Description

Technical Field

[0001] The present invention relates to the technical field of highway construction engineering, and in particular to an intelligent highway engineering compaction test and detection device. Background Art

[0002] Road construction refers to the process of converting a planned road design into a physical road through systematic engineering and technical means in accordance with design requirements. This process primarily includes key steps such as roadbed preparation, pavement paving, drainage facility installation, and traffic sign installation. Furthermore, it is necessary to ensure that the road's load-bearing capacity, smoothness, and durability meet design requirements. Highway engineering compaction testing is a crucial step in road construction quality acceptance.

[0003] Existing highway compaction testing devices generally suffer from insufficient detection accuracy, primarily due to the poor stability of the road surface contact mechanism. The contact components of these conventional devices lack effective self-locking and buffering mechanisms. This can lead to unstable contact pressure during testing due to vehicle vibration or road surface unevenness, compromising the accuracy of test data. Especially during continuous testing over long distances, slight deviations in the contact components can accumulate into significant errors, failing to accurately reflect the actual road surface compaction condition. Therefore, an intelligent highway engineering compaction test device is proposed to address these issues. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides an intelligent highway engineering compaction test detection device to solve the above problems.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] An intelligent highway engineering compaction test device comprises a support frame on which a plurality of highway compaction test assemblies arranged in parallel are mounted;

[0007] Among them, the road compaction inspection component includes an outer shell, a road compaction detection part is installed inside the outer shell, a sliding cylinder is provided at the bottom of the road compaction detection part, a road compaction contact part is provided at the bottom of the sliding cylinder, the sliding cylinder is slidably connected to the inner wall of the outer shell, and a connecting structure is provided between the sliding cylinder and the road compaction contact part.

[0008] Furthermore, the support frame includes a crossbeam, a support rod is installed on the crossbeam, one end of the support rod is connected to the crossbeam, and the other end of the support rod passes through multiple highway compaction test assemblies and is connected to the crossbeam.

[0009] Furthermore, tripods are provided on both sides of the crossbeam for reinforcement, the crossbeam passes through the tripods, and first positioning screws are threadedly connected to the tripods and the crossbeam.

[0010] Furthermore, the road compaction detection component includes a rotating shaft, which is rotatably connected to the support rod, and a contact rod is installed on the rotating shaft. The inner wall of the shell is installed with a plurality of sensors distributed in a circumference.

[0011] Furthermore, a connecting rod is hinged at an eccentric position of the rotating shaft, and a connecting shaft is rotatably connected to the bottom of the connecting rod, and the connecting shaft is fixed to the inner wall of the sliding cylinder.

[0012] Furthermore, the road compacting contact member includes a base plate, and a plurality of contact pads for contacting the ground are installed on the bottom of the base plate.

[0013] Furthermore, a counterweight seat is installed on the top of the base plate, and a counterweight block is snap-connected to the top of the counterweight seat.

[0014] Furthermore, the connection structure includes a connection block and two hinge shafts, both of which are rotatably connected to the inner wall of the sliding cylinder, a first abutment plate and a second abutment plate are mounted on the hinge shaft, the second abutment plate abuts against the connection block, a push rod is slidably connected to the inner wall of the sliding cylinder, one end of the push rod close to the second abutment plate is connected to the abutment block, the other end of the push rod passes through and extends out of the sliding cylinder, and the push rod pushes the second abutment plate through the abutment block;

[0015] Wherein, a torsion spring is provided at the rotation connection portion between the hinge shaft and the sliding cylinder.

[0016] Furthermore, a return spring is sleeved on the push rod, one end of the return spring is connected to the inner wall of the sliding cylinder, and the other end of the return spring is connected to the stop block.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. First of all, the support frame of the device adopts a combination structure of a crossbeam, a tripod and a support rod, which can be firmly installed on the front face of the vehicle for easy mobile detection. The highway compaction test component is composed of a shell, a sliding cylinder, a highway compaction detection component, etc. Among them, the highway compaction contact member cooperates with the connecting structure to sense the unevenness of the road surface in real time, and drives the detection mechanism to work through the up and down movement of the sliding cylinder. The counterweight seat can be loaded with counterweight blocks of different weights so that the contact pad fits fully with the ground to ensure the accuracy of the detection data. The locking structure of the connecting block and the first and second abutment plates, combined with the self-locking function of the torsion spring, enables the sliding cylinder and the detection component to form a stable linkage to avoid loosening or offset during the detection process.

[0020] 2. The device's detection mechanism utilizes a combination of mechanical linkage and sensors to accurately reflect road surface compaction. When the road compaction contact member is displaced due to road surface unevenness, the upward and downward movement of the sliding cylinder drives the rotating shaft through the connecting shaft and connecting rod, causing the contact rod to trigger sensors at different positions. By comparing the initial and final triggered sensor signals, the road surface compaction and smoothness can be quickly determined, improving detection efficiency. The device has a simple structure and is easy to operate, making it suitable for compaction testing in various road conditions. It also has strong environmental adaptability and can be widely used in quality inspection and maintenance inspections of highway projects, providing reliable data support for construction quality assessments.

