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.
[0030] Reference Figure 1 , Figure 2 , Figure 3This utility model provides an embodiment of an adjustable bridge support, comprising a base 1, with first support blocks 2 fixedly connected to the four upper corners of the base 1, a motor 3 fixedly connected to the upper right side of the base 1, a drive wheel 4 fixedly connected to the output end of the motor 3, a driven wheel 6 connected to the drive wheel 4 via a belt 5, a first connecting shaft 7 fixedly connected to the rear sides of both the drive wheel 4 and the driven wheel 6, a first connecting rod 8 fixedly connected to both outer sides of the first connecting shaft 7, a second connecting rod 10 rotatably connected to the first connecting rod 8 via a fixed shaft 9, a second connecting shaft 11 fixedly connected inside the second connecting rod 10, the second connecting shaft 11 fixedly connected inside the second support block 12, and the second support block 12 fixedly connected to the top plate 13. At the lower four corners, a connecting component is fixedly connected to one end of the fixed shaft 9. The connecting component is used to support and limit the top plate 13. The connecting component includes a sliding block 14, which is fixedly connected to one end of the fixed shaft 9. The sliding block 14 is slidably connected to the outside of the fixed rod 15. The fixed rod 15 is fixedly connected to the inside of the fixed frame 17. A first spring 16 is sleeved on the outside of the fixed rod 15. A first connecting block 18 is fixedly connected to the middle side of the upper part of the base 1. A connecting frame 19 is slidably connected to the outside of the first connecting block 18. The connecting frame 19 is fixedly connected to one side of the fixed frame 17. A second connecting block 20 is slidably connected to the upper side of the inside of the connecting frame 19. The second connecting block 20 is fixedly connected to the lower side of the top plate 13.
[0031] The starting motor 3 drives the driving wheel 4, belt 5, driven wheel 6, first connecting shaft 7, first connecting rod 8, fixed shaft 9 and second connecting rod 10 to rotate. At the same time, the fixed shaft 9 moves, causing the sliding block 14 to slide outside the fixed rod 15 and stretch the first spring 16. The second connecting rod 10 moves, causing the second connecting shaft 11, second support block 12 and top plate 13 to move. At the same time, the top plate 13 moves, causing the second connecting block 20 to slide inside the connecting frame 19. This allows the support height to be adjusted according to the actual needs of the bridge.
[0032] Reference Figure 1 , Figure 2 , Figure 4 The base 1 has a support frame 21 fixedly connected to each of its four outer corners. The support frame 21 has a support rod 22 slidably connected inside. The top of the support rod 22 is fixedly connected to a pressing block 23. The support rod 22 is fitted with a second spring 24. The support rod 22 has evenly distributed threaded holes 25 on the opposite side. The threaded holes 25 are threadedly connected to a support assembly, which is used to fix and support the base 1. The support assembly includes bolts 26, which are threadedly connected to the inside of the threaded holes 25. The support frame 21 is connected to the support rod 22 by bolts 26. The bottom of the support rod 22 is fixedly connected to a ground nail 27.
[0033] By manually pressing down on the pressing block 23, the support rod 22 is moved. At the same time, the pressing block 23 squeezes the second spring 24. The movement of the support rod 22 causes the ground nail 27 to be inserted into the soil. Then, the bolt 26 is manually turned and screwed into the bearing frame 21 and the threaded hole 25, which can fix and support the base 1.
[0034] Reference Figures 1-4 One end of the first spring 16 is fixedly connected to the inside of the fixed frame 17, and the other end of the first spring 16 is fixedly connected to the opposite side of the sliding block 14; the driving wheel 4 and the driven wheel 6 are both rotatably connected to the front side of the first support block 2, and the first connecting shaft 7 is rotatably connected to the inside of the first support block 2; the top end of the second spring 24 is fixedly connected to the lower side of the pressing block 23, and the bottom end of the second spring 24 is fixedly connected to the upper side of the support frame 21; the sliding block 14 is slidably connected to the inside of the fixed frame 17.
[0035] One end of the first spring 16 is fixedly connected to the inside of the fixed frame 17, and the other end of the first spring 16 is fixedly connected to the opposite side of the sliding block 14, thus supporting and limiting the sliding block 14. The driving wheel 4 and the driven wheel 6 are both rotatably connected to the front side of the first support block 2, and the first connecting shaft 7 is rotatably connected to the inside of the first support block 2, thus supporting and limiting the driving wheel 4, the driven wheel 6, and the first connecting shaft 7. The top end of the second spring 24 is fixedly connected to the lower side of the pressing block 23, and the bottom end of the second spring 24 is fixedly connected to the upper side of the support frame 21, thus supporting and limiting the support rod 22. The sliding block 14 is slidably connected to the inside of the fixed frame 17, thus supporting and limiting the sliding block 14.
[0036] Working principle: When using this device, starting the motor 3 drives the driving wheel 4 to rotate. The rotation of the driving wheel 4 drives the driven wheel 6 connected by the belt 5 to rotate. The rotation of the driving wheel 4 and the driven wheel 6 drives the first connecting shaft 7 to rotate. The rotation of the first connecting shaft 7 drives the first connecting rod 8 to rotate. The rotation of the first connecting rod 8 drives the second connecting rod 10 connected by the fixed shaft 9 to rotate. At the same time, the movement of the fixed shaft 9 causes the sliding block 14 to slide outside the fixed rod 15, thereby stretching the first spring 16. The movement of the second connecting rod 10 drives the movement of the second connecting shaft 11. The movement of the second connecting shaft 11 drives the movement of the second support block 12. The movement of the second support block 12 drives the movement of the top plate 13. The top plate 13 moves, causing the second connecting block 20 to slide inside the connecting frame 19. This allows the height of the support to be adjusted according to the actual needs of the bridge, adapting to different bridge design and construction requirements, and ensuring the stability and adaptability of the support. When the support is placed in the appropriate position, the pressing block 23 is pressed down manually. The pressing block 23 moves, causing the support rod 22 to move. At the same time, the pressing block 23 compresses the second spring 24. The movement of the support rod 22 causes the ground nail 27 to move, inserting the ground nail 27 into the soil. Then, the bolt 26 is manually turned to screw the bolt 26 into the bearing frame 21 and the threaded hole 25, providing support and limiting for the support rod 22. This enables the base 1 to be fixedly supported, thereby improving the overall stability of the support.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
