Description

Technical Field

[0001] The invention relates to the technical field of cable processing, in particular to a cable main insulation layer reaction force cone processing device. Background Art

[0002] High-voltage direct current (HVDC) transmission boasts high transmission efficiency and minimal energy loss. Because it's more economical than AC transmission, it's widely used for long- and ultra-long-distance power transmission. However, due to limitations in high-voltage cable manufacturing, the maximum length a cable can be manufactured without joints is 10 km. For ultra-long-distance transmission, single cable joints must be processed to allow multiple cables to be spliced ​​together. At the cable joint, the electric field distribution of the cable's main insulation and supplementary insulation differs from that of the cable itself, creating a potential difference between adjacent points on the same insulation layer. This creates an axial field strength, and consequently, axial stress. Therefore, the insulation layer near the conductor connection is typically cut into a tapered surface, known as a reaction cone. This is then wrapped with additional insulation, creating stress cones at both ends of the additional insulation. This altered potential distribution on the insulation surface promotes a uniform electric field and ensures a secure joint.

[0003] To ensure adequate safety, the reaction cone requires high-quality molding. Currently, it is mostly done manually, cutting it from glass sheets. This method is time-consuming and labor-intensive, and the resulting reaction cones are of poor quality and difficult to standardize. Although some devices have emerged to assist manual reaction cone cutting, these devices are often cumbersome to operate, inefficient, and can only serve as an auxiliary tool.

[0037] The present invention provides a cable main insulation layer reaction force cone processing equipment, which can realize the automatic processing of reaction force cones of different sizes and has good molding quality. Figure 1 and Figure 2 As shown, the cable main insulation layer reaction force cone processing equipment includes a support seat 1, a clamping device 2, a cutting device 3 and a transverse feeding device 4, and the clamping device 2, cutting device 3 and transverse feeding device 4 are all installed on the support seat 1.

[0038] like Figure 1 As shown, the clamping device 2 is installed on the support base 1, and two groups of clamping devices 2 can be set. The two groups of clamping devices 2 are respectively arranged at both ends of the support base 1 to clamp and fix the cable 10. Figure 3 and Figure 4 As shown, the clamping device 2 includes a clamping bracket 21 and two clamping claws 22 slidably arranged on the clamping bracket 21. The two clamping claws 22 can move closer to each other to clamp the cable 10, or move away from each other to release the clamping of the cable 10. In this embodiment, the two clamping claws 22 slide by the following structure: Figure 3 and Figure 4 The clamping device 2 further includes a rotatable rocker 25, a clamping gear 23 fixed to the end of the rocker 25, and clamping racks 24 disposed on either side of the clamping gear 23 and meshing with the clamping gear 23. The clamping racks 24 are disposed vertically, and each clamping jaw 22 is fixed to one end of a clamping rack 24. By rotating the rocker 25, the rocker 25 drives the clamping gear 23 to rotate, thereby causing the clamping rack 24 to move upward or downward, and the clamping rack 24 in turn drives the clamping jaw 22 to move upward or downward. It should be noted that in this embodiment, because the two clamping racks 24 are disposed on either side of the clamping gear 23, the two clamping racks 24 can move in opposite directions, thereby achieving the purpose of moving the two clamping jaws 22 closer to or away from each other.

[0039] like Figure 4 As shown, the clamping jaw 22 may preferably be a plate-shaped structure, and may be V-shaped or arc-shaped to match the shape of the cable 10 .

[0040] In this embodiment, the rocker 25 can be rotated manually, that is, the clamping jaws 22 can be tightened or loosened directly by manually shaking the rocker 25. The rocker 25 can also be rotated by a driving member such as a motor.

[0041] Furthermore, the clamping device 2 of this embodiment also includes a locking bolt 26, which can lock the position of the rocker 25 to fix the position of the clamping jaws 22, thereby making the clamping jaws 22 more stable and reliable in clamping the cable 10. The locking bolt 26 can lock the rocker 25 by pressing the end of the locking bolt 26 against the rocker 25 to prevent it from rotating, or other structures can be used in conjunction with the locking bolt 26 to lock the rocker 25.

[0042] In this embodiment, the cutting device 3 is slidably mounted on the support 1, and can cut the cable 10 to form the required reaction force cone. Figure 5-9 As shown, the cutting device 3 includes a cutting frame 30, a drive assembly 31 mounted on the cutting frame 30, and a cutting tool 32 driven by the drive assembly 31. The drive assembly 31 is capable of driving the cutting tool 32 to rotate and move radially along the cable 10 to adjust the cutting depth. Exemplarily, the drive assembly 31 includes a first drive member 311, a second drive member 312, and a planetary gear set 313. The cutting tool 32 is driven to rotate and move radially along the cable 10 by the planetary gear set 313. The first drive member 311 and the second drive member 312 jointly drive the planetary gear set 313 to rotate, which in turn drives the cutting tool 32 to rotate. Furthermore, the first drive member 311 and the second drive member 312 can also cause the planetary gear set 313 to drive the cutting tool 32 to move radially along the cable 10 to adjust the cutting depth.

[0043] like Figure 5-9 As shown, preferably, the above-mentioned planetary gear set 313 includes a planetary carrier 3131, a fixed gear 3132, a ring gear 3133, a planetary gear 3134 and a tool driving gear 3135, wherein one end of the above-mentioned fixed gear 3132 rotates through the cutting frame body 30 and is supported by the cutting frame body 30, and the end of the fixed gear 3132 is driven to rotate by the first driving member 311, and the above-mentioned planetary carrier 3131 is fixedly sleeved on the other end of the fixed gear 3132 to rotate with the fixed gear 3132, and the planetary carrier 3131 is used to support the ring gear 3133 and the planetary gear 3134.

