Description

Technical Field

[0001] This invention relates to the field of cable winch technology, and more specifically to a cable winch with a slack rope protection structure. Background Technology

[0002] When a ship is docked at the pier, it no longer uses its own generator, but connects to the pier's power supply via cable to obtain power. When the ship leaves the shore, the cable is wound up to prevent it from moving. During this process, the cable is wound up and unwound using a cable winch.

[0003] For example, Chinese patent CN114476866A discloses a shore power cable winch. The winch drives the winding drum to rotate for winding through a drive structure. When the unwinding speed of the winding drum is greater than a preset value, a limiting structure restricts the unwinding rotation of the winding drum to avoid the cable becoming loose and knotted due to the unwinding speed of the winding drum.

[0004] However, when using cables, if they are taut as a whole, they are prone to breakage; if they are too loose, they are prone to friction with other objects, which accelerates wear. Furthermore, during unwinding, the unfolded cable can pull on the cable on the winch, subjecting it to a large continuous tensile force. At the same time, during winding, it is difficult to ensure that the cable is laid tightly and evenly without tautness. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention discloses a cable winch with a slack rope protection structure.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A cable winch with a slack rope protection structure includes a base, a rotating support mechanism, a connecting electrical box and a cable winding and unwinding mechanism, and also includes an anti-slack rope mechanism.

One end of the pawl is fixedly connected to one end of the spring, and the other end of the spring is fixedly connected to the winding winch. An unlocking assembly is installed on the pawl and the winding winch.

[0010] Furthermore, the cable laying and traction assembly includes a uniform cable laying assembly and a traction assembly. The uniform cable laying assembly is mounted on a rotating mounting platform, and the traction assembly is mounted on the moving end of the uniform cable laying assembly.

[0011] Furthermore, the rope pressing assembly includes a support platform, a fixed shaft, and three sets of rotary pressing modules. The support platform is fixedly mounted on a rotary mounting platform, and a fixed shaft is fixedly mounted on the support platform. Three sets of rotary pressing modules are evenly installed on the fixed shaft at equal intervals.

[0012] Furthermore, the alternating adjustment assembly includes an adjustment motor, a synchronous shaft, an intermittent transmission assembly, and a staggered transmission assembly.

[0016] Compared with the prior art, the advantages of this invention are as follows: 1. The cable laying direction is adjusted by the rotating support mechanism to align it with the corresponding connection position of the cable, thereby effectively reducing cable bending; in the non-use state, the winding assembly is locked by the protective component to ensure the stability of the winding assembly; the winding assembly, together with the cable laying traction component, realizes the cable laying. During this process, the winding assembly is protected by the protective component, and the winding assembly is locked in time if abnormal cable laying occurs; the cable is supported and guided by the slack rope adjustment component to avoid cable bending; after the cable laying is completed, the cable end is connected to the shore power at the dock, and power transmission is ensured by connecting the electrical box and the cable; during this process, the tension of the cable is detected by the tension sensor on the lower side of the slack rope adjustment component. If the tension decreases, it indicates that the cable is slack. At this time, the slack rope adjustment component is used to adjust the cable to tighten it again to avoid wear caused by cable slack; if the cable is taut, the slack rope adjustment component is used to adjust it to avoid the cable being overly tight; 2. The winding assembly, in conjunction with the cable traction assembly, winds up the cable. The cable traction assembly evenly arranges the cable within the winding assembly, and then the cable pressing assembly compresses the cable, ensuring a tight and uniform arrangement. After one layer is wound and compressed, the alternating adjustment assembly drives the cable pressing assembly for adjustment, further ensuring uniform compression of each layer of cable on the winding assembly. During this process, a protective assembly restricts the unidirectional rotation of the winding assembly, preventing excessive weight of the unwound cable from causing the winding assembly to unwind when the winding process begins.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. The terms "left," "right," "front," "rear," "up," and "down" mentioned in the following description are oriented according to the perspective of a front view.

