Description

Technical Field

[0001] This utility model relates to the field of support structure technology, specifically to an adjustable Bailey truss and pile cap beam windproof collaborative support structure. Background Technology

[0002] In bridge construction, especially for long-span bridges, wind load is a key factor affecting their stability. Bailey bridges have high strength and stiffness, and working together with pile cap beams, they can effectively distribute wind load and enhance the overall wind resistance stability of the bridge. This wind-resistant and coordinated support structure can ensure that the bridge remains stable in harsh wind environments and guarantee the safe use of the bridge.

[0003] The existing technology has the following problems: Existing devices cannot adjust the position of the threaded holes during use. The terrain and spatial layout of actual engineering sites are complex and diverse. In areas with irregular terrain or limited space, such as bridge construction in mountainous areas or support structure installation in narrow indoor spaces, the threaded holes in fixed positions may not be aligned with the pre-set connection points, resulting in inaccurate installation of the Bailey truss. In addition, existing devices cannot replace threaded hole blocks of different specifications. If different specifications of threaded hole blocks cannot be replaced, only a single specification of bolt connection can be used, which is difficult to meet the precise stress requirements of each part. This may lead to insufficient bolt connection strength in some parts with high stress, increasing the risk of structural damage due to connection failure. Utility Model Content

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following describes the utility model in conjunction with specific embodiments.

[0017] like Figure 1-3 As shown, this utility model provides an adjustable Bailey truss and pile cap beam windproof collaborative support structure, including a frame 1. Multiple inclined steel bars 4 are fixedly connected to the inner surface of the frame 1. A cap beam steel bar 3 is installed above the frame 1. Multiple ventilation holes 2 are opened on both the front and rear sides of the frame 1. A movable groove 5 is opened on the upper side of the frame 1. Multiple positioning holes 6 are opened on the lower side of the inner surface of the movable groove 5. Multiple sliding seats 8 are slidably connected to the inner surface of the movable groove 5. Sliding grooves 7 are opened on both the front and rear sides of the inner surface of the movable groove 5. A snap-fit ​​seat 9 is fixedly connected to the upper side of the sliding seat 8. The frame 1 serves as the basic frame of the entire windproof collaborative support structure. Multiple inclined steel beams 4, which are fixedly connected, enhance the structural strength and stability of the frame 1, enabling it to better withstand external forces. A cap beam steel beam 3 is installed on the top of the frame 1 for connecting with other structural components and transferring loads. Multiple ventilation holes 2 on the front and rear sides of the frame 1 can effectively reduce the force of wind load on the structure and reduce wind-induced vibration. A movable groove 5 is opened on the upper side of the frame 1 to provide a sliding track for the sliding seat 8. The sliding seat 8 can slide along the sliding groove 7 in the movable groove 5. The snap-fit ​​seat 9 fixed above it is used to connect the threaded hole block 18, thereby realizing the connection with components such as Bailey trusses. The whole structure forms an adjustable connection structure system.

[0018] like Figure 3-4As shown, this utility model provides a technical solution: Preferably, the outer wall of the sliding seat 8 is slidably connected to the sliding groove 7. A first knob 10 is rotatably connected to the right side of the sliding seat 8, and a worm gear 11 is fixedly connected to the left side of the first knob 10. The outer wall of the worm gear 11 is rotatably connected to the sliding seat 8, and a worm wheel 12 is meshed with the outer wall of the worm gear 11. A first threaded rod 13 is fixedly connected through the upper side of the worm wheel 12. A positioning pin 14 is threadedly connected to the outer wall of the first threaded rod 13. The outer wall of the positioning pin 14 is slidably connected to the sliding seat 8, and the outer wall of the positioning pin 14 is movably connected to the positioning hole 6. Two connecting plates 15 are fixedly connected to the outer wall of the positioning pin 14. Two limiting rods 16 are fixedly connected to the upper side of the inner surface of the sliding seat 8. The outer walls of the limiting rods 16 are slidably connected to the connecting plates 15. When it is necessary to adjust the position of the threaded hole, the first knob 10 is rotated, and the second threaded rod 14 is rotated. A knob 10 drives the worm gear 11, which is fixedly connected to it, to rotate. Since the worm gear 11 meshes with the worm wheel 12, the rotation of the worm gear 11 drives the worm wheel 12 to rotate. The first threaded rod 13, which is fixedly connected to the upper side of the worm wheel 12, rotates together with the worm wheel 12. The positioning pin 14, which is threadedly connected to the first threaded rod 13, cannot rotate due to the restriction of the sliding seat 8, and can only move along the axial direction of the threaded rod. The connecting plate 15, which is fixed to the outer wall of the positioning pin 14, slides on the limiting rod 16, which is fixed to the upper side of the inner surface of the sliding seat 8, and plays a guiding and limiting role to ensure that the positioning pin 14 moves linearly. After the positioning pin 14 moves to the appropriate position, it can cooperate with the positioning holes 6 at different positions on the lower side of the inner surface of the movable groove 5, thereby fixing the position of the sliding seat 8 in the movable groove 5, which indirectly adjusts the position of the threaded hole connected to the snap-fit ​​seat 9 to meet the requirements of different installation positions.

