[0023] When the steel rope becomes loose after long-term use and the fixed steel rail and the second moving belt bracket are inconvenient to move, the pen-shaped cylinder contracts and drives the supporting bottom block to slide toward the side of the limit bending plate. After sliding to the bottom, the hydraulic telescopic rod extends and opens to drive the L-shaped support and the hook pulling wheel to move the steel rope toward the tensioning pulley rod side. When the hook pulling wheel extends and moves beyond the steel rope, it stops extending, and the pen-shaped cylinder extends and drives the supporting bottom block to slide toward the side of the detachable L-shaped tensioning adjustment plate, so that the hook pulling wheel is hung and hooked on the steel rope. At this time, the hydraulic telescopic rod contracts and drives the L-shaped support and the hook pulling wheel to move backward, so that under the action of the triangular distribution of the hook pulling wheel and the two auxiliary support wheels, the steel rope is tightened to achieve the tension adjustment of the steel rope, so as to meet the use of different occasions. At the same time, it can provide tension adjustment guarantee when the fixed steel rail and the second moving belt bracket are inconvenient to move, thereby completely replacing the problem of manual movement of cable parts and improving work efficiency.

The gangue and slag drilled down by the anchor mining machine are transported to the rear end through the secondary transport belt, fall onto the outer transport belt member 5, and then transported out.

[0036] In this embodiment, two U-shaped connecting plates 13 are symmetrically welded on the inner wall of the tensioning pulley rod 12. The two U-shaped connecting plates 13 are respectively clamped on the outer frame of the secondary belt bracket 2 and fastened together by bolts, so that the tensioning pulley rod 12 can be stably installed.

[0037] In this embodiment, the top surface of one end of the fixed rail 1 facing away from the second conveyor belt support 2 is connected to a cable rack 11 by bolts. The cable rack 11 is used to reel in excess cables. A fixed bracket 6 is installed on one side of the cable rack 11 and located on the top surface of the fixed rail 1 by bolts.

The cable member 9 supplies power to the anchor digging machine in front from the rear.

[0038] In this embodiment, a detachable L-shaped tensioning adjustment plate 16 is installed on the outer wall of the tensioning pulley rod 12. The detachable L-shaped tensioning adjustment plate 16 has two branch connecting rods 17 at one end close to the tensioning pulley rod 12. The free ends of the two branch connecting rods 17 are fixedly connected to the tensioning pulley rod 12 by a first locking bolt 21.

An auxiliary support wheel 22 is rotatably installed on the inner wall of each branch connecting rod 17. The two auxiliary support wheels 22 abut against the steel plate on one side of the tensioning pulley rod 12. The rope 20 and the two auxiliary support wheels 22 are connected by a movable telescopic component with a hook pulling wheel 23 that can be hung on the steel rope 20 and pulled backward to tension and adjust the steel rope 20. When the hook pulling wheel 23 pulls the steel rope 20 backward, the hook pulling wheel 23 and the two auxiliary support wheels 22 are distributed in a triangular shape, so that the tension of the steel rope 20 can be adjusted when the steel rope 20 becomes loose after long-term use and the fixed rail 1 and the two movable belt brackets 2 are inconvenient to move, so as to meet the use of different occasions. At the same time, it can provide a guarantee for tension adjustment when the fixed rail 1 and the two movable belt brackets 2 are inconvenient to move, thereby completely replacing the problem of manual movement of the cable member 9 and improving work efficiency.

[0039] In this embodiment, a limiting bending plate 24 is integrally formed at the tail end of the detachable L-shaped tensioning adjustment plate 16, and a supporting bottom block 26 is slidably connected between the limiting bending plate 24 and the detachable L-shaped tensioning adjustment plate 16. The supporting bottom block 26 is penetrated by two symmetrical positioning rods 27 and is respectively fixedly connected to the limiting bending plate 24 and the inner wall of the detachable L-shaped tensioning adjustment plate 16. The movable telescopic component includes a pen-shaped cylinder 25 fixedly installed in the middle position of the inner wall of the limiting bending plate 24 and a hydraulic telescopic rod 28 installed on the outer wall of the supporting bottom block 26. The hook pulling wheel 23 is rotatably installed on the L-shaped support 29, and the telescopic free end of the hydraulic telescopic rod 28 is fixedly connected to the L-shaped support 29.

