Description
Technical field:
The utility model relates to the blast equilibrium and the opening device of a kind of coal mine lower wind door both sides, in the time of realizing that especially the air door pressure at both sides is big, and artificial open function.
Background technology
At present, along with the progressively expansion of Coal Production ability, the stope scope is increasing, and the ventilation route is more and more longer, and mine resistance is increasing, has been equipped with more powerful ventilating fan for overcoming the resistance mine, and bigger negative pressure is provided; In addition, the down-hole mechanical degree is more and more higher, and equipment is more and more, increasing, and mine blast volume is regulated and the needs of main equipment transportation in order to satisfy, and must install the air door of large-size.Under the normal condition, the air door size is about 4.5 square metres, and the leeway of air door both sides, the main air entering and returning of mine lane is all greater than 1000 Pascals, that is to say that blast acts on pressure on the air door generally all greater than 4500 newton, and general personnel can't open.At present, the way that solves is to change to use the balance air door of splitting or adopt mechanically operated way to solve, and the balance air door inleakage of splitting is big, complex structure easily breaks down, and also very complex fault is also a lot of for mechanical driving structure, the cost height affects greatly to the colliery safety in production.
The utility model content:
The purpose of this utility model is, overcome existing air door structure complexity, fault many, leak out many, cost is high, can not be smoothly, the drawback of rapid, light unlatching, provide a kind of and can successfully realize the function that the air door both sides are all pressed rapidly, opened, and colliery air door with low cost, simple to operate all presses off opening device.。
The utility model is achieved in that
A kind of colliery air door all presses off opening device, and it comprises air door, slip plugging device; Air door is provided with balancing orifice; The slip plugging device is installed on the balancing orifice of air door by bolt.
Described slip plugging device comprises shell body, is positioned at stiff spring, the shutoff slide block of shell body, the handle that slides, slip handle sliding tray; Stiff spring, shutoff slide block, the handle that slides link to each other successively; Stiff spring one side is fixed on the shell body inboard, and opposite side is connected with the shutoff slide block; The handle that slides is positioned at the handle loose slot that slides.
In the slip plugging device, also be connected with pull rope between shutoff slide block and the slip handle; Be respectively equipped with left baffle on the shutoff slide block both sides sliding position of enclosure interior outside.
In slip plugging device shell body inside, at the shutoff slide block with slide and also to be provided with directive wheel between the handle, connect the shutoff slide block and the pull rope of the handle that slides is wrapped on the directive wheel.
Described air door is provided with the handle loose slot that slides, and corresponding with the slip handle sliding tray in the slip plugging device.
The know-why that the utility model solves its technical problem is: singly blow in front of the door in installation, at balancing orifice that suitable dimension is set near the open side correct position and handle loose slot, the colliery air door of making in advance all presses off the opening device along continuous straight runs and is fixed on the air door.Slide block abuts against on the right baffle-plate under the acting in conjunction of spring tension and blast, and balancing orifice is covered fully, and whole air door does not leak out.The pulling handle, handle drives wire rope and slides in the handle loose slot, the rope traction slide block slides to the right in device box, balancing orifice progressively opens wide, when slide block slides into right baffle plate, balancing orifice is unlimited fully, and the blast of air door both sides reaches balance rapidly, and the power that blast acts on the air door reduces rapidly.Continue the pulling handle, handle, draws back air door on air door very like a cork by directive wheel, wire rope, slide block and right baffle effect.By during the air door, unclamp handle the people, under the effect of device inner spring pulling force, slide block and handle set back by the traction of spring and wire rope, the balancing orifice complete closed, and air door is closed, operate as normal.Thereby reach the purpose that air door is quick, easily all press, open.
The utility model has the advantages that simple in structurely, with low cost, safe, can manually open the air door in the big zone of leeway under the coal mine rapidly, like a cork.
Below in conjunction with accompanying drawing the utility model is described further.
