Abstract
The invention relates to strip-shaped lifting air bag, which is characterized in that the strip-shaped lifting air bag comprises an air bag body 1, an air bag head 2 and an air bag nozzle 3; the cross sections of both the air bag body and the air bag head are flat; the height H of the air bag is 10 to 150mm; the air bag can be conveniently placed at the lower end of a component to be lifted; the operating air pressure of the air bag can reach 3Mpa; the lifting capacity of the air bag can reach more than 450 tons per meter; and the lifting capacity of a single strip-shaped air bag can reach thousands tons, so that only 2 to 3 air bags can meet the lifting requirement of components with the weight of thousands tons, even more than tens of thousands tons.
Description
Technical field
The present invention relates to a kind of lifting gear, relate to a kind of hoisting air chamber that can lift large-scale component specifically.
Background technology
The capsule body that is used for the air bag of lifting at present all is columniform, it is conical or hemispheric that its head is, during the air bag unaerated, its head then is the pot shape of back-off, and projection higher (shown in Figure 11,12), the cylindrical air bag of 1 meter of diameter for example, the height of its head projection is generally more than 260mm, be difficult to fill in below the member of desiring lifting, make troubles to operation.The diameter of air bag is big more, its head projection high more.The cross-sectional plane of the air bag body of cylindrical air bag after inflation, head is all rounded, because its head is hyperbola, under heavy lift, air bag head unbalance stress, during airbag aeration, deflection is big, air bag head and member bottom friction power are very big in the lifting process, cause undue wear easily and cause explosion, so the pressure of the safety relatively poor this air bag of this air bag when the carrying heavy lift generally is no more than 0.8MPa, every meter load-carrying ability of air bag is below 80 tons.In the modern times construction, the volume and weight of member is increasing, the caisson of using as the harbour, the taking and discharging mouth in power station, bridge, boats and ships, drilling platform etc., the member that has weigh thousands of tons of even ton up to ten thousand, how safety, to lift these buster easily are problem demanding prompt solutions.
The patent No. 96227002.4,200510042556.8,200620018573.8 and 03216574.9 disclosed air bag capsule body is cylindrical, and the air bag head is cylindrical-conical.
Summary of the invention
Problem to be solved by this invention designs a kind of air bag exactly, can be placed on easily below the member of desiring lifting, and can bear bigger pressure and load, only just can satisfy the lifting requirement of weight at thousands of tons of even the member more than tens thousand of ton with 2-3 bar air bag.
For addressing the above problem, the present invention by the following technical solutions:
Bar shaped hoisting air chamber is characterized in that: described bar shaped hoisting air chamber is made of air bag body, air bag head and Valve for aerocyst, and the cross section of its air bag body and air bag head all is flats.
Below be the further improved technical scheme of such scheme:
Described bar shaped hoisting air chamber is the height of flats between 10～150mm.
The aspect ratio of described bar shaped hoisting air chamber is between 2:1～25:1.
The aspect ratio of described bar shaped hoisting air chamber is between 4:1～16:1.
Described bar shaped hoisting air chamber generally respectively is equipped with a Valve for aerocyst in balloon ends.
Described bar shaped hoisting air chamber is equipped with a Valve for aerocyst.
Described bar shaped hoisting air chamber is equipped with four Valve for aerocyst.
The Valve for aerocyst of described bar shaped hoisting air chamber can be arranged on the midway location of air bag head end.
The Valve for aerocyst of described bar shaped hoisting air chamber can be arranged on the corner location of air bag head end.
The air bag head of described bar shaped hoisting air chamber is rectangular.
The air bag head of described bar shaped hoisting air chamber is triangular in shape.
The material of described bar shaped hoisting air chamber is rubber or kiss-coating cloth or kiss-coating cord fabric or plastics or coating material.
Described bar shaped hoisting air chamber is the version that skeleton is arranged, framework material can adopt the cord fabric of chemical fibers such as nylon, terylene, or steel cord or glass fibre, carbon fiber, bar shaped hoisting air chamber can use above-mentioned material a kind of material wherein, also can unite use by two or more materials.
Owing to make, to shrink as moulding or sulfuration, the meeting that the cross section of the air bag body of described bar shaped hoisting air chamber and air bag head transition phase has is milder arc.
Described bar shaped hoisting air chamber is operation for convenience, in the both sides of air bag head and air bag body a plurality of handles is set.
Beneficial effect
The flats structure of bar shaped hoisting air chamber of the present invention, because the height of air bag is between 10～150mm, there is not direct relation with the width of air bag, the air bag width is wide more, load-carrying ability is big more, but no matter the height of air bag can unlike columniform air bag, be not conical or hemispheric head construction greater than 150mm all the time, the air bag diameter is big more, its head projection high more, high more to the space requirement below the member of desiring lifting, be difficult to this air bag fill in member below.Even the space below the member of desire lifting is narrow and small, bar shaped hoisting air chamber of the present invention also can be placed on the inside easily, operates very laborsaving.
The bar shaped hoisting air chamber of flats structure is after inflation, and air bag head cross section ovalize is the wedge shape of convergence gradually to head end from the capsule body; When giving the airbag aeration bearing load, the cross section of air bag body is Long Circle, bigger than existing cylindrical air bag area of thrust surface, also the phase strain is big for its application force, each position of air bag is stressed evenly, the operating air pressure of air bag can reach 3MPa, and every meter load-carrying ability of air bag can reach more than 450 tons, and the load-carrying ability of wall scroll bar shaped hoisting air chamber can reach thousands of tons of; In when inflation, because the leading edge deformation of bar shaped hoisting air chamber is little, be the wedge shape of convergence gradually to head end, thereby the air bag head can not cause damage because of with the weight bottom friction taking place from the capsule body, guarantee the safety of member lifting.
