[0029] A third motor 14 is fixedly mounted on the connecting arm 2 9, and an output end of the third motor 14 is fixedly connected to an active worm 2 15, and a driven worm gear 2 16 is meshedly connected to the active worm 2 15, and the driven worm gear 2 16 is fixedly connected to the zoom camera 17, and the zoom camera 17 is hinged to the connecting arm 2 9, and the end of the connecting seat 1 away from the base 2 is fixedly connected to the connecting rod 18, and the end of the connecting rod 18 away from the connecting seat 1 is fixedly connected to the fixing block 19, and a fastening bolt 20 is threadedly connected to the fixing block 19, and an arc-shaped protective cover 21 is fixedly connected to the base 2. The cover 21 covers the zoom camera 17, the active spur gear 4 and the driven spur gear 5 both rotate in the base 2, the rotating rod 6 passes through and rotates on the base 2, the fixed block 19 is U-shaped, the turntable 7 is located above the connecting arm 1 8, and the zoom camera 17 is located at the end of the connecting arm 2 9 away from the driven worm gear 1 13. The left and right fine-tuning function realized by the third motor 14 further improves the flexibility and accuracy of monitoring, allowing the operator to quickly adjust the monitoring angle according to actual needs and capture more key information, providing a strong guarantee for the safe lifting operation of the tower crane.
[0030] Working principle: In the easy-to-adjust tower crane lifting monitoring, the connecting base 1 serves as the basis of the entire monitoring device. It is tightly connected to the fixed structure on the tower crane through the connecting rod 18 and the fixing block 19. The fastening bolt 20 firmly fixes the fixing block 19 to the tower crane, providing a stable support for the monitoring device and effectively preventing shaking caused by factors such as vibration or wind. The arc-shaped protective cover 21 fixedly connected to the base 2 completely covers the zoom camera 17. This design is not only beautiful, but more importantly, it plays a role in dustproof, waterproof, and sunproof protection, effectively extending the service life of the zoom camera 17 and avoiding external factors such as dust and rain on the equipment. Damage caused, when it is necessary to adjust the position of the zoom camera 17 in the horizontal direction, start the first motor 3, the powerful power of the first motor 3 is transmitted to the active spur gear 4 through the output end, so that it starts to rotate, and the rotation of the rotating rod 6 drives the turntable 7 and the connecting arm 1 8 fixed thereon to perform horizontal circular motion. The connecting arm 1 8 is fixedly connected to the turntable 7, thereby achieving a smooth movement of the zoom camera 17 in the horizontal direction. The bottom of the connecting arm 1 8 is connected to the connecting arm 2 9 in an articulated manner, so that the connecting arm 2 9 can adjust the pitch angle relative to the connecting arm 1 8. On the connecting arm 1 8, the second motor 10 drives the turntable 7 through the transmission shaft 11 The active worm 12 rotates, and the active worm 12 is engaged with the driven worm gear 13. As the active worm 12 rotates, the driven worm gear 13 drives the connecting arm 29 to adjust the pitch angle in the vertical direction. Since the driven worm gear 13 is fixedly connected to the connecting arm 29, the connecting arm 29 can move accurately with the rotation of the driven worm gear 13, thereby driving the zoom camera 17 to adjust the pitch angle in the vertical direction. On the connecting arm 29, the active worm 15 connected to the output end of the third motor 14 interacts with the driven worm gear 2 16. The driven worm gear 2 16 is fixedly connected to the zoom camera 17, and the zoom camera 17 is fixedly connected to the zoom camera 17. It is connected to the connecting arm 2 9 in an articulated manner. This design allows the zoom camera 17 to be fine-tuned in the left and right directions. When the third motor 14 is started, the active worm gear 2 15 rotates, driving the driven worm gear 2 16 and the zoom camera 17 to rotate. By precisely controlling the rotation angle and speed of the third motor 14, the zoom camera 17 can be fine-tuned in the left and right directions to meet the needs of different monitoring angles. At the same time, the zoom camera 17 itself has a zoom function, and the user can adjust the distance of the shooting picture according to the monitoring needs. This function makes the zoom camera 17 more flexible and changeable during the monitoring process, and can capture more detailed information.
