Description

Technical Field

[0001] This application relates to the field of high-voltage cable tapered cutting technology, and more specifically, to a high-voltage cable stress control tapered cutting tool with positioning and sealing functions. Background Technology

[0002] As society's reliance on electricity continues to increase and the need for urban beautification grows, the cable coverage rate in urban areas is rising year by year. As the difficulty of cable operation gradually increases, 10kV medium-voltage distribution network is the most common and widely used distribution network system. Due to the limitations of high-voltage cable manufacturing process, the maximum length of seamless cable manufacturing is 10km. It is necessary to process the joints of single cables and splice multiple cables together to achieve ultra-long-distance transmission.

[0003] At cable splices, due to the presence of two different insulating materials—the cable body insulation and the additional insulation—the electric field distribution differs from that of the cable body. This creates a potential difference, or axial field strength, between adjacent points on the same layer of insulation. The insulation near the conductor connection end is cut into a conical surface, known as a reactive force cone, and then additional insulation is wrapped around it. The ends of the additional insulation form stress cone surfaces, changing the potential distribution on the insulation surface and achieving a uniform electric field, thus ensuring the safety of the joint.

[0004] However, the current stress cone cutting of high-voltage cables is usually carried out manually, which is time-consuming and labor-intensive, and also results in low cone cutting efficiency and poor quality.

[0005] To address the aforementioned problems, this application provides a high-voltage cable stress control cone cutting tool with positioning and sealing functions. Summary of the Invention

[0006] This application provides a high-voltage cable stress control cone cutting tool with positioning and sealing functions, which adopts the following technical solution:

[0007] A high-voltage cable stress control cone cutting tool with positioning and sealing functions includes a base plate. A platform plate is positioned above the center of the base plate. A bidirectional cylinder is located at the center of the bottom of the platform plate, and support rods are fixedly connected to both sides of the bottom of the platform plate. The bottom of each support rod is fixedly mounted to the top of the base plate. Auxiliary components are provided at the drive ends of both sides of the bidirectional cylinder, with two sets of auxiliary components located on opposite sides of the platform plate. A rotating cylinder is positioned above the center of the platform plate, and a support seat is rotatably sleeved on the outer wall of the rotating cylinder. The support seat is fixedly connected to the platform plate. The top of the platform and both sides of the upper end of the support seat slide in contact with the limiting discs. The two limiting discs are fixedly sleeved on the outer wall of the rotating drum. A first gear is fixedly sleeved on the outer wall of one end of the rotating drum. A second gear meshes with the bottom end of the first gear. A motor is connected to one end face of the second gear through a rotating shaft. The motor is fixedly sleeved in the inner cavity of the lower middle part of the support seat. An adjusting cylinder is fixedly installed on the inner side wall of the middle part of the rotating drum. A connecting plate is fixedly installed on the drive end of the adjusting cylinder. A metal conical cutting tool is provided on the end face of the connecting plate facing away from the adjusting cylinder.

[0008] The above technical solution allows for the connection of the metal conical cutting tool and adjustment of the conical cutting position by adjusting the cylinder.

[0009] Furthermore, the metal conical cutting tool is located inside the rotating drum, and locking bolts are screwed onto all four corners between one side of the metal conical cutting tool and the connecting plate.

[0010] The above technical solution enables the locking bolt to fix the metal tapered cutting tool.

[0011] Furthermore, a fixing seat is fixedly sleeved on the outer wall of the middle part of the non-drive end of the bidirectional cylinder, and the fixing seat is fixedly installed at the middle position of the bottom of the platform plate.

[0012] Through the above technical solution, the mounting base can support and fix the bidirectional cylinder.

[0013] Furthermore, the inner cavities at the four corners of the platform plate are all perforated, and the four perforations are distributed on the outer side of the bottom end of the support.

[0014] Furthermore, a rectangular cover is provided on the top of the platform plate. The rectangular cover is located on the outside of the support base, and screws are fixedly installed at the four corners of the bottom of the rectangular cover. Each screw is movably inserted into the inner cavity of each through hole, and a nut is screwed onto the outer wall of the lower side of each screw. Each nut abuts against the bottom of the platform plate.

