The signal emitted by the photoelectric transmitter is received by the receiver directly below. When the feedback plate moves, the receiver is offset and cannot receive the signal emitted by the photoelectric transmitter. At this time, the receiver transmits the data to the external terminal, and the external terminal receives the data, thereby facilitating timely reflection of the tower displacement.

While the tower is fixed, through the photoelectric transmitter and reflector in the monitoring mechanism, when the feedback abutment plate is translated, the receiver transmits data to the external terminal, and the external terminal receives the data, thereby facilitating timely reflection of the displacement of the tower, thereby completing real-time monitoring of the fixing state of the tower, so that personnel can understand it in time.

The contact switch transmits the signal to the external terminal; Step 3: The peripheral terminal receives the signal and controls the drive motor 409 to start, and the drive motor 409 drives the transmission shaft 4010 to rotate, driving the gear 4011 to rotate. Due to the meshing connection between the gear ring 401 and the gear 4011, the gear ring 401 rotates with the gear 4011. Under the restriction of the track plate 402 and the track slot 403, the linkage round rod 404 moves toward the center of the gear ring 401 in the track slot 403, thereby driving the connecting plate 205 and the inner plate 201 to move toward the tower 10, until the arc surface of the inner wall of the inner plate 201 contacts the tower 10, and the tower 10 is pressed tightly, thereby completing the fixing effect of the fixing device on the tower 10; Step 4: The curved surface of the inner wall of the feedback plate 302 is pressed against the tower 10 as the curved surface of the inner wall of the inner plate 201 is pressed against the tower 10. During the movement of the installation ship, if the tower 10 translates left and right, the feedback plate 302 will translate along with the tower 10 under the action of friction. The signal emitted by the photoelectric transmitter 304 is received by the receiver 306 directly below. When the feedback plate 302 translates, the receiver 306 is offset and cannot receive the signal emitted by the photoelectric transmitter 304. At this time, the receiver 306 transmits the data to the external terminal, and the external terminal receives the data, thereby facilitating timely reflection of the displacement of the tower 10.
