Technical Field
[0001] The invention relates to the technical field related to cables, and in particular to a twisted structure of a three-core cable. Background Art
[0002] Cable is an important carrier for transmitting electric energy, signals and data. In the field of electric power, it transmits the electric energy generated by power plants to various power consumption areas, providing a stable power supply for industrial production, commercial activities and residents' lives. In the field of communications, cables are used to transmit voice, image and data signals, realizing information exchange on a global scale. In addition, cables are also widely used in many industries such as transportation, petrochemicals, aerospace, etc. In the early days, cables mainly used natural materials such as rubber and silk as insulation layers and sheaths. The performance of these materials was limited, and the transmission capacity of the cables was small and the life was short. With the advancement of science and technology, synthetic materials such as polyethylene and polyvinyl chloride have gradually been used in cable manufacturing. These materials have better insulation properties, mechanical strength and corrosion resistance, which greatly improves the quality and reliability of cables. In recent years, with the continuous improvement of cable performance requirements, new materials and technologies have continued to emerge. For example, cables made of superconducting materials can achieve large-capacity and low-loss power transmission; optical fiber cables play a huge advantage in the field of communications, with the characteristics of high speed, large capacity, and anti-interference. In order to improve the performance of the cables, they need to be twisted. Therefore, a twisted structure of a three-core cable is particularly needed.
[0003] However, the existing cable twisting device will generate vibration during the wire-winding process, whether it is manual or automatic. The vibration may cause frequent friction between the contact parts of the cable and the wire-winding device, thereby damaging the insulation layer of the cable, reducing the insulation performance of the cable, and increasing safety risks such as leakage. At the same time, the vibration will cause the wire arrangement of the wire-winding device to be uneven, resulting in uneven arrangement of the cables on the wire-winding reel, affecting subsequent use and storage.

The upper surface of the workbench 1 is fixedly connected with the buffer box 801, the inner wall of the buffer box 801 is slidably connected with the support rod 802, the interior of the support rod 802 is provided with a mounting groove 803, the inner wall surface of the mounting groove 803 is slidably connected with the block 804, and the inner wall surface of the mounting groove 803 is installed with the wire-taking reel 805. A fixing hole 806 is provided on one side surface of the support rod 802, and a second telescopic spring 807 is fixedly connected to the outer surface of the fixing hole 806, a stopper 808 is fixedly connected to one end surface of the second telescopic spring 807, and a limiting rod 809 is fixedly connected to the inner surface of the stopper 808, a rocker 810 is fixedly connected to one end surface of the take-up reel 805, and a handle 811 is fixedly connected to one end of the rocker 810, a shock-absorbing pad 812 is fixedly connected to the bottom surface of the inner wall of the buffer box 801, a bottom plate 813 is fixedly connected to the upper surface of the shock-absorbing pad 812, a buffer groove 814 is fixedly connected to the upper surface of the bottom plate 813, a telescopic tube 815 is fixedly connected to the bottom surface of the inner wall of the buffer groove 814, and a telescopic rod is slidably connected to the inner wall surface of the telescopic tube 815 816, a buffer spring 817 is wound around the outer wall surface of the telescopic rod 816, and sliding grooves 818 are provided on the two side surfaces of the inner wall of the buffer groove 814. The inner wall of the buffer groove 814 is slidably connected with a buffer block 819, and the two side surfaces of the buffer block 819 are fixedly connected with a slider 820. Through the setting of the wire-winding mechanism 8, first, the wire-winding drum 805 is installed in the installation groove 803 of the support rod 802, and the block 804 slides on the inner wall surface of the installation groove 803 to assist in fixing the wire-winding drum 805 to prevent it from shaking during the wire-winding process. After the installation is completed, the stopper 808 is pulled to align the limiting rod 809 with the fixing hole 806. Under the action of the second telescopic spring 807, the limiting rod 809 is inserted into the fixing hole 806 to further fix it. The wire take-up drum 805 ensures its stability when taking up the wire. Then, the operator holds the handle 811 and turns the rocker 810 to drive the wire take-up drum 805 to rotate and start taking up the wire. During the process of taking up the wire, vibration may be generated due to the continuous winding of the cable. At this time, the shock absorbing device in the buffer box 801 starts to play a role. When the vibration is transmitted to the support rod 802, the support rod 802 slides on the inner wall of the buffer box 801 and transmits the vibration to the bottom plate 813. In the buffer groove 814 above the bottom plate 813, the telescopic rod 816 slides on the inner wall surface of the telescopic tube 815. At the same time, the buffer spring 817 is compressed or stretched to absorb part of the vibration energy. The sliders 820 on both sides of the buffer block 819 slide in the slide groove 818 to further enhance the buffering effect.The shock-absorbing pad 812 can also reduce the vibration transmission and the influence of the vibration on the take-up mechanism 8. The take-up mechanism 8 can effectively reduce the vibration during the take-up process, improve the stability and quality of the take-up, and ensure that the three-core cable can be neatly and tightly wound on the take-up drum 805.
