Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] Please refer to the following: Figures 1 to 4 To achieve the above objectives, this utility model provides the following technical solution: A shore power winch cable conductor mechanism includes a base 1 and a support frame 2 disposed above the base 1, and further includes: The take-up and unwind roller 3 is set above the support frame 2. The roller shafts 4 at both ends of the take-up and unwind roller 3 are rotatably connected to the support frame 2 through bearing seats 5, and are used to wind the cable. Servo motor 6 is located at one end of take-up and untake-up roller 3. The output shaft of servo motor 5 is fixedly connected to roller shaft 4 of take-up and untake-up roller 3 through a coupling. It is used to drive take-up and untake-up roller 3 to rotate. The cable conductor mechanism 7 is disposed above the base 1, wherein the cable conductor mechanism 7 is used to guide the cable so that the cable is evenly laid on the take-up and unwinding roller 3; The wire pressing mechanism 8 is located on the side of the take-up and unwinding roller 3 and is used to press and fix the cable wound on the take-up and unwinding roller 3.

[0020] Servo motor 6 starts working, transmitting rotational power to roller shaft 4 of take-up and undo roller 3 via output shaft and coupling, thereby driving take-up and undo roller 3 to rotate. The roller shafts 4 at both ends of take-up and undo roller 3 are rotatably connected to support frame 2 via bearing seats 5. This connection allows the roller to rotate freely on support frame 2. The bearing seats 5 provide support and reduce friction, ensuring the smoothness and flexibility of roller rotation. During cable take-up and undo, linear screw module 702 drives slide table 703 to reciprocate linearly along its axial direction. Since slide table 703 is fixedly connected to conductor assembly 701, conductor assembly 701 also moves with slide table 703. The cable passes through conductor assembly 701 and is supported by the limiting mechanism of conductor assembly 701. Under the action of the wire assembly 701, the cable can be evenly wound on the take-up and unwinding roller 3, avoiding the problem of messy cable winding. At the same time, the pressing mechanism 8 starts to work, so that the sliding seat 803 drives the pressing roller 805 to approach the take-up and unwinding roller 3 through the support rod 804 and abut against the cable on the outer wall of the take-up and unwinding roller 3. As the cable is continuously wound, the thickness of the cable gradually increases. The pressing roller 805 will drive the sliding seat 803 to move outward a certain distance under the push of the cable, overcoming the tension of the tension spring 806. However, the tension spring 806 always maintains a certain tension, so that the pressing roller 805 always applies pressure to the cable, ensuring that the cable is tightly wound on the take-up and unwinding roller 3, solving the problem of loose cable winding.

[0021] In a preferred embodiment, this utility model can be further configured as follows: Figure 2 As shown; the cable conductor mechanism 7 includes: The conductor assembly 701 is disposed on the side of the base 1 away from the take-up and untake-up roller 3. The conductor assembly 701 is used to limit and support the cable to improve the stability of the cable during the winding process. A linear screw module 702 is located at the lower end of the cable conductor assembly 701. A slide 703 on the linear screw module 702 is fixedly connected to the cable conductor assembly 701 and is used to drive the cable conductor assembly 701 to move. The linear screw module 702 is the power transmission and motion control component of the cable conductor mechanism 7. Its main function is to drive the cable conductor assembly 701 to move synchronously through its own linear motion. During cable winding and unwinding, the linear screw module 702 can reciprocate linearly along a direction parallel to the axial direction of the winding and unwinding roller 3. The movement causes the wire assembly 701 to move as well; the linear screw module 702 drives the wire assembly 701 to move, and after the cable passes through the wire assembly 701, it can be evenly laid out on the take-up and unwinding roller 3. When the linear screw module 702 moves in one direction, the cable will start to wind on one side of the take-up and unwinding roller 3; when the linear screw module 702 moves in the opposite direction, the cable will wind on the other side of the take-up and unwinding roller 3. This process is repeated to make the cable evenly distributed in the width direction of the entire take-up and unwinding roller 3.