[0028] In order to make the purpose, features, and advantages of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described below are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0029] Reference Figure 1-5 , an intelligent highway engineering compaction test detection device, comprising a support frame 1, on which a plurality of parallel arranged highway compaction detection components are mounted;

[0030] The road compaction test assembly includes a housing 2, a road compaction detection member 6 is installed inside the housing 2, a sliding cylinder 3 is provided at the bottom of the road compaction detection member 6, a road compaction contact member 4 is provided at the bottom of the sliding cylinder 3, the sliding cylinder 3 is slidably connected to the inner wall of the housing 2, and a connecting structure 5 is provided between the sliding cylinder 3 and the road compaction contact member 4;

[0031] The support frame 1 includes a crossbeam 11, on which a support rod 14 is mounted. One end of the support rod 14 is connected to the crossbeam 11, and the other end of the support rod 14 passes through multiple road compaction test assemblies and is connected to the crossbeam 11.

[0032] Tripods 12 are provided on both sides of the crossbeam 11 for reinforcement. The crossbeam 11 passes through the tripods 12 , and first positioning screws 13 are threadedly connected to the tripods 12 and the crossbeam 11 .

[0033] Specifically, when the device is in use, the support frame 1 can be connected and fixed to the vehicle. When connecting, first fix the crossbeam 11 and the tripod 12, then use the first positioning screw 13 to position the crossbeam 11 and the tripod 12 on the front face of the vehicle, and use the support rod 14 to support multiple road compaction test components;

[0034] The highway compaction test component is a main body composed of an outer shell 2 and a sliding cylinder 3. A highway compaction detection part 6 is added inside the outer shell 2, and the connecting structure 5 and the highway compaction contact part 4 contact the road surface. Because if the paved road surface is uneven, the highway compaction contact part 4 will drive the sliding cylinder 3 to move up and down through the connecting structure 5 when it contacts, thereby driving the highway compaction detection part 6 to detect.

[0035] As an optimized solution, the road compaction detection member 6 includes a rotating shaft 61, which is rotatably connected to the support rod 14, and a contact rod 64 is installed on the rotating shaft 61. A plurality of sensors 65 distributed in a circumference are installed on the inner wall of the housing 2;

[0036] A connecting rod 62 is hinged at an eccentric position of the rotating shaft 61, and a connecting shaft 63 is rotatably connected to the bottom of the connecting rod 62. The connecting shaft 63 is fixed to the inner wall of the sliding cylinder 3;

[0037] The road compacting contact member 4 includes a bottom plate 41 , a plurality of contact pads 44 for contacting the ground are installed at the bottom of the bottom plate 41 , a counterweight seat 43 is installed at the top of the bottom plate 41 , and a counterweight block 42 is snap-connected to the top of the counterweight seat 43 .

[0038] Specifically, during detection, when the road surface is uneven, the road compaction contact member 4 will drive the sliding cylinder 3 to move up and down through the connecting structure 5, thereby driving the rotating shaft 61 to rotate through the connecting shaft 63 and the connecting rod 62, so that the contact rod 64 rotates to contact different sensors 65, and the sensor 65 can be any element on the market that can receive contact information. Finally, based on the initial sensor 65 and the corresponding sensor 65 that is finally contacted, the unevenness of the road surface can be detected, thereby detecting the degree of compaction of the road.

[0039] The connecting structure 5 includes a connecting block 51 and two hinge shafts 55. Both hinge shafts 55 are rotatably connected to the inner wall of the sliding cylinder 3. A first abutment plate 54 and a second abutment plate 56 are installed on the hinge shaft 55. The second abutment plate 56 abuts against the connecting block 51. A push rod 58 is also slidably connected to the inner wall of the sliding cylinder 3. The end of the push rod 58 close to the second abutment plate 56 is connected to a abutment block 57. The other end of the push rod 58 passes through and extends out of the sliding cylinder 3. The push rod 58 pushes the second abutment plate 56 through the abutment block 57.

[0040] Among them, the rotation connection part between the hinge shaft 55 and the sliding cylinder 3 is provided with a torsion spring;

[0041] A return spring 59 is sleeved on the push rod 58. One end of the return spring 59 is connected to the inner wall of the sliding cylinder 3, and the other end of the return spring 59 is connected to the stop block 57.

[0042] A connecting rod 52 is slidably connected to the bottom of the connecting block 51, and the bottom of the connecting rod 52 is connected to the road compaction contact piece 4. A second positioning screw 53 is threadedly connected to the connecting block 51, and the second positioning screw 53 passes through the connecting block 51 and is connected to the corresponding hole on the connecting rod 52.

[0043] Before testing, a counterweight block 42 of corresponding weight is first added to the counterweight seat 43 on the base plate 41 to form a counterweight effect, and finally the contact pad 44 contacts the ground. Then, after removing the second positioning screw 53 as needed, the connecting block 51 is adjusted to the appropriate position, and the second positioning screw 53 is rotated to insert it into the connecting rod 52. However, it is necessary to ensure that the connecting block 51 can be engaged with the first push plate 54, and the torsion spring between the second push plate 56 and the sliding cylinder 3 can allow the first push plate 54, the hinge shaft 55 and the second push plate 56 to always maintain the position as shown in the figure, so that the second push plate 56 can always face and be aligned with the push block 57. In this way, after the connecting block 51 is inserted into the sliding cylinder 3 and passes between the two first push plates 54, the first push plate 54 will be tightly stuck with the bottom of the connecting block 51 and clamp the connecting block 51, so that the first push plate 54, the connecting block 51, the hinge shaft 55 and the sliding cylinder 3 form a whole together.

