[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] like Figure 1-7 As shown, this utility model provides an auxiliary support structure for a large-span prestressed beam, including a support mechanism 1 connected to two columns 5. A crossbeam 6 is installed on the columns 5. The support mechanism 1 includes a mounting plate 11 and two steel cables 12. The steel cables 12 are connected to the two columns 5. Support components 2 are symmetrically distributed on both sides of the top of the mounting plate 11. Support plates 21 are installed on the top of the four support components 2, and the support plates 21 are in contact with the ground of the crossbeam 6. The support components 2 include rods 22, and connecting rods 24 are movably inserted into the rods 22. The bottom end of the rod 22 is rotatably connected to the mounting plate 11, and the top end of the connecting rod 24 is rotatably connected to the support plate 21. A circular groove 23 is provided inside the rod 22, and a pressure plate 25 is fixedly provided at the bottom end of the connecting rod 24. Both the pressure plate 25 and the connecting rod 24 are movably inserted into the circular groove 23. A compression spring 26 is installed in the circular groove 23. Two steel cables 12 are installed at the bottom end of the mounting plate 11. Under the action of the compression spring 26, the connecting rod 24 has an upward thrust, which enables the dynamic adjustment of the crossbeam 6 and more precise load distribution, effectively reducing vibration and deformation, and improving the stability and safety of the structure.

[0023] A rotating shaft 3 is rotatably inserted inside the mounting plate 11. A rotating plate 31 is fixedly installed on the outside of the rotating shaft 3. Fixed rods 32 are fixed at both ends of the rotating plate 31. A guide plate 33 is symmetrically distributed and slides at the bottom of the mounting plate 11. Two steel cables 12 are movably inserted into the guide plate 33. A connecting plate 34 is fixed at the top of the guide plate 33. A square groove 35 is opened in the connecting plate 34. The two fixed rods 32 are movably inserted into the two square grooves 35 respectively.

[0024] By adopting the above technical solution, the guide plate 33 moves in opposite directions to tighten and contract the two steel cables 12, thereby increasing the tension of the steel cables 12 on the crossbeam 6 and improving the stability of the crossbeam 6.

[0025] A friction pad 27 is fixedly provided at the top of the support plate 21.

[0026] By adopting the above technical solution, the friction pad 27 can increase the friction between the support plate 21 and the crossbeam 6.

[0027] The mounting plate 11 has an array of fixing blocks 37 fixed at its bottom end. A guide ring 38 is fixed at the bottom end of the fixing block 37, and the steel cable 12 is movably inserted into the guide ring 38.

[0028] By adopting the above technical solution, the guide ring 38 can guide the steel cable 12.

[0029] The guide plate 33 has grooves 36 on opposite sides, and two steel cables 12 are respectively inserted into the grooves 36.

[0030] By adopting the above technical solution, the groove 36 can be used to lock and limit the steel cable 12.

[0031] Mounting plate 11 is fixedly provided with protective box 4, which can protect the equipment. Rotary shaft 3 is rotatably inserted into protective box 4, and worm gear 41 is rotatably inserted into protective box 4. Worm wheel 42 is fixedly provided on the outside of rotating shaft 3, and worm gear 41 and worm wheel 42 mesh with each other.

[0032] By adopting the above technical solution, the worm gear 41 rotates, driving the rotating shaft 3 to rotate.

[0033] A motor 43 is fixedly installed inside the protective box 4. The end of the output shaft of the motor 43 is inserted into the protective box 4 and fixedly connected to the worm gear 41.

[0034] By adopting the above technical solution, the end of the output shaft of the motor 43 rotates, driving the worm gear 41 to rotate, thereby providing power output.

[0035] The bottom of the mounting plate 11 is fixed with symmetrically distributed auxiliary rods 39, both of which are movably inserted into the connecting plate 34.

[0036] By adopting the above technical solution, the auxiliary rod 39 can assist the mounting connecting plate 34 in lateral movement.

[0037] Working principle: First, connect both ends of the steel cable 12 to the column 5. Then, place the support plate 21 against the bottom of the crossbeam 6. Under the action of the compression spring 26, the connecting rod 24 will have an upward thrust, which in turn causes the support plate 21 to apply an upward thrust to the crossbeam 6. This allows for dynamic adjustment of the crossbeam 6 and more precise load distribution, effectively reducing vibration and deformation, and improving the stability and safety of the structure. When it is necessary to adjust the tension of the steel cable 12, the motor 43 is started, causing the output shaft of the motor 43 to rotate and drive... The worm gear 41 rotates, which drives the meshing worm wheel 42 to rotate. The worm wheel 42 rotates, which drives the rotating shaft 3 to rotate. The rotating shaft 3 rotates, which drives the rotating plate 31 to rotate. The rotating plate 31 rotates, which drives the fixed rod 32 to swing. The swing of the fixed rod 32 causes the two connecting plates 34 to move in opposite directions with the assistance of the auxiliary rod 39 through the square groove 35. The movement of the connecting plates 34 drives the guide plate 33 to move. The movement of the guide plate 33 will tighten and contract the two steel cables 12, thereby increasing the tension of the steel cables 12 on the crossbeam 6 and improving the stability of the crossbeam 6.

[0038] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
