Abstract

A novel air inflation jacking lifting gear special for rescuing damaged aircrafts comprises an air inflation jacking body and a stabilizing support part. The structure of the air inflation jacking lifting gear is characterized in that firstly, the air inflation jacking body is formed by laminating a plurality of flat box-shaped unit air bags, when inflated with air, the air inflation jacking body is in a shape of a vertical square cylinder with a large volume; secondly, the stabilizing support part is formed by a plurality of cylindrical air bags and endless belts and is arranged between the top of the jacking body and airframe of the aircrafts, when inflated with air, the stabilizing support part can fill the wedge-shaped interspaces between the top of the jacking body and the airframe of the aircrafts. The air bags of the air inflation jacking lifting gear are made of high-strength flexible airtight materials, when not inflated, the air bags are small in size, low in weight, and easy to carry by labor; when in use, the air bags can be quickly jacked through a common air compressor and gas pipelines in a low pressure filling up mode. The contact is in a large-area and flexible mode, therefore the stable lifting of large-tonnage aircrafts is realized.

Description

The inflating and lifting hoisting device

Affiliated technical field

The utility model relates to a kind of low inflation jacking hoisting device, is applicable to that aerocraft meets accident when toppling fault enforcement emergency management and rescue, is convenient to the local or whole jacking fast of aerocraft is set upright.

Background technology

Civil aircraft is modernized express traffic transportation means, because its special frame skin structure has the advantages that volume is big, weight is big, surface strength is weak.The fault of toppling in case meet accident on ground needs lifting to set upright, even large-tonnage jack or hoisting crane are arranged, also is difficult to find desirable rigidity summit or lifting position; If whole lifting needs multi-point support or lifting, how to guarantee damaged aerocraft balance and stability, safe lifting a great problem especially.

Summary of the invention

Set upright difficulty in order to solve the conventional weight-lifting equipment rescue aerocraft lifting of toppling, the invention provides a kind of novel low inflation jacking hoisting device.This device is by the stacked jacking main body of forming of some flat box-like air bags, and its top is furnished with the stable support parts of some cylindric air bags and endless belt composition.This device air bag is made by flexible high strength gastight material, and unaerated state volume is little, and is in light weight, is convenient to the manpower transport; Just can fill the jacking of rising one by one fast by common Air compressor and gas line during use, form the vertical support square column of larger volume, lift the aerocraft stable elevation.

The beneficial effects of the utility model are, owing to be the large area flexible contact, inflation back operating pressure is no more than 0.1MPa, equal pressure and active area product principle according to application force, utilize the air bag low inflation jacking aerocraft that topples neither can cause passive safety, can obtain large-tonnage again and play heavy lift.Many cover airbag apparatus are used, and multi-point support can ensure that the aerocraft whole machine balancing is stable, safe lifting.

The specific embodiment

In the embodiment shown in fig. 1, some flat box-like unit air bags (1) stacked vertical is formed jacking lifting main body, charges into specified pressure pressurized air, is larger volume four directions bar shape; Its top is formed the stable support parts by 2 or 4 than cylinder with large diameter shape air bag (5) and its outer endless belt (6) of parcel; For ease of operation, every 3-5 unit air bag (1) can stacked be adhesively fixed into unit air bag group in the jacking lifting main body.

In embodiment illustrated in fig. 2, unit air bag (1) is made flat box-like independent closed air chamber by the high-strength flexible gastight material, it connects spacing up and down by wire drawing (8) isometric, that evenly gather equidistantly between aspect, can guarantee to charge into pressurized air rear gasbag aspect maintenance level up and down; Its outside face also has anti-skidding reticulate pattern (10) and anti-skidding connecting band (9), can guarantee the stacked inflation load of a plurality of air bags (1) after, still can keep whole vertical stable, can the slippage lateral deviation.Place the unit air bag (1) of jacking main body top layer or inferior top layer can be separated into 2-4 independent air chamber.Unit air bag (1) side wall center all around is provided with fluorescence labelling band (4), and four jiaos are provided with carrying handle (2), and the same side also is provided with self-closing charging connector (3) and pressure-limiting safety valve (7).

In the embodiment shown in fig. 3, form the stable support parts by 2 than cylinder with large diameter shape air bag (5) and its outer endless belt (6) of parcel.Each cylindric air bag (5) is made hollow independent air chamber by gastight material, is furnished with self-closing charging connector (3) and pressure-limiting safety valve (7); Its diameter 2-4 is doubly to air bag (1) thickness.Endless belt (6) outside face is provided with anti-skidding reticulate pattern (10), and its girth is answered 2 times to air bag (1) plane extreme length; The width of the length of cylindric air bag (5), endless belt (6) should be not less than the plane width of air bag (1).

In the embodiment shown in fig. 4, top lifting height on the estimation, select the stacked composition jacking lifting main body that rises of filling of some unit air bags (1) for use, the cylindric air bag (5) that two parallel interval are put in its top stable support parts is subjected to endless belt (6) restrained deformation after filling and rising, fill up aerocraft arc fuselage and unit air bag flat surface wedge gap, form stable ingot holding state; Increase simultaneously the contact action area again, guarantee air bag and aerocraft is evenly stressed, the lifting process balance and stability.

In the embodiment shown in fig. 5, overlap the inflating and lifting hoisting device more and be used, can very safely the whole lifting of huge aerocraft be set upright, precisely locate, for damaged aerocraft rescue maintenance facilitates.
