[0023] When the tower crane hook 1 is in a vertical state, the spring 8 is also in a vertical state, and the metal ball 9 is located in the middle of the guideable metal ring 10. When the tower crane hook 1 is tilted at a small angle, the gravity of the metal ball 9 cannot cause the spring 8 to bend and deform, and the metal ball 9 and the metal ring 10 are still in a non-contact state. When the inclination angle of the tower crane hook 1 is large, the spring 8 will bend and deform under the action of the gravity of the metal ball 9, so that the metal ball 9 contacts the metal ring 10. When the tower crane hook 1 rotates, disturbs, and shakes violently, the spring 8 will also bend and deform under the action of the centrifugal force of the tower crane hook 1, so that the metal ball 9 contacts the metal ring 10, thereby connecting the circuit of the wireless signal transmitter 4. The wireless signal transmitter 4 quickly wirelessly sends out an alarm signal containing key data, and the wireless signal receiving alarm 5 sends out an audible and visual alarm in the corresponding tower crane hook operating room. The wireless receiving control host 6 receives and processes the alarm signal in the project monitoring duty room and sends the alarm information to the mobile terminal 7.

The tilt switch 3 and the wireless signal transmitter 4 are not directly mounted on the bottom plate of the box 12 to avoid the tilt switch 3 and the wireless signal transmitter 4 becoming inoperable after water enters the box. After the transmission antenna of the wireless signal transmitter 4 passes through the protective plate 15 and the right side wall of the box 12, its head end extends to the outside of the box 12. Extending the head end of the transmission antenna of the wireless signal transmitter 4 to the outside of the box 12 can prevent the wireless signal emitted by the wireless signal transmitter 4 from being blocked or shielded by the box 12. A protective plate 15 is provided so that even if rainwater penetrates into the right area of ​​the box body 12 from the transmission antenna opening on the side wall of the box body 12, it cannot enter the left area again through the protective plate 15, thereby ensuring that the left area is always a dry environment, thereby ensuring the service life of the tilt switch 3 and the wireless signal transmitter 4.

[0027] A mesh protection frame 16 is fixedly provided on the right outer wall of the box 12, and the head end of the transmission antenna is located inside the mesh protection frame 16 to prevent flying objects or hail from hitting the transmission antenna in severe weather environments, such as strong winds or hail. An opening for the transmission antenna to pass through is provided on the protection plate 15 and the right side wall of the box 12, and the opening around the transmission antenna is sealed with fillers to prevent rain, snow, mosquitoes, etc. from entering the box 12 through the opening.

[0028] The box 12 is installed on the top of the tower crane hook 1.
