Abstract
Description
Technical Field
[0001] This application relates to the field of cable manufacturing technology, and in particular to an insulation alignment device for parallel bundled overhead cables. Background Technology
[0002] Parallel bundled overhead cables, due to their compact symmetrical split structure, reduce cable inductance and reactance, increase inter-line dielectric constant, and increase capacitance, ultimately achieving the goal of expanding capacity and reducing losses. Because the cables are bundled together, their tensile strength is increased several times compared to single wires, reducing single-phase breakage accidents. Their splittable structure makes branch bridging easy and capacity-changing combinations convenient. This type of cable is simple to construct, saves labor and time, has low investment costs, and has significant long-term benefits.
[0003] Parallel bundled overhead cables are manufactured using a multi-hole extrusion die, where multiple conductors are simultaneously extruded for insulation. Unlike traditional extrusion dies, multi-hole extrusion dies cannot adjust the extrusion eccentricity using adjusting screws. The extrusion pressure of the plastic on each conductor within the die head is uneven, especially near the connecting ribs. Therefore, to ensure that the thinnest point of insulation meets standard requirements, the insulation extrusion thickness is typically increased.
[0004] The existing technical solutions mentioned above have the following drawbacks: increasing the insulation extrusion method will lead to waste of insulation material, resulting in increased manufacturing costs, and increasing the insulation thickness will lead to thicker and shorter connecting ribs, which is not convenient for cable construction. Utility Model Content
[0005] This application provides an insulation alignment device for parallel bundled overhead cables to facilitate insulation alignment during cable production and cable construction.
[0006] The above-mentioned technical objective of this application is achieved through the following technical solution:
[0007] A parallel bundled overhead cable insulation alignment device includes a base, on which a scissor lift is mounted. An installation platform is fixedly connected to the scissor lift. The installation platform has at least four installation slots spaced apart. Two of these slots contain embedded first limiting plates, while the remaining two slots contain embedded second and third limiting plates, respectively. Each of the first, second, and third limiting plates has a fixing bolt and a limiting bolt. One end of the fixing bolt passes through and is threaded into the installation platform, while the other end of the limiting bolt abuts against the installation platform. Each of the first, second, and third limiting plates has a limiting roller and a pressure roller, with at least two of each type spaced apart.
[0008] By adopting the above technical solution, the continuously set pressure rollers clamp the wire core vertically, which can fix the horizontal movement direction of the wire core during injection molding at a position level with the extrusion center of the injection mold. The multiple limiting rollers on the first limiting plate can bring multiple moving wire cores closer together in the horizontal direction. The multiple limiting rollers on the second and third limiting plates can cooperate with the pressure rollers to make multiple wire cores move in a straight line to the core hole of the injection mold during injection molding. By adjusting the height of the pressure rollers and limiting rollers that limit the movement direction of multiple wire cores by adjusting the limiting bolts, it is convenient for the staff to adjust the eccentricity of the extruded insulation, facilitate insulation adjustment during cable production, and facilitate cable construction.
[0009] Optionally, the first limiting plate, the second limiting plate, and the third limiting plate are all provided with limiting grooves. A slider is slidably arranged in the limiting groove. At least two sliders are arranged at intervals. The tops of the two sliders are respectively connected to the two limiting rollers. A rack is fixed to one side of the slider. A gear is rotatably arranged in the limiting groove. The gear meshes with the two racks. An adjusting screw is inserted in one of the racks. One end of the adjusting screw extends out of the first limiting plate, the second limiting plate, or the third limiting plate and is fixed to a handwheel.
[0010] By adopting the above technical solution, rotating the handwheel drives one rack to move within the limiting groove, while simultaneously driving the other rack to move via a gear. By driving both racks to move simultaneously via a gear, it is possible to ensure that the two sliders and the limiting rollers remain symmetrical with the top surface of the mounting platform when they move. This facilitates the adjustment of the spacing between the limiting rollers by the staff and ensures that the limiting rollers are symmetrically set.
[0011] Optionally, the peripheral walls of the pressure rollers on the second and third limiting plates are provided with positioning ring grooves.
