Abstract
The invention discloses a coal blocking device which saves materials and is easy to mount and maintain. The coal blocking device comprises a fixed plate and a coal blocking sheet which is fixed on the fixed plate, wherein the fixed plate consists of a front clamping plate and a back clamping plate; the coal blocking sheet is positioned between the front clamping plate and the back clamping plate; at least two adjusting frames are welded on the back surface of the front clamping plate, and round holes are formed in the adjusting frames; screw rods are welded on the back of the back clamping plate and penetrate out of the round holes which are formed in the adjusting frames; and adjusting screw caps are positioned on the screw rods which are between the adjusting frames and the back clamping plate, and are matched with threads of the screw rods. According to the coal blocking device, the front clamping plate is matched with the back clamping plate, and the clamping force of the front clamping plate and the back clamping plate can be adjusted by adjusting the screw caps, so that the position of the coal blocking sheet between the front clamping plate and the back clamping plate is easy to adjust or the coal blocking sheet between the front clamping plate and the back clamping plate is easy to replace.
Description
Technical field
The present invention relates to a kind of coal mine machinery, especially for the matching used retaining device for coal of travelling apron.
Background technology
Spillplate is that travelling apron is in operation process; Indispensable parts; It can make travelling apron in the process of carry coal; Make coal on adhesive tape, be piled into stocking angle preferably, thereby avoid rubber belt from deviating and transportation to shed coal along the line, improve travelling apron functional reliability and fortune coal efficient.The spillplate that uses now is made up of steel adapter plate, retaining coal skin, and adapter plate and adhesive tape can not direct contacts, not so can the scratch adhesive tape.Therefore, institute's block selecting coal skin is generally the rubber composition.In use, retaining coal skin is is very easily worn and torn, after wearing and tearing go beyond the limit, just need in time to change because retaining coal skin keeps being in Frotteurism with the adhesive tape of operation always.And adapter plate and retaining coal skin adopt disposable processing in manufacturing process, and promptly adapter plate is spirally connected with retaining coal skin and is one.Because this fixed form, make the mounting hole on the adapter plate corresponding with mounting hole on the retaining coal skin, just can not adjust again after accomplishing fluently mounting hole.Transfinite when needing to change when retaining coal shelling decreases, because the position of mounting hole on the adapter plate is located, when more shifting gears the coal skin, mounting hole processing is difficult for one-time-reach-place, is not that setting angle is not enough, is exactly highly unreasonable, and is difficult to regulate, and influence is produced.Simultaneously, retaining coal shelling must be changed after decreasing and transfiniting, and causes waste of material, and frequent more gearshift coal skin has also reduced work efficiency.
Summary of the invention
The purpose of this invention is to provide a kind of not only saving in material but also be easy to the retaining device for coal of installation and maintenance.
Technical scheme of the present invention is: comprise adapter plate and be fixed on the retaining coal skin on the adapter plate; Said adapter plate is made up of front plate and rear plate; Retaining coal skin is between front plate and rear plate, and the front plate back side is welded with at least two adjusting brackets, and adjusting bracket is provided with circular hole; The rear plate back is welded with screw rod, and this screw rod passes the set circular hole from adjusting bracket, regulates nut on the screw rod between adjusting bracket and the rear plate, and cooperates with screw flight.
Because the structure that adopts front plate and rear plate to cooperate among the present invention just can be regulated the gripping power of front plate and rear plate through regulating nut, makes the retaining coal skin that is clipped between front plate and the rear plate be easy to adjusting position.Therefore, after retaining coal shelling damage transfinites, front plate and rear plate can be unclamped, the subcutaneous accent of coal will be kept off, and then the fastening adjustment nut.Not only save retaining coal leather material, also made the operating process of the coal skin of more shifting gears more quick, improved work efficiency.
Description of drawings
Fig. 1 is the schematic perspective view of structure of the present invention.
Fig. 2 is the STRUCTURE DECOMPOSITION scheme drawing of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further explain, but do not constitute any restriction of the present invention.Illustrated in figures 1 and 2; The present invention includes adapter plate and be fixed on the retaining coal skin 1 on the adapter plate, said adapter plate is made up of front plate 3 and rear plate 2, and retaining coal skin 1 is between front plate 3 and rear plate 2; Front plate 3 back sides are welded with at least two adjusting brackets 4, and adjusting bracket 4 is provided with circular hole.Rear plate 2 backs are welded with screw rod 5, and this screw rod 5 passes the set circular hole from adjusting bracket 4, regulate nut on the screw rod 5 between adjusting bracket 4 and the rear plate 2, and with screw rod 5 screws thread fit.During use, adjusting bracket 4 is fixed on the pedestal 6, behind retaining coal skin 1 wear and tear overrun, needs adjustment retaining coal skin 1; Nut is regulated in turn this moment, and the adjusting nut is moved to rear plate 2 directions, promptly regulates nut and leaves mutually with adjusting bracket 4, forms a fixed gap; To the slot milling that contracts behind the rear plate 2, front plate 3 is left with rear plate 2 mutually, the Clamping force that retaining coal skin 1 receives reduces, and will keep off coal skin 1 then and be lowered to correct position; Nut is regulated in reverse more at last turn, regulates the restriction of nut conditioned frame 4, after arriving certain position, can only on screw rod 5, rotate and can not move; Therefore, force screw rod 5 to drive rear plate 2 at last and move ahead, make front plate 3 and rear plate 2 clamp retaining coal skin 1.
Claims (1)
