It is primarily installed at the rear or a specific location on tracked equipment. Through its internal mechanical structure, it automatically winds and releases cables, ensuring that the cables remain orderly and tangle-free during movement or operation, maintaining an appropriate distance from the equipment to avoid being crushed by the tracks or scratched by other obstacles. This device simplifies cable management, reduces operator workload, and extends cable lifespan by preventing cables from being crushed by the tracks or scratched by other obstacles. It also reduces safety hazards caused by tangled, messy, or damaged cables, ensuring the safety of tracked equipment during operation. By reducing potential risks to operators when managing cables, it improves the overall safety of the working environment. The automatic cable reel-in / delivery device plays a crucial role in tracked equipment, not only simplifying cable management and reducing operator workload but also improving equipment efficiency and safety.

[0013] Preferably, a first shaft is fixedly installed at both ends of the rotating rod, a first bushing is rotatably installed on the surface of each of the two first shafts, the two first bushings are fixedly connected to both sides of one end of the support frame, and the ends of the two first shafts that are far apart from each other are respectively fixedly connected to two leveling rollers.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] (1) When the ground soil is uneven, the operator starts the hydraulic cylinder to drive the connecting frame to move down. The connecting frame drives the support frame to rotate downward through the cooperation of the pin and the hollow strip, thereby driving the two leveling rollers to move down to the ground. At the same time, the operator starts the servo motor to drive the worm to rotate. The worm drives the worm wheel to drive the rotating rod to rotate. When the rotating rod rotates, it drives the two first shafts to rotate along the inside of the two first shaft sleeves. When the two first shafts rotate, they drive the two leveling rollers to rotate. The chassis is started to drive the two tracks to move, thereby controlling the device to level the land and allowing the two tracks to be stably supported on the ground to prevent the device from tilting.

[0016] (2) When disassembling a saturated winding drum, the operator starts the drive motor to run in the forward direction. When the drive motor runs in the forward direction, it drives the first bevel gear to rotate. The first bevel gear drives the second shaft to rotate inside the two second shaft sleeves through the second bevel gear. When the second shaft rotates, it drives the two threaded rods to rotate. When the two threaded rods rotate, they drive the two threaded sleeves to move back to back. When the two threaded sleeves move, they both drive the limit block to slide along the inside of the limit groove, which improves the stability of the two threaded sleeves when they move. When the two threaded sleeves move back to back, they drive the two moving rods to move back to back. When the two moving rods move, they both drive the first slider to slide along the inside of the first sliding groove, which improves the stability of the two moving rods when they move. When the two moving rods move back to back, they drive the two first racks to move back to back through the two connecting rods. When the two first racks move back to back, they drive the two second racks to move towards each other through the two transmission gears.

[0017] When the two second racks move towards each other, they drive the two transmission bars to move towards each other. As the transmission bars move, they drive the second sliders to slide along the inside of the second groove, which improves the stability of the two transmission bars when they move. When the two transmission bars move towards each other, they push the two rectangular rods to move upward along the inside of the two rectangular sleeves through the two contact blocks, and at the same time squeeze the two springs. When the two rectangular rods move upward, they drive the two lifting frames to move upward and support the two positioning cylinders, thereby supporting the entire drum. When the two moving rods move backward, they also drive the left moving platform and the right moving platform to move backward, thereby driving the left locking rod and the right locking rod to exit the inside of the two positioning cylinders and release the limit, thus quickly completing the disassembly of the drum.

[0018] (3) When fixing the new drum, the operator places the positioning cylinders at both ends of the new drum on the two lifting frames. Then the operator starts the drive motor to run in reverse. When the drive motor runs in reverse, it drives the two threaded sleeves to move towards each other through the two threaded rods. When the two threaded sleeves move towards each other, they drive the left and right moving platforms to move towards each other through the two moving rods. This causes the left and right locking rods to be inserted into the inside of the two positioning cylinders for limiting installation. At the same time as the two moving rods move towards each other, they also drive the two first racks to move towards each other through the connecting rods. When the two first racks move towards each other, they drive the two second racks to move away from each other through the two transmission gears. When the two second racks move away from each other, they drive the two transmission bars to move away from each other, so that the two transmission bars no longer push the two contact blocks. Under the elastic force of the two springs, the two rectangular rods move down. When the two rectangular rods move down, they drive the two lifting frames away from the two positioning cylinders, so as to avoid the two lifting frames affecting the rotation of the drum. When in use, the operator starts the take-up and unload motor to run in both directions, so that the drum can take up and unload the cable.

