Description

Technical Field

[0001] The present invention belongs to the technical field of bridge deformation monitoring, and particularly relates to a real-time bridge construction deformation monitoring device and method. Background Art

[0002] In modern transportation construction, as an important passage connecting different regions, bridges carry a large amount of people and goods. However, during the construction and use of bridge structures, they are affected by various factors, such as the natural environment (wind, rain, earthquake, etc.), changes in geological conditions, and human operations. These factors may cause the bridge to deform. If these deformations cannot be detected and processed in a timely manner, serious safety hazards may be caused, and even catastrophic accidents such as bridge collapses may occur.

[0003] In the related art, a real-time bridge construction deformation monitoring device and its monitoring method are disclosed, including: a base, with mounting holes for connecting to the bridge provided on the periphery of its surface; a lifting assembly, vertically installed on the surface of the base for adjusting the height of the monitoring component; an early warning mechanism, installed on the upper part of the lifting assembly, and the early warning mechanism is used to generate a prompt sound. When monitoring the deformation situation generated during the bridge construction process, the downward pressure generated by the deformation acts on the position of the first contact point, so that the first contact point can compress the second elastic member and move downward to contact the second contact point, thereby making the circuit conductive. At this time, the motor can work and drive the third elastic member and the knocking part to rotate through the drive shaft, so that a certain prompt sound can be generated under the knocking action of the knocking part on the sound-making part.

[0004] However, there are still deficiencies in the above structure. When the device is installed, the upward movement distance of its container cannot be restricted. If the upward movement distance is too large, it is easy to cause the water in the container to directly overflow during the installation process.

[0060] In addition, the present invention also provides a real-time bridge construction deformation monitoring method.

[0061] Please refer to Figures 1 to 5 together, wherein, a real-time bridge construction deformation monitoring method includes the following steps:

[0062] S1: Pass the installation bolt 30 through the installation hole 29 and install the substrate 1 on the pier;

[0063] S2: Start the biaxial motor 25, move the circular plate 21 upward so that the positioning ring 35 contacts the fixed plate 19, and make the top surface of the circular plate 21 flush with the pressing plate 15;

[0064] S3: Start the drive motor 5, move the lifting slider 6 upward, and make both the pressing plate 15 and the circular plate 21 fit against the bottom of the bridge;

[0065] S4: Start the biaxial motor 25, move the circular plate 21 downward to reset, and only make the pressing plate 15 contact the bottom of the bridge;

[0066] S5: When the bridge deforms, the pressing plate 15 will be pressed down, the hydraulic oil in the first cylinder 10 will be squeezed into the second cylinder 11, and the second piston 16 will be pushed. The magnetostrictive displacement sensor 18 is used to monitor the deformation amount.

[0067] The working principle of the real-time bridge construction deformation monitoring device provided by the present invention is as follows:

[0068] The first step: During installation, pass the installation bolt 30 through the installation hole 29, install the substrate 1 on the pier, start the biaxial motor 25, the biaxial motor 25 drives the second screw rod 26 to rotate, the second screw rod 26 drives the two internal thread blocks 27 to move away from each other, the internal thread blocks 27 push the C-shaped plate 22 through the inclined push rods 28, so that the C-shaped plate 22 moves upward, the C-shaped plate 22 drives the positioning rod 20 and the circular plate 21 to move upward, make the positioning ring 35 contact the bottom of the fixed plate 19, and make the top surface of the circular plate 21 flush with the top surface of the pressing plate 15;

[0069] Second step: Start the driving motor 5. The driving motor 5 drives the first screw rod 4 to rotate. The first screw rod 4 drives the lifting slider 6 to move upward. The lifting slider 6 drives the inclined plate 7 and the lifting plate 8 to move upward, so that both the pressing plate 15 and the circular plate 21 contact the bottom of the bridge. Subsequently, start the double-shaft motor 25 to make the circular plate 21 move downward, and only make the pressing plate 15 contact the bottom of the bridge;

[0070] Third step: When the bridge is deformed, it will press down the pressing plate 15.