[0040] In this embodiment, when it is necessary to use the hook pulling wheel 23 to adjust the tension of the steel rope 20, a detachable L-shaped tensioning adjustment plate 16 is installed, so that the two auxiliary support wheels 22 are against the steel rope 20 toward the tensioning pulley rod 12 side, and the pen-shaped cylinder 25 contracts to drive the supporting bottom block 26 to slide toward the side of the limit bending plate 24. After sliding to the bottom, the hydraulic telescopic rod 28 extends and opens to drive the L-shaped support 29 and the hook pulling wheel 23 to move toward the steel rope 20 on the tensioning pulley rod 12 side. When the hook When the pulling wheel 23 extends and moves beyond the steel rope 20, it stops extending, and the pen-shaped cylinder 25 extends to drive the supporting bottom block 26 to slide toward the side of the detachable L-shaped tensioning adjustment plate 16, so that the hook pulling wheel 23 is hung and hooked on the steel rope 20. At this time, the hydraulic telescopic rod 28 contracts to drive the L-shaped support 29 and the hook pulling wheel 23 to move backward, so that under the action of the triangular distribution of the hook pulling wheel 23 and the two auxiliary support wheels 22, the steel rope 20 is tightened to achieve the tension adjustment of the steel rope 20.

[0041] In this embodiment, an L-shaped lower pressure plate 18 in an inverted horizontal position is fixed to the top of the tensioning pulley rod 12, and a supporting rib 10 is welded to the vertical inner wall of the L-shaped lower pressure plate 18, thereby providing a stable supporting force for the L-shaped lower pressure plate 18 to prevent the L-shaped lower pressure plate 18 from breaking due to stress. An electric lifting rod 31 is installed on the inner wall of the L-shaped lower pressure plate 18 by bolts, and the lower pressure auxiliary wheel 19 is rotatably installed in an inverted U-shaped support plate 33, and the bottom lifting end of the electric lifting rod 31 is fixedly connected to the U-shaped support plate 33 by bolts.

[0042] In this embodiment, when the secondary conveyor belt support 2 moves forward on the fixed rail 1 (such as Figure 1 The left side of the figure is the forward direction) when the cable 9 moves too much, the auxiliary tensioning wheel 15 at the top of the tensioning pulley rod 12 is far away from one of the adjacent hook rings 8. At this time, the cable member 9 is bound to fall in an arc trajectory in this interval. Therefore, it is necessary to pull an adjacent hook ring 8 toward the auxiliary tensioning wheel 15 at the top of the tensioning pulley rod 12. At this time, it is necessary to relax the steel rope 20 so that the steel rope 20 between the top of the tensioning pulley rod 12 and the fixed bracket 6 is in a relaxed state. The electric lifting and lowering rod 31 extends downward to drive the pressing auxiliary wheel 19 to descend, and the pressing auxiliary wheel 19 presses the steel rope 20 down, so that the tensioning pulley rod 12 is close to the auxiliary tensioning wheel 15. The steel rope 20 on one side of the auxiliary tensioning wheel 15 at the top of 12 is in an inclined downward state, and at this time, the hook ring 8 will slide on the steel rope 20 toward the side of the auxiliary tensioning wheel 15 at the top of the tensioning pulley rod 12 due to its own weight, thereby shortening the distance between the auxiliary tensioning wheel 15 at the top of the tensioning pulley rod 12 and one of the adjacent hook rings 8, thereby solving the problem that the cable component 9 will fall in an arc trajectory in this interval, thereby preventing the cable component 9 from being entangled or hooked by the components of the lower second transport belt bracket 2 and preventing it from being hit by gangue and slag falling from the rear end of the second transport belt bracket 2, thereby increasing the service life of the cable component 9.

