Description

Technical Field

[0001] The present application relates to the technical field of detection devices, and in particular to a road bridge settlement and displacement detection device. Background Art

[0002] Bridges generally refer to structures built on rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology, or meet other transportation needs to make passage more convenient. During the use of bridges, they will sink due to their own gravity and external factors. The settlement is a continuous accumulation process. When the accumulation reaches a certain level, it will cause the bridge to break and cause major safety accidents. Therefore, it is necessary to detect the settlement and displacement of the bridge.

[0003] Bridge settlement is usually carried out through manual regular inspection. The staff uses a level and a steel ruler to directly observe the bridge settlement. The operation is cumbersome and the accuracy is easily affected by human factors, the error is large, and it cannot provide timely warnings and accurately analyze the settlement of the bridge. Therefore, improvements are now made to a road bridge settlement displacement detection device. Utility Model Content

By observing the scale to read the moving distance of the moving block, the descent height of the bridge body can be conveniently and accurately read. When the lower end of the L-shaped bracket continues to move downward and contacts with the pressure sensor, it means that the settlement distance of the bridge will exceed a reasonable range. The pressure sensor transmits the signal to the signal processing module, and the signal processing module promptly sends an alarm signal to prompt the bridge monitoring personnel.

The guide rod is set to prevent the moving blocks from positional displacement when moving.

[0009] As a preferred technical solution of the present application, the number of the moving block, the moving groove and the scale are two and are symmetrically distributed on both sides of the gear. The length of the scale and the moving groove are the same and the positions are corresponding. The initial position of the moving block corresponds to the position of the zero scale line of the scale.

[0010] By adopting the above technical solution, two sets of data are collected through two scales for comparison to avoid errors. By observing the scale to read the moving distance of the moving block, the descent height of the bridge body can be easily and accurately read.

By observing the scale 13 to read the moving distance of the moving block 11, the descent height of the bridge body can be conveniently and accurately read. When the lower end of the L-shaped bracket 5 continues to move downward and contacts the pressure sensor 14, it means that the bridge settlement distance will exceed a reasonable range.

By setting the guide rod 8, the moving block 11 can be prevented from position displacement when moving.

[0030] In this embodiment, if Figure 2 and 3 As shown, there are two moving blocks 11, two moving grooves 12 and two scales 13, which are symmetrically distributed on both sides of the gear 9. The scale 13 and the moving groove 12 have the same length and corresponding positions. The initial position of the moving block 11 corresponds to the position of the zero scale line of the scale 13. When in use, two sets of data are collected through two scales 13 for comparison to avoid errors. By observing the scale 13 to read the moving distance of the moving block 11, the descent height of the bridge body can be conveniently and accurately read.

When in use, by setting the sealing groove 20 and the sealing block 21, rainwater can be prevented from entering the fixing hole 18 and causing corrosion to the fixing bolts 19.

[0035] Working principle: The L-shaped bracket 5 and the road bridge pier 2 are fixedly connected together by the fixed block 4, so that when the bridge sinks, it will move downward with the L-shaped bracket 5.
