Contiguous wave troughs are sealed together. Each cylinder bag is formed by fiber textile fabrics of rubber films with light weight, which are sealed. The utility model has compact structure, light cylinder body weight, convenient use and labor saving and time saving in operation. Compared with the existing air cylinder in a fixed type, the utility model has free expansion and contraction and can effectively guarantee air distances in a short time and obviously increase the service life and the work efficiency to enable the producing operation to be safer.
Description
Technical field
The utility model relates to a kind of device that ventilates when being used for tunnelling, particularly a kind of telescopic type air duct.Be applicable to that tunneling ventilations such as total rock lane, colliery, half coal rock tunnel, full coal rock tunnel, tunnel use.
Background technology
At present, during for various tunnellings such as total rock lane, colliery, half coal rock tunnel, full coal rock tunnel, tunnels, generally all adopt forced ventilation.Used air duct respectively save cylindrical shell by the hanging the tube bag that the glass fabric of rubber makes with the two sides and constitute of stationary magazine creel frame and Bao Lvqi periphery, its cylindrical shell weight is bigger, each saves cylindrical shell, and to articulate operation very inconvenient.
Stipulate according to safety regulations in coal mine: total rock tunnel, colliery wind distance must not be greater than 12 meters; Alternate heading wind distance must not be greater than 7 meters; Full coal petrography tunnel wind distance must not be greater than 5 meters.When its reason just is that the wind distance is excessive, the face air volume deficiency, pernicious gas can not in time be got rid of, and occurs methane accumulation easily, is unfavorable for safety in production; When the wind distance was too small, face air volume was excessive, and the dust with work plane blows afloat easily, and Dust Capacity is transfinited, and does not meet the regulation of safety code.The cylindrical shell of existing air duct is fixed, and wind is apart from adjusting, and every joint cylindrical shell weight is big again, therefore, for the joint of guaranteeing to construct apoplexy, every joint cylindrical shell have to be made as required to be about different sizes such as 10 meters, 5 meters, 3 meters, 2 meters apart from not transfiniting long.The back dense smoke of blowing out disperses, and before the joint length that requires according to reality is articulated in former cylindrical shell with required cylindrical shell, ventilates; When blowing out once more, should save cylindrical shell earlier and take,, be broken but still keep away unavoidably sometimes in order to avoid the rubble that is splashed is broken.This method of operating was both taken a lot of work, was required great effort, and had increased operating personnel's labour intensity, can't realize again guaranteeing the wind distance at short notice, brought hidden danger to safety in production.
The utility model content
The purpose of this utility model provides the mining air duct of a kind of telescopic type, its compact conformation, cylindrical shell is in light weight, easy to use, operation saving of labor, laborsaving compares with existing fixed formula air duct, it is capable of expansion and contraction, can effectively realize guaranteeing the wind distance at short notice, significantly improve its application life and operating efficiency, make production operation more safe and reliable.
The purpose of this utility model is achieved in that this device comprises skeleton and tube bag, its technical essential is: hang over the cylindrical shell of suspention on the line and constitute by preceding cylindrical shell, middle cylindrical shell with transition cylindrical shell three parts that fixing air duct joins, the tube bag of forming the each several part cylindrical shell is corrugated and distributes, each crest is encapsulated on the support frame that matches with its peripheral shape, adjacent trough is sealed, and the tube bag is formed by the sealing-in of lightweight glued membrane fibrous woven cloth.
The air opening end of cylindrical shell is provided with the movable catch of regulating before above-mentioned.
The shape of the end support skeleton of above-mentioned transition cylindrical shell and tube bag thereof is identical with the shape of the fixing cylindrical shell port of export of air duct.
Because the utility model employing is the tube bag of corrugated distribution and encapsulates the support frame composition cylindrical shell of its crest periphery, and hang on the suspention line with the preceding cylindrical shell of cylindrical shell, middle cylindrical shell with transition cylindrical shell three parts that fixing air duct joins, select for use lightweight glued membrane fibrous woven fabric width to be connected into the tube bag, so cylindrical shell is in light weight, during along the telescopic moving of suspention bobbin thread direction, operation saving of labor, laborsaving.This telescopic type air duct articulates, moves all very convenient when using, compare with existing fixed formula air duct, its extendable room is big, mobile freely, can not only effectively realize guaranteeing at short notice the wind distance, alleviate operating personnel's labour intensity, and can avoid the rubble that cylindrical shell is splashed to break, and significantly improve its application life and operating efficiency, make production operation more safe and reliable.

Specific implementation method
Describe the concrete structure of the present utility model and the course of work in detail according to Fig. 1-7.This air duct comprises the preceding cylindrical shell 2 that hangs on the suspension line 1, middle cylindrical shell 3 and transition cylindrical shell 4 three parts of joining with fixing air duct.Wherein the each several part cylindrical shell is assembled into by a plurality of support frames 6 and more piece tube bag 7 respectively, and the length of each several part cylindrical shell is looked the air-conditioning requirement of work plane and selected.Specification, shape and the quantity of each support frame 6 and tube bag 7 should be determined according to the cylindrical shell actual needs, make annulus body or polygonal body.The tube bag 7 of cylindrical shell is corrugated and distributes, and each crest of tube bag 7 is encapsulated on the support frame 6 that matches with its peripheral shape, and adjacent trough is sealed, and tube bag 7 is formed by the sealing-in of lightweight glued membrane fibrous woven cloth.Preceding cylindrical shell 2 is this air duct pith, at its air opening end the movable catch 8 of regulating is set, to regulate the caliber size of air duct outlet.During the air duct operate as normal, movable adjusting catch 8 turns up and disperses to be fixed on the cylindrical shell periphery, makes the bore of air duct outlet become big; Position beyond air duct need be retracted to the rubble bombardment scope of splashing when blowing out is unclamped the activity that is fixed on the cylindrical shell periphery and is regulated catch 8, it is closed up link together, and the bore of air duct outlet is diminished.Flow one timing of wind in air duct, the bore of air duct outlet is more little, and the flow velocity of wind is big more, and the apoplexy of can guaranteeing to construct makes work plane that enough air quantity be arranged apart from not transfiniting.For the transition cylindrical shell 4 that makes this air duct and fixing air duct (not shown) close proximity are fixed, the shape of its end support skeleton 6 and tube bag 7 thereof is identical with the shape of the fixing cylindrical shell port of export of air duct.
During use, the suspension ring on preceding cylindrical shell 2, middle cylindrical shell 3 and transition cylindrical shell 4 three parts are all hung on same the suspension line 1.Suspension line 1 front end ties up on the top net or anchor pole in tunnel, so that the air duct front end places in the wind distance of regulation.When work plane will be blown out, unclamp the activity that is fixed on the cylindrical shell periphery and regulate catch 8, it is closed up link together, make work plane that enough air quantity be arranged.Meanwhile, the air duct retraction beyond being in rubble bombardment scope, is ended preceding cylindrical shell 2.After blowing out, dense smoke disperses, and movable adjusting catch 8 is turned up disperse to be fixed on the cylindrical shell periphery, and the wind that can at short notice the air duct elongation be positioned at regulation up to preceding cylindrical shell 2 ends apart from part, ventilates.