[0044] For example, Figure 8As shown, the fixed gear 3132 can be a columnar structure. The drive assembly 31 of this embodiment can also include a power input gear 314 and a first transmission gear 315. The power input gear 314 meshes with the first transmission gear 315. The first transmission gear 315 is fixedly connected to the output end of the first driving member 311. The power input gear 314 is fixedly connected to one end of the fixed gear 3132 via fasteners such as bolts, which can drive the fixed gear 3132 to rotate at the same speed. In this embodiment, the fixed gear 3132 is only equipped with teeth at the end away from the power input gear 314, and the rest of the fixed gear 3132 is a polished rod structure.

[0045] The ring gear 3133 is sleeved on the outside of the other end of the fixed gear 3132, and can be driven to rotate by the second driving member 312. Specifically, Figure 6 As shown, the driving assembly 31 of this embodiment can also include a second transmission gear 316, which is fixed to the output end of the second driving member 312, and the second transmission gear 316 is engaged with the outer teeth of the ring gear 3133. The second transmission gear 316 is driven to rotate by the second driving member 312, and the second transmission gear 316 can drive the ring gear 3133 to rotate.

[0046] The planetary gear 3134 is disposed between the fixed gear 3132 and the ring gear 3133 ( Figure 8 (as shown), and the planetary gears 3134 mesh with the internal teeth of both the fixed gear 3132 and the ring gear 3133, thereby enabling the planetary gears 3134 to orbit and rotate. The planetary gears 3134 are coaxially connected to the tool drive gear 3135 via a gear shaft 3137, enabling the planetary gears 3134 to drive the tool drive gear 3135 to rotate synchronously. The tool drive gear 3135 can mesh with the rack 3136 fixed to the cutting tool 32, driving the rack 3136 to move the cutting tool 32 radially, thereby adjusting the cutting depth.

[0047] In this embodiment, the revolution speed and rotation speed of the planetary gear 3134 are affected by the rotation speed of the ring gear 3133 and the fixed gear 3132 and the number of corresponding gear teeth. H The following relationship is satisfied between the rotation speed n1 and the number of gear teeth z1 of the ring gear 3133 and the rotation speed n3 and the gear diameter z3 of the fixed gear 3132:

[0048]

[0049]

[0050] When the rotational speed n1 and the number of gear teeth z1 of the above-mentioned ring gear 3133 and the rotational speed n3 and the gear diameter z3 of the fixed gear 3132 satisfy n1z1=n3z3, the planetary gear 3134 only revolves and does not rotate. The planetary gear 3134 drives the tool drive gear 3135 through the gear shaft 3137. Since the planetary gear 3134 does not rotate, the rack 3136 does not move in the radial direction, that is, the feed depth of the cutting tool 32 does not change. If n1z1≠n3z3, the planetary gear 3134 will rotate, and ultimately the feed depth of the cutting tool 32 will change to adjust to the required cutting depth. The purpose of regulating the revolution speed can also be achieved by adjusting the rotational speed of the first drive member 311 and the second drive member 312. The greater the revolution speed, the greater the rotational speed of the cutting tool 32, and the smoother the reaction force cone cut out.

[0051] By controlling the first driving member 311 and the second driving member 312 , the feed depth and the rotation speed of the cutting tool 32 can be controlled, thereby enabling the processing equipment of this embodiment to process reaction force cones with different requirements.

[0052] In this embodiment, Figure 2 and Figure 7 As shown, the transverse feed device 4 includes a support base 41, a transverse feed motor 42, a lead screw 43, a slider 44, and a slide rail 45, wherein the support base 41 is fixedly mounted on the support base 1, the transverse feed motor 42 is mounted on the support base 41, and the output end of the transverse feed motor 42 is connected to a lead screw 43, which is threadedly connected to the slider 44. The slider 44 slides on the slide rail 45, and the slide rail 45 is fixedly mounted on the support base 1. The cutting device 3 is fixedly connected to the slider 44 (for example, the cutting frame 30 of the cutting device 3 can be fixedly connected above the slider 44). The transverse feed motor 42 drives the lead screw 43 to rotate, which can cause the slider 44 to slide along the slide rail 45 and drive the cutting device 3 to slide in the axial direction of the cable 10, thereby enabling the cutting device 3 to achieve transverse feeding to complete the processing of the reaction force cone.

[0053] In this embodiment, by controlling the rotational speed of the lateral feed motor 42, the lateral feed speed of the cutting tool 32 can be adjusted, and further cooperating with the first drive member 311 and the second drive member 312 to control the feed depth and rotational speed of the cutting tool 32, the processing equipment of this embodiment can adapt to the processing requirements of cables 10 of different sizes, and cut reaction force cones of different shapes.

[0054] When using the cable main insulation layer reaction force cone processing equipment of this embodiment, the clamping device 2 is first adjusted according to the diameter of the cable 10 to clamp the cable 10 at both ends. The cable 10 is then passed through the cutting device 3. The cutting tool 32 of the cutting device 3 is then controlled to feed to a preset cutting depth. The cutting tool 32 is then controlled to rotate, and the cross-feed device 4 is simultaneously controlled to drive the cutting device 3 to move axially to achieve the purpose of processing the reaction force cone.

A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
