Wire lifting device in high-voltage transmission line erection

The utility model discloses a wire lifting device in high-voltage power transmission line erection, and the device achieves the lifting of connecting rods through an adjusting mechanism, enables a tooth block at the top end of the inner wall of a connecting groove to be separated from a tooth groove at the bottom end of the inner wall of a limiting groove, adjusts the distance between two connecting rods, and releases the connecting rods. A tooth block at the top end of the inner wall of the connecting groove is meshed with a tooth groove in the bottom end of the inner wall of the limiting groove, two protruding parts of a limiting cam are rotated to be in a vertical state, the upper protruding part of the limiting cam makes contact with the top end of the inner wall of the limiting groove, and therefore when the top end of the inner wall of the connecting groove makes close contact with the bottom end of the inner wall of the limiting groove, the limiting cam can rotate; and the limiting cam limits and fixes
