The bypass wire clamp 12 is provided with a cylindrical groove for being attached to the main wire 37 and a spherical groove for being attached to the ball 39, and the spherical groove is matched with the position of the buckle 25.

The design meaning here is: when the ball head 39 of the bypass cable 40 enters the bypass wire clamp 12, the ball head 39 can squeeze the buckle 25 at the horizontal position, the limiting rotating shaft 26 starts to rotate, the tension spring 28 on the limiting rotating shaft 26 is pulled away, when the ball head 39 continues to lift until the ball head collides with the cushion pad 24, the limiting rotating shaft 26 is rotated by a certain angle (is propped by the limiting bolt), at the moment, the lower part of the limiting block 27 is sleeked to a small-diameter semicircle from a large-diameter semicircle under the action of the tension spring 28, the limiting rotating shaft 26 is propped by the limiting block 27 and cannot reversely rotate, namely, the buckle 25 is reversely locked, after the wire twisting wheel 17 stops driving, the ball head 39 of the bypass cable 40 can fall on the tail frame of the buckle 25, namely, the ball head 39 is positioned in the two bypass wire clamps 12 and cannot fall, and the purpose of self locking is achieved.

Fourth step, locking lap joint: the robot controls the driving tool 36 to enter the locking bell mouth 15 again, drives the two bypass wire clamps 12 to be continuously tightened, and locks the ball heads 39 of the main wire 37 and the bypass wire 40 together as shown in fig. 9; after the lapping is completed, the robot drives the grip tool 35 to be separated from the winch work tool 34, the winch work tool 34 is left on the lapped main line 37, and the robot continues the lapping operation of the two-phase and three-phase bypass cables, as in the above.

Fifth step, unlocking and recycling: when the bypass operation is lapped and the equipment between the lines is overhauled or replaced, the bypass tool and the bypass cable 40 on the main line 37 are required to be retracted, at the moment, the robot grabs the handle 33 on the winch tool 34 again through the gripper tool 35, the other mechanical arm drives the driving tool 36 to enter the locking horn mouth 15, the screw rod 1 is reversely driven, the bypass wire clamp 12 is opened for a certain distance, the four hooks are guaranteed to be still hung on the main line, the ball head 39 of the bypass cable 40 can slide from the buckle 25 in the bypass wire clamp 12, the bypass wire 12 is slowly descended in a non-free falling mode due to certain friction resistance of the wire twisting wheel 17, after the cable completely reaches the ground, the bypass wire clamp 12 is continuously driven to be opened to the maximum through the driving tool 36, the buckle 25 is triggered to be unlocked, and simultaneously the robot withdraws the winch tool 34 from the main line 37 through the gripper tool 35, so that the bypass operation is completed.
