Technical Field
[0001] This invention relates to the field of cable reeling vehicle technology, and more particularly to a cable reeling vehicle cable-assisted guiding mechanism and a cable reeling vehicle. Background Technology
[0002] Traditional cable winding vehicles present numerous problems in cable winding operations. During unwinding, the cable easily becomes loose on the winding rollers, leading to uneven transport and impacting efficiency and quality. Furthermore, inspecting the cable's outer wall is inconvenient, making it difficult to detect minor damage such as scratches and cracks, posing safety hazards for subsequent use. Moreover, when the cable has sections where its diameter has increased due to vulcanization, transport becomes difficult, easily causing jams. In addition, there is a lack of effective on-site repair methods for detected cable outer wall damage, requiring additional equipment and procedures, increasing operating costs and time. Summary of the Invention
[0003] The purpose of this invention is to address the shortcomings of existing cable unwinding methods, such as easy loosening, inconvenience in outer wall inspection, and difficulty in damage repair. The invention proposes a cable rewinding cart with cable-assisted guidance mechanism and a cable rewinding cart, which is suitable for cable rewinding operations in large equipment such as high-voltage power stations and electric shovels in the field. It can effectively solve the cable operation problems under complex working conditions.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A cable reel cart cable-assisted guiding mechanism includes a cable winding mechanism, wherein two cable winding mechanisms are respectively electrically connected to a high-voltage power station and an electric shovel;
[0006] The cable winding mechanism includes a winding roller and a main frame, and also includes a drive structure, which includes a reciprocating screw and two sliding guide rods.
[0007] It also includes a conveying structure for preventing the cable from loosening when the cable is unwound by the unwinding roller. The conveying structure includes multiple strip grooves I disposed on both sides of the main frame.
[0008] Side frame bodies are fixedly installed at both ends of the main frame body. A guide frame body is rotatably connected to one side of the side frame body located at the end of the main frame body away from the winding and unwinding roller. A fixing ring is fixedly connected to one side of the side frame body located at the end of the main frame body closer to the winding and unwinding roller.
[0009] The fixing ring is equipped with multiple industrial cameras on the side near the winding roller for detecting the outer wall of the cable. The fixing ring is equipped with a repair structure, which includes a winding roller and insulating tape wound around the outer wall of the winding roller.
[0010] In one possible design, the drive structure further includes a movable support with a slider fixed inside. The movable support slides with the helical groove on the outer wall of the reciprocating screw via the slider. The movable support is fixed to the bottom of the main frame and is used to drive the main frame to move back and forth. Two sets of guide structures are arranged vertically on both sides of the movable support. Two adjacent guide structures are set at the top and bottom of the corresponding sliding guide rod. The guide structure consists of two rolling wheels I rotating on one side of the movable support. The rolling wheels I enable the movable support to move smoothly on the sliding guide rod.
[0011] In one possible design, the conveying structure further includes multiple fixed shafts I, arranged obliquely from left to right and slidably disposed within corresponding strip grooves I; each of the multiple fixed shafts I has two vertical rods slidably passing through it, the vertical rods being fixedly connected to the main frame body, and springs being fitted onto the outer walls of the vertical rods, the bottom ends of the springs being fixedly connected to the top of the fixed shafts I via spring seats, and the top ends being fixedly connected to the main frame body via spring seats; pressure rollers I are rotatably fitted onto the outer walls of the two fixed shafts I at both ends, and the multiple fixed shafts I in the middle... A pressure roller II is rotatably sleeved on the outer wall of the fixed shaft I. The pressure roller I and pressure roller II press the cable through the elastic force of the spring. A drive shaft I is rotatably connected inside the main frame. The main frame contains a drive shaft II. Two sprockets are respectively fixedly sleeved on the outer wall of drive shaft I and rotatably sleeved on the outer wall of drive shaft II. The two sprockets are connected by chain drive. A rubber conveying block is fixed on each link of the chain. The cable is laid on the rubber conveying block. The pressure roller I and pressure roller II press the cable tightly against the rubber conveying block, thereby evenly conveying the cable during unwinding.
