Specific embodiments

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] An embodiment of a highway pavement construction quality detection device of the present invention, as Figures 1 to 7As shown in the figure, a device for detecting the construction quality of a highway pavement includes a mounting frame 100, a leveling mechanism, and a detection mechanism; the leveling mechanism includes a reciprocating assembly and four leveling plates 210. The leveling plates 210 are in the shape of rectangular plates, are vertically arranged, and the transverse edges are parallel to the road surface. When the leveling plates 210 are close to the road surface and the leveling plates 210 slide along the ground, they can level the gravel pile. The four leveling plates 210 are circumferentially evenly distributed along the reference axis, and the transverse edges at the lower ends of the four leveling plates 210 are on the same horizontal plane. One vertical edge of a leveling plate 210 is slidably arranged on the side wall of an adjacent leveling plate 210 so that when the leveling plate 210 slides, the transverse edge at the lower end of the leveling plate 210 levels the gravel pile. Two adjacent leveling plates 210 are perpendicular to each other, and the area enclosed by the four leveling plates 210 is the first area 230, and the vertical projection of the first area 230 is square. The reciprocating assembly is arranged on the mounting frame 100 and is used to drive the leveling plate 210 to reciprocate and slide on the side wall of the adjacent leveling plate 210, so that the first area 230 first becomes larger and then smaller, so as to achieve the best leveling effect on the gravel pile. Specifically, a slide rail 213 is provided on the side surface of the leveling plate 210, and the slide rail 213 is perpendicular to the vertical edge of the leveling plate 210. Specifically, the slide rail 213 is located on the perpendicular bisector of the vertical edge of the leveling plate 210. A clamping groove 214 is provided on one vertical edge of the leveling plate 210, and the clamping groove is in a notch state. The leveling plate 210 can be slidably connected to the slide rail 213 of an adjacent leveling plate 210 through the clamping groove 214.

[0039] The detection mechanism includes a sampling component and a detection component 330. The sampling component is arranged on the mounting frame 100 and is activated after the gravel is leveled, and is used to sequentially collect gravel of different sizes in the first area 230; the detection component 330 weighs the gravel collected by the sampling component, so as to obtain the mass of the gravel in the first area 230, and then calculates the road surface texture depth of the road surface in the first area 230. The road surface texture depth is calculated according to the mass of the gravel in the first area 230, and the mass of the gravel in the first area 230 and the road surface texture depth are positively correlated. Specifically, according to the actual mass of the gravel in the first area 230 measured multiple times, the detection component 330 calculates the mass of the gravel on the road surface corresponding to the lower side of the screed 210 in the first area 230. Subtracting the actual mass of the sampled gravel in the first area 230 from the mass of the gravel on the road surface corresponding to the lower side of the screed 210 in the first area 230, so as to obtain the mass in the first area 230 that does not include the mass of the gravel on the road surface corresponding to the lower side of the screed 210 in the first area 230. The detection component 330 calculates the road surface texture depth of the road surface corresponding to the first area 230 according to the mass of the gravel in the first area 230 that does not include the mass of the gravel on the road surface corresponding to the lower side of the screed 210 in the first area 230, so as to achieve the effect of reducing the error of the road surface texture depth. The detection component 330 includes a display screen 331; the display screen 331 is arranged on the mounting frame 100 and is used to display the road surface texture depth.

[0040] In this embodiment, as Figures 1 to 7As shown in the figure, the reciprocating assembly includes a first motor 221, a sliding plate 234, a guiding block 222, and a plurality of guiding rods 235. The sliding plate 234 is horizontally arranged on the mounting frame 100 and is located above the screed plate 210. One of the four screed plates 210 is fixedly connected to the sliding plate 234. Specifically, the screed plate 210 fixedly connected to the sliding plate 234 is the second plate 212, and the other three screed plates 210 are the first plates 211, so that the second plate 212 is in a relatively stationary state with respect to the mounting frame 100. The guiding block 222 is conical, and a guiding groove 223 is provided on the guiding block 222. The guiding groove 223 spirally extends upward along the circumferential surface of the guiding block 222, so that the guiding groove 223 gradually moves away from the axis of the guiding block 222 from top to bottom. One end of each guiding rod 235 is fixedly connected to the screed plate 210, and the other end is slidably inserted into the guiding groove 223. When the guiding block 222 rotates in the first rotation direction, the area of the first region 230 increases, and when the guiding block 222 rotates in the second rotation direction, the area of the first region 230 decreases; the first rotation direction and the second rotation direction are opposite to each other. Since the second plate 212 is fixedly connected to the sliding plate 234, when the guiding block 222 rotates, the guiding block 222 moves up and down relative to the screed plate 210. Particularly, the heights of the other ends of the guiding rods 235 in the guiding groove 223 are different, so that the lengths of the guiding rods 235 are different. Specifically, in the initial state, the other end of the guiding rod 235 is located at the upper end of the guiding groove 223. At this time, the distances between the other ends of the guiding rods 235 and the axis of the guiding block 222 are the closest, and the area of the first region 230 is in the smallest state. When the guiding block 222 rotates in the first rotation direction, it drives the other end of the guiding rod 235 to slide downward along the guiding groove 223, so that the upper end of the guiding rod 235 gradually moves away from the axis of the guiding block 222, thereby driving the corresponding screed plate 210 to slide, and then increasing the area of the first region 230. On the contrary, when the guiding block 222 rotates in the second rotation direction, the area of the first region 230 decreases. The first motor 221 is slidably arranged on the sliding plate 234 and is used to drive the guiding block 222 to rotate. A sliding groove is provided on the sliding plate 234; the first motor 221 is slidably mounted in the sliding groove. The guiding block 222 is slidably connected to the output shaft of the first motor 221, so as to ensure that when the guiding block 222 rotates, it can move up and down relative to the screed plate 210. Since the second plate 212 and the mounting frame 100 are in a relatively stationary state, when the first region 230 expands or contracts, the first plate 211 adjacent to the second plate 212 slides along the second plate 212, so that the first motor 221 slides on the sliding plate 234 by the movement of the first plate 211 relative to the mounting frame 100. The reciprocating assembly further includes a connecting plate 236; one end of the connecting plate 236 is fixedly connected to the sliding plate 234, and the other end is fixedly connected to a screed plate 210. Specifically, the other end of the connecting plate 236 is fixedly connected to the second plate 212.