[0012] By adopting the above technical solution, the wire core can be embedded and moved at a fixed interval, allowing multiple wire cores to move in a straight line to the core hole of the injection mold during injection molding. This facilitates the adjustment of the eccentricity of the extruded insulation by the staff, facilitates insulation adjustment during cable production, and facilitates cable construction.
[0013] Optionally, a positioning plate is fixedly connected to the third limiting plate, and a vertical plate is fixedly connected to the positioning plate, with at least two vertical plates spaced apart.
[0014] By adopting the above technical solution, the positioning plate makes it easier for staff to observe and measure the distance and height between the wire cores, and makes it easier for staff to observe the straight direction of the moving wire cores on the adjustment device when adjusting the adjustment device.
[0015] Optionally, the third limiting plate is provided with a positioning groove for the positioning plate to be embedded in.
[0016] By adopting the above technical solution, the positioning slot can facilitate the staff to replace positioning plates with different vertical plate spacings according to production needs, ensuring the accuracy of the installation position of the replaced vertical plates.
[0017] Optionally, the scissor lift is a scissor lift equipped with a locking mechanism.
[0018] By adopting the above technical solution, when the scissor lift stops lifting, the mechanical locking mechanism can prevent the scissor lift from lifting. The mechanical locking mechanism of the scissor lift can increase the safety and stability of the scissor lift when it is fixed at a certain height.
[0019] Optionally, a brush plate is installed on the first limiting plate.
[0020] By adopting the above technical solution, the wire cores entering the alignment device can be cleaned, reducing the damage to the wire cores or alignment device caused by impurities or large particles attached to the wire cores, and reducing the reduction in cable quality caused by impurities or large particles attached to the wire cores.
[0021] Optionally, a movable seat is fixedly connected to the base, and at least three movable seats are spaced apart. A movable screw is threaded through and connected to the movable seat, and a caster wheel is installed at one end of the movable screw.
[0022] By adopting the above technical solution, rotating the moving screw makes the universal wheel contact the ground and the base away from the ground, which makes it easy for the staff to push the adjustment device to move. After moving, rotating the moving screw until the base contacts the ground and the universal wheel away from the ground can stably place the adjustment device on the ground.
[0023] In summary, this application has the following technical effects:
[0024] 1. By setting up a scissor lift, mounting platform, limit rollers and pressure rollers, multiple wire cores are moved in a straight line to the core hole of the injection mold during injection molding. By adjusting the limit bolts, the pressure rollers and limit rollers that limit the movement direction of multiple wire cores are driven, which makes it convenient for workers to adjust the eccentricity of the extruded insulation, facilitate insulation adjustment during cable production, and facilitate cable construction.
[0025] 2. By setting up a positioning plate, it is convenient for staff to observe and measure the distance and height between the wire cores, and to observe the straight direction of the moving wire cores on the adjustment device when adjusting the adjustment device;
[0026] 3. By setting up a brush plate, the wire cores entering the alignment device can be cleaned, reducing the damage to the wire cores or alignment device caused by impurities or large particles attached to the wire cores, and reducing the reduction in cable quality caused by impurities or large particles attached to the wire cores.

Detailed Implementation
[0031] The present application will be further described in detail below with reference to the accompanying drawings.
[0032] This application discloses an insulation misalignment adjustment device for parallel bundled overhead cables, referring to... Figure 1 The adjustment device includes a base 1, which is a rectangular box with an open top. A scissor lift 11 is installed inside the base 1. In this embodiment, the scissor lift 11 is a scissor lift with a mechanical locking mechanism. When the scissor lift 11 stops lifting, the mechanical locking mechanism can prevent the scissor lift 11 from lifting. The top of the scissor lift 11 is fixed to a mounting platform 2 by bolts.
