When the device is used, a worker firstly fixes the two bases 2011 around the detected bridge pier, confirms that the detected bridge pier is positioned at the round point of the circle centers of the two bases 2011, then fixes the two bases 2011 on the ground by using the existing fixing device, then fixes the four connecting plates 101 on the lower sides of the two annular fixing seats 1 by using the connecting piece, connects the two annular fixing seats 1 into an integral ring by using the existing fixing device, at the moment, the two annular fixing seats 1 are positioned on the outer part of the bridge pier, then sequentially rotates four rocking bars, the four rocking bars drive the adjacent gear sets 102 to rotate, the gear sets 102 drive the adjacent threaded rods 103 to synchronously rotate by using the spline, and the four threaded rods 103 are respectively matched with the threads of the adjacent connecting plates 101 to enable the four threaded rods to circumferentially rotate and simultaneously move to the side close to the bridge pier.
In the process of moving the four threaded rods 103 (described by taking the movement of the threaded rods 103 on the front side and the rear side as an example), after the threaded rods 103 on the front side are moved backward to the limit position, the worker stops rotating the front rocker, rotates the rear rocker, and moves the rear threaded rod 103 forward to the limit position, after the arc plate on the rear side moving column 1031 is attached to the side wall of the bridge pier in the process of moving the rear threaded rod 103 forward, the bridge pier provides reverse acting force to the rear moving column 1031, the threaded rods 103 on the rear side drive the adjacent moving column 1031 to compress the adjacent first elastic pieces 104 in the process of moving, meanwhile, the storage force of the rear first elastic pieces 104 is increased after being compressed, the two annular fixing bases 1 are moved backward, the acting force generated by the bridge pier on the rear moving column 1031 is transmitted to the front moving column 1031 by the two annular fixing bases 1, the front moving column 1031 is simultaneously compressed by force, until the front first elastic pieces 104 are compressed by force, when the front first elastic pieces 104 are compressed to the two annular fixing bases 1, and the two annular fixing bases are not matched with the first elastic pieces on the two annular fixing bases, and the two annular fixing bases are matched with each other, and the two annular fixing bases are fixed on the two annular fixing bases 1.
After the annular fixing seat 1 is fixed, the staff installs four second movable shafts 210 on the lower side of the annular fixing seat 1 through hinging seats, installs four first telescopic sleeves 202 on the upper sides of adjacent bases 2011 respectively, then installs a liquid storage tube 206 in an arc-shaped groove on the upper side of the annular fixing seat 1 and adjusts the position of the liquid storage tube so that racks on a push plate 207 are positioned at the positions meshed with the toothed rings 2, after the liquid storage tube 206 is installed, the staff installs a liquid storage box on the upper side of the left annular fixing seat 1 and communicates the liquid storage box with a second connecting pipe 208, then the staff places a gravity ball 106 in a storage tube 105, so that three movable rods 201 limit the gravity ball 106, prevent the gravity ball 106 from sliding down into an arc-shaped annular groove on the lower side of the annular fixing seat 1, and prevent the relative position of the gravity ball 106 from being changed when the bridge pier is inclined towards the initial position where the gravity ball 106 is located, so that the staff can produce wrong judgment.
After all the devices are installed and fixed, if the pier is settled, the relative vertical position of the pier is inclined, and in the process, the forward inclination of the pier is taken as an example for description:
if the bridge pier tilts forward, the annular fixing seat 1 is driven by the transmission of the four moving columns 1031 to tilt synchronously, in the process of tilting forward the annular fixing seat 1, the distance between the front side and the base 2011 is gradually reduced, the distance between the rear side and the base 2011 is gradually increased, meanwhile, the two first moving shafts 203 on the front side move downwards under pressure, the two first moving shafts 203 on the rear side move upwards under tension, in the process, the two first moving shafts 203 on the front side respectively press the telescopic ends of the two adjacent first hydraulic telescopic rods 204 on the lower side downwards, so that hydraulic oil between the fixing parts of the first hydraulic telescopic rods 204 is conveyed into the liquid storage tube 206 through the adjacent first connecting tubes 205, the push disc 207 is driven to move rightward, the rack on the push disc 207 drives the toothed ring 2 to rotate, and the toothed ring 2 drives the three moving rods 201 to move synchronously through the arc grooves on the toothed ring 2, so that the three moving rods 201 are far away from each other.
In the process of moving the two first moving shafts 203 on the rear side upward, the first moving shafts 203 drive the telescopic ends of the two adjacent first hydraulic telescopic rods 204 on the upper side to move upward, and the hydraulic oil in the fixed parts of the two first hydraulic telescopic rods 204 on the upper part of the rear side is respectively extruded into the two adjacent first connecting pipes 205 and is conveyed into the liquid storage pipe 206.
