[0002] In today's transportation infrastructure construction, prefabricated bridges are increasingly dominant as an efficient way of building bridges. They have shown significant advantages in shortening construction periods and improving the standardization of project quality. They are widely used in various highway, railway and urban bridge projects. From the perspective of construction process, the construction of prefabricated bridges is highly dependent on precise segment lifting and docking procedures. In the process of building prefabricated bridges, the lifting and precise docking of bridge segments are key links.

[0003] After searching, the Chinese patent number CN111005321A discloses an assembled bridge building docking device, including a base, a support block and a top block. The upper end of the base is provided with a mounting groove, the lower end of the support block extends into the mounting groove and is fixedly connected with a positioning shaft, the end of the positioning shaft away from the support block is rotatably connected to the side of the mounting groove away from the groove through a first rolling bearing, a cylindrical groove is provided at the upper end of the support block, a T-shaped groove is provided at the bottom of the cylindrical groove, an adjustment mechanism is connected in the T-shaped groove, a hydraulic cylinder is provided in the cylindrical groove, the lower end of the hydraulic cylinder is connected to the adjustment mechanism, and a protrusion is fixedly connected to the output end of the hydraulic cylinder.

[0004] During the use of the above-mentioned device, when placing the bridge, due to the position deviation when the bridge falls on the abutment, it needs to be adjusted multiple times to meet the technical requirements. On the one hand, if it is placed directly above the adjustment mechanism during placement, cracks may appear on the bridge. On the other hand, the engagement between the adjustment mechanisms may be damaged, reducing the service life. Therefore, an assembled bridge construction docking device is proposed. Summary of the invention

[0005] The purpose of the present invention is to solve the problems existing in the prior art, that when placing a bridge, due to the position deviation when the bridge falls on the abutment, multiple adjustments need to be made to meet the technical requirements. On the one hand, cracks may appear on the bridge if it is placed directly above the adjustment mechanism during placement. On the other hand, the meshing between the adjustment mechanisms may be damaged, reducing the service life. A prefabricated bridge construction docking device is proposed.

[0011] There are multiple groups of small springs for weighing on the spring plate. The side of the compression spring away from the pressure plate is fixedly connected with a flip plate. The multiple groups of springs carefully designed on the spring plate play a key buffering role. When the small bridge is placed, the spring can respond quickly and absorb the instantaneous impact force, effectively eliminating the hidden dangers of cracks and surface damage on the bridge caused by rigid collision, and effectively ensuring the structural integrity of the small bridge.

[0018] The present invention has the following beneficial effects:

[0019] 1. In the present invention, the multiple groups of springs carefully designed in the spring plate play a key buffering role. When the small bridge is placed, the spring can respond quickly and absorb the instantaneous impact force, effectively eliminating the hidden dangers of cracks and surface damage on the bridge caused by rigid collision, and effectively ensuring the structural integrity of the small bridge. In this way, the small bridge can always maintain the bearing performance at the beginning of the design during subsequent use, greatly reducing the maintenance and reinforcement procedures and related cost investment caused by initial damage, ensuring its long-term and stable service, and the flip plate and the compression plate cooperate with the compression spring to form a powerful protection system.

[0020] 2. In the present invention, on the one hand, the compression plate bears the deadweight of the large bridge over a large area, and the compression spring evenly disperses the pressure to prevent excessive concentration of local pressure from causing damage to the bottom surface of the bridge; on the other hand, during the placement and use of the bridge, the crank rod accurately controls the inclination of the flip plate and a series of ingenious structural linkages. It only needs to be completely flipped over to effectively avoid the risk of bridge deformation caused by improper operation or unreasonable load, thereby protecting the safety of the large bridge structure in all directions and extending its service life.

[0044] The working principle of the assembled bridge construction docking device in the present invention is that when it is used, when placing a small bridge, it is directly placed on the surface of the spring plate 14. The multiple groups of springs on the surface of the spring plate 14 can be used for buffering. When it is taken out, the telescopic column 10 is lifted, and the telescopic block 15 on the surface of the spring plate 14 lifts the bridge to the required height, and then it can be taken away at this time. If it is facing a large bridge, the crank rod 19 is controlled to rotate, and the crank rod 19 rotates to drive the connecting block 20 to move upward, and the rotating block 25 set in the notch of the connecting plate 13 rotates, and the sliding track 24 fixed on the side of the rotating block 25 and the flip The sliding bar 22 on the side of the rotating plate 21 slides, and when the crank rod 19 continues to rotate, the flip plate 21 will continue to tilt and finally be parallel to the surface of the connecting plate 13. At this time, a large bridge can be placed. Multiple groups of compression springs 30 are arranged between the pressure-resistant plate 27 and the flip plate 21. The bridge is placed on the surface of the side of the pressure-resistant plate 27 away from the connecting column 26. The compression spring 30 will be compressed by the gravity of the bridge, and then the connecting column 26 slides inside the connecting seat 28, and the pressure-resistant plate 27 is squeezed close to the flip plate 21. When it is taken, the lifting block 31 and the telescopic column 10 are moved upward to adjust the required height, and it can be taken at this time.

[0045] If the position of the bridge needs to be adjusted, the motor 7 can be controlled to rotate. The output end of the motor 7 drives the worm 6 to rotate, and the worm 6 engages with the worm wheel 5, and then drives the threaded rod 9 to rotate, so that the movable pier 12 drives the upper connecting plate 13 to slide on the top of the load-bearing plate 4. In this way, the horizontal adjustment can be made. When the bridge falls on the surface of the spring plate 14, after being buffered by the small springs on the surface, the telescopic column 10 is controlled to be extended and retracted, and the telescopic block 15 is controlled to move upward. At this time, the movement of the bridge in the vertical direction can be controlled to ensure the control of the adjustment distance.