[0012] In one possible design, the top and bottom of the side frame are provided with clearance grooves, and the same moving shaft slides in two adjacent clearance grooves; a crossbeam is fixed inside the side frame, and the crossbeam slides through the moving shaft; a bidirectional lead screw rotates inside the side frame, and two moving shafts are threaded to the bidirectional lead screw through internal threads, and are respectively located in the positive and negative thread sections of the bidirectional lead screw, and the rotation of the bidirectional lead screw drives the two moving shafts to move towards each other; rolling wheels II are rotatably sleeved on the outer walls of the two moving shafts for guiding the cables.
[0013] In one possible design, the main frame has strip grooves II on both sides, and the two ends of the drive shaft II slide through the strip grooves II; bolts are fixed to both sides of the main frame by upright plates, the bolts pass through the drive shaft II, and the position of the drive shaft II is controlled by adjusting the threaded engagement of the adjusting nut, thereby adjusting the tension of the chain.
[0014] In one possible design, two guide wheels I are rotatably connected inside the guide frame body, and a guide wheel II is rotatably connected to one side of the side frame body located at the end of the main frame body away from the winding and unwinding roller. The guide wheel II is located above the two guide wheels I, and the cable is guided by the cooperation of the guide wheel II and the guide wheel I.
[0015] In one possible design, the repair structure further includes an electric push rod I, which is fixed to the side of the fixing ring near the unwinding roller. Its output shaft is slidably connected to a lifting plate via a slider and a groove. A mechanical claw is fixed to the top of the lifting plate for gripping one end of the insulating tape. A connecting plate is fixed to one side of the fixing ring, and a track groove is provided in the connecting plate. A pin that slides with the track groove is fixed to one side of the lifting plate. An electric push rod II is fixed inside the fixing ring, and its output shaft is rotatably connected to a rotating rod via a damping bearing. An arc-shaped pressure plate is fixed to one end of the rotating rod for pressing the insulating tape onto the outer wall of the cable. A spur gear ring II is slidably sleeved on the outer wall of the rotating rod. A housing is fixed to one side of the connecting plate, and the spur gear ring II is rotatably disposed within the housing. A lifting frame is slidably connected to the side of the connecting plate away from the lifting plate. A moving groove is provided on one side of the lifting frame. One end of the pin slides into the moving groove, so that the lifting plate and the lifting frame rise and fall synchronously. A spur rack is fixed to one end of the lifting frame. The spur rack meshes with the spur gear ring II. When the lifting frame moves down, it drives the rotating rod and the arc-shaped pressure plate to rotate, so as to rotate the arc-shaped pressure plate out of the fixed ring. The repair structure can meet the needs of rapid repair in field operations and reduce the overall operating cost.
[0016] In one possible design, a rotating ring is slidably connected inside the fixed ring, and a spur gear I is fixedly sleeved on the outer wall of the rotating ring. A gear is rotatably connected to the top of the fixed ring via a base, and the gear meshes with the spur gear I to drive the rotating ring to rotate. The take-up roller is rotatably mounted on the inner wall of the rotating ring via the base, and the rotation of the rotating ring drives the insulating tape to wind around the cable.
[0017] In one possible design, the side of the fixing ring closest to the winding roller is slidably connected to multiple sliding platforms via an arc-shaped slide rail. Multiple industrial cameras are respectively fixed to one side of their respective sliding platforms, and the sliding platforms are fixedly connected to each other via arc-shaped rods. The side of the connecting plate furthest from the fixing ring is rotatably connected to a drive shaft III via a base. A rubber wheel is fixedly fitted onto the outer wall of the drive shaft III, contacting the outer wall of the cable and rotating due to friction. A cam is fixed to one end of the drive shaft III, and a trapezoidal plate is positioned above the cam. The trapezoidal plate is fixedly connected to an adjacent sliding platform, and the cam's rotation intermittently pushes the sliding platform to slide, allowing the industrial cameras to detect the outer wall of the cable. A tension spring is fixed to one side of the connecting plate via a spring seat, and the tension spring is connected to the sliding platform for resetting.
