It refers to the pavement structure composed of cement concrete slab as the surface layer, base layer and cushion layer, also known as rigid pavement; concrete pavement is generally composed of four parts: roadbed, base layer, cushion layer and surface layer. The main material of the surface layer is concrete, which is generally required to be wear-resistant, flat, non-slip, and strong. The cushion layer is set on roads with unsuitable temperature and humidity to change the structure of the pavement. The base layer should have strong deformation resistance, compression resistance, anti-scouring, and solidity.

According to the location to be tested, the lateral position of the treatment box can be adjusted by moving the moving wheels at the bottom of the side frame as a whole. The longitudinal position of the treatment box can be adjusted by controlling the walking mechanism to move forward and backward in the connecting slide bar. The position of the treatment box can be adjusted to complete this step;

[0017] Step Ba, according to the time of putting concrete into the section of the concrete road to be tested, if it is newly put in, drive the second servo motor to rotate the rotating toothed disc clockwise, so that the right toothed plate drives the right lifting material pipe to fall and insert into the concrete road to be tested, and at this time, the micro mud pump is started, and the mud is finally sucked into the second collection box through the right lifting material pipe, the positioning material pipe, and the micro mud pump, so as to realize the sampling of the concrete road surface, and according to the needs, the rotation angle of the rotating toothed disc is controlled, so as to control the insertion depth of the right lifting material pipe;

[0051] A sampling inspection method of a concrete sampling inspection device for a concrete road, the method comprising the following steps;

[0052] Step A: After the carrier frame 1 is assembled, the carrier frame 1 is set up on both sides of the concrete road to be inspected. According to the location to be inspected, the lateral position of the treatment box 3 can be adjusted by moving the moving wheels 17 at the bottom of the side frame 11 to move the whole. The longitudinal position of the treatment box 3 can be adjusted by controlling the walking mechanism 18 to move forward and backward in the connecting slide bar 13. The position of the treatment box 3 can be adjusted to complete this step;

[0053] Step Ba, according to the time of putting concrete into the section of the concrete road to be inspected, if it is newly put in, drive the second servo motor 41 to rotate the rotating toothed disc 42 clockwise, so that the right toothed plate 43 drives the right lifting material pipe 45 to fall and insert into the concrete road to be inspected, and at this time, the micro mud pump 34 is started, and the mud is finally sucked into the second collecting box 27 through the right lifting material pipe 45, the positioning material pipe 44, and the micro mud pump 34, so as to realize the sampling of the concrete road surface, and according to the needs, the rotation angle of the rotating toothed disc 42 is controlled, so as to control the insertion depth of the right lifting material pipe 45;

[0054] Step Bb, according to the time of placing concrete in the section of the concrete road to be inspected, if the surface layer of the concrete is about to solidify, the solid mass can be measured for inspection, and the second servo motor 41 is driven to rotate the rotating gear plate 42 counterclockwise, so that the left gear plate 43 drives the left lifting material pipe 45 to fall and insert into the concrete road to be inspected, and at this time, the first servo motor 26 is started, and the retracting tube 24 is driven to rotate through the transmission belt 25 and the pulley 23, that is, the retracting tube 24 drives the lifting slide bar 22 and the auger 29 to rotate. When the left lifting material pipe 45 is inserted into the concrete road to be inspected, the concrete to be inspected that is about to solidify will pass through the auger 29, and the concrete road to be inspected will be transported upward during the rotation of the auger 29 itself;

[0055] Step C, the auger 29 and the left lifting tube 45 are in a rotational connection relationship, and the up and down movement of the lifting tube 45 can drive the auger 29 to move up and down. When the sample collection is sufficient, the tooth plate 43 drives the left lifting tube 45 to retract, and the lifting slide bar 22 is retracted into the retraction tube 24 at this time, and the top of the auger 29 enters the first collection box 21, and on the auger 29, it will also be semi-air-dried by the fan 32 and the heating plate 33. When entering the first collection box 21, when its left side no longer has friction with any wall surface, the sample of the concrete road to be tested will fall from the left side. At this time, the door on the left side of the first collection box 21 can be opened to take out the sample;

[0056] Step D: while driving the lifting slide bar 22 and the auger 29, the first servo motor 26 will also drive the stirring blade 28 to stir the sample stored inside, which can ensure that the internal sample does not solidify. When it is necessary to discharge the material, the discharge pipe 5 can be opened to discharge the material.

[0057] Furthermore, the length of the connecting slide bar 13 can be selected according to the actual road surface length.

