[0002] The roadbed is the basis of the track or the road surface, and is a soil work structure formed by excavation or filling. The roadbed needs to ensure a certain flatness during construction.

[0003] The 3-meter ruler method is suitable for measuring the flatness of the compacted roadbed and road surface. One test point can be selected every 100 m. During the test process, the angle of the ruler should be paid attention to, and the ruler should be in good contact with the road surface without suspension. The eyes should be level with the plug gauge reading when measuring the gap. The plug gauge and reading process of the 3-meter ruler method requires a lot of time and manpower, and the detection efficiency is low.

[0004] In the prior art, the Chinese utility model patent document with the authorization announcement number CN218116068U discloses a roadbed flatness detection device for roadbed construction. The triangular scraper and the triangular reinforcing plate are arranged, which is beneficial to scraping the protruding part of the roadbed through the triangular scraper arranged in a triangular shape, and guiding the excess material to the outside. It can be seen that it can scrape the roadbed, but it cannot measure the maximum gap between the horizontal sliding ruler and the road surface, and cannot reflect the unevenness of the road surface through the gap data.

[0005] Therefore, it is necessary to design a flatness detection device for roadbed construction which can automatically complete the detection of the maximum gap between the ruler and the road surface, reduce labor costs, and improve the detection efficiency to solve the technical problems faced at present.

Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0024] like Figures 1 to 5As shown, a flatness detection device for roadbed construction includes a crossbar 1, with support pipes 2 fixedly installed at both ends of the crossbar 1. A support plate 3 is fixedly installed at the bottom end of each support pipe 2. A detachable moving mechanism 5 is installed on the crossbar 1, capable of moving from one end to the other. A distance sensor 6 and a control box 7 are installed on one side of the detachable moving mechanism 5. The distance sensor 6 is used to detect the distance between itself and the top of the roadbed. The control box 7 contains a controller 74, with the distance sensor 6 connected to the controller 74. A display screen 71 is connected to the controller 74 and is located on the outside of the control box 7. In this embodiment, the two ends of the crossbar 1 are connected to... The support pipe 2 and the support plate 3 are used to support the top of the roadbed to be tested. The detachable moving mechanism 5 drives the distance sensor 6 to move along the crossbar 1 from one end to the other. During the movement, the distance sensor 6 continuously detects the distance between itself and the ground. The controller 74 presets the vertical distance between the distance sensor and the bottom of the support plate 3. After the detachable moving mechanism has moved, the maximum gap value is obtained by subtracting the maximum distance value detected by the distance sensor 6 from the preset value in the controller 74. By moving the distance sensor 6 along the crossbar 1 through the detachable moving mechanism 5, the detection of the maximum gap of the road surface can be completed automatically, reducing manual labor costs and improving detection efficiency.

[0025] In some embodiments, the detachable moving mechanism 5 has a C-shaped bracket 56.

By controlling the upper axle seat 55 to move down or up through the adjustment component, the detachable moving mechanism 5 can be slidably clamped on or removed from the crossbar 1. The traveling motor 53 is connected to the controller 74, and the controller 74 can control the traveling motor 53 to drive the traveling wheel 52 to rotate, thereby realizing the movement of the detachable moving mechanism 5 on the crossbar 1.

[0026] In some embodiments, the adjusting assembly has an adjusting screw 57 rotatably connected to the top of the upper shaft seat 55, and the adjusting screw 57 is threadedly connected to the top of the C-shaped bracket 56; rotating the adjusting screw 57 causes the threaded structure between the adjusting screw 57 and the C-shaped bracket 56 to drive the adjusting screw 57 to move the upper shaft seat 55 up and down.

[0027] In some embodiments, guide rods 58 are uniformly arranged on the top of the upper shaft seat 55, and the guide rods 58 are slidably connected to the top of the C-shaped bracket 56. The stability of the upper shaft seat 55 can be improved by the slidable connection between the guide rods 58 and the top of the C-shaped bracket 56.

[0028] In some embodiments, the bottom sides of the C-shaped bracket 56 are respectively provided with proximity switches 59 corresponding to the support tubes at both ends of the crossbar 1. The proximity switches 59 are connected to the controller 74. When the detachable moving mechanism 5 is at one end of the crossbar 1, one proximity switch 59 is triggered. When the detachable moving mechanism 5 moves to the other end of the crossbar 1, another proximity switch 59 is triggered.

[0029] In some embodiments, the control box 7 is provided with a first button 72 and a second button 73; wherein the first button 72 is a reset button, used to reset the last detected reading on the display screen 71; the second button 73 is a detection start button, when the detachable moving mechanism 5 is at one end of the crossbar 1, a proximity switch 59 is triggered, and pressing the second button 73 starts the walking motor 53 to drive the detachable moving mechanism 5 to move to the other end of the crossbar 1 until another proximity switch 59 is triggered, at which point the detachable moving mechanism 5 stops and completes the detection.

[0030] In some embodiments, an anchor rod 4 that penetrates the support plate is slidably disposed inside the support pipe 2; during testing, the anchor rod 4 is inserted into the roadbed to fix the support plate 3 and the support pipe 2 to the top of the roadbed, so as to prevent the crossbar 1 from moving during the measurement process.
