Description

Technical Field

[0001] This invention belongs to the technical field of chain processing and conveying equipment, specifically a chain processing and conveying system for coal mines. Background Technology

[0002] Coal mines use scraper conveyors during the mining process. Scraper conveyors can transport the mined coal in equal quantities, thereby reducing the workload of workers. When transporting coal using a scraper conveyor, the scraper is moved by the movement of a chain to assist in the transportation of coal.

[0003] Chains need to be conveyed and transferred during production or after production. To save space during transfer, they are usually wound up. Existing winding machines used for chain conveying and transfer can only wind the chain onto the winding roller and convey it. They cannot easily and effectively unload and move the wound roller, nor can they automatically and evenly distribute the chain on the surface of the winding roller, requiring manual assistance. This results in performance defects in the winding machine. Therefore, improvements are needed to address the current situation. Summary of the Invention

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

[0028] Example 1, by Figures 1 to 9 The invention comprises two crossbeams 1, with a support plate 2 fixedly installed between opposite sides of the two crossbeams 1. Support rods 3 are fixedly connected to the top of each of the two crossbeams 1. A load-carrying transmission drum 4 is rotatably connected between the two support rods 3. Inverted L-shaped rotating rods 5 are symmetrically rotatably connected to the middle of opposite sides of the two crossbeams 1. A support drum 6 is rotatably connected between the tops of the two inverted L-shaped rotating rods 5. A take-up roller 7 with an I-beam structure is provided between the support drum 6 and the load-carrying transmission drum 4. Separation adjustment components are provided on opposite sides of the two crossbeams 1. One end of each joint component rotates with the upper part of two inverted L-shaped rotating rods 5. A first motor 8 is installed on one side of one of the crossbeams 1. The output end of the first motor 8 is connected to two separate adjustment components. Two rollers 9 are installed on opposite sides of the two crossbeams 1. A moving push handle 10 is fixedly installed on the top of each of the two crossbeams 1. A uniformly arranged transmission component 11 is fixedly installed between the top ends of the two crossbeams 1. An n-shaped plate 12 is installed on the top of the uniformly arranged transmission component 11. A reciprocating moving component 13 is installed on the top of the n-shaped plate 12. The lower part of the moving part 13 is connected to the uniformly arranged transmission parts 11. A second motor 14 is installed on one side of one of the crossbeams 1. The output end of the second motor 14 is connected to one end of the uniformly arranged transmission parts 11 and one end of the load-bearing transmission drum 4. Both separation adjustment parts include a moving groove 15. The moving groove 15 is opened on the opposite side of the two crossbeams 1. The interior of each of the two moving grooves 15 is rotatably connected to a threaded rod 16. The surface of each of the two threaded rods 16 is threadedly connected to a moving block 17. The top of each of the two moving blocks 17 is rotatably connected to two inverted... The L-shaped rotating rod 5 is rotatably connected to the connecting arm 18; the bottom of the two moving slots 15 is provided with through slots 19 extending to the bottom of the two crossbeams 1; the middle of the support plate 2 is provided with an extension slot 22; one end of the two threaded rods 16 is fixedly connected to a worm gear 20; the two worm gears 20 extend to the bottom of the two crossbeams 1 through the two through slots 19; the bottom of the two crossbeams 1 is rotatably connected to a worm 21 that meshes with the two worm gears 20; one end of the worm 21 is fixedly connected to the output end of the first motor 8, so that the winding roller 7 can be effectively adjusted downwards;

