Description

Technical Field

[0001] This utility model belongs to the field of road inspection technology, and specifically relates to a road smoothness detection device. Background Technology

[0002] Road surface smoothness inspection is a crucial part of road construction and maintenance, and its inspection standards and methods are of great significance for ensuring road quality and driving safety. Smoothness refers to the deviation of the longitudinal unevenness of the road surface, which directly affects the comfort and safety of vehicle driving. Therefore, the formulation of road surface smoothness inspection standards needs to consider the environmental conditions of road use, as well as vehicle speed and load conditions.

[0003] Chinese patent publication number CN220132701U discloses a road smoothness testing device, which includes a connecting rod, a level, a mounting block, a threaded rod, a nut, a limiting block, a mounting rod, a mounting part, a slider, and a laser ranging mechanism. The mounting frame is connected by the connecting rod, and the threaded rods are connected to the mounting frame. Two nuts are connected to two mounting blocks, and the nuts are threadedly engaged with the two threaded rods. Two limiting blocks are provided, each connected to one of the two threaded rods. The two ends of the mounting rod are rotatably connected to the two mounting blocks. The level is connected to the upper end of the mounting rod, the slider is slidably connected to the mounting rod, and the mounting part is connected to the lower end of the slider. A driving assembly is provided inside the mounting part, and the driving assembly is engaged with the mounting rod. The laser ranging mechanism is connected to the lower end of the mounting part. In this invention, the mounting rod used to mount the laser ranging mechanism is kept horizontal, so that the measured distance is not affected by the surrounding road surface, resulting in more accurate measurement results.

[0004] While the aforementioned device can assist in leveling during use, its leveling method primarily relies on manual adjustment of the screws to adjust the height on both sides. This presents certain problems during use. Firstly, it can only adjust the tilt direction on both sides; for example, it can only adjust the tilt direction on the front and rear sides to match the angle. However, when the height on the left and right sides is mismatched, it is clearly unable to adjust flexibly. Furthermore, the manual adjustment method is cumbersome and inconvenient. Therefore, it has certain defects and shortcomings in its practical application and needs improvement. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a road smoothness detection device to solve the problems raised in the background art.

[0006] To achieve the above technical objectives, the technical solution adopted by this utility model is as follows: a road smoothness detection device is provided, including a base, with support legs fixedly installed at both ends of the base, a walking wheel rotatably connected to the outer end of the support legs, an adjustment mechanism fixedly installed on the inner side of the base, and a detection mechanism fixedly installed at the bottom of the adjustment mechanism.

[0007] The detection mechanism includes a frame, an adjustment component fixedly installed at the upper end of the frame, and a leveling ball rotatably connected to the lower end of the frame. An installation component is fixedly installed at the bottom of the leveling ball. A laser rangefinder is mounted on the bottom of the leveling ball via the installation component. This detection mechanism allows for flexible adjustment of the laser rangefinder's tilt angle during use via the adjustment component. The installation component also facilitates quick assembly and disassembly of the laser rangefinder, making the device convenient to use.

[0008] The adjustment mechanism includes a slide groove located in the middle of the base. A lead screw is rotatably connected inside the slide groove, and a slider is threaded onto the outer surface of the lead screw. The top of the frame and the bottom of the slider are fixedly connected. A first motor is fixedly installed on one side of the base, and the output end of the first motor is fixedly connected to one end of the lead screw. By setting the adjustment mechanism, the lateral displacement of the laser rangefinder can be adjusted by starting the first motor during use, thereby improving the overall detection convenience of the device.

[0009] The adjustment assembly includes an electric push rod, which is fixedly installed in the top center of the frame. A second motor is fixedly installed at the bottom output end of the electric push rod, and a concave seat is fixedly installed at the bottom output end of the second motor. A third motor is fixedly installed on one side of the concave seat, and an adjustment wheel is fixedly installed through the output end of the third motor and connected to the inner side of the concave seat. By setting up the adjustment assembly, during use, the second motor can be started to drive the concave seat to rotate, and at the same time, the electric push rod pushes the adjustment wheel to fit against the top of the leveling ball, which can flexibly adjust the rotation of the laser rangefinder and improve the overall adjustment convenience of the device.

[0010] The mounting assembly includes a square frame, which is fixedly installed on the bottom of the leveling ball. Both sides of the square frame are threaded with hand-tightening screws. The upper end of the laser rangefinder is inserted into the inside of the square frame. The inner end of the hand-tightening screw passes through the square frame and is fitted and connected to the upper ends of both sides of the laser rangefinder. By setting up the mounting assembly, the laser rangefinder inserted into the square frame can be fitted and fixed by turning the hand-tightening screw during use.

