Abstract
Description
Technical Field
[0001] This utility model belongs to the field of asphalt performance testing technology, specifically relating to a portable highway asphalt performance testing device. Background Technology
[0002] In highway construction and maintenance, the quality of asphalt paving directly affects the service life of the road and driving safety, while the asphalt height at the road edge is a key indicator for measuring the smoothness and compliance of asphalt paving.
[0003] The detection of asphalt height at the edge of highways generally adopts distance sensor-based measurement technology. The specific operation procedure is as follows: the operator first uses the distance sensor at the same horizontal height to determine the position of the detection base point and establish a benchmark reference. Then, while keeping the measurement sensor at the same height, the asphalt surface at the edge of the highway is measured one by one.
[0004] Currently, when measuring the asphalt height at the edge of a highway, operators need to repeatedly bend over to adjust the sensor position during multiple measurements. This frequent manual adjustment of the measurement position leads to low detection efficiency and high labor intensity for the operators. Utility Model Content
[0005] To solve the above-mentioned technical problems, the present invention provides a portable highway asphalt performance testing mechanism, characterized in that it includes a support plate and an adjustment assembly. A protective box is fixedly connected to the upper surface of the support plate. The adjustment assembly includes a motor, a first rotating shaft, a half-bevel gear, a first bevel gear, a second bevel gear, and a second rotating shaft. The side surface of the first bevel gear meshes with the half-bevel gear, and the side surface of the second bevel gear meshes with the half-bevel gear. A rotating plate is fixedly connected to the upper surface of the second rotating shaft, and a distance sensor is fixedly connected to the lower surface of the rotating plate.
[0006] Through the above technical solution, the rotating plate can be adjusted in both directions by adjusting the components. This structure can quickly measure the base surface of the distance sensor and then rotate the distance sensor to the asphalt side of the road for direct measurement. During the process, there is no need for the operator to manually adjust the position of the distance sensor. At the same time, the flexible adjustment of the distance sensor angle can easily achieve quick switching measurement of the left or right edge of the road. There is no need to frequently move the detection mechanism or change the user's own position during the process. This structure improves the efficiency of detection.
[0007] The present invention is further configured such that the output end of the motor is fixedly connected to the first rotating shaft, and the side surface of the first rotating shaft is fixedly connected to the half-bevel gear.
[0008] The above technical solution, which uses a rigid connection between the motor output shaft and the first rotating shaft, ensures that power can be transmitted continuously and stably during long-term, high-intensity testing work, thus ensuring the smooth progress of the testing work.
[0009] The present invention is further configured such that the side surface of the second rotating shaft is fixedly connected to the first bevel gear, and the side surface of the second rotating shaft is fixedly connected to the second bevel gear.
[0010] The above technical solution clarifies the linkage relationship between the second rotating shaft, the first bevel gear, and the second bevel gear. The starting motor drives the first rotating shaft to rotate, and the rotating plate reciprocates under the action of the half gear, the first bevel gear, and the second bevel gear. This allows for quick adjustment of the distance sensor's position. At the same time, the action of the half bevel gear ensures the accuracy and repeatability of each adjustment of the second rotating shaft's angle, providing a stable and reliable measurement basis for highway asphalt height detection.
[0011] The present invention is further configured such that the protective box has an internal cavity, and the motor, the first rotating shaft, the half bevel gear, the first bevel gear, and the second bevel gear are all disposed inside the cavity.
[0012] Through the above technical solution, the protective box provides protection for the internal components. This structure can effectively prevent external pollutants such as dust and rainwater from entering the precision gear transmission, thereby extending the service life of the internal components.
[0013] The present invention is further configured such that the bottom inner wall of the cavity is fixedly connected to the motor, a first bearing is fixedly connected to the bottom inner wall of the cavity, the inner surface of the first bearing is fixedly connected to the second rotating shaft, an opening is provided inside the protective box, a second bearing is fixedly connected to the inner surface of the opening, and the inner surface of the second bearing is fixedly connected to the second rotating shaft.
