Embodiment 1

[0021] In this implementation, the folding box 1 has a length of 600 millimeters, the main box body 3 has a length of 2100 millimeters, and the foldable rutting detection instrument is installed at the front of the car body 10 . In this embodiment, a total of 17 distance sensors 11 are used to equidistantly install the folding boxes 1, 12 and the main box body 3 at intervals of 200 mm.

[0022] combine figure 1 , the present invention is in the working state, the two folding boxes on the left and right sides of the main box body rotate around the axis of rotation, and are on a straight line with the main box body, and the tension plate 7 is now located between the folding boxes 1, 12 and the main box body 3 , The tension rod 8 is in contact with the tension plate 7 .

[0023] combine image 3 , the present invention is in the working state, the folding box rotates around the shaft, when the folding box is in correct contact with the main box body 3 and the unfolded positioni...

Embodiment 2

[0026] In this implementation, the folding box 1 has a length of 600 millimeters, the main box body 3 has a length of 2100 millimeters, and the foldable rutting detection instrument is installed at the front of the car body 10 . In this embodiment, a total of 33 distance sensors 11 are installed on the folding box 1 and the main box body 3 at intervals of 100 mm.

[0027] combine figure 2 In the non-working state of the present invention, the two folding boxes 1 on the left and right sides of the main box body 3 rotate through the rotating shaft 2 and overlap with the main box body 3 .

[0028] combine Figure 4 , the present invention is in the non-working state, loosen the tension rod 8 and the tension plate 7, make the folding box 1 rotate around the rotating shaft 2, until the folding box 1 contacts the side of the main box body 3, adjust the tension rod 8 and fix the tension The plate 5 contacts and tightens the tension rod 8, and the fixed plate 4 acts as an upper and...

Abstract

The invention provides a foldable track detecting apparatus comprising a pair of folding boxes, a rotating shaft, a main box body, a fixing plate, a fixed tensioning plate, an unfolded positioning plate, a tensioning plate, a tensioning rod, a heightening plate, a vehicle body and a distance sensor. The pair of folding boxes are respectively arranged at the left and the right sides of the main box body and are connected with the main box body through the rotating shaft. The rotating shaft, the fixing plate, the fixed tensioning plate, the unfolded positioning plate, the tensioning plate and the heightening plate are respectively arranged on the main box body. The vehicle body is connected with the main box body through the heightening plate. The distance sensor is arranged on the folding box and the main box body. The invention overcomes a defect that an ordinary detection apparatus is wider than an ordinary vehicle; as the foldable track detecting apparatus is small and does not influence the safety of the vehicle running, the safety of the detection process is greatly improved; and meanwhile, the foldable track detecting apparatus has simple structure, does not increase the cost and has wide application scope.

Description

(1) Technical field [0001] The invention relates to a rut detection technology, in particular to a foldable rut detection instrument. (2) Technical background [0002] With the rapid development of my country's transportation, accurate and timely detection of road damage has become an increasingly prominent problem. As one of the main disease forms of asphalt pavement in our country, rutting seriously affects driving safety and transportation economy. Rutting detection and evaluation is one of the important basis for determining the maintenance plan, and it is also an indispensable technical content for long-term monitoring of the road surface. Most of the current rutting detection in our country adopts manual methods, using a ruler as a detection tool, and using manual direct measurement. The means are backward and extremely unsuitable for the operating environment of modern road traffic. At the same time, due to the backward detection methods and low detection efficiency...
