Description

Technical Field

[0001] This utility model relates to the field of foundation pit monitoring technology, and more specifically, to a BIM-based foundation pit monitoring device. Background Technology

[0002] The BIM (Building Information Modeling)-based foundation pit monitoring device is an intelligent device that integrates building information modeling technology with the monitoring needs of foundation pit engineering. By integrating modules such as laser ranging, image acquisition, and data transmission, it can realize deformation monitoring, stress analysis, and safety early warning of foundation pit engineering. The device is usually equipped with a BIM platform, which can link real-time monitoring data with the three-dimensional model to intuitively present key parameters such as the displacement of the surrounding soil and the stress of the support structure, providing a visual basis for engineering decision-making. It is widely used in the safety management of deep foundation pit construction in the fields of construction, transportation, and municipal engineering.

[0003] Traditional detection devices, such as the BIM-based foundation pit monitoring device (publication number CN222479335U), while improving buffering capacity through main structural design and effectively reducing vibration to enhance stability, still have significant shortcomings in practical applications. When deployed on uneven sites, they lack an automatic leveling mechanism, requiring manual adjustment for flatness. For example, when the device tilts, the onboard laser rangefinder, camera, and other sensors tilt synchronously, leading to systematic deviations in the monitoring data. This is especially problematic in cases of minor foundation pit deformation, where tilt-induced errors may mask actual structural risks and affect the reliability of the detection results. Therefore, a foundation pit monitoring device with automatic leveling capabilities is urgently needed to improve the accuracy and reliability of detection in complex site environments.

[0027] Please see Figures 1-6 A BIM-based foundation pit monitoring device includes a tracked vehicle 1. A platform plate 2 is provided on the upper surface of the tracked vehicle 1, and a battery 3 is provided on the lower surface of the platform plate 2. A bracket 4 is fixedly connected to the upper surface of the platform plate 2, and a semi-circular frame 5 is fixedly connected to the upper surface of the bracket 4. A connecting block 6 is fixedly connected to one end of the semi-circular frame 5. Four connecting blocks 6 are arranged in a circular array and evenly distributed. The four connecting blocks 6 are respectively fixedly connected to both ends of the semi-circular frame 5 and the upper surface of the balance connecting rod 18. A rotating shaft 8 is rotatably connected to the inner side wall of the connecting block 6 through a bearing 7. A balance connecting shell 9 is fixedly connected to one end of the rotating shaft 8. A balance connecting rod 18 is rotatably connected to the outer surface of the balance connecting shell 9 through the connecting blocks 6 and the rotating shaft 8. A BIM data acquisition device 20 is fixedly connected to the lower surface of one end of the balance connecting rod 18, and a counterweight 19 is fixedly connected to the other end of the balance connecting rod 18.

[0028] Specifically, when the tracked vehicle 1 travels to an uneven site, the entire device tilts. Under the weight of the counterweight 19, the balance connecting rod 18 rotates relative to the semi-circular frame 5 via the connecting block 6 and the rotating shaft 8. Since the four connecting blocks 6 are arranged in a circular array and are respectively connected to the semi-circular frame 5 and the balance connecting rod 18, the balance connecting shell 9 can rotate freely in two vertical dimensions (such as the X-axis and Y-axis) in the horizontal direction. At this time, the counterweight 19 tends to be vertically downward due to gravity, causing the balance connecting rod 18 to automatically adjust its posture, so that the BIM data acquisition device gradually returns to a vertical state. The balance connecting shell 9 is rotatably connected to the connecting block 6 via the rotating shaft 8, and the rotating shaft 8 has a built-in bearing 7 to reduce rotational resistance. The counterweight 19 is fixed at one end of the balance connecting rod 18, and the BIM data acquisition device is installed at the other end. The difference in gravity between the two ends forms a balancing torque. No matter which direction the device tilts, the counterweight 19 can automatically calibrate the levelness of the balance connecting rod 18 through gravity, so that the BIM data acquisition device can be adjusted. The data acquisition device is always perpendicular to the ground to avoid deviations in laser ranging or image acquisition caused by device tilt, thus improving the accuracy of monitoring data.

