Technical Field

[0001] This utility model relates to the field of roadbed settlement monitoring technology, and in particular to a roadbed settlement monitoring device with adjustable height. Background Technology

[0002] In the construction and maintenance of roadbed engineering, accurate monitoring of roadbed settlement is a core means of assessing the stability of the engineering structure and preventing safety hazards. Under the influence of factors such as self-weight, vehicle load, and natural environment, roadbeds are prone to uneven settlement. If timely monitoring and measures are not taken, serious problems such as pavement cracking and collapse may occur, threatening traffic operation safety. Therefore, using a roadbed settlement monitoring device with adjustable height can capture roadbed settlement data in real time and accurately, providing a reliable basis for engineering maintenance and decision-making, which is of great significance for ensuring the long-term stability of roadbed engineering.

[0003] When facing uneven ground, the fixed support structure (such as ground stakes or support legs) of existing roadbed settlement monitoring devices cannot flexibly adapt to changes in terrain, making it difficult to keep the equipment level. This not only leads to deviations in the alignment of the monitoring scale with the benchmark point, affecting the accuracy of settlement data measurement, but may also cause uneven stress on internal components due to equipment tilting, shortening the service life of the device and severely restricting the efficiency and reliability of monitoring work. Therefore, it is necessary to improve the above-mentioned problems. Utility Model Content

[0020] In this invention, three second motors are arranged in a triangular pattern on the top surface of the lifting cylinder. The output shafts of all three second motors are coaxially fixed to a auger drill bit 15 rotatably mounted inside the top surface of the lifting cylinder. A through hole corresponding to the auger drill bit 15 is provided on the inner bottom surface of the mounting base 7. The second motors are 39BYG stepper motors, offering high control precision and accurately controlling the drilling depth of the auger drill bit 15. The auger drill bit 15 is made of cemented carbide, possessing high hardness and wear resistance, suitable for various soil types. This structure drives the auger drill bit 15 to rotate via three second motors, thus achieving the desired drilling depth.

[0021] Working Principle: In use of this invention, the device is first moved to the monitoring point via pulley 1. The third motor is then started, driving the adjusting gear 13 to rotate. The adjusting gear 13 meshes with the half gear, causing the half gear to rotate around the axis, thereby adjusting the angle of the foot bracket 2. Depending on the flatness of the ground, multiple foot brackets 2 are adjusted to initially maintain the device in a horizontal state. After adjustment, the third motor is braked to fix the angle of the foot bracket 2. Next, the first motor is started, driving the sleeve 9 to rotate. The sleeve 9 engages with the lead screw 10 in a helical manner. Under the guidance of the sliding groove 8 and the guide protrusion, the lifting cylinder descends along the inner wall of the mounting base 7. During the descent of the lifting cylinder, the second motor is started, driving the auger drill.

Then, the height of the lifting cylinder is adjusted by the first motor, and the height of the fixed tripod 6 is adjusted. When the height of the measuring scale 4 is appropriate and aligned with the reference point, the first motor is turned off, and the height adjustment is completed. Finally, the roadbed settlement is monitored by the measuring scale 4. The fixed tripod 6 and the measuring scale fixing cylinder 5 can ensure the stability of the measuring scale 4 and ensure the accuracy of the monitoring data. If it is necessary to change the monitoring point, the first motor is started in reverse to raise the lifting cylinder, and the second motor is started in reverse to pull the auger bit 15 out of the ground. Then, the device can be moved by the pulley 1. At this point, the device is in use.
