Abstract
The invention discloses a ventilatorduct, one end of each section of the ventilatorduct is provided with a steel ring, and the other end thereof is provided with a rope, the end provided with the rope of the next section of the ventilatorduct is sheathed at the end provided with the steel ring of the previous section of the ventilatorduct with an overlapped part; the overlapped part is tied with a tightening strap, the tightening strap is pressed on the steel ring, two ropes of the tightening strap are respectively positioned at two sides of the steel ring; after the two ropes are strained and locked, two sections of the ventilatorducts are butt-jointed together tightly by the tightening strap, the joint is tight and not easy to leak air, and firm and reliable. The ventilatorduct of the invention is not provided with a double-reverse edge structure, is simple, fast, and labor-saving when replacing the wind cone, the replacement can be completed quickly without stopping the air blower or affecting the wind supply of the tunneling working surface. The air leak caused by the distortion of the extruded steel ring of the ventilatorduct can be handled simply without much effort due to no double-reverse edge structure. Each section of the ventilatorduct of the invention is only provided with one steel ring, thus reducing the manufacturing cost.
Description
Technical field:
The present invention relates to the ventilation equipment in down-hole or tunnel, relate in particular to vent wind cone.
Background technology:
In the construction of the driving production of down-hole or tunnel, need in down-hole or tunnel, blow by air duct, the more piece air duct forms the air channel by butt joint fresh air is sent into the shaft bottom.Each saves the butt joint of air duct should be tight, and changing the operation that air duct or processing leak out should be simple.Air duct of the prior art, the two ends of every joint have steel ring, and have the flanging part, 2 joint air ducts whens butt joint, with the steel ring of a joint air duct overlap save air duct after, the flanging that saves air duct is turned back, more equitant two flangings while reflexed is returned.Along with the extension of air duct, increasing near the air duct internal pressure of blower fan, the situation of leaking out often appears in the joint of two joint air ducts, even air duct is blown open.More than two anti-limits formula air duct docking mode, when processing is leaked out, need two anti-limits are opened, again the limit backspace is gone after handling, not easy to operate; When air duct need be changed, not only need to open two anti-limits, but also two diameter steel rings identical and that be nested together will be taken away, overlap the operation on steel ring and two anti-limits after the replacing again, waste time and energy very much, operation is difficult more under the situation that does not stop blower fan.If stop blower fan, then should the personnel of withdrawing from suspend production, in the actual production, the workman often operates against regulations, and promptly stops blower fan under the personnel's of not withdrawing from situation, carries out air duct and changes or handle the operation of leaking out, gas density in the mine transfinites and very easily causes and production accident have potential safety hazard.
Summary of the invention:
The object of the present invention is to provide a kind of leakproofness of docking to be difficult for leaking out, handling the simple and quick vent wind cone that leaks out and change air duct well.
Vent wind cone of the present invention, an end of every joint air duct has steel ring, and the other end is installed with rope, and the rope ends of following joint air duct is enclosed within on the steel ring end of joint air duct, and an overlaid part; At described overlapping bundle clamping band is arranged, be installed with two ropes in the described clamping band, two ropes are isolated mutually, and clamping band is pressed on the steel ring of described overlapping, and two ropes lay respectively at the both sides of steel ring; Each bar rope ends has snap close.
The cord lock fastener has two rings, and two rings are nested, and an end of rope is fixed on the ring, and the other end overlapped the another ring, passes from described last ring.
The suspension ring of vent wind cone are annular, and described suspension ring have knot that can be undone by a pull.
Air duct docking facilities of the present invention, after two rope stretches of clamping band and the pinning, clamping band just is docking together two joint air ducts tightly in the steel ring position of last joint air duct, and joint is tight, is difficult for leaking out.The present invention does not have the structure on two anti-limits, when changing wind sleeve, unclamps the rope snap close, and it is promptly replaceable to take off clamping band, and simple and fast, laborsaving just can be finished under the situation that does not stop blower fan very soon, can not influence the air feed of driving face.Leak out if the air duct steel ring is extruded to be out of shape to cause,, raise one's hand just can handle, simple leicht fallen D/A owing to there is not two anti-limits structure.Rope snap close of the present invention can not relaxed voluntarily, can only be more and more tighter along with heaving of air duct.Air duct suspension ring of the present invention be difficult for to break off relations, and have overcome original S shape suspension ring and have easily broken off relations, and make air duct directly not influence air feed or air duct to land the drawback of damaging air duct because of the part suspension ring break off relations.The every joint of air duct of the present invention has only a steel ring, has reduced manufacturing cost.
Description of drawings:
Fig. 1 is single air duct structural representation among the present invention.
Fig. 2 is clamping band structural representation among the present invention.
Fig. 3 is an air duct docking structure schematic diagram of the present invention.
Fig. 4 is a cord lock buckle structure schematic diagram.
Fig. 5 is air duct suspension ring structural representations.
The specific embodiment:
As shown in Figure 1, an end of air duct has steel ring 1, and the other end is installed with rope 2, and rope 2 two ends have snap close 3.As shown in Figure 2, be installed with two ropes 2 in the clamping band, twine mutually for preventing rope, two ropes are kept apart, this example has adopted the mode of rolling a line 4 at clamping band longitudinal midline place that two ropes are isolated, and also can adopt other isolable modes.Shown in Fig. 3 air duct docking structure schematic diagram, arrow points is a wind direction, and 5 is last joint air duct, and 6 for saving air duct down, and 7 is clamping band.With the operating procedure of air duct butt joint be: rope ends 62 covers that, will save air duct 6 down upwards save the steel ring end 51 of air duct 5, and the rope of the rope ends 62 of tension air duct 6, and fasten the rope snap close, but can not tension reaches air duct and do not blown open and get final product.Two, adjust air duct 6, make a upper and lower joint air duct joint overlaid part 8, in this example the about 6-8 of lap centimetre.Three, at air duct 5,6 butt joint overlappings, clamping band 7 is pressed on the steel ring 51, makes two ropes 2 of clamping band lay respectively at steel ring 51 both sides, the tension rope also locks the snap close of rope, and air duct 5,6 just has been docking together tightly.Under the situation that does not stop blower fan work, also can fast finish air duct expediently and change docking operation.When interface leaks out,, raise one's hand just can handle owing to not having two anti-limits structure, only need directly filler being filled out at the place of leaking out gets final product.
As shown in Figure 4, the cord lock fastener has 9,10, two rings of two rings to be nested, and an end 11 of rope is fixed on the ring 9, and the other end 12 overlapped and encircles 10 and pass from encircling 9, and the rope other end 12 makes two rings be nested after passing two rings just.Untie the rope other end 12 except that non-artificial, otherwise rope only can be more and more tighter along with external force.
As shown in Figure 5, the air duct suspension ring are annular, have knot that can be undone by a pull 13 on the suspension ring, after air duct is hung, the movable end 14 of suspension ring buckled in the knot that can be undone by a pull 13 get final product.These routine suspension ring can not break off relations.