[0029] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-3 A cable winch with a slack rope protection structure includes a base 1, a rotating support mechanism 2, a connecting electrical box 3, and a cable winding and unwinding mechanism 4; it also includes an anti-slack rope mechanism 5. The rotating support mechanism 2 is mounted on the base 1, and the moving end of the rotating support mechanism 2 is equipped with a cable winding and unwinding mechanism 4 and an anti-loosening rope mechanism 5. like Figure 2As shown, the cable winding and unwinding mechanism 4 includes a winding assembly 41, a protective assembly 42, and a cable traction assembly 43. The winding assembly 41 is installed on the moving end of the rotating support mechanism 2, and the protective assembly 42 is installed on the winding assembly 41. The moving end of the rotating support mechanism 2 is equipped with a cable traction assembly 43 for evenly arranging the cable on the winding assembly 41. The connecting electrical box 3 is installed on the winding assembly 41, and one end of the cable is electrically connected to the connecting electrical box 3 through a conductive slip ring. like Figure 2 As shown, the anti-slack rope mechanism 5 includes a rope pressing assembly 51, an alternating adjustment assembly 52, and a slack rope adjustment assembly 53. The moving end of the rotary support mechanism 2 is equipped with a rope pressing assembly 51 for assisting in the uniform laying of the cable on the winding assembly 41; the rope pressing assembly 51 is equipped with an alternating adjustment assembly 52 for adjusting the position of the rope pressing assembly 51; the moving end of the rotary support mechanism 2 is equipped with a slack rope adjustment assembly 53 for adjusting the slack state of the cable after unfolding; and a tension sensor for detecting cable tension is installed on the lower side of the slack rope adjustment assembly 53.

[0030] In this embodiment, when the cable winch with slack rope protection structure is working normally, after the ship docks, the cable laying direction is adjusted by the rotating support mechanism 2 to align it with the corresponding connection position of the cable, thereby effectively reducing cable bending. In the non-use state, the winding assembly 41 is locked by the protective component 42 to ensure the stability of the winding assembly 41. The winding assembly 41, in conjunction with the cable laying traction component 43, realizes the cable laying. During this process, the protective component 42 protects the winding assembly 41. If abnormal cable laying occurs, the winding assembly 41 is promptly adjusted. Component 41 is locked; the cable is supported and guided by the slack rope adjustment component 53 to prevent cable bending; after the cable is laid out, the cable end is connected to the shore power at the dock, and power transmission is ensured by connecting the electrical box 3 and the cable; during this process, the tension of the cable is detected by the tension sensor on the lower side of the slack rope adjustment component 53. If the tension decreases, it indicates that the cable is slack. At this time, the slack rope adjustment component 53 is used to adjust the cable to tighten it again to prevent the cable from being slack and causing wear; if the cable is taut, the slack rope adjustment component 53 is used to adjust it to prevent the cable from being overly taut; After use, the cable is disconnected from the shore power at the dock. Then, the winding assembly 41, in conjunction with the cable traction assembly 43, winds the cable. The cable is evenly arranged by the winding assembly 41 through the cable traction assembly 43, and then the cable is pressed tightly by the pressing rope assembly 51 to make the cable tightly and evenly arranged. After one layer is wound and pressed, the pressing rope assembly 51 is adjusted by the alternating adjustment assembly 52 to further ensure that the pressing force on each layer of cable on the winding assembly 41 is uniform. During this process, the protective assembly 42 restricts the unidirectional rotation of the winding assembly 41 to prevent the weight of the unwound cable from causing the winding assembly 41 to unwind when the winding starts.

[0031] Example 2: In some embodiments, as a preferred embodiment of the present invention, such as... Figure 2 and Figure 6 As shown, the rotating support mechanism 2 includes a rotating mounting platform 21, an arc-shaped rack 22, a drive gear 23, and a rotating drive motor 24. The left end of the rotating mounting platform 21 is rotatably mounted on the base 1, and the arc-shaped rack 22 is fixedly mounted on the bottom right end of the rotating mounting platform 21. The rotating drive motor 24 is fixedly mounted on the base 1, and the drive gear 23 is fixedly mounted on the output end of the rotating drive motor 24. The drive gear 23 meshes with the arc-shaped rack 22. The rotary drive motor 24 drives the drive gear 23 to rotate, and the drive gear 23 drives the rotary drive motor 24 to move, thereby driving the rotary mounting platform 21 to rotate; the direction of the rotary mounting platform 21 is changed so that the cable laying direction on the rotary mounting platform 21 is aligned with the cable connection point.

[0032] like Figures 3-5 As shown, the winding assembly 41 includes a support base 411, a winding winch 412, a support frame 413, and a reduction motor 414.

