Description

Technical Field

[0001] The present application relates to the technical field of frame stranding machines, and in particular to a roller-pressed wire stranding machine for high-voltage cable production. Background Art

[0002] The cable includes a core wire and a bundle of wires wrapped around the outer wall of the core wire. The outer side of the core wire can be wrapped with one or more layers of wire bundles. During the cable production process, it is often necessary to twist multiple thin bundles of wires into a thick cable.

[0003] In the existing high-voltage cable production roller bundle frame stranding machine, the cable is pulled out from one end of the reel during operation, and then multiple groups of cables are wound together through the guide block and rotated to complete the frame stranding work. During this process, the cable is pulled out from the reel and moves along the winding trajectory. In the existing technology, the cable will rub against the cable wound on the reel when it is pulled out, which may cause the insulation layer on the cable surface to be damaged, thereby affecting the insulation integrity of the high-voltage cable. Summary of the Invention

[0004] The present application proposes a roller-pressed wire frame stranding machine for high-voltage cable production, which has the advantage of reducing friction and is used to solve the problem of wear of the insulation layer caused by friction between the cable and the cable wound on the reel when the cable is pulled out of the reel.

The top of the sliding sleeve is fixedly connected with a second connecting plate, and the top of the second connecting plate is movably sleeved with a first guide wheel. The cable passes through the bottom of the first guide wheel, and the first guide wheel guides the cable and reduces friction between the cables.

[0011] Preferably, two groups of guide columns are provided on one side of the second connecting plate, and the two groups of guide columns are fixedly connected to the stranding cage. The middle of the outer surface of the guide column is fixedly connected to a second guide wheel, and the cable passes through the middle of the two groups of second guide wheels to ensure that its position is determined. The above structure can position the cable through the fixed block during operation to ensure that the cable passing-out position is determined.

[0012] Preferably, the buffer assembly includes a fixed block, which is fixedly connected to one side of the cage, and the outer surface of the fixed block is fixedly connected to a second support block, and the top of the second support block is fixedly connected to multiple groups of limit columns, and the outer sides of the multiple groups of limit columns are movably sleeved with sliding plates, and one side of the sliding plate is fixedly connected to one end of a second spring, and the other end of the second spring is fixedly connected to one side of the second support block.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The present invention starts the driving motor to drive the second rotating shaft to rotate, the rotation of the second rotating shaft drives the first bevel gear to rotate, the rotation of the first bevel gear drives the second bevel gear to rotate, the rotation of the second bevel gear drives the threaded rod to rotate, and after the threaded rod rotates, it pushes the threaded sleeve to move along the outer surface of the limiting shaft, and the movement of the limiting shaft drives the sliding sleeve, the second connecting plate and the first guide wheel to move, thereby guiding the cable, avoiding friction between cables during cable transportation, avoiding damage to the insulation layer on the cable surface, thereby improving the insulation integrity of the high-voltage cable, and avoiding damage to the safety and pressure resistance of the high-voltage cable.

[0019] 2. The present invention contacts the first spring through the sliding sleeve. When the pressure applied by the first spring to the sliding sleeve reaches a certain level, the sliding sleeve is in a fixed state, and the threaded rod continues to rotate, causing the threaded rod to displace. After the threaded rod is displaced, it drives the mating teeth to move and engages with the second bevel gear on the other side, thereby reversing the rotation direction of the threaded rod, thereby driving the sliding sleeve to move to the other side, so that the wire assembly perfectly adapts to the cable outlet, thereby reducing the sliding friction between the cable and the fixed plate, especially at high-speed outlet, significantly reducing surface wear, extending the service life of the cable insulation layer, and reducing maintenance frequency. At the same time, the cable can be guided when it moves to prevent the cable from deflecting.

[0020] 3. The present invention straightens the cable and presses the buffer wheel downward. The movement of the buffer wheel drives the first fixed column and the sliding plate downward. The downward movement of the sliding plate drives the second spring downward, thereby absorbing the inertia generated by the sudden stop of the frame stranding machine, avoiding the wear of the cable insulation layer or deformation of the conductor caused by the sudden stop, thereby reducing the defective rate.

[0033] See also Figure 1-8 The embodiment of the present invention provides a roller-pressed wire frame stranding machine for high-voltage cable production, comprising a base 1, a console 2 being fixedly connected to one side of the top of the base 1, a first support block 3 being fixedly connected to the other side of the top of the base 1, a first rotating shaft 4 being provided on one side of the first support block 3, and the first rotating shaft 4 being fixedly connected to the output end of a driving member inside the console 2;

[0034] A cage 5 is fixedly sleeved on the outer side of the first rotating shaft 4, and multiple groups of partition plates 6 are fixedly connected to the interior of the cage 5. Multiple groups of wire assemblies are arranged inside the cage 5;

[0035] A fixing block 25 is fixedly connected to one side of the stranding cage 5. A plurality of buffer assemblies are arranged inside the fixing block 25. The wire assemblies and the buffer assemblies are used to protect the cables to prevent the cables from being damaged during operation.

