Technical Field

[0001] The utility model relates to the technical field of cable straightening, in particular to a cable straightening device for overhead conductors. Background Art

[0002] During the production of overhead conductors, the aluminum alloy monofilaments within them must be inspected to ensure their performance and quality. Because overhead conductors undergo bending, folding, and curling during production, the finished product exhibits a spiral curl. This curling creates inconvenience for inspection, requiring the use of a cable straightening device to straighten the aluminum alloy monofilaments.

[0003] At present, the commonly used cable straightening device consists of two rows of transverse pressing wheels and two rows of longitudinal pressing wheels. The transverse pressing wheels are used to squeeze the cable transversely, and the longitudinal pressing wheels are used to squeeze the cable longitudinally to achieve the effect of straightening the cable.

[0004] To adapt the cable straightening device to cables of varying specifications, the spacing between the horizontal and vertical pressure rollers can be adjusted by the operator. When straightening round cables, the operator needs to adjust the spacing between the horizontal and vertical pressure rollers separately, making the cable straightening device adjustment process cumbersome.

At this time, the upper pressure wheel and the lower pressure wheel squeeze the round cable longitudinally, and the left pressure wheel and the right pressure wheel squeeze the round cable transversely, thereby achieving the effect of straightening the round cable. When straightening the round cable, it is only necessary to drive the sleeve to rotate, so that the upper pressure wheel, the lower pressure wheel, the left pressure wheel and the right pressure wheel can squeeze the cable, thereby achieving the effect of facilitating the straightening of the round cable and simplifying the adjustment process of the cable straightening device.

When the sleeve is rotated, the distance between the inner wall of the lower guide groove and the lower pressure wheel changes, which makes it easier for the lower guide groove to contact the lower pressure wheel on the lower guide rod against the round cable. When the sleeve is rotated, the distance between the inner wall of the left guide groove and the left pressure wheel changes, which makes it easier for the left guide groove to contact the left pressure wheel on the left guide rod against the round cable. When the sleeve is rotated, the distance between the inner wall of the right guide groove and the right pressure wheel changes, which makes it easier for the right guide groove to contact the right pressure wheel on the right guide rod against the round cable.

[0040] refer to Figures 1 to 7An upper roller 43 is rotatably mounted within the upper guide groove 21. An upper roller seat 431 is rotatably mounted on the upper roller 43 and welded to the top of the upper guide rod 41. An upper spring 42 is mounted on the upper guide rod 41. One end of the upper spring 42 is welded to the wheel frame 3, and the other end of the upper spring 42 is welded to the upper roller seat 431, so that the upper roller 43 abuts the inner wall of the upper guide groove 21. A lower roller 53 is rotatably mounted within the lower guide groove 22. A lower roller seat 531 is rotatably mounted on the lower roller 53 and welded to the bottom end of the lower guide rod 51. A lower spring 52 is mounted on the lower guide rod 51.

A left roller 63 is rotatably mounted within the left guide groove 23. A left wheel seat 631 is rotatably mounted on the left roller 63 and welded to the left end of the left guide rod 61. A left spring 62 is mounted on the left guide rod 61. One end of the left spring 62 is welded to the wheel frame 3, and the other end of the left spring 62 is welded to the left wheel seat 631, causing the left roller 63 to abut the inner wall of the left guide groove 23.

The upper spring 42 applies a force to the upper wheel seat 431 away from the wheel frame 3, and the lower spring 52 applies a force to the lower wheel seat 531 away from the wheel frame 3, thereby causing the upper pressure wheel 4 and the lower pressure wheel 5 to move away from each other, making it convenient for the round cable to pass between the upper pressure wheel 4 and the lower pressure wheel 5; the left spring 62 applies a force to the left wheel seat 631 away from the wheel frame 3, and the right spring 72 applies a force to the right wheel seat 731 away from the wheel frame 3, thereby causing the left pressure wheel 6 and the right pressure wheel 7 to move away from each other, making it convenient for the round cable to pass between the left pressure wheel 6 and the right pressure wheel 7. When the upper guide groove 21 rotates, the upper roller 43 rolls in the upper guide groove 21, and the upper roller 43 drives the upper pressure wheel 4 on the upper guide rod 41 to move in the height direction. When the lower guide groove 22 rotates, the lower roller 53 rolls in the lower guide groove 22, and the lower roller 53 drives the lower pressure wheel 5 on the lower guide rod 51 to move in the height direction. When the left guide groove 23 rotates, the left roller 63 rolls in the left guide groove 23, and at the same time, the left roller 63 drives the left pressure wheel 6 on the left guide rod 61 to move along the water direction. When the right guide groove 24 rotates, the right roller 73 rolls in the right guide groove 24, and at the same time, the right roller 73 drives the right pressure wheel 7 on the right guide rod 71 to move along the water direction.