[0029] Please see Figures 1-6One end of the rotating shaft 8 is fixedly connected to a balance connecting housing 9. An electric telescopic rod 10 is fixedly connected to the upper surface of the balance connecting housing 9. One end of the telescopic rod of the electric telescopic rod 10 is fixedly connected to a connecting plate 11. A spring 12 is provided on the upper surface of the connecting plate 11 outside the telescopic rod of the electric telescopic rod 10. The upper end of the spring 12 abuts against the inner top wall of the balance connecting housing 9. An inclined sliding groove 14 is provided on the inner side wall of the rotating shaft 8. A compression brake block 16 is slidably connected to the inner side wall of the rotating shaft 8 through the inclined sliding groove 14 and the slider 15. A connecting rod 13 is rotatably connected to the inner side wall of the compression brake block 16. One end of the connecting rod 13 is rotatably connected to the inner side wall of the connecting plate 11 through a shaft. The outer surface of the rubber anti-slip pad 17 abuts against the inner side wall of the connecting block 6. A rubber anti-slip pad 17 is fixedly connected to the outer surface of the compression brake block 16.

[0030] Specifically, when the device moves to the designated position and the balance connecting rod 18 is automatically leveled by the counterweight 19, the electric telescopic rod 10 is energized and starts, extending downwards to push the connecting plate 11 downwards. The connecting plate 11, through the connecting rod 13, drives the squeezing brake block 16 to slide along the inclined slide groove 14 of the rotating shaft 8. The slider 15 moves from bottom to top within the inclined slide groove 14, causing the squeezing brake block 16 to expand outwards. The rubber anti-slip pad 17 tightly abuts against the inner wall of the connecting block 6. The squeezing brake block 16, through the slider 15 and... The inclined slide 14 is slidably connected, and one end of the connecting rod 13 is hinged to the connecting plate 11, and the other end is hinged to the compression brake block 16, forming a lever transmission. The spring 12 is sleeved on the outside of the electric telescopic rod 10. When the electric telescopic rod 10 is de-energized, the spring 12 pushes the connecting plate 11 upward, causing the compression brake block 16 to reset. The friction between the rubber anti-slip pad 17 and the connecting block 6 locks the rotational freedom of the rotating shaft 8, preventing external vibration or collision from causing the balance connecting rod 18 to shift, ensuring that the BIM data acquisition device remains stable during the inspection process. When it needs to be moved and leveled again, the electric telescopic rod 10 is de-energized, the spring 12 resets, and the compression brake block 16 is released, and the device returns to the free leveling state.

[0031] In summary, when using the overall equipment: the tracked vehicle 1 moves the device to the designated position, and then the BIM data acquisition device 20 detects the area to be inspected. When moving to the designated position, the ground flatness varies at different inspection locations, causing the entire device to tilt. At this point, the four rotating shafts 8 on the outer surface of the balancing connecting shell 9 allow the counterweight 19 to rotate freely at two vertical angles in the horizontal direction. Combined with the gravity of the balancing connecting rod 18, the counterweight 19, and the BIM data acquisition device 20, the device remains vertical regardless of tilt, improving the inspection effect. When the device is moved to the designated position for inspection, the electric telescopic rod... When the power is off, the telescopic rod of the electric telescopic rod 10 is retracted through the spring 12. Through the transmission action of the connecting rod 13, the slider 15 on the outer surface of the pressure brake block 16 moves from the lower end to the upper end of the inclined slide groove 14, thereby causing the upper surface of the rubber anti-slip pad 17 to abut against the inner wall of the connecting block 6. This locks the rotation of the four rotating shafts 8 at two angles, preventing external factors from interfering with the detection. When the device needs to be moved or leveled, the electric telescopic rod 10 is powered on, and its telescopic rod extends, causing the connecting plate 11 to descend. Through the transmission action of the connecting rod 13, the pressure brake block 16 is pulled down. At this time, the outer surface of the rubber anti-slip pad 17 disengages from the inner wall of the connecting block 6, allowing the device to automatically adjust its balance.

For all the fixed connections mentioned above, welding is preferred.
