[0002] In the process of highway construction and maintenance, pavement quality testing is a key link in ensuring road performance and safety. Through pavement quality testing, various performance indicators of highway pavement can be systematically measured, evaluated and analyzed, aiming to ensure that the pavement meets design requirements, ensures driving safety, improves comfort and extends service life.

[0003] In related technologies, in order to conduct road surface quality testing, it is necessary to take samples from highways, transport the samples to laboratories, and then conduct tests through road surface quality testing agencies, which reduces testing efficiency. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a test vehicle for carrying road quality testing institutions, aiming to at least partially solve the technical problem of reduced testing efficiency caused by transporting samples to laboratories for testing by road quality testing institutions.

[0005] The technical solution of this invention is as follows: A test vehicle for carrying a road quality testing mechanism includes: a frame, comprising a body and multiple traveling components, the body being used to carry the road quality testing mechanism, the multiple traveling components being spaced apart along the longitudinal direction of the body, the body having multiple vibrator mounting positions for carrying the vibrators of the road quality testing mechanism, the multiple vibrator mounting positions being spaced apart along the longitudinal direction of the body; two connecting joints disposed on the body, the two connecting joints being located at opposite ends of the body along the longitudinal direction of the body; a vehicle head, detachably connected to one of the two connecting joints; and two AGV vehicles, corresponding one-to-one with the two connecting joints, the AGV vehicles being detachably connected to the corresponding connecting joints.

[0006] In some implementations, multiple vibrator mounting positions are located along the longitudinal centerline of the vehicle body.

[0007] In some implementations, the vibrator is located between two adjacent walking components.

[0008] In some embodiments, the walking assembly includes: a plurality of wheels; and a plurality of connecting shafts rotatably disposed on the vehicle body, the two ends of the connecting shafts being connected to two of the wheels respectively.

[0009] In some embodiments, the wheel has a hub, and the hub is provided with a brake disc.

[0010] In some embodiments, the frame further includes at least four lifters connected to the vehicle body; wherein, along the longitudinal direction of the vehicle body, at least two of the at least four lifters are located on one side of the vehicle body, and the remaining four lifters are located on the other side of the vehicle body.

[0011] In some implementations, the lifter includes a hydraulic cylinder.

[0012] In some embodiments, the test vehicle further includes a hydraulic pump located on the vehicle body and connected to the hydraulic cylinder and the vibrator.

[0013] In some implementations, the vibrator mounting position has a through hole penetrating the vehicle body for the vibrator's actuating end to extend out.

[0014] In some implementations, the test vehicle further includes a generator disposed on the vehicle body.

[0015] The beneficial effects of the present invention include at least the following: The vehicle frame comprises a body and multiple traveling components. The body supports the road quality inspection mechanism. Multiple traveling components are spaced apart along the longitudinal direction of the body. The body has multiple vibrator mounting positions to support the vibrators of the road quality inspection mechanism. These multiple vibrator mounting positions are spaced apart along the longitudinal direction of the body. Therefore, the multiple traveling components ensure the stability of the supporting body, and consequently, the stability of the road quality inspection mechanism. Two connecting joints are located on the body, at opposite ends along the longitudinal direction. The front of the vehicle is detachably connected to one of these connecting joints. Two AGVs correspond one-to-one with the two connecting joints, and are detachably connected to their respective joints. Therefore, when conducting road quality inspections on highways, the road quality inspection mechanism is mounted on the body, which supports it. The body is connected to the front of the vehicle, which pulls the body. The body travels at high speed via the traveling components, enabling the road quality inspection mechanism to... The system allows for rapid arrival near the testing location, reducing the movement time of the road quality testing equipment and enabling quick relocation. Upon arrival, the vehicle head is separated from the body, and the AGV is connected to the corresponding connector, allowing for low-speed, small-range movement. The vehicle then propels the road quality testing equipment accurately to the testing location. The vibrator, installed at the vibration mounting position, contacts the road surface to vibrate and test its quality. This reduces the overall relocation time of the road quality testing equipment, eliminating the need for repeated disassembly and adjustment, simplifying the process, and saving significant manpower, resources, and time. It also improves testing efficiency, freeing the testing site from terrain limitations and significantly expanding the testing area. Furthermore, it eliminates the need for sampling, preserving the integrity of the highway surface and reducing procedures, further lowering labor intensity and improving testing efficiency.

