At this time, detection block 1 9 will also move downward close to detection block 2 10 to adapt to wire ropes of different sizes. The starting motor 8 will drive the left roller 1 3 to rotate and make the left roller 2 4 rotate in the opposite direction. At the same time, the right roller 1 3 and roller 2 4 will also rotate in opposite directions to each other, so that the bottom shell 1 and rotating cover 2 can travel on the wire rope. When the bottom shell 1 and rotating cover 2 travel, they will explore the way through detection block 1 9 and detection block 2 10. If they encounter the stretched part of the wire rope, the part of the wire rope that is partially lifted, or the soil block, the detection block 1 9 and detection block 2 10 will resist the part and make the bottom shell 1 and rotating cover 2 stop traveling. The staff can check in time whether the cause is damage or blocked by other things.
