Abstract
The utility model relates to a cable turning and dragging device for a coal mining machine used in comprehensive mining; wherein, the whole device is arranged in a cable groove; a trailer is provided with a fixed pulley; the back end of the trailer is provided with back plates; a cable dragging wheel is arranged between the two back plates; one end of the cable is connected with a cable drawbar for the coal mining machine and the other end bypasses the cable dragging wheel and is connected with a power outside a well; a steel plate of one end part of the cable groove is provided with connection points and the fixed pulley; steel wires are attached to the connection points; the steel wires first bypasses the fixed pulley in the trailer, then bypasses the fixed pulley on the steel plate and finally bypasses the fixed pulley outside the cable groove and are connected with the cable drawbar for the coal mining machine. Using the cable turning dragging device for the coal mining machine can avoid fracture of the cable caused by repeated bending, prolong the service life of the cable, meanwhile, prevent the cable from dropping out from the cable groove so that production safety is ensured, mining efficiency is improved; due to a coal scratch board at the front end of the trailer, float coal and gangue in the cable groove can be cleared up, therefore manpower is saved.
Description
1, technical field:
The electric cable for coal mining machine break-in actuator that the utility model uses when relating to a kind of coal mine fully-mechanized mining.
2, background technology:
Colliery is combined when adopting operation, end cable is to be positioned in the cable trough behind the coal-winning machine, because the cable trough height is only than about the big twice of cable thickness, drag in the process that cable moves back and forth at coal-winning machine, cable is back and forth stacked, be easy loss cable life,, fall on the scratch board conveyor and drawn bad again easily by dropping out in the cable trough.Usually need to be equipped with the professional cable is nursed, once cable is run out of cable trough, just need to shut down cable is resetted, so promptly delay production, nurse cable personnel's work danger is also big.
3, summary of the invention:
The purpose of this utility model is to propose a kind of cable that drags, and regulates the electric cable for coal mining machine break-in actuator of cable at the cable trough inner height.
The purpose of this utility model is achieved in that electric cable for coal mining machine break-in actuator, integral body is placed in the cable trough, it is by trailer and the fixed pulley that is installed in the trailer, and the cable that is installed in the trailer rear portion drags wheel, and the fixed pulley of installing in the cable trough end is main the composition.In the trailer is cavity, is equiped with the fixed pulley that can horizontally rotate in it.Be provided with a pair of vertical back plate in the trailer rear end, between two back plates, be equiped with the cable that can vertically rotate and drag wheel, cable drags the distance of wheel lower end between cable trough and is not less than cable thickness, cable one end is connected with the electric cable for coal mining machine draw bar, the other end walk around cable drag the wheel be connected with the well external power, the steel plate of cable trough one end is provided with a tie point and a fixed pulley, be that steel wire is arranged on the tie point, this steel wire is walked around the fixed pulley in the trailer earlier, walk around the fixed pulley on the steel plate subsequently, the fixed pulley of walking around the outer other end of cable trough at last again is connected with the electric cable for coal mining machine draw bar.
Drive trailer by coal-winning machine, trailer spurs cable back and forth, has reached the purpose that drags cable automatically, uses this electric cable for coal mining machine break-in actuator, can avoid cable warpage and rupturing repeatedly, prolonged cable useful life, avoided cable simultaneously, guaranteed production safety by dropping out in the cable trough, improved coal mining efficient, by the coal scraper plate of trailer front end, also can clear up the float coal in the cable trough, spoil, save manpower.
4, description of drawings:
Concrete structure of the present utility model is provided by following drawings and Examples:
Fig. 1 is an electric cable for coal mining machine break-in actuator structural representation.
Legend: 1, electric cable for coal mining machine draw bar, 2, steel wire, 3, the cable roller, 4, tray, 5, trailer, 6, fixed pulley, 7, fixed pulley, 8, coal scraper plate, 9, sidewinder post, 10, roller, 11, the back plate, 12, cable drags wheel, 13, cable, 14, fixed pulley.
5, embodiment:
Embodiment: as shown in Figure 1, electric cable for coal mining machine break-in actuator integral body is placed in the cable trough, it is by trailer 5 and the fixed pulley 6 that is installed in the trailer 5, and the cable that is installed in trailer 5 rear portions drags wheel 12, and the fixed pulley of installing in the cable trough end 7,14 is main composition.Trailer is equiped with four groups of rollers 10 for 5 times, each two groups of front and back, and being separated by between every group of roller 10 is not less than 10cm, and trailer 5 front ends are provided with coal scraper plate 8, and 8 ends of coal scraper plate, contact at the cable trough bottom.Trailer 5 upper ends are provided with tray 4, and there is steel wire 2 in system on it, and this steel wire 2 is connected with electric cable for coal mining machine draw bar 1, are cavity in the trailer 5, are equiped with the fixed pulley 6 that can horizontally rotate in it.Be provided with a pair of vertical back plate 11 in trailer 5 rear ends, back plate 11 upper ends are provided with cable roller 3, between two back plates 11, be equiped with the cable that can vertically rotate and drag wheel 12, cable drags the distance of wheel 12 lower ends between cable trough and is not less than cable 13 thickness, cable 13 1 ends are connected with electric cable for coal mining machine draw bar 1, the other end is walked around cable and is dragged wheel 12 and be connected with the well external power, and cable 13 both sides are against on the cable roller 3.On the outer wall of trailer 5 two sides, also be equiped be no less than four vertically sidewinder post 9, sidewinder post 9 and on the cable trough sidewall, roll, trailer 5 is advanced by the cable trough shape, prevent trailer 5 scratch cable cell walls.The steel plate of cable trough one end is provided with a tie point and a fixed pulley 7, be that steel wire 2 is arranged on the tie point, this steel wire 2 is walked around the fixed pulley 6 in the trailer 5 earlier, walks around the fixed pulley 7 on the steel plate subsequently, and the fixed pulley 14 of walking around the outer other end of cable trough at last again is connected with electric cable for coal mining machine draw bar 1.
When coal-winning machine was positioned at high order end, trailer 5 was positioned at the middle part of whole cable trough, along with coal-winning machine moves right, and pulling steel wire 2, cable 13 is lax simultaneously.Steel wire 2, drives trailer 5 and moves right again by the fixed pulley 6 on the trailer 5 by the break-in of two fixed pulleys 7,14, cable 13 tensions that trailer 5 will relax and.Fixed pulley 6 in the trailer 5 and the relative movable pulley of trailer 5 common compositions, move from left to right time a time at coal-winning machine like this, trailer 5 half the length of cable trough of in cable trough, only need advancing, thus with cable 13 firm dragging in cable trough, the phenomenon that cable 13 drops out can not take place.