[0036] Among them, the wire assembly includes a driving motor 7, which is fixedly connected to one side of the partition plate 6, and the output end of the driving motor 7 is fixedly connected to the second rotating shaft 8. The outer side of one end of the second rotating shaft 8 is movably sleeved with a limiting sleeve 9, and one side of the limiting sleeve 9 abuts against the partition plate 6. The second rotating shaft 8 is rotatably connected to the partition plate 6, and one end of the second rotating shaft 8 is fixedly connected to a first bevel gear 10, and one side of the first bevel gear 10 abuts against the limiting sleeve 9. The limiting sleeve 9 limits the first bevel gear 10 to prevent the first bevel gear 10 from being dislocated and disengaged. Both sides of the first bevel gear 10 are threadedly connected to the second bevel gear 11, and the interiors of the two groups of second bevel gears 11 are fixedly connected to threaded rods 12, and the outer sides of the threaded rods 12 are threadedly connected to threaded sleeves 13;

[0037] The conductor assembly also includes a limit shaft 14, which is rotatably connected to the cage 5. A sliding sleeve 15 is movably sleeved on the outer side of the limit shaft 14. A first connecting plate 16 is fixedly connected to one side of the sliding sleeve 15. The first connecting plate 16 connects the sliding sleeve 15 and the threaded sleeve 13 to ensure that the sliding sleeve 15 and the threaded sleeve 13 can move synchronously. Fixed rings 17 are fixedly sleeved on both sides of the outer surface of the limit shaft 14. One side of each set of fixed rings 17 is fixedly connected to a first spring 18. After the sliding sleeve 15 moves, the two sets of first springs 18 will respectively abut against the two surfaces of the sliding sleeve 15.

[0038] The wire assembly also includes a matching tooth 19, which is fixedly sleeved on the outer side of the threaded rod 12, and the matching tooth 19 rotates synchronously with the second bevel gear 11. The matching tooth 19 can engage with the two sets of second bevel gears 11. The outer side of the threaded rod 12 is movably sleeved with a fixed plate 20, and the fixed plate 20 is fixedly connected to the partition plate 6. The top of the sliding sleeve 15 is fixedly connected to the second connecting plate 21, and the top of the second connecting plate 21 is movably sleeved with a first guide wheel 22. The cable passes through the bottom of the first guide wheel 22, and the first guide wheel 22 guides the cable and reduces the friction between the cables.

[0039] The second rotating shaft 8 is driven to rotate by the driving motor 7, and the rotation of the second rotating shaft 8 drives the first bevel gear 10 to rotate, and the rotation of the first bevel gear 10 drives the second bevel gear 11 to rotate, and the rotation of the second bevel gear 11 drives the threaded rod 12 to rotate. After the threaded rod 12 rotates, it pushes the threaded sleeve 13 to move along the outer surface of the limiting shaft 14. The movement of the limiting shaft 14 drives the sliding sleeve 15, the second connecting plate 21 and the first guide wheel 22 to move, thereby guiding the cable, avoiding friction between the cables during the cable transportation process, avoiding damage to the insulation layer on the cable surface, so as to improve the insulation integrity of the high-voltage cable and avoid damage to the safety and pressure resistance of the high-voltage cable.

[0040] Among them, two groups of guide columns 23 are provided on one side of the second connecting plate 21, and the two groups of guide columns 23 are fixedly connected to the cage 5. The middle of the outer surface of the guide column 23 is fixedly connected to the second guide wheel 24. The cable passes through the middle of the two groups of second guide wheels 24 to ensure that its position is determined. The cable is positioned by the fixed block 25 to ensure that the cable passing-out position is determined.

[0041] Among them, the buffer assembly includes a fixed block 25, which is fixedly connected to one side of the cage 5, and the outer surface of the interior of the fixed block 25 is fixedly connected to the second support block 26, and the top of the second support block 26 is fixedly connected to multiple groups of limiting columns 27, and the outer sides of the multiple groups of limiting columns 27 are movably sleeved with sliding plates 28, and one side of the sliding plate 28 is fixedly connected to one end of a second spring 29, and the other end of the second spring 29 is fixedly connected to one side of the second support block 26. The buffer assembly also includes two groups of first fixed columns 30, which are fixedly connected to the top of the sliding plate 28, and the two groups of first fixed columns 30 are symmetrically arranged. The interiors of the two groups of first fixed columns 30 are movably hinged with buffer wheels 31;

[0042] After the cable is straightened, the buffer wheel 31 is pressed downward, and the movement of the buffer wheel 31 drives the first fixed column 30 and the sliding plate 28 to move downward. The downward movement of the sliding plate 28 drives the second spring 29 to move downward, thereby absorbing the inertial impact caused by the emergency stop of the frame stranding machine, avoiding the wear of the cable insulation layer or deformation of the conductor caused by the emergency stop, thereby reducing the defective rate.

