[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The utility model provides a technical solution:

[0025] Example 1:

[0026] Combine Figure 1-2 to Figure 3 A bridge vibration monitoring device includes a support base 1, an adjustment mechanism 2 is provided on the top of the support base 1, and a positioning mechanism 3 is provided on the top of the adjustment mechanism 2.

[0027] The adjusting mechanism 2 includes a threaded rod 28, which is rotatably connected to both sides of the top of the support seat 1. The tops of the two threaded rods 28 are fixedly connected to a worm gear 21, and a worm 23 is meshed on the surface of the worm gear 21. A rotating member 27 is fixedly connected to both sides of the worm 23. The surface of the worm 23 is rotatably connected to a support member 25, and the support member 25 is fixedly connected to the top of the support seat 1.

[0028] Furthermore, there are two threaded rods 28 symmetrically arranged on both sides of the support 25 . When the threaded rods 28 on both sides rotate, they can drive the sliding plate and the vibration sensor 33 to move up and down.

[0029] Furthermore, the surface of the threaded rod 28 is threadedly connected to a sliding member 29, the top of the sliding member 29 is fixedly connected to a connecting member 24, and both sides of the connecting member 24 are fixedly connected to connecting plates 26. The connection member 24 is set to ensure stability between the sliding members 29 on both sides.

[0030] Furthermore, the tops of the threaded rods 28 are rotatably connected to support frames 22, and the support frames 22 are fixedly connected to both sides of the top of the support seat 1. The support frames 22 are set to support the threaded rods 28 on both sides, thereby preventing the threaded rods 28 from tilting during rotation.

[0031] Example 2:

[0032] See Figure 4 On the basis of the first embodiment, the positioning mechanism 3 is further obtained to include a vertical plate 31, which is fixedly connected to the top of the connecting plate 26, and a mounting member 34 is fixedly connected to the top of the vertical plate 31. A vibration sensor 33 is arranged in the mounting member 34, and the mounting member 34 can be supported and fixed by the vertical plate 31.

[0033] Furthermore, positioning plates 35 are provided on both sides of the vibration sensor 33, and support rods 36 are fixedly connected to the surface of the positioning plates 35. The two support rods 36 are slidably connected to both sides of the mounting member 34. The positioning plates 35 can be supported by the provided support rods 36.

[0034] Furthermore, a handle 32 is fixedly connected to the side of the support rod 36 away from the vibration sensor 33, and a spring is sleeved on the surface of the support rod 36. The spring is arranged on one side of the positioning plate 35. Under the action of the elastic force of the spring, the positioning plates 35 on both sides can be driven to move towards each other, so that the vibration sensor 33 can be positioned, thereby realizing the installation of the vibration sensor 33.

[0035] In actual operation, when this device is used, first pull the handles 32 on both sides in directions away from each other. At this time, the handles 32 on both sides can drive the positioning plates 35 on both sides to move in directions away from each other. Then, place the vibration sensor 33 inside the mounting member 34, and then loosen the handles 32. Under the action of the elastic force of the spring, the positioning plates 35 on both sides can be driven to move towards each other, so that the vibration sensor 33 can be positioned, thereby realizing the installation of the vibration sensor 33. According to the above principle, the vibration sensor 33 can be disassembled by repeating the reverse steps. By setting a vibration sensor that is easy to install and disassemble, Sensor 33, when the vibration sensor 33 is damaged, it can be disassembled and repaired in time, ensuring the normal use of the vibration sensor 33. When the bridge needs to be monitored, the rotating part 27 can be rotated, and the rotating part 27 drives the worm 23 and the worm wheel 21 to rotate synchronously, and drives the threaded rods 28 on both sides to rotate synchronously. During the rotation of the threaded rods 28 on both sides, the sliding plate and the vibration sensor 33 can be driven to move up and down. By setting a vibration sensor 33 with an adjustable height, it can adapt to bridges of different heights, expanding the scope of use of the device. Under the action of the vibration sensor 33, vibration monitoring of the bridge can be realized.