[0020] Furthermore, multiple groups of support legs 2 are arranged at the bottom of the workbench 1, and foot pads 3 are evenly distributed at the bottom of each group of support legs 2. Through the arrangement of the support legs 2 and the foot pads 3, multiple groups of support legs 2 jointly support the workbench 1, so that the workbench 1 is more stable when bearing various forces in the cable twisting process, whether it is the vibration generated by the operation of the twisting mechanism 4, or the reaction force of the take-up mechanism 8 on the workbench during the take-up process, the multiple groups of support legs 2 can effectively disperse these forces to prevent the workbench 1 from shaking or tilting, and the evenly distributed foot pads 3 further increase the contact area between the support legs 2 and the ground, thereby improving the stability of the support. At the same time, the foot pads 3 can play an anti-slip role, ensuring that the entire equipment will not be displaced due to slight vibrations of the ground or external forces during operation, thereby ensuring the continuity and accuracy of the cable twisting work.
[0021] Furthermore, the twisting mechanism 4 includes a bracket 401, a first motor 402, a rotating shaft 403, a roller 404, a wire-releasing reel 405, a first guide plate 406, a second guide plate 407, a tension wheel 408, an adjusting rod 409, a fixing rod 410, a telescopic hole 411, a first telescopic spring 412, a limiting plate 413, a limiting block 414 and an adjusting hole 415. The upper surface of one end of the workbench 1 is fixedly connected to the bracket 401, the upper surface of the bracket 401 is fixedly connected to the first motor 402, the inner surface of the first motor 402 is fixedly connected to the rotating shaft 403, one end surface of the rotating shaft 403 is fixedly connected to the roller 404, and one end outer wall surface of the roller 404 is fixedly connected to the inner surface of the first motor 402. A wire unwinding drum 405 is fixedly connected to the surface of the drum 404, a first guide plate 406 is fixedly connected to the outer wall surface of the drum 404, a second guide plate 407 is fixedly connected to the other end surface of the drum 404, a tension wheel 408 is arranged on the inner wall surface of the first guide plate 406, adjusting rods 409 are rotatably connected to the two sides of the first guide plate 406, a fixing rod 410 is slidably connected to the outer wall surface of the adjusting rod 409, a telescopic hole 411 is provided on the inner wall surface of the adjusting rod 409, a first telescopic spring 412 is fixedly connected to one end surface of the inner wall of the telescopic hole 411, one end of the first telescopic spring 412 is fixedly connected to a limiting plate 413, and one end surface of the limiting plate 413 is fixedly connected to a limiting block 414 , an adjustment hole 415 is provided on the inner surface of the fixing rod 410. Through the setting of the twisting mechanism 4, first, the first motor 402 is started, driving the rotating shaft 403 to rotate, thereby rotating the drum 404, and the unwinding drum 405 fixed on the outer wall surface of one end of the drum 404 also rotates accordingly, and begins to release the cable core wire. As the drum 404 rotates, the cable core wire passes through the first guide plate 406 and the second guide plate 407 in turn. The tension wheel 408 on the first guide plate 406 plays a role in adjusting the tension of the cable core wire. When the tension of the cable core wire changes, the tension wheel 408 will move within a certain range according to the size of the tension. If the position of the tension wheel 408 needs to be adjusted, This can be achieved through the adjustment rod 409, which slides in the fixed rod 410. When the position of the adjustment rod 409 needs to be fixed, the first telescopic spring 412 in the telescopic hole 411 pushes the limit plate 413, so that the limit block 414 extends out and is stuck in the adjustment hole 415 on the inner surface of the fixed rod 410, thereby fixing the position of the adjustment rod 409. During the twisting process, different cable cores are driven by the roller 404 and guided by the first guide plate 406 and the second guide plate 407 to be twisted at a specific angle and speed to form a three-core cable. During the entire twisting process, the twisting mechanism 4 ensures the twisting quality and stability of the cable cores through precise control and adjustment.
