Abstract
The utility model relates to a multi-ply pressure-proof hoisting air bag, which is enhanced by the cord fabric and has a valve communicated with the air source. The utility model can be used for the rescue reciprocating working and the lifesaving working of the rolling stock and applies to the install trade of the subway, the steel work, the power station, the mine, and the electromechanical device, which can also be used as the tool outfitting for hoisting and moving the heavy.
Description
The pneumatic Hoisting air bag that a kind of multilayer through compression molding is withstand voltage, air-tightness is good, be applicable to the rail vehicles accident rescue, play multiple operation, be specially adapted in the multiple operation of rising of narrow location, also be applicable to subterranean railway, steel plant, power station, mine and electromechanical appliance installation industry, also can be as lifting and the tool outfit that moves.
In the prior art, manual jack and hydraulic jack are used in lifting more, and the advantage of this metal jack is that load-carrying ability is big, but that shortcoming is a volume is big, because the rail vehicles scene of the accident is with a varied topography, narrow and uneven location can't be used.
The purpose of this utility model is to avoid above-mentioned shortcoming of the prior art and provides a kind of and can fill in the Hoisting air bag that uses as the lifting jack in the small gap very easily.
The purpose of this utility model can reach by following measure:
Hoisting air bag is strengthened cord, the second reinforcement cord, tire tube valve and face glue by inner bag, inner bag spacer (or separant), first and is formed.
Inner bag is to be made by full wafer rubber, has the sealing bag of good air-tightness, and inner bag can be made with natural rubber or neoprene.Place spacer in the middle of the inner bag or charge into separant, spacer can be a plastic tab, and separant can be silicone oil, french talc.Inner bag has first to strengthen cord outward, and second strengthens cord, coats, and strengthens cord and is formed by cord dipping, and cord can be the ultimate fibre synthetic material, also can be the multifilament synthetic material, also can be polyamide fiber material, also can be bundled steel wires.These materials can be imbedded in certain rubber, and with the keeping parallelism trend, cord can be the tow fabric that does not have intersection.Wirecord fabric can be a laid fabric.The layout of cord should guarantee that higher intensity is all arranged on all directions, for the whole plane that makes airbag all has isotropic mechanical property, need each layer cord to be intersected 90 ° mutually, orthogonal thereto overlapping placement.And at the cord two ends folded mutually place, should guarantee 80 ° the lap of splice at least along airbag length or Width.Like this, in the inner bag outside, each side has three layers to strengthen cord, and the horizontal and vertical intensity of airbag is equated.The junction of on airbag, going to the bottom, around inner bag, arrange liner, the material of liner is identical with the cord material, because of cord is a capwise at the airbag edge, liner is overlapped by line of force direction and cord along airbag, or around cord, increasing by a circle liner, the cord trend of circle liner is moved towards orthogonal thereto layout with the liner cord, forms the edge enhancement Layer.Tire tube valve is contained in the corner of air bag structure, tire tube valve can be that brass is made, the one end is extended to outside the airbag by airbag corner, so that join with external source of the gas, the other end passes cord and reaches in the inner bag, the end of tire tube valve can be securely when sulfidization molding bonds together with the cord of arranged crosswise, forms complete framing member.The outside of strengthening cord is covered by face glue, and face glue is formed by the poly-chloroprene rubber mold pressing, for making its surface good antiskid capability is arranged, and is shaped on the grid decorative pattern on face glue surface, constitutes Hoisting air bag.
Hoisting air bag can be made square, rectangle, cylindrical or pincushion.
The utlity model has following advantage: this airbag only has several cm thicks when unaerated, can fill in easily in the very little slit and use as the lifting jack, because the big pressure of airbag area of contact is little, so can use in floor, sloping floor, soft terrain and ice and snow environment, this is that ordinary jack can't be accomplished.
The drawing explanation of accompanying drawing:
Fig. 1 is the square airbag birds-eye view of Hoisting air bag embodiment
Fig. 2 is tire tube valve and the structural representation of strengthening cord
Fig. 3 is square air bag structure figure: along the X-X cutaway view
Along the y-y cutaway view
Among the figure: (10) inner bag, (12) spacer or separant, (14) first are strengthened cord, (16) second and are strengthened cord, (18) spacer block, (20) insertion ring, (22) face glue, (30) tire tube valve.
The utility model is further described below in conjunction with (accompanying drawing) embodiment:
Inner bag (10) is the airtight bag of being made by the full wafer sheet rubber with good air-tightness, inner bag (10) can be made with natural rubber or neoprene, place spacer in the middle of the inner bag (10) or charge into separant (12), spacer can be a plastic tab, separant can be a silicone oil, french talc, inner bag has first to strengthen the cord and the second reinforcement cord coating outward, strengthen cord (14,16) form by cord dipping, cord can be the ultimate fibre synthetic material, also can be the multifilament synthetic material, also can be polyamide fiber material, it can also be bundled steel wires, these materials can be imbedded in certain rubber, become to strengthen cord (14,16), cord can be a laid fabric, and wirecord fabric is a laid fabric.Need to strengthen cord (14) and the second reinforcement cord to first like this and intersect 90 ° of overlapping placements of quadrature mutually, and when each layer cord passes through two relative perimeter edge, cord overlaps each other, amount of lap is not less than 80% of perimeter edge, in inner bag (10) outside, each side has at least three layers to strengthen cord, and the trend of the second reinforcement cord (16) moves towards orthogonal thereto with respect to the first reinforcement cord.Junction, the end about airbag, arrange liner (18) all around along inner bag (10), the material of liner (18) and cord (14,16) material is identical, liner (18) lateral arrangement in the airbag perimeter edge, it and the first reinforcement cord (14) that passes through circumference, the second reinforcement cord (16) is orthogonal thereto, or along airbag perimeter edge increase by one circle liner (20), circle liner (20) cord trend is moved towards orthogonal thereto layout with liner (18) cord, form the edge enhancement Layer, tire tube valve (30) is contained on the turning of airbag, and tire tube valve (30) can be that brass is made, the one end is protruding in the outside, airbag turning, so that connect source of the gas.The tire tube valve other end can be securely when the airbag sulfidization molding bonds together with the cord (14,16) of arranged crosswise in inner bag (10), forms complete framing member.Strengthen cord (14,16) outside and covered by face glue (22), face glue (22) is formed by the poly-chloroprene rubber mold pressing, has good antiskid capability for making its surface, is shaped on the grid decorative pattern on face glue (22) surface, constitutes Hoisting air bag.