[0019] (4) This allows the tracked automatic cable winding and unwinding device to easily disassemble and reassemble the drum, and can level the ground to avoid the device tilting due to uneven ground, thus ensuring the cable winding and unwinding effect. Attached Figure Description

[0031] 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.

[0032] Example 1, by Figures 1 to 8The present invention includes a chassis 1, with tracks 3 mounted on both sides of the chassis 1. A support platform 4 is fixedly mounted on the top of the chassis 1, and a mounting base 5 is fixedly mounted on the top of the support platform 4. Baffles 6 are fixedly mounted on both sides of the top of the support platform 4. A drum 7 is provided in the middle of the upper part of the mounting base 5, and positioning cylinders 11 are fixedly mounted on both ends of the drum 7. A left moving platform 8 is provided on one side of the upper part of the mounting base 5, and a right moving platform 9 is provided on the other side of the upper part of the mounting base 5. A receiver / discharger 10 is fixedly mounted on one side of the left moving platform 8, and a left locking rod 12 is fixedly mounted on the output end of the receiver / discharger 10. A right locking rod 13 is rotatably mounted on one side of the left moving platform 8. Lifting frames 14 are provided on the surfaces of the two positioning cylinders 11. A fixing frame 15 is fixedly mounted in the middle of the top of the inner part of the mounting base 5, and a drive motor 16 is fixedly mounted in the top of the inner part of the fixing frame 15. A mounting groove 2 is opened in the lower part of one end of the chassis 1. 1. A support frame 17 is rotatably mounted inside the mounting slot 21. A hollow strip 24 is fixedly mounted on the inner wall of one end of the support frame 17. A pin 25 is inserted into the hollow strip 24. A connecting frame 26 is fixedly mounted between the two ends of the pin 25. A hydraulic cylinder 22 is fixedly mounted at one end of the lower part of the support platform 4. The top of the connecting frame 26 is fixedly connected to the transmission end of the hydraulic cylinder 22. A protective box 18 is fixedly mounted between one end of the support frame 17. A protective cover 19 is fixedly mounted on one side of the protective box 18. A servo motor 20 is fixedly mounted inside the protective cover 19. Leveling rollers 2 are provided on both sides of one end of the support frame 17. The output ends of the drive motor 16 and the servo motor 20 are respectively provided with a first transmission assembly and a second transmission assembly. The first transmission assembly is connected to the left moving platform 8, the right moving platform 9 and the two lifting frames 14. The second transmission assembly is connected to the two leveling rollers 2.

[0033] When the ground soil is uneven, the operator activates the hydraulic cylinder 22 to move the connecting frame 26 downward. The connecting frame 26, through the cooperation of the pin 25 and the hollow strip 24, drives the support frame 17 to rotate downward, thereby moving the two leveling rollers 2 to the ground. At the same time, the operator activates the servo motor 20 to drive the second transmission component to operate. When the second transmission component operates, it drives the two leveling rollers 2 to rotate and starts the chassis 1 to drive the two tracks 3 to move. This allows the device to control the leveling of the ground, so that the two tracks 3 can be stably supported on the ground and prevent the device from tilting.

[0034] When disassembling the fully wound drum 7, the operator starts the drive motor 16 to run in the forward direction. When the drive motor 16 runs in the forward direction, it drives the first transmission component to run in the forward direction. When the first transmission component runs in the forward direction, it drives the two lifting frames 14 to move upward and support the two positioning cylinders 11, thereby lifting the drum 7 as a whole. At the same time, the first transmission component also drives the left locking rod 12 and the right locking rod 13 to exit the interior of the two positioning cylinders 11 and release the limit, thereby quickly completing the disassembly of the drum 7.

