Detailed Implementation

[0028] To better understand the purpose, structure, and function of this utility model, the following detailed description of the intelligent road smoothness measuring device provided by this utility model is provided in conjunction with the accompanying drawings, so that those skilled in the art can better understand this utility model and implement it. However, the embodiments described are not intended to limit this utility model.

[0029] Please see Figures 1 to 6 As shown in the embodiment of this application, a road smoothness intelligent measuring device is provided, including a walking mechanism 100, a detection mechanism 200, a lifting mechanism 300, and a sweeping mechanism 400; the detection mechanism 200 is detachably mounted on the walking mechanism 100; the lifting mechanism 300 is disposed at one end of the walking mechanism 100; the sweeping mechanism 400 is slidably connected to the lifting mechanism 300; the sweeping mechanism 400 includes a dust suction assembly 410, a roller brush 420, and two rotating rods 430; the dust suction assembly 410 and the lifting mechanism 300 are screwed together. The vacuum assembly 410 has a grooved connection, and a locking block 412A is provided on both sides of the vacuum hopper 412 of the vacuum assembly 410; one end of each of the two rotating rods 430 is hinged to both sides of the vacuum hopper 412 of the vacuum assembly 410, and the other end of each of the two rotating rods 430 extends obliquely downward to the side away from the vacuum assembly 410, and is rotatably connected to both ends of the roller brush 420; the rotating rods 430 are locked onto the locking blocks 412A; a first motor 431 for driving the roller brush 420 to rotate is provided at the end of the rotating rod 430 near the roller brush 420.

[0030] Because the device is equipped with a walking mechanism 100, a detection mechanism 200, a lifting mechanism 300, and a sweeping mechanism 400, and the sweeping mechanism 400 is equipped with a dust collection component 410, a roller brush 420, and two rotating rods 430, with a locking block 412A on each side of the dust collection hopper 412 of the dust collection component 410, and a first motor 431 for driving the roller brush 420 to rotate at the end of the rotating rod 430 near the roller brush 420, the device can not only move as a whole through the walking mechanism 100 and measure the road smoothness through the detection mechanism 200, but also sweep away debris on the road surface through the sweeping mechanism 400 and collect the swept garbage or debris, thus avoiding the impact of debris on the smoothness detection and effectively improving the detection accuracy of the intelligent road smoothness measurement device.

[0031] Specifically, a walking mechanism 100 is used as the moving carrier of the entire device to move the intelligent road smoothness measuring device, ensuring continuous operation on different road sections. The detection mechanism 200 is detachably connected to the walking mechanism 100 for easy assembly and disassembly. When the detection mechanism 200 malfunctions or requires calibration, it can be quickly removed from the walking mechanism 100 for processing, ensuring detection accuracy. A lifting mechanism 300 is used to move the sweeping mechanism 400 up and down relative to the road surface, allowing it to move closer to or further away from the road. When road smoothness needs to be measured, the height of the lifting mechanism 300 is lowered to bring the sweeping mechanism 400 closer to the road surface, and the first motor 431 drives the roller brush 420 to rotate clockwise, sweeping debris from the road surface into the dust collection hopper 412 of the dust collection assembly 410. After the inspection is completed, the height of the lifting mechanism 300 is adjusted to move the sweeping mechanism 400 away from the road surface, allowing the intelligent road smoothness measuring device to be moved to the next section to be inspected. A locking block 412A is provided to provide stable support for the connecting rod, securing the roller brush 420 firmly in front of the dust collection hopper 412 of the dust collection assembly 410. This also allows the connecting rod to be easily rotated counterclockwise around the hinge point with the dust collection hopper 412, moving the roller brush 420 upwards for easier cleaning of the interior of the dust collection hopper 412. It should be noted that to improve the stability of the roller brush 420 during use, the connecting rod and locking block 412A can be secured with bolts or other locking devices.

[0032] Furthermore, the vacuuming assembly 410 includes a connecting frame 411, a vacuum hopper 412, a vacuum pipe 413, and a vacuum cleaner 414. One end of the connecting frame 411 is slidably connected to the lifting mechanism 300, and the other end is connected to the vacuum hopper 412. The vacuum pipe 413 is located on the side of the vacuum hopper 412 away from the roller brush 420 and is connected to the dust outlet end of the vacuum hopper 412. The vacuum cleaner 414 is located on the upper end of the walking mechanism 100 near the lifting mechanism 300 and is connected to the dust outlet end of the vacuum pipe 413. The suction power generated by the vacuum cleaner 414 is used to suck in and store the debris and dust collected in the vacuum hopper 412 through the vacuum pipe 413, thus completing the road cleaning.

