Description

Technical Field

[0001] This utility model relates to the field of bridge pier fixing technology, and in particular to a bridge pier fixing device for a swallow-shaped arch bridge. Background Technology

[0002] The structure of bridge pier fixing devices is a crucial component in ensuring the safety, stability, and long-term use of bridges. As a key structural support for bridges, the fixing devices for piers must be able to withstand various loads borne by the bridge while ensuring effective connection between the pier and other parts of the bridge. The structural design of bridge pier fixing devices typically involves foundation, connection, and support components, each with its specific function. Currently, bridge piers are generally fixed to the surrounding foundation surface through concrete structures. While these structures are stable and strong, they still require regular inspection and maintenance to check for cracks and other defects. For arch bridge piers with multiple structural surfaces, inspection often relies on manual operation, which is cumbersome. Therefore, this invention proposes an arch bridge pier fixing device that facilitates subsequent damage inspection, eliminates the need for manual on-site inspection, improves the timeliness of maintenance through real-time monitoring, and avoids potential safety hazards.

[0023] A power control device 3 is installed on the side plate 2, and a drive box 7 is installed on both sides of the side plate 2. The drive box 7 contains a lead screw 9 and a motor 10. The motor 10 drives the lead screw 9. A slide block 8 is slidably installed inside the drive box 7. The slide block 8 and the lead screw 9 form a helical pair. A shielding folding layer 801 is attached to both ends of the slide block 8. The shielding folding layer 801 is connected to the top two ends of the drive box 7 to block external sand and dust. A connecting rod 6 is rotatably installed on the slide block 8. One end of the connecting rod 6 is rotatably connected to the swing frame 4 to control the swing frame 4 to swing back and forth.

[0024] The first testing mechanism includes an angle motor 11 located inside the side plate 2, which drives an angle frame 12. The angle frame 12 is equipped with a moving belt 13 and a moving motor 14, which drives the moving belt 13 and controls the movement of the moving slide 15. An adjusting motor 16 is located on the moving slide 15, and a belt structure is provided on the output shaft of the adjusting motor 16. An mounting rod 18 and a mounting screw 19 are provided on the parallel frame 17. The mounting rod 18 and the mounting screw 19 are movably mounted on the moving slide 15. The belt structure on the output shaft of the adjusting motor 16 and the mounting screw 19 form a helical pair. A second motor 20 and a second screw 21 are provided on the parallel frame 17. The second motor 20 drives the second screw 21, which drives the testing piece.

[0025] The detection component includes a detection slide 22, on which a tilting motor 23 is mounted. A control cylinder 24 is mounted on the output shaft of the tilting motor 23. A protective cylinder 25 is mounted on the extension rod of the control cylinder 24. A vision detector 26 is mounted on the detection slide 22.

[0026] The working principle is as follows: Pier 1 is connected to the surrounding foundation surface through steel bar 101, so that pier 1 is fixed on the foundation surface; a swing frame 4 is rotatably installed on the side plate 2, and the photovoltaic panel 5 on the swing frame 4 can generate photovoltaic power to provide power; specifically, through the operation of motor 10, the lead screw 9 rotates, controlling the slide 8 to slide back and forth, and under the connection of the connecting rod 6, the swing frame 4 swings back and forth, which can shake off the sand and dust accumulated on the swing frame 4, and can also shield the top surface of pier 1 to prevent sand and soil from falling onto the top surface of pier 1.

[0027] Furthermore, when performing damage inspection on the surface of pier 1, specifically the top surface, inclined surface, and front side of pier 1, the angle frame 12 is rotated by the angle motor 11, which adjusts the angle of the parallel frame 17. This allows for angle adjustment between the top surface and inclined surface of pier 1. When the parallel frame 17 is parallel to the top surface of pier 1, the top surface of pier 1 is inspected; when the parallel frame 17 is parallel to the inclined surface of pier 1, the inclined surface of pier 1 is inspected. Specifically, the moving belt 13 is moved by the moving motor 14. The belt 13 drives the movable slide 15 to move along the surface of the pier 1. By adjusting the operation of the motor 16, the screw 19 is rotated, which in turn moves the parallel frame 17, that is, adjusts the relative position of the parallel frame 17 on the top surface or inclined surface of the pier 1. Then, by the operation of the second motor 20, the screw 21 is rotated, which moves the detection slide 22. The surface is visually inspected by the vision detector 26, that is, the surface of the pier 1 is inspected for cracks or other broken conditions. The inspection information is remotely transmitted to the information receiving system, which facilitates timely maintenance by maintenance personnel.

[0028] When not in operation, the control cylinder 24 is rotated by the flip motor 23, and the control cylinder 24 controls the movement of the protective cylinder 25, thereby controlling the relative position of the protective cylinder 25 and the vision detector 26, and thus controlling the connection between the protective cylinder 25 and the vision detector 26 to protect the lens of the vision detector 26; for the front side of the pier 1, the movement belt 27 is moved by the second moving motor 28, and the second moving belt 27 drives the detection component to move, so as to detect the damage to the front side of the pier 1.
