In this embodiment, the number of the driving motor 701 and the number of the capstan 703 are four, which corresponds to the number of the first wire 301, the output shaft of the driving motor 701 is fixedly connected to the driving rod 702, and the capstan 703 and the driving rod 702 are driven by a gear, so as to finally realize the wire pulling operation of the first wire 301. The driving motor 701 controls the corresponding capstan 703 to rotate forward or backward. The controller 6 analyzes the received signal to control the corresponding driving motor 701 to operate (forward rotation or reverse rotation) so as to extend or shorten the corresponding first wire 301. It should be noted that any other type of mechanical transmission structure may be used to drive the plurality of winches 703.

In some embodiments, please refer to fig. 8, the power transmission line iron tower reinforcing and adjusting device further includes an iron tower leg reinforcing structure 9, the iron tower leg reinforcing structure 9 includes an outer clamping plate 901, an inner clamping plate 902 and a connecting bolt 903, the outer clamping plate 901 and the inner clamping plate 902 are respectively located on the outer side and the inner side of the iron tower leg 8, and both ends of the outer clamping plate 901 and the inner clamping plate 902 are provided with mounting through holes for mounting the connecting bolt 903, and the mounting through holes are located on the outer side of the angle steel of the power transmission line iron tower. In this embodiment, the iron tower leg reinforcing structure 9 is used for reinforcing the iron tower leg 8, and also has the fixing function of the first stay wire 301 and the second stay wire 302. The tower legs 8 of the iron tower are composed of angle steel, the outer contour of the outer clamping plate 901 is a circular arc, and the inner contour is matched with the angle steel. The outer clamping plate 901 and the inner clamping plate 902 are respectively positioned at the inner side and the outer side of the angle steel, and the outer clamping plate 901 and the inner clamping plate 902 are fixedly connected through a connecting bolt 903. The hook 904 is welded on the outer wall of the outer clamping plate 901, the first pull wire 301 and the second pull wire 302 are both sleeved on the hook 904, the first pull wire 301 and the second pull wire 302 are effectively prevented from displacing under the action of tensile force, and the tensile force of the first pull wire 301 and the second pull wire 302 on the outer clamping plate 901 enables the iron tower leg reinforcing structure 9 not to loosen relative to the iron tower leg 8. The number of the inner clamping plates 902 is two, and the inner clamping plates are positioned at the upper end and the lower end of the outer clamping plate 901.

In some embodiments, the outer clamping plate 901 and the inner clamping plate 902 are both made of galvanized steel. In the embodiment, the galvanized steel sheet has good corrosion resistance and strong antirust capability.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
