Description

Technical Field

[0001] This utility model relates to the field of wire pulling equipment technology, and in particular to an electromechanical power wire pulling device. Background Technology

[0002] Cable pulling equipment is a core device in electromechanical engineering used for pulling, guiding, and fixing cables, mainly used in the construction or maintenance of overhead power lines. Its core function is to replace manual pulling with mechanical power to achieve smooth cable laying, winding, or tensioning operations.

[0003] Currently, electric hoists are commonly used to pull cables. However, the pulling action of an electric hoist only applies to one end of the cable, which can easily lead to uneven stress on the cable. This can cause cable misalignment and twisting, and prolonged pulling can even cause wear on the cable sheath or breakage of the internal wires. In addition, in complex working environments, moving and fixing electric hoists is cumbersome, making it difficult to move them quickly or place them stably, thus affecting construction efficiency.

[0004] Therefore, this application proposes an electromechanical power cable pulling device. Utility Model Content

[0027] like Figure 3 As shown, there are two sets of first assembly plates 19, which are fixedly installed on both sides of the top of the bottom mounting base 18. The top of the first assembly plate 19 is wavy. The first drive roller 21 is movably installed in the middle of the two sets of first assembly plates 19 to provide power for pulling down the cable. Multiple sets of first driven rollers 20 are also movably installed between the two sets of first assembly plates 19. The first driven rollers 20 are the same shape and size as the first drive rollers 21 to assist the first drive rollers 21 in realizing the smooth transport of the cable.

[0028] like Figure 4 As shown, there are two sets of second assembly plates 24, which are fixedly installed on both sides of the bottom end of the top mounting base 23. The bottom end of the second assembly plate 24 is wavy. The second drive roller 26 is movably installed in the middle of the two sets of second assembly plates 24 to provide upward cable pulling power. Multiple sets of second driven rollers 25 are also movably installed between the two sets of second assembly plates 24. The second driven rollers 25 are the same shape and size as the second drive rollers 26, assisting the second drive rollers 26 in achieving smooth cable transport. The second right-angle motor 27 is fixedly installed on the outer wall of the second assembly plate 24 and the top mounting base 23 by screws. The output shaft of the second right-angle motor 27 is fixedly connected to the shaft of the second drive roller 26. The top of the top mounting base 23 is fixedly installed with a lifting plate 14, which drives the upward cable pulling unit 11 to adjust its height.

[0029] like Figure 2-4As shown, the drive assembly includes a first right-angle motor 22, a second right-angle motor 27, and a control box 17. The control box 17 is embedded in one side of the support plate 12. The control box 17 is electrically connected to the first right-angle motor 22 and the second right-angle motor 27.

[0030] like Figure 5 As shown, the position adjustment unit includes a lifting plate 14, a threaded rod 15, and a threaded sleeve 30. The threaded sleeve 30 is fixedly inserted through the top plate 13, and the threaded rod 15 is vertically inserted through the threaded sleeve 30. The threaded rod 15 and the threaded sleeve 30 are threadedly connected, and the lifting transmission is achieved through the threaded engagement.

Pull rods 16 are fixedly installed on both outer walls of the top plate 13.

[0031] The implementation principle of this utility model for an electromechanical power cable pulling device is as follows:

[0032] First, the device is moved to the working position where the cable needs to be pulled by the bottom mounting base 18. The cable is passed between the pull-down cable unit 10 and the pull-up cable unit 11. Then, the handwheel 32 is rotated by hand. The rotation of the handwheel 32 drives the threaded rod 15 to rotate. The threaded rod 15 is threadedly engaged with the threaded sleeve 30. The bottom end of the threaded rod 15 is movably mounted on the rectangular limit seat 31 through the bearing, so that the rotation of the threaded rod 15 is converted into the linear motion of the lifting plate 14 in the vertical direction. The lifting plate 14 slides up and down along the guide rod 29 in the lifting groove 28 until the second driven roller 25 and the second drive roller 26 contact the top of the cable.

[0033] Secondly, the first right-angle motor 22 and the second right-angle motor 27 are started by the program set in the control box 17. The pulse-type motion controller in the control box 17 precisely controls the first right-angle motor 22 and the second right-angle motor 27 to rotate synchronously in opposite directions, driving their respective first drive rollers 21 and second drive rollers 26 to rotate. Under the action of friction generated by the synchronous reverse rotation of the first drive roller 21 and the second drive roller 26, they move forward smoothly.

[0034] Finally, the first driven roller 20 and the first driving roller 21 are set to provide auxiliary support and guidance, ensuring that the cable remains stable during the pulling process and does not deviate or twist.

[0035] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
