[0032] Next, with reference to the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] Refer to Figures 1 - 3 , an embodiment provided by the present utility model: A tower crane boom structure damage identification device includes a bracket 1, a middle ring 15, and a scanner 21. A protective frame 2 is slidably connected to the outside of the top end of the bracket 1. The protective frame 2 is sleeved outside the bracket 1. Two auxiliary wheels 3 are respectively rotatably connected to the front and rear adjacent sides of the protective frame 2. The auxiliary wheels 3 slide on the surfaces of the front and rear rods at the bottom end of the bracket 1 on the left and right sides of the inner bottom end of the protective frame 2. A protective cover 4 is fixedly connected to the top end of the protective frame 2. Two motors 5 are fixedly connected to the middle of the top end of the bracket 1. The protective cover 4 protects the motors 5, effectively preventing water and impact.

[0034] Reference Figure 3 、 Figure 4 On the front and rear sides of the bottom end of the bracket 1, the outer part of the auxiliary wheel 3 is slidably connected. The auxiliary wheel 3 slides on the rod surface of the bracket 1 to assist the protective frame 2 to slide stably. On the front and rear sides of the top end of the bracket 1, the outer part of the airbag 11 is slidably connected. The airbag 11 is closely attached to the outer part of the top end of the bracket 1 and can be resisted by the connection part of the rod at the top end of the bracket 1 to change its own diameter to adapt to the change at the connection of the diameters of the rods. The protective cover 4 is sleeved on the outside of the motor 5, and the protective cover 4 protects the protective cover 4 on the outside of the motor 5. The outer part of the connecting rod 6 is rotatably connected to the middle part of the top end of the protective frame 2. The connecting rod 6 penetrates through the middle part of the top end of the protective frame 2 to connect the motor 5. The driving end of the motor 5 is fixedly connected with the connecting rod 6, and the motor 5 drives the turntable 7 to rotate through the connecting rod 6.

[0035] The outer part of the connecting rod 6 is fixedly connected with a turntable 7. Three gas springs 8 are rotatably connected to the outer part of the turntable 7. One end of the gas spring 8 far from the turntable 7 is rotatably connected with a connecting block 9. One end of the three connecting blocks 9 far from the turntable 7 is fixedly connected with a soft ring 10. The outer part of the soft ring 10 is fixedly connected with an airbag 11. The outer part of the turntable 7 drives the soft ring 10 and the airbag 11 to rotate through the connection of the gas spring 8 and the connecting block 9. On the front and rear sides of the inside of the bracket 1, a plurality of connecting columns 12 are fixedly connected. In the middle positions of the front and rear sides of the inner side of the protective frame 2, four connecting columns 12 are fixed respectively.

[0036] Reference Figure 5 、 Figure 6 The bottom ends of the plurality of connecting columns 12 are fixedly connected with an outer ring 13. The connecting columns 12 are connected to the four corner positions of the outside of the outer ring 13. On the front and rear sides of the outside of the outer ring 13, which are close to each other, connecting rollers 14 are fixedly connected. The connecting rollers 14 are located on the inner side of the outside of the outer ring 13. A support assembly is arranged on the outside of the middle ring 15. The support assembly is for keeping the scanner 21 balanced.

[0037] The support assembly includes two holes 16, two holes 17, two limit columns 18, an inner ring 19 and a connecting shaft 20. The holes 16 are opened on the front and rear sides of the middle ring 15. The holes 17 are opened on the left and right sides of the middle ring 15. The holes 16 and the holes 17 are opened at the four corner positions of the middle ring 15. The outer part of the limit column 18 is rotatably connected to the inner wall of the hole 17. The middle parts of the two limit columns 18 are fixedly connected with an inner ring 19. The outside of the middle ring 15 is sleeved on the outside of the inner ring 19. The limit column 18 is restricted by the hole 17 of the middle ring 15, so that the inner ring 19 rotates at the middle position of the middle ring 15 through the limit column 18.

[0038] The outer part of the coupling shaft 20 is fixedly connected to the inner wall of the middle part of the inner ring 19. The outer ring 13 is sleeved on the outside of the middle ring 15. The widths of the outer ring 13 and the middle ring 15 are equal. The diameter of the middle ring 15 is smaller than that of the outer ring 13. The outer sides of the adjacent sides of the two connecting rollers 14 are rotatably connected to the inner wall of the hole 16. The bottom end of the coupling shaft 20 is fixedly connected to the middle part of the bottom end of the scanner 21. The scanner 21 will, due to its own gravity, keep the inner ring 19 connected by the coupling shaft 20 in a balanced state within the middle ring 15.

[0039] Working principle: When using this device, first, check whether the scanning lens of the scanner 21 is clear and whether it is connected to the external controller by telecommunications. After checking, the user can sleeve the protective frame 2 on the outside of the bracket 1, so that the auxiliary wheels 3 provided on the inner side of the bottom end of the protective frame 2 can slide along the surfaces of the left and right two rods at the bottom end of the bracket 1. Then, with the user starting the motor 5 to drive the turntable 7 to rotate through the connecting rod 6. After the turntable 7 rotates, it drives the soft ring 10 and the airbag 11 to rotate on the left and right sides of the top rod of the bracket 1 through the air spring 8 and the connecting block 9. During the sliding process of the protective frame 2, since the connecting end of the top rod of the bracket 1 is usually larger than the rod itself, when the airbag 11 slides to the connection part between the rods, the airbag 11 will be squeezed to drive the air spring 8 to expand and contract through the connecting block 9 and drive the turntable 7 to rotate, so that the diameter of the airbag 11 is reduced after being squeezed, realizing that the airbag 11 can smoothly pass through the connecting end of the rod, and enabling the identification device to slide stably without obstacles.

[0040] During the sliding process of the protective frame 2, because it slides closely against the surface of the rod of the bracket 1, and the rod surface of the bracket 1 is not all smooth, vibrations will occur when the device slides. At this time, the scanner 21 will, due to its own gravity, keep the inner ring 19 connected by the coupling shaft 20 in a balanced state within the middle ring 15. When the protective frame 2 vibrates and shakes, it will drive the middle ring 15 to rotate slightly through the connecting roller 14. And the vibration transmitted by the outer ring 13 to the middle ring 15 through the connecting roller 14 is gradually offset by its own gravity. Similarly, the vibration transmitted by the middle ring 15 to the inner ring 19 also gradually becomes smaller, effectively preventing the scanner 21 from shaking during the scanning and identification process, thereby reducing data errors.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
