[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] Example 1: Please refer to Figure 1 - Figure 5 , a road surface base measurement device for highway construction shown in the figure includes a plurality of track frames 1, the plurality of track frames 1 are butted end to end into two groups, a connecting seat 2 is fixed to the outer side of the track frame 1, a latch hole is provided on the connecting seat 2, and the connecting seat 2 is distributed on both sides of the highway, and also includes two moving seats 3, the two moving seats 3 are distributed on both sides of the highway, and are respectively butted with the track frames 1 on both sides of the highway, a traveling member 4 is installed in the moving seat 3, and the moving seat 3 is driven to move in the track frame 1 by the traveling member 4; and two detection plates 5 distributed on both sides of the highway, a connecting plate 6 is fixed on the detection plate 5, a connecting member 7 is inserted on the connecting plate 6, a connecting column 8 plugged with the connecting member 7 is fixed on the moving seat 3, a rolling member 9 in contact with the highway surface is installed at the bottom of the detection plate 5, and a laser detector 10 is installed on the two detection plates 5;

[0027] In this solution, the designed traveling member 4 provides power to drive the moving seat 3 to move in the track frame 1. The connecting column 8 and the connecting member 7 cooperate with each other to drive the detection plate 5 and the laser detector 10 to move synchronously accordingly. As the moving seat 3 moves, the flatness detection of a section of the road surface is realized. Compared with the traditional fixed-point detection method, the detection result is more accurate.

[0028] It should also be noted that the laser detector 10 is composed of a laser generator and a laser receiver. The laser generator and the laser receiver are respectively installed on two detection plates 5. When the two detection plates 5 move synchronously, the laser receiver can always receive the laser emitted by the laser generator, and through the position of the received laser, it can calculate the flatness of the ground on both sides of the highway, thereby realizing the detection of the flatness of continuous road sections.

[0029] For further information, see Figure 4 and Figure 5 as well as Figure 7 The travel member 4 includes a roller 11 rotatably mounted on the bottom of the moving seat 3, the roller 11 is in contact with the inner wall of the track frame 1, a travel motor 12 is fixed on the moving seat 3, a driving gear 13 is fixed to the output end of the travel motor 12, and a transmission gear 14 meshing with the driving gear 13 is fixed to the outer side of the roller 11;

[0030] It should be noted that: the driving gear 13 is driven to rotate by the travel motor 12, so that the transmission gear 14 and the roller 11 are rotated, and the movement in the track frame 1 is realized, so as to facilitate the detection of the flatness of the road surface;

[0031] It should also be noted that in order to improve the stability of the moving seat 3 in the track frame 1, two recesses 15 are provided in the track frame 1, and the two sides of the moving seat 3 slide in contact with the two recesses 15. At the same time, the width of the moving seat 3 is equal to the distance between the inner walls of the two recesses 15, and the moving seat 3 slides in contact with the inner walls of the recess 15.

[0032] For further information, see Figure 4 and Figure 7 The connecting member 7 includes a sliding sleeve 16 that is slidably sleeved with the connecting column 8, a connecting shaft 17 is fixed to the outer side of the sliding sleeve 16, and a rotating sleeve 18 that is rotatably sleeved on the outer end of the connecting shaft 17 and plugged into the connecting plate 6;

[0033] The connecting plate 6 on the detection plate 5 is plugged into the connecting shaft 17 through the rotating sleeve 18. As the moving seat 3 moves, the connecting column 8 will be driven to move accordingly. During the movement, it is inevitable that the connecting column 8 will be slightly skewed due to the unevenness of the road surface. The connecting shaft 17 and the rotating sleeve 18 are rotated and sleeved, and the sliding sleeve 16 and the connecting column 8 are fitted together, so that the moving seat 3 and the detection plate 5 can be tilted and raised when they move relative to each other.

[0034] For further information, see Figure 5 The rolling element 9 includes a double-axis motor 21 fixed on the detection plate 5, a driving shaft 22 is fixed at both ends of the double-axis motor 21, a connecting plate 23 is fixed at both ends of the driving shaft 22, and a hemisphere 24 is fixed on both sides of the connecting plate 23 through a rotating shaft.

[0035] In this solution, the two hemispheres 24 are rotatably connected to the connecting plate 23, so that the normal movement of the detection plate 5 can be achieved when the detection plate 5 travels along the road surface.

[0036] For further information, see Figure 3 A docking port 29 is provided at one end of the track frame 1, and a docking plate 30 adapted to the docking port 29 is fixed at the other end. Both the docking plate 30 and the docking port 29 are provided with docking holes 31, and are docked with the two docking holes 31 by screws;

[0037] The principle of docking multiple track frames 1 is as follows: personnel first dock two track frames 1 with each other, so that one of the docking plates 30 docks with the docking port 29, and uses screws to achieve docking between two or more track frames 1, which can control the road surface detection range. At the same time, the detachable design makes it easier to carry and store.

[0038] In this solution, when inspecting the flatness of the road surface, personnel first install two sets of track frames 1 on the ground on both sides of the road, then clean the surface of the road to be inspected, clean the gravel piles and sand, and then install the moving seat 3. Under the power provided by the traveling part 4, the moving seat 3 is moved synchronously. During the movement, the laser detector 10 detects in real time to detect the horizontality of this section of the road. Compared with the traditional fixed-point detection, the detection range is large and the results are more representative.

[0039] Example 2: Please refer to Figure 7 This embodiment further explains the first embodiment, and the difference lies in that the insertion method of the rotating sleeve 18 is improved.

[0040] Specifically, a screw rod 19 is threadedly inserted on the connecting plate 6, a rotating cap 20 is fixed on the top of the screw rod 19, and the bottom is against the outer side of the rotating sleeve 18. At the same time, in order to improve the stability of the screw rod 19 against the rotating sleeve 18, a flat opening is opened on the outer side of the rotating sleeve 18, and a rubber pad is laid on the flat opening;

[0041] The screw rod 19 abuts against the rotating sleeve 18 , so that the rotating sleeve 18 can be tightly locked, which is convenient for locking and releasing the detection plate 5 .

[0042] Example 3: Please refer to Figure 1 , Figure 5 and Figure 6 This embodiment further illustrates other embodiments, and the difference lies in that components such as a rotating rod 25 are added to the detection plate 5 to assist in the detection of the flatness of the road surface.

[0043] Specifically, both ends of the detection plate 5 are rotatably connected with a rotating rod 25, the bottom of the rotating rod 25 and the outer side of the driving shaft 22 are fixed with mutually matching bevel gears 26, the top of the rotating rod 25 is fixed with an I-shaped wheel 27, and a connecting belt 28 is fixed between the two I-shaped wheels 27 located on both sides of the highway.

[0044] It should be noted that after the moving seat 3 travels to a certain position, the personnel loosens the rotating cap 20 so that the screw rod 19 does not interfere with the rotating sleeve 18, and then rotates the dual-axis motor 21 to make the two drive shafts 22 rotate synchronously, so that the two hemispheres 24 rotate, and at the same time, the two bevel gears 26 cooperate with each other to rotate the rotating rod 25, and the connecting belt 28 is rotated and wrapped around the outside of the industrial wheel 27. When the two detection plates 5 are moved close to each other, the personnel observe the two connecting belts 28 on the two detection plates 5 to observe whether the tightness of the two connecting belts 28 is consistent, and whether the two detection plates 5 can be accurately close to each other after moving towards each other, so as to judge whether the road surface is level.

[0045] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
