Description
Technical field
The present invention relates to travelling apron change slope guide piece in a kind of coal mine roadway.
Background technology
The mining construction of complicated geological, during tunneling construction, majority is constructed along coal seam, so, the tunnel of construction is inevitable through less recessed section of radius of curvature, when travelling apron is used in tunnel through the less recessed section of carry coal of radius of curvature, if directly by this section, adhesive tape is very easily unsettled when moving, cause and spread coal, and the bastard coal tumbling is also easily hurted sb.'s feelings.In addition, when travelling apron starts, at less recessed section of radius of curvature, adhesive tape is easy and back scraping also, produce belt tearing, cause the accident, and if at so recessed section, locate to set up again a travelling apron, corresponding belt feeder driver and dynamo-electric establishing all will increase, and the power consumption of plant maintenance personnel's work capacity, increase equipment is also wanted corresponding increase.
Summary of the invention
The object of this invention is to provide a kind of personnel of being conducive to, equipment normally keeps the safety in production during through less recessed section of radius of curvature at travelling apron, the serviceability rate of raising equipment, reduce service expenditure, reduce the interior travelling apron of coal mine roadway of equipment investment and personnel's input with becoming slope guide piece.
In coal mine roadway of the present invention, travelling apron is with becoming slope guide piece, comprise frame, in frame, along fore-and-aft direction, be provided with transportation rubber belt, stand after left and right two ends of described frame are vertically respectively equipped with one, bend pulley seat after the top of stand trailing flank is fixed with respectively one after two, bend pulley after being provided with one along left and right horizontal direction between bend pulley seat after two, two ends of the rotating shaft of rear bend pulley are arranged on corresponding rear bend pulley seat, the bottom of two described rear stand trailing flanks is provided with rear girdle roller along left and right horizontal direction, two ends of rear girdle roller are arranged on respectively in corresponding rear stand,
Left and right two ends that are positioned at described rear stand front side in described frame are vertically respectively equipped with a front stand, the top of two front stand leading flanks is fixed with respectively a front bend pulley seat, two front bend pulley seats are positioned at the below of two described rear bend pulley seats, between two front bend pulley seats, along left and right horizontal direction, be provided with a front bend pulley, two ends of the rotating shaft of front bend pulley are arranged on corresponding front bend pulley seat, the diff-H of the bottom of the top of front bend pulley periphery and described rear bend pulley periphery is less than 200mm, described transportation rubber belt extends from front to back, from top to bottom around the latter half periphery of rear bend pulley, then transportation rubber belt extends from back to front, from top to bottom around the first half periphery of front bend pulley, then transportation rubber belt extends from front to back successively through the neutral gear between stand after two front stands and two below front bend pulley, then the top that the lower surface of transportation rubber belt is pasting described rear girdle roller is by rear girdle roller, transportation rubber belt is got back to the front end of travelling apron from the below of rear girdle roller.
In coal mine roadway of the present invention, travelling apron is with becoming slope guide piece, wherein two described rear bend pulley seat upper-lower positions are arranged in described rear stand adjustablely, two described front bend pulley seat upper-lower positions are arranged on described front stand adjustablely, the top of two described front stands adopts front cross rail to be connected, and the top of two described rear stands adopts after cross member to be connected.
In coal mine roadway of the present invention, travelling apron is with becoming slope guide piece, wherein said rear girdle roller upper-lower position is arranged on described rear stand adjustablely, the place ahead that is positioned at described front stand in described frame is provided with front belt supporting roller, two ends of front belt supporting roller are arranged on respectively in frame, and the lower surface of getting back to the described transportation rubber belt section of travelling apron front end is pasting the top of described front belt supporting roller by front belt supporting roller.
In coal mine roadway of the present invention, travelling apron is with becoming slope guide piece, and wherein two described front stands and two described rear stands adopt respectively channel-section steel to make.
In coal mine roadway of the present invention, travelling apron is with becoming slope guide piece in use, and it can produce following beneficial effect:
1, solution is broken with coal and is fallen cash problem.When the top of transportation rubber belt adhesive tape is during through less " recessed " grade change point of radius of curvature, it is unsettled that this section of adhesive tape can produce, and now the one-tenth groove angle of adhesive tape changes, because adhesive tape has left trough idler group, general groove angle decreases, makes partial material spread out.If recessed section of radius of curvature is larger, can set up on the way pinch roller and avoid upspringing of adhesive tape, but recessed section that radius of curvature is less just produces little effect, spreading coal, to fall cash just unavoidable, and the bulk spoil dropping also causes security threat to the workman in advancing, have no small potential safety hazard, travelling apron spreads coal when slope guide piece can avoid transportation rubber belt to pass through less " recessed " grade change point of radius of curvature and falls cash with becoming in coal mine roadway of the present invention.
2, prevent that transportation rubber belt from tearing.At the less concave point place of radius of curvature, transportation rubber belt can be easy to make operating adhesive tape and top board to swipe by unsettled, causes adhesive tape to tear, and occurs cut on transportation rubber belt, reduces the service life of adhesive tape, and serious belt phenomenon may occur.Travelling apron can prevent that with change slope guide piece transportation rubber belt from can, by unsettled, avoid transportation rubber belt to tear in coal mine roadway of the present invention.
3, need not set up travelling apron.In prior art, if run into the recessed section of grade change point that radius of curvature is less, if can not solve this place's problem by setting up pinch roller, the necessity of making use of momentum is set up a belt herein.Adopt travelling apron in coal mine roadway of the present invention with becoming slope guide piece, just need not set up travelling apron, reduce thus equipment investment.
In sum, travelling apron has and is conducive to personnel, equipment and normally keeps the safety in production when travelling apron passes through less recessed section of radius of curvature with becoming slope guide piece in coal mine roadway of the present invention, the serviceability rate of raising equipment, reduce service expenditure, reduce the feature that equipment investment and personnel drop into.
Below in conjunction with accompanying drawing, travelling apron in coal mine roadway of the present invention is described in further detail with becoming slope guide piece.
