Abstract
The invention discloses a jacking air cushion used for jacking a heavy weight, particularly to a circular jacking air cushion. The circular jacking air cushion comprises a rubber skin sac, wherein an inner reinforcing metal plate is arranged at each of the upper and lower ends inside the rubber skin sac; an inflation valve is arranged on the rubber skin sac; a non-slip mat is arranged at each of the upper and lower ends outside the rubber skin sac; the inner reinforcing metal plates, the rubber skin sac, the non-slip mats and bearing metal plates are hermetically connected into an integrated body through screw plugs; the rubber skin sac is of a layered structure, and is formed through overlaying rubber inner skin, pressureproof fibers and rubber outer skin; and a handle is arranged on the rubber skin sac. According to the jacking air cushion, the bearing metal plates are designed at the top and the bottom of the rubber skin sac, better contact surfaces are provided, the air cushion is more stable during inflation and jacking, when the jacking air cushion is utilized to jack the heavy object, the bearing metal plates can bear higher load, a plurality of air cushions can be overlaid through the bearing metal plates, and the jacking height of the heavy object is increased; and the air cushion is circular, so that the jacking air cushion can bear higher inflation pressure and is not liable to burst.
Description
Technical field
The present invention is a kind of jacking air cushion for jacking weight, particularly a kind of circle jacking air cushion.
Background technology
The operation principle of jacking air cushion is expansive force when being expanded using air cushion inflation by weight jack-up.Existing jacking
Air cushion is square air cushion, because square air cushion is little with the contact surface area of weight, so causing jacking unstable, is also easy to make
Air cushion damaged surfaces；Square air cushion adopts pressing mold molding, and the blowing pressure born is less, easily causes explosion when overvoltage；
Square air cushion cannot be connected with another air cushion superposition, so top lifting height is restricted.
Content of the invention
The invention aims to overcoming existing square jacking air cushion jacking unstable, easy explosion, can not being superimposed
Defect, a kind of load bearing metal plate that is provided with of invention lifts contact surface performance, improves the circular jacking air cushion of jacking stability.
The purpose of the present invention to be realized as follows：Described circle jacking air cushion, including a rubbery human body, rubber
The intracapsular upper and lower ends of rubber are respectively equipped with an internal reinforcement metallic plate, and rubbery human body is provided with charge valve, outside rubbery human body
Upper and lower ends be respectively equipped with a slipmat, internal reinforcement metallic plate, rubbery human body, slipmat and load bearing metal plate pass through plug screw
It is close contact in one.
Described rubbery human body is layer structure, is formed by stacking by rubber endothelium, pressure fiber and rubber crust.
Described rubbery human body is provided with and handles.
The positive effect of the present invention is as follows：The present invention, in the top of rubbery human body and bottom design load bearing metal plate, carries
Supply more preferable contact surface so that air cushion is more stable in inflation and jacking, in jacking weight, load bearing metal plate can bear
Multiple air cushions can be superimposed by load bearing metal plate, improve the top lifting height of weight by bigger load；Because air cushion is round
Shape, so bigger the blowing pressure can be born, and it is difficult to burst.

Specific embodiment
As shown in figure 1, described circle jacking air cushion, including a rubbery human body 1, the upper and lower ends in rubbery human body 1 are respectively
It is provided with an internal reinforcement metallic plate 2, rubbery human body 1 is provided with charge valve 3, the upper and lower ends of rubbery human body 1 outside are respectively equipped with
One slipmat 4, internal reinforcement metallic plate 2, rubbery human body 1, slipmat 4 and load bearing metal plate 5 are close contact in one by plug screw 6.
Described rubbery human body 1 is layer structure, by rubber endothelium 1-1, pressure fiber 1-2 and rubber crust 1-3 superposition
Become.
Described rubbery human body 1 is provided with and handles 7.
Using front, air cushion is in flat, sees Fig. 2.During use, inject pneumatic air from charge valve, reach in rubbery human body
Pressurize in portion, rubbery human body will expand into the design top lifting height of maximum, sees Fig. 3.The jacking ability of the present invention is by pressure
It is multiplied by contact area (lifting surface area) to calculate.The slipmat of the upper/lower terminal of air cushion can strengthen curable grip, internal reinforcement
Metallic plate can strengthen internal structure, and load bearing metal plate is provided that more preferable contact surface, improves stability during jacking.Outside rubber
Micromicro protects pressure fibrous tissue, and pressure fiber can bear bigger internal pressure, and in rubber, micromicro prevents gas leakage.The present invention can
Stack up use, and its practical state is shown in Fig. 4.
