Description

Technical Field

[0001] This utility model belongs to the field of roadbed monitoring technology, specifically a roadbed settlement monitoring device. Background Technology

[0002] Road surface settlement leads to a decrease in road surface smoothness, resulting in potholes, cracks, and other defects. Vehicles traveling on such surfaces will experience bumps and swaying, affecting driving comfort and safety. Severe settlement can even cause vehicles to lose control, leading to traffic accidents. For rail transit such as railways, road surface settlement can alter the geometry of the tracks. By monitoring road surface settlement, road infrastructure maintenance can promptly detect deformation of the road structure. When abnormal settlement data is detected, it can alert relevant departments to take timely measures for repair and reinforcement, preventing further damage and extending the service life of the road.

[0003] When using infrared laser monitoring, the infrared laser signal is easily affected by atmospheric conditions during transmission, causing scattering, absorption, and attenuation, thus affecting the accuracy and reliability of the monitoring. In severe weather, this can lead to significant errors in the monitoring data, or even prevent normal monitoring. If obstacles exist along the monitoring path, the infrared laser may be blocked, failing to reach the receiving end accurately, resulting in interrupted or erroneous monitoring data. Infrared laser monitoring equipment is inherently complex, with high manufacturing and development costs, and requires high-precision positioning and calibration equipment, further increasing costs. Therefore, this application proposes a roadbed settlement monitoring device. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Depend on Figures 1-7 The present invention includes a road surface 1 and a monitoring mechanism. An installation cylinder 2 is connected to the road surface 1. Two installation plates 6 are fixed on the road surface 1. Two U-shaped plates 5 are fixed on the installation cylinder 2 and are arranged opposite to the installation plates 6. The installation plates 6 are located inside the U-shaped plates 5 and slide against them. The installation plates 6 are provided with grooves 18. A limiting bolt 3 is slidably connected in the grooves 18 and slides against the inner wall of the grooves 18. The limiting bolt 3 passes through the U-shaped plates 5 and is slidably connected to them. A second spring 4 is fixedly installed on the limiting bolt 3 and the U-shaped plates 5.

[0025] During disassembly, pulling the limiting bolt 3 will pull it out of the groove 18, and the U-shaped plate 5 will no longer be limited. The mounting cylinder 2 will no longer be limited, and the mounting cylinder 2 can be removed. During installation, the mounting plate 6 is inserted into the U-shaped plate 5 and slides against it. The groove 18 is exactly opposite to the limiting bolt 3. When the limiting bolt 3 is released, the second spring 4 will drive the limiting bolt 3 to move into the groove 18 and slide against the inner wall of the groove 18. The second spring 4 can ensure the stability of the limiting bolt 3 in the groove 18.

[0026] The monitoring mechanism includes a channel 8 set on the road surface 1, a fixed plate 7 slidably connected in the channel 8, a triangular plate 10 fixedly installed in the channel 8, the triangular plate 10 abutting against the fixed plate 7, and a first spring 9 fixedly installed on the fixed plate 7 and the channel 8. When a vehicle passes over the road surface 1, it will cause a short-term slight deformation of the road surface 1, which will cause the fixed plate 7 to move down, affecting the position of the moving block 23 on the scale plate 22. The first spring 9 can ensure that the fixed plate 7 always abuts against the channel 20, avoiding the short-term slight deformation from affecting the judgment.

[0027] A transmission component is installed at one end of the fixed plate 7. The transmission component includes a gear plate 16 fixedly installed at one end of the fixed plate 7. The gear plate 16 is meshed with a large gear 17, and the large gear 17 is meshed with a small gear 19. The small gear 19 is fixedly connected to the transmission rod 13. The transmission rod 13 is installed on the transmission component, and a moving component is fixedly connected to the transmission rod 13. The moving component includes a threaded rod 12 fixedly connected to the transmission rod 13. The threaded rod 12 is threadedly connected to a fixing block 15. The upper end of the fixing block 15 is connected to the bottom of the connecting rod 11. The mounting cylinder 2 is fixedly connected to the upper part of the connecting plate 14. The fixed block 15 slides against the upper end of the connecting plate 14. Two connecting rods 11 are installed on the moving part. The mounting cylinder 2 is provided with a sliding groove 20 and two through grooves 21 opposite to the sliding groove 20. The connecting rods 11 slide against the inner wall of the through groove 21. A scale plate 22 is installed in the sliding groove 20. A moving block 23 is fixedly installed on the upper end of the two connecting rods 11. The moving block 23 is located on the upper end of the scale plate 22 and slides against it.

[0028] When road surface 1 settles, it causes one end of fixed plate 7 to move downwards. Fixed plate 7 and triangular plate 10 work together in a lever-like manner, dividing fixed plate 7 into a 1:3 ratio. The downward movement of one end of fixed plate 7 caused by road surface 1 causes the other end of fixed plate 7 to move upwards three times. Fixed plate 7 then causes gear plate 16 to move upwards, which in turn causes large gear 17 to rotate. Large gear 17 then causes small gear 19 to rotate. The gear on gear plate 16 is larger than the gear on large gear 17, and the gear on large gear 17 is larger than the gear on small gear 19. The wheel and gear plate 16 can rotate the small gear 19 multiple times by moving it slightly, thereby amplifying the settlement distance of the road surface 1. The rotation of the small gear 19 will drive the threaded rod 12 to rotate. Since the fixed block 15 slides against the upper end of the connecting plate 14, the threaded rod 12 will drive the fixed block 15, which cannot rotate, to move on the connecting plate 14. The fixed block 15 will drive the connecting rod 11 to move. The connecting rod 11 will drive the moving block 23 to move on the scale plate 22. By observing the position of the moving block 23 on the scale plate 22, the settlement of the road surface 1 can be monitored.

[0029] Working principle: When road surface 1 settles, road surface 1 will cause one end of fixed plate 7 to move down. Fixed plate 7 and triangular plate 10 cooperate to form a lever shape. Triangular plate 10 divides fixed plate 7 into a 1:3 ratio. When road surface 1 causes one end of fixed plate 7 to move down, it will cause the other end of fixed plate 7 to move up three times. Fixed plate 7 will cause gear plate 16 to move up. The upward movement of gear plate 16 will cause large gear 17 to rotate. Large gear 17 will cause small gear 19 to rotate. The gear on gear plate 16 is larger than the gear on large gear 17. The gear on large gear 17 is larger than the gear on small gear 19. Moving gear plate 16 a little bit can cause small gear 19 to rotate multiple times, thereby increasing the settlement distance of road surface 1.

[0030] The rotation of the pinion 19 will drive the threaded rod 12 to rotate. Since the fixed block 15 slides against the upper end of the connecting plate 14, the threaded rod 12 will drive the fixed block 15, which cannot rotate, to move on the connecting plate 14. The fixed block 15 will drive the connecting rod 11 to move. The connecting rod 11 will drive the moving block 23 to move on the scale plate 22. By observing the position of the moving block 23 on the scale plate 22, the settlement of the road surface 1 can be monitored.

[0031] When the monitoring device needs to be disassembled, pulling the limit bolt 3 will pull the limit bolt 3 out of the groove 18, and the U-shaped plate 5 will no longer be limited. The mounting cylinder 2 will no longer be limited, and the mounting cylinder 2 can be disassembled. During installation, the mounting plate 6 is inserted into the U-shaped plate 5 and slides against it. The groove 18 is exactly opposite to the limit bolt 3. When the limit bolt 3 is released, the second spring 4 will drive the limit bolt 3 to move into the groove 18 and slide against the inner wall of the groove 18. The second spring 4 can ensure the stability of the limit bolt 3 in the groove 18.
