Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of automatic correction devices, and in particular to an automatic correction device for preventing the wire rope from becoming tangled in a coal mine winch. Background Technology
[0002] The automatic anti-tangling device for wire ropes in coal mine winches is a key piece of equipment used in coal mine production to ensure the orderly winding of the wire ropes and prevent tangling. It monitors and adjusts the operating status of the winch wire ropes in real time, effectively improving the safety and stability of the coal mine transportation system. With continuous technological development and innovation, its performance and reliability will continue to improve, providing a strong guarantee for the efficient and safe development of the coal mining industry.
[0003] Existing coal mine winches use anti-detangling and guiding devices (mainly consisting of guide wheels and support wheels) to guide the wire rope to wind around the winch drum along a predetermined trajectory. The support drives the guide wheels to move, changing the wire rope's entry angle and preventing it from becoming tangled on the drum. This automatically corrects the wire rope's deviation. When the winch is working and the wire rope is being wound up or down, the guide wheels passively rotate around their own axis under the action of friction. In this passive rotation, the speed of the guide wheels depends entirely on the friction of the wire rope. Due to the asynchronous speeds, sliding friction can easily occur between the two, causing wear on the wire rope's surface coating. At the same time, the wear-resistant layer of the guide wheel groove is shortened because it is constantly subjected to sliding friction. Utility Model Content

The front and rear ends of the correction frame are respectively threadedly connected to the slide bar and the lead screw.
[0009] As a further embodiment of this utility model, a brush and a clamping frame are provided on the side of the winch body away from the correction frame.

[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. When the winch body drives the drum to rotate and wind up the wire rope, the wire rope first passes through the anti-tangling body, which is fixed between the two side plates of the winch body. This pre-guides the wire rope to initially arrange itself in an orderly manner along the drum axis, reducing initial deviation. Subsequently, the wire rope enters the clamping groove of the straightening frame. The rope-supporting wheel and the rope-guide post in the clamping groove cooperate to clamp the wire rope vertically. The drive motor and the drive unit of the winch body start synchronously, driving the drive gear to rotate. Through the toothed belt drive, the driven gear rotates synchronously, thereby driving the rope-supporting wheel and the rope-guide post to rotate synchronously in the opposite direction. The rotation speed can be precisely matched with the winding speed of the wire rope. With the help of friction, the wire rope moves smoothly for winding. This active drive mode can provide a stable and controllable guiding force for the wire rope. The electric drive can ensure that the rope support wheel, the guide post and the wire rope are always in a rolling friction state. The friction coefficient is stable within a certain range. Compared with the sliding friction caused by asynchronous speed when the rotation is passive, it can reduce the wear of the coating on the surface of the wire rope, extend the service life of the wheel groove of the rope support wheel and the guide post, and significantly reduce the equipment maintenance cost.
[0014] 2. When the winch body winds up the wire rope, the brush on the side away from the straightening frame works under the drive of a dual-shaft motor. The dual-shaft motor drives the drive shafts at both ends to rotate. The drive shafts are fixedly connected to the mounting frame, which in turn drives the brush to rotate. The brush is in contact with the surface of the wire rope during the winding process. As the wire rope winds up, the brush cleans the coal dust, oil stains and other impurities attached to its surface to prevent the accumulation of impurities from affecting the winding accuracy of the wire rope. During the brush cleaning of the wire rope, the cleaned impurities fall into the feed hopper below under the action of gravity. The feed hopper is fixed between the side plates of the winch body and located directly below the drum. It can collect the cleaned impurities and guide them into the collection box in the middle of the frame through the discharge pipe at the bottom. This achieves centralized treatment of impurities, keeps the environment around the winch clean, and prevents impurities from adhering to the wire rope again and affecting the winding.

[0024] Reference Figures 1-5An automatic anti-tangling device for wire rope of a coal mine winch includes a frame 1 and a correction frame 5. A winch body 101 is fixedly mounted on the top of the frame 1. A drum 103 is rotatably mounted between two side plates in the middle of the winch body 101. Several anti-tangling bodies 102 are provided on one side of the drum 103, with both ends of the anti-tangling bodies 102 fixedly connected to the two side plates of the winch body 101. The correction frame 5 is located on one side of the anti-tangling bodies 102, and a through groove 501 is provided on one side of the correction frame 5. The correction frame 5 includes a rope-supporting wheel 502, a rope guide post 503, a driving gear 504, a driven mass, a toothed belt 506, and a drive motor 507. The rope-supporting wheel 502 and the rope guide post 503 are both located inside the groove 501, and both ends are rotatably connected to the side plate of the correction frame 5. The toothed belt 506 is sleeved between the driving gear 504 and the driven gear 505. The drive gear 504, driven gear 505, toothed belt 506, and drive motor 507 are all located inside one side of the straightening frame 5. One end of the rope-supporting wheel 502 passes through the side plate of the straightening frame 5 and is fixedly connected to the drive gear 504. The drive motor 507 is located on one side of the drive gear, and its output end is fixedly connected to the shaft of the drive gear 504. The drive motor 507 is fixedly installed inside the straightening frame 5. The guide rope column 503 is located on the top of the rope-supporting wheel 502. One end of the guide rope column 503 passes through the side plate of the straightening frame 5 and is fixedly connected to the driven gear 505. Two sets of pressure sensing columns 509 are provided on both the front and rear sides of the clamping groove 501. The pressure sensing columns 509 are fixedly connected to the top of one end of the straightening frame 5. An infrared sensor 508 is provided between one set of pressure sensing columns 509. The infrared sensor 508 is fixedly installed on the top of one end of the straightening frame 5.