[0041] In this embodiment, as Figures 1 to 7 shown, the sampling assembly includes a suction pipe 310, a connecting pipe 320 and a suction machine. The suction pipe 310 is vertically arranged below the guiding block 222 and is located in the first region 230. Specifically, the suction pipe 310 is coaxially arranged with the guiding block 222. The suction pipe 310 is rotatably connected to the guiding block 222 so that the suction pipe 310 moves up and down with the guiding block 222. The suction pipe 310 sucks the gravel in the first region 230. Particularly, the suction pipe 310 is coaxial with the inscribed circle of the first region 230. The suction machine is communicated with the suction pipe 310 through the connecting pipe 320, and the suction machine is used to collect the gravel in the first region 230 through the suction pipe 310. Particularly, the connecting pipe 320 can be a rigid pipe. One end of the connecting pipe 320 is connected to the suction pipe 310, so as to support the suction pipe 310. Further, when the area of the first region increases, the power of the suction machine is appropriately increased, so that the suction force at the edge of the first region 230 with different areas by the suction pipe 310 remains unchanged, thereby reducing the quality error caused by sampling; or, the suction pipe 310 is held by hand to suck the gravel in the first region 230 with different areas. When holding the suction pipe 310 by hand, it is necessary to ensure that the distance between the suction pipe 310 and the leveling plate 210 is kept consistent in the first region 230 with different areas, and at the same time, the distance between the suction pipe 310 and the road surface is kept consistent.

[0042] In this embodiment, as Figure 1 shown, the leveling mechanism further includes a second motor 260 and a lifting rod. The lifting rod is a threaded rod, which is vertically inserted into the sliding plate 234. The lifting rod is threadedly connected to the sliding plate 234, so as to drive the sliding plate 234 to move up and down when the lifting rod rotates, and further be able to adjust the distance between the lower lateral edge of the leveling plate 210 and the road surface. The second motor 260 is arranged on the mounting frame 100 and is connected to the lifting rod to drive the lifting rod to rotate.

[0043] An embodiment of the usage method of a highway pavement construction quality detection device, as Figures 1 to 8 shown, includes the following steps:

[0044] S100: Place the gravel in the first region 230. The region surrounded by the four leveling plates 210 is the first region 230; the four leveling plates 210 also divide the second region 240 and the third region 250; in order to have a better leveling effect, gravel piles can be placed in both the second region 240 and the third region 250 as shown in Figure 6 ;

[0045] S200: The reciprocating assembly increases the area of the first region 230, and the leveling plate 210 slides relative to the road surface to level the gravel pile;

[0046] S300: The sampling component collects gravel in the first area 230 and measures the actual mass of the gravel M1; the theoretical mass of the gravel in the first area 230 (i.e., the mass of the gravel in the first area without the influence of the error) is set to m (m is the theoretical mass of gravel per unit area), and the value of m can determine the depth of the road surface structure; the mass of the gravel hidden under each caressing plate 210 is set to A (the mass of the gravel on the road surface corresponding to the lower side of the caressing plate in the first area 230); and M1=m+4*A is derived;

[0047] S400: the side length of the first area 230 is increased by 2 times, the sampling assembly collects the gravel in the first area 230 at this moment, and measures the actual mass of the gravel M2, where M2 is the sum of the mass collected for the first time and the mass collected for the second time; the mass of the gravel in the first area 230 at this moment is set to 22m; and M2=m2+2*4A is derived;

[0048] S500: Based on the two formulas containing the theoretical mass m of gravel and the error amount A obtained in S300 and S400, the two equations are combined to obtain A1; then the side length of the first area 230 is enlarged by 3 times and the gravel in the first area is collected, and the actual mass M3 of the gravel is measured. At this moment, the theoretical mass of the gravel in the first area 230 is set to 32m, and it is derived that M3=32m+4*3*A.

