When using power cables, they need to be laid accurately in the construction area using laying equipment. Power cable laying is a key link in the construction of power systems, and its construction quality and process directly affect the safe and stable operation of the power grid.

[0003] The Chinese utility model patent with authorization announcement number "CN219484037U" is specifically "a cable straightening device", which can use an active straightening wheel in conjunction with driven straightening wheels on the left and right sides to perform straightening operations on two cables, thereby improving the straightening work of batch cables.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] Example 1:

[0030] Reference Figure 1-4 This is the first embodiment of the present invention, which discloses an automatic straightening device for laying power cables, comprising:

[0031] The base 1 has brake wheels 2 that are evenly spaced and fixedly connected to its bottom. The brake wheels 2 use mechanical braking to push the automatic straightening device to the appropriate position when laying power cables, so as to straighten the power cables to be laid. After being pushed to the appropriate position, the braking effect of the brake wheels 2 is used to stabilize the position of the automatic straightening device.

[0032] The straightening mechanism 3 is located on the top of the base 1. The straightening mechanism 3 includes a servo motor 32. The servo motor 32 is located on the top of the base 1. The servo motor 32 is fixedly connected to a transmission rod 38 through an output shaft. An installation roller 34 is fixedly connected to the outside of the transmission rod 38. Two vertically distributed installation plates 37 are fixedly connected to the outside of the installation roller 34. A frame 31 is provided on the outside of the installation plate 37. A limit wheel 312 is fixedly connected to the inside of the frame 31. A movable pressure roller 314 is provided on the inside of the frame 31.

[0033] The two frames are set vertically in 31 directions to straighten the power cable from different directions, remove internal stress, and ensure that the power cable will not bend during installation.

[0034] The servo motor 32 drives the installation roller 34 to rotate through the output shaft, thereby adjusting the discharge direction of the straightened cable to meet the laying requirements of different directions during the laying of power cables.

[0035] Specifically, the transmission rod 38 has two symmetrically distributed support seats 33 connected to its outer side via bearings. The support seats 33 are fixedly connected to the top of the base 1, and the servo motor 32 is fixedly connected to the outer side of the support seats 33.

[0036] Two support seats 33 support the transmission rod 38 from both ends to ensure the stability of the mounting roller 34 when it rotates, and facilitate the smooth operation of the straightening mechanism 3 to straighten the power cable.

[0037] Specifically, the mounting plate 37 has a through mounting hole 36 on its outer side, a threaded rod 311 is fixedly connected to the outer side of the frame 31, the other end of the threaded rod 311 passes through the mounting hole 36, a nut is threadedly connected to the outer side of the threaded rod 311, a limiting hole 35 is opened on the outer side of the mounting plate 37, a limiting rod 310 is fixedly connected to the outer side of the frame 31, and the other end of the limiting rod 310 passes through the limiting hole 35.

[0038] The frame 31 can be installed and disassembled by the mounting hole 36, threaded rod 311 and nut, so that a new frame 31 can be installed as needed to facilitate the straightening of the laid power cable. In addition, when the limiting wheel 312 and pressure wheel 314 inside the frame 31 are damaged, they can be replaced in time to ensure the straightening effect of the power cable.

[0039] Specifically, the inner side of the frame 31 is provided with symmetrically distributed grooves 39, the outer side of the pressure roller 314 is fixedly connected to a slider 313, the slider 313 is slidably connected to the inner side of the corresponding groove 39, and the outer side of the pressure roller 314 is movably connected to a threaded rod 315 through a bearing, the other end of the threaded rod 315 passes through the frame 31 and is threadedly connected to the frame 31.

[0040] Rotating the threaded rod 315 can adjust the position of the pressure roller 314, thereby straightening power cables of different diameters, increasing the applicability of the straightening device and meeting different needs during power cable laying.

[0041] The cable to be straightened is passed through the two frames 31 and the drive mechanism 4 in sequence. The output direction of the power cable is adjusted according to the power cable construction site. During the adjustment, the servo motor 32 drives the installation roller 34 to rotate through the transmission rod 38. The rotation of the installation roller 34 adjusts the output direction of the straightened power cable through the installation plate 37 fixed on its outer side.

[0042] Rotate the threaded rod 315 to clamp the cable through the pressure roller 314. The power cable moves under the traction of the drive mechanism 4. When the cable moves, the two frames 31 in different directions straighten the bent cable and remove the internal stress. After straightening, the cable can enter the laying site for laying.

[0043] Example 2:

[0044] Reference Figure 1-4 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0045] The drive mechanism 4 is located on the outside of the mounting plate 37. The drive mechanism 4 includes a horizontal plate 41, which is fixedly connected to the outside of the mounting plate 37. An auxiliary roller frame 47 is fixedly connected to the outside of the horizontal plate 41, and a movable active roller frame 46 is provided on the outside of the horizontal plate 41.

[0046] With the cooperation of the active roller frame 46 and the auxiliary roller frame 47, the drive cable moves and is straightened by the straightening mechanism 3.

[0047] Specifically, a fixed base 45 is fixedly connected to the outer side of the horizontal plate 41, a cylinder 44 is fixedly connected to the inner side of the fixed base 45, an active roller frame 46 is fixedly connected to the telescopic end of the cylinder 44, a stepper motor 43 for driving the active roller to rotate is provided on the outer side of the active roller frame 46, and a through hole 42 is opened on the outer side of the horizontal plate 41.

[0048] The stepper motor 43 is equipped with an output shaft, and the stepper motor 43 is fixedly connected to the roller shaft of the drive roller through the output shaft.

[0049] The cylinder 44 can push the active roller frame 46 to move, thereby adjusting the distance between the active roller frame 46 and the auxiliary roller frame 47, so that it can drive cables of different diameters. The stepper motor 43 can drive the active roller inside the active roller frame 46 to rotate through the output shaft, which facilitates the movement of the cable.

[0050] After the cable passes between the active roller frame 46 and the auxiliary roller frame 47, the cylinder 44 pushes the active roller frame 46 to move and clamp the cable. When straightening the cable, the stepper motor 43 drives the active roller to rotate through the output shaft to transport the cable.

[0051] The remaining structure is the same as that in Example 1.

[0052] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