[0018] This invention drives the camera to move by transmitting power through the cable itself, eliminating the need for an additional motor, reducing the energy consumption and size of the equipment, and achieving precise synchronization between the detection action and the cable transmission, avoiding timing errors caused by independent driving.
[0019] A cable reeling vehicle includes the cable reeling vehicle cable assist guide mechanism described above, and also includes a tracked vehicle. The reeling roller is rotatably mounted on the top of the tracked vehicle via a base, the reciprocating screw is rotatably mounted on the top of the tracked vehicle via a base, and the two sliding guide rods are fixed to the top of the tracked vehicle via a base.
[0020] Beneficial effects: In this invention, multiple sliding platforms are fixedly connected by arc-shaped rods. A drive shaft III is rotatably connected to the side of the connecting plate away from the fixed ring. A cam is fixed to one end of the drive shaft III. A matching trapezoidal plate is provided above the cam. The trapezoidal plate is fixedly connected to the adjacent sliding platform. The cable is laid on the rubber wheel. As the cable is transported, the friction between the cable and the rubber wheel drives the drive shaft III and the rubber wheel to rotate. During the rotation, the cam cooperates with the trapezoidal plate to intermittently push the sliding platform and the industrial camera to slide, thereby enabling multiple industrial cameras to observe the outer wall of the cable and check for minor damage such as scratches and cracks on the outer wall of the cable.
[0021] In this invention, a lifting plate slides on the top of the output shaft of the electric push rod I, a track groove is provided in the connecting plate, and a pin is fixed on one side of the lifting plate that slides with the track groove. One end of the output shaft of the electric push rod II is rotatably connected to a rotating rod through a damping bearing. A straight toothed ring II is slidably sleeved on the outer wall of the rotating rod. A lifting frame is slidably connected to one side of the connecting plate, and a straight toothed rack is fixed at one end of the lifting frame. The mechanical claw grabs one end of the insulating tape and pulls the insulating tape downward. The electric push rod II presses the insulating tape onto the cable to be repaired position through an arc-shaped pressure plate. The insulating tape drives the lifting plate to move downward, which can move the lifting plate and the mechanical claw outward, avoiding the lifting plate from affecting the insulating tape wrapping around the cable outer wall later. The straight toothed rack meshes with the straight toothed ring II and drives the arc-shaped pressure plate to rotate. Therefore, after the arc-shaped pressure plate releases the pressure on the insulating tape, the arc-shaped pressure plate rotates out of the fixed ring, also avoiding affecting the subsequent wrapping of the insulating tape.
[0022] In this invention, the vertical rods are slidably disposed within two corresponding strip grooves I, and two vertical rods slide through the fixed shaft I. Springs are fitted onto the outer walls of each of the vertical rods. The drive shaft I drives the rubber conveying block through the cooperation of a sprocket and a chain. At this time, the cable rests on the rubber conveying block, and the two pressure rollers I and multiple pressure rollers II press the cable under the elastic force of the springs, ensuring the cable is tightly pressed against the rubber conveying block. Therefore, when unwinding the cable from the winding rollers, the cable can be conveyed evenly, preventing the cable from becoming loose on the winding rollers during unwinding. Furthermore, the cooperation of the springs and the fixed shaft I causes the pressure rollers I and II to press the cable, and the rotation of the bidirectional screw can adjust the distance between the two rolling rollers II. This allows for the smooth conveying of even sections of the cable whose diameter has increased due to vulcanization.
[0023] In this invention, the conveying, detection, and repair structures form a closed-loop synergy. Conveying provides a stable foundation for detection, detection provides accurate information for repair, and repair promptly resolves on-site problems, thereby improving the overall safety and efficiency of cable winding operations and meeting the stringent requirements of field mobile operations.
[0024] In this invention, regarding cable conveying, the conveying structure ensures uniform unwinding, preventing cable loosening on the unwinding rollers, reducing cable friction and collisions, protecting the cable sheath, extending cable lifespan, and adapting to cables of different diameters, including areas with increased vulcanization diameter, ensuring smooth conveying. For inspection, multiple industrial cameras slide along the drive shaft III and rubber wheels, providing comprehensive observation of the cable's outer wall and timely detection of scratches, cracks, and other damage. In the repair process, electric push rods I and II work together, a mechanical claw grips the insulating tape, and an arc-shaped pressure plate presses it for repair. During repair, the lifting plate and mechanical claw automatically adjust their positions, and the arc-shaped pressure plate rotates out after repair without affecting subsequent winding, achieving efficient on-site repair and reducing operating costs and time.

