Abstract
The utility model discloses a continuous pull type air barrel sliding rail. The continuous pull type air barrel sliding rail comprises a group of sliding ways, and is characterized in that each sliding way is connected by virtue of a folding hinge; a group of hoisting rings is arranged on the upper side of each sliding way; and a group of pulley blocks is arranged in each sliding way. Compared with conventional movable dust exhausting fan and conventional method of continuously connecting dust exhausting air barrels, the continuous pull type air barrel sliding rail disclosed by the utility model has the advantages as follows: 1, the labor intensity of staff is reduced; 2, the time of continuously connecting the dust exhausting air barrels is reduced, so that the working efficiency is improved; and 3, the quantity of used dust exhausting air barrels is reduced, thus the cost is saved; the continuous pull type air barrel sliding rail plays a great role in controlling dust on the excavating working surface, improving the working condition of workers, increasing the excavating speed of a manual excavating surface, and preventing and reducing the generation of pneumoconiosis of the workers, so that huge society benefit, huge economy benefit and huge safety benefit are brought.
Description
Technical field
The utility model relates to a kind of air duct slide rail field, specifically, relates to a kind of continuous towed air duct slide rail.
Background technology
KCS-408zz dedusting fan 1150 kg that weigh, air duct adopts the negative pressure air duct of Φ 800mm, the long 5000mm of every joint, heavily about 100kg, manually move dedusting fan, receive dedusting air duct labour intensity greatly, inefficiency.So adopted dedusting fan is fixed on the method that moves forward with the advance of the face on the special frame at tail carrying section rear, the length of so just having fixed the dedusting air duct.In the driving face progradation, dedusting fan, air duct just must and work plane extend together.
The utility model content
The technical problems to be solved in the utility model provides a kind of continuous towed air duct slide rail, and the air duct of being convenient to the underground high-power dedusting fan is hung and automatically reach.
The utility model adopts following technical scheme to realize goal of the invention:
A kind of continuous towed air duct slide rail comprises one group of slideway, and it is characterized in that: described each slideway connects by folding, and the upside of described each slideway is provided with one group of suspension ring, is provided with one group of assembly pulley in the described slideway.
As the further restriction to the technical program, described each slideway two ends are ramp structure.
As the further restriction to the technical program, described assembly pulley comprises axle, and the two ends of described axle arrange respectively symmetrical totally-enclosed bearing, and the intermediate vertical of described axle is in the direction welding band iron of axle, and the lower end of band iron is provided with circular hole.
Compared with prior art, advantage of the present utility model with good effect is: the relative in the past traditional method of moving dedusting fan, receiving the dedusting air duct of the utility model, and the one, reduced worker's labour intensity; The 2nd, reduced the time of receiving the dedusting air duct, improved efficiency; The 3rd, reduced the use amount of dedusting air duct, saved cost.Dust for the control driving face improves workman's operating environment, improves the driving speed of tunneling working face, and playing an important role of prevention and minimizing workman pneumoconiosis brings huge society, economy and safety benefit thus.

Fig. 3 is that the A of Fig. 2 is to view.
Fig. 4 is the structural representation of chain link of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment the utility model is done further to describe in detail.
Referring to Fig. 1-Fig. 4, the utility model comprises slideway 1, folding 2, suspension ring 3, axle 4, bearing 5, band iron 6, circular hole 7, chain link 8, described each slideway 1 connects by folding 2, and the upside of described each slideway 1 is provided with one group of suspension ring 3, is provided with one group of assembly pulley in the described slideway 1.
Described each slideway 1 two ends are ramp structure.
Described assembly pulley comprises axle 4, and the two ends of described axle 4 arrange respectively symmetrical totally-enclosed bearing 5, and the intermediate vertical of described axle 4 is in the direction welding band iron 6 of axle, and the lower end of band iron 6 is provided with circular hole 7.
The design of slideway 1: in the tunneling construction process; because the variation of geological conditions; going up a slope or descending often can appear in the tunnel; in conjunction with the downhole production reality of work, adopt square steel pipe as slideway, every ramp design length is 3000mm; with lathe at the wider face opening of getting on the bus out; one side welding 5 suspension centres that suspension ring as slideway with back be connected relative with opening in use, can be chosen suspension centre according to the position of the roofbolt of constructing and hang.Inclined design is adopted at the two ends of slideway 1, so that slideway 1 can up-down adjustment after using folding 2 to connect.
The design of assembly pulley: adopt 202 totally-enclosed bearings as the wheel of assembly pulley, go out the axle 4 of assembly pulley with the reinforcing bar car, a dish 202 totally-enclosed bearings 5 are inlayed respectively at the two ends of axle 4, intermediate vertical at axle 4 is welded band iron 6 in the axle of assembly pulley, the other end of band iron 6 arranges circular hole 7, and air duct is directly hung on assembly pulley by this circular hole 7 and shackle (not shown) during use.
The design of folding: because the length of single slide rail is 3000mm; and the dedusting air duct total length that use the down-hole has reached 60m---75m; because in the tunneling process; often the gradient can appear; therefore every slideway must use folding 2 to connect in the slide rail use procedure; finely tune with the roadway gradient variation, guarantee that the dedusting air duct is relatively fixing apart from the distance of top, tunnel, base plate.
The design of chain link
Choose the chain link that length is 300mm, in the end welding M22 of chain link anchor rod nut (not shown), during use nut is connected with back anchor pole (not shown), the other end of chain link is connected with the suspension ring of slideway by the shackle (not shown), hangs highly and can regulate up and down by shackle.
Use flow process: when in use, first chain link is fixed on the roofbolt, again slideway 1 and chain link is connected, link to each other with folding 2 between slideway and the slideway, after slideway is fixedly connected with, assembly pulley is put into slideway, be connected with the air duct suspension ring according to the distance of one group of every 500mm.In tunneling process, when dragging tail, airborne dedusting fan moves forward with tail, close direction of meeting head on only need spur the front end of dedusting air duct forward gently and get final product, when the place ahead have enough apart from the time, at the slideway 1 of pulling down the rear end, receive the technique of receiving that front end has just been finished blower fan reach and whole dedusting air duct.
Certainly; above-mentioned explanation is not limitation of the utility model; the utility model also is not limited only to above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement also belong to protection domain of the present utility model.