[0022] During the cable winding and unwinding process, the cable is first passed through the conductor assembly 701, which is initially positioned at one end of the linear screw module 702. At this point, the cable begins to wind around one side of the take-up and unwinding roller 3. Then, the servo motor 6 is activated to drive the take-up and unwinding roller 3 to rotate. Simultaneously, the drive device of the linear screw module 702 is activated, driving the conductor assembly 701 to move according to a preset direction and speed. As the conductor assembly 701 moves, the cable, under the limiting support of the conductor assembly 701, is evenly wound onto the take-up and unwinding roller 3 along a path consistent with the moving direction of the conductor assembly 701. When the conductor assembly 701 moves to the linear screw module 702... At the other end of the lead screw module 702, the drive device of the linear lead screw module 702 rotates in the opposite direction, driving the conductor assembly 701 to move in the opposite direction, and the cable is wound on the other side of the take-up and unwinding roller 3; the linear lead screw module 702 continuously repeats the above reciprocating motion, and the conductor assembly 701 also moves continuously, so that the cable always maintains a uniform wire arrangement during the entire take-up and unwinding process until the cable take-up and unwinding are completed; through the coordinated work of the conductor assembly 701 and the linear lead screw module 702, the cable conductor mechanism 7 can effectively solve the problems of messy cable winding and loose coiling in the prior art, and improve the efficiency and quality of shore power winch cable take-up and unwinding.

[0023] In a preferred embodiment, this utility model can be further configured as follows: Figure 1As shown in the figure; the moving direction of the linear screw module 702 is arranged parallel to the axial direction of the wire winding and unwinding roller 3. The linear screw module 702 drives the wire guiding component 701 to reciprocate along the axial direction of the wire winding and unwinding roller 3, so that the cable is evenly wound on the wire winding and unwinding roller 3. By setting the moving direction of the linear screw module 702 to be parallel to the axial direction of the wire winding and unwinding roller 3, and using the linear screw module 702 to drive the wire guiding component 701 to reciprocate along the axial direction of the wire winding and unwinding roller 3, the cable is distributed according to a specific law during the winding and unwinding process, avoiding problems such as cable accumulation in one place or loose and uneven winding, thereby improving the efficiency and quality of cable winding and unwinding and ensuring the stable operation of the onshore power supply system.

[0024] In a preferred embodiment of the present invention, it can be further configured as follows: As Figure 3 shown; the wire guiding component 701 includes: a "C"-shaped support frame 7011, the lower end of which is fixedly connected to the slide table 703; a left-right hand screw 7012, arranged in the inner cavity of the "C"-shaped support frame 7011, and its two ends are respectively rotatably connected to the "C"-shaped support frame 7011; two clamping plates 7013, symmetrically arranged at both ends of the left-right hand screw 7012, and they are threadedly connected to the left-right hand screw 7012 through screw nuts 7014; a limiting cam 7015, arranged at the clamping end of the clamping plate 7013, and it is rotatably connected to the clamping plate 7013 for guiding and supporting the cable; A drive motor 7016 is mounted at the top of a U-shaped support frame 7011. The output end of the drive motor 7016 is fixedly connected to a positive and negative threaded rod 7012 via a coupling. When the drive motor 7016 drives the positive and negative threaded rod 7012 to rotate, because the positive and negative threaded rod 7012 has threads in two different directions, the two screw nuts 7014, which are screwed to the positive and negative threaded rod 7012, will move linearly in opposite directions along the screw axis. By controlling the rotation of the positive and negative threaded rod 7012, the distance between the two clamping plates 7013 can be precisely adjusted to accommodate cables of different diameters, achieving effective clamping and guidance of the cables. The limiting concave wheel 7015 can move with the cable... The clamping plate 7015 rotates freely during movement, while simultaneously guiding and supporting the cable. The limiting concave wheel 7015 ensures the cable remains stable during movement, preventing swaying, twisting, or deviation from the track, thus guaranteeing smooth and accurate cable winding and unwinding. Two clamping plates 7013 move closer or further apart under the drive of the positive and negative threaded rods 7012, adjusting the clamping force and range on the cable. When the clamping plates 7013 approach each other, the limiting concave wheel 7015 tightly adheres to the cable surface, restricting lateral movement and ensuring the cable moves along a predetermined path during winding and unwinding. When changing to a cable of a different diameter, the clamping plates 7013 can move apart to facilitate easy insertion or removal of the cable.

[0025] In a preferred embodiment, this utility model can be further configured as follows: Figure 3 As shown, the limiting concave wheels 7015 mounted on the two clamping plates 7013 are arranged opposite each other so that the grooves of the limiting concave wheels 7015 limit the cable. The rotation of the positive and negative threaded rods 7012 is controlled by the drive motor 7016, so that the two clamping plates 7013 drive the limiting concave wheels 7015 to generate a certain clamping force on the cable. When the two limiting concave wheels 7015 are arranged opposite each other, the two grooves together form a space similar to a channel or clamp, so that the cable is stably placed in the space defined by the two grooves, thereby limiting the cable. After the cable is confined in the space formed by the two grooves, the contour of the grooves fits (or nearly fits) the outer surface of the cable, which constrains the cable in the lateral direction (perpendicular to the cable axis), preventing the cable from deviating or shaking significantly in this direction, further enhancing the limiting effect on the cable, and ensuring that the cable remains stable in the required position.