[0025] In use, when the winch body 101 drives the drum 103 to rotate and wind up the wire rope, the wire rope first passes through the anti-tangling body 102, which is fixed between the two side plates of the winch body 101. This pre-guides the wire rope to initially arrange itself in an orderly manner along the axial direction of the drum 103, reducing initial deviation. Subsequently, the wire rope enters the clamping groove 501 of the straightening frame 5. The rope-supporting wheel 502 and the rope-guide post 503 in the clamping groove 501 cooperate to clamp the wire rope vertically. The drive motor 507 starts synchronously with the drive unit of the winch body 101. The active drive mechanism rotates the drive gear 504, which in turn drives the driven gear 505 to rotate synchronously via the toothed belt 506. This, in turn, drives the rope-supporting wheel 502 and the rope-guide post 503 to rotate synchronously in opposite directions. Their rotational speed can precisely match the winding speed of the wire rope. Friction assists the wire rope in moving smoothly during winding. This active drive mode provides a stable and controllable guiding force for the wire rope. Pressure sensing posts 509 on both sides of the clamp 501 and the infrared sensor 508 on top monitor the winding status of the wire rope in real time. If the wire rope deviates during winding, it touches the pressure sensing post 509, causing a change in its pressure value. Simultaneously, the infrared sensor 508 detects the trajectory deviation, and both transmit signals to the control system, providing a basis for subsequent correction. This part, through the active drive rope-supporting wheel 502 and the rope-guide post 503 working together with the detection components, ensures that the wire rope maintains a stable trajectory in the early stages of winding, reducing the risk of rope tangling. Electric drive ensures that the rope-supporting wheel 502, the rope-guide post 503 and the wire rope are always in a rolling friction state, and the friction coefficient is stable within a certain range. Compared with the sliding friction caused by asynchronous rotation speed during passive rotation, it can reduce the wear of the coating on the surface of the wire rope, extend the service life of the wheel grooves of the rope-supporting wheel 502 and the rope-guide post 503, and significantly reduce the equipment maintenance cost.
[0026] In this embodiment, a first side frame 2 and a second side frame 3 are provided on one side of the winch body 101. The first side frame 2 and the second side frame 3 are both fixedly connected to the top of the frame 1. The second side frame 3 has the same structure as the first side frame 2. A plurality of first cylinders 201 are fixedly connected inside the first side frame 2. A positioning frame 202 is provided on the top of the first side frame 2. The telescopic ends of the plurality of first cylinders 201 are fixedly connected to the bottom of the positioning frame 202. The correction frame 5 is located between the first side frame 2 and the second side frame 3, and a displacement device 4 is provided at its bottom.
[0027] During use, the first side frame 2 and the second side frame 3 support and adjust the height of the straightening frame 5 during the wire rope winding process. If the wire rope diameter or winding position changes, the first cylinder 201 inside the first side frame 2 extends or retracts, driving the positioning frame 202 to rise or fall, thereby adjusting the height of the straightening frame 5 to match the wire rope winding position.
[0028] In this embodiment, the displacement device 4 includes a lead screw 401, a slide bar 402, and a drive motor 403. Both ends of the lead screw 401 are rotatably connected to the inner side of several positioning frames 202. Both ends of the slide bar 402 are fixedly connected to the inner side of several positioning frames 202. The drive motor 403 is fixedly installed on the outer side of the positioning frame 202 of the first side frame 2. The output end of the drive motor 403 is fixedly connected to one end of the lead screw 401. The front and rear ends of the correction frame 5 are respectively threadedly connected to the slide bar 402 and the lead screw 401.
[0029] In use, the displacement device 4 operates according to the instructions of the control system. When the wire rope deviation is detected and horizontal adjustment is required, the drive motor 403 starts and drives the lead screw 401 to rotate. Since the front and rear ends of the correction frame 5 are slidably connected to the slide rod 402 and threadedly connected to the lead screw 401 respectively, the rotation of the lead screw 401 causes the correction frame 5 to move horizontally along the slide rod 402, thereby achieving precise adjustment of the wire rope winding position and ensuring that the wire rope is always correctly wound along the axial direction of the drum 103, avoiding rope tangling caused by position deviation.