[0023] Specific technical solutions will now be described in detail with reference to the accompanying drawings, which are not necessarily drawn to scale.

[0024] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 The test vehicle used to support a road quality testing mechanism in this embodiment includes: a frame 10, connecting joints 20, a front end 30, and an AGV vehicle 40. The frame 10 includes a body 11 and multiple traveling components 12. The body 11 supports the road quality testing mechanism. Along the longitudinal direction of the body 11, the multiple traveling components 12 are spaced apart. The body 11 has multiple vibrator mounting positions for supporting the vibrators 50 of the road quality testing mechanism. Along the longitudinal direction of the body 11, the multiple vibrator mounting positions are spaced apart. Two connecting joints 20 are located on the body 11, along the longitudinal direction of the body 11, at both ends of the body 11. The front end 30 is detachably connected to one of the two connecting joints 20. Two AGV vehicles 40 (Automated Guided Vehicles) correspond one-to-one with the two connecting joints 20, and the AGV vehicles 40 are detachably connected to their respective connecting joints 20.

[0025] Since the frame 10 includes a body 11 and multiple traveling components 12, the body 11 is used to support the road quality inspection mechanism. Along the longitudinal direction of the body 11, the multiple traveling components 12 are spaced apart. The body 11 has multiple vibrator mounting positions, which are used to support the vibrators 50 of the road quality inspection mechanism. Along the longitudinal direction of the body 11, the multiple vibrator mounting positions are spaced apart. Therefore, the stability of the body 11 can be ensured by the multiple traveling components 12, thereby ensuring the stability of the body 11 in supporting the road quality inspection mechanism. Since two connecting joints 20 are located on the body 11... Along the longitudinal direction of the vehicle body 11, two connecting joints 20 are located at both ends of the vehicle body 11. The vehicle head 30 is detachably connected to one of the two connecting joints 20. Two AGV vehicles 40 correspond one-to-one with the two connecting joints 20, and the AGV vehicles 40 are detachably connected to the corresponding connecting joints 20. Therefore, when the road surface quality is to be inspected on the highway, the road surface quality inspection mechanism is installed on the vehicle body 11, and the vehicle body 11 carries the road surface quality inspection mechanism. The vehicle body 11 is connected to the vehicle head 30, and the vehicle head 30 pulls the vehicle body 11. The vehicle body 11 is then moved by the traveling assembly. The AGV 12 travels at high speed, enabling the road quality inspection agency to quickly reach the vicinity of the inspection location, reducing the movement time of the road quality inspection agency and achieving rapid relocation. When the vehicle body 11 reaches the vicinity of the inspection location, the front 30 is separated from the vehicle body 11, and the AGV 40 is connected to the corresponding connecting joint 20, so that the vehicle body 11 can move at low speed and within a small range. The vehicle body 11 drives the road quality inspection agency to accurately reach the inspection location. Then, the vibrator 50 installed at the vibration installation position contacts the road surface and vibrates to detect the road quality. This reduces the overall relocation time of the road quality inspection agency, eliminates the need for repeated disassembly and adjustment of the road quality inspection agency, simplifies the process of moving the road quality inspection agency, saves a lot of manpower, material resources, financial resources and time, and improves the testing efficiency. At the same time, the inspection site is not limited by terrain, the inspectable area is greatly expanded, and the inspection efficiency is greatly improved. Moreover, there is no need to perform sampling operations, that is, there is no need to damage the road surface of the highway, ensuring the integrity of the highway road surface, reducing procedures, further reducing labor intensity, and improving inspection efficiency.

[0026] In some embodiments, the vehicle body 11, which uses multiple walking components 12, serves as the core component for supporting loads, suspension, and other support devices. It is mainly made of channel steel and steel plate bending parts, welded together, annealed, and then precision machined, giving it good rigidity and strength.

