[0015] 1. The present invention discloses a large-scale mining belt winding device driven by a winch, comprising a base frame, a triangular support, a connecting shaft, a rotating rod, and a drive mechanism. The cut end of the old belt is fixedly wound onto the rotating rod. The drive motor is started, driving the worm gear to rotate, which in turn drives the worm and the second transmission rod to rotate. Through belt transmission, the third transmission rod rotates, which in turn drives the second gear to rotate, which in turn drives the first gear and the first transmission rod to rotate. This, in turn, drives the connecting shaft to rotate, which in turn drives the rotating rod to rotate, winding the cut old belt onto the rotating rod. Once the old belt is wound onto the rotating rod, the rotating rod is removed from between the two connecting shafts, and the rolled old belt is transported to a storage yard using a crane or forklift for neat stacking.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0028] like Figures 1 to 4As shown, a large mining conveyor belt winding device driven by a return-column winch includes a base frame 1; triangular brackets 2 are fixedly connected to both sides of the top surface of the base frame 1; a connecting shaft 3 is rotatably mounted on the top of the triangular brackets 2; a rotating rod 4 is installed between the two connecting shafts 3; and a driving mechanism 5 for driving the connecting shafts 3 to rotate is provided on the top of one side of the base frame 1.

[0029] Specifically, the base frame 1 is welded from multiple square tubes, the triangular bracket 2 is welded from the ends of three square tubes, and there is an included angle between two adjacent square tubes; the top of the triangular bracket 2 is fixedly connected to a sleeve, and the connecting shaft 3 is rotatably installed inside the sleeve.

[0030] The drive mechanism 5 includes a base fixed to the top surface of the base frame 1. A first transmission rod is fixedly connected to a connecting shaft 3 near the base, and the other end of the first transmission rod is rotatably connected to the side wall of the base. A first gear is fixedly connected to the outer ring of the middle part of the first transmission rod. A drive motor is fixedly connected to the top surface of the base, and a housing fixedly connected to the top surface of the base is provided between the drive motor and the first transmission rod. A worm gear is rotatably installed at the top of the inner cavity of the housing, and one end of the worm gear is fixedly connected to the output shaft of the drive motor. A second transmission rod is rotatably installed at the bottom of the inner cavity of the housing, and the second transmission rod is perpendicular to the worm gear. A worm gear is fixedly connected to the outer ring of the middle part of the second transmission rod. The worm gear meshes with the worm gear. A third transmission rod is rotatably installed below the first transmission rod. The third transmission rod is connected to the second transmission rod via a belt drive. A second gear is fixedly connected to the outer ring of the third transmission rod, and the second gear meshes with the first gear.

[0031] In practical use, the cut end of the old belt is fixed and wound onto the rotating rod 4. The drive motor is started, which drives the worm gear to rotate, which in turn drives the worm and the second transmission rod to rotate. Through belt transmission, the third transmission rod rotates, which in turn drives the second gear to rotate, which in turn drives the first gear and the first transmission rod to rotate. This, in turn, drives the connecting shaft 3 to rotate, which in turn drives the rotating rod 4 to rotate, winding the cut old belt onto the rotating rod 4. After the old belt is wound onto the rotating rod 4, the rotating rod 4 is removed from between the two connecting shafts 3, and the rolled old belt is transported to the storage yard by a crane or forklift for neat stacking. This not only facilitates the recycling of waste belts but also greatly reduces the space occupied in the storage area. Furthermore, the neat stacking is beneficial for later recycling.

[0032] In some embodiments, such as Figure 1 As shown, a crossbeam 6 is fixedly connected to the top surface of the base frame 1 at the end away from the triangular bracket 2; angle plates 7 are bolted to both ends of the top surface of the crossbeam 6; and a guide roller 8 is rotatably installed between the two angle plates 7.

[0033] Specifically, inclined plates are fixed to both sides of the crossbeam 6, and the bottom end of the inclined plates is fixed to the inner wall of the base frame 1; the corner plate 7 is fixed to the crossbeam 6 by multiple bolts; the inner roller of the guide roller 8 is fixed to the corner plate 7 by bolts, and the outer roller of the guide roller 8 can roll; there is a gap between the two guide rollers 8, and the gap can allow the old belt to pass through.

[0034] The cut end of the old belt is passed between two guide rollers 8 and then fixedly wound onto the rotating rod 4. The corner plates 7 on both sides and the two guide rollers 8 are used to block and limit the old belt, preventing it from deviating during winding and recycling. At the same time, the two guide rollers 8 roll and squeeze both sides of the old belt, which can crush and remove coal and other materials attached to the old belt, effectively improving the cleanliness of the old belt.

