[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 are within the protection scope of the present utility model.

[0020] A roadbed filling quality inspection device includes a mobile vehicle 1. The corners of the bottom of the mobile vehicle 1 are equipped with moving wheels (not shown in the figure). The moving wheels facilitate the movement of the mobile vehicle 1 and provide convenience for the staff. A push handle 8 is installed at one end of the mobile vehicle 1. The push plate 8 can push the mobile vehicle 1, further providing convenience for the staff. Fixed supports 101 are fixed on both sides of the top of the mobile vehicle 1. A mounting rod 2 is fixed between the two opposing fixed supports 101, and the two mounting rods 2 are arranged parallel to each other. Mounting brackets 3 are provided on both sides of the top of the mobile vehicle 1, and the bottom of the mounting brackets 3 is respectively mounted on the two mounting rods 2, thereby supporting and fixing the mounting brackets 3. Different testing devices 4 and 5 can be installed between the two mounting brackets 3 (the specific structure of the testing devices can be referred to in Embodiment 1 or Embodiment 2 below) so that multiple testing devices 4 and 5 can be switched back and forth between the two mounting brackets 3 to perform multiple tests on the roadbed.

[0021] In detail: The mounting bracket 3 includes a mounting base 301, and a limiting groove 306 is provided on one side of the mounting base 301. The limiting groove 306 can be set in a "U" shape. The limiting groove 306 serves to limit the first limiting shaft 404 or the second limiting shaft 507, preventing the testing equipment from rotating during use and affecting the accuracy of the test. A mounting hole 307 is also provided on one side of the mounting base 301, and a fixing bolt 308 passes through the mounting hole 307 and is threaded to the first threaded hole 405 or the second threaded hole 508, thereby fastening the testing equipment and preventing it from loosening during use; it has strong stability.

[0022] More specifically: Support rods 302 are fixed to both sides of the mounting base 301, and mounting cylinders 303 are fixed to the bottom of the support rods 302. The two mounting cylinders 303 are slidably mounted on the mounting rods 2, allowing for sliding adjustment of the mounting bracket 3. The distance between the two mounting brackets 3 can be adjusted according to the size of the testing equipment, providing high flexibility. It should be noted that the mounting cylinders 303 have two insertion holes 304, symmetrically arranged about the support rods 302. Several locking holes 201 are equidistantly spaced along the axial direction on the circumferential surface of the mounting rods 2. After the mounting bracket 3 is adjusted, the locking shaft 305 passes through the insertion holes 304 and is inserted into one of the locking holes 201, thus securing the mounting bracket 3 and preventing slippage during roadbed testing.

[0023] Example 1 The detection device 4 includes a "semi-circular" protractor 401, and a rotating shaft 402 is fixed at the center of the protractor 401. Rotating grooves 4021 are respectively opened at both ends of the rotating shaft 402, and an indicator needle 403 is rotatably installed inside the rotating groove 4021. Through the cooperation of the indicator needle 403 and the protractor 401, the inclination of the roadbed can be detected. In detail: the indicator needle 403 includes a pointer 4031, and a rotating ring 4032 is fixed to the top of the pointer 4031. The rotating ring 4032 is rotatably installed inside the rotating groove 4021. It should be noted that: a lubricant is provided at the connection between the rotating ring 4032 and the rotating groove 4021, so that the rotating ring 4032 can rotate smoothly and is not easy to jam. An indicator arrow 4033 is fixed to the bottom of the pointer 4031. The indicator arrow 4033 is used to indicate the angle marked on the protractor 401, so that the angle of roadbed inclination can be observed intuitively and clearly. A first limiting shaft 404 is fixed at the center of the rotating shaft 402, and both ends of the first limiting shaft 404 are respectively installed through the rotating shaft 402. The two ends of the rotating shaft 402 are respectively placed inside the limiting groove 306. Through the cooperation of the first limiting shaft 404 and the limiting groove 306, the detection device 4 is limited, preventing the protractor 401 from rotating when detecting the inclination of the roadbed, thereby improving the accuracy of the measurement and reducing errors.