[0033] In a preferred embodiment, the suction pipe 413 includes a three-way connector 413A and two flexible hoses 413B; the dust inlet end of the three-way connector 413A is connected to the dust outlet end of the suction hopper 412; the dust inlet ends of the two flexible hoses 413B are respectively connected to the two dust outlet ends of the three-way connector 413A, and the dust outlet ends of the two flexible hoses 413B are respectively located on both sides of the vacuum cleaner 414 and are respectively connected to the vacuum cleaner 414.

[0034] Because the suction pipe 413 is equipped with a three-way connecting pipe 413A and two flexible hoses 413B, two suction channels are formed through the distribution and use of the three-way connecting pipe 413A and the two flexible hoses 413B. This not only effectively prevents debris from accumulating and clogging the pipe, improving suction efficiency and ensuring that the debris and dust collected by the dust collection hopper 412 can quickly and smoothly enter the vacuum cleaner 414, but also enhances the flexibility of the suction pipe 413 to adapt to changes in the height of the cleaning mechanism 400.

[0035] In a preferred embodiment, the lifting mechanism 300 includes a vertical slide 310, a threaded rod 320, and a second motor 330. The threaded rod 320 is rotatably connected within the vertical slide 310. The second motor 330 is located at the upper end of the vertical slide 310, and its output end is connected to the threaded rod 320. The end of the connecting frame 411 furthest from the dust collection hopper 412 is located within the vertical slide 310 and threadedly connected to the threaded rod 320. The second motor 330 drives the threaded rod 320 to rotate, thereby causing the connecting frame 411 to move up and down relative to the vertical slide 310, which in turn causes the dust collection hopper 412 and the roller brush 420 to move synchronously.

[0036] In a preferred embodiment, an arc-shaped baffle 412B is provided at the upper end of the dust collection hopper 412. Because the dust collection hopper 412 is equipped with the arc-shaped baffle 412B, it can effectively block debris and dust splashed and raised by the roller brush 420 during cleaning, preventing them from dispersing into the air.

[0037] In a preferred embodiment, the walking mechanism 100 includes a base 110 and two sets of rollers 120; the two sets of rollers 120 are respectively disposed at both ends of the base 110; a mounting groove 111 is formed through the base 110, the mounting groove 111 is located on one side of the vacuum cleaner 414, and two mounting brackets 112 are provided at the lower end of the mounting groove 111; the detection mechanism 200 is embedded in the mounting groove 111 and is detachably connected to the two mounting brackets 112 by bolts. A push rod 114 is provided at the end of the base 110 away from the cleaning mechanism 400. By providing the mounting groove 111 on the base 110 and providing two mounting brackets 112 at the lower end of the mounting groove 111, not only can a stable support be provided for the detection mechanism 200, ensuring the stability of the detection mechanism 200, but also the installation and maintenance of the detection mechanism 200 can be facilitated, improving the disassembly and assembly efficiency of the detection mechanism 200.

[0038] In a preferred embodiment, the detection mechanism 200 includes a detector 210 and a data processor 220; the detector 210 is electrically connected to the lower end of the data processor 220 and is located between two mounting brackets 112. The detector 210 is used to detect road smoothness and transmits the detected information, such as the unevenness of the road surface, to the data processor 220. The data processor 220 analyzes and processes the detection data sent by the detector 210 to obtain relevant results regarding road smoothness.

[0039] In a preferred embodiment, a support frame 113 is inserted into the base 110 near the testing mechanism 200, and a controller 500 is mounted on the support frame 113. The controller 500 is electrically connected to the testing instrument 210, the data processor 220, the first motor 431, and the second motor 330, and is capable of controlling the operation of these components. The display screen of the controller 500 can display the road smoothness results obtained by the data processor 220. By providing a support frame 113 on the base 110 for mounting the controller 500, it facilitates operation and data reading by testing personnel. Furthermore, the support frame 113 is an adjustable-height support frame, allowing testing personnel to adjust its height according to actual needs.

[0040] In this embodiment of the application, a road smoothness intelligent measuring device is first placed on the road to be tested. Then, the controller 500 starts the second motor 330 to lower the height of the sweeping mechanism 400 until the sweeping mechanism 400 is close to the road surface and stops. Next, the first motor 431 is started to drive the roller brush 420 to rotate. At the same time, the detection mechanism 200 and the vacuum cleaner 414 are started. The push rod 114 pushes the road smoothness intelligent measuring device forward to detect the smoothness of the road.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
