Description

Technical Field

[0001] This utility model relates to a roadbed settlement detection device, specifically a roadbed settlement detection device for the reconstruction and expansion of expressways in mountainous areas, and belongs to the field of roadbed settlement technology. Background Technology

[0002] Roadbed settlement refers to the subsidence of the embankment due to improper selection of embankment fill material, unreasonable filling methods, and insufficient compaction, under the combined effects of load, water, and temperature. After highways are put into use, they may also experience overall or localized subsidence of the roadbed due to the combined effects of climate factors and traffic loads. These issues are collectively referred to as roadbed settlement.

[0003] Utility model patent CN221567091U discloses a roadbed settlement detection device, including a roadbed, a base on top of the roadbed, a settlement coordinate fixedly connected to the top of the base, and anchor rods movably connected to the left and right sides of the base via pins, with the bottom ends of the anchor rods extending into the interior of the roadbed. This utility model improves the installation method of existing settlement detection devices by using an auxiliary plug-in method to fix it inside the roadbed, preventing loose roadbed soil from affecting the installation stability of the settlement detection device.

[0004] During highway expansion, it is necessary to monitor roadbed settlement to avoid road damage. Although the detection device in the aforementioned patent improves operational stability, it can only perform single-point detection, which is insufficient to cope with errors at different measurement points and reduces the accuracy of the measurement results. Therefore, we provide a roadbed settlement detection device for highway reconstruction and expansion in mountainous areas to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a roadbed settlement detection device for the reconstruction and expansion of expressways in mountainous areas in order to solve the above-mentioned problems, thereby addressing the issue of errors that are easily generated in single-point detection in the prior art.

[0006] This utility model is achieved through the following technical solution: a roadbed settlement detection device for the reconstruction and expansion of expressways in mountainous areas.

[0007] The device includes a fixed base, inside which is a positioning mechanism. The positioning mechanism includes a push plate and a rotating disk, and the rotating disk is rotatably connected to the fixed base. The surface of the push plate is fixedly connected with ground anchors, and the ground anchors are slidably connected to the fixed base. The middle part of the fixed base is provided with a lifting mechanism, which includes a fixed sleeve and a fixed plate. The fixed sleeve is fixedly connected to the fixed base, and the surface of the fixed plate is fixedly connected with equally spaced detection devices.

[0008] Preferably, the fixed base is internally connected to a slide rail, and the push plate is slidably connected to the slide rail. The surface of the push plate is rotatably connected to a connecting rod. The slide rail fixes the push plate, thereby improving the stability of the push plate's linear sliding.

[0009] Preferably, the other end of the connecting rod is rotatably connected to the rotating disk, and a worm gear is fixedly connected to the top of the rotating disk. The worm gear is rotatably connected to the fixed base. The rotating disk is controlled to rotate by the worm gear, so that the connecting rod drives the push plate to slide linearly.

[0010] Preferably, the worm gear is meshed with a worm, and the worm is rotatably connected to a fixed base. A first motor is fixedly connected inside the fixed base, and the output end of the first motor is fixedly connected to the worm. The first motor controls the rotation of the worm, which in turn drives the worm gear to rotate.

[0011] Preferably, a sliding ring is slidably connected to the surface of the fixing sleeve, a support rod is fixedly connected to the surface of the fixing plate, and the bottom of the support rod is fixedly connected to the sliding ring. A level is fixedly connected to the surface of the fixing plate. The fixing plate is supported and fixed by the sliding ring and the support rod, thereby improving the stability of the fixing plate during operation.

[0012] Preferably, a sliding rod is fixedly connected to the middle of the fixed plate, and the sliding rod is slidably connected to the fixed sleeve. A lifting plate is fixedly connected to the bottom end of the sliding rod. The lifting plate drives the sliding rod to move up and down, thereby adjusting the fixed plate to a suitable height.

[0013] Preferably, the fixed sleeve has a groove inside, and a slider is slidably connected inside the groove. The slider is fixedly connected to the lifting plate. The groove and the slider limit the lifting plate and prevent the lifting plate from rotating randomly.

[0014] Preferably, a threaded rod is threadedly connected to the middle of the lifting plate, and a second motor is fixedly connected inside the fixed sleeve. The output end of the second motor is fixedly connected to the threaded rod. The threaded rod is rotated by the second motor, thereby controlling the up and down movement of the lifting plate.

[0015] This utility model provides a roadbed settlement detection device for the reconstruction and expansion of expressways in mountainous areas, which has the following beneficial effects:

[0016] 1. The roadbed settlement detection device for the reconstruction and expansion of the expressway in this mountainous area uses a rotating disc to drive a push plate to move the ground anchors outward, fixing the base in the soil and preventing the base from swinging randomly, thus improving the stability of the foundation detection. The fixing sleeve positions the fixing plate, and the fixing plate is used to install and position the detection equipment. Several detection devices are used to detect different targets, reducing the error of roadbed settlement detection and improving the accuracy of roadbed settlement detection.

[0017] 2. The roadbed settlement detection device for the reconstruction and expansion of the expressway in this mountainous area uses a connecting rod to drive a push plate to move linearly. The push plate is fixed by a slide rail to improve the stability of the linear sliding of the push plate. The rotation of the rotating disk is controlled by a worm gear, which causes the connecting rod to drive the push plate to slide linearly. The rotation of the worm is controlled by a first motor, which in turn drives the worm wheel to rotate. The worm and worm wheel have self-locking properties to prevent the worm wheel from rotating randomly and improve the stability of the worm wheel's operation. The fixed plate is supported and fixed by a sliding ring and a support rod, which improves the stability of the fixed plate's operation.

