Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] As Figures 1-4 shown, a technical solution provided by the present invention:

[0023] A crane bearing frame includes a guiding frame 1. Bracket 2 is provided at the top ends on both sides of the guiding frame 1. A fixing block 3 is movably installed between the upper ends of the two brackets 2. A first shock-absorbing mechanism is provided between the fixing block 3 and the bracket 2. The first shock-absorbing mechanism includes a fixing frame 4 which is respectively arranged at the top end of the bracket 2 and on both sides of the fixing block 3. A spring damper 5 is movably installed between the fixing blocks 3 on both sides. A second shock-absorbing mechanism is provided between the fixing block 3 and the guiding frame 1. The two ends of the spring damper 5 are respectively provided with a first movable sleeve 6 and a second movable sleeve 7. The first movable sleeve 6 is movably connected to the fixing frame 4 outside the fixing block 3, and the second movable sleeve 7 is movably connected to the fixing frame 4 outside the bracket 2. The second shock-absorbing mechanism includes a movable rod 8 which is fixedly installed at the middle part of the bottom end of the fixing block 3. The movable rod 8 is movably sleeved with the middle part of the guiding frame 1. A friction sleeve 9 is arranged outside the lower end of the movable rod 8. A helical spring 13 is arranged between the fixing block 3 and the guiding frame 1 outside the movable rod 8.

[0024] In this embodiment, when lateral vibration occurs, the spring damper 5 can achieve the purpose of shock absorption and buffering at a horizontal angle. And a movable rod 8 is provided at the lower end of the fixing block 3. At the same time, a helical spring 13 is arranged between the fixing block 3 and the guiding frame 1 outside the movable rod 8. When vertical vibration occurs, the helical spring 13 can play a buffering role. Moreover, when the movable rod 8 moves up and down along the middle part of the guiding frame 1, the friction sleeve 9 outside the lower end of the movable rod 8 rubs against the inner wall of the guide groove in the middle part of the guiding frame 1, and the shock can be reduced through the frictional resistance.

[0025] As Figure 1 and Figure 4As shown, a threaded groove 10 is provided on the outer wall below the movable rod 8, and the inner wall of the friction sleeve 9 is threadedly connected to the threaded groove 10. Mounting brackets one 11 are symmetrically arranged on the outer sides of both sides of the guide frame 1, and a mounting bracket two 12 is provided in the middle of the top end of the fixed block 3;

[0026] In this embodiment, when the device is in use, first, the mounting bracket one 11 is fixed at a specified position on the crane through bolts, and then the camera is fixed on the mounting bracket two 12 at the top end of the fixed block 3 through bolts. Among them, support points are provided at both ends and the lower end of the fixed block 3. The structural stability can be improved through three-point support. In this way, when the camera works, the stability is higher.

[0027] Working principle: When the device is in use, first, the mounting bracket one 11 is fixed at a specified position on the crane through bolts, and then the camera is fixed on the mounting bracket two 12 at the top end of the fixed block 3 through bolts. Among them, support points are provided at both ends and the lower end of the fixed block 3. The structural stability can be improved through three-point support. In this way, when the camera works, the stability is higher. Since spring dampers 5 are provided between both ends of the fixed block 3 and the bracket 2, when lateral vibration occurs, the spring dampers 5 can achieve the purpose of shock absorption and buffering at a horizontal angle. And a movable rod 8 is provided at the lower end of the fixed block 3. At the same time, a spiral spring 13 is provided between the fixed block 3 and the guide frame 1 outside the movable rod 8. When vertical angle vibration occurs, the spiral spring 13 can achieve the purpose of buffering. Moreover, when the movable rod 8 moves up and down along the middle of the guide frame 1, the friction sleeve 9 outside the lower end of the movable rod 8 rubs against the inner wall of the guide groove in the middle of the guide frame 1, and the shock can be absorbed through the frictional resistance.