[0035] When fixing the new drum 7, the operator places the positioning cylinders 11 at both ends of the new drum 7 on the two lifting frames 14. Then, the operator starts the drive motor 16 to run in reverse. When the drive motor 16 runs in reverse, it drives the first transmission component to run in reverse. When the first transmission component runs in reverse, it drives the left locking rod 12 and the right locking rod 13 to be inserted into the two positioning cylinders 11 for limiting installation. At the same time, the first transmission component runs in reverse, driving the two rectangular rods 51 to move down, so as to prevent the two lifting frames 14 from affecting the rotation of the drum 7. When in use, the operator starts the take-up and unload motor 10 to run in both directions, so as to drive the drum 7 to take up and unload the cable. This allows the tracked automatic take-up and unload cable device to easily disassemble and assemble the drum 7, and can level the ground to avoid the overall tilt of the device caused by uneven ground, thus ensuring the effect of cable take-up and unloading.

[0036] In Embodiment 2, based on Embodiment 1, the first transmission assembly includes a first bevel gear 23, which is fixedly mounted on the output end of the drive motor 16. A second bevel gear 32 is meshed with one side of the surface of the first bevel gear 23. A second shaft 33 is fixedly mounted in the middle of the second bevel gear 32. Two second bushings 34 are rotatably mounted on the surface of the second shaft 33, and the lower parts of the two second bushings 34 are fixedly connected to the inner bottom of the mounting base 5. Threaded rods 35 are fixedly mounted at both ends of the second shaft 33. The ends of the two threaded rods 35 that are far apart from each other are rotatably connected to the inner walls of both ends of the mounting base 5. The thread directions of the two threaded rods 35 are opposite. Both threaded rods 35 are threadedly connected to threaded sleeves 36. Limiting blocks 37 are fixedly installed at the bottom of both threaded sleeves 36. Limiting grooves 38 are formed on both sides of the bottom of the mounting base 5, and the two limiting blocks 37 are slidably installed inside the two limiting grooves 38. Moving rods 39 are fixedly installed on the top of both threaded sleeves 36. The tops of the two moving rods 39 are fixedly connected to the bottoms of the left moving platform 8 and the right moving platform 9, respectively. First sliders 40 are fixedly installed on the upper parts of both sides of the two moving rods 39. Openings are formed on both sides of the top surface of the mounting base 5, and first sliding grooves 41 are formed on the inner walls of both sides of the two openings. Four first sliders 40... The four first slide grooves 41 are slidably installed inside each of the four sliding rods 39. A connecting rod 42 is fixedly installed on the lower part of the moving rod 39 near the drive motor 16. A first rack 43 is fixedly installed at the end of each connecting rod 42 that is close to each other. A transmission gear 44 is meshed with the upper side of each first rack 43. A positioning frame 45 is rotatably installed on one side of each transmission gear 44. The bottom of each positioning frame 45 is fixedly connected to the inner bottom of the mounting base 5. A second rack 46 is meshed with the upper part of each transmission gear 44. A transmission bar 47 is fixedly installed on the top of each of the two second racks 46. Second sliders 48 are fixedly installed on both sides of each transmission bar 47. Two second sliding grooves 49 are respectively opened on the inner walls of both sides of the mounting base 5, and four second sliders 48 are slidably installed inside the four second sliding grooves 49 respectively; the top of the transmission bar 47 is closely attached to the contact block 50, and the top of the two contact blocks 50 is fixedly installed with a rectangular rod 51. The two sides of the top of the mounting base 5 are fixedly installed with rectangular sliding sleeves 52. The two rectangular rods 51 are respectively inserted into the inside of the two rectangular sliding sleeves 52. The top of the two rectangular rods 51 is fixedly connected to the bottom of the two lifting frames 14 respectively. The surface of the two rectangular rods 51 is fitted with a spring 53. The two ends of the two springs 53 are fixedly connected to the contact block 50 and the rectangular sliding sleeve 52 respectively.

