Abstract
The utility model discloses a convenient mining dryer of connecting is applicable to tunnelling working face head -on. A port inboard of every section dryer sets up a sealing washer, and the outside sets up the sealing strip of a nylon material, and another port department sets up two steel rings. When the dryer was connected, the pot head that has a sealing washer one was served what have the steel ring, makes it overlap one section each other, makes the sealing washer press between two steel rings. The sealing strip one end of nylon material is equipped with the steel dicyclo and detains, and the sealing strip presses the part between the steel ring to make two dryer abutting joint, and locking steel dicyclo is detained behind the taut nylon material sealing strip to the completion dryer is connected. The utility model discloses make dryer connection work simple accurate to the dryer simple structure, the headwork face of dryer need often be connected to the specially adapted.
Description
Technical field
The utility model patent relates to a kind of convenient mining ventilating tunnel connected.
Background technology
According to the regulation of " safety regulations in coal mine ", the coal of highly gassy mine, low gaseous mine High gas area and exceptions area and half coal petrography heading end air duct are apart from meeting head on to be not more than 5 meters, and this just may cause the air duct that to crumble when driving shot firing operation, and the air feed that causes meeting head on is not smooth; In addition, because driving face constantly advances, air duct connection must be carried out in time, and blower fan can not be made to suspend air feed, otherwise easily cause driving face gas density to transfinite, threaten safety in production.Thus, be necessary to improve the structure of air duct and connected mode, make air duct be easy to connect and inleakage is few, thus reduce potential safety hazard, guarantee safe production.
Current air duct connects the method mostly adopting the two-way back-pressure limit of forward grafting, there is steel loop at air duct two ends, the tension of duct-joint steel loop is locked, it prevents the technique come off from being: along air duct wind direction, air duct is inserted next joint air duct, tension connector, the steel ring of joint is made to be adjacent to lock jail, first strain along the anti-limit of air duct wind direction afterwards, anti-limit is compressed and connects steel ring, can not fold be there is, more anti-the anti-limit of air duct wind direction, return half, compress and connect steel ring, the back-pressure limit of steel ring both sides is wanted evenly.The method complicated operation and expending time in as can be seen from the above step.
Summary of the invention
Task of the present utility model is to solve the technological deficiency existed in existing air duct and air duct method of attachment, provides a kind of convenient mining ventilating tunnel connected, reduces inleakage.
Concrete solution is:
The convenient mining ventilating tunnel connected, often saving air duct one end is two steel rings, and the parallel distance between two steel rings is 5cm; Adhere to a circle foaming weather strip inside other end air duct, form sealing ring, sealing ring width is 4.5cm, the band of an air duct arranged outside nylon material, and width is 4.5cm, and band one end arranges a steel two-ring fastener.When carrying out air duct and connecting, the one end with sealing ring is enclosed within to be had on one end of steel ring, and sealing ring is overlapped with steel ring.Width due to sealing ring 0.5cm less of the width between two steel rings, so sealing ring is pressed between two steel rings, thus makes foaming weather strip seal up part between two steel rings completely.Then nylon material band is pressed in the sealing ring of the two joint air ducts part overlapping with between steel ring, one end of nylon material band has steel two-ring fastener, when band is locked, first band is passed from two rings simultaneously, open two-ring fastener again, then walk around short steel loop, band is worn from long ring, finally band is strained, complete air duct and connect.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail:
Fig. 1 is the structural principle schematic diagram of the utility model embodiment.
Fig. 2 is band part organigram.
1. leeward transportation work style cylinder, 2. windward transportation work style cylinder, 3. band, 4. steel rings in figure, 5. foam weather strip, 6. steel two-ring fastener.
Detailed description of the invention
By reference to the accompanying drawings 1, Fig. 2,
The convenient mining ventilating tunnel connected, comprise air duct body 1 and 2, the band 3 of the nylon material outside air duct 1 interface, the foaming weather strip 5 inside air duct 1 interface, the steel ring 4 of air duct 2 interface, the steel two-ring fastener 6 of band 3 one end forms.
Nylon material band 3 one end of this air duct interface has steel two-ring fastener.When carrying out air duct and connecting, leeward transportation work style cylinder 1 cover is in the wind on transportation work style cylinder 2, namely has one end of sealing ring to be enclosed within one end of steel ring, makes it an overlapping part, and foaming weather strip 5 is just in time nested between two steel rings 4.When then band 3 being locked, band is pressed on sealing ring, then band 3 one end is passed from two steel rings simultaneously, open steel two-ring fastener again, band 3 is walked around short steel loop 61, then rope is worn from long ring 62, finally band 3 is strained, complete air duct and connect.
The relevant technologies content do not addressed in aforesaid way is taked or uses for reference prior art to realize.
It should be noted that, under the instruction of this manual, those skilled in the art can also make such or such easy variation pattern, such as equivalent way or obviously mode of texturing.Above-mentioned variation pattern all should within protection domain of the present utility model.
Claims (4)
1. the convenient mining ventilating tunnel connected, is characterized in that: often save air duct one end and arrange two steel rings, the parallel distance between two steel rings is 5cm, and the other end encloses in air duct inner adhesion one the foaming weather strip that width is 4.5cm; When air duct connects, the steel ring end of air duct is enclosed within the foaming weather strip end of air duct, and utilizes the steel two-ring fastener that the band of nylon material and its one end have, and is connected by two joint air ducts.
2. a kind of convenient mining ventilating tunnel connected according to claim 1, it is characterized in that: described nylon material band is positioned at one end of leeward transportation work style cylinder, and width is 4.5cm, one end of band is a steel two-ring fastener.
