The transmission line is divided into overhead transmission lines and cable lines. The overhead transmission line is composed of line towers, conductors, insulators, line hardware wires, tower foundations, grounding devices, etc. It is erected above the ground, and maintenance equipment is required when repairing the overhead transmission line.

For this reason, we propose a transmission line maintenance device. Utility Model Content

When adjusting, the screw handle 19 is turned to rotate the threaded rod 17, and the lifting block 18 is threadedly connected to the threaded rod 17 so that the lifting block 18 can be lifted and lowered in the groove on the support seat. After adjusting the position of the auxiliary wheel 7, the transmission line is located between the two positioning plates 15 in the U-shaped plate 13. In the initial state, the two positioning plates 15 are respectively located at the top and bottom of the inner wall of the U-shaped plate 13. During maintenance, the control system set in the device controls the rotating motor 9 to work, so that the driving wheel 8 rotates. With the cooperation of the auxiliary wheel 7 and the driving wheel 8, the device moves on the transmission line, and at the same time, the detection head on the X-ray flaw detector 4 5 is used to detect the transmission line. When a fault is detected, on the one hand, the fault can be marked with paint by the paint spraying mechanism 6. When the maintenance worker repairs the fault, the control system controls the electric telescopic rod 14 to work, so that the two positioning plates 15 in the U-shaped plates 13 at both ends of the support seat 1 respectively clamp and fix the transmission lines at both ends of the fault, so that the maintenance worker can perform maintenance work on the middle fault position. The spacing between the two braking mechanisms 3 can be adjusted according to the size of the fault area. During adjustment, the servo motor 12 is controlled to work to rotate the bidirectional screw 10. Through the threaded connection between the two sliders 11 and the two ends of the bidirectional screw 10, the two U-shaped plates 13 are simultaneously moved closer or farther away, thereby expanding the clamping position at both ends of the wire fault, which is convenient for maintenance personnel to inspect and repair the transmission line.