[0014] The above technical solution clarifies the fixed connection method between the inner wall of the cavity bottom and the motor, as well as the supporting role of the first bearing and the second bearing on the second rotating shaft, ensuring the stability of the rotation of the second rotating shaft.
[0015] The present invention is further configured such that a fixing block is fixedly connected to the upper surface of the support plate, a connecting rod is fixedly connected to the side surface of the fixing block, and a fixing plate is fixedly connected to the end of the connecting rod away from the fixing block.
[0016] Through the above technical solution, the fixing block and connecting rod provide support for the fixing plate.
[0017] The present invention is further configured such that a controller is fixedly connected to the upper surface of the fixing plate, a handle is fixedly connected to the side surface of the fixing plate, and a moving wheel is provided on the lower surface of the support plate.
[0018] The above technical solution clarifies the installation positions of the upper surface controller and side surface handle on the fixed plate, as well as the setting of the moving wheels on the lower surface of the support plate. In actual use, this structure is very convenient to move through human-computer interaction, making it easy to quickly detect the asphalt thickness at different locations. It is also very convenient to move the device.
[0019] The beneficial effects of this utility model are as follows:
[0020] By incorporating components such as an adjustment mechanism, a rotating plate, and a distance sensor, the distance sensor, after completing the base surface measurement, can be quickly rotated to the asphalt side of the road for direct measurement under the action of the adjustment mechanism. During the process, there is no need for operators to manually adjust the position of the distance sensor, and the detection can be completed without operators frequently bending over, reducing the labor intensity of operators. Furthermore, the flexible adjustment of the distance sensor angle can easily achieve rapid switching between measurements on the left or right edge of the road, without the need to frequently move the detection mechanism or change the operator's own position. This structure improves the efficiency of the detection. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0027] like Figures 1-4 As shown, a portable highway asphalt performance testing mechanism according to this embodiment includes a support plate 1 and an adjustment assembly 4. A protective box 2 is fixedly connected to the upper surface of the support plate 1. The adjustment assembly 4 includes a motor 401, a first rotating shaft 402, a half-bevel gear 403, a first bevel gear 404, a second bevel gear 405, and a second rotating shaft 406. The bottom inner wall of the cavity 3 is fixedly connected to the motor 401, increasing the stability of the structural connection. The output end of the motor 401 is fixedly connected to the first rotating shaft 402. The side surface of the first rotating shaft 402 is fixedly connected to the half-bevel gear 403. The side surface of the first bevel gear 404 meshes with the half-bevel gear 403. The second bevel gear... The side surface of 405 meshes with the half-bevel gear 403. The side surface of the second rotating shaft 406 is fixedly connected to the first bevel gear 404, and the side surface of the second rotating shaft 406 is fixedly connected to the second bevel gear 405. A rotating plate 5 is fixedly connected to the upper surface of the second rotating shaft 406, and a distance sensor 6 is fixedly connected to the lower surface of the rotating plate 5. When the motor 401 is started, the output end of the motor 401 rotates, driving the first rotating shaft 402 and the half-bevel gear 403 to rotate. Under the action of the first bevel gear 404 and the second bevel gear 405, the second rotating shaft 406, the rotating plate 5, and the distance sensor 6 can reciprocate. In actual use, the detection mechanism is placed on the detection... On one side of the asphalt road, after rotating the distance sensor 6 to the base surface for measurement, the motor 401 is started. Under the action of the first rotating shaft 402, the half-bevel gear 403, the first bevel gear 404, and the second bevel gear 405, the second rotating shaft 406 and the distance sensor 6 are driven to rotate to the side of the asphalt road. The thickness of the road can be measured through the distance sensor 6. During the process, there is no need for operators to bend over or make manual adjustments. This structure can complete a large number of asphalt thickness detection tasks in a short time. It is suitable for large-scale road maintenance and inspection scenarios, greatly improving work efficiency and avoiding frequent bending over, effectively reducing labor intensity. This design reduces the risk of occupational injury. When the testing mechanism is placed on one side of the road to be tested, the thickness of the road to be tested may be on the left or right side of the testing mechanism. By starting the motor 401, the second rotating shaft 406 and the distance sensor 6 are driven to rotate under the action of the first rotating shaft 402, the half bevel gear 403, the first bevel gear 404, and the second bevel gear 405. This allows for adjustment of the position of the distance sensor 6, facilitating quick switching of its position. During the process, the operator does not need to move the entire testing mechanism or their own position, avoiding the time wasted due to frequent movement of equipment or personnel. At the same time, this structure is simple to operate and convenient to use.