[0022] Furthermore, the rotating shaft 403 cooperates with the drum 404 through the first motor 402 to form a rotating structure. There are three groups of pay-off drums 405 evenly spaced on the surface of the drum 404. Through the arrangement of the pay-off drums 405, the three groups of pay-off drums 405 evenly spaced can make the cable core wires evenly stressed during the twisting process, and maintain a consistent twisting angle and tension. This can avoid problems such as twisting and loosening of the cable core wires due to uneven stress, thereby ensuring the twisting quality of the three-core cable. In addition, the stable rotating structure can ensure that the pay-off speed of the pay-off drum 405 is even and stable, further improving the twisting accuracy and quality.
[0023] Furthermore, the limit plate 413 cooperates with the limit block 414 through the first telescopic spring 412 to form a telescopic structure, and multiple groups of adjustment holes 415 are arranged on the inner side of the fixed rod 410. Through the setting of the adjustment holes 415, multiple options are provided for adjusting the position of the tension wheel 408. In this way, the position of the tension wheel 408 can be flexibly adjusted according to different specifications of cable cores and twisting requirements to achieve the best twisting effect. Whether it is a thinner cable core or a thicker cable core, the position of the tension wheel 408 can be adjusted to adapt to its different tension requirements, thereby improving the versatility and adaptability of the equipment.
[0024] Furthermore, the sealing mechanism 7 includes a fixed seat 701, a second motor 702, a transmission shaft 703, a first roller 704, a crawler 705, a connecting plate 706, a second roller 707 and a film 708. The upper surface of one end of the workbench 1 is fixedly connected to the fixed seat 701, the upper surface of the fixed seat 701 is fixedly connected to the second motor 702, one end surface of the second motor 702 is fixedly connected to the transmission shaft 703, one end surface of the transmission shaft 703 is fixedly connected to the first roller 704, the outer wall surface of the first roller 704 is attached to the crawler 705, one end of the support 5 is fixedly connected to the connecting plate 706, the inner wall surface of the other end of the crawler 705 is attached to the second roller 707, one end of the second roller 707 is rotatably connected to the surface of the connecting plate 706, and the outer surface of one end of the second roller 707 is fixedly connected to the film 708. With the setting of mechanism 7, the second motor 702 is started, driving the transmission shaft 703 to rotate, and the transmission shaft 703 then drives the first roller 704 to rotate. The rotation of the first roller 704 causes the track 705 attached to its outer wall surface to start moving, and the movement of the track 705 drives the second roller 707 attached to the inner wall surface of the other end to rotate. Since the outer surface of one end of the second roller 707 is fixedly connected with a film 708, as the second roller 707 rotates, the film 708 also starts to rotate synchronously. In this process, the film 708 can evenly attach a specific sealing material to the surface of the cable that needs to be sealed. At the same time, the connecting plate 706 provides a stable support for the second roller 707 to ensure that it maintains a stable position and state during rotation. The entire sealing mechanism 7 achieves efficient and precise sealing operations through the coordinated action of various components.
[0025] Furthermore, multiple groups of film rolls 708 are arranged on the surface of the second roller 707, and are evenly spaced about the center of the second roller 707. Through the arrangement of the film rolls 708, when the cable passes through the sealing mechanism 7, the glue can be obtained from multiple film rolls 708 at the same time, which greatly increases the contact area between the glue and the cable and the uniformity of the coating. Multiple groups of film rolls 708 can complete the sealing process of the cable in a shorter time, thereby improving the sealing efficiency. At the same time, the evenly spaced distribution ensures the uniform coverage of the glue on the cable surface, enhances the quality of the sealing layer, and improves the insulation, waterproof and corrosion resistance of the cable.
[0026] Furthermore, the stopper 808 cooperates with the limiting rod 809 through the second telescopic spring 807 to form a telescopic structure. The outer wall size of the limiting rod 809 is consistent with the inner wall size of the fixing hole 806. Through the setting of the fixing hole 806 and the limiting rod 809, the limiting rod 809 can be tightly inserted into the fixing hole 806 to prevent the wire reel 805 from shaking or shifting during the wire reeling process. This precise cooperation ensures the stability of the wire reel 805, ensures that the cable can be neatly wound on the wire reel 805, and improves the quality and efficiency of wire reeling.
[0027] Furthermore, the surface of the handle 811 is provided with anti-slip grooves, one end of the buffer spring 817 is fixedly connected to the top of the telescopic tube 815, and the other end is fixedly connected to the bottom of the buffer block 819. The anti-slip grooves and the buffer spring 817 are provided to increase the friction between the operator's hand and the handle 811, so that when the rocker 810 is turned to perform the line-reeling operation, the handle 811 is not easy to slip out of the hand, thereby improving the convenience and safety of the operation. The operator can hold the handle 811 more stably, accurately control the line-reeling speed and tension, and ensure the smooth progress of the line-reeling process.
