Description
Technical field
The utility model, which belongs to the distinguished and admirable regulation of underground coal mine fully-mechanized mining working upper corner, prevents gas accumulation technical field.
Background technique
In order to guarantee that coal mine downhole safety produces, underworkings and fully-mechanized mining working are equipped with perfect ventilating system,
Since gas specific gravity is lighter, and upper corner, close to coal wall and goaf side, airflow velocity is lower, and part is in turbulent state,
Gas is difficult to enter in main airstream, and fully-mechanized mining working upper corner is easy to gather gas, forms the gas exceeding limit problem of upper corner,
Safety in production is impacted.Gather to effectively administer fully-mechanized mining working gas at upper corner, it is general using in upper corner at present
Hanging air curtain sets windbreak mode, reduces vortex to change wind direction, makes to gather gas and enters main airstream to prevent watt
This transfinites, and is not easy to adjust due to hanging air curtain or setting windbreak fixed single, when main airstream wind speed or air quantity change, prevents
What only gas compacting effect was just shown is not sufficiently stable, and the presence of screen, increases the ventilation resistance of working face, makes working face
Air quantity reduces；Windbreak moves forward with the advance of the face, and every shifting frame is primary, need to tear open, to build windbreak primary, causes worker's labour strong
Degree is big, the construction time is long.
Utility model content
The purpose of the utility model is to provide it is a kind of it is easy to use, effect is preferable, needed according to scene adjustable comprehensive
The distinguished and admirable regulation device of mining face upper corner.
To achieve the goals above, the utility model includes: fixed disk, fixed pin, U-shaped rotation axis, hanging bar, adjusts silk
Thick stick, air regulating board, the side wall of fixed disk are provided with fixed pin, and the lower end of fixed disk is fixedly connected with hanging bar, in hanging bar
Portion is installed with U-shaped rotation axis, and the both ends of U-shaped rotation axis are fixedly connected with air regulating board, is installed with adjusting screw in the lower part of hanging bar, adjusts
Withstand air regulating board in the end of section lead screw.
The position of the corresponding hanging bar in the air regulating board upper end is provided with concave port.
When in use, the utility model is fixed below fully-mechanized mining working upper corner hydraulic support top beam on pinhole,
By rotation hanging bar, using adjusting screw adjust air regulating board, can up and down, left and right adjustment air regulating board angle, make wind deflector
It forms an angle with break line, the fresh distinguished and admirable forcibly changing direction in part is blowed into upper corner using wind deflector, to reach drop
The purpose of low gas at upper corner concentration can be convenient adjustment for different section, different air quantity wind speed, different time, play
Regulation upper corner is distinguished and admirable, reduces the effect of gas at upper corner.With easy to use, effect is preferable, being needed according to scene can be with
When the features such as adjusting.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the right view of the structural schematic diagram of the utility model.
Specific embodiment
As seen from Figure 1, Figure 2, the utility model includes: fixed disk 1, fixed pin 2, U-shaped rotation axis 3, hanging bar 4, adjusts
Lead screw 5, air regulating board 6.The side wall of fixed disk 1 is provided with fixed pin 2, and fixed disk is fixed on fully-mechanized mining working using fixed pin
Below upper corner hydraulic support top beam on pinhole.The lower end of fixed disk is fixedly connected with hanging bar 4, and hanging bar is adopted for cylinder
It is screwed in fixed disk with silking connection type, is conveniently adjusted.U-shaped rotation axis 3, U-shaped rotation are installed at the middle part of hanging bar 4
The both ends of axis are fixedly connected with air regulating board 6, and U-shaped rotation axis can be rotated around hanging bar.Adjusting is installed in the lower part of hanging bar 4
Air regulating board 6 is withstood in lead screw 5, the end of adjusting screw 5, twists the rotation adjustable air regulating board tilt angle of adjusting screw.For the ease of
Air regulating board angle is adjusted, the position of corresponding hanging bar is provided with concave port 7 in 6 upper end of air regulating board, is not hung when adjusting air regulating board
Bar influences.Air regulating board is fabricated to cuboid arcuate structure, is conducive to distinguished and admirable steady shunting.Fixed disk 1, fixed pin 2, U-shaped rotation
Axis 3, hanging bar 4, adjusting screw 5, air regulating board 6 are all made of mining metal material and are made, whole to adapt to underground coal mine environmental requirement
Body mopping and hydraulic support color-match, are convenient for managing.
