Description

Technical Field

[0001] The present invention relates to the technical field of monitoring instruments, in particular to a real-time monitoring instrument for the deviation of an installation axis of a small box girder. Background Art

[0002] As prefabricated structures, small box girders are easily mechanized and factory-based. As a mature construction method, box girder prefabrication accounts for over 70% of highway and railway bridge projects and is widely recognized by designers and constructors. Small box girders are widely used in bridge construction because they only have end cross beams, resulting in a simple visual effect under the bridge. Their low beam height offers advantages in areas with limited beam height and demanding landscape aesthetics. Their structural adaptability to varying widths allows for a wide range of applications.

[0003] The box girder axis real-time monitoring device targets the core needs of structural deformation monitoring during bridge construction and operation and maintenance. By integrating multiple types of sensors such as laser rangefinders, tilt sensors, and optical fiber strain gauges, combined with Beidou high-precision positioning and wireless transmission technology, it can achieve millimeter-level real-time monitoring of box girder axis offset, deflection, stress and strain and other parameters.

[0004] However, the existing small box girder installation axis deviation real-time monitoring device has the following shortcomings:

[0005] 1) Traditional small box girder axis monitoring mostly relies on manual periodic measurement or intermittent sampling of a single sensor, which has problems such as monitoring lag and data discontinuity, making it difficult to provide real-time feedback on deviation trends. The installation method usually lacks a flexible adjustment mechanism and relies on empirical positioning. It is easily affected by environmental vibration or installation errors, resulting in insufficient monitoring accuracy, weak equipment protection measures, and easy damage due to long-term exposure to outdoor environments. Maintenance requires complete disassembly, which is cumbersome.

[0006] 2) Traditional monitoring devices mostly use rigid fixation or threaded fastening methods, lack multi-directional adjustment and self-locking functions, and are easily affected by construction vibrations and cause displacement, resulting in monitoring data deviations. Their installation process relies on manual experience for positioning, lacks guiding and limiting structures, is inefficient and difficult to ensure repeatability. When exposed to outdoor environments for a long time, the equipment is susceptible to corrosion or wear due to the lack of a buffer seal design, requiring frequent shutdowns for maintenance.

[0007] 3) Traditional small box girder monitoring devices mostly use rigid fixation or threaded fastening methods, lacking refined adjustment mechanisms, resulting in installation and positioning relying on manual experience, which is prone to axis deviation and difficult to correct.

[0008] Therefore, we proposed a real-time monitoring device for the installation axis deviation of a small box girder in order to solve the above problems. Summary of the Invention
