Description

Technical Field

[0001] This utility model relates to the field of road and bridge construction testing technology, specifically a handheld rapid detection device for road rut depth. Background Technology

[0002] Rutting refers to longitudinal depressions or grooves on the road surface caused by repeated loads from vehicles traveling on it. Rutting is one of the common defects of asphalt pavements, usually occurring in sections with high traffic volume and heavy vehicles. It manifests as longitudinal depressions along the direction of travel and may be accompanied by the flow or compaction of pavement materials, seriously affecting the road's performance and safety.

[0003] Therefore, rut depth is a major indicator for measuring the severity of ruts and also an important indicator of road surface smoothness.

[0004] Road surface smoothness refers to the degree of deviation between the road surface and an ideal plane, and is one of the important indicators for measuring road quality. It directly affects the comfort and safety of vehicle driving, as well as the service life of the road.

[0005] Currently, the common methods for detecting road rutting are: the ruler method, which uses a ruler or level to measure the maximum gap between the road surface and the ruler, suitable for small-scale inspections; the three-meter ruler method, which uses a three-meter ruler to measure the road surface smoothness, suitable for rapid inspections at construction sites; the laser smoothness meter, which uses laser technology to measure changes in road surface elevation, with high accuracy, suitable for large-scale inspections; and the inertial profiler, which uses an inertial measurement system mounted on a vehicle to continuously measure the longitudinal profile of the road surface, suitable for long-distance inspections.

[0006] However, conventional detection methods still have the following shortcomings:

[0007] 1. Small-scale detection methods have a limited detection range and low accuracy;

[0008] 2. Intelligent detection methods, while increasing the detection range and improving detection accuracy, require large size and weight. Utility Model Content

[0009] To address the technical problems existing in the background art, this utility model provides a handheld rapid detection device for road rut depth, which has a large detection range, high accuracy, and is easy to hold and carry.

[0015] Furthermore, the two sides of the horizontal arm box are respectively provided with sliding holes that are slidably connected to the lifting rod in the vertical direction.

[0016] Furthermore, the lower end of the lifting rod is provided with an insertion hole, and an upper limit seat protruding downwards is provided on the side wall of the lifting rod. A set of screw holes communicating with the insertion hole is provided on the side wall of the lifting rod, and a bolt is screwed into the set of screw holes.

[0017] Furthermore, the screw hole group is provided in multiple circular arrangements along the axis of the lifting rod.

[0019] Furthermore, the radial cross-sections of the upper limit seat and the lower limit seat are set as a sector with a central angle of 45°, so that the axial rotation angle of the upper lifting rod and the lower lifting rod is limited to 180°.

[0020] Furthermore, an upper magnet is provided on the side wall where the upper limit seat's sector radius is located.

[0039] Based on the specific structure of the handheld road rut depth rapid detection device in the above embodiments, its working process will be further explained below:

[0045] B. Rotation:

[0046] Rotate the horizontal arm box (10) around the lifting upper rod (20) and lifting lower rod (21) assembly on one side of the horizontal arm box (10). Due to the upper limit seat (201) and lower limit seat (211) set on the lifting upper rod (20) and lifting lower rod (21) assembly on this side, the horizontal arm box (10) rotates 180° around the center of the lifting upper rod (20) and lifting lower rod (21) assembly on this side, maintaining the height position of the lifting upper rod (20) and lifting lower rod (21) assembly on this side.

[0047] The lifting switch (14) at the handle (13) on the other side of the horizontal arm box (10) controls the lifting of the stroke cylinder (30) on that side, and the levelness is observed by the level gauge (11);

[0048] After ensuring the horizontal arm box (10) is level by using the level gauge (11), the distance measuring probe (15) is activated by triggering the distance measuring probe in the button group (12) to detect and record the flatness of the road surface between the two sides of the upper lifting pole (20) and lower lifting pole (21) assembly.

[0049] C. Continuous detection:

[0050] Using the upper limit seat (201) and lower limit seat (211) respectively set on the upper lifting rod (20) and lower lifting rod (21) assembly on both sides of the boom box (10), repeat step B above to make the boom box (10) travel along the road surface, detect the road surface flatness and record it.