[0026] In a preferred embodiment, this utility model can be further configured as follows: Figure 3As shown, guide rods 7017 are arranged side by side on one side of the positive and negative threaded rods 7012. The guide rods 7017 pass through the clamping plate 7013 and are slidably connected to it. The guide rods 7017 play a role in restricting the movement direction of the clamping plate 7013 during the entire movement. Because the clamping plate 7013 and the guide rods 7017 are slidably connected, the clamping plate 7013 can only move linearly along the axis of the guide rods 7017, and cannot deviate or rotate in the direction perpendicular to the guide rods 7017. This ensures that the clamping plate 7013 can maintain a stable movement trajectory when it moves with the rotation of the positive and negative threaded rods 7012, which improves the clamping accuracy and reliability and avoids the problem of unstable clamping or damage to the clamped object caused by the wobbling of the clamping plate 7013.

[0027] In a preferred embodiment, this utility model can be further configured as follows: Figure 4 As shown; the pressing mechanism 8 includes a limiting guide rod 801, wherein the limiting guide rod 801 has fixed seats 802 at both ends, and the fixed seats 802 are mounted on and fixedly connected to the support frame 2 on one side of the take-up and unload roller 3; a sliding seat 803 is slidably connected to the limiting guide rod 801, wherein the sliding seat 803 has a support rod 804 on the side near the take-up and unload roller 3; the support rod 804 is movably and fixedly connected to the sliding seat 803, wherein the other end of the support rod 804 is provided with a pressing roller 805; the pressing roller 805 abuts against the outer wall of the take-up and unload roller 3 so that the pressing roller 805 presses the cable wound on the take-up and unload roller 3; since the sliding seat 803 is slidably connected to the limiting guide rod 801, the sliding seat 803 can only move linearly along the axis of the limiting guide rod 801, and cannot deviate or rotate in other directions, which ensures the support rod 804 fixedly connected to the sliding seat 803 and the pressing roller mounted on the support rod 804. Roller 805 can also move stably along the direction determined by guide rod 801, thereby ensuring that pressure roller 805 can accurately act on the cable on take-up and undo roller 3. By adjusting the position of sliding seat 803 on guide rod 801, the distance between pressure roller 805 and take-up and undo roller 3 can be changed, thereby adjusting the clamping force of pressure roller 805 on cable. When sliding seat 803 moves closer to take-up and undo roller 3, support rod 804 drives pressure roller 805 closer to cable, increasing the pressure between pressure roller 805 and cable, thereby subjecting cable to greater clamping force and enabling it to be wound more tightly on take-up and undo roller 3. Conversely, when sliding seat 803 moves away from take-up and undo roller 3, the clamping force of pressure roller 805 on cable decreases. During take-up and undo, this adjustable clamping force can adapt to the requirements of different cable specifications and different take-up and undo speeds, ensuring the winding quality of cable.

[0028] In a preferred embodiment, this utility model can be further configured as follows: Figure 4As shown; a tension spring 806 is provided on one side of the sliding seat 803, wherein one end of the tension spring 806 is connected to the sliding seat 803, and the other end of the tension spring 806 is connected to the fixed seat 802; when the pressing mechanism 8 is not working, the tension spring 806 is in a certain initial tension state. At this time, the spring will generate a pulling force towards the fixed seat 802. This pulling force is transmitted through the sliding seat 803 to the support rod 804 and the pressing roller 805, so that the pressing roller 805 generates an initial pressing force on the cable on the take-up and unwinding roller 3, ensuring that the cable can be initially pressed when take-up and unwinding begin, avoiding the cable from becoming loose or scattered on the take-up and unwinding roller 3; during the take-up and unwinding process, as the take-up and unwinding roller 3 rotates, the winding diameter of the cable on the take-up and unwinding roller 3... The working principle changes as follows: When the cable winding diameter increases, the cable pushes the pressure roller 805 outward, and the sliding seat 803 slides outward along the limit guide rod 801. At this time, the tension spring 806 is further stretched, and the spring force increases. The clamping force transmitted to the pressure roller 805 through the sliding seat 803 also increases accordingly, thus adapting to the greater clamping force required after the cable winding diameter increases, ensuring that the cable is always tightly wound on the take-up and unwinding roller 3. Conversely, when the cable winding diameter decreases, the tension of the tension spring 806 pulls the sliding seat 803 inward, causing the pressure roller 805 to move closer to the take-up and unwinding roller 3, so that the clamping force of the pressure roller 805 on the cable is appropriately reduced, avoiding damage to the cable or affecting the smoothness of take-up and unwinding due to excessive clamping force.
