In one embodiment of the present invention, as shown in fig. 1, the present invention provides a method for replacing a high voltage line insulator, comprising the steps of:
s1, connecting an electric wire tightener with a high-voltage line with an old insulator to be replaced, controlling a driving source of the electric wire tightener to rotate positively to move the high-voltage line to an area to be replaced, and acquiring force measurement data of a lifting transmission element in the electric wire tightener.
It should be noted that, in step S1, the electric tightener is used to move the high-voltage line requiring insulator replacement to the area to be replaced, and to obtain the force measurement data of the lifting transmission element in the electric tightener, so as to provide data for determining whether the high-voltage line reaches the replacement area.

It should be noted that, in step S2, it may be stated that the high-voltage line of the old insulator to be replaced has moved to the area to be replaced and the old insulator on the high-voltage line is to be replaced by the force measurement data being greater than the preset threshold value, and then the new insulator is moved to the area to be replaced by the lifting groove, and the old insulator on the high-voltage line may be replaced by the new insulator in the area to be replaced by a robot or manually, so as to replace the insulator on the high-voltage line. In this embodiment, in step S2, if the force measurement data is not greater than the preset threshold (i.e., it is determined that the old insulator to be replaced has not moved to the area to be replaced according to the force measurement data), it is indicated that the high-voltage line of the old insulator to be replaced has not moved to the area to be replaced, and the driving source of the electric wire tightener is controlled to continue to rotate forward until the old insulator to be replaced moves to the area to be replaced.
And S3, controlling the driving source of the electric wire tightener to reversely rotate, resetting the high-voltage line with the replaced insulator and disconnecting the electric wire tightener from the high-voltage line.

and S23, if not, adjusting the operation of the two conveying elements by controlling the execution element operated by each conveying element so as to enable the two conveying elements to operate synchronously.
It should be noted that, in the process of controlling the lifting groove to move to the area to be replaced, the position data of the two conveying elements in the lifting groove is obtained in real time, and whether the position data of the two conveying elements are the same or not is judged; if the position data of the two conveying elements are the same, indicating that the two conveying elements operate synchronously (such as synchronously lifting or lowering), the two conveying elements can be controlled to move the new insulator to the area to be replaced. If the position data of the two conveying elements are different, the two conveying elements do not synchronously operate, and the operating speed and the operating direction of the two conveying elements are adjusted by controlling the operating executing element of each conveying element until the two conveying elements synchronously operate.

The replacement method of the high-voltage line insulator moves the old insulator and the new insulator on the high-voltage line to the area to be replaced by mutually matching the electric wire tightener and the lifting groove, so that the replacement of the new insulator and the old insulator of the high-voltage line is realized; the replacement method of the high-voltage line insulator is simple in operation, does not need to manually operate the wire grip, is low in physical consumption, and solves the technical problems that operators need to consume large physical consumption and operation difficulty and long time in the existing operation mode of the wire grip.
