DETAILED DESCRIPTION

[0025] 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.

[0026] Embodiment 1:

[0027] like Figure 1-9 As shown, the embodiment of the present invention provides a flatness measuring device for road construction, including a mobile vehicle plate 1 and an inspection mechanism. The top of the mobile vehicle plate 1 is fixedly connected with a fixing frame 3. The setting of the fixing frame 3 is mainly used for the installation of a counterweight 13. A moving groove 4 and a swinging groove 5 are arranged on the left side wall of the fixing frame 3, and the swinging groove 5 is located below the moving groove 4. The setting of the moving groove 4 and the swinging groove 5 is convenient for the counterweight 13 to rotate. A through hole 6 is arranged on the left side wall of the mobile vehicle plate 1, and the through hole 6 is arranged corresponding to the swinging groove 5. Sliding holes 7 are arranged on the front and rear inner walls of the mobile groove 4. The setting of the sliding holes 7 is convenient for the electric cylinder 9 to control the cross plate 8 to drive the counterweight 13 to move up and down. When the cross plate 8 moves to the bottom of the sliding hole 7, it is in a working state. When not in use, the electric cylinder 9 moves the cross plate 8 to the top of the sliding hole 7. At this time, the counterweight 13 contacts the top of the swinging groove 5 to avoid the swinging of the counterweight 13. The interior of the sliding hole 7 is slidably connected with the cross plate 8. The bottom of 8 is fixedly connected with a rotating seat 10, and a rotating shaft 11 is rotatably connected on the inner wall of the rotating seat 10. A connecting column 12 is fixedly connected to the circumferential surface of the rotating shaft 11, and a counterweight 13 is fixedly connected to the bottom end of the connecting column 12. The setting of the counterweight 13 is mainly used to control the inspection mechanism to maintain the level. The counterweight 13 always keeps the horizontal plane vertical under the action of gravity. It should be noted that a friction block 15 is provided in the present application to perform friction limiting on the counterweight 13 to prevent the counterweight 13 from swinging due to small shaking. The speed of the moving vehicle plate 1 cannot be too fast and needs to be moved forward slowly. Two electric cylinders 9 are fixedly connected to the top of the moving vehicle plate 1, and are symmetrically arranged on the front and rear sides of the fixed frame 3. The movable end of the electric cylinder 9 is fixedly connected to the cross plate 8, and the left end of the rotating shaft 11 is fixedly connected to the connecting shaft 39. The left end of the connecting shaft 39 is fixedly connected to the inspection mechanism. The setting of the rotating shaft 11 and the connecting shaft 39 facilitates the counterweight 13 to drive the inspection mechanism to rotate together and maintain synchronization.

[0028] An adjusting groove 14 is provided on the right inner wall of the movable groove 4, and a friction block 15 is slidably connected inside the adjusting groove 14. An adjusting rod 16 is rotatably connected to the right side wall of the friction block 15, and the adjusting rod 16 is threadedly connected to the fixed frame 3. The friction block 15 is controlled to contact or squeeze the counterweight 13 through the adjusting rod 16.

[0029] The inspection mechanism includes a mounting plate 19, a fixed bracket 20, a fixed cylinder 21, a sliding cavity 22, a slide plate 23, a vertical rod 24, a spring 25, a measuring wheel 26, a measuring plate 27, an indicator mark 28, a through groove 29, a scale mark 30, a movable cavity 31, a connecting plate 32, a vertical plate 33, a color card 34 and an observation port 35. The setting of the sliding cavity 22 is convenient for the slide plate 23 to slide up and down inside the fixed cylinder 21. When detecting the flatness of the road surface, when the slide plate 23 drives the vertical rod 24 to move up, it means that the road surface is convex, and when the slide plate 23 drives the vertical rod 24 to move down, it means that the road surface is concave. During the inspection, when the cross plate 8 moves to the bottom of the sliding hole 7, the slide plate 23 is located in the middle position (initial position) of the sliding cavity 22. The setting of the measuring wheel 26 is convenient for rolling on the road surface. The setting of the through groove 29 is convenient for the measuring plate 27 to slide up and down inside the mounting plate 19, thereby driving the indicator mark 28 to move up and down on the scale mark 30, which is convenient for the staff to understand The data of road surface convexity or concavity, the setting of the movable cavity 31, the connecting plate 32, the vertical plate 33, the color card 34 and the observation port 35 are convenient for the inspectors to quickly understand the position of the road surface unevenness. Therefore, the detection position is relatively correct, and a relatively obvious reference object needs to be set to remind the inspectors. The present application reminds the staff by setting the color card 34. The principle is that a plurality of lines of different colors are set on the color card 34 and arranged from top to bottom. The width of each line is the same as the width of the observation port 35. At the initial position, the positions of the plurality of color cards 34 are the same, and the colors seen from the observation port 35 are the same. In the process of detecting the flatness of the road surface, when the position of the measuring plate 27 changes, the color card 34 will also change accordingly. Therefore, the color seen by the staff from the observation port 35 changes, thereby judging the unevenness of the road surface. After that, the staff judges the data of convexity or concavity by the position of the corresponding indicator mark 28 on the scale mark 30 below;

[0031] A card hole 38 is provided inside the cross plate 8, and a positioning rod 17 is threadedly connected to the right side wall of the fixing frame 3, and the positioning rod 17 is correspondingly arranged to the card hole 38. When the cross plate 8 moves to the top of the sliding hole 7, the positioning rod 17 is screwed into the inside of the card hole 38, so as to fix the cross plate 8 to prevent the electric cylinder 9 from suddenly losing power. A push handle 18 is also fixedly connected to the top of the mobile vehicle plate 1, and the push handle 18 is located on the right side of the fixing frame 3. The push handle 18 is used to control the movement of the mobile vehicle plate 1. A controller 37 is provided on the right side wall of the fixing frame 3.

Moving wheels 2 are installed at the four corners of the bottom of the mobile vehicle plate 1, and a power supply 36 is provided at the edge of the bottom right side wall of the mobile vehicle plate 1. The power supply 36 mainly provides power for the electric cylinder 9, and the power supply 36 is a rechargeable type.

[0032] Working principle: When in use, the staff first unscrews the positioning rod 17 from the inside of the clamping hole 38, and then the electric cylinder 9 controls the cross plate 8 to move to the bottom of the sliding hole 7. At this time, the inspection mechanism always remains horizontal under the action of the counterweight block 13. Then the staff controls the mobile vehicle plate 1 to move slowly through the push handle 18, and quickly understands whether the road surface is flat from the observation port 35 during the movement.