[0035] In some embodiments, such as Figures 3 to 5 As shown, the connecting shaft 3 has a slot 9 at one end near the rotating rod 4; both ends of the rotating rod 4 are fixedly connected to a locking plate 10 that cooperates with the slot 9; the locking plate 10 has a through groove 11 at the position corresponding to the slot 9; a fixing pin 12 is inserted into the through groove 11.

[0036] Specifically, the fixing plate 10 at the end of the rotating rod 4 is inserted into the slot 9 on the connecting shaft 3. At this time, the slot 9 is aligned with the through groove 11 on the fixing plate 10. Then, the fixing pin 12 is passed through the through groove 11 to fix the fixing plate 10 into the slot 9, and the two ends of the rotating rod 4 are fixedly connected to the connecting shafts 3 on both sides.

[0037] After the old belt is wound onto the rotating rod 4, use a forklift or crane to lift both ends of the rotating rod 4. At this time, pull out the fixing pin 12 inside the through groove 11 to separate the rotating rod 4 from the connecting shaft 3, so that the rotating rod 4 can be removed from the connecting shaft 3 and the wound old belt can be removed, which improves the convenience of operation.

[0038] Furthermore, such as Figure 3 As shown, the outer edge of the connecting shaft 3 away from the rotating rod 4 is provided with multiple stepped holes; the middle part of the connecting shaft 3 away from the rotating rod 4 is provided with multiple grooves 13 and multiple protrusions 14; the grooves 13 and the protrusions 14 are alternately arranged, and the shape and structure of the grooves 13 and the protrusions 14 are matched.

[0039] Specifically, the end of the connecting shaft 3 away from the rotating rod 4 is provided with multiple grooves 13 and multiple protrusions 14 are fixedly connected around it; the structural shape of the protrusions 14 matches the structural shape of the grooves 13, so that the protrusions 14 can be inserted into the grooves 13; the outer edge of the first transmission rod of the drive mechanism 5 near the connecting shaft 3 is also provided with stepped holes, and the first transmission rod near the connecting shaft 3 is also provided with multiple grooves 13 and multiple protrusions 14.

[0040] When the connecting shaft 3 is fixedly connected to the drive mechanism 5, the stepped hole on the connecting shaft 3 is aligned with the stepped hole of the first transmission rod of the drive mechanism 5. At this time, the protrusion 14 on the connecting shaft 3 is aligned and engaged with the groove 13 on the first transmission rod, and the groove 13 on the connecting shaft 3 is aligned and engaged with the protrusion 14 on the first transmission rod. The connecting shaft 3 is fixedly connected to the first transmission rod of the drive mechanism 5 by passing a bolt through the stepped hole. Through the cooperation of the protrusion 14 and the groove 13, the torque borne by the bolt is reduced, the bolt breakage is reduced, and the stability of the rotation of the connecting shaft 3 is improved.

[0041] In some embodiments, such as Figures 4 to 6 As shown, a sleeve 15 is slidably installed on the outer ring of the rotating rod 4; a fixing groove 16 is provided on both sides of the sleeve 15; a pressure strip 17 for pressing down and fixing the old belt is bolted inside the fixing groove 16.

[0042] Specifically, the rotating rod 4 has sliding grooves on both sides that are parallel to the axis of the rotating rod 4, and the inner ring of the sleeve 15 has protrusions that match the sliding grooves on both sides; the two ends of the pressure strip 17 are fixedly installed into the fixing grooves 16 on both sides of the sleeve 15 by screws.

[0043] The cut end of the old belt is wound around the outer ring of the sleeve 15, and then the pressure strip 17 is fixedly installed in the fixing groove 16. The pressure strip 17 is used to press and fix the end of the old belt to the outer ring of the sleeve 15, which facilitates the winding of the old belt. The rotating rod 4 rotates, which drives the sleeve 15 to rotate, and the old belt is wound around the outer ring of the sleeve 15. When the wound old belt is taken out, the rotating rod 4 is pulled out from the inside of the sleeve 15. The inner ring of the old belt roll is supported and fixed by the sleeve 15 and the pressure strip 17, which reduces the possibility of the old belt roll spreading out when stacked and improves the stability of the old belt roll.

