Description

Technical Field

[0001] This utility model relates to the field of bridge rotation technology, specifically a real-time displacement monitoring device for bridge rotation support legs. Background Technology

[0002] Bridge rotation construction refers to a construction method in which a bridge is first prefabricated and cast-in-place, offset from its designed axis, and then rotated back to the designed axis using a rotating system with a very low coefficient of friction. Finally, expansive concrete is injected into the rotating system to seal and close the bridge. During construction, it is necessary to measure the horizontal displacement at representative points during the bridge rotation using observation instruments and equipment. Monitoring and analyzing the regularity of horizontal displacement aims to understand whether the hydraulic structure is functioning normally under the influence of internal and external loads and foundation deformation, providing a basis for the safe operation of the project.

[0003] The real-time displacement monitoring device for bridge slewing supports, application number CN202322620406.7, involves installing several displacement monitoring devices on the bridge slewing support device. The position of the bridge slewing is determined by detecting the received pressure. However, there is a gap between adjacent displacement monitoring devices, making it impossible to accurately determine the position when the bridge slewing moves within the gap. At the same time, when pressure is applied to the support device, adjacent displacement monitoring devices will also feel the pressure, making the data prone to errors. Therefore, it is necessary to propose a real-time displacement monitoring device for bridge slewing supports. Utility Model Content

Detailed Implementation

[0013] 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.

[0014] Please see Figure 1-4 This utility model provides a technical solution: a real-time displacement monitoring device for a bridge rotation support foot, comprising a U-shaped base plate 1, a top plate 2 fixedly installed on the upper end of the base plate 1, a roller rotatably connected to the upper end of the top plate 2, a T-shaped groove 3 formed on the outer side wall of the base plate 1, a T-shaped slider 4 slidably connected within the T-shaped groove 3, one end of the T-shaped slider 4 extending outside the base plate 1 and fixedly installed with a threaded rod 5, a threaded sleeve 6 threadedly connected to the wall of the threaded rod 5, and a support rod 7 fixedly connected to the outer side wall of the threaded sleeve 6 via a bearing, and a slidably connected... The support sleeve 8 has an annular groove 9 inside. An annular block 10 is fixedly sleeved on the support rod 7 and slidably connected in the annular groove 9. A spring 11 is sleeved on the support rod 7. An L-shaped connecting block 12 is fixedly connected to the outer wall of the support sleeve 8. The end of the connecting block 12 away from the support sleeve 8 extends into the roller. A ball groove 13 is opened on the connecting block 12. A first ball 14 is tumbling in the ball groove 13. A positioning chip 15 is fixedly installed inside the connecting block 12. A positioning signal receiver 19 is fixedly installed on the base plate 1.

[0015] The bottom plate 1 is filled with concrete. The connection between the bottom plate 1 and the top plate 2 is fixed by welding. After the bottom plate 1 is filled with concrete and cured, the top of it is sealed by the top plate 2 to form a bridge rotation slide.

[0016] The T-shaped slider 4 has a ball bearing hole 16, and a second ball bearing 17 is rolled inside the ball bearing hole 16. When the T-shaped slider 4 moves in the T-shaped groove 3, it will be supported by the second ball bearing 17, thereby reducing the friction between the T-shaped slider 4 and the T-shaped groove 3, thus facilitating the movement of the T-shaped slider 4.

[0017] The threaded sleeve 6 is fixedly installed on the outer wall of the threaded sleeve 6, and the threaded sleeve 6 can be rotated by rotating the handle 18.

[0018] The lower end of the spring 11 abuts against the lower end of the annular groove 9, and the upper end of the spring 11 abuts against the lower surface of the annular block 10, so that the spring 11 pushes the support sleeve 8 downward under the support of the support rod 7 and the annular block 10.

[0019] Specifically, when using this utility model, firstly, by rotating the handle 18, the threaded sleeve 6 is pushed, so that the threaded sleeve 6 is threadedly connected to the threaded rod 5. Then, the support rod 7 and the support sleeve 8 are straightened, and then the connecting block 12 is pulled upward, so that the connecting block 12 rises to avoid abutting against the outer hub of the roller. Then, the threaded sleeve 6 is rotated and moved on the threaded rod 5. The movement of the threaded sleeve 6 will drive the support rod 7, the support sleeve 8, and the connecting block 12 to move synchronously, so that the connecting block 12 is inserted into the inner hub of the roller. At this time, the connecting block 12 can be released, and the spring 11, supported by the support rod 7 and the annular block 10, pushes the support sleeve 8 downward. The support sleeve 8 drives the connecting block 12 to descend into the inner hub of the roller and locks it inside. When the bridge rotates, the roller will move... The bridge rotates on the sliding track, and the rollers pull the connecting block 12 and the positioning chip 15 to move. The connecting block 12 pulls the T-shaped slider 4, and the T-shaped slider 4 moves synchronously within the T-shaped groove 3. The T-shaped slider 4 supports the threaded rod 5, threaded sleeve 6, support rod 7, support sleeve 8, and connecting block 12. During the movement, the spring 11 continuously pulls downward, causing the connecting block 12 to roll at the bottom of the inner hub of the roller via the first ball 14. The connecting block 12 and the positioning chip 15 are kept at the lowest position of the inner hub of the same roller, so that the positioning chip 15 maintains horizontal movement and synchronous movement with the bridge rotation. At this time, the movement distance and position of the bridge rotation can be accurately and in real time confirmed by the mutual positioning between the positioning chip 15 and the positioning signal receiver 19.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