[0033] Reference Figure 1 and Figure 2 The mounting platform 2 has mounting slots 21, which are spaced out in six places along the top surface of the mounting platform 2. The first limiting plate 22 is embedded in the three mounting slots 21 near one edge of the mounting platform 2, and the third limiting plate 24 is embedded in the mounting slot 21 near the other edge of the mounting platform 2. The second limiting plate 23 is embedded in the two mounting slots 21 located between the first limiting plate 22 and the third limiting plate 24. Two second limiting plates 23 are spaced out. The bottom side wall of the base 1 is welded with a movable seat 12, which is spaced out in four places along the bottom of the base 1. One end of the movable seat 12 extends out of the base 1 and is threaded through by a movable screw 13. The movable screw 13 is threaded to the movable seat 12, and a caster wheel 14 is installed at the end of the movable screw 13 near the bottom surface of the base 1.
[0034] Reference Figure 2Each of the first limiting plate 22, the second limiting plate 23, and the third limiting plate 24 is provided with a fixing bolt 25 and a limiting bolt 26 at both ends along its length. Two fixing bolts 25 are spaced apart, and the limiting bolt 26 is located between the two fixing bolts 25. One end of the fixing bolt 25 passes through and is threaded to the first limiting plate 22, the second limiting plate 23, or the third limiting plate 24 to which it is connected, and the other end passes through and is threaded to the mounting platform 2. One end of the limiting bolt 26 passes through and is threaded to the first limiting plate 22, the second limiting plate 23, or the third limiting plate 24 to which it is connected, and the other end abuts against the top surface of the mounting platform 2.
[0035] Reference Figure 2 and Figure 3 Limiting grooves 31 are formed on the surfaces of the first limiting plate 22, the second limiting plate 23, and the third limiting plate 24. Sliding sliders 32 are slidably disposed within the limiting grooves 31. Two sliders 32 are spaced apart. Limiting rollers 3 are mounted on the top of each slider 32. The distance between the two limiting rollers 3 on the first limiting plate 22 is greater than the distance between the two limiting rollers 3 on the second limiting plate 23. The distance between the two limiting rollers 3 on the first limiting plate 22 decreases sequentially from away from the second limiting plate 23 to closer to the second limiting plate 23. A gear 33 is rotatably disposed within the limiting grooves 31, meshing with a rack 34. The rack 34 is configured with… There are two racks that are respectively attached to the sidewalls on both sides of the length direction of the limiting groove 31. One of the racks 34 is equipped with an adjusting screw 35. The adjusting screw 35 is set along the length direction of the limiting groove 31. One end of the adjusting screw 35 is located in the rack 34 and is threadedly connected to the rack 34. The other end extends out of the sidewall of the first limiting plate 22, the second limiting plate 23, or the third limiting plate 24 and is fixed to the handwheel 36 by bolts. The rack 34 connected to the adjusting screw 35 is welded to the slider 32 in the limiting groove 31 that is close to the handwheel 36. The rack 34 away from the adjusting screw 35 is welded to the slider 32 in the limiting groove 31 that is away from the handwheel 36.
[0036] Reference Figure 2 and Figure 3 The first limiting plate 22, the second limiting plate 23 and the third limiting plate 24 are all integrally formed with mounting blocks 4 at both ends of the plate surface along the length direction. The mounting blocks 4 connected to the same plate surface are rotatably connected with pressure rollers 41. Two pressure rollers 41 are arranged at intervals along the height direction of the mounting blocks 4. The peripheral wall of the pressure rollers 41 located on the second limiting plate 23 and the third limiting plate 24 is provided with positioning ring grooves 42 for cable embedding. Four positioning ring grooves 42 are arranged at intervals along the length direction of the pressure rollers 41.
[0037] Reference Figure 2A positioning groove 27 is provided on the surface of the third limiting plate 24 away from the second limiting plate 23. A positioning plate 5 is embedded in the positioning groove 27. The positioning plate 5 is fixed to the third limiting plate 24 by bolts. A vertical plate 51 is welded on the positioning plate 5. Two vertical plates 51 are arranged at intervals along the surface of the positioning plate 5.