[0043] Among them, the two groups of second bevel gears 11 are respectively abutted against the fixed plate 20 and the cage 5. The fixed plate 20 and the cage 5 limit the second bevel gears 11 to prevent the position of the second bevel gears 11 from being displaced. The two second bevel gears 11 are abutted against each other through the fixed plate 20 and the first rotating shaft 4, and the second bevel gears 11 are limited to avoid displacement and affect the work.

[0044] Among them, the top tangent of the buffer wheel 31 and the tangent of one side of the second guide wheel 24 are on the same axis, and multiple groups of wire holes 32 are opened inside the cage 5. The multiple groups of wire holes 32 all correspond to the tangents of the buffer wheel 31, so that the top tangent of the buffer wheel 31 and the tangent of one side of the second guide wheel 24 are on the same axis, thereby avoiding unnecessary wear caused by cable bending.

[0045] Among them, multiple groups of wire drums 33 are fixedly connected to the interior of the stranding cage 5, and the bottom of the wire drum 33 is fixedly sleeved with a second fixing column 34. The wire drum 33 is fixed by the second fixing column 34 so that it is fixed inside the stranding cage 5 to complete the frame stranding.

[0046] Working principle:

[0047] During operation, the cable end is pulled out from one side of the second fixed column 34 and passes through the bottom of the first guide wheel 22, passes through the middle of the two sets of second guide wheels 24, and then contacts the top of the corresponding buffer wheel 31, and passes through one side of the fixed block 25. After the preparation work is completed, the driving member inside the console 2 starts to drive the first rotating shaft 4 to rotate, and the rotation of the first rotating shaft 4 drives the stranding cage 5 to rotate to twist the cable. At this time, the driving motor 7 starts to drive the second rotating shaft 8 to rotate, and the rotation of the second rotating shaft 8 drives the first bevel gear 10 to rotate, and the rotation of the first bevel gear 10 drives the second bevel gear 11 to rotate, and the rotation of the second bevel gear 11 drives the threaded rod 12 to rotate. After the threaded rod 12 rotates, it pushes the threaded sleeve 13 to move along the outer surface of the limiting shaft 14. The movement of the limiting shaft 14 drives the sliding sleeve 15, the second connecting plate 21 and the first guide wheel 22 to move, thereby guiding the cable, avoiding friction between the cables during the cable transportation process, avoiding damage to the insulation layer on the cable surface, so as to improve the insulation integrity of the high-voltage cable and avoid damage to the safety and pressure resistance of the high-voltage cable.

[0048] Since the cable will stay for a period of time on both sides due to overlapping during the process of the cable coming out of the reel, that is, when the cable comes out at the farthest end of the left and right ends of the moving reel, the sliding sleeve 15 will contact the first spring 18. When the pressure exerted by the first spring 18 on the sliding sleeve 15 reaches a certain level, the sliding sleeve 15 is in a fixed state, and the threaded rod 12 will continue to rotate, causing the threaded rod 12 to displace. After the threaded rod 12 is displaced, it drives the matching tooth 19 to move and engages with the second bevel gear 11 on the other side, thereby reversing the rotation direction of the threaded rod 12, thereby driving the sliding sleeve 15 to move to the other side, so that the wire assembly perfectly adapts to the cable outlet, thereby reducing the sliding friction between the cable and the fixed plate 20, especially when the cable is out at high speed, significantly reducing surface wear, extending the service life of the cable insulation layer, and reducing the maintenance frequency. At the same time, the cable can be guided when it moves to avoid cable deviation.

[0049] At the same time, when the frame stranding machine is working, an emergency situation requiring an emergency stop may occur. At this time, due to the emergency stop of the frame stranding machine, the cable will be subjected to greater pressure due to inertia, resulting in breaking, which may easily cause unnecessary losses. In the present application, after the cable is emergency stopped, the bottom of the cable will fit tightly with the buffer wheel 31. When the cable is subjected to excessive tension, the cable will straighten, thereby pressing the buffer wheel 31 to move downward. The movement of the buffer wheel 31 drives the first fixed column 30 and the sliding plate 28 to move downward. The downward movement of the sliding plate 28 drives the second spring 29 to move downward, thereby absorbing the inertia generated by the emergency stop of the frame stranding machine, avoiding wear of the cable insulation layer or deformation of the conductor caused by the emergency stop, and reducing the defective rate.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
