Abstract
The utility model relates to a folding jacking airbag which is characterized by comprising an airbag body 1, an upper and a lower bottoms 2 of the airbag and an airbag nozzle 3; the airbag body is provided with a plurality of pitch circle frameworks 4, and can be folded along the axial direction and expanded in the axial direction; and the bottoms 2 on both ends of the airbag bear the load. The utility model aims to solve the problem of providing a folding jacking airbag with the jacking height far more than the diameter, and overcome the deficiency that the jacking height of the prior airbag is restricted by the diameter of the airbag, thereby meeting the requirements of high-jacking projects, e.g. the elevation of bridges, aircraft jacking and the like.
Description
Technical field
The utility model relates to a kind of folding jacking air-bag, is a kind of lifting gear that uses on the engineering.
Background technology
The hoisting gasbag that uses in the present engineering all is columniform, it is cylindrical bus bearing load, the load-carrying capacity of this class air bag is very big, but owing to be subjected to the restriction of air bag diameter, its top lifting height is lower, and along with the increase of top lifting height, air bag with reduced by the contact surface of jacking object, its top lift sharply reduces, thereby can't satisfy the big engineering demand of top lifting height, for example as the rising of bridge, aircraft jacking etc.
The utility model content
Problem to be solved in the utility model provides a kind of top lifting height can overcome the deficiency that existing air bag top lifting height is limited by the air bag diameter much larger than the folding jacking air-bag of diameter, satisfies the demand of high height lifting engineering.
For addressing the above problem, the utility model by the following technical solutions:
Folding jacking air-bag is characterized in that: described folding jacking air-bag, form by the gentle Nang Zui that goes to the bottom on pneumatophore, the air bag, pneumatophore is provided with several pitch circle skeletons, pneumatophore can fold vertically, can axial stretching, utilize the end bearing load of balloon ends.
The top lifting height of described folding jacking air-bag and its diameter are irrelevant.
Pitch circle skeleton on the pneumatophore of described folding jacking air-bag only retrains the diametral load of pneumatophore, the diametral load that its radial constraint power is born greater than this solar term cyst wall.
The percentage elongation of the pitch circle skeleton on the pneumatophore of described folding jacking air-bag should be less than the percentage elongation of airbag wall.
The Valve for aerocyst of described folding jacking air-bag is on pneumatophore.
The cross section of described folding jacking air-bag is rounded, and promptly the end of air bag is rounded.
Described folding jacking air-bag is laemodipodiform at inflation rear gasbag body.
The material of described folding jacking air-bag is rubber or kiss-coating cloth or kiss-coating cord fabric or plastics or coating material.
Described folding jacking air-bag is the version that skeleton is arranged, and the cord spread pattern of its skeleton is that radial is arranged or oblique is arranged.
The framework material of described folding jacking air-bag can adopt the cord fabric of syntheticfibress such as polyamide fibre, polyester, viscose glue, or steel cord or glass fibre, carbon fiber, can use wherein a kind of of above-mentioned material, also can unite use by two or more materials.
Beneficial effect
The top lifting height of folding jacking air-bag described in the utility model is not subjected to the restriction of its diameter, utilizes the end bearing load of balloon ends, and no matter the air bag top lifting height has muchly, and its active area is constant, and top lift can not change yet; Air bag is folding vertically, and magnification ratio can reach 15: 1, and for example fold height is the air bag of 0.5m, and its top lifting height can reach 7.5m.
The utility model is described in further detail below in conjunction with drawings and Examples:
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model folding jacking air-bag;
Accompanying drawing 2 is the partial enlarged drawing of accompanying drawing 1.
Among the figure: the 1st, pneumatophore, the 2nd, the upper base of air bag and going to the bottom, the 3rd, Valve for aerocyst, the 4th, pitch circle skeleton.
The specific embodiment
Embodiment 1, as shown in Figure 1, 2, is used for the folding jacking air-bag of aircraft jacking, form by pneumatophore 1, the upper and lower end 2 of air bag, Valve for aerocyst 3, pneumatophore 1 is provided with several pitch circle skeletons 4, and pneumatophore 1 can fold vertically, can axial stretching, going to the bottom of air bag 2 supported on the ground, the upper base 2 of air bag withstands the aircraft ventral, and the diameter of air bag is 1.5m, and the height behind the airbag fold is 0.3m, top lifting height is 3.6m, and the top lift of air bag is 90 tons;
Embodiment 4, and the cord of the skeleton of folding jacking air-bag adopts the oblique arrangement architecture, adopt the cord fabric of syntheticfibress such as anti-polyamide fibre of subduing, polyester, viscose glue, or glass fibre, carbon fiber are done framework material;
Embodiment 5, the pitch circle framework material of folding jacking air-bag can adopt the low steel cord of percentage elongation or glass fibre, carbon fiber, or the cord fabric thread of syntheticfibres such as polyamide fibre, polyester, viscose glue, the diametral load that the radial constraint power of pitch circle skeleton should be born greater than this solar term cyst wall;
