Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of road surface detection, and particularly refers to a road surface quality detection device for highway engineering. Background Technique
[0002] The inspection and acceptance of highway engineering road surfaces include: road surface flatness detection to ensure comfortable and safe driving; road surface thickness measurement to verify the stable and durable structure; road surface quality detection to ensure that the material quality meets the standards; road surface marking inspection to ensure clear and standardized navigation; road surface skid resistance detection to improve driving safety. Through these detections, the road surface quality and safety can be comprehensively evaluated. Among them, the texture depth is an important inspection object.
[0003] In road construction, there are indeed some problems with the method of laying fine sand and then collecting it to measure the texture depth of the road surface. First of all, the process of laying sand may lead to unevenness because the sand may accumulate or be thin during the laying process, which will affect the accuracy of the final measurement. Secondly, sampling may also encounter difficulties because when sampling the sand after laying, it is very likely to touch the surrounding sand, so the sample obtained may not be pure enough, which will also affect the measurement accuracy. Content of the Utility Model
[0004] In order to solve the above various problems, the utility model proposes a road surface quality detection device for highway engineering that is convenient for evenly laying sand, can prevent the influence of surrounding sand from generating errors, and has accurate detection results.
[0005] In order to solve the above technical problems, the technical solution proposed by the utility model is: a road surface quality detection device for highway engineering, including a sampling outer cylinder, a sampling inner cylinder and a quantitative ring. The sampling inner cylinder is slidably arranged inside the sampling outer cylinder. A number of thin rods are connected below the sampling inner cylinder. One end of a motor is connected above the sampling inner cylinder through a fixing plate, and a rotating rod is connected to the end of the motor. A cleaning frame is connected to the other end of the rotating rod. A motor two is connected to the lower end of the electric push rod, and a push plate is connected to the end of the motor two. The diameter of the quantitative ring is smaller than the diameter of the sampling inner cylinder.
[0006] Furthermore, a number of sliding strips are connected to the inner wall of the sampling outer cylinder, and a sliding groove matching the sliding strips is arranged on the outer wall of the sampling inner cylinder.
[0007] Based on the above features, the cooperation of the sliding strips and the sliding grooves can ensure the stable up and down sliding of the sampling outer cylinder relative to the sampling inner cylinder, avoid the rotation between them leading to the flow of sand, and thus ensure the accuracy of the detection results.
[0008] Furthermore, the cleaning frame is connected to the rotating rod through screws.
[0009] Based on the above features, the convenient disassembly enables the sampling outer cylinder to smoothly move downward until it contacts the ground.
[0010] Furthermore, the lower end of the cleaning frame is flush with the lower end of the thin rod, and the side of the cleaning frame close to the sampling inner cylinder is flush with the outer side wall of the sampling inner cylinder.
[0011] Based on the above features, the sand on the outer part of the sampling inner cylinder can be effectively and thoroughly cleaned, thereby preventing sand from entering the sampling area and affecting the test results.
[0012] Furthermore, handles are symmetrically connected to both sides of the quantitative ring.
[0013] Based on the above features, it is convenient and stable to pick up and place the quantitative ring, ensuring the unity of the sampling area and preventing deviation in the test results caused by its displacement during the sampling process.
[0014] Furthermore, the lower end of the side wall of the quantitative ring is a thin plate.
[0015] Based on the above features, it is convenient to accurately clean the sand outside the quantitative ring, ensuring the accuracy of the test results.
[0016] The advantages of the present utility model compared with the prior art are as follows: The push plate can rotate and gradually move downward under the drive of the electric push rod and the second motor, which is convenient for gradually and evenly spreading the sand on the inner side of the sampling inner cylinder flat, and pushing the excess sand out through the gaps between the thin rods. The operation is convenient and practical. At the same time, during the above process, the cleaning frame can continue to sweep and spread the pushed sand outward, effectively avoiding the mixing of the surrounding sand and the sand within the sampling range during sampling, resulting in errors. The test results are accurate and reliable. The size of the quantitative ring is fixed, which is convenient for quantitative sampling, facilitating the calculation of the test results and ensuring the accuracy of the results.

The sampling inner cylinder 2 is slidably arranged inside the sampling outer cylinder 1. A plurality of sliding strips are connected and arranged on the inner wall of the sampling outer cylinder 1. A chute 12 for matching the sliding strips is arranged on the outer wall of the sampling inner cylinder 2. The cooperation of the sliding strips and the chute 12 can ensure the stable up and down sliding of the sampling outer cylinder 1 relative to the sampling inner cylinder 2, avoiding the mutual rotation between them and the flow of sand, and thus ensuring the accuracy of the detection result.
[0025] Combined with the attached Figure 1 and the attached Figure 3 and the attached Figure 4 A plurality of thin rods 4 are connected and arranged below the sampling inner cylinder 2. A motor 1 6 and an electric push rod 7 are respectively connected and arranged above the sampling inner cylinder 2 through a fixed plate 5. A rotating rod 8 is connected to the end of the motor 1 6. The other end of the rotating rod 8 is connected to a cleaning frame 9. The cleaning frame 9 is connected to the rotating rod 8 by screws, which is convenient for disassembly so that the sampling outer cylinder 1 can smoothly move down to contact the ground. The lower end of the cleaning frame 9 is flush with the lower end of the thin rod 4, and the side of the cleaning frame 9 close to the sampling inner cylinder 2 is flush with the outer side wall of the sampling inner cylinder 2, which can effectively and thoroughly clean the sand on the outer part of the sampling inner cylinder 2, and thus prevent the sand from entering the sampling area and affecting the detection result.
[0026] Combined with the attached Figure 1 and the attached Figure 2 and the attached Figure 5 The lower end of the electric push rod 7 is connected with a motor 2 10, and the end of the motor 2 10 is connected with a push plate 11. The diameter of the quantitative ring 3 is smaller than the diameter of the sampling inner cylinder 2.

The second motor 10 drives the push plate 11 to rotate, and at the same time the electric push rod 7 drives the push plate 11 to descend evenly. The push plate 11 pushes the sand to move outward of the sampling inner cylinder 2, and the sand moves out through the gaps between the thin rods 4. At the same time, the first motor 6 drives the cleaning frame 9 to move through the rotating rod 8, and the cleaning frame 9 further sweeps the moved sand to the periphery until only the sand in the sampling inner cylinder 2 remains in the road surface depression and there is basically no sand within the cleaning area of the cleaning frame 9. Remove the cleaning frame 9, lower the sampling outer cylinder 1 so that its lower end contacts the ground, and clean the ground outside the sampling outer cylinder 1 again until there is no sand.
