Description
Technical field
This utility model relates to a kind of mining equipment, particularly relate to a kind of can water injection hole quick blocking long-armed to coal body carry out pumping water into coal coal body long-armed water injection hole packer be can be recycled.
Background technology
A large amount of coal dust and gas can be produced during coal mining operation, not only there is the hidden danger of blast, also serious harm
Mining operations personnel's is healthy, and coal mining personnel have become the group of people at high risk of China's pneumoconiosis, and driving face is topmost dirt seedbed.In recent years, coal-bed flooding is that domestic colliery is commonly used as a kind of more advanced dust prevention.During water filling, the quality of drilling and sealing effect directly determines the effect of water injection dust control.The sealing of hole mode of prior art is mainly three kinds: cement mortar method of pore sealing, polyurethane method of pore sealing and stopper method of pore sealing.Cement mortar method of pore sealing labor intensity is big, sealing of hole weak effect, inefficiency, polyurethane method of pore sealing sealing of hole intensity is little, sealing of hole apart from short, easily there is gas leakage, therefore stopper method of pore sealing becomes commonly used water injection dust control method.The coal seam flooding hole sealing device of prior art, its inner tube is generally steel pipe, the outer tube two ends of quality of rubber materials and fastener for connection, when high pressure is filled, rubber outer tube generation elastic deformation, it easily ruptures with the connecting portion of steel pipe, cause stopper to be damaged, improve operating cost simultaneously.
Summary of the invention
It is an object of the invention to provide a kind of can water injection hole quick blocking long-armed to coal body carry out the long-armed water injection hole packer of coal body of pumping water into coal, to achieve these goals, the technical scheme is that the long-armed water injection hole packer of coal body, including main body tube, it is characterized in that: main body tube left end is provided with floral tube, back seat annulus it is installed with on the right side of floral tube, annulus extruding disk it is movably installed with on the right side of back seat annulus, it is wound with the rope made of hemp between back seat annulus and annulus extruding disk, the main body tube being wound around the rope made of hemp is outer with Saint Andrew's cross decorative pattern, it is movably installed with transition conduit on the right side of annulus extruding disk, parbuckle screw is installed on the right side of transition conduit, the right-hand member of main body tube is provided with change head, become and be provided with car silk between head and parbuckle screw, parbuckle screw coordinates with car silk.
The long 300mm of described floral tube, main body pipe range 1800mm, car filament length 400mm, a diameter of 50mm of annulus extruding disk, a diameter of 50mm of back seat annulus.
The described diameter after the winding rope made of hemp is less than annulus extruding disk or the diameter of back seat annulus.
Moisture enters coal body, release part gas, effectively reduce coal gas content, after water filling reaches effect, dust more than 80% can be reduced, improve workman's working environment, stop dust explosion accident, moistening coal body, reduce priming system, reduce cost, increase the security of workman, after using run before to exhaust to drill a hole to add work surface drainage system, bleeder off hole gas emission and the quiet amount of bracelet significantly increase, play preferable protrusion-dispelling effect, effectively release crustal stress, gas pressure, stop to highlight during coal cutting the generation of accident；Solve coal cutting ore deposit and gas exceeding limit problem time protrusion-dispelling is drilled, can effectively prevent coal, Gas Outburst and blast.
The present invention is with low cost, and construction easy to make is simple.

Detailed description of the invention
Long-armed water injection hole packer is made up of water injection pipe and plugging device two large divisions.
It is to connect long-armed water filling water inlet pipe that long-armed water injection hole packer water injection pipe mainly completes function, and by long-armed water injection hole packer water injection pipe, coal body is carried out water filling.When long-armed water injection hole packer plugging device major function is water filling, water injection hole long-armed to coal body carries out sealing of hole, prevents water injection hole from leaking.
1, long-armed water injection hole packer water injection pipe is made up of 4 points of main body tubes and 4 points of change heads (connecting pumping water into coal water inlet pipe).4 points of main body tube total lengths 1.8m, end 300mm is 4 potted flower pipes, and to reach in hole the purpose to surrounding water filling, front end 400mm is 4 to be in charge of car silk, and welding is straight-through foremost.
2, long-armed water injection hole packer plugging device is made up of the plugging material (the predominantly rope made of hemp) in the middle of back seat annulus and annulus extruding disk and back seat annulus, annulus extruding disk, parbuckle screw, transition conduit.
During sealing of hole, by being wound to close to water injection hole aperture in back seat annulus, annulus extruding disk centre plugging material (the predominantly rope made of hemp), it is then placed in hole, by tightening parbuckle screw, transition conduit, annulus extruding disk are extruded, the rope made of hemp is made to be full of water injection hole by extrusion expansion, reach sealing of hole purpose, then connect water filling water inlet pipe, reach water filling purpose.During dismounting, by unloading parbuckle screw, make the plugging material release of pressure in the middle of annulus back seat, annulus extruding disk, be reduced to extract out less than behind aperture.
