Example 2
The embodiment of the application discloses bridge construction is with pier straightness detection device that hangs down. The difference from embodiment 1 is that, referring to fig. 4 and 5, the observation mechanism 3 includes a first support frame 36 fixedly connected to the movable plate 18, the length direction of the first support frame 36 is orthogonal to the movable plate 18, a second support frame 37 is fixedly connected to the first support frame 36, and the second support frame 37 is orthogonal to the length direction of the first support frame 36.

When the pier side wall is inclined, the movable plate 18 attached to the pier side wall is inclined, and the scale indicated on the first scale 38 and the second scale 39 by the pull rope 33 is different. Thus, whether the side wall of the bridge pier is vertical can be judged by the scales indicated by the pull rope 33 on the first scale 38 and the second scale 39.

Then, the movable plate 18 is rotated around the second hinge shaft 17, so that the movable plate 18 is attached to the side wall of the bridge pier, and the perpendicularity of the movable plate 18 and thus the perpendicularity of the side wall of the bridge pier can be obtained by observing the scales indicated by the pull ropes 33 on the first scale 38 and the second scale 39.
When the detection position needs to be changed, the position of the movable plate 18 can be adjusted and pushed to the position to be detected on the side wall of the bridge pier through the cooperation of the turntable 13, the first linear driving piece 14, the second linear driving piece 19 and the connecting rod 16, and the whole detection device does not need to be frequently moved, so that the problem that the detection efficiency is low due to the fact that the detection device needs to be frequently moved when detecting the perpendicularity of different positions of the bridge pier in the related art can be improved.