[0015] Through the above technical solution, the rectangular cover achieves a sealed protection for the top structure of the platform plate, thereby reducing the oxidation and corrosion problems of some metal structural components.

[0016] Furthermore, a sealing gasket is fixedly installed on the periphery of the bottom of the rectangular cover, and the bottom of the rectangular cover contacts the outer periphery of the top of the platform plate through the sealing gasket.

[0017] Through the above technical solution, the sealing gasket can improve the sealing contact function between the rectangular cover and the platform plate.

[0018] Furthermore, the auxiliary component includes a base, on both sides of the bottom of the base are fixedly mounted with rollers, and both rollers slide in contact with the top of the base plate. A clamping cylinder is fixedly connected to the top of the base, and three sets of clamping parts are evenly arranged on the circumference of the clamping cylinder.

[0019] Through the above technical solution, the rollers provide movable and stable support for the base.

[0020] Furthermore, the mounting component includes a pad fixedly installed on the outer surface of the middle part of the mounting cylinder. An adjusting screw is threaded through the connection between the pad and the inner cavity of the mounting cylinder. One end of the adjusting screw is fixedly connected to a rotating wheel, while the other end of the adjusting screw contacts a clamping strip. A limit rod is fixedly connected to one side of one end face of the clamping strip, and the limit rod is slidably sleeved through the inner cavity of the outer end of the mounting cylinder.

[0021] Furthermore, the mounting component also includes a T-shaped groove located at the center of the end face of the clamping bar facing the adjusting screw. A T-shaped shaft is rotatably sleeved on the inner wall of the T-shaped groove, and the T-shaped shaft is fixedly installed at the center of the end of the adjusting screw facing away from the rotating wheel.

[0022] Furthermore, the clamping strip is located inside the clamping cylinder, and multiple arc-shaped grooves are linearly and uniformly formed on one end face of the clamping strip facing away from the T-shaped groove.

[0023] Through the above technical solution, the setting of three sets of clamping parts on the clamping cylinder can effectively ensure the stable pressure-resistant positioning function of the high-voltage cable running through its inner side.

[0024] In summary, this application includes the following beneficial technical effects:

[0025] (1) This application achieves stable support of the structure above it by setting the base plate, and at the same time, by using the set platform plate, bidirectional cylinder, support rod, rotating cylinder, support seat, limit plate, first gear, second gear, motor, adjusting cylinder, connecting plate, metal conical cutting tool and two sets of auxiliary components, it can realize the automatic conical cutting of the end of the high voltage cable under the stable clamping action, and overcome the time-consuming and laborious manual operation in the present, while improving the efficiency and quality of conical cutting;

Both limiting discs 8 are fixedly sleeved on the outer wall of the rotating drum 6. A first gear 9 is fixedly sleeved on the outer wall of one end of the rotating drum 6. A second gear 10 is meshed at the bottom end of the first gear 9. A motor 11 is connected to one end face of the second gear 10 through a rotating shaft.

A connecting plate 13 is fixedly installed on the drive end of the adjusting cylinder 12. A metal conical cutting tool 14 is provided on the end face of the connecting plate 13 facing away from the adjusting cylinder 12.

[0042] The metal conical cutter 14 is located inside the rotating drum 6, and locking bolts 15 are screwed together at the four corners between one side of the metal conical cutter 14 and the connecting plate 13. With the setting of the four locking bolts 15, the metal conical cutter 14 can be positioned and assembled on one side of the connecting plate 13, and it is also convenient to disassemble, maintain or replace the metal conical cutter 14. A fixing seat 16 is fixedly sleeved on the outer wall of the middle part of the non-drive end of the bidirectional cylinder 3. The fixing seat 16 is fixedly installed at the middle position of the bottom of the platform plate 2.

[0043] The inner cavities at the four corners of the platform plate 2 are all perforated with through holes 17, and the four through holes 17 are distributed on the outer side of the bottom end of the support seat 7. A rectangular cover 18 is provided on the top of the platform plate 2. The rectangular cover 18 is located on the outer side of the support seat 7, and screw rods 19 are fixedly installed at the four corners of the bottom of the rectangular cover 18. Each screw rod 19 is movably inserted into the inner cavity of each through hole 17, and a nut 20 is screwed onto the outer wall of the lower side of each screw rod 19. Each nut 20 abuts against the bottom of the platform plate 2. A sealing gasket is fixedly installed on the peripheral wall of the bottom of the rectangular cover 18, and the bottom of the rectangular cover 18 contacts the outer periphery of the top of the platform plate 2 through the sealing gasket.