[0011] An adjustment knob is fixedly installed on the outer end of the hand-tightening screw, and anti-slip protrusions are fixedly connected at equal intervals on the outer surface of the adjustment knob; by setting the adjustment knob, the device as a whole can have strong stability during use.

[0012] The laser rangefinder has a balance block fixedly installed on both sides, and a level is fixedly installed on the other two sides of the frame. By setting the balance block and the level, the horizontal level can be quickly detected by observing the level during use. The balance block can improve the balance performance of the laser rangefinder.

[0013] A handrail is fixedly installed on the middle of one side of the base, and a handrail frame is fixedly installed on the outer end of the handrail. By setting the handrail and the handrail frame together, the handrail frame can be moved by holding the handrail during use, which facilitates the flexible adjustment and use of this device.

[0014] The beneficial effects of this utility model are as follows: By setting an adjustment mechanism, the device can drive a lead screw via a first motor to make the slider slide within the groove, thereby flexibly adjusting the lateral displacement and horizontal position of the laser rangefinder. Simultaneously, the leveling ball hinge balance block at the bottom of the frame can automatically adjust the center of gravity of the laser rangefinder, ensuring it remains balanced under various tilt conditions without manual leveling, making it convenient and adaptable. By setting an adjustment component, the device can easily adjust the tilt angle of the laser rangefinder. When a specific angle detection is required, the electric push rod is activated to lower the concave seat, causing the adjusting wheel to engage with the leveling ball. Then, a third motor drives the adjusting wheel to rotate, achieving longitudinal rotation of the leveling ball, thereby adjusting the longitudinal angle of the laser rangefinder. Simultaneously, a second motor can drive the leveling ball to rotate laterally, further precisely adjusting the tilt angle of the laser rangefinder. This design enables the device to automatically and accurately adjust the tilt angle of the laser rangefinder, improving the convenience of adaptive adjustment. Attached Figure Description

[0020] like Figure 1-4 As shown, a road smoothness detection device according to this embodiment includes a base 1. Support legs 2 are fixedly installed on both sides and the front and rear ends of the base 1. The outer ends of the support legs 2 are rotatably connected to the wheels 4. An adjustment mechanism 3 is fixedly installed on the inner side of the base 1. A detection mechanism 5 is fixedly installed at the bottom of the adjustment mechanism 3. The detection mechanism 5 includes a frame 51. An adjustment component 52 is fixedly installed on the upper end of the inner side of the frame 51. A leveling ball 53 is rotatably connected to the lower end of the inner side of the frame 51. An installation component 55 is fixedly installed on the bottom of the leveling ball 53. A laser rangefinder 8 is installed on the bottom of the leveling ball 53 through the installation component 55. Through the detection mechanism 5, the device can be adjusted flexibly during use by adjusting the laser rangefinder 8 with the assistance of the adjustment component 52. At the same time, the installation component 55 allows for quick installation and removal of the laser rangefinder 8, making the device convenient to use.

[0021] like Figure 1 , 2 As shown, the adjustment mechanism 3 includes a slide groove 31, which is located in the middle of the base 1. A lead screw 32 is rotatably connected inside the slide groove 31, and a slider 33 is threadedly connected to the outer surface of the lead screw 32. The top of the frame 51 and the bottom of the slider 33 are fixedly connected. A first motor 34 is fixedly installed on one side of the base 1. The output end of the first motor 34 is fixedly connected to one end of the lead screw 32. By setting the adjustment mechanism 3, the device can be used by starting the first motor 34 and driving the lead screw 32 to rotate, which can help push the slider 33 to slide inside the slide groove 31. The lateral displacement of the laser rangefinder 8 can be adjusted by sliding the slider 33, which can improve the overall detection convenience of the device.

[0022] like Figure 1 , 2As shown, the adjustment assembly 52 includes an electric push rod 521, which is fixedly installed in the top center of the frame 51. A second motor 522 is fixedly installed at the bottom output end of the electric push rod 521. A concave seat 523 is fixedly installed at the bottom output end of the second motor 522. A third motor 524 is fixedly installed on one side of the concave seat 523. An adjustment wheel 525 is fixedly installed through the concave seat 523 at the output end of the third motor 524. The adjustment wheel 525 is rotatably connected to the inner side of the concave seat 523. By setting the adjustment assembly 52, the device can be adjusted during use. By starting the second motor 522, the concave seat 523 is driven to rotate. At the same time, the electric push rod 521 pushes the adjusting wheel 525 to fit against the top of the leveling ball 53, which can flexibly adjust the rotation of the laser rangefinder 8. Then, by running the third motor 524, the adjusting wheel 525 can be driven to rotate further, which can help adjust the leveling ball 53 to rotate to the other side. This allows the device to be adapted to adjust the laser rangefinder 8 to different angles during use, which can improve the overall adjustment convenience of the device.