[0029] The rotation of the load-carrying drive drum 4 causes the rotating load-carrying drive drum 4 to cooperate with the support drum 6, thereby rotating and adjusting the winding roller 7. The rotating winding roller 7 will wind up the chain. After the winding roller 7 has finished winding, the first motor 8 is started, causing the worm gear 21 to drive the two worm wheels 20 to rotate. The rotation of the two worm wheels 20 will drive the two threaded rods 16 to rotate. The rotation of the two threaded rods 16 will cause the moving block 17 to move on its surface, pulling the connecting arm 18 to move. The movement of the connecting arm 18 will pull the inverted L-shaped rotating rod 5 to rotate. The rotation of the inverted L-shaped rotating rod 5 will drive the support drum 6 to rotate and move downward, thereby causing the winding roller 7 between the load-carrying drive drum 4 and the support drum 6 to move downward to the surface of the support plate 2. Finally, the lowered support drum 6 will extend into the interior of the extension groove 22, so that the winding roller 7 can roll and move on the surface of the support plate 2.

[0030] In Example 2, based on Example 1, an unloading ramp 23 is rotatably connected between one end of the two crossbeams 1 on opposite sides. A connecting rod 24 is fixedly connected to the bottom of the unloading ramp 23. A resetter 25 connected to the end of the connecting rod 24 is installed at one end of each of the two crossbeams 1 on opposite sides. The two resetters 25 include a sleeve 26, a T-shaped rod 27, and a reset spring 28. The sleeve 26 is rotatably connected to one end of each of the two crossbeams 1 on opposite sides. The T-shaped rod 27 is movably inserted into the inside of the sleeve 26. The reset spring 28 is sleeved on the surface of the T-shaped rod 27 located inside the sleeve 26. One end of each T-shaped rod 27 is rotatably connected to the end of the connecting rod 24, thereby effectively unloading the winding roller 7.

[0031] After the take-up roller 7 moves down to the surface of the support plate 2, it is slowly moved from the surface of the support plate 2 to the unloading ramp 23 by rolling the take-up roller 7. The compression of the take-up roller 7 will cause the unloading ramp 23 to rotate and tilt and contact the ground. The rotation of the unloading ramp 23 will pull the T-shaped rod 27 to move and compress the return spring 28. Then the take-up roller 7 is rolled on the unloading ramp 23 to unload the take-up roller 7. After the take-up roller 7 is removed from the unloading ramp 23, the elastic force of the return spring 28 will cause the unloading ramp 23 to rotate and move upward to reset.

[0032] In Example 3, based on Example 1, a first sprocket 29 is fixedly connected to one end of the support transmission drum 4, a transmission pinion 30 is fixedly connected to the output end of the second motor 14, a second sprocket 31 is fixedly connected to one side of the transmission pinion 30, and a chain 32 is installed between the second sprocket 31 and the first sprocket 29, so that transmission can be effectively carried out to make the winding roller 7 rotate and wind up the chain;

[0033] By starting the second motor 14, the transmission pinion 30 drives the second sprocket 31 to rotate. The rotation of the second sprocket 31 drives the first sprocket 29 to rotate. The rotation of the first sprocket 29 drives the first sprocket 29 to rotate through the chain 32. The rotation of the first sprocket 29 drives the load transmission drum 4 to rotate. The rotating load transmission drum 4 cooperates with the support drum 6 to make the take-up roller 7 rotate. The rotating take-up roller 7 will wind up the chain.

[0034] The uniformly arranged transmission components 11 include an inverted n-shaped plate 33 fixedly connected between the top ends of the two crossbeams 1. Two threaded shafts 34 are rotatably connected to the inner side of the inverted n-shaped plate 33. One end of each threaded shaft 34 extends to the outside of one end of the inverted n-shaped plate 33 and is fixedly connected to two meshing transmission gears 35. One end of one of the transmission gears 35 is fixedly connected to a large transmission gear 36. The large transmission gear 36 meshes with a small transmission gear 30, thereby enabling effective transmission.

[0035] The starting of the second motor 14 will cause the transmission pinion 30 to drive the transmission gear 36 to rotate. The rotation of the transmission gear 36 will cause the two threaded shafts 34 to rotate synchronously relative to each other through the two meshing transmission gears 35.