The connecting box 3 is fixedly connected to the support base 411. The support frame 413 is fixedly installed on the rotary mounting platform 21, and the reduction motor 414 is fixedly mounted on the support frame 413. The output end of the reduction motor 414 is fixedly connected to the winding winch 412. The protective assembly 42 includes a ratchet 421, a pawl 422, a spring 423, and an unlocking assembly. The ratchet 421 is fixedly mounted on the support base 411. Multiple pawls 422 are evenly and rotatably mounted in a circular array on the side of the winding winch 412. One end of the pawl 422 is fixedly connected to one end of the spring 423, and the other end of the spring 423 is fixedly connected to the winding winch 412. The unlocking assembly is mounted on the pawl 422 and the winding winch 412. The unlocking assembly includes a magnetic block 424 and an electromagnet 425. The magnetic block 424 is fixedly mounted on the pawl 422, and the electromagnet 425 for attracting the magnetic block 424 is fixedly mounted on the winding winch 412. The cable laying and traction assembly 43 includes a uniform cable laying assembly and a traction assembly. The uniform cable laying assembly is mounted on the rotary mounting platform 21, and the traction assembly is mounted on the moving end of the uniform cable laying assembly. The uniform cable laying assembly includes a second support frame 431, a cable laying straight module 432, and a mounting plate 433. The second support frame 431 is fixedly mounted on the rotating mounting table 21. The cable laying straight module 432 is fixedly mounted on the second support frame 431. The moving end of the cable laying straight module 432 is fixedly mounted on the mounting plate 433. The traction assembly includes a fixed housing 434, a linear module 435, a movable housing 436, a traction wheel 437, a pressure wheel 438, and a traction motor 439. The fixed housing 434 is fixedly installed on one side of the mounting plate 433, and the linear module 435 is fixedly installed on the other side of the mounting plate 433. The movable end of the linear module 435 is fixedly installed with the movable housing 436. Two traction wheels 437 are rotatably installed inside the fixed housing 434. A pressure wheel 438 for pressing the cable with the traction wheels 437 is rotatably installed inside the movable housing 436. The two traction wheels 437 are connected to the synchronous belt pulley via a synchronous belt. The traction motor 439 is fixedly installed on the fixed housing 434, and the output end of the traction motor 439 is fixedly connected to one of the traction wheels 437.

[0033] The geared motor 414 drives the winding winch 412 to rotate, causing the cable to wind up; the linear module 435 drives the movable housing 436 to move horizontally, thereby driving the traction wheel 437 to move closer to the pressure wheel 438. The traction wheel 437 and the pressure wheel 438 press the cable together. The traction motor 439 drives the traction wheel 437 to rotate, thereby achieving cable traction through the traction wheel 437 and the pressure wheel 438; the cable laying linear module 432 drives the mounting plate 433 to move to one side of the winding winch 412, and the mounting plate 433 drives the fixed housing. 434, linear module 435, movable housing 436, traction wheel 437, pressure wheel 438, and traction motor 439 move horizontally, thereby driving the cable between traction wheel 437 and pressure wheel 438 to move horizontally; the cable is wound on the winding winch 412, so that the winding position of the cable moves from one side of the winding winch 412 to the other side. After the cable is fully laid on the winding winch 412, the cable laying linear module 432 drives the mounting plate 433 to move to the other side of the winding winch 412; thus realizing the winding of the cable.