[0019] like Figure 5-6As shown, this utility model provides a technical solution: Preferably, the upper side of the snap-fit ​​base 9 has an opening 17, and the inner surface of the opening 17 is movably connected to a threaded hole block 18. Slots 19 are provided on both the front and rear sides of the threaded hole block 18. A second knob 20 is rotatably connected to the upper side of the snap-fit ​​base 9, and a second threaded rod 21 is fixedly connected to the lower side of the second knob 20. The outer wall of the second threaded rod 21 is rotatably connected to the snap-fit ​​base 9. A lifting block 22 is threadedly connected to the outer wall of the second threaded rod 21. A rotating plate 23 is rotatably connected to both the front and rear sides of the lifting block 22. A fixed plate 24 is rotatably connected to the other end of the rotating plate 23. Two fixed rods 25 are fixedly connected to both the front and rear sides of the inner surface of the snap-fit ​​base 9. An insert block 26 is slidably connected to the outer wall of the fixed rod 25. The outer wall of the insert block 26 is fixedly connected to the fixed plate 24 and movably connected to the slot 19. To replace the threaded hole block 18 of different specifications, the second knob 20 is rotated. The second knob 20 drives the second threaded rod 21 fixedly connected below to rotate. The lifting block 22, which is threadedly connected to the second threaded rod 21, cannot rotate due to the restriction of the locking seat 9. It can only move up and down along the axis of the second threaded rod 21. The rotating plates 23 connected to the front and rear sides of the lifting block 22 will change their angle as the lifting block 22 moves. The fixed plate 24 connected to the other end of the rotating plate 23 moves accordingly. The fixed plate 24 drives the insertion block 26 fixedly connected to it to slide on the fixed rod 25. When the lifting block 22 rises, the insertion block 26 is dislodged from the slot 19 of the threaded hole block 18. At this time, the original threaded hole block 18 can be taken out and replaced with a threaded hole block 18 of the required specification. After replacement, the second knob 20 is rotated in the opposite direction to make the insertion block 26 re-insert into the slot 19 of the new threaded hole block 18, so as to realize the replacement of threaded hole blocks 18 of different specifications to adapt to bolts of different diameters and strength grades and meet the precise mechanical requirements of each part.

[0020] The working principle of this adjustable Bailey truss and pile cap beam windproof collaborative support structure will be explained in detail below.

[0021] like Figure 1-6As shown, when the position of the threaded hole needs to be adjusted, the first knob 10 is rotated, which drives the worm 11 fixedly connected to it to rotate. Since the worm 11 meshes with the worm wheel 12, the rotation of the worm 11 drives the worm wheel 12 to rotate. The first threaded rod 13, which is fixedly connected to the upper side of the worm wheel 12, rotates together with the worm wheel 12. The positioning pin 14, which is threadedly connected to the first threaded rod 13, cannot rotate due to the restriction of the sliding seat 8, and can only move along the axial direction of the threaded rod. The connecting plate 15 fixed on the outer wall of the positioning pin 14 slides on the limiting rod 16 fixed on the upper side of the inner surface of the sliding seat 8, which plays a guiding and limiting role, ensuring that the positioning pin 14 moves linearly. After the positioning pin 14 moves to the appropriate position, it can cooperate with the positioning holes 6 at different positions on the lower side of the inner surface of the movable groove 5, thereby fixing the position of the sliding seat 8 in the movable groove 5, which indirectly adjusts the position of the threaded hole connected to the snap-fit ​​seat 9, meeting the requirements of different installation positions. When changing the threaded hole block 18 of different specifications, Rotating the second knob 20 causes the second threaded rod 21, which is fixedly connected below, to rotate. The lifting block 22, which is threadedly connected to the second threaded rod 21, cannot rotate due to the restriction of the locking seat 9. It can only move up and down along the axis of the second threaded rod 21. The rotating plates 23, which are rotatably connected to the front and rear sides of the lifting block 22, will change their angle as the lifting block 22 moves. The fixed plate 24, which is rotatably connected to the other end of the rotating plate 23, moves accordingly. The fixed plate 24 causes the insert block 26, which is fixedly connected to it, to slide on the fixed rod 25. When the lifting block 22 rises, the insert block 26 disengages from the slot 19 of the threaded hole block 18. At this time, the original threaded hole block 18 can be removed and replaced with a threaded hole block 18 of the required specification. After replacement, rotating the second knob 20 in the opposite direction causes the insert block 26 to be reinserted into the slot 19 of the new threaded hole block 18. This allows for the replacement of threaded hole blocks 18 of different specifications to adapt to bolts of different diameters and strength grades, meeting the precise mechanical requirements of various parts.
