Description

SUMMARY OF THE INVENTION The present invention provides a mine-shaped inflatable cushion consisting of a textile shell coupled to an airtight bladder, mounted on a shaped structure, which consists of a central hollow cylinder with rectangular flanges fitted with valves and an eye. to which the pressure buffers are insulated in an air-tight manner and form a spatial body.

It serves as a working platform during reinforcement and maintenance, as a protective platform against falling objects, for hermetic closing of chimneys and as a shifting ramming for concrete walls of chimneys.

So far, mine inflatable cushion pillows have been produced abroad to close pits and chimneys for maintenance. They are made by single-layer vulcanization from overlapped rubberized fabrics. The vulcanization is carried out in steel molds - or in the shape of hoofs. Curing of the overlapped rubber foils or rubberized fabrics is accomplished by thermal vulcanization. The disadvantages of inflatable cushions of iv-ulfcanized rubber or rubberized fabrics are their high weight, high manufacturing effort in overlapping, forming and vulcanizing. Due to the high labor demand, the import of a large amount of raw materials and the high consumption of thermal energy in the vulcanization, the rubber inflatable vane is highly expensive. Also, the single-purpose characterizing device itself is a very expensive investment. A further drawback of the above-mentioned inflatable pillows is that they are not provided with retaining lugs for the possibility of joining the two bricks and the multiple vanes one above the other. Another drawback is that the van cushions are not provided with an apron that prevents water from flowing down the pillows into the center of the chimney profile where the assembly crews operate.

According to the invention, the above-mentioned drawbacks are solved by a banana inflatable cushion with a shaped structure which allows the closure of the mine chimneys. It serves as a sliding guard platform against falling rock and water fragments. It serves as a movable work platform for the raising, lowering and other work in vertical and inclined mining works. It serves as a sliding inflatable formwork for concreting mine chimney walls, while the sliding-inflatable formwork serves at the same time as a working platform. Mine inflatable cushions with shaped fcoinstruments can also be used in non-mining operations, for example in building blocks and benches.

The essence of a mine-shaped inflatable cushion with a shape composite consists in that it consists of an air-tight polyviinyl chloride bladder inserted and glued into a sewn textile cover. The textile-coated tube is twisted between the flanges of the molded structure and the pressure rings, which guarantee the air-tightness of the fabric. The flanges of the flanges form an unchanging skeleton of the vanicus even when the air pressure is reduced. In the flanges of the molded structure are fixed inlet valves and safety valves set at n- and op-temporal overpressure. For the flanged shape I-instructions, which simultaneously serve as non-variable parts of the p-racial and angular platform, the metal eyelets are also clamped, by means of which the mines of the inflatable rope and the pillows are suspended and mutually they stick together over themselves. The metal eyelets when the handles serve at the same time to engage the deflection pulley for conveying the material to the flue or the flange. they serve to provide stair ropes for workers working in the chimney.

An important advantage of the mine blower van is the hollow cylindrical shape, through which technological equipment can be passed, such as air hoses, telephone and electric lines, conveying hoses for concrete mixtures, ventilation of the worker, water drainage etc.

For pecker-mashing-weights, respectively. maintenance of the chimney is of considerable importance - the possibility of connecting low-olives - mine inflatable - pillows - with a shaped structure, in several mounting assemblies one above the other. The mutual connection is carried out by suspension ropes, respectively. and pulls the hinged eyes. The filling and suction of the inflatable vents are effected by switching the filling valves by means of a hose.

For added safety, the inflatable cushions can be joined to each other by means of textile straps to the steel rings. It can additionally protect against the fall of sharp objects on the top of the textile base by a thick fabric coated with a PVC layer, a wood removable grid or a rubber fabric. A textile apron sewn against the flow of water in the mine workpiece and its walls is provided by an inflatable vanicus which directs the stagnant water to the other side of the chimney wall.

A great advantage of the invention is that the inflatable cushion is of a structural design in the design of a slightly prolonged rivals on the diameter of the chimney reinforcement. j. With a diameter less than the diameter of the chimney itself, the depth of the reinforcement walls, it is possible to use both the inflatable sliding inflatable form and the working platform at the same time. The concrete grains for concreting the walls along the perimeter of the inflatable vanicus are pumped through a hose from a cylindrical shape structure - a protective inflatable platform - a cushion with a shape structure, respectively. The hollow cylindrical in-air β-racial β-platform can also be used as an inflatable formwork.

The design and solution of a mine-shaped pillow with a shape according to the invention is, compared to the known solutions, significant economic, without investment equipment in its production. It allows multiple-use and multipurpose use mainly with rewards by not making prospective and more productive technologies for reinforcement, maintenance and other work in mining boxes and pits.

In the accompanying drawing, a schematic representation of a mine inflatable cushion with a shaped structure according to the invention is shown.

In FIG. 1, the inflatable cushion with a shaped structure is formed by a bladder 9 made of polyvinyl chloride film which is inserted into the textile sheath 8. The airtight bladder 9 is connected to the textile sheath 8 by a two-component adhesive so that they both form. solid pneumatic cushion. The bladder 9 with the textile sheath 8 is airtightly connected with its rubber seals together with the rubber seals between the fasteners of the shaped structure 2 and the thrust rings 3 by means of screws 7. The fasteners 2 with openings in the middle are fastened to the hollow barrel. In addition, the control valves 5 and the safety valves 6 are fastened to the flanges 2 by means of screws. The air hose from the filling device - air distribution is screwed onto the filling valve 5.
