suitable pedal between two slide rails, ensureing that certain safety condition just can be constructed, such scaffold can rest on any height.