[0018] 3. The roadbed settlement detection device for the reconstruction and expansion of the expressway in this mountainous area uses a level to detect the horizontal state of the fixed plate, ensuring that several detection devices are kept horizontal and improving the accuracy of the detection equipment for the roadbed. The lifting plate drives the sliding rod to move up and down, adjusting the fixed plate to a suitable height. The sliding groove limits the slider, which in turn limits the lifting plate, preventing it from rotating arbitrarily and improving the stability of the lifting plate's up and down sliding. The second motor controls the rotation of the threaded rod, thereby controlling the up and down movement of the lifting plate. Attached Figure Description

The positioning mechanism 3 includes a push plate 301 and a rotating disk 305, and the rotating disk 305 is rotatably connected to the fixed base 1. A ground anchor 302 is fixedly connected to the surface of the push plate 301, and the ground anchor 302 is slidably connected to the fixed base 1. By rotating the rotating disk 305, the push plate 301 drives the ground anchor 302 to move outward, fixing the fixed base 1 inside the soil, preventing the fixed base 1 from swinging randomly, and improving the stability of the foundation test.

[0029] The fixed base 1 is internally fixedly connected to a slide rail 303, and the push plate 301 is slidably connected to the slide rail 303. The surface of the push plate 301 is rotatably connected to a connecting rod 304. The connecting rod 304 drives the push plate 301 to move linearly. The slide rail 303 fixes the push plate 301, thereby improving the stability of the linear sliding of the push plate 301.

[0030] The other end of the connecting rod 304 is rotatably connected to the rotating disk 305. The top of the rotating disk 305 is fixedly connected to the worm gear 306, and the worm gear 306 is rotatably connected to the fixed base 1. The rotating disk 305 is controlled to rotate by the worm gear 306, so that the connecting rod 304 drives the push plate 301 to slide linearly.

[0031] The worm gear 306 is meshed with a worm 307, and the worm 307 is rotatably connected to the fixed base 1. The fixed base 1 is internally fixedly connected to a first motor 308, and the output end of the first motor 308 is fixedly connected to the worm 307. The first motor 308 controls the rotation of the worm 307, which in turn drives the worm gear 306 to rotate. The worm 307 and the worm gear 306 have self-locking properties to prevent the worm gear 306 from rotating arbitrarily and to improve the stability of the worm gear 306's operation.

[0032] Please see Figure 1 and Figure 3 A lifting mechanism 4 is provided in the middle of the fixed base 1. The lifting mechanism 4 includes a fixed sleeve 401 and a fixed plate 402. The fixed sleeve 401 is fixedly connected to the fixed base 1. Detection devices 2 are fixedly connected to the surface of the fixed plate 402 at equal intervals. The fixed plate 402 is positioned by the fixed sleeve 401. The detection devices 2 are installed and positioned by the fixed plate 402. Different targets are detected by several detection devices 2, thereby reducing the error of roadbed settlement detection and improving the accuracy of roadbed settlement detection.

[0033] A sliding ring 411 is slidably connected to the surface of the fixed sleeve 401, and a support rod 410 is fixedly connected to the surface of the fixed plate 402, with the bottom of the support rod 410 fixedly connected to the sliding ring 411. A level 403 is fixedly connected to the surface of the fixed plate 402. The fixed plate 402 is supported and fixed by the sliding ring 411 and the support rod 410, improving the stability of the fixed plate 402 during operation. The level 403 is used to detect the horizontal state of the fixed plate 402, keeping the several detection devices 2 in a horizontal state and improving the accuracy of the detection devices 2 in detecting the roadbed.

[0034] A sliding rod 407 is fixedly connected to the middle of the fixed plate 402, and the sliding rod 407 is slidably connected to the fixed sleeve 401. A lifting plate 404 is fixedly connected to the bottom end of the sliding rod 407. The sliding rod 407 is moved up and down by the lifting plate 404 to adjust the fixed plate 402 to a suitable height.

[0035] The fixed sleeve 401 has a groove 405 inside, and a slider 406 is slidably connected inside the groove 405. The slider 406 is fixedly connected to the lifting plate 404. The groove 405 limits the slider 406, thereby limiting the lifting plate 404, preventing the lifting plate 404 from rotating arbitrarily, and improving the stability of the lifting plate 404 sliding up and down.

[0036] The lifting plate 404 is threadedly connected to the middle of a threaded rod 408. A second motor 409 is fixedly connected inside the fixed sleeve 401, and the output end of the second motor 409 is fixedly connected to the threaded rod 408. The second motor 409 controls the rotation of the threaded rod 408, thereby controlling the lifting plate 404 to move up and down.

[0037] The testing equipment 2, the first motor 308 and the second motor 409 are existing technologies, and this application will not go into detail about their parameters and models.

[0038] In use, the following steps are taken: First, the fixed base 1 is placed inside the hard soil. Using a level 403, the fixed plate 402 is adjusted to a horizontal state. The first motor 308 controls the rotation of the worm gear 307, and the worm wheel 306 controls the rotation of the rotating disk 305. The connecting rod 304 drives the push plate 301 to move linearly, causing the push plate 301 to move the ground anchor 302 outward, thus fixing the fixed base 1 inside the soil. The second motor 409 controls the rotation of the threaded rod 408, causing the lifting plate 404 to move the sliding rod 407 up and down, adjusting the fixed plate 402 to a suitable height. Several detection devices 2 are used to detect different targets. Through cross-detection, the error of roadbed settlement detection is reduced, and the accuracy of roadbed settlement detection is improved.
