Technical Field

[0001] The utility model relates to the technical field of concrete pavement flatness detection, in particular to a concrete pavement flatness detection device. Background Art

[0002] Concrete pavement refers to the road surface paved with concrete as the main material. Due to its excellent bearing capacity, durability, anti-skid properties and relatively low maintenance costs, concrete pavement is widely used in highways, airport runways, port terminals, industrial sites and other road projects that require high strength and durability.

[0003] Pavement surface smoothness is a key indicator of road quality, directly impacting the smoothness and safety of vehicle travel.

[0004] Traditional detection methods such as level detection or manual use of a roughness ruler to detect concrete pavements are slow and have low detection accuracy. In order to improve the efficiency and accuracy of detection, laser roughness meters are now widely used. The laser roughness meter is mounted on a mobile device (wheeled vehicle or rail vehicle) to scan and detect the pavement. The existing mobile device loaded with the laser roughness meter moves directly on the detection pavement. If the pavement is uneven, it will cause the detection equipment to tilt, and then cause the mounted laser roughness meter to tilt, causing the detection laser of the laser roughness meter to be skewed, affecting the detection accuracy.

[0026] The following will be combined with the accompanying 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention. Example 1

[0027] Please see the attached Figure 1-Figure 5 The utility model discloses a concrete pavement flatness detection device, comprising a laser flatness meter 13, a sliding detection device 1, a detection guide rail 2 and a guide rail leveling assembly 3, wherein:

[0028] The sliding detection device 1 includes a sliding mounting frame 11, the laser flatness meter 13 is fixed to the lower end of the sliding mounting frame 11, and sliding wheels 121 are installed on both sides of the sliding mounting frame 11;

[0029] The detection guide rails 2 are symmetrically arranged on both sides of the sliding mounting frame 11, and the sliding wheels 121 slide along the detection guide rails 2;

[0030] The guide rail leveling assembly 3 includes a support seat 33 and a leveling seat 31 rotatably connected to the upper end of the support seat 33 and capable of being raised and lowered. The leveling seat 31 is slidably connected to the detection guide rail 2 .

[0031] Further, see the attached Figure 2 , Attachment Figure 3 The guide rail leveling assembly 3 also includes a connecting seat 32, a lifting frame 322 is installed at the bottom of the connecting seat 32, a lifting box 331 is installed on the upper end of the support seat 33, a lifting warehouse 332 is provided in the lifting box 331, the lifting frame 322 is movably connected to the lifting warehouse 332, a slidable adjustment ramp 36 is provided in the lifting warehouse 332, and a side of the bottom of the lifting frame 322 close to the adjustment ramp 36 is provided with an inclined surface that cooperates with the adjustment ramp 36, and a wavy groove is provided at the bottom of the support seat 33 to increase friction, so that the support seat 33 remains stable and will not slide when erected.

[0032] A threaded barrel 34 is installed at the side end of the lifting box 331, and a screw 351 is connected to the inner thread of the threaded barrel 34. One side of the screw 351 passes through the lifting box 331 and is fixedly connected to the adjustment ramp 36. The other side of the screw 351 is installed with an adjustment rocker 35.

[0033] Specifically, the lifting compartment 332 is divided into two parts, one part is for the lifting frame 322 to slide up and down, and the other part is used to accommodate the adjustment ramp 36 and the screw 351. It should be noted that, as shown in the attached Figure 3 As shown, the adjusting ramp 36 can move from the bottom between the two parts of the lifting bin 332. The inclined surface on the adjusting ramp 36 has the same angle and size as the inclined surface of the lifting frame 322. When the adjusting ramp 36 moves to the right, the lifting frame 322 loses its restriction and thus descends. When the adjusting ramp 36 moves to the left, the lifting frame 322 is lifted up by the inclined surface.

[0034] More specifically, the movement of the adjustment ramp 36 is controlled by the adjustment rocker 35 , and the adjustment rocker 35 drives the screw 351 to rotate, so that the screw 351 moves left and right, thereby driving the adjustment ramp 36 to move left and right.

[0035] Further, see the attached Figure 2 A fixed shaft 312 is installed at the bottom of the leveling seat 31, a rotating sleeve 321 rotatably connected to the fixed shaft 312 is installed at the upper end of the connecting seat 32, a sliding block 311 is installed at the upper end of the leveling seat 31, and a sliding groove slidably connected to the sliding block 311 is opened at the bottom of the detection guide rail 2.

[0036] Specifically, when the leveling seats 31 at both ends are raised or lowered under the action of the lifting frame 322 and the adjustment ramp 36, the lifting heights on both sides are different due to leveling, so that the connection between the leveling seat 31 and the detection guide rail 2 needs to be rotated and slid for adaptive adjustment.