[0027] In some embodiments, the road quality testing agency has a measurement system mounted on the vehicle body 11. The vehicle body 11 carries the measurement system, which is mainly used for setting experimental parameters, collecting experimental data, and processing experimental data.

[0028] In some embodiments, using the AGV vehicle 40 to move the vehicle body 11 allows for low-speed movement along the inspection section, improving the movement accuracy of the vehicle body 11 during inspection. Operating the AGV vehicle 40 with a wireless controller enables the vehicle body 11 to move on the road surface, driving the road quality inspection mechanism forward, backward, left, and right. This reduces the relocation time of the road quality inspection mechanism, eliminates the need for repeated equipment disassembly and adjustment, simplifies the relocation process, saves significant manpower, material resources, financial resources, and time, and improves inspection efficiency.

[0029] Because the vibration frequency is high when multiple vibrators 50 are working, it can easily affect the safety of the vehicle body 11. Combined with... Figure 2 In some embodiments, to ensure the safety of the vehicle body 11, multiple vibrator mounting positions are all located along the longitudinal centerline of the vehicle body 11. When the multiple vibrators 50 are working, the vibration of the multiple vibrators 50 can be evenly distributed on the vehicle body 11, avoiding vibration concentration in a certain area of ​​the vehicle body 11, thus preventing damage to the vehicle body 11 and extending the service life of the vehicle body 11. For example, the multiple vibrators 50 are arranged at equal intervals.

[0030] Combination Figure 1 In some embodiments, the vibrator 50 is located between two adjacent walking components 12 to avoid interference, ensure the normal operation of the vibrator 50, and also ensure that the vehicle body 11 can move normally.

[0032] In some embodiments, the wheel 121 has a hub with a brake disc to achieve braking and ensure driving safety.

[0033] In some embodiments, the test vehicle further includes a suspension system. The suspension system connects the vehicle body 11 to the connecting shaft and bears the heavy load-bearing and shock-absorbing tasks. The suspension system consists of tandem leaf springs and suspension supports.

[0034] In some embodiments, to ensure the detection accuracy of the road quality inspection mechanism, the frame 10 further includes at least four lifters connected to the vehicle body 11. Along the longitudinal direction of the vehicle body 11, at least two of the at least four lifters are located on one side of the vehicle body 11, and the remaining four lifters are located on the other side of the vehicle body 11.

[0035] When the vehicle body 11 reaches the inspection position, the lifting device is activated, moving towards the ground to raise the vehicle body 11, thus creating a gap between the vehicle body 11 and the ground. The road quality inspection mechanism then conducts the road quality inspection, ensuring its accuracy by preventing the movement of the vehicle body 11 from interfering with the inspection. Upon completion of the road quality inspection, the lifting device is activated again, moving away from the ground to lower the vehicle body 11, allowing the walking assembly 12 to contact the ground and enabling the vehicle body 11 to move.

[0036] In some embodiments, the lifter includes a hydraulic cylinder to achieve the lifting and lowering of the vehicle body 11.

[0037] Combination Figure 4 In some embodiments, in order to enable the hydraulic cylinder and vibrator 50 to operate, the test vehicle further includes a hydraulic pump 60. The hydraulic pump 60 is located on the vehicle body 11 and is connected to the hydraulic cylinder and vibrator 50 so that the hydraulic cylinder and vibrator 50 can operate.

[0038] Combination Figure 2 In some embodiments, the vibrator mounting position has a through hole penetrating the vehicle body 11 for the actuating end of the vibrator 50 to extend out, so that the vibrator 50 can contact the road surface and ensure the road surface quality inspection is carried out.

[0039] Combination Figure 4 In some embodiments, the test vehicle further includes a generator 70 for power supply. The generator 70 is located on the vehicle body 11 and supplies power to all equipment, including a hydraulic pump 60, a vibrator 50, and the measuring system of the road quality inspection mechanism. For example, the generator 70 may be a diesel generator.
