DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Example 1: Please refer to Figure 1-Figure 5, a road pavement thickness detection device shown in the figure includes a plurality of horizontal plates 1 that can be spliced, a track groove 2 is provided on the horizontal plate 1, and a moving seat 3 slidably inserted in the track groove 2, a moving assembly 4 is installed on the moving seat 3, and the moving seat 3 is driven to move in the track groove 2 by the moving assembly 4; and a reeling unit 5 installed at one end of the moving seat 3, and the roll paper is placed by the reeling unit 5, a clamping assembly 6 for clamping one end of the paper is installed on the outermost horizontal plate 1, and a detection unit 7 that fits the road surface is installed on the moving seat 3, and the road surface data is drawn on the paper by the detection unit 7;

[0028] In this solution, the moving seat 3 is driven to move along the track groove 2 through the designed moving component 4, thereby driving the corresponding movement of the unwinding unit 5 and the detection unit 7. The movement of the detection unit 7 will fit the road surface and directly draw the road surface information on the paper. Therefore, personnel can understand the road surface information more clearly and intuitively according to the drawn lines on the paper, thereby improving the detection efficiency and making it easier to find the sunken area of ​​the road. When drilling the sunken area, it can more effectively determine whether the road section in the area is qualified, thereby reducing the number of drilling holes and improving the integrity of the road.

[0029] For further information, see Figure 4-Figure 6 The unwinding unit 5 includes a docking base 8 fixed on the movable seat 3, an outer cylinder 9 is inserted on the docking base 8, an insertion rod 10 is fixed on the docking base 8, a paper roll 11 is inserted on the insertion rod 10, an opening 12 for pulling out one end of the paper roll 11 is opened on the outer cylinder 9, and an abutting member 13 is installed on the top of the outer cylinder 9;

[0030] The abutting member 13 includes an abutting plate 14, which is fitted with the top of the paper roll 11, and is slidably plugged with the insertion rod 10. An extrusion spring 15 fixed to the top of the outer tube 9 is fixed inside the abutting plate 14.

[0031] Also, see Figure 7 and Figure 8 The clamping assembly 6 includes a clamping column 16, a through slot 17 for paper to pass through is opened in the clamping column 16, a rotating slot 18 is opened in the through slot 17, a rotating shaft 19 is rotatably installed in the rotating slot 18, an abutting column 20 that moves in the rotating slot 18 is fixed to the outside of the rotating shaft 19, and a rotating cap 21 that is easy for personnel to adjust is fixed to the top of the rotating shaft 19. Through the rotation of the abutting column 20, the paper in the through slot 17 is clamped and released, and a plug column 22 is fixed to the bottom of the clamping column 16, and a plug hole compatible with the plug column 22 is opened on the horizontal plate 1.

[0032] The principle of paper extraction during highway inspection: first, during inspection, the personnel first open the outer tube 9, insert the paper roll 11 onto the insertion rod 10, then extract one end of the paper roll 11, then cover the outer tube 9, pull out one end of the paper roll 11, and insert it into the through slot 17. Then, the personnel rotate the rotating cap 21 to make the rotating shaft 19 and the abutting column 20 rotate accordingly, squeezing the paper, thereby achieving the clamping and positioning of the paper. Then, the unwinding unit 5 realizes the step-by-step paper unwinding operation by moving the movable seat 3.

[0033] It should also be noted that in order to prevent the clamping column 16 from rotating easily after installation, the shape of the plug column 22 is set to be a diamond rod.

[0034] For further information, see Figure 4-Figure 6 The moving assembly 4 includes a driving motor 36 fixed on the moving seat 3, a driving gear 23 is fixed to the output end of the driving motor 36, and a toothed plate 24 adapted to the driving gear 23 is fixed to the horizontal plate 1;

[0035] The driving motor 36 is used to drive the driving gear 23 to rotate, so that the driving gear 23 moves stably along the tooth plate 24 , and then drives the moving seat 3 to move along the track groove 2 .

[0036] For further information, see Figure 4 and Figure 5 The detection unit 7 includes a detection plate 26 fixed on the movable seat 3, a detection rod 27 is slidably inserted in the detection plate 26, a rolling ball 28 that fits the ground is fixed to the bottom of the detection rod 27, a push spring 29 that drives the detection rod 27 to move downward is sleeved on the outer side of the bottom end of the detection rod 27, a movable sleeve 30 is slidably sleeved on the outer side of the top end of the detection rod 27, an adjusting cap 31 that is threadedly sleeved with the detection rod 27 is rotatably installed on the top of the movable sleeve 30, an insertion plate 32 is fixed on the outer side of the movable sleeve 30, a recording pen 33 that fits the paper is inserted in the insertion plate 32, and the detection rod 27 is a rod-shaped structure with at least one plane on the outer side.

[0037] The principle of the detection unit 7 to intuitively display the road surface conditions is as follows: first, assemble the cross plate 1 so that the multiple cross plates 1 are in a horizontal state, and a level meter can be used for auxiliary installation, then insert the movable seat 3, and then assemble the paper roll 11, and then clamp one end of the paper roll, and then install the recording pen 33, and fit one end of the recording pen 33 to the paper, and finally, the movable seat 3 is driven by the moving component 4 to move along the track groove 2. During the movement, the ball 28 at the bottom of the detection rod 27 fits with the ground, and is adjusted up and down accordingly according to the unevenness of the ground, so that the recording pen 33 moves up and down accordingly when drawing lines along the paper. After the movement is completed, the personnel can judge the difference between the convex and concave areas of the road surface according to the difference between the two ends of the line segment on the paper, and can also judge the surface conditions of the highway according to the direction of the route, so that when the thickness is detected, the area where the thickness does not meet the standard can be found intuitively, and then the hole digging detection is carried out, making the detection more representative;

[0038] It should also be noted that in this solution, multiple horizontal plates 1 can span the road surface and can also be along the direction of the road route to detect the road surface conditions for a distance. Before each detection, the debris on the road is cleaned up first, and the outside of the rolling ball 28 is cleaned, so that the subsequent detection rod 27 can be moved up and down more accurately.

[0039] In this solution, in order to make the movement of the detection rod 27 more stable, a stabilizing sleeve 34 which is sleeved with the detection rod 27 is fixed at the bottom of the detection plate 26, and the push spring 29 abuts against the outer end of the stabilizing sleeve 34;

[0040] At the same time, in order to facilitate the installation and removal of the recording pen 33, a tightening rod 35 is threadedly inserted on the installation plate 32.

[0041] Example 2: Please refer to Figure 5 This embodiment further explains the first embodiment, and the difference lies in that the structure of the movable seat 3 is optimized, and the ball 25 designed at the bottom can reduce the friction.

[0042] Specifically, the cross-sectional shape of the track groove 2 is an inverted T-shape, and a ball 25 is installed at the bottom of the moving seat 3. The ball 25 fits the bottom of the track groove 2. The ball 25 is used to change the sliding friction into rolling friction, thereby greatly reducing the friction force generated by the moving seat 3 during the movement, making the movement smoother.