[0023] like Figure 3 , 4 As shown, the mounting component 55 includes a frame 551, which is fixedly installed on the bottom of the leveling ball 53. Both sides of the frame 551 are threaded with hand-tightening screws 552. The upper end of the laser rangefinder 8 is inserted into the inside of the frame 551. The inner end of the hand-tightening screw 552 passes through the frame 551 and fits snugly to the upper ends of both sides of the laser rangefinder 8. By setting up the mounting component 55, during the use of this device, the laser rangefinder 8 inserted into the frame 551 can be fitted and fixed by twisting the hand-tightening screw 552. When disassembly is required, the laser rangefinder 8 can be quickly removed by loosening the hand-tightening screw 552, which is convenient for flexible disassembly, assembly, inspection and maintenance.

[0024] like Figure 3 , 4 As shown, an adjustment knob 553 is fixedly installed on the outer end of the hand-tightening screw 552. Anti-slip protrusions are fixedly connected at equal intervals on the outer surface of the adjustment knob 553. By setting the adjustment knob 553, the hand-tightening screw 552 can be quickly disassembled and repaired by turning the adjustment knob 553 during use. The anti-slip protrusions can further improve the friction of the outer surface of the hand-tightening screw 552, so that the whole device can have strong stability.

[0025] like Figure 3 , 4As shown, a balance block 56 is fixedly installed on both sides of the laser rangefinder 8, and a level 54 is fixedly installed on the other two sides of the frame 551. By setting the balance block 56 and the level 54, the horizontality can be quickly detected by observing the level 54 during use. Setting the balance block 56 can improve the balance performance of the laser rangefinder 8, so that the whole device can have better stability.

[0026] like Figure 3 , 4 As shown, a handrail 6 is fixedly installed on the middle of one side of the base 1, and a handrail frame 7 is fixedly installed on the outer end of the handrail 6. By setting the handrail 6 in conjunction with the handrail frame 7, the handrail frame 7 can be moved by holding the handrail 6 during use, which facilitates the flexible adjustment and use of this device and improves the overall ease of adjustment and use of this device.

[0027] Operating Principle and Advantages: By setting the adjustment mechanism 3, the device can be used during operation by starting the first motor 34. The first motor 34 drives the lead screw 32 to move the slider 33 inside the slide groove 31, which can assist in adjusting the lateral displacement of the laser rangefinder 8. By adjusting the lateral displacement of the laser rangefinder 8, the horizontal position of the laser rangefinder 8 can be flexibly adjusted. It can be flexibly adapted and adjusted. During the detection process, since the bottom of the frame 51 adopts the leveling ball 53 and ball hinge balance block 56, the balance block 56 provides gravity during the lateral displacement of the laser rangefinder 8, keeping the center of gravity of the laser rangefinder 8 centered. When the base 1 tilts, the leveling ball 53 rotates adaptively, which can automatically keep the laser rangefinder 8 in a balanced state. This allows the device to automatically level during use, which can improve the leveling convenience of the device during use. There is no need for manual leveling, making it more convenient to use and highly adaptable. By setting the adjustment component 52, the device can be used... During the process, if a specific angle is required for detection, the electric push rod 521 can be activated to push the concave seat 523 downward. The adjusting wheel 525 on the inner side of the concave seat 523 will then fit against the outer surface of the leveling ball 53. At this time, the leveling ball 53 can be positioned by the contact between the adjusting wheel 525 and the leveling ball 53. Then, by activating the third motor 524 to drive the adjusting wheel 525 to rotate, the longitudinal rotation of the leveling ball 53 can be assisted by the rotation of the adjusting wheel 525. At this time, the longitudinal rotation of the laser rangefinder 8 can be adjusted. Simultaneously, the second motor 522 can be activated to drive the leveling ball 53 to rotate laterally. The rotation of the leveling ball 53 can assist in adjusting the rotation of the laser rangefinder 8. It can be seen that this device can adaptively adjust the rotation of the leveling ball 53 by cooperating with the second motor 522 and the third motor 524, thereby achieving automatic and precise adjustment of the tilt direction of the laser rangefinder 8. This allows the device to flexibly and accurately adjust the tilt direction of the laser rangefinder 8 during use, further improving the adaptability and ease of adjustment of the device.
