Abstract
The utility model discloses a kind of mining seamless air duct, comprise cylindrical shell, cylindrical shell comprises barrel cover, steel ring; Barrel cover is from arranging outer covering layer, the first enhancement Layer, the second enhancement Layer and internal coated layer respectively outside to inside, and steel ring is between the first enhancement Layer and the second enhancement Layer; Outer covering layer seam areas forms ridge sideband in the first enhancement Layer upper end; Described ridge sideband is provided with several suspension ring mouths, suspension ring mouth is provided with riveting ring; Ridge sideband and the first enhancement Layer corner are bonded with triangle reinforcing band.The utility model structure is simple, assembles very convenient.The riveting ring that ridge sideband is arranged, can carry out assembly connection by the davit effectively and in hole, ore deposit, the triangle reinforcing band that ridge sideband and the first enhancement Layer corner are arranged, can firm ridge sideband, avoids lifting the corrupted caused for a long time.Barrel cover two ends are also provided with screen pack, even if make, after the multiple air duct of assembling, also tentatively to filter the air of coming in, improve the quality of air conveying in air duct.
Description
Technical field
The utility model relates to a kind of mining seamless air duct, belongs to mining equipment field.
Background technology
Because Climatic regionalization has become and gas, mine dust, water, the major natural disasters arranged of fighting, receive and adopted both at home and abroad
The common concern on ore deposit circle, the especially key subjects urgently to be resolved hurrily that face of China's coal-mine deep mining.For ensureing that downhole safety is produced, each mine main is all necessary for down-hole air-supply, and this just needs to use air duct.
Utility model content
For overcoming above-mentioned deficiency, the utility model object is to provide the simple and mining seamless air duct that can filter conveying air of a kind of structure.
Scheme of the present utility model is as follows: a kind of mining seamless air duct, comprises cylindrical shell, and described cylindrical shell comprises barrel cover, steel ring; Described barrel cover is from arranging outer covering layer, the first enhancement Layer, the second enhancement Layer and internal coated layer respectively outside to inside, and described steel ring is between the first enhancement Layer and the second enhancement Layer;
Described outer covering layer seam areas forms ridge sideband in the first enhancement Layer upper end; Described ridge sideband is provided with several suspension ring mouths, suspension ring mouth is provided with riveting ring, for lifting; Described ridge sideband and the first enhancement Layer corner are bonded with triangle reinforcing band;
Described barrel cover two ends are also provided with screen pack;
Described outer covering layer is plastic coat layer of cloth, and first and second described enhancement Layer is high-strength high-modulus polyethylene fiber enhancement Layer, and described internal coated layer is layer of PVC.
Further, described outer covering layer, the first enhancement Layer, the second enhancement Layer thickness proportion are 1:0.8:0.6:0.2.
Further, described triangle reinforcing band is made up of polyester canvas or duck material.
Further, the external surface of described outer covering layer is also coated with high temperature resistant gluing.
The utility model structure is simple, assembles very convenient.Several the utility model are coupled together, will use as a large-scale air duct.The utility model enhancement Layer adopts high-strength high-modulus polyethylene fiber, and its intensity is etc. 5 times of heavy steel wire, and have excellent pliability, resistance to chemical attack, resistance to explosion and cutting, also have fire resistance, compares traditional air duct skeleton, there is obvious advantage simultaneously.The riveting ring that ridge sideband is arranged, can carry out assembly connection by the davit effectively and in hole, ore deposit, the triangle reinforcing band that ridge sideband and the first enhancement Layer corner are arranged, can firm ridge sideband, avoids lifting the corrupted caused for a long time.Barrel cover two ends are also provided with screen pack, even if make, after the multiple air duct of assembling, also tentatively to filter the air of coming in, improve the quality of air conveying in air duct.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is schematic cross-section of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
A kind of mining seamless air duct, comprise cylindrical shell, cylindrical shell comprises barrel cover 1, steel ring 2; Barrel cover 1 is from arranging outer covering layer 11, first enhancement Layer 12, second enhancement Layer 13 and internal coated layer 14 respectively outside to inside, and steel ring 2 is between the first enhancement Layer 12 and the second enhancement Layer 13; Outer covering layer 11 seam areas forms ridge sideband 3 in the first enhancement Layer upper end; Ridge sideband 3 is provided with several suspension ring mouths 4, suspension ring mouth 4 is provided with riveting ring, for lifting; Ridge sideband 3 and the first enhancement Layer 12 corner are bonded with triangle reinforcing band 5; Barrel cover 1 two ends are also provided with screen pack 6.
Outer covering layer adopts plastic coat cloth material, and first and second enhancement Layer adopts high-strength high-modulus polyethylene fiber material, and internal coated layer is layer of PVC.Outer covering layer, the first enhancement Layer, the second enhancement Layer thickness proportion are 1:0.8:0.6:0.2.Triangle reinforcing band is made up of polyester canvas or duck material.The external surface of outer covering layer is also coated with high temperature resistant gluing.
The utility model satisfactory mechanical property, by test, pulls apart brute force through broadwise and is 2000N/50mm, be greater than 250N through broadwise tear edge.
Although give detailed description and explanation to detailed description of the invention of the present utility model above; but what should indicate is; we can carry out various equivalence according to conception of the present utility model to above-mentioned embodiment and change and amendment; its function produced do not exceed that manual contains yet spiritual time, all should within protection domain of the present utility model.
