Description

Technical Field

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

[0002] Road surface smoothness is a core indicator of road quality, directly impacting driving safety, comfort, and road lifespan. Uneven road surfaces increase rolling resistance, causing additional vehicle vibrations, resulting in a bumpy ride and passenger discomfort. They also accelerate wear and tear on both the road surface and vehicle mechanical components, increasing tire wear and fuel consumption. Statistics show that for every grade decrease in road surface smoothness, fuel consumption may increase by 5%-10%, and tire life may be shortened by 20%-30%. Furthermore, during the rainy season or in low-lying areas, uneven road surfaces are prone to water accumulation, further reducing driving safety. Therefore, scientific and efficient road surface smoothness testing technology is a crucial element in road construction acceptance, maintenance management, and traffic safety assurance.

[0003] Due to the limitations of traditional inspection techniques, which rely on a ruler for testing, requiring manual placement of the ruler on the road surface and measurement of the gap between the ruler and the road surface to determine the flatness, this method is labor-intensive and inefficient, thus having a certain impact. Therefore, there is an urgent need for a traffic road flatness testing device to solve the above problems. Utility Model Content

[0004] To solve the above problems, this utility model provides a traffic road smoothness detection device, which is achieved through the following technical solution.

[0005] A traffic road smoothness detection device includes a fixed frame, wherein the fixed frame has an I-shaped structure, characterized in that a controller is fixedly connected to the top of the fixed frame, and infrared cameras are fixedly connected to both ends of the bottom of the fixed frame, and further includes:

[0006] The limiting posts are two sets that pass through both ends of the fixing frame;

[0007] The caster wheel is suspended from one end of the limiting post;

[0008] A hanger, wherein the hanger is disposed between the limiting post and the caster wheel;

[0009] The laser displacement sensor consists of two sets extending through both ends of the fixed frame, and is used to detect the distance between the fixed frame and the ground.

[0010] Furthermore, one end of the limiting post extends through the center of the top of the hanger, and the limiting post is fixedly connected to the hanger.

[0011] Furthermore, a limit rod is fixedly connected to the top of the omnidirectional wheel, and a slider is fixedly connected to one end of the limit rod extending into the interior of the limit post, and the slider slides in cooperation with the limit post.

[0012] Furthermore, a set of sliding rods is fixedly connected to both ends of the bottom of the hanger. A movable seat is provided at one end of the sliding rod, and a rotating arm is rotatably connected to the bottom of the movable seat. One end of the rotating arm is rotatably connected to a universal wheel. A spring is fixedly connected to the other end of the sliding rod, and one end of the spring is fixedly connected to the movable seat.

[0013] Furthermore, both the laser displacement sensor and the infrared camera are electrically connected to the controller via wires.

[0014] Furthermore, traction lugs are fixedly connected to both ends of the fixed frame.

[0015] The beneficial effects of this utility model are as follows: First, the fixing frame can move on the road via four universal wheels. During the movement, the infrared camera can scan and detect the road surface. The scanned image is analyzed and processed by the controller to detect damage on the road. At the same time, the four cameras can detect the distance between the fixing frame and the road surface in four directions. The road surface flatness is judged based on the detected vertical deviation. The greater the deviation, the worse the road surface flatness. The structure is reasonable, which can reduce labor and improve efficiency. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figure 1-5 As shown, the present invention has the following specific embodiments.

[0032] Example 1

[0033] A traffic road smoothness detection device includes a mounting frame 1, which has an I-shaped structure. A controller 7 is fixedly connected to the top of the mounting frame 1, and infrared cameras 6 are fixedly connected to both ends of the bottom of the mounting frame 1. The device also includes:

[0034] Limiting post 2, which consists of two sets of limiting posts 2 that pass through both ends of the fixing frame 1;

[0035] Caster wheel 3, caster wheel 3 is suspended at one end of limit post 2;

[0036] Hanger 4 is installed between the limit post 2 and the caster wheel 3;

[0037] Laser displacement sensor 5 consists of two sets of laser displacement sensors that pass through both ends of the fixed frame 1, and the laser displacement sensor 5 is used to detect the distance between the fixed frame 1 and the ground.

[0038] Preferably, both the laser displacement sensor 5 and the infrared camera 6 are electrically connected to the controller 7 via wires.

[0039] Preferably, traction lugs 11 are fixedly connected to both ends of the fixing frame 1.

[0040] In this embodiment, as Figure 1 , 2 As shown in Figure 3, the fixed frame 1 can be hoisted and towed by the vehicle through the traction lug 11, so that the fixed frame 1 can move and detect on the road through the casters 3. During the movement detection, the four laser displacement sensors 5 set on the fixed frame 1 can detect the distance from the ground. The set hanger 4 can support the casters 3 and make the limit post 2 have a buffer when moving on the road. When the distance detected by the four laser displacement sensors 5 has a large deviation, it indicates that the road surface is uneven. The larger the deviation, the worse the flatness. The road flatness can be detected quickly.

[0041] Example 2

[0042] The difference from Embodiment 1 is that a lifting structure for the caster wheel 3 is also disclosed:

[0043] One end of the limiting post 2 passes through the center of the top of the hanger 4, and the limiting post 2 is fixedly connected to the hanger 4.

[0044] Preferably, a limiting rod 31 is fixedly connected to the top of the universal wheel 3, and a slider 32 is fixedly connected to one end of the limiting rod 31 that extends into the interior of the limiting post 2, and the slider 32 slides in cooperation with the limiting post 2.

[0045] A set of slide rods 41 are fixedly connected to both ends of the bottom of the hanger 4. A movable seat 42 is provided at one end of the slide rod 41. A rotating arm 43 is rotatably connected to the bottom of the movable seat 42, and one end of the rotating arm 43 is rotatably connected to the universal wheel 3. A spring 44 is fixedly connected to the other end of the slide rod 41, and one end of the spring 44 is fixedly connected to the movable seat 42.

[0046] In this embodiment, as Figure 4 and 5 As shown, the caster wheel 3 can be raised and lowered under the action of external force. The limiting rod 31 fixed on the caster wheel 3 can extend and retract within the limiting post 2, and the slider 32 fixed on the limiting rod 31 slides and engages with the limiting post 2. At the same time, the caster wheel 3 applies pressure to the connected rotating arm 43, which can push the movable seat 42 to slide on the sliding rod 41 and compress the spring 44. After the spring 44 is compressed and stores energy, it can be reset, thereby pushing the suspended caster wheel 3 to reset, so that the four casters wheel 3 on the fixed frame 1 can always move in contact with the road surface. When encountering an uneven road, one or any one of the casters wheel 3 will rise and fall, resulting in a deviation in the height of the four casters wheel 3. The flatness of the road surface can be judged by this deviation.

[0047] The working principle of this utility model:

[0048] When using the device, the fixed frame 1 can move on the road via four casters 3. During the movement, the infrared camera 6 can scan and detect the road surface. The scanned image is analyzed and processed by the controller 7 to detect damage on the road. At the same time, the four 5 can detect the distance between the fixed frame 1 and the road surface in four directions. The road surface flatness is judged based on the detected vertical deviation. The greater the deviation, the worse the road surface flatness. The structure is reasonable, which can reduce labor and improve efficiency.
