Description

Technical Field

[0001] This utility model relates to the field of highway engineering technology, and in particular to a highway pavement construction quality testing device. Background Technology

[0002] Road surface inspection is a crucial step in ensuring road quality and traffic safety. Inspectors need to carefully observe the road surface for damage such as cracks, potholes, loose surfaces, and peeling. Cracks are a common problem, including transverse cracks, longitudinal cracks, and network cracks. For example, transverse cracks are usually caused by road surface shrinkage due to temperature changes, while longitudinal cracks may be caused by uneven settlement of the subgrade or cracks reflected from the pavement base layer. For crack inspection, information such as location, length, width, and depth must be recorded. Potholes are localized depressions in the road surface, which may be caused by material aging, vehicle overloading, or water damage. During inspection, the size and depth of potholes must be recorded.

[0003] The utility model application with application number 202123369753.4 discloses a road surface damage detection device. Through the cooperation of the transmission mechanism and the recording mechanism, the marking pen can record the road surface damage on the surface of the paper. When the paper is used up, the disc is removed, the disc is separated from the rod, and the roller is taken out from the second through hole for easy observation by the staff to analyze the road surface damage. When the paper needs to be replaced, the top cover is opened, the new paper is placed on the surface of the conveyor roller, the conveyor is placed on the surface of the limit rod, and then one end of the paper is wrapped around the surface of the roller.

[0004] However, the detection range of the aforementioned road surface damage detection device is affected by the width of the first roller, making it impossible to fully detect the road surface and prone to missed detections. In the aforementioned road surface damage detection device, the marking pen and the toothed plate move up and down synchronously to draw lines on the paper to record the damage, which requires the staff to compare the paper length to find the damage location, resulting in low efficiency and high paper consumption. Therefore, this utility model proposes a highway pavement construction quality detection device to solve the problems existing in the prior art. Utility Model Content

This device uses laser rangefinders arranged downwards to illuminate the road surface and performs real-time distance measurement as the mobile platform moves. It can judge the road surface damage based on changes in the measured distance, effectively preventing missed detections. A second electric telescopic rod extends and drives a second lifting frame to descend, bringing the marking stamp into contact with the road surface for easy marking of road damage. At the same time, the marking type is switched as the rotating wheel rotates, facilitating quick location of damage points.

[0020] according to Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, this embodiment provides a highway pavement construction quality inspection device, including a mobile platform 1, a damage detection mechanism, a clearing mechanism, and a damage marking mechanism. The damage detection mechanism includes a through slot 2, a fixed frame 3, a first extension frame 4, a laser rangefinder 5, auxiliary wheels 6, and a light shield 7. The mobile platform 1 has a through slot 2 in the middle, and the fixed frame 3 is fixedly mounted in the middle of the mobile platform 1. The first extension frame 4 is symmetrically fixed at the front and rear of the fixed frame 3.

A light shield 7 is fixedly installed on the upper part of the fixed frame 3. Multiple sets of laser rangefinders 5 are provided. The light shield 7 surrounds and shields the laser rangefinders 5. When the detection is carried out, the laser rangefinders 5 are activated and illuminate the ground downwards. The laser rangefinders 5 use the changes in the measured distance to judge the degree of road damage. At the same time, the light shield 7 covers the outside of the laser rangefinders 5 to prevent external light from affecting the distance measurement accuracy, so as to achieve full detection of the road surface and prevent missed detection. A clearing mechanism is provided on one side of the mobile platform 1, and a damage marking mechanism is fixedly installed on the other side of the mobile platform 1.

[0021] The obstacle removal mechanism includes a second extension frame 8, a first electric telescopic rod 9, a first lifting frame 10, and an obstacle removal shovel 11. The second extension frame 8 is fixedly installed on one side of the moving platform 1. The first electric telescopic rod 9 is fixedly installed on the second extension frame 8. The first lifting frame 10 is fixedly installed at the telescopic end of the first electric telescopic rod 9. The obstacle removal shovel 11 is fixedly installed below the first lifting frame 10. The obstacle removal shovel 11 descends to fit with the ground. The obstacle removal shovel 11 has a V-shaped cross-section when viewed from above. When inspection is performed, the first electric telescopic rod 9 extends and drives the first lifting frame 10 and the obstacle removal shovel 11 to descend and fit with the ground, shoveling away excess debris and garbage on the ground to prevent affecting the inspection accuracy.

[0022] The damage marking mechanism includes a third extension frame 12, a second electric telescopic rod 13, a second lifting frame 14, a rotating chamber 15, a rotating wheel 16, and a marking stamp 17. The third extension frame 12 is fixedly mounted on the other side of the moving platform 1. The second electric telescopic rod 13 is fixedly mounted on the third extension frame 12. The second lifting frame 14 is fixedly mounted at the telescopic end of the second electric telescopic rod 13. The rotating chamber 15 is fixedly mounted at the bottom of the second lifting frame 14.

Rollers 18 are fixed at the four corners of the bottom. A handle 19 is fixed on the other side of the mobile platform 1. A controller 20 is fixed on the handle 19. The controller 20 is electrically connected to the motor. When damage occurs, the second electric telescopic rod 13 extends and drives the second lifting frame 14 to descend, which in turn drives the rotating wheel 16 and the marking stamp 17 to descend and fit against the ground, marking the ground to help staff quickly find the damaged location. When faced with different types of road damage, the controller 20 controls the motor to drive the rotating wheel 16 to rotate and switch between different marking stamps 17, making it easy to distinguish different types of road damage.

[0023] When this highway pavement construction quality inspection device is in operation, pushing the handle drives the moving platform to move stably under the action of rollers. At the same time, the first electric telescopic rod extends, driving the first lifting frame and the clearing shovel to descend and clear away the debris in front. The laser rangefinder is activated to measure the change in distance between the road surface and the laser rangefinder as the device moves to determine road damage. When damage is found, the second electric telescopic rod extends, driving the second lifting frame to descend and imprint a marking stamp on the road surface, making it easy for staff to quickly find the damage point based on the marking. When it is necessary to change the marking according to the type of road damage, the motor drives the rotating wheel to rotate and switch to different marking stamps facing downwards.