[0034] Example 3: In some embodiments, as a preferred embodiment of the present invention, such as Figures 7-9 As shown, the rope pressing assembly 51 includes a support platform 511, a fixed shaft 512, and three sets of rotary pressing modules. The support platform 511 is fixedly installed on the rotary mounting platform 21, and the fixed shaft 512 is fixedly installed on the support platform 511. Three sets of rotary pressing modules are evenly installed on the fixed shaft 512 at equal intervals. The rotary clamping module includes a rotating frame 513, guide rods 514, spring 515, mounting frame 516, and pressure roller 517. The lower end of the rotating frame 513 is rotatably mounted on a fixed shaft 512, and the upper end of the rotating frame 513 is slidably connected to multiple guide rods 514. The guide rods 514 are fixedly mounted on the same mounting frame 516 on the side closest to the support base 411. Spring 515 is sleeved on the guide rods 514. One end of spring 515 is fixedly connected to the rotating frame 513, and the other end of spring 515 is fixedly connected to the mounting frame 516. A pressure roller 517 for clamping cables is rotatably mounted on the mounting frame 516. The alternating adjustment assembly 52 includes an adjustment motor 521, a synchronous shaft 522, an intermittent transmission assembly, and an interleaved transmission assembly. The adjustment motor 521 is fixedly mounted on the support platform 511, and the synchronous shaft 522 is rotatably mounted on the support platform 511. The output end of the adjustment motor 521 is fixedly connected to the synchronous shaft 522. An intermittent transmission assembly is mounted on the rotating frame 513. Three sets of interleaved transmission assemblies are evenly installed at equal intervals on the synchronous shaft 522 to drive the rotating frame 513 to rotate sequentially through the intermittent transmission assembly. The intermittent transmission assembly and the interleaved transmission assembly slide in contact with each other. The intermittent transmission assembly includes a rotating transmission disk 523, which is fixedly installed on the lower side of the rotating frame 513. The rotation center of the rotating transmission disk 523 coincides with that of the rotating frame 513. The edge of the rotating transmission disk 523 is provided with a plurality of arc-shaped limiting grooves 524 evenly spaced in a circular array, and a driving groove 525 is provided between adjacent arc-shaped limiting grooves 524. The staggered transmission assembly includes a mounting plate 526, a limiting plate 527, and a drive rod 528. The mounting plate 526 is fixedly mounted on the synchronous shaft 522, and the limiting plate 527 is fixedly mounted on the mounting plate 526. The limiting plate 527 slides in contact with the arc-shaped limiting groove 524. The drive rod 528 is fixedly mounted on the edge of the mounting plate 526. The drive rod 528 slides in contact with the drive groove 525. The drive rods 528 on the three mounting plates 526 are staggered. The slack rope adjustment assembly 53 includes a support frame three 531, a linear module two 532, an arc-shaped support frame 533, and guide rollers 534. The support frame three 531 is fixedly installed on the rotary mounting table 21. The linear module two 532 is fixedly installed on the support frame three 531. The arc-shaped support frame 533 is fixedly installed at the output end of the linear module two 532. Guide rollers 534 are evenly rotated and installed in a circumferential array on the arc-shaped support frame 533. The tension sensor is fixedly installed on the lower side of the arc-shaped support frame 533. Linear module 2 532 and linear module 1 435 are both configured as cylinder linear modules.

[0035] In this embodiment, the adjusting motor 521 drives the synchronous shaft 522 to rotate, and the synchronous shaft 522 drives the mounting plate 526, the limiting plate 527, and the drive rod 528 to rotate. When the limiting plate 527 on the mounting plate 526 is in contact with the corresponding arc-shaped limiting groove 524, it limits the rotation transmission plate 523. At this time, the rotating frame 513 does not rotate. At this time, the second spring 515 on the rotating frame 513 is compressed, and the restoring force of the second spring 515 presses the mounting frame 516, thereby driving the pressure roller 517 to press the cable. The cable continues to be wound up until the cable is fully wound on the winding reel 412. The adjusting motor 521 drives the mounting plate 526 to rotate via the synchronous shaft 522. At this time, the drive rod 528 on one mounting plate 526 moves into the corresponding drive groove 525. The rotation of the mounting plate 526 drives the rotating transmission plate 523 to rotate via the drive rod 528 and the drive groove 525. At this time, the limiting plate 527 disengages from the arc-shaped limiting groove 524, thereby driving the rotating frame 513 to rotate. This causes the guide rod 514, spring 515, mounting frame 516, and pressure roller 517 on the rotating frame 513 to move away from the support base 411. This ensures the spacing between the rotating frame 513 and the cable during the second layer of cable laying, and thus ensures the clamping force of the pressure roller 517 on the cable. Consistent; at this time, due to the staggered arrangement of the drive rods 528, the other two drive rods 528 have not moved into the drive groove 525, so that the other two pressure rollers 517 still press the first layer of cable until the second layer of cable is laid in the corresponding position. The adjusting motor 521 continues to drive the mounting plate 526 to rotate through the synchronous shaft 522, so that the corresponding drive rods 528 and drive grooves 525 drive the rotating transmission plate 523 to rotate, thereby driving the rotating frame 513 to rotate. In the above way, the distance between the three rotating frames 513 and the support base 411 is adjusted in sequence to ensure that the cable is pressed throughout the entire process of cable laying; and to ensure that the pressing force of the pressure rollers 517 on each layer of cable is the same. Simultaneously, when the unfolded cable is relaxed, the linear module 2 532 drives the arc support frame 533 and guide roller 534 to move to the upper right, thereby causing the cable to unfold outward and lift it, so that the cable is no longer relaxed; if the cable is taut, the linear module 2 532 drives the arc support frame 533 and guide roller 534 to move to the lower left, thereby causing the cable to converge inward and move downward, so that the cable is no longer taut; thus realizing the adjustment of the cable tension.

[0036] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
