Referring to fig. 1 and 2, a device for balancing the tension and lifting functions of a ground wire and an optical cable according to a preferred embodiment of the present invention includes a base 10, a lifting screw 20 and a pulley 50.
With continued reference to fig. 1 and 2, one side of the base 10 is provided with a mounting bayonet 11 for clamping the base 10 to the tower, and in this case, the base 10 is formed as a clamp structure, and can be firmly clamped to the tower by the mounting bayonet 11. The base 10 is made of a high-strength aluminum alloy to secure strength and reduce weight as much as possible. According to the tower material (L shape or L shape) form of different towers, the mounting bayonets 11 can be slots formed from bottom to top or slots formed transversely, and of course, two mounting bayonets 11 can also be simultaneously arranged for selection according to specific situations.

In the present invention, since the ground wire and the OPGW optical cable of the overhead transmission line are aimed at, the ground wire or the optical cable mainly refers to the ground wire and the OPGW optical cable, and of course, other cables on the overhead transmission line can be lifted by the present invention.
In the preferred embodiment, the lifting screw 20 comprises a mounting sleeve 21, a threaded rod 22, a rotating part 24 and a rotating sleeve 25, wherein the mounting sleeve 21 is mounted on the base 10 and does not rotate with the base 10, the rotating sleeve 25 is rotatably mounted in the mounting sleeve 21 and sleeved on the threaded rod 22 in a threaded connection manner, the threaded rod 22 passes through the mounting sleeve 21, the pulley 50 is mounted at the bottom of the threaded rod 22, the rotating part 24 is fixedly mounted on the rotating sleeve 25 and extends along the radial direction of the rotating sleeve 25, the threaded rod 22 is provided with a limiting groove 26 extending along the axial direction, and the inner wall of the mounting sleeve 21 is provided with a limiting protrusion 27 positioned in the limiting groove 26. When the rotating part 24 is rotated, the rotating sleeve 25 rotates along with the rotating part, and the mounting sleeve 21 does not rotate, and the threaded rod 22 is matched with the limiting protrusion 27 through the limiting groove 26, so that when the rotating sleeve 25 rotates, the threaded rod 22 is correspondingly axially downward or upward, and when the threaded rod 22 is axially upward, the lifting is the lifting, and the lifting of the pulley 50 on the threaded rod 22 can be realized through the lifting of the threaded rod 22, so that the lifting of the ground wire or the optical cable is realized.
Further, in the preferred embodiment, a U-shaped placing bayonet 12 is provided at the side of the base 10, and a U-shaped locking bayonet 13 is provided at both sides of the upper end of the U-shaped placing bayonet 12 on the base 10.