[0043] 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.
[0044] In one embodiment: Refer to Figures 1-14 A cable reeling and unwinding vehicle with a cable-assisted guiding mechanism includes a tracked vehicle 1, a cable reeling mechanism, a drive structure, a conveying structure, a guiding structure, and a repair structure. The tracked vehicle 1 serves as the platform for the entire mechanism, providing the mounting base for other components. The cable reeling mechanism is used to wind and unwind the cable and makes electrical connections to high-voltage substations and electric shovels. The drive structure drives the main frame 3 to reciprocate, ensuring that the cable conveyed by the main frame 3 aligns with the cable exit position on the reeling roller 2. The conveying structure prevents the cable from becoming loose on the reeling roller 2 during unwinding. The guiding structure guides the cable, ensuring it is conveyed along a predetermined path. The repair structure detects and repairs scratches and cracks on the cable's outer wall.
[0045] Reference Figure 1The tracked vehicle 1, serving as the mobile carrier for the cable-assisted guiding mechanism of the entire cable reeling vehicle, possesses good off-road performance and stability, enabling it to navigate various complex terrain conditions. The top of the tracked vehicle 1 provides a flat and robust platform for the installation of other components; its dimensions and load-bearing capacity are designed according to actual requirements. The load-bearing capacity of the tracked vehicle 1 should be sufficient to support the weight of components such as the cable reeling mechanism, drive structure, and conveying structure, as well as the weight of the cable itself, typically between 5 and 10 tons.
[0046] Reference Figure 1 and Figure 2 The cable winding mechanism includes a winding roller 2 and a main frame 3. The winding roller 2 is rotatably mounted on top of the tracked vehicle 1 via a base, and its diameter and length are designed according to the cable specifications and length. The surface of the winding roller 2 is smoothed to reduce friction during cable winding and unwinding, preventing damage to the cable sheath. The main frame 3 is mounted on the tracked vehicle 1 and is used to support and secure other related components. The main frame 3 is made of high-strength steel, possessing good rigidity and stability, and can withstand various forces generated during cable transportation.
[0047] Reference Figures 1-4 The drive structure includes a reciprocating screw 5, a sliding guide rod 6, and a movable support 4. The reciprocating screw 5 is rotatably mounted on the top of the tracked vehicle 1 via a base, and its length matches the travel of the main frame 3. The sliding guide rod 6 is fixedly mounted on the top of the tracked vehicle 1 via a base, and the two sliding guide rods 6 are arranged in parallel and parallel to each other with the reciprocating screw 5. The surface is smoothed to reduce friction on the movable support 4 during movement. A slider is fixed inside the movable support 4, and the slider slides into the helical groove on the outer wall of the reciprocating screw 5. The movable support 4 is fixed to the bottom of the main frame 3. When the reciprocating screw 5 rotates, the slider and the helical groove drive the movable support 4 and the main frame 3 to move reciprocally. Two sets of guide structures are arranged vertically on both sides of the movable support 4. Each set of guide structures consists of two rolling wheels I7 rotating on one side of the movable support 4. Two adjacent guide structures are set at the top and bottom of the corresponding sliding guide rods 6 to make the movable support 4 move smoothly on the sliding guide rods 6. The material is wear-resistant rubber to reduce friction and wear with the sliding guide rod 6.
