[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Referring to Figures 1 - 3 , an embodiment provided by the present invention: a bridge steel structure support device, including a support bottom plate 1 and a support plate 2. A first fixing plate 3 is fixedly connected to the top of the support plate 2. A first chute 4, a second chute 5 and a through groove 6 are provided in the first fixing plate 3. A motor 7 is fixedly connected to the top of the support plate 2. The output end of the motor 7 is fixedly connected to a threaded rod 8. A fixing block 9 is threadedly connected to the outside of the threaded rod 8. A second fixing plate 10 is fixedly connected to the side of the fixing block 9. The second fixing plate 10 slides in the through groove 6. A fixing frame 11 is fixedly connected to the second fixing plate 10. A gear 12 is rotatably connected in the fixing frame 11. A first slider 13 slides in the first chute 4. A second slider 14 slides in the second chute 5. A first rack 15 is fixedly connected to the first slider 13. A second rack 16 is fixedly connected to the second slider 14. Both the first rack 15 and the second rack 16 are engaged with the gear 12, so that when the gear 12 moves, it can drive the first rack 15 and the second rack 16 to move.

[0025] A third fixing plate 19 is fixedly connected to the top of the support bottom plate 1. A worm 20 is rotatably connected in the third fixing plate 19. A worm gear 22 is rotatably connected to the top of the support bottom plate 1. The worm gear 22 is engaged with the worm 20. A support column 23 is fixedly connected to the top of the worm gear 22. The support column 23 is fixedly connected to the support plate 2. One end of the worm 20 passes through the third fixing plate 19 and is fixedly connected to a crank 21. Connecting frames 17 are fixedly connected to the sides of both the first rack 15 and the second rack 16. A top plate 18 is fixedly connected to the connecting frame 17. The first rack 15 is parallel to the second rack 16. The first chute 4 is parallel to the second chute 5, so that the top plate 18 on the first rack 15 and the second rack 16 moves vertically up and down.

[0026] Working principle: Turning the crank 21 drives the worm 20 to rotate. The worm 20 drives the worm wheel 22 to rotate, and the worm wheel 22 drives the support column 23 to rotate, thereby driving the support plate 2 to rotate to adjust the horizontal angle when supporting the bridge steel structure. Starting the motor 7 drives the threaded rod 8 to rotate. The threaded rod 8 drives the fixed block 9 to rise. The fixed block 9 drives the second fixing plate 10 to slide in the through groove 6, thereby driving the fixed frame 11 to move upward. The fixed frame 11 drives the gear 12 to move upward. At the same time, the gear 12 drives the first rack 15 and the second rack 16 on both sides to rise. And the first slider 13 slides in the first chute 4, and the second slider 14 slides in the second chute 5. When the top plate 18 on the first slider 13 touches and supports the bridge steel structure upward, it stops moving. The gear 12 continues to rise along the first rack 15 and drives the second rack 16 to rise to support the bridge steel structure at another different plane, making it more convenient to support the steel structures not in the same plane, with high applicability and increased stability during support.
