DETAILED DESCRIPTION

[0018] 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.

[0019] Example 1: Please refer to Figure 1-Figure 4, a highway pavement maintenance quality inspection device shown in the figure comprises a mobile vehicle 1, on which a detection port 2 is arranged, and also comprises a track 3 fixed on the mobile vehicle 1, on which a mobile seat 4 is slidably sleeved, and a support frame 5 is fixed at one end of the mobile seat 4, and a detection unit 6 for highway pavement repair area detection is installed on the support frame 5; and a positioning member 7 installed on the support frame 5, the positioning member 7 is connected to the track 3 to position the mobile seat 4; and an adjusting member 8 installed on the support frame 5, and the positioning member 7 is adjusted by the adjusting member 8; In this solution, personnel move the support frame 5 to drive the detection unit 6 to move in the repair area on the road surface, so as to detect the degree of unevenness of the repair area and determine whether it meets the standards. Compared with naked eye observation, the detection is more accurate.

[0020] For further information, see Figure 3-Figure 5 The positioning member 7 includes a main rod 9 that slides through the support frame 5, a connecting plate 10 is fixed on the top of the main rod 9, and positioning rods 11 are fixed at both ends of the connecting plate 10. A positioning hole 12 is opened on the track 3, and the bottom of the positioning rod 11 slides through the movable seat 4 and is plugged into the positioning hole 12. A docking sleeve 13 that is slidably sleeved with the positioning rod 11 is fixed on the side wall of the support frame 5, a docking plate 14 is fixed on the outer side of the bottom of the positioning rod 11, and an extrusion spring 15 that resists the docking sleeve 13 and the docking plate 14 is sleeved on the outer side of the positioning rod 11; Also, see Figure 2-Figure 5 The adjusting member 8 includes an adjusting plate 16 rotatably mounted on the bottom of the supporting frame 5, and an arc rod 17 is fixed to the bottom of the adjusting plate 16. The arc rod 17 is slidably plugged with the main rod 9. The arc rod 17 is driven to move by the adjusting plate 16, so that the main rod 9 is lifted or lowered.

[0021] In this solution, the principle of the positioning member 7 being lifted by the adjusting member 8 is as follows: When the support frame 5 needs to be driven to move along the track 3 again, the personnel first pinch the adjustment plate 16 and move the adjustment plate 16 toward the main rod 9, so that the arc rod 17 moves accordingly, thereby driving the main rod 9 to move up. Under the action of the connecting plate 10, the two positioning rods 11 move up synchronously and fall off the positioning opening 12 on the track 3, so that the outer side is out of the positioning effect, and the personnel can then move the support frame 5; After completing the inspection, the personnel moves the support frame 5 to the initial position, then loosens the adjustment plate 16, and under the action of the extrusion spring 15, drives the docking plate 14 and the positioning rod 11 to move downward and plug into the positioning port 12 again to achieve the positioning of the support frame 5.

[0022] It should also be noted that in order to facilitate personnel to pinch the adjustment plate 16, a fitting sleeve 18 that fits the main rod 9 is fixed on the support frame 5, so that personnel can pinch and adjust the adjustment plate 16 with one hand. At the same time, in order to make the operation more comfortable for personnel, the shape of the adjustment plate 16 is designed to be arc-shaped, and the outer side of the adjustment plate 16 is covered with a rubber sleeve.