[0030] In this embodiment, a brush 6 and a clamping frame 7 are provided on the side of the winch body 101 away from the correction frame 5. A dual-axis motor 701 is fixedly connected inside the clamping frame 7. Both ends of the dual-axis motor 701 are fixedly connected to a drive shaft 702. A mounting bracket 703 is fixedly connected to the back side of the brush 6 by bolts. Both ends of the mounting bracket 703 are inserted into the grooves of the clamping frame 7. The drive shafts 702 pass through the grooves and are rotatably connected to the clamping frame 7. Both ends of the mounting bracket 703 are fixedly connected to several drive shafts 702.
[0031] During use, when the winch body 101 winds up the wire rope, the brush 6 on the side away from the straightening frame 5 works under the drive of the dual-shaft motor 701. The dual-shaft motor 701 drives the drive shafts 702 at both ends to rotate. The drive shafts 702 are fixedly connected to the mounting frame 703, which in turn drives the brush 6 to rotate. The brush 6 is in contact with the surface of the wire rope during the winding process. As the wire rope is wound up, the brush 6 cleans the coal dust, oil stains and other impurities attached to its surface to prevent the accumulation of impurities from affecting the winding accuracy of the wire rope.
[0032] In this embodiment, the back side of the clamping frame 7 is provided with a plurality of second cylinders 704 and a frame column 8. The plurality of second cylinders 704 are fixedly connected to the top of the frame column 8, the bottom of the frame column 8 is fixedly connected to the top of the frame 1, the telescopic end of the second drive cylinder is fixedly connected to the back side of the clamping frame 7, and the brush 6 is located between the side plates of the winch body 101 and close to the drum 103.
[0033] When the brush 6 shows signs of aging and shedding after prolonged use, the worker can remove the bolts on the back of the mounting bracket 703 to separate the brush 6 from the bracket 703, facilitating regular replacement and cleaning. The second cylinder 704 on the back of the clamping frame 7 can adjust the extension and retraction amount according to the length of the wire rope, changing the contact distance between the clamping frame 7, the brush 6, and the wire rope. This ensures effective cleaning while preventing excessive wear on the wire rope. This part cleans the wire rope, reducing interference from impurities during winding and ensuring smooth winding.
[0034] In this embodiment, the bottom of the brush 6 is provided with a feeding hopper 104. The feeding hopper 104 is fixedly installed between the side plates of the winch body 101 and located directly below the drum 103. The discharge pipe of the feeding hopper 104 is connected through to the top of the frame 1. A collection box 105 is slidably connected in the middle of the frame 1 and is located at the bottom of the feeding hopper 104.
[0035] During use, as the brush 6 cleans the wire rope, the cleaned impurities fall into the lower hopper 104 under gravity. The hopper 104 is fixed between the side plates of the winch body 101 and located directly below the drum 103. It can collect the cleaned impurities and guide them into the collection box 105 in the middle of the frame 1 through the discharge pipe at the bottom. The collection box 105 is slidably placed in the empty groove in the middle of the frame 1. When a certain amount of impurities are collected, the collection box 105 can be pulled out for cleaning, realizing the centralized treatment of impurities, keeping the environment around the winch clean, and preventing impurities from adhering to the wire rope again and affecting the winding.
[0036] As can be seen from the above description, the above embodiments of this utility model achieve the following technical effects: During the process of the winch body 101 driving the drum 103 to wind the wire rope, each structure operates in coordination according to its function to form a complete anti-tangle system: First, the wire rope is initially guided by the anti-tangle body 102 and arranged in an orderly manner along the axis of the drum 103 to reduce the initial offset; then it enters the clamping groove 501 of the correction frame 5, and the rope support wheel 502 and the rope guide column 503 rotate synchronously in opposite directions under the drive of the transmission motor 507 (through the driving gear 504, toothed belt 506, and driven gear 505) to form a clamping guide with a rotation speed matching the winding speed. The rolling friction helps the wire rope move smoothly, and at the same time, the pressure sensing columns 509 on both sides of the clamping groove 501 and the infrared sensor 508 on the top monitor the offset in real time and transmit the signal to the control system. When adjustment is required, the first cylinders 201 of the first side frame 2 and the second side frame 3 drive the positioning frame 202 to rise and fall, adapting to changes in the wire rope diameter or winding position. The drive motor 403 of the displacement device 4 drives the lead screw 401 to rotate, causing the correction frame 5 to move horizontally along the slide bar 402, achieving precise correction and ensuring that the wire rope is wound axially along the drum 103. At the same time, the brush 6 on the side away from the correction frame 5 rotates under the drive of the dual-axis motor 701 to clean the coal dust and oil stains on the surface of the wire rope. The second cylinder 704 on the back of the clamping frame 7 adjusts the contact distance of the brush 6 to balance cleaning and wear. The cleaned impurities are collected in the collection box 105 through the hopper 104 for centralized treatment, avoiding secondary pollution. The entire process, through the closed-loop cooperation of "guidance-drive-monitoring-adjustment-cleaning", ensures the orderly winding of the wire rope, effectively preventing rope tangling. Moreover, the winding and unwinding principles of the wire rope are consistent, and each structure operates according to the same logic during unwinding, maintaining the stability and safety of the wire rope winding and unwinding throughout the process.
[0037] 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. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