[0048] Reference Figures 4-6The conveying structure includes multiple strip grooves I12 arranged on both sides of the main frame 3, fixed shafts I13, vertical rods 14, springs 15, pressure rollers I16 and II17, drive shafts I18 and II19, sprockets 20, chains 21, and rubber conveying blocks 22. The multiple strip grooves I12 are arranged obliquely from left to right on both sides of the main frame 3. Multiple fixed shafts I13 are slidably disposed within corresponding two strip grooves I12, and are arranged obliquely from left to right. Two vertical rods 14 slide through each of the multiple fixed shafts I13, and all vertical rods 14 are fixedly connected to the main frame 3. Springs 15 are fitted onto the outer walls of each of the multiple vertical rods 14. The bottom end of each spring 15 is fixedly connected to the top of the corresponding fixed shaft I13 via a spring 15 seat, and the top end of each spring 15 is fixedly connected to the main frame 3 via a spring 15 seat. Spring 15 is made of carbon steel wire with an elastic modulus between 50-100 N / mm. The initial compression is designed according to the actual required elastic force, generally 10-20 mm. The elastic force of spring 15 enables pressure rollers I 16 and II 17 to press the cable and make way for positions with different diameters on the cable.
[0049] Reference Figure 6 Pressure rollers I16 are rotatably fitted onto the outer walls of the two fixed shafts I13 at both ends, and pressure rollers II17 are rotatably fitted onto the outer walls of the multiple fixed shafts I13 in the middle. The material is wear-resistant rubber to increase friction with the cable and reduce damage to the cable.
[0050] Reference Figures 5-7 The main frame 3 is rotatably connected to a drive shaft I 18 and a drive shaft II 19. It also includes two sprockets 20, one fixedly mounted on the outer wall of drive shaft I 18, and the other rotatably mounted on the outer wall of drive shaft II 19. The two sprockets 20 are connected by a chain 21, which is located below pressure rollers I 16 and II 17. The chain 21 is a standard roller chain with a pitch of 15-20 mm, and the appropriate number of links is selected according to the length of the main frame 3 and the conveying requirements. Each link of the chain 21 is fixed with a rubber conveying block 22. The top of the rubber conveying block 22 has an arc-shaped groove to increase the contact area between the rubber conveying block 22 and the cable. The rubber conveying block 22 is made of natural rubber with a hardness between 50-70 Shore A, and its dimensions are 30-50 mm long, 20-30 mm wide, and 10-15 mm high.
[0051] The drive shaft I18 is rotated by a motor, and the drive shaft I18 drives the rubber conveyor block 22 through the cooperation of the sprocket 20 and the chain 21. At this time, the cable is placed on the rubber conveyor block 22, and the two pressure rollers I16 and multiple pressure rollers II17 are pressed against the cable by the elastic force of the spring 15, making the cable tightly adhere to the rubber conveyor block 22. Therefore, when the cable is unwound by the unwinding roller 2, the cable can be conveyed evenly, and the cable cannot become loose on the unwinding roller 2 during the unwinding process. In addition, the pressure rollers I16 and II17 are pressed against the cable by the cooperation of the spring 15 and the fixed shaft I13, which can convey cables of different diameters.
[0052] Reference Figure 4 , Figure 5 and Figure 8 The side frame 8 is fixedly installed at both ends of the main frame 3 to guide the cable. The top and bottom of the side frame 8 each have two clearance grooves, with the same moving shaft 27 sliding within adjacent grooves. A crossbeam 26 is fixed near the bottom of the side frame 8, with one end of the crossbeam 26 sliding through both moving shafts 27. A bidirectional lead screw 29 rotates near the top of the side frame 8. Both moving shafts 27 have internal threads and are threadedly connected to the bidirectional lead screw 29, with each shaft located on a different threaded section of the lead screw 29. Rotating the bidirectional lead screw 29 drives the two moving shafts 27 to move towards each other. Roller rollers Ⅱ28 are rotatably fitted onto the outer walls of both moving shafts 27 to guide the transported cable. The rollers are made of wear-resistant rubber.
[0053] Reference Figure 4 , Figure 7 and Figure 17 Both sides of the main frame 3 are provided with strip grooves II 25. The two ends of the drive shaft II 19 pass through the corresponding strip grooves II 25 and are slidably connected to them. Both sides of the main frame 3 are fixed with bolts 23 by upright plates. The ends of the two bolts 23 near the drive shaft I 18 pass through the drive shaft II 19, and the outer walls of the two bolts 23 are threaded with adjusting nuts 24. The position of the drive shaft II 19 can be controlled by the cooperation of the bolts 23 and the adjusting nuts 24, which facilitates the control of the tension of the chain 21 and the subsequent disassembly of the chain 21.
