[0028] Two semicircular ring members 1 are connected by a plurality of fasteners 2, and a slide groove 3 is provided on the outer wall of the semicircular ring member 1, and the slide grooves 3 corresponding to the two semicircular ring members 1 are connected;

[0029] A sliding support member 4, which is clamped on any of the semicircular ring members 1, and the sliding support member 4 is slidably connected in the slide groove 3, and two sets of sliding drive mechanisms 5 are provided on the sliding support member 4, and the sliding drive mechanisms 5 are against the inner wall of the slide groove 3;

[0030] A camera 6, which is located outside the semicircular ring member 1, and the camera 6 is hinged on the sliding support member 4;

[0031] A rotary motor 7, which is fixedly mounted on the sliding support 4, and the rotary motor 7 is connected to and drives the camera 6;

[0032] The sliding drive mechanism 5 includes a driving motor 51 and a rubber wheel 52. The driving motor 51 is fixedly mounted on the sliding support 4. The rubber wheel 52 is mounted on the output end of the driving motor 51, and the rubber wheel 52 abuts against the inner wall of the slide groove 3. The driving motor 51 rotates to drive the rubber wheel 52 to rotate. Under the friction between the rubber wheel 52 and the inner wall of the slide groove 3, the entire sliding support 4 is driven to slide along the slide groove 3, thereby realizing the multi-directional shooting adjustment of the camera angle 6.

[0033] The end surface of the sliding support member 4 is an arc surface, and the end surface of the sliding support member 4 abuts against the inner wall of the sliding groove 3, ensuring that the sliding support member 4 slides stably and smoothly;

[0034] The two opposite sides of the sliding support member 4 are provided with positioning grooves 8, and the bosses 9 at the two edges of the sliding groove 3 are respectively inserted into the two positioning grooves 8 to ensure that the sliding support member 4 slides stably and smoothly;

[0035] The inner wall of the semicircular ring member 1 is provided with two angle iron positioning members 10, so as to facilitate the quick fixing of the semicircular ring member 1 on the square tube support of the tower crane.

[0036] Working principle: First, select any semicircular ring member 1, align the positioning groove 8 on the sliding support member 4 with the boss 9, so that the two bosses 9 are inserted into the two positioning grooves 8. At this time, the end of the sliding support member 4 is against the inner wall of the slide groove 3, and the rubber wheel 52 is against the inner wall of the slide groove 3. Secondly, find the place where the tower crane needs to install the camera 6, and clamp the angle iron positioning member 10 of the semicircular ring member 1 at the corner of the square tube. Use a plurality of fasteners 2 to fix the two semicircular ring members 1 so that the corresponding slide grooves 3 of the two semicircular ring members 1 are connected, and the installation and fixation of the camera 6 can be completed. Then, the drive motor 51, the rotating motor 7 and the camera 6 are powered by cables. Finally, when the shooting angle of the camera 6 needs to be adjusted, the drive motor 51 rotates to drive the rubber wheel 52 to rotate. Under the friction between the rubber wheel 52 and the inner wall of the slide groove 3, the entire sliding support member 4 is driven to slide along the slide groove 3, and the rotating motor 7 drives the camera 6 to rotate, thereby realizing the multi-directional shooting adjustment of the camera angle.
