Description

Technical Field

[0001] The present invention relates to the technical field of bridges, and in particular to a bridge status monitoring device for highway bridge engineering. Background Art

[0002] With the rapid development of transportation technology, the loads borne by highway bridges are increasing, which puts higher requirements on the stability and safety of bridge structures.

[0003] During the bridge construction process, large machinery is often parked on the surface of the erected bridge to cooperate with the tower crane to assist the construction of subsequent bridges. In order to monitor the changes in the bridge state caused by the vibration generated during the operation of the large machinery, bridge monitoring devices are often deployed on the bridge.

[0004] However, most of the bridge monitoring devices in the prior art are arranged between the bridge piers and the bridge deck. When the bridge is not completed, the maintenance of many bridge monitoring devices installed under the bridge often requires workers to perform high-altitude operations, which is time-consuming and labor-intensive in actual operation, and there is a lack of effective and easy-to-maintain monitoring devices.

[0005] How to solve the above technical problems is the subject faced by the present invention. Summary of the invention

[0006] The purpose of the present invention is to provide a bridge status monitoring device for highway bridge projects to solve the technical problem that current bridge monitoring devices are mostly arranged between bridge piers and bridge decks. When the bridge is not completed, the maintenance of many bridge monitoring devices installed under the bridge often requires workers to perform high-altitude operations, and the actual operation is relatively time-consuming and laborious.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: A bridge condition monitoring device for highway bridge engineering, comprising a triangular base and a plurality of leveling components fixed to multiple ends of the triangular base;

[0008] The top of the triangular base is structured with three columns in a circular array, and the columns are provided with diagonal brace components for auxiliary support, the three diagonal brace components are distributed in a circular shape, the tops of two adjacent columns are jointly provided with a tilt detection component, and the top of the other column is fixedly provided with an angle indication structure;

[0010] The present invention realizes the arrangement and support of the tilt detection component and the angle indication structure on the bridge deck through a triangular base provided with three columns. When the bridge vibrates and the angle deflects during the construction of large equipment, the U-frame provided with the indication component maintains a horizontal state under the influence of gravity, and the device provided with the angle indication structure will tilt with the inclination of the bridge, so that the bridge state is monitored by the indication component in cooperation with the angle indication structure, and long-term monitoring is maintained through two pressure sensors located on both sides of the U-frame. When the inclination angle is too large, the monitoring gap between the pressure sensor and the U-frame is continuously reduced, so that the pressure sensor abuts against one side of the U-frame, thereby triggering a bridge tilt alarm. Since it is arranged on the bridge deck, the high-altitude operation of the staff is eliminated during maintenance, and the working environment is optimized. In addition, the split design is adopted, and the two pressure sensors arranged on the U-shaped seat and the indication component arranged on the U-shaped frame can be removed, which saves time and effort during maintenance operations and is convenient for the staff to perform maintenance.

When the bridge vibrates and the angle deflects during the construction of large equipment, the U-frame provided with the indication component remains horizontal due to the influence of gravity, and the device provided with the angle indication structure will tilt with the inclination of the bridge, so that the bridge state is monitored by the indication component in cooperation with the angle indication structure, and long-term monitoring is maintained through two pressure sensors located on both sides of the U-frame. When the inclination angle is too large, the monitoring gap between the pressure sensor and the U-frame is continuously reduced, so that the pressure sensor abuts against one side of the U-frame, thereby triggering a bridge tilt alarm. Since it is arranged on the bridge deck, the high-altitude operation of the staff is eliminated during maintenance, and the working environment is optimized. In addition, the split design is adopted, and the two pressure sensors provided on the U-shaped seat and the indication component provided on the U-shaped frame can be removed, which saves time and effort during maintenance operations and is convenient for the staff to perform maintenance.

Since it is arranged on the bridge deck, the high-altitude operation of the staff is eliminated during maintenance, and the working environment is optimized. In addition, the split design is adopted, and the two pressure sensors 404 provided on the U-shaped seat 401 and the indication component 5 provided on the U-shaped frame 403 can be removed, which saves time and effort during maintenance operations and is convenient for the staff to perform maintenance.

[0032] In an embodiment of the present invention, in order to make the triangular base 1 in a horizontal state on the bridge deck to improve the monitoring accuracy, the leveling assembly includes a sleeve 8, the sleeve 8 is constructed at one end of the triangular base 1, and a guide rod 9 is movably arranged in the sleeve 8, and a bottom plate 10 is constructed at the bottom end of the guide rod 9. A plurality of through holes A are equidistantly provided on the outer edge surface of the guide rod 9, and a through hole B is provided at the bottom of the outer edge surface of the sleeve 8, and a pin 11 passing through the corresponding through hole A is inserted in the through hole B. By pulling out the pin 11, the position of the guide rod 9 in the sleeve 8 can be adjusted, so that the triangular base 1 is in a horizontal state on the bridge deck, thereby improving the monitoring accuracy.

[0033] In the embodiment of the present invention, in order to improve the stability of the monitoring device and facilitate the tilt monitoring, the diagonal support assembly 3 includes a support tube 301, a rubber anti-slip sleeve is fixedly installed at the bottom end of the support tube 301, and a support rod 302 is movably arranged in the support tube 301, and a fixed clamp A303 arranged at the top end of the column 2 is hingedly installed at the top of the support rod 302, a fixed clamp B304 is fixedly installed at the top of the outer edge surface of the support tube 301, and a diagonal support rod 305 is hingedly installed on one side of the fixed clamp B304, and the end of the diagonal support rod 305 away from the fixed clamp B304 is hinged.

[0034] Working principle: This embodiment provides a bridge status monitoring device for highway bridge engineering. When in use, the position of the guide rod 9 in the sleeve 8 is adjusted by pulling out the pin 11, so that the triangular base 1 is in a horizontal state on the bridge deck, and then the extension length of the support rod 302 in the support tube 301 is adjusted to achieve stable support for the three columns 2. After the adjustment is completed, the indication component 5 and the two pressure sensors 404 can be powered by the power supply equipment. When the bridge vibrates and the angle deflects during the construction of large equipment, the U-shaped frame 403 with the indication component 5 remains horizontal due to the influence of gravity, and the device with the angle indication structure will tilt with the inclination of the bridge, thereby transmitting the light beam transmitter provided on the extension arm 502. 503 emits a light beam, which cooperates with the inclination indicator 7 to read the inclination angle, thereby monitoring the bridge status, and maintaining long-term monitoring through the two pressure sensors 404 located on both sides of the U-shaped frame 403. When the inclination angle is too large, the monitoring gap between the pressure sensor 404 and the U-shaped frame 403 continues to shrink, so that the pressure sensor 404 abuts against one side of the U-shaped frame 403, thereby triggering the bridge tilt alarm. Since it is arranged on the bridge deck, the staff is exempted from high-altitude operations during maintenance, and the working environment is optimized. In addition, the split design is adopted, and the two pressure sensors 404 arranged on the U-shaped seat 401 and the indicator component 5 arranged on the U-shaped frame 403 can be removed, which saves time and effort during maintenance operations and is convenient for the staff to perform maintenance.