[0054] Reference Figure 4 and Figure 8A guide frame 9 is rotatably connected to one side of the side frame 8 located at the end of the main frame 3 away from the winding roller 2. Two guide wheels I 10 are rotatably connected inside the guide frame 9. A guide wheel II 11 is also rotatably connected to one side of the side frame 8 located at the end of the main frame 3 away from the winding roller 2. Guide wheel II 11 is located on the side of the corresponding moving shaft 27 away from the main frame 3, and is positioned above the two guide wheels I 10. During cable transport, the cooperation between guide wheel II 11 and the two guide wheels I 10 guides the cable, ensuring it is transported along a predetermined path.

The insulating tape 34 is made of polyvinyl chloride, with a thickness of 0.1-0.2 mm and a width of 20-30 mm.
[0057] Reference Figure 2 and Figure 9 Multiple industrial cameras 50 are installed on the side of the retaining ring 30 near the winding roller 2 for inspecting the outer wall of the cable. The industrial cameras 50 are high-definition cameras with a resolution of 1080P or higher, capable of clearly capturing images of the outer wall of the cable.

One end of the output shaft of the electric push rod II 42 is rotatably connected to a rotating rod 43 via a damping bearing. An arc-shaped pressure plate 44 is fixed to one end of the rotating rod 43, which is used to press the insulating tape 34 onto the outer wall of the cable. The arc of the arc-shaped pressure plate 44 matches the outer diameter of the cable and is made of rubber to increase the friction with the insulating tape 34. A serrated plate 58 is fixed to the top of the arc-shaped pressure plate 44, which is used to cut the insulating tape 34 after it has been wrapped.

A housing 45 is fixed to one side of the connecting plate 36, and the spur gear ring II 46 rotates within the housing 45. A lifting frame 48 is slidably connected to the side of the connecting plate 36 away from the lifting plate 38. A moving groove 49 is provided on one side of the lifting frame 48, and one end of the pin 41 extends into the moving groove 49 and slides into it, for synchronously raising and lowering the lifting plate 38 and the lifting frame 48. A spur gear 47 is fixed to one end of the lifting frame 48, and the spur gear 47 passes through the housing 45 and meshes with the spur gear ring II 46, for driving the rotating rod 43 and the arc-shaped pressure plate 44 to rotate when the lifting frame 48 moves downward, thereby rotating the arc-shaped pressure plate 44 out of the fixed ring 30 to avoid affecting the subsequent winding of the insulating tape 34.
[0061] The output shaft of electric actuator I 37 pushes the lifting plate 38 and mechanical claw 39 upwards. The mechanical claw 39 grasps one end of the insulating tape 34 and pulls the insulating tape 34 downwards until the end of the insulating tape 34 is below the arc-shaped pressure plate 44. Then, the output shaft of electric actuator II 42 pushes the rotating rod 43 and the arc-shaped pressure plate 44 to move, pressing the insulating tape 34 onto the cable to be repaired and making the insulating tape 34 adhere to the outer wall of the cable. Electric actuator I 37 drives the lifting plate 38 and mechanical claw 39 downwards. The pin 41 extends from the vertical slot to the inclined slot and moves, which can move the lifting plate 38 and mechanical claw 39 outwards to prevent the lifting plate 38 from affecting the insulating tape 34 from wrapping around the outer wall of the cable later. Furthermore, when the lifting plate 38 moves down, the straight rack 47 moves down synchronously through the cooperation of the pin 41 and the lifting frame 48. The straight rack 47 meshes with the straight rack ring II 46 and drives the arc-shaped pressure plate 44 to rotate. Therefore, after the arc-shaped pressure plate 44 releases its pressure on the insulating tape 34, the arc-shaped pressure plate 44 turns its direction and rotates out of the fixed ring 30, thus avoiding affecting the subsequent winding of the insulating tape 34.