[0024] A first threaded hole 405 is provided at the center of the rotating shaft 402. If the first limiting shaft 404 is completely placed inside the limiting groove 306, the fixing bolt 308 passes through the mounting hole 307 and is threaded into the first threaded hole 405, thereby fastening the protractor 401 and preventing the protractor 401 from loosening during use, thus providing strong stability.

[0025] When detecting the tilt angle of the roadbed: First, the detection device 4 is moved to the position to be detected by the mobile vehicle 1. If the roadbed is tilted, the multiple wheels of the mobile vehicle 1 will contact the roadbed, causing the mobile vehicle 1 to be tilted. The mobile vehicle 1 will then tilt the protractor 401 by means of the mounting rod 2 and the mounting bracket 3. Since the pointer 403 is always set downwards due to its own weight, the lowest scale value on the protractor 401 corresponds to the pointer 403, so that the tilt angle of the roadbed can be observed, thus playing the role of detecting the tilt of the roadbed.

[0026] Example 2 The testing device 5 includes a testing box 501, and two ends of the testing box 501 are respectively fixed with second limiting shafts 507. When the two second limiting shafts 507 are placed inside the limiting grooves 306, they serve to limit the circumferential movement of the testing box 501 and prevent the testing box 501 from rotating during movement. A second threaded hole 508 is provided at the axis of the second limiting shaft 507. When the second limiting shaft 507 is completely placed inside the limiting grooves 306, the fixing bolt 308 passes through the mounting hole 307 and is threadedly connected to the second threaded hole 508, thereby securing the testing box 501 and preventing the testing box 501 from rotating during use, thus providing strong stability.

[0027] The testing box 501 has a partition plate 502 inside, and several "L"-shaped fixing brackets are provided at the connection between the partition plate 502 and the testing box 501. The fixing brackets are used to fix the partition plate 502. The partition plate 502 divides the interior of the testing box 501 into a control chamber 503 and a testing chamber 504, and the control chamber 503 is located above the testing chamber 504. The lower part of the testing box 501 is fixed with a fixing protrusion 9, and several bolts pass through the fixing protrusion 9 and are threadedly connected to the moving vehicle 1, which further strengthens the testing box 501.

[0028] The detection chamber 504 is equipped with a detection component 505. In detail, the detection component 505 includes an electric telescopic rod 5051 installed in the detection chamber 504, and a lifting plate 5052 is installed at the telescopic end of the electric telescopic rod 5051 through the detection chamber 504. An ultrasonic detector 5053 is installed at the bottom of the lifting plate 5052. The ultrasonic detector 5053 can be used to detect whether there are gaps in the roadbed. It should be noted that a protective cover 6 is also fixed to the bottom of the testing box 501, and the lifting plate 5052 and the ultrasonic detector 5053 are located inside the protective cover 6. The protective cover 6 serves to protect the ultrasonic detector 5053 from damage due to collision.

[0029] The control system 506 includes a touch screen display 5061 installed on the testing box 501. The testing equipment 5 can be operated through the touch screen display 5061. The output terminal of the touch screen display 5061 is electrically connected to a controller (not shown in the figure) through a wire. The controller controls the electric telescopic pole 5061 and the ultrasonic detector 5063. The output terminal of the controller is electrically connected to the electric telescopic pole 5051 and the ultrasonic detector 5053 through wires, so that the electric telescopic pole 5051 drives the ultrasonic detector 5053 to move down and detect the roadbed.

[0030] The control chamber 503 is also equipped with a battery 5063, which is electrically connected to the touch screen 5061, the ultrasonic detector 5053, the controller, the electric telescopic rod 5051, and the ultrasonic detector 5053, thereby providing power.

[0031] When inspecting the roadbed, the inspection equipment 5 is first moved to the required inspection position using the mobile vehicle 1. Then, the electric telescopic pole 5051 is activated, which moves the lifting plate 5052 downward. This allows the ultrasonic detector 5053 to move downward, bringing it into contact with the roadbed and inspecting it. The ultrasonic detector 5053 can detect whether there are holes in the roadbed. The ultrasonic detector 5053 transmits the inspection information to the controller, which then transmits the information to the touch screen 5061. The touch screen 5061 displays the inspection results for easy observation by staff.
