Description

Technical Field

[0001] The utility model relates to the technical field of road detection equipment, and in particular to a road surface quality detection device for traffic engineering. Background Art

[0002] With the rapid development of transportation infrastructure construction, ensuring the quality and safety of roads has become particularly important. Road quality not only affects driving safety and comfort, but is also directly related to vehicle fuel efficiency and road service life.

[0003] Traditional methods that rely on manual visual inspection or use simple tools for measurement are difficult to provide high-precision data, and are not accurate enough in detecting fine cracks and flatness changes. In addition, relying on manpower to check the road condition section by section is time-consuming and laborious, and cannot meet the needs of modern traffic engineering for quickly obtaining large-area road condition information. Before conducting road surface inspection, it is usually necessary to clean up the surface such as dust, cigarette butts and other debris to avoid interfering with the inspection results, which further increases the intensity of manual labor. Therefore, we propose a traffic engineering road quality inspection device to overcome the above defects. Utility Model Content

[0008] Preferably, a mounting frame is fixedly installed at the bottom of the casing, and two electric push rods are symmetrically fixed on the mounting frame. The push rods of the electric push rods are commonly connected to a mounting plate, and a plurality of fans are integrated and installed inside the mounting plate.

[0011] The utility model has the following advantages:

[0012] 1. By combining a camera and a 3D laser scanning module, the utility model can capture high-definition images of the road surface and details such as tiny cracks and depressions, providing higher detection accuracy than traditional methods.

Selected positional descriptions in the description, such as top, bottom, lateral, etc., also refer to the directly described and shown figures and are transferred to the new positions in the case of a change in position.

[0021] A traffic engineering pavement quality detection device, such as Figure 1-Figure 4 As shown, it includes a casing 1, which is a mounting carrier of the detection device. A plate body protruding forward is provided on the top of the detection end face of the casing 1; it also includes a bracket 3, a universal wheel 4, a camera 5, an articulated frame 6 and a three-dimensional laser scanning module 7. Brackets 3 are symmetrically fixedly installed on both sides of the bottom of the casing 1, universal wheels 4 are installed at the bottom corners of the bracket 3, and brakes are built in the universal wheels 4. A camera 5 is installed on the plate body protruding forward on the top of the casing 1, and the lens of the camera 5 is tilted downward. The camera 5 is used to capture high-definition images of the road surface, and identify cracks, potholes and other types of damage on the road surface through image processing technology. An articulated frame 6 is fixedly connected to a side surface of the casing 1 close to the camera 5, and a three-dimensional laser scanning module 7 is also provided on the plate body protruding forward on the top. The three-dimensional laser scanning module 7 is rotatably assembled on the front side of the casing 1 through the articulated frame 6. The camera 5 and the three-dimensional laser scanning module 7 are arranged side by side. The three-dimensional laser scanning module 7 is used to more accurately detect tiny cracks and depressions on the road surface, automatically collect high-precision data on the road surface, reduce manual intervention, and improve work efficiency.

[0022] like Figure 1As shown, a handle 2 is fixedly installed on the rear side of the housing 1 away from the camera 5 and the three-dimensional laser scanning module 7. An anti-slip pad 21 is provided on the grip of the handle 2. By holding the handle 2, the entire detection device can be conveniently controlled to move forward and detect the road quality.

[0023] like Figure 2 and Figure 3 As shown, a motor 8 is also included. The motor 8 is fixedly installed at the place where the three-dimensional laser scanning module 7 is installed on the articulated frame 6. The output shaft of the motor 8 is connected to the rotating shaft of the three-dimensional laser scanning module 7. The motor 8 is used to drive the three-dimensional laser scanning module 7 to perform rotation detection, so that the three-dimensional laser scanning module 7 can adapt to the efficient detection of roads with different slopes.

[0024] like Figure 1 and Figure 4 As shown, a mounting frame 9 is fixedly installed at the bottom of the casing 1, and two electric push rods 10 are symmetrically fixed on the mounting frame 9. The push rods of the electric push rods 10 are commonly connected to a mounting plate 11, and a plurality of fans 12 are integrated and installed inside the mounting plate 11. The fans 12 are tilted downward toward the road surface where the device is pushed, and dust, garbage and other impurities on the road surface to be inspected are blown away in advance. The fans 12 are adjusted in conjunction with the electric push rods 10 to clean the road surface at different distances, thereby improving the detection accuracy of the subsequent camera 5 and the three-dimensional laser scanning module 7 on the road quality.

The universal wheel 4 at the bottom of the device has a built-in brake, which can be locked in position as needed to ensure that the device remains stable during the inspection process. During the movement, the electric push rod 10 on the mounting frame 9 at the bottom of the housing 1 can adjust the extension distance of the mounting plate 11 according to the road surface conditions, so that the fan 12 integrated on the mounting plate 11 blows downward on the road surface at the optimal distance and angle to remove impurities such as dust and garbage, and provide a clean road surface environment for subsequent inspections. When the device starts working, the front camera 5 will capture high-definition images of the road surface, and these images will be processed through image processing technology. To identify cracks, potholes and other types of damage on the road surface. At the same time, the three-dimensional laser scanning module 7 located next to the camera 5 and connected to the housing 1 through the hinged frame 6 also starts to operate. The motor 8 drives the module to rotate so that it can adapt to roads of different slopes and accurately detect tiny cracks and depressions on the road surface. When the device moves forward, the spring 13 between the bracket 3 and the universal wheel 4 can absorb the vibration generated during the movement, ensuring the safety and service life of the camera 5 and the three-dimensional laser scanning module 7, and the baffles 14 arranged on both sides provide additional physical protection for the camera 5 and the three-dimensional laser scanning module 7 to avoid collisions on uneven or complex road conditions and cause damage to the equipment.