[0041] After the round cable passes through the upper, lower, left, and right pressure rollers 4, 5, 6, and 7, the drive sleeve 2 rotates, driving the upper, lower, left, and right guide grooves 21, 22, 23, and 24. The rotation of the upper guide groove 21 causes the inner wall of the upper guide groove 21 to squeeze the upper roller 43. The upper roller 43 then moves the upper guide rod 41, causing the upper pressure roller 4 to approach the lower pressure roller 5. The rotation of the lower guide groove 22 causes the inner wall of the lower guide groove 22 to squeeze the lower roller 53. The lower roller 53 then moves the lower guide rod 51, causing the lower pressure roller 5 to approach the upper pressure roller 4. The left guide groove 23 rotates, causing the inner wall of the left guide groove 23 to squeeze the left roller 63. The left roller 63 drives the left guide rod 61 to move, causing the left pressure roller 6 to approach the right pressure roller 7. The right guide groove 24 rotates, causing the inner wall of the right guide groove 24 to squeeze the right roller 73. The right roller 73 drives the right guide rod 71 to move, causing the right pressure roller 7 to approach the left pressure roller 6. When the upper pressure roller 4 and the lower pressure roller 5 squeeze the round cable longitudinally, and the left pressure roller 6 and the right pressure roller 7 squeeze the round cable transversely, the cable is straightened. When straightening the round cable, the drive sleeve 2 rotates, causing the upper pressure roller 4, the lower pressure roller 5, the left pressure roller 6, and the right pressure roller 7 to synchronously approach the outer wall of the round cable, thereby simplifying the adjustment process of the cable straightening device.

[0042] Reference Figure 1 and Figure 8 A drive seat 83 is mounted on the base 1. A drive groove 84 is defined at the top of the drive seat 83.

A transmission gear 82 is mounted on the outer ring wall of the sleeve 2. The transmission gear 82 is an incomplete gear and meshes with the drive rack 81. The drive motor 8 drives the drive screw 86 to rotate, causing the drive block 85 to move along the drive groove 84. The movement of the drive block 85 drives the drive gear to move. The movement of the drive gear causes the transmission gear 82 to drive the sleeve 2 to rotate.

[0043] The working principle of the cable straightening device for overhead wires in the embodiment of the present application is as follows: after the round cable passes between the upper pressure wheel 4, the lower pressure wheel 5, the left pressure wheel 6, and the right pressure wheel 7, the drive sleeve 2 is rotated, which drives the upper guide groove 21, the lower guide groove 22, the left guide groove 23, and the right guide groove 24 to rotate. The upper guide groove 21 rotates so that the inner wall of the upper guide groove 21 squeezes the upper roller 43, and the upper roller 43 drives the upper guide rod 41 to move, causing the upper pressure wheel 4 to approach the lower pressure wheel 5; the lower guide groove 22 rotates so that the inner wall of the lower guide groove 22 squeezes the lower roller 53, and the lower roller 53 drives the lower guide rod 51 to move, causing the lower pressure wheel 5 to approach the upper pressure wheel 4. The left guide groove 23 rotates, causing the inner wall of the left guide groove 23 to squeeze the left roller 63. The left roller 63 drives the left guide rod 61 to move, causing the left pressure roller 6 to approach the right pressure roller 7. The right guide groove 24 rotates, causing the inner wall of the right guide groove 24 to squeeze the right roller 73. The right roller 73 drives the right guide rod 71 to move, causing the right pressure roller 7 to approach the left pressure roller 6. When the upper pressure roller 4 and the lower pressure roller 5 squeeze the round cable longitudinally, and the left pressure roller 6 and the right pressure roller 7 squeeze the round cable transversely, the cable is straightened. When straightening the round cable, the drive sleeve 2 rotates, causing the upper pressure roller 4, the lower pressure roller 5, the left pressure roller 6, and the right pressure roller 7 to synchronously approach the outer wall of the round cable, thereby simplifying the adjustment process of the cable straightening device.
