Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] Reference Figure 1 As shown, this embodiment provides a testing platform for steel structure bridges, including a first platform 1, a second platform 2 slidably connected inside the first platform 1, a bearing platform slidably connected to the top surfaces of the first platform 1 and the second platform 2, a bearing frame 6 installed on the top surface of the bearing platform, a hanging walking component installed at the end of the first platform 1, another hanging walking component installed at the end of the second platform 2, the first platform 1 and the second platform 2 are controlled to extend and retract by a telescopic component, the bearing platform and the first platform 1 are moved horizontally by a translation component, and a lifting component is installed on the bottom surface of the first platform 1.

[0018] This invention sets the first platform 1 and the second platform 2 to be mutually slidable, which allows the entire testing platform to adapt to steel structure bridges of different widths, thus broadening its application range. The bearing frame 6 is used for the standing of the testing personnel. During testing, it is attached to both sides of the steel structure bridge using the hanging walking component, facilitating the movement of the entire testing platform. The bearing platform is moved using the translation component, enabling lateral movement of the bridge. This allows for comprehensive testing of the steel structure bridge. The lifting component allows the entire testing platform to be easily raised and connected to the bridge. The multi-faceted structure of this invention greatly facilitates the testing of steel structure bridges.

[0019] The scheme is further optimized. The support platform includes a first movable platform 4. Several first sliders 401 are installed on the bottom surface of the first movable platform 4. The first sliders 401 are horizontally slidably connected to the top surface of the first platform 1. A second movable platform 5 is slidably connected inside the first movable platform 4. The sliding direction of the second movable platform 5 is the same as the sliding direction of the first platform 1. A second slider 501 is installed on the bottom surface of the second movable platform 5 away from the first movable platform 4. The second slider 501 is slidably connected to the top surface of the second platform 2. The support frame 6 is installed on the top surface of the first platform 1. The translation component is installed between the first movable platform 4 and the first platform 1.

[0020] The scheme is further optimized. The translation component includes a gear 402 rotatably connected to the first movable platform 4. The gear 402 meshes with the top surface of the first platform 1. The gear 402 shaft is connected to a drive motor, which is fixedly connected to the first movable platform 4.

[0021] By controlling the rotation of the drive motor (not shown in the figure), the gear 402 can be driven to rotate. The gear 402 is meshed with the first platform 1, so the first movable platform 4 can move on the top surface of the first platform 1. The second movable platform 5 is slidably engaged with the first movable platform 4, which can provide certain support for the first movable platform 4. In addition, with the arrangement of the first slider 401 and the second slider 501, the load-bearing frame 6 can have a larger range of motion, providing a wider field of view for the inspection of steel structure bridges.

[0022] The scheme is further optimized. The telescopic component includes a lead screw 3. The second platform 2 has a threaded hole 201 inside. The threaded hole 201 is threaded with the lead screw 3. The lead screw 3 is rotatably connected to the first platform 1. The lead screw 3 is shaft-connected to a lead screw motor 301, which is installed on the first platform 1.

[0023] Controlling the rotation of the lead screw motor 301 can drive the lead screw 3 to rotate, and the lead screw 3 can drive the second platform 2 to generate relative displacement, thereby achieving the purpose of controlling the relative width of the first platform 1 and the second platform 2. In addition, with the help of the attached walking component, the entire detection platform can adapt to bridges of different widths, making it more convenient in actual use.

[0024] The scheme is further optimized. The attached walking component includes a first telescopic rod 8 and a second telescopic rod 9. The first telescopic rod 8 is hinged to one end of the top surface of the first platform 1 and the second platform 2. The second telescopic rod 9 is hinged to the outside of the first platform 1 and the second platform 2 through the mounting plate 7. The movable end of the second telescopic rod 9 on one side is hinged to the side wall of the first telescopic rod 8. The movable end of the first telescopic rod 8 on one side is rotatably connected to a moving roller 11. The moving roller 11 is axled to a moving motor 10. The moving motor 10 is installed on the movable end of the first telescopic rod 8.

[0025] By controlling the extension and retraction of the second telescopic rod 9, the first telescopic rod 8 can be driven to swing at an angle. In conjunction with the moving roller 11, the moving roller 11 is hung on both sides of the steel structure bridge for easy inspection. The moving motor 10 can drive the moving roller 11 to move on the steel structure bridge, which facilitates the movement of the platform along the longitudinal direction of the bridge.

[0026] Further optimization of the design: the lifting component includes two hinge blocks 12, one of which is fixedly connected to the bottom surface of the first platform 1, and the other hinge block 12 is horizontally slidably connected to the bottom surface of the first platform 1. The two hinges are connected by a linkage telescopic component.

[0027] In a further optimized design, the linkage telescopic component includes several hinge rods 13 that are hinged together in the middle. The ends of adjacent hinge rods 13 are hinged to each other. The end of the top hinge rod 13 is hinged to the corresponding hinge block 12. The end of the bottom hinge rod 13 is hinged to a support plate 15. The fixed end of a lifting cylinder 14 is hinged to the support plate 15. The movable end of the lifting cylinder 14 is hinged to the middle of the bottommost hinge rod 13.

[0028] By controlling the extension and retraction of the lifting cylinder 14, multiple hinge rods 13 can be driven to work together to achieve the lifting and lowering of the entire platform, making it convenient to connect the testing platform to the steel structure bridge.