[0044] In some embodiments, such as Figure 1 , Figures 7 to 8As shown, a support plate 18 is fixedly connected to the bottom surface of the base frame 1; the middle part of the support plate 18 is aligned with the rotating rod 4; trapezoidal support platforms 19 are slidably installed at both ends of the top surface of the support plate 18; a bidirectional screw 20 is rotatably installed at the middle of the top surface of the support plate 18, and the end of the bidirectional screw 20 rotatably penetrates the outer wall of the base frame 1; the two ends of the bidirectional screw 20 are threadedly engaged with the trapezoidal support platforms 19 on both sides.

[0045] Specifically, guide rails are fixed to both sides of the top surface of the support plate 18, and guide grooves matching the guide rails are opened twice on the bottom surface of the trapezoidal support platform 19. The inclined surface of the trapezoidal support platform 19 faces the rotating rod 4, and the two trapezoidal support platforms 19 are located on both sides of the rotating rod 4 respectively. The bottom of the trapezoidal support platform 19 is provided with screw holes matching the bidirectional screw 20.

[0046] Rotating the bidirectional screw 20 drives the trapezoidal support 19 to slide along the guide rail on the top surface of the support plate 18, so that the trapezoidal support 19 on both sides are closer or farther apart.

[0047] After the old belt is wound onto the outer ring of the sleeve 15, the double-acting screw 20 is rotated to drive the trapezoidal support platforms 19 on both sides. The inclined surfaces of the trapezoidal support platforms 19 on both sides contact the bottom sides of the old belt roll, lifting and fixing the old belt roll, making it easier for workers to disassemble the rotating rod 4 and preventing the old belt roll from falling.

[0048] Furthermore, such as Figures 7 to 8 As shown, the inclined surface of the trapezoidal support 19 is evenly provided with a plurality of arc-shaped guide grooves 21; a horizontal guide groove plate 22 is fixedly connected to the bottom of the arc-shaped guide groove 21.

[0049] Specifically, the inclined surfaces of the trapezoidal support platforms 19 on both sides contact the bottom sides of the old belt roll, lifting and fixing the old belt roll. At this time, the workers insert the straps into the arc-shaped guide grooves 21 of the trapezoidal support platforms 19. Since the bottom of the arc-shaped guide grooves 21 is provided with guide plates 22, the straps are guided by the guide plates 22 after reaching the bottom of the arc-shaped guide grooves 21, and change to a horizontal state, so that the straps can smoothly reach the guide plates 22 on the other side, and then go up along the arc-shaped guide grooves 21, so that the straps wrap around the old belt roll. At this time, the two ends of the straps are fixed and tied tightly, thereby fixing and tying the old belt tightly, and effectively preventing the old belt rolls from becoming loose when stacked.

[0050] Working principle: Pass the cut end of the old belt through the two guide rollers 8, then wind the cut end of the old belt around the outer ring of the sleeve 15, and then fix the pressure strip 17 into the fixing groove 16. Use the pressure strip 17 to press and fix the end of the old belt to the outer ring of the sleeve 15.

[0051] Start the drive motor, drive the worm gear to rotate, drive the worm and the second transmission rod to rotate, drive the third transmission rod to rotate through the belt drive, drive the second gear to rotate, drive the first gear and the first transmission rod to rotate, and then drive the connecting shaft 3 to rotate, drive the rotating rod 4 to rotate, and wind the old belt onto the outer ring of the sleeve 15 to form an old belt roll.

[0052] At this time, rotating the bidirectional screw 20 drives the trapezoidal support platforms 19 on both sides. The inclined surfaces of the trapezoidal support platforms 19 on both sides contact the bottom sides of the old belt roll, lifting and fixing the old belt roll. Insert the strap into the arc-shaped guide groove 21 of the trapezoidal support platform 19. Since the bottom of the arc-shaped guide groove 21 is provided with a guide plate 22, the strap reaches the bottom of the arc-shaped guide groove 21 and is guided by the guide plate 22, changing to a horizontal state. This allows the strap to smoothly reach the guide plate 22 on the other side and then go up along the arc-shaped guide groove 21, so that the strap passes around the old belt roll. At this time, fix and tighten both ends of the strap, thereby fixing and tightening the old belt.

[0053] Pull out the fixing pin 12 inside the through groove 11 to separate the rotating rod 4 from the connecting shaft 3. Remove the rotating rod 4 from the connecting shaft 3 and pull it out from the sleeve 15. Then use a forklift to transport the old belt roll to the storage yard for stacking. This not only facilitates the recycling of waste belts, but also greatly reduces the space occupied in the storage area. Furthermore, the neat stacking is conducive to the later recycling.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