[0043] In this embodiment, the downward pressing auxiliary wheel 19 can press down the steel rope 20 near the top end of the tensioning pulley rod 12 when the steel rope 20 is loose, so that the hook ring 8 slides down and approaches. An inclined extension rod 32 is arranged on one side of the downward pressing auxiliary wheel 19. An adjustable limiting rail 35 for limiting the downward movement of the hook ring 8 is installed on the inner wall of the inclined extension rod 32. The position of the adjustable limiting rail 35 is adjusted according to the required spacing, and the position of the adjustable limiting rail 35 is installed by the second locking bolt 30. A plurality of threaded holes 34 for connecting the second locking bolt 30 are equidistantly provided on the outer wall of the inclined extension rod 32.

[0044] In this embodiment, when the hook ring 8 slides down, the hook ring 8 can be blocked by the adjustable limiting railing 35 according to the selected spacing size, thereby meeting the required distance adjustment and improving the use efficiency.

[0045] In this embodiment, the anchor mining machine is provided with a PLC for controlling the opening and closing of various components. The PLC model can be selected according to actual needs. In the utility model, the PLC model is S7-200, which has the advantages of high reliability, strong anti-interference ability and convenient maintenance.

[0046] How it works

[0047] The cable self-moving sliding device of the anchor mining machine can straighten the steel rope 20 when the fixed steel rail 1 is stationary and the second moving belt bracket 2 moves forward and backward, and can also straighten the steel rope when the fixed steel rail 1 moves forward but the second moving belt bracket 2 is stationary;

[0048] When it is necessary to use the hook pulling wheel 23 to adjust the tension of the steel rope 20, the detachable L-shaped tensioning adjustment plate 16 is installed, so that the two auxiliary support wheels 22 abut against the steel rope 20 toward the side of the tensioning pulley rod 12, and the pen-shaped cylinder 25 contracts to drive the supporting bottom block 26 to slide toward the side of the limit bending plate 24. After sliding to the bottom, the hydraulic telescopic rod 28 extends and opens to drive the L-shaped support 29 and the hook pulling wheel 23 to move toward the steel rope 20 on the side of the tensioning pulley rod 12. When the hook pulling wheel 23 extends and moves beyond the steel rope 20, it stops extending, and the pen-shaped cylinder 25 extends to drive the supporting bottom block 26 to slide toward the side of the detachable L-shaped tensioning adjustment plate 16, so that the hook pulling wheel 23 is hung and hooked on the steel rope 20. At this time, the hydraulic telescopic rod 28 contracts to drive the L-shaped support 29 and the hook pulling wheel 23 to move backward, so that the steel rope 20 is tightened under the action of the hook pulling wheel 23 and the two auxiliary support wheels 22 distributed in a triangular shape;

[0049] The steel rope 20 between the top of the tensioning pulley rod 12 and the fixed bracket 6 is in a relaxed state, and the electric lifting rod 31 extends downward to drive the downward pressure auxiliary wheel 19 to descend, and the downward pressure auxiliary wheel 19 presses down the steel rope 20, so that the steel rope 20 on the side of the auxiliary tensioning wheel 15 near the top of the tensioning pulley rod 12 is in an inclined downward state. At this time, the hook ring 8 will slide on the steel rope 20 toward the side of the auxiliary tensioning wheel 15 at the top of the tensioning pulley rod 12 due to its own weight, thereby shortening the distance between the auxiliary tensioning wheel 15 at the top of the tensioning pulley rod 12 and one of the adjacent hook rings 8, thereby solving the problem that the cable component 9 will fall in an arc trajectory in this interval.