[0044] Working principle: When the device is in use, the support frame 1 can be connected and fixed to the vehicle. When connecting, first fix the crossbeam 11 and the tripod 12, then use the first positioning screw 13 to position the crossbeam 11 and the tripod 12 with the front face of the vehicle, and use the support rod 14 to support multiple road compaction test components;

[0045] The road compaction test assembly is composed of a housing 2 and a sliding cylinder 3. A road compaction detection member 6 is added to the housing 2. The connecting structure 5 and the road compaction contact member 4 contact the road surface. If the paved road surface is uneven, the road compaction contact member 4 will drive the sliding cylinder 3 to move up and down through the connecting structure 5, thereby driving the road compaction detection member 6 to detect.

[0046] Before testing, a counterweight 42 of corresponding weight is first added to the counterweight seat 43 on the bottom plate 41 to form a counterweight effect, and finally the contact pad 44 contacts the ground. Then, after removing the second positioning screw 53 as needed, the connecting block 51 is adjusted to the appropriate position, and the second positioning screw 53 is rotated to insert it into the connecting rod 52. However, it is necessary to ensure that the connecting block 51 can be engaged with the first push plate 54, and the torsion spring between the second push plate 56 and the sliding cylinder 3 can allow the first push plate 54, the hinge shaft 55 and the second push plate 56 to always maintain the position as shown in the figure, so that the second push plate 56 can always face and align with the push block 57. In this way, after the connecting block 51 is inserted into the sliding cylinder 3 and passes between the two first push plates 54, the first push plate 54 will be tightly stuck with the bottom of the connecting block 51 and clamp the connecting block 51, so that the first push plate 54, the connecting block 51, the hinge shaft 55 and the sliding cylinder 3 form a whole.

[0047] During detection, when the road surface is uneven, the road compaction contact member 4 will drive the sliding cylinder 3 to move up and down through the connecting structure 5, thereby driving the rotating shaft 61 to rotate through the connecting shaft 63 and the connecting rod 62, so that the contact rod 64 rotates to contact different sensors 65, and the sensor 65 can be any element on the market that can receive contact information. Finally, based on the initial sensor 65 and the corresponding sensor 65 finally contacted, the unevenness of the road surface can be detected, thereby detecting the degree of compaction of the road.

[0048] Practical usage of the device:

[0049] First, assemble and secure the crossbeam 11 and tripod 12. Securely mount the combined support frame 1 to the designated location on the front of the vehicle using the first set screws 13. During installation, ensure that the support frame 1 remains perpendicular to the vehicle to prevent tilting that could affect subsequent testing accuracy. After installing the main support frame 1, connect the support rods 14 to the crossbeam 11 to support the subsequent road compaction test assembly. The number of support rods 14 can be adjusted based on actual testing requirements to accommodate simultaneous multi-point testing.

[0050] Assemble the housing 2 and the sliding cylinder 3 to form the test body, and install the road compaction detection member 6 inside the housing 2. After assembly, connect the connecting structure 5 to the road compaction contact member 4 to ensure smooth movement of all components without jamming. Add an appropriate number of counterweight blocks 42 to the counterweight seat 43 on the base plate 41. By adjusting the number of counterweight blocks 42, the contact pad 44 can maintain stable contact with the test road surface. After removing the second positioning screw 53, adjust the connecting block 51 to the appropriate position and re-tighten the second positioning screw 53 to ensure that the connecting block 51 can form a secure engagement with the first abutment plate 54.

[0051] The torsion spring ensures that the second retaining plate 56 is always aligned with and in contact with the retaining block 57. Insert the connecting block 51 correctly into the sliding cylinder 3 and pass it between the two first retaining plates 54. The torsion springs will automatically clamp the first retaining plates 54 against the bottom of the connecting block 51, forming a stable self-locking structure. Ensure that the first retaining plates 54, connecting block 51, hinge shaft 55, and sliding cylinder 3 are fully integrated and free of loose components. This self-locking mechanism ensures that vibration or impact will not cause the connection to fail during testing.

[0052] At the start of testing, the road compaction contact member 4 contacts the road surface to be tested via the connecting structure 5. If the road surface is uneven, the displacement of the road compaction contact member 4 drives the sliding cylinder 3 up and down. The movement of the sliding cylinder 3 is transmitted to the rotating shaft 61 via the connecting shaft 63 and the connecting rod 62, causing the contact rod 64 to rotate. The rotation angle of the contact rod 64 triggers sensors 65 at different positions. By recording the initial and final triggered signals of the sensor 65, the road surface unevenness can be accurately calculated, thereby assessing the degree of road compaction. During the testing process, the number of counterweights 42 can be adjusted according to the actual road conditions to achieve the best test results.