[0062] Reference Figure 10 and Figure 14A rotating ring 31 is slidably connected inside a fixed ring 30. A spur gear ring I 32 is fixedly sleeved on the outer wall of the rotating ring 31. A gear 33 is rotatably connected to the top of the fixed ring 30 via a base, and the gear 33 meshes with the spur gear ring I 32 to drive the rotating ring 31 to rotate. A take-up roller 35 rotates on the inner wall of the rotating ring 31 via a base. The gear 33 is driven to rotate by a motor, and the meshing of the gear 33 with the spur gear ring I 32 drives the rotating ring 31 to rotate. In turn, the insulating tape 34 can be wound around the outer wall of the cable by cooperating with the take-up roller 35.
[0063] A cable reeling vehicle includes the cable-assisted guiding mechanism described above.
[0064] In another embodiment: Refer to Figure 15 and Figure 16 A fixed ring 30 is slidably connected to multiple sliding platforms 51 via an arc-shaped slide rail on the side near the winding roller 2. Multiple industrial cameras 50 are respectively fixed to one side of their respective sliding platforms 51. The multiple sliding platforms 51 are fixedly connected to each other via an arc-shaped rod 52, enabling synchronous movement. A drive shaft Ⅲ 53 is rotatably connected to the side of the connecting plate 36 away from the fixed ring 30 via a base. A rubber wheel 54 is fixedly fitted onto the outer wall of the drive shaft Ⅲ 53, and the rubber wheel 54 contacts the outer wall of the cable, driving the cable to rotate through friction. The material is natural rubber with a hardness between 60-80 Shore A.
[0065] Reference Figure 16 A cam 55 is fixed to one end of the drive shaft Ⅲ 53. A trapezoidal plate 56 is provided above the cam 55, and the trapezoidal plate 56 is fixedly connected to the adjacent sliding platform 51. When the cam 55 rotates, the trapezoidal plate 56 pushes the sliding platform 51 to slide along the arc-shaped slide rail. A tension spring 57 is fixed to one side of the connecting plate 36 near the bottom via a spring seat. The end of the tension spring 57 away from the connecting plate 36 is fixedly connected to the adjacent sliding platform 51 via a spring seat, which is used to reset the sliding platform 51 and the arc-shaped rod 52. The tension spring 57 is made of carbon spring 15 steel wire, and its elastic coefficient is between 30-60 N / mm. The initial tension is designed according to the actual required tension, generally 10-15 mm.
[0066] The cable is laid on the rubber wheel 54. As the cable is transported, the friction between the cable and the rubber wheel 54 drives the drive shaft Ⅲ 53 and the rubber wheel 54 to rotate. During the rotation, the cam 55 cooperates with the trapezoidal plate 56 to intermittently push the sliding platform 51 and the industrial camera 50 to slide, so that multiple industrial cameras 50 can observe the outer wall of the cable and check for minor damage such as scratches and cracks on the outer wall of the cable.
[0067] A method for using a cable-assisted guiding mechanism for a cable reel cart includes the following steps:
[0068] S1. Tracked vehicle 1 moves to the designated position. The cable in one of the cable winding mechanisms is connected to the high-voltage power station, and the cable in the other winding mechanism is connected to the electric shovel. When the electric shovel moves under the drive of the corresponding equipment, the corresponding cable needs to be unwound. The unwinding roller 2 is driven by the motor to rotate and the cable begins to be unwound. When the electric shovel moves too far and the cable length is insufficient, the tracked vehicle 1 needs to move. At this time, the cable between the tracked vehicle 1 and the high-voltage power station can be unwound, so as to stably supply power to the electric shovel.
[0069] S2. During the unwinding operation of the unwinding roller 2, the drive shaft I18 is driven to rotate by the motor. The drive shaft I18 drives the rubber conveying block 22 to run through the cooperation of the sprocket 20 and the chain 21. At this time, the cable is placed on the rubber conveying block 22, and the two pressure rollers I16 and multiple pressure rollers II17 are pressed against the cable under the elastic force of the spring 15, so that the cable is in close contact with the rubber conveying block 22. Therefore, the cable can be evenly conveyed when the unwinding roller 2 unwinds the cable, and the cable is prevented from becoming loose on the unwinding roller 2 during the unwinding process. In addition, when the pressure rollers I16 and II17 cooperate with the rubber conveying block 22 to convey the cable, the two corresponding rolling rollers II28 set in the two side frame bodies 8 at both ends of the main frame body 3 can guide the cable, and the rotation of the bidirectional screw 29 can control the two rolling rollers II28 to move towards each other to constrain the cable.
