Abstract
Provided is a movable type wind tube. The utility model belongs to the field of a ventilation of an underground construction and security. The structure of the movable type wind tube comprises a fixed wind tube (1), a movable wind tube (8) and a guide rail (7). The fixed wind tube (1) is movably connected with the movable wind tube (8) in a sealed mode. The movable wind tube (8) can be retractable inwards and outwards along the fixed wind tube (1). An air outlet of the movable wind tube (8) is connected with the guide rail (7) through a hanger rod (1). The movable wind tube (8) can move retractably along the guide rail (7). The problem that a slungshot damages the wind tube in the process of blasting of a working face is solved. After blasting, the movable wind tube can be pulled to a setting position through a rope reel machine, and therefore an air outlet of the wind tube (a press-in type) or an air inlet of the wind tube (an extraction type) can be arranged on the position where the distance to the wording face is not larger than an effective firing range of the air outlet of the wind tube ( the press-in type ) or an effective firing range of the air inlet of the wind tube ( the extraction type ), and therefore ventilating effects can be guaranteed. On the other hand, according to the movable wind tube, continuous ventilation can be carried out. The important aspects comprise that blasting fume can be diluted and removed fast, safety production can be guaranteed, and labor productivity can be improved.
Description
Technical field
The utility model relates to a kind of portable air duct, especially can prevent blasting flyrock to damage the portable air duct of air duct.Belonging to underground construction ventilates and security fields.
Background technology
The dead face driving of underground construction often will adopt booster to ventilate, and booster ventilates and usually is comprised of ventilation fan and air duct.That its draft type has usually is forced, pull-out type and hybrid etc.For the ventilation effect that obtains, air duct air outlet (forced) or intake (pull-out type) must be not more than effective range (forced) or the effective absorption distance (pull-out type) of air duct to the distance of work plane.But the distance of effective range (forced) or effective absorption distance (pull-out type) is all shorter, especially the distance of effective absorption distance (pull-out type) is shorter, and the casting distance of explosion time part slungshot is far away, and this just means that air duct unavoidably can be subject to the attack of slungshot.In order to make air duct avoid the infringement of slungshot, people often are installed in air duct the place away from work plane, have reduced widely ventilation effect, can't dilute quickly and effectively blasting fume, the dust of getting rid of work plane, have serious accident potential.Therefore, must take effective air duct safeguard procedures, improve the reliability that booster ventilates.The portable air duct that the utility model provides, the air duct that booster is ventilated exempts from the infringement of slungshot, does not affect ventilation effect simultaneously, guarantees safe production.
Summary of the invention
The utility model provides a kind of portable air duct.Before the explosion, will away from work plane, be positioned at safe place near the portable air duct of work plane, after the explosion, again it be shifted to work plane, the position of set positions.It can avoid the attack of slungshot, makes air duct exempt from damage, can carry out continuous ventilating again, ensures booster ventilation normal operation.It is simple in structure, and is easy to use.
The technical solution adopted in the utility model is: as shown in Figure 1, portable Wind cylinder structure is for comprising fixedly air duct 1, movable air duct 8 and guide rail 7, fixedly air duct 1 be connected air duct 8 air-tight movables and connect, movable air duct 8 can be along fixing air duct 1 inwardly to external extension, the air outlet of movable air duct 8 is connected with guide rail 7 by overhanging bar 10, and movable air duct 8 is along guide rail 7 telescopic movables.
Described fixedly air duct 1 outer cover has the fixedly air duct collar 3 that is connected and fixed the horizontal hanging stick 2 of air duct, and fixedly the horizontal hanging stick 2 of air duct is fixed on the wall 18.
As shown in Figure 4, the diameter of described fixedly air duct 1 is greater than movable air duct 8, movable air duct 8 is inserted in fixedly air duct 1, fixedly the edge of air duct 1 arranges interior to flange 19, the edge of movable air duct 8 arranges export-oriented flange 20, interiorly with export-oriented flange 20 corresponding positions packing ring 6 is set to flange 19, when enhancing activity air duct 8 moves or the sealing when static.
Described guide rail 7 internal constructions are the track with wheel 9, guide rail 7 is with fixedly air duct 1 is parallel with the axis of movable air duct 8, movable air duct 8 air outlet places cover has the collar 15, overhang bar 10 1 end retaining collars, an end links to each other with the main shaft of guide rail 7 inner wheels, as shown in Figure 3, guide rail 7 is fixed on the horizontal hanging stick 4 of guide rail by bulge loop 5, and the horizontal hanging stick 4 of guide rail is fixed on the wall 18.
Described overhanging connects steel cable 16 on the bar 10, steel cable 16 is walked around fixed pulley 12 and connected rope rolling 17, and rope rolling 17 is fixed on roadway floor 14, and fixed pulley is fixed on the wall 18 by the horizontal hanging stick 11 of fixed pulley.The unlatching of rope rolling 17 can be finished by audio-switch; When movable air duct 8 arrived desired location, rope rolling 17 quit work, and shutdown can be controlled with optoelectronic switch.
Before work plane 13 carries out bursting work, by promoting movable air duct 8 it is reduced to fixedly in the air duct 1, air duct is positioned within the safe distance; The sound that produces when explosion occurs triggers audio-switch, makes the rope rolling running, and movable air duct is drawn out, and behind the arrival desired location, shuts down.So just, can dilute rapidly the eliminating blasting fume, guarantee safe production.
The beneficial effects of the utility model are, before the explosion, portable air duct is retreated to safe position, slungshot is to the infringement problem of air duct when having solved the work plane explosion, can move movable air duct to desired location by rope rolling after the explosion, air duct air outlet (forced) or air intake vent (pull-out type) can be arranged in the place that is not more than its effective range (forced) or effective absorption distance (pull-out type) apart from work plane like this, guarantee ventilation effect.On the other hand, portable air duct can be carried out continuous ventilating, also is that dilution is got rid of blasting fume, guaranteed safe production the importance of raising labour productivity rapidly.The utility model is simple in structure, and is easy to use, easily safeguards.
