Through the detection mechanism 3, the position measured by the detection plate 369 can be adjusted, and the distance between its measurement point and the device installation point can be adjusted, improving the diversity of measurement and obtaining more measurement data. It solves the problem that the distance between the measurement point of some existing devices on the bridge and the installation point on the pier is fixed, that is, the measurement position is fixed, resulting in a single and insufficient measurement data, which is prone to large errors, and improves the practicability of the device.

[0026] The detection component 36 includes a first rectangular frame 361, a first sliding rod 362, a U-shaped movable plate 363, a first spring 364, a second rectangular frame 365, a second sliding rod 366, a second spring 367, a slider 368 and a detection plate 369.

During the detection process, if the bridge undergoes longitudinal displacement, under the elastic action of the first spring 364, the U-shaped movable plate 363 will slide on the first sliding rod 362. If the bridge undergoes horizontal displacement, it will drive the detection plate 369 to horizontally displace through the anti-slip pad 4, and the slider 368 will slide on the second sliding rod 366. In case of any displacement, the corresponding displacement sensor 7 will sense the displacement amount and measure the data, and the staff can make corresponding processing after receiving the data. When it is necessary to detect at different positions on the bridge, the servo motor 33 is controlled to start, driving the lead screw 34 to rotate, driving the U-shaped connecting plate 35 to move, and then driving the first rectangular frame 361 to horizontally move, driving the detection plate 369 to move to different measurement points for detection.
