The device that extraction thieff hatch is blocked belongs to coal mine equipment field.More particularly to after a kind of closure, without removing, you can into
The plugging device of row methane gas extraction.
Background technology
Currently, in coal mine field, often needing to drill to coal seam and gas accumulation region carries out coal mine gas drainage, to prevent
The generation of the safety accidents such as gas explosion, Gas Outburst, usually first to coal bed drilling, drilling is connect when carrying out gas pumping
Extraction is carried out in dedicated pipeline, connecting tube is usually first placed in hole by the connection of drilling and pipe special, is completed installation and is fixed
Carry out the connection of pipeline again afterwards, usual engineering construction has certain period, and the laying time of usual dedicated pipeline is more long, connection
It needs first temporarily to be blocked after the completion of pipe installation is fixed, largely be oozed out to prevent methane gas, then beaten again when piping connection
It opens, when connection operation, needs operating personnel to be swift in motion, and is sprayed to prevent excessive gas, when the temporary plugging time is longer, hole
Interior pressure becomes larger, and the case where being sprayed outside methane gas is susceptible to when removing plugging part, so that operating environment is deteriorated, influences operation people
Member's health, using effect are bad.
Invention content
In order to improve the above situation, a kind of coal mine gas drainage thieff hatch plugging device of the utility model provides a kind of envelope
After stifled, without removing, you can carry out the plugging device of methane gas extraction.It can effectively prevent leaking when gas pumping.
A kind of coal mine gas drainage thieff hatch plugging device of the utility model is realized in：A kind of coal of the utility model
Mine gas pumping thieff hatch plugging device is made of main body plugging device and communication apparatus, and main body plugging device is by pivoted housing, limit
Plate, snap ring, expansion tube, screwed pipe and throw-out collar composition, expansion tube are placed on screwed pipe, and spiral shell is equipped on the expansion inside pipe wall

It holds to the other end and gradually increases, snap ring is placed on screwed pipe one end, is placed on screwed pipe in the middle part of limiting plate, and another with throw-out collar
End is connected, and pivoted housing is placed on screwed pipe one end, through-hole is provided on the pivoted housing, and be connected with screwed pipe, in the pivoted housing
Screw thread is equipped on wall, communication apparatus is by connecting rod, fixed plate, fixed link, fixed spring, sliding shoe, push rod, slip ring, fixation
Set, sliding slot, piston and connecting plate composition, slip ring are placed in pivoted housing, and the slip ring slidably, is opened on the screw thread inside pipe wall
There are sliding slot, sliding shoe to be placed in the sliding slot on screw thread inside pipe wall, is opened on the sliding shoe there are two connectivity slot, fixed spring is placed in
In sliding slot, described fixed spring one end is connected with sliding shoe, and the other end is connected with screwed pipe, and piston is placed on sliding shoe
In connectivity slot, fixed link one end is placed on piston, and fixed plate one end is placed on the fixed link other end, and the other end is placed in screwed pipe
On wall, push rod one end is placed in the middle part of sliding shoe, and the other end is placed in slip ring, and fixing sleeve is placed on the push rod other end, and logical
Two connecting rods are crossed with slip ring inner ring to be connected.
In use, when being blocked to coal mine gas drainage thieff hatch, expansion tube is put into thieff hatch first, makes to turn
It is sleeved on outside thieff hatch, then rotates pivoted housing, pivoted housing drives rotated threaded tubular, screwed pipe and expansion tube screw-thread fit, and then screw thread
Pipe is to expansion in-pipe, and screwed pipe drives throw-out collar to expansion in-pipe, and the outer diameter of the throw-out collar is from one end to another
End gradually increases, and then throw-out collar makes expansion tube swelling, expansion tube and thieff hatch hole wall fit closely, and progress is stuck, and then completes
Closure to drainage holes screws in extraction pipeline in pivoted housing when carrying out gas pumping, and extraction pipeline pushes slip ring, sliding
Ring slides in pivoted housing to screwed pipe direction, and then slip ring pushes push rod into screwed pipe by fixing sleeve, and push rod, which pushes, to be slided
Motion block, sliding shoe slide in sliding slot, and fixed spring is compressed, and then keep two pistons sliding out of corresponding connectivity slot respectively
Go out, and then two on sliding shoe connectivity slot is opened, methane gas enters in screwed pipe, then passes through two on sliding shoe
Connectivity slot flows into pivoted housing, finally flow into extraction pipeline, realizes methane gas extraction, reaches and is used on coal mine, to gas
The purpose that extraction thieff hatch is blocked.
Advantageous effect.
One, simple in structure, it is convenient and practical.
Two, cheap, it is easy to spread.
Three, it can effectively prevent leaking when gas pumping.
