Background technology
Coal-winning machine need move up and down along coal-face in the coal mining process, be connected with a cable on the coal-winning machine as driving source is provided, coal-winning machine needs the water pipe of a soft material formation to provide cooling water that coal-winning machine is cooled off and dedusting in the coal mining process simultaneously.The cable and the water pipe of coal-winning machine generally all bundle, be referred to as the pipe cable, the pipe cable is that soft material constitutes, the pipe cable is arranged in the cable channel of scratch board conveyor, coal-winning machine is arranged on the scratch board conveyor, on coal-winning machine, be provided with the pipe cable access portion that is used for the access tube cable, pull out and be linked into the pipe cable access portion on the coal-winning machine the cable channel of pipe cable from scratch board conveyor, and along with coal-winning machine moves up and down.
Coal-winning machine pipe cable is to be dragged to outlet under the work plane from the work plane upper outlet along work plane, and then be connected in the pipe cable access portion of coal-winning machine, after coal-winning machine runs to the work plane upper outlet, down walking again, it is motionless to exist the holding phenomenon to cause electric cable for coal mining machine to block in cable channel because of scratch board conveyor cable channel and coal-winning machine pipe cable, after need manually going like this pipe cable of coal-winning machine set upright, coal-winning machine pipe cable can move in cable channel smoothly, such situation can cause will having all the time a coal miner to remove keeping the pipe cable, owing to rib danger such as wall caving can appear at any time, so exist very big security threat the workman of and then coal-winning machine pipe cable walking in the coal mining process.In addition, as shown in Figure 5, coal-winning machine is when running to work plane upper outlet position, and the pipe cable 8 of pipe cable access portion 1 that is connected coal-winning machine forms two-layer pipe cable because of being that nature is shelved in the dealing campaign; As shown in Figure 6, coal-winning machine is Way out when walking down again, the pipe cable access portion 1 of coal-winning machine is along with Way out motion under the coal mining cabinet, " S " type totally three layers of pipe cable 8 have then been formed on work plane top, can produce cable channel that pipe cable be extruded scratch board conveyor at thin seam working surface this moment, occur hanging up the security incident of leaking electricity and hurting sb.'s feelings behind the pipe cable, also be unfavorable for reducing the height of mining.
The utility model content
The technical problem that the utility model solves is: a kind of coal-winning machine pipe cable tensioning apparatus is provided, when coal-winning machine at the upper outlet of work plane with down between the outlet during dealing campaign, manage cable and can be in tensioning state automatically all the time, can not form three plies.
The technical solution of the utility model is: a kind of coal-winning machine pipe cable tensioning apparatus, comprise the pipe cable access portion that is arranged on the coal-winning machine, its key is, comprise isolated first fixed pulley and second fixed pulley, be provided with first movable pulley and second movable pulley between described first fixed pulley and second fixed pulley, the axle of first movable pulley and the axle of second movable pulley are parallel to each other and are connected by a link; Pipe cable access portion on the coal-winning machine is positioned between second movable pulley and second fixed pulley; One steel cable has a fixed end and a shift end, and the shift end of described steel cable is walked around first movable pulley, first fixed pulley and second fixed pulley successively and is fixedly connected on pipe cable access portion on the coal-winning machine; One pipe cable is walked around second movable pulley and is linked into pipe cable access portion on the coal-winning machine.
Coal-winning machine is arranged on the scratch board conveyor, and scratch board conveyor is provided with cable channel, and described first movable pulley, second movable pulley and the pipe cable section that is positioned at second movable pulley below fall into described cable channel respectively.
The fixed end of steel cable and first fixed pulley all are positioned at the following outlet of coal-winning machine work plane, and second fixed pulley is positioned at the upper outlet of coal-winning machine work plane.
The shift end of described steel cable is fixedly connected on pipe cable access portion on the coal-winning machine by a spring.
The fixed end of described steel cable, first fixed pulley and second fixed pulley all are fixed on the base plate.
The fixed end of described steel cable, first fixed pulley and second fixed pulley all are fixed on the scratch board conveyor.
The beneficial effects of the utility model are: the utility model comprises isolated first fixed pulley and second fixed pulley, be provided with first movable pulley and second movable pulley between first fixed pulley and second fixed pulley, the axle of first movable pulley and the axle of second movable pulley are connected by link; Pipe cable access portion on the coal-winning machine is positioned between second movable pulley and second fixed pulley; One steel cable has a fixed end and a shift end, and the shift end of steel cable is walked around first movable pulley, first fixed pulley and second fixed pulley successively and is fixedly connected on pipe cable access portion on the coal-winning machine; One pipe cable is walked around second movable pulley and is linked into pipe cable access portion on the coal-winning machine.When coal-winning machine when the second fixed pulley direction is moved, coal-winning machine pulling pipe cable moves, manage cable and be in tensioning state this moment.When coal-winning machine when the first fixed pulley direction is moved, the shift end of steel cable is along with the motion of the pipe cable access portion on the coal-winning machine also groove first fixed pulley direction, because the other end of steel cable is fixed, first movable pulley is spurred by steel cable and moves towards the first fixed pulley direction, with first movable pulley be connected by link owing to second movable pulley this moment, therefore second movable pulley also follows the direction of first movable pulley towards east to move, in the case, though coal-winning machine is moving towards the first fixed pulley direction, but second movable pulley is also moving towards the first fixed pulley direction simultaneously, and therefore managing cable is in tensioning state all the time automatically.Therefore when coal-winning machine moved up and down at the upper outlet of work plane with between exporting down, soft pipe cable is the energy auto-tensioning all, can not form three plies, has reduced the nurse link to the pipe cable on the one hand, so has eliminated the potential safety hazard to the nurse personnel; Prevented that on the other hand the pipe cable is extruded cable channel and is hung up, thus the security incident of having avoided the electric leakage of pipe cable to hurt sb.'s feelings; And, therefore also improved the height of mining because the pipe cable can not form three plies.