[0049] S600: Based on the two formulas containing the theoretical mass m of gravel and the error A obtained from S400 and 5400, the two equations are combined to obtain A2, and the average of A1 and A2 is calculated. The average value can be regarded as the value of A.

[0050] S700: Expand the side length of the first area 230 by K times, collect the gravel in the first area 230, and measure the actual mass MK of the gravel; at this moment, the theoretical mass of the gravel in the first area 230 is set to K2m; and derive MK=K2m+4*K*A, and substitute the value of A obtained in step S600 to obtain the theoretical gravel mass m, which is positively correlated with the road surface structural depth value D. Therefore, the calculated road surface structural depth can eliminate or reduce the influence of the gravel mass hidden under each stroking plate 210, thereby reducing the error value of the road surface structural depth.

[0051] In this embodiment, step S500 and step S600 are for obtaining a relatively accurate value of A as far as possible. In actual situations, if the error requirement is low, the second half of step S500 and step S600 can be omitted, and the A1 value obtained according to S300 and S400 can be regarded as the value of A. The theoretical gravel mass m can also be obtained.

[0052] In some other embodiments, in order to further reduce the error, the following steps are further included after step S500:

[0053] In step S510, expand the side length of the first area to n times, collect the gravel within the first area, and measure the actual mass Mn of the gravel at this multiple. At this moment, the theoretical gravel mass within the first area is n2m, and it is deduced that Mn = n2m + 4 * n * A. In this step, n is any natural number greater than 3 and less than K.

[0054] Step S600 further includes:

[0055] Repeat step S510, where the values of n are 4, 5... n respectively. Obtain A3, A4... An - 1 according to the derivation formulas under adjacent two values, and regard the average value of A3, A4... An - 1 as the value of A. Thus, by taking multiple values and calculating the average value, the error of A is further reduced, thereby reducing the error of m, and finally being able to reduce the error of the road surface texture depth.

[0056] In some other embodiments, the other - side gravel can be repeated multiple times, and each time the first area 230 expands from the smallest area outwards. At this time, the samples collected by the sampling component each time are all the gravel within the first area 230.

[0057] During operation, as Figures 1 to 8 shown, turn on the second motor 260. The second motor 260 drives the sliding plate 234 to move downward through the lifting rod, thereby driving the screed 210 to move downward. When the screed 210 moves downward to contact the road surface, turn off the second motor 260.

[0058] Place gravel piles in the first area 230, the second area 240, and the third area 250. Start the first motor 221, and the first motor 221 drives the guide block 222 to rotate reciprocally. The guide block 222 drives the screed 210 to slide relative to the ground through a plurality of guide rods 235. Since the second plate 212 and the sliding plate 234 are fixedly connected, when the first plate 211 slides relative to the second plate 212, it drives the first motor 221 to slide along the sliding plate 234.

[0059] After the screed 210 levels the gravel, the first motor 221 drives the guide block 222 to rotate again, so that the first area 230 expands to the first preset area. Start the suction machine, and the suction machine collects the gravel within the first preset area through the suction pipe 310. At this time, M1 = m + 4 * A (Formula 1) can be obtained;

[0060] Start the first motor 221 again, so that it drives the guide block 222 to rotate, and then expand the first area 230 to the second preset area. Start the suction machine, and the suction machine collects the gravel within the second preset area through the suction pipe 310. At this time, M2 = 22m + 2 * 4 * A (Formula 2) can be obtained;

[0061] The values of A1 are obtained by simultaneously solving two formulas (Formula 1 and Formula 2).

[0062] Start the first motor 221 again to drive the guide block 222 to rotate, thereby expanding the first area 230 to the third preset area. Start the suction machine, and the suction machine collects the gravel within the third preset area through the suction pipe 310. At this time, M3 = 32m + 3 * 4 * A (Formula 3) can be obtained;

[0063] The values of A2 are obtained by simultaneously solving two formulas (Formula 2 and Formula 3).

[0064] Repeat the above steps to successively obtain the values of A1 to An-1, and calculate the average value A. A is the average mass of the gravel hidden under each screed 210. Substitute A into Mn = m + 4 * n * A to obtain the value of m. The detection component 330 calculates the specific value of the road surface texture depth based on the theoretical mass m of the gravel.

[0065] In some other embodiments, since the intake angle of the suction pipe in the sampling component is constant, it is difficult to ensure the suction effect when the area of the first area changes. Therefore, the suction effect can be ensured by appropriately lifting the suction pipe and increasing the suction force of the suction pipe, or the suction pipe can search the first area along a fixed path within the first area to ensure the suction effect.

[0066] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