[0028] Furthermore, the outer wall size of the telescopic rod 816 matches the inner wall size of the telescopic tube 815, and the outer wall size of the slider 820 matches the inner wall size of the slide groove 818. Through the setting of the slide groove 818 and the slider 820, the buffer block 819 can slide smoothly in the buffer groove 814, further enhancing the buffering effect. This size matching ensures the stability and buffering performance of the wire-winding mechanism 8 during operation, and improves the quality and efficiency of wire-winding.
[0029] Working principle: First, the three cable cores to be twisted are respectively installed on the pay-off drum 405 of the twisting mechanism 4, and the first motor 402 is started to drive the rotating shaft 403 to rotate, thereby rotating the drum 404, and the pay-off drum 405 fixed on the outer wall surface of one end of the drum 404 also rotates accordingly, and begins to release the cable core. As the drum 404 rotates, the cable core passes through the first guide plate 406 and the second guide plate 407 in turn. The tension wheel 408 on the first guide plate 406 plays a role in adjusting the tension of the cable core. When the tension of the cable core changes, the tension wheel 408 will move within a certain range according to the size of the tension. If the position of the tension wheel 408 needs to be adjusted, it can be achieved through the adjusting rod 409. The adjusting rod 409 is fixed The first telescopic spring 412 in the telescopic hole 411 pushes the limit plate 413 to make the limit block 414 extend and fit into the adjustment hole 415 on the inner surface of the fixing rod 410, thereby fixing the position of the adjusting rod 409. During the twisting process, different cable cores are driven by the roller 404 and guided by the first guide plate 406 and the second guide plate 407 to be twisted at a specific angle and speed to form a three-core cable. During the whole twisting process, the twisting mechanism 4 ensures the twisting quality and stability of the cable cores through precise control and adjustment. The twisted cable passes through the tightening wheel 6 on the support 5, and the tightening wheel 6 performs preliminary tightening and sorting on the cable to make the cable tighter and neater. The second motor 702 is then started, driving the transmission shaft 703 to rotate, and the transmission shaft 703 in turn drives the first roller 704 to rotate. The rotation of the first roller 704 causes the crawler belt 705 attached to its outer wall surface to start moving, and the movement of the crawler belt 705 drives the second roller 707 attached to the inner wall surface of the other end to rotate. Since the outer surface of one end of the second roller 707 is fixedly connected with a film 708, as the second roller 707 rotates, the film 708 also starts to rotate synchronously. In this process, the film 708 can evenly attach a specific sealing material to the surface of the cable that needs to be sealed. At the same time, the connecting plate 706 provides a stable support for the second roller 707 to ensure that it maintains a stable position and state during the rotation process. The sealing mechanism 7 realizes efficient and accurate sealing operation through the coordinated action of various components. The wire take-up drum 805 is installed in the installation groove 803 of the support rod 802. The block 804 slides on the inner wall surface of the installation groove 803 to assist in fixing the wire take-up drum 805 to prevent it from shaking during the wire taking-up process. After the installation is completed, the stopper 808 is pulled to align the limit rod 809 with the fixing hole 806. Under the action of the second telescopic spring 807, the limit rod 809 is inserted into the fixing hole 806 to further fix the wire take-up drum 805 and ensure its stability during wire taking-up. Then, the operator holds the handle 811 and turns the rocker 810 to drive the wire take-up drum 805 to rotate and start the wire taking-up work. During the wire taking-up process, due to the continuous winding of the cable,Vibration may occur. At this time, the shock absorbing device in the buffer box 801 begins to work. When the vibration is transmitted to the support rod 802, the support rod 802 slides on the inner wall of the buffer box 801 and transmits the vibration to the bottom plate 813. In the buffer groove 814 above the bottom plate 813, the telescopic rod 816 slides on the inner wall surface of the telescopic tube 815. At the same time, the buffer spring 817 is compressed or stretched to absorb part of the vibration energy. The sliders 820 on both sides of the buffer block 819 slide in the slide groove 818 to further enhance the buffering effect. The shock absorbing pad 812 can also play a role in reducing vibration transmission and reducing the impact of vibration on the take-up mechanism 8. The take-up mechanism 8 can effectively reduce vibration during the take-up process, improve the stability and quality of the take-up, and ensure that the three-core cable can be neatly and tightly wound on the take-up drum 805. The model of the first motor 402 is Y315S-2, and the model of the second motor 702 is YE2-132S-4. In this way, the use process of a three-core cable twisted structure is completed.