[0038] Reference Figure 2 A brush plate 6 is connected to the first limiting plate 22 near the edge of the mounting platform 2 along its length. The surface of the brush plate 6 is rectangular and its two ends along its length are respectively fixed to the two mounting blocks 4 of the first limiting plate 22 facing each other by bolts. The brush plate 6 is located above the pressure roller 41 near the edge of the mounting platform 2 along its length, and the bristles of the brush plate 6 are located between the two pressure rollers 41.
[0039] When using this eccentricity adjustment device, the scissor lift 11 is controlled to raise and lower the mounting platform 2, facilitating the lifting and lowering of the mounting platform 2 by the operator. The mechanical locking mechanism of the scissor lift 11 increases the safety and stability of the scissor lift 11 when it is fixed at a certain height. By rotating the limit bolt 26, the height of the first limit plate 22, the second limit plate 23, and the third limit plate 24 can be adjusted to move the pressure roller 41 and the limit roller 3 to the horizontal height of the wire core and the core hole of the injection mold. This controls the eccentricity of the cable insulation, allowing one end of multiple wire cores to be pulled out from the cable reel and sequentially passed between the two pressure rollers 41 and the two limit rollers 3 on the first limit plate 22, the second limit plate 23, and the third limit plate 24. The wire core then enters the injection molding head for injection molding. Multiple continuously arranged pressure rollers 41 clamp the wire core vertically, which can fix the horizontal movement direction of the wire core during injection molding at a position level with the extrusion center of the injection mold. Multiple limiting rollers 3 on the first limiting plate 22 can bring multiple moving wire cores closer together in the horizontal direction. Multiple limiting rollers 3 on the second limiting plate 23 and the third limiting plate 24 can cooperate with the pressure rollers 41 to make the wire core move in a straight line into the core hole of the injection mold during injection molding. By adjusting the height of the pressure rollers 41 and limiting rollers 3 that limit the movement direction of multiple wire cores by adjusting the limiting bolts 26, it is convenient for the staff to adjust the eccentricity of the extruded insulation, facilitate insulation adjustment during cable production, and facilitate cable construction.
[0040] The distance between the two limiting rollers 3 on the first limiting plate 22 decreases sequentially from away from the second limiting plate 23 to close to the second limiting plate 23. This allows the distance between multiple wire cores to gradually decrease, reducing the unsmooth movement and damage of the wire cores when they are pulled, and ensuring the safety and stability of cable production.
[0041] The positioning groove 42 allows the wire core to be embedded and maintain a fixed spacing during movement, enabling multiple wire cores to move in a straight line to the core hole of the injection mold during injection molding. This facilitates the adjustment of the eccentricity of the extruded insulation by the staff, makes insulation adjustment during cable production easier, and facilitates cable construction.
[0042] When using this alignment device to produce cables of different sizes, the operator can rotate the handwheel 36 to move one of the racks 34 within the limiting groove 31, while simultaneously moving the other rack 34 via the gear 33. The simultaneous movement of both racks 34 via the gear 33 ensures that the two sliders 32 and the limiting rollers 3 remain symmetrical with the top surface of the mounting platform 2 during movement, facilitating the operator to adjust the spacing of the limiting rollers 3 and ensuring that the limiting rollers 3 are symmetrically set.
[0043] When moving the alignment device, rotate the moving screw 13 to make the caster wheel 14 contact the ground and the base 1 move away from the ground, so that the staff can push the alignment device to move. After moving, rotate the moving screw 13 until the base 1 contacts the ground and the caster wheel 14 moves away from the ground, so that the alignment device can be placed stably on the ground.
[0044] The positioning plate 5 facilitates workers' observation and measurement of the distance and height between wire cores, and also allows workers to observe the straight-line direction of the moving wire cores on the adjustment device when adjusting it. The positioning groove 27 allows workers to easily replace the positioning plates 5 with different spacings of the vertical plates 51 according to production needs, ensuring the accuracy of the installation position when replacing the vertical plates 51.
[0045] The brush plate 6 can clean the wire cores entering the alignment device, reducing the damage to the wire cores or alignment device caused by impurities or large particles attached to the wire cores, and reducing the reduction in cable quality caused by impurities or large particles attached to the wire cores.
[0046] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
