[0028] Please refer to Figures 1-4 , an embodiment provided by the present utility model:

[0029] A bridge detection device with a protection structure, which includes:

[0030] Substrate 1, universal wheels 2 are symmetrically and fixedly installed on both sides of the bottom of substrate 1. Second support sleeves 17 are fixedly installed on both sides of the top of substrate 1. A telescopic plate 15 is slidably inserted into the top of the second support sleeve 17. A support plate 12 is fixedly installed on the top of the telescopic plate 15. A guardrail 9 is fixedly installed on the top of the support plate 12. A protective door 8 is arranged on the front of the guardrail 9. A first support sleeve 4 is fixedly installed between the two second support sleeves 17 on the top of substrate 1. A limiting plate 5 is slidably inserted into the top of the first support sleeve 4, and the top of the limiting plate 5 is fixedly connected to the bottom of the support plate 12;

[0031] Fixing holes 21 are formed above both sides of the first support sleeve 4. Fixing frames 26 are fixedly installed on both sides of the first support sleeve 4 above the fixing holes 21. Locking blocks 27 are slidably connected to the two fixing holes 21. Push plates 23 are fixedly installed on the opposite sides of the two locking blocks 27.

Electric telescopic rods 22 are fixedly installed below both sides of the first support sleeve 4 at the positions corresponding to the fixing holes 21, and the electric telescopic rods 22 correspond to the positions of the push plates 23. Springs 25 are sleeved on the outer walls of the slide bars 28;

[0032] A number of tooth grooves 16 are formed on both sides of the limiting plate 5, and the tooth grooves 16 are engaged with the locking blocks 27. A protective box 3 is fixedly installed on the top of the substrate 1. A driving mechanism is arranged inside the protective box 3. An escalator 6 is fixedly installed on the front of the support plate 12. A storage battery is arranged inside the protective box 3. A control switch is arranged on the guardrail 9. The arrangement of the protective box 3 can shield and protect the driving mechanism at the bottom of the substrate 1, improving the aesthetics and safety of the device.

[0033] A first motor 10 is fixedly installed above one side inside the guardrail 9, and the driving end of the first motor 10 penetrates through one side inside the guardrail 9 and extends to the outside of the guardrail 9. A winding disc 11 is fixedly installed at the driving end of the first motor 10. A pull rope 13 is arranged on the winding disc 11. One end of the pull rope 13 is fixedly installed with a hook 14.

[0034] In one embodiment, the driving mechanism includes a worm 18, and the worm 18 is rotatably installed inside the protective box 3. Both the first support sleeve 4 and the second support sleeve 17 penetrate through the inside of the protective box 3. The worm 18 penetrates through the first support sleeve 4 and the second support sleeve 17 respectively and is rotatably connected to the bearings installed on the first support sleeve 4 and the second support sleeve 17. A second motor 19 is fixedly installed on one side of the protective box 3, and the driving end of the second motor 19 penetrates through one side of the protective box 3 and extends into the inside of the protective box 3 and is fixedly connected to one end of the worm 18. Threaded rods 20 are rotatably installed at the bottoms inside both second support sleeves 17, and the telescopic plate 15 is threadedly connected to the threaded rods 20 through the threaded grooves opened at its bottom. Worms 24 are fixedly installed on the outer walls at the bottom ends of both threaded rods 20, and the worms 24 are meshed with the worm 18. The structure of the double threaded rods 20 is adopted to adjust the height of the device, making the operation of the device more stable and safe.

[0035] In one preferred embodiment, a protective cover is fixedly installed on one side of the protective box 3, and the second motor 19 is located inside the protective cover, providing protection for the second motor 19 to prevent dust, foreign objects, and other environmental factors from damaging the second motor 19.

[0036] In one embodiment, handles 7 are fixedly installed on both sides of the front of the guardrail 9 where the protective door 8 is located. The staff can easily open or close the protective door 8 through the handles 7 and safely enter the top of the support plate 12.

[0037] In one preferred embodiment, the opposite sides of both locking blocks 27 are inclined, and the locking blocks 27 are adapted to the tooth grooves 16, enabling the locking blocks 27 and the tooth grooves 16 to effectively cooperate. During the upward adjustment of the device, the locking blocks 27 can automatically engage with the tooth grooves 16 under the elastic action of the springs 25.

[0038] The working principle of the utility model is as follows: the electrical components appearing in the present application are all externally connected to the battery inside the protection box 3 and the control switch on the guardrail 9 when in use. The parts not involved in the device are the same as the prior art or can be implemented by the prior art. When in use, the device as a whole is first rolled in contact with the ground through the universal wheel 2 and pushed to the specified position. Then the staff can climb to the top of the support plate 12 with the help of the escalator 6, and control the second motor 19 to start working through the control switch. The driving end of the second motor 19 drives the worm 18 to rotate, and the worm 18 and the two worms are connected. The meshing of the two worm wheels 24 causes the two worm wheels 24 to rotate synchronously, and the rotation of the worm wheel 24 drives the threaded rod 20 to rotate. Through the threaded transmission of the threaded rod 20 and the telescopic plate 15, and the sliding relationship between the telescopic plate 15 and the second support sleeve 17, the two telescopic plates 15 are synchronously moved vertically, and the movement of the telescopic plate 15 drives the support plate 12 to move vertically, thereby achieving the effect of adjusting the height of the device. The support plate 12 will drive the limit plate 5 to move upward during the upward movement, and the upward movement of the limit plate 5 will interact with the inclined surface of the locking block 27, and the locking block 27 will be in the elasticity of the spring 25. Under the action of force, as the limit plate 5 rises, it continuously engages with the tooth groove 16 at the corresponding position. When the support plate 12 stays at a certain height, the locking block 27 is correspondingly engaged with the inside of the tooth groove 16 through the elastic action of the spring 25, and the locking block 27 limits the tooth groove 16 through the top plane, which will automatically lock the direction of the limit plate 5 moving vertically downward. In this way, even if the threaded transmission between the threaded rod 20 and the telescopic plate 15 fails during the use of the device at a specified height, the limit plate 5 can support the support plate 12 by relying on the positioning of the limit plate 5 by the locking block 27. The entire detection platform will not fall. The setting of this self-locking mechanism not only reduces the risk of equipment damage, but also significantly improves the safety of operators. When it is necessary to lower the height of the support plate 12, the staff can first control the electric telescopic rod 22 to start working. The driving end of the electric telescopic rod 22 pushes the push plate 23 to move. The push plate 23 drives the locking block 27 to disengage from the inside of the tooth groove 16 through the sliding rod 28. Under the action of the electric telescopic rod 22, the locking block 27 can release the limiting effect of the limiting plate 5 for a long time, so it does not affect the lowering of the height of the device.

[0039] During the process of inspecting a bridge, various tool materials may be required. When the device is operating at a specified height and lacks certain materials, the staff can directly control the driving end of the first motor 10 to drive the winding disc 11 to rotate. The rotation of the winding disc 11 can unload the pulling rope 13 from it, so that the hook 14 will descend until it reaches the ground. The staff on the ground can directly hang the required materials on the hook 14 and, by winding the pulling rope 13 through the winding disc 11, lift the hook 14, enabling the staff on the support plate 12 to easily obtain the lacking materials. Instead of lifting the entire device to retrieve materials, the staff can quickly obtain the required tools and materials through the operation of the hook 14 and the winding disc 11. This design greatly improves the flexibility and operation efficiency of the device and better meets the requirements in actual operations.

[0040] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