[0023] For further information, see Figure 1 and Figure 5-Figure 7 The detection part 6 includes a connecting frame 19 fixed to the supporting frame 5, the other end of the connecting frame 19 is fixed to the moving seat 4 through a supporting plate, a detection rod 20 is slidably inserted on the connecting frame 19, a detection wheel 21 is rotatably installed at the bottom of the detection rod 20, a detection member 22 is installed at the top of the detection rod 20, and an elastic member 23 is installed on the outer side of the detection rod 20, through which the detection wheel 21 can move in accordance with the repair area of ​​the road surface; The elastic member 23 includes a connecting sleeve 24 fixed to the bottom of the connecting frame 19, a connecting plate 25 is fixed to the bottom of the detection rod 20, and a buffer spring 26 is sleeved on the outer side of the detection rod 20 to abut against the bottom of the connecting sleeve 24 and the connecting plate 25; At the same time, the detection component 22 includes a mercury tilt switch 27 and an end plate 28 fixed to the top of the detection rod 20. Telescopic rods 29 are installed at both ends of the mercury tilt switch 27. One of the telescopic rods 29 is hinged to the outer side of the end plate 28. A threaded cylinder 30 is rotatably installed on the top of the connecting frame 19. An adjusting rod 31 is inserted into the inner thread of the threaded cylinder 30, and the other telescopic rod 29 is hinged to the adjusting rod 31.

[0024] In this solution, the principle of using the detection unit 6 to detect the road surface repair area is as follows: First, the personnel moves the mobile vehicle 1 to the repair area, and then pinches the adjustment plate 16 to move the main rod 9 upward and the positioning rod 11 out of the positioning port 12, and then pulls the support frame 5 to drive the corresponding movement of the detection part 6, so that the detection wheel 21 moves along the repair area. When moving to the concave-convex area, the detection rod 20 is driven to rise and fall accordingly, thereby driving the corresponding rise and fall of the end plate 28, so that the mercury tilt switch 27 changes from a horizontal state to an inclined state. When the mercury tilt switch 27 tilts to a certain degree, a light will appear. At this time, it is judged that the concave-convex degree of the repair area is too large and does not meet the quality inspection requirements. On the contrary, after the repair area is moved, there is no light, which means that the horizontal degree of the area meets the standard.

[0025] In this solution, when testing the repaired part of the inclined road section: When on an inclined road section, the operator first rotates the threaded cylinder 30 to make the adjustment rod 31 rise and fall accordingly, so that the mercury tilt switch 27 remains in a horizontal state. Then, when the mobile support frame 5 drives the detection unit 6 to detect the repaired road section, the mercury tilt switch 27 can be used to determine whether the degree of concavity of the repaired area meets the standard.

[0026] It should be noted that, in order to facilitate personnel to rotate the threaded barrel 30 , an adjusting wheel 32 is provided on the outer side of the threaded barrel 30 .

[0027] Example 2: Please refer to Figure 6 and Figure 7 This embodiment further explains the first embodiment, and the difference lies in that a partial structure is disclosed to ensure that the detection wheel 21 does not contact the ground when not detecting.

[0028] Specifically, a mounting block 33 is fixed to the bottom of the connecting frame 19, a slide rod 34 is slidably inserted in the mounting block 33, an adjustment seat 35 that fits with the bottom of the connecting frame 19 is fixed to one end of the slide rod 34, an adjustment column 37 is fixed to the detection rod 20, an inclined plate 36 that fits with the adjustment column 37 is fixed to the adjustment seat 35, a traction rope 38 is fixed between the slide rod 34 and the adjustment seat 35, and a push spring 39 is sleeved on the outer side of the slide rod 34 for pushing the adjustment seat 35 toward the detection rod 20.

[0029] In this solution, when the personnel pinch the adjustment plate 16 and rotate it, the traction rope 38 will be driven to pull the sliding rod 34, so that the adjustment seat 35 and the inclined plate 36 will move accordingly. When the inclined plate 36 is withdrawn, the adjustment column 37 will move down along the inclined plate 36 accordingly, so that the detection rod 20 will move down, allowing the detection wheel 21 to start to contact the road surface. When not detecting, the adjustment seat 35 can be driven to move toward the detection rod 20 through the push spring 39, so that the inclined plate 36 lifts the adjustment column 37, allowing the detection wheel 21 to move up, thereby avoiding the detection wheel 21 always contacting the road surface when the mobile vehicle 1 is pushed, and causing it to be worn and damaged by long-term contact.