[0037] Further, see the attached Figure 4 、 Figure 5 , power boxes 12 are symmetrically installed at both ends of the sliding mounting frame 11, and a motor for driving the sliding wheel 121 to slide is installed in the power box 12. Guide rails 14 are symmetrically installed at the bottom of the sliding mounting frame 11. The upper end of the detection guide rail 2 is provided with a guide groove 22 and a wheel groove 21 for sliding the sliding wheel 121. The guide rail 14 is slidably connected and matched with the guide groove 22. The symmetrically arranged detection guide rails 2 are installed on one side close to each other with a correction laser emitter 23 and a laser correction plate 24. The correction laser emitter 23 and the laser correction plate 24 on one side of the detection guide rail 2 are respectively aligned and matched with the laser correction plate 24 and the correction laser emitter 23 on the other side of the detection guide rail 2.

[0038] Specifically, after the sliding detection device 1 is mounted on the detection guide rail 2, the guide rail 14 slides in the guide groove, and under the restriction of the guide groove, the sliding mounting frame 11 maintains a straight sliding motion, thereby preventing the sliding path of the sliding mounting frame 11 from deviating or shaking, and further improving the detection accuracy of the laser flatness meter 13;

[0039] When setting up the detection guide rail 2, the laser emitted by the calibration laser emitter 23 on the detection guide rail 2 is compared with the position of the laser on the laser calibration plate 24 on the detection guide rail 2 on the other side, so as to quickly align the detection guide rails 2 on both sides, thereby improving the accuracy and efficiency of the installation of the detection guide rail 2. Example 2

[0040] Based on the above embodiment 1, in order to increase the flatness detection length, the detection guide rail 2 can be spliced ​​and extended. Figure 6 , Attachment Figure 7A splicing plate 26 is installed at the front end of the detection guide rail 2, and a splicing groove 25 is provided at the rear end of the detection guide rail 2, which is movably connected and fits with the splicing plate 26. The splicing plate 26 and the splicing groove 25 are both provided with corresponding assembly holes 261.

[0041] In this embodiment, the splicing plate 26 on the spliced ​​detection guide rail 2 is aligned with the splicing groove 25 of the detection guide rail 2 to be spliced, so that the splicing plate 26 is horizontally inserted into the splicing groove 25, and then the bolts are screwed into the splicing holes in the splicing plate 26 and the splicing groove 25 to extend the detection guide rail 2, thereby increasing the area scanned and detected by the laser flatness meter 13 during a single detection.

[0042] The working principle and use process of the utility model are as follows: two detection guide rails 2 are set up on the concrete road surface to be inspected at a certain distance. The specific spacing between the two detection guide rails 2 is the spacing between the sliding wheels 121 on the sliding mounting frame 11. Then, the calibration laser emitter 23 is started. The laser emitted by the calibration laser emitter 23 on one side of the detection guide rail 2 is illuminated on the position of the laser calibration plate 24 on the other side of the detection guide rail 2, so that the detection guide rails 2 on both sides are quickly aligned.

[0043] Put the level ruler on the detection guide rail 2 and place it in the middle position of the detection guide rail 2, and level the detection guide rail 2 by observing the level ruler. During this process, the leveling is performed by shaking the adjustment rockers 35 on the guide rail leveling assemblies 3 on both sides of the detection guide rail 2. The adjustment rockers 35 rotate in the threaded cylinder 34 through the screw 351 to move the screw 351 left and right, thereby driving the adjustment inclined platform 36 to move left and right. The adjustment inclined platform 36 moves left and right to lift the lifting frame 322 and drive the connecting seat 32 and the leveling seat 31 to lift. When the connecting seat 32 and the leveling seat 31 are lifted and lowered, the connecting seat 32 and the leveling seat 31 rotate adaptively through the fixed shaft 312 and the rotating sleeve 321, and the leveling seat 31 slides adaptively on the bottom of the detection guide rail 2.

[0044] Place the sliding mounting frame 11 on the detection guide rail 2, so that the sliding wheels 121 on both sides of the sliding mounting frame 11 enter the wheel grooves 21 on different guide rails. Since the two detection guide rails 2 are leveled, the sliding mounting frame 11 drives the laser roughness meter 13 to slide horizontally on the detection guide rail 2 through the sliding wheels 121. The detection laser emitted by the laser roughness meter 13 will not be skewed. The laser roughness meter 13 performs flatness detection on the concrete pavement as the sliding mounting frame 11 slides.