[0037] When disassembling the saturated winding drum 7, the operator starts the drive motor 16 to run in the forward direction. When the drive motor 16 runs in the forward direction, it drives the first bevel gear 23 to rotate. The first bevel gear 23 drives the second shaft 33 to rotate inside the two second shaft sleeves 34 through the second bevel gear 32. When the second shaft 33 rotates, it drives the two threaded rods 35 to rotate. When the two threaded rods 35 rotate, they drive the two threaded sleeves 36 to move backward. When the two threaded sleeves 36 move, they both drive the limiting block 37 to slide along the inside of the limiting groove 38, which improves the stability of the two threaded sleeves 36 when they move backward. When the two threaded sleeves 36 move backward, they drive the two moving rods 39 to move backward. When the two moving rods 39 move backward, they both drive the first slider 40 to slide along the inside of the first sliding groove 41, which improves the stability of the two moving rods 39 when they move backward. When the two moving rods 39 move backward, they drive the two first racks 43 to move backward through the two connecting rods 42. When the two first racks 43 move backward, they drive the two second racks 46 to move towards each other through the two transmission gears 44.

[0038] When the two second racks 46 move toward each other, they drive the two transmission bars 47 to move toward each other. When the transmission bars 47 move, they drive the second sliders 48 to slide along the inside of the second grooves 49, which improves the stability of the two transmission bars 47 when they move. When the two transmission bars 47 move toward each other, they push the two rectangular rods 51 to move upward along the inside of the two rectangular sleeves 52 through the two contact blocks 50, and at the same time squeeze the two springs 53. When the two rectangular rods 51 move upward, they drive the two lifting frames 14 to move upward and support the two positioning cylinders 11, thereby supporting the drum 7 as a whole. When the two moving rods 39 move backward, they also drive the left moving platform 8 and the right moving platform 9 to move backward.

[0039] When fixing the new drum 7, the operator places the positioning cylinders 11 at both ends of the new drum 7 on the two support frames 14. Then, the operator starts the drive motor 16 to run in reverse. When the drive motor 16 runs in reverse, it drives the two threaded sleeves 36 to move towards each other through the two threaded rods 35. When the two threaded sleeves 36 move towards each other, they drive the left moving platform 8 and the right moving platform 9 to move towards each other through the two moving rods 39. At the same time, the two moving rods 39 also drive the two first racks 43 to move towards each other through the connecting rod 42. When the two first racks 43 move towards each other, they drive the two second racks 46 to move away from each other through the two transmission gears 44. When the two second racks 46 move away from each other, they drive the two transmission bars 47 to move away from each other, so that the two transmission bars 47 no longer push the two contact blocks 50. Thus, under the elastic force of the two springs 53, the two rectangular rods 51 are driven to move down. When the two rectangular rods 51 move down, they drive the two support frames 14 away from the two positioning cylinders 11, so as to avoid the two support frames 14 affecting the rotation of the drum 7.

[0040] In Example 3, based on Example 1, the second transmission component includes a worm gear 27, which is fixedly installed at the output end of the servo motor 20. One end of the worm gear 27 is rotatably connected to the inner wall of the protective box 18. A worm wheel 28 is meshed with the surface of the worm gear 27, and a rotating rod 29 is fixedly installed in the middle of the worm wheel 28. First shafts 30 are fixedly installed at both ends of the rotating rod 29. First bushings 31 are rotatably installed on the surfaces of the two first shafts 30. The two first bushings 31 are fixedly connected to both sides of one end of the support frame 17. The ends of the two first shafts 30 that are far apart from each other are fixedly connected to two leveling rollers 2 respectively.

[0041] When the ground soil is uneven, the operator activates the hydraulic cylinder 22 to move the connecting frame 26 downward. The connecting frame 26, through the cooperation of the pin 25 and the hollow strip 24, drives the support frame 17 to rotate downward, thereby moving the two leveling rollers 2 to the ground. At the same time, the operator activates the servo motor 20 to drive the worm gear 27 to rotate. The worm gear 27 drives the worm wheel 28 to drive the rotating rod 29 to rotate. When the rotating rod 29 rotates, it drives the two first shafts 30 to rotate along the inside of the two first bushings 31. When the two first shafts 30 rotate, they drive the two leveling rollers 2 to rotate.