[0028] The protective box 2 has an internal cavity 3. The motor 401, first shaft 402, half-bevel gear 403, first bevel gear 404, and second bevel gear 405 are all housed within this cavity 3. The sealed cavity 3 of the protective box 2 meets IP65 protection standards, effectively isolating it from external pollutants such as dust, rainwater, and oil. In the complex environment of highway construction and maintenance, dust particles easily cause gear wear, and rainwater and oil can corrode metal components. This structure ensures that the motor 401, gear set, and other components remain in a clean and dry environment, thus extending the service life of the internal components. A first bearing 7 is fixedly connected to the bottom inner wall of the cavity 3, and the inner surface of the first bearing 7 is fixedly connected to the second shaft 406. The protective box 2 also has an opening 8, and a second bearing 9 is fixedly connected to the inner surface of the opening 8. The inner surface of the second bearing 9 is fixedly connected to the second shaft 406. The first bearing 7 and the second bearing 9 provide support and fixation for the second shaft 406, forming a support structure for the second shaft 406. The precise positioning and support at the top and bottom points allow the second rotating shaft 406 to rotate more stably and flexibly, thereby ensuring that the rotating plate 5 rotates more stably.
[0029] A fixing block 10 is fixedly connected to the upper surface of the support plate 1, and a connecting rod 11 is fixedly connected to the side surface of the fixing block 10. The fixing block 10 and the connecting rod 11 provide support for the fixing plate 12, the controller 13, and the handle 14. The end of the connecting rod 11 away from the fixing block 10 is fixedly connected to the fixing plate 12. The controller 13 is fixedly connected to the upper surface of the fixing plate 12. A display screen is provided on the side surface of the controller 13. The motor 401, the distance sensor 6, and the display screen are all electrically connected to the controller 13. A handle 14 is fixedly connected to the side surface of the fixing plate 12. The handle 14 allows the operator to easily push the testing equipment, making the testing process more continuous and smooth. The thickness of asphalt at different locations can be tested without the operator having to bend over frequently. The lower surface of the support plate 1 is provided with a moving wheel 15, which allows the testing mechanism to be moved easily.
[0030] The working principle of this utility model is as follows: In use, the detection mechanism is placed on one side of the asphalt road surface being tested. The motor 401 is started, and its output rotates, driving the first rotating shaft 402 and the half-bevel gear 403 to rotate. Under the action of the first bevel gear 404 and the second bevel gear 405, the second rotating shaft 406, the rotating plate 5, and the distance sensor 6 can reciprocate. After rotating the distance sensor 6 to one side of the base surface for measurement, the motor 401 is started again. Under the action of the first rotating shaft 402, the half-bevel gear 403, the first bevel gear 404, and the second bevel gear 405, the second rotating shaft 406 and the distance sensor 6 are rotated to one side of the asphalt road surface. The thickness of the road surface can be measured through the distance sensor 6. The measurement data can be viewed on the display screen on the controller 13. By pushing the handle 14, the operator can detect the asphalt thickness at different locations. Before use, the detection mechanism should be placed in position. The road surface to be tested may be on the left or right side of the detection mechanism. By starting the motor 401, the second rotating shaft 406 and the distance sensor 6 are driven to rotate under the action of the first rotating shaft 402, the half bevel gear 403, the first bevel gear 404, and the second bevel gear 405. This allows the use position of the distance sensor 6 to be adjusted, facilitating quick switching of the use position of the distance sensor 6. During the process, the operator does not need to move the entire detection mechanism or move their own position, thus facilitating quick measurement of the road asphalt height after measuring the base surface.