[0044] Please see Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7The auxiliary component 5 includes a base 51, with rollers 52 fixedly installed on both sides of the bottom of the base 51, and both rollers 52 slidingly contacting the top of the base plate 1. A clamping cylinder 53 is fixedly connected to the top of the base 51, and three sets of clamping parts are evenly arranged on the circumference of the clamping cylinder 53. The clamping parts include a pad 54 fixedly installed on the outer surface of the middle part of the clamping cylinder 53. An adjusting screw 55 is screwed through the connection between the pad 54 and the inner cavity of the clamping cylinder 53. One end of the adjusting screw 55 is fixedly connected to a rotating wheel 56, and the other end of the adjusting screw 55 contacts a pressing strip 57. A limit rod 58 is fixedly connected to one side of one end face of the pressing strip 57, and the limit rod 58 is slidably sleeved in the inner cavity of the outer end of the clamping cylinder 53.

[0045] The mounting component also includes a T-shaped groove 510 located at the center of the end face of the clamping bar 57 facing the adjusting screw 55. A T-shaped shaft 59 is rotatably sleeved on the inner wall of the T-shaped groove 510, and the T-shaped shaft 59 is fixedly installed at the center of the end of the adjusting screw 55 facing away from the rotating wheel 56. The clamping bar 57 is located inside the mounting cylinder 53, and multiple arc-shaped grooves are linearly and uniformly formed on the end face of the clamping bar 57 facing away from the T-shaped groove 510. With multiple arc-shaped grooves on the end face of the clamping bar 57, the contact roughness with the outer surface of the high-voltage cable can be improved, thereby improving the anti-slip effect under the pressure and positioning state of the outer surface of the high-voltage cable.

[0046] The implementation principle of this application embodiment is as follows: When in use, the whole is in a fully assembled state. By removing each nut part 20, the rectangular cover 18 can be removed and placed aside. One end of the high-voltage cable to be processed passes through the inner side of the two clamping cylinders 53 in sequence, and at the same time passes through the inner side of the rotating cylinder 6. Then, by rotating the adjusting screw 55 through each rotating wheel 56, the clamping strip 57 moves inside the clamping cylinder 53 and achieves the abutment and clamping effect on the outer surface of the high-voltage cable, thereby realizing the positioning operation of the high-voltage cable. Before positioning, the position to be tapered at the end of the high-voltage cable needs to be locked at the corresponding point of the metal tapered cutting tool 14 inside the rotating cylinder 6.

[0047] Then, the motor 11 is started, causing the second gear 10 to rotate. Utilizing the meshing state of the second gear 10 and the first gear 9, and the limiting rotation state of the support seat 7 and the two limiting discs 8 on the rotating drum 6, the rotating drum 6 is indirectly rotated. In conjunction with the connecting drive of the adjusting cylinder 12 to the metal conical cutting tool 14, a circumferential conical cutting operation is performed on the insulation sheath of the high-voltage cable, and the insulation sheath on both sides of the conical cutting position of the metal conical cutting tool 14 is separated. Then, while controlling the start of the bidirectional cylinder 3, the two bases 51 and the clamping cylinder 53 are pushed to move in opposite directions, and the cable insulation sheath cut out by the conical cutting is separated from the metal conductor. During this process, each roller 52 supports the base 51 and moves and rolls on the base plate 1.

[0048] After the entire process is completed and the device is in a static state, the rectangular cover 18 needs to be reinstalled on the top of the platform plate 2, so that each screw 19 is inserted into the through hole 17, and the screw 19 is locked by each nut 20. This achieves a sealed protection effect on the metal structural components such as the metal tapered cutting tool 14, the first gear 9, the second gear 10, and the motor 11 covered inside the rectangular cover 18, thereby effectively reducing the oxidation and corrosion problems they cause.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