[0036] In Embodiment Four, based on Embodiment Three, the n-shaped plate 12 is fixedly connected between the two ends of the top of the inverted n-shaped plate 33. The reciprocating moving component 13 includes a horizontal groove 37 formed on the top of the n-shaped plate 12. Two sliding rods 38 are fixedly connected inside the horizontal groove 37. A slider 39 is slidably installed between the two sliding rods 38. A fixing pin 40 is fixedly connected to the upper part of one side of the slider 39. A connecting rod 41 is rotatably connected to the surface of the fixing pin 40. A transmission block 42 is fixedly connected to the bottom of the connecting rod 41. Both sides of the transmission block 42 are provided with arc-shaped threaded grooves 43 that match the two threaded shafts 34. The transmission block 42 is connected to the two threaded shafts 34 through the two arc-shaped threaded grooves 43, thereby enabling effective transmission and movement. The top end of the slider 39 is rotatably connected to a rotating pin 44. The upper part of the rotating pin 44 is fixedly connected to a grooved plate 45 and a fixing strip 47. The top of the connecting rod 41 is fixedly connected to a toggle pin 46 located inside the grooved plate 45. The top of one end face of the slider 39 is fixedly connected to a fixing plate 48. A deflection adjustment spring 49 is fixedly connected between one end of the fixing plate 48 and one end of the fixing strip 47. The top of the toggle pin 46 is fixedly connected to a U-shaped transmission box 50. A roller 51 is rotatably installed on one end of the inner side of the U-shaped transmission box 50. Both ends of the top of the n-shaped plate 12 are fixedly connected to fixing stop pins 52. One end of the fixing strip 47 is located between the two fixing stop pins 52, so that the transmission block 42 can effectively reciprocate and adjust.

[0037] When the two threaded shafts 34 rotate synchronously relative to each other, the transmission block 42 contacts one of the rotating threaded shafts 34 through the arc-shaped threaded groove 43. This causes the transmission block 42 to move through the arc-shaped threaded groove 43 and the rotating threaded shaft 34. The movement of the transmission block 42, through the connecting rod 41 and the fixing pin 40, drives the slider 39 to slide on the surface of the two sliding rods 38. The movement of the slider 39 drives the fixing bar 47 at its top to move. When the moving fixing bar 47 contacts one of the fixing stop pins 52, the fixing bar 47 rotates and rotates through the rotating pin 44. The rotating groove plate 45 is driven to rotate and pull the deflection adjusting spring 49. The tension of the deflection adjusting spring 49 causes the rotating groove plate 45 to move the actuating pin 46, which in turn causes the connecting rod 41 to rotate. The rotation of the connecting rod 41 causes the transmission block 42 to deflect and contact another rotating threaded shaft 34 through the arc-shaped threaded groove 43. At this time, the transmission block 42 will move back through the other rotating threaded shaft 34. The limiting and blocking of the two fixed stop pins 52 and the relatively rotating threaded shafts 34 will cause the transmission block 42 to continuously reciprocate.

[0038] The continuous reciprocating movement of the transmission block 42 drives the U-shaped transmission box 50 and the roller 51 to reciprocate continuously via the rotating pin 44 and the actuating pin 46. The chain is placed inside the U-shaped transmission box 50 and on the surface of the roller 51, and then the chain is connected to the surface of the take-up roller 7. The rotating take-up roller 7 and the reciprocating movement of the U-shaped transmission box 50 will make the chain evenly wound on the surface of the take-up roller 7.

[0039] This chain processing and conveying system for coal mines can effectively wind and convey chains, and can stably and conveniently unload and move the wound chains, thereby effectively improving the convenience of chain processing and conveying. At the same time, this conveying system has a uniform arrangement structure, which can evenly arrange the winding connections on the surface of the winding roller, making the chain processing, conveying and winding more stable and reliable. Furthermore, this chain processing and conveying system for coal mines has a simple structural design, is easy to use and operate, and its performance can meet the needs of chain processing and conveying in coal mines.