[0070] S3. When conveying the cable, the reciprocating screw 5 is driven by the motor to rotate. The reciprocating screw 5 drives the rolling wheel I7 and the main frame 3 to move back and forth along the axis of the sliding guide rod 6. This ensures that the cable exit position on the roller is consistent when unwinding or winding the cable. As the cable on the roller increases or decreases in turn, the cable feeding mechanism can always follow, thus preventing cable twisting and cable tangling.
[0071] S4. In addition, the spring force applied to the fixed shaft I13 by the spring 15 can cause the pressure rollers I16 and II17 to squeeze the cable. Furthermore, high-voltage cables may break or twist during use, rendering them unusable. Therefore, after a cable breaks, it needs to be re-vulcanized. However, the diameter of the joint after vulcanization is larger than that of a conventional cable. Therefore, the distance between the two rolling rollers II28 can be adjusted by rotating the bidirectional screw 29, which allows for the transport of cables of different diameters.
[0072] S5. When the cable enters the main frame 3 from the unwinding roller 2 for subsequent conveying, the cable rests on the rubber wheel 54. As the cable is conveyed, the friction between the cable and the rubber wheel 54 drives the drive shaft Ⅲ 53 and the rubber wheel 54 to rotate. During the rotation, the cam 55 cooperates with the trapezoidal plate 56 to intermittently push the sliding platform 51 and the industrial camera 50 to slide, so that multiple industrial cameras 50 can observe the outer wall of the cable to check for minor damage such as scratches and cracks on the outer wall of the cable. Insulating tape 34 can be used for temporary repairs, and the damaged location can be marked for subsequent professional repair.
[0073] S6. During repair, the output shaft of electric push rod I 37 pushes the lifting plate 38 and mechanical claw 39 upward. The mechanical claw 39 grabs one end of the insulating tape 34 and pulls the insulating tape 34 downward until the end of the insulating tape 34 is below the arc-shaped pressure plate 44. Then, the output shaft of electric push rod II 42 pushes the rotating rod 43 and the arc-shaped pressure plate 44 to move, pressing the insulating tape 34 onto the position of the cable to be repaired and making the insulating tape 34 stick to the outer wall of the cable. Electric push rod I 37 drives the lifting plate 38 and mechanical claw 39 downward, and the pin 41 moves from the vertical slot. Extending to the inclined groove, the lifting plate 38 and mechanical claw 39 can be moved outward to avoid the lifting plate 38 affecting the insulation tape 34 from wrapping around the outer wall of the cable later. When the lifting plate 38 moves down, the straight rack 47 moves down synchronously through the cooperation of the pin 41 and the lifting frame 48. The straight rack 47 meshes with the straight rack ring II 46 and drives the arc-shaped pressure plate 44 to rotate. Therefore, after the arc-shaped pressure plate 44 releases the pressure on the insulation tape 34, the arc-shaped pressure plate 44 turns its direction and rotates out of the fixed ring 30, which also avoids affecting the wrapping of the insulation tape 34 later.
[0074] S7. During the winding process, the motor drives the gear 33 to rotate. The meshing of the gear 33 with the spur ring I 32 drives the rotating ring 31 to rotate. Then, through the cooperation of the insulating tape 34 and the take-up roller 35, the insulating tape 34 can be wound on the outer wall of the cable until the take-up roller 35 moves to the initial position. After the winding is completed, the electric push rod I 37 drives the lifting plate 38 to move upward. At this time, the arc-shaped pressure plate 44 reverses its direction. The output shaft of the electric push rod II 42 pushes the arc-shaped pressure plate 44 to press the outer wall of the cable. Then, the gear 33 drives the rotating ring 31 to rotate in the opposite direction. The insulating tape 34 is attached to the sawtooth plate 58, completing the cutting operation of the insulating tape 34, which is convenient for later winding and repair of other parts of the cable.

They will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.