[0058] Furthermore, the walking mechanism 18 has a sliding block inside that cooperates with the first limiting slide groove 14, and the sliding block is connected to the processing box 3. The bottom of the sliding block has wheels and a built-in motor to drive these wheels. Because the walking mechanism 18 belongs to the prior art, it will not be introduced in detail in the present invention.

[0059] In the present invention, firstly, the walking mechanisms 18 on the front and rear sides of the processing box 3 are installed into the corresponding connecting slide bars 13, and after removing the two electric push rods 16, the two connecting slide bars 13 are installed into the second limiting slide grooves 15 on the top frame 12, and then the electric push rods 16 are reinstalled, and the carrier frame 1 is erected on both sides of the concrete road to be detected.

[0060] 1) When concrete is newly put in, the second servo motor 41 is driven to rotate the rotating toothed disc 42 clockwise, so that the right toothed plate 43 drives the right lifting material pipe 45 to fall and insert into the concrete road to be tested. At this time, the micro mud pump 34 is started, and the mud is finally sucked into the second collecting box 27 through the right lifting material pipe 45, the positioning material pipe 44, and the micro mud pump 34, so as to realize the sampling of the concrete road surface. The rotating angle of the rotating toothed disc 42 is controlled according to the needs, so as to control the insertion depth of the right lifting material pipe 45.

[0061] 2) The solid mass can be detected by measuring the solid mass, driving the second servo motor 41 to rotate the rotating toothed disc 42 counterclockwise, so that the left toothed disc 43 drives the left lifting material pipe 45 to fall and insert into the concrete road to be detected, and at this time the first servo motor 26 is started, and the retracting tube 24 is driven to rotate through the transmission belt 25 and the pulley 23, that is, the retracting tube 24 drives the lifting slide bar 22 and the auger 29 to rotate. When the left lifting material pipe 45 is inserted into the concrete road to be detected, the concrete to be detected that is about to solidify will pass through the auger 29, and the concrete road to be detected will be transported upward during the rotation of the auger 29 itself;

[0062] After the sample is collected in 1), the first servo motor 26 drives the stirring blade 28 to rotate, so that the concrete is always kept in a state of just being collected. In this state, it can be detected in real time whether the mass ratio of various components in the concrete is correct. When it is necessary to take the material, the discharge pipe 5 can be opened to pour out the sample.

[0063] After the sample is collected in 2), the tooth plate 43 drives the left lifting material tube 45 to retract, and the lifting slide bar 22 will be retracted into the retraction tube 24, and the top of the auger 29 will enter the first collecting box 21, and on the auger 29, it will also be semi-air-dried by the fan 32 and the heating plate 33. When it enters the first collecting box 21, there is no friction between the left side and any wall surface, and the sample of the concrete road to be tested will fall from the left side. At this time, the door on the left side of the first collecting box 21 can be opened to take out the sample.

[0064] The concrete sampling device for the concrete road is provided with a carrier frame 1 to carry a collection component 2, a processing box 3 and a selective feeding mechanism 4, and the collection component 2, the processing box 3 and the selective feeding mechanism 4 can be set up on an unsolidified concrete road surface, and the walking mechanism 18 can drive the collection component 2, the processing box 3 and the selective feeding mechanism 4 to move left and right, and the electric push rod 16 can drive the connecting slide bar 13 to make a slight forward and backward adjustment, so that the collection component 2, the processing box 3 and the selective feeding mechanism 4 can be used for sampling during all time periods of concrete laying. By providing the collection component 2, the processing box 3 and the selective feeding mechanism 4, sampling can be selected according to the laying time of the concrete. When the concrete is just laid, because it is still in a fluid state, the sample is finally sucked into the second collection unit using the structure on the right. The sample is collected in the first collecting box 27. When the concrete is about to solidify, it is in a semi-solid state. The structure on the left is used to collect the sample into the first collecting box 21. Different collection methods are selected according to different time periods to make the operation more efficient. The semi-solid sample can be further dried so that the sample will be in a finished block state when it enters the first collecting box 21, representing the final quality of the entire concrete. The first servo motor 26 and the stirring blade 28 are used to stir the concrete inside the second collecting box 27, so that the concrete will always be kept in a just-collected state. In this state, it can be detected in real time whether the mass ratio of various components in the concrete is correct. After these two sampling tests, the problematic parts can be replenished with materials in time before the concrete is completely solidified, avoiding the tediousness of dismantling and repairing the finished road.

[0065] All controllers and electronic components used in the present invention can be installed in appropriate sizes and models according to actual conditions while ensuring that the functions of the present invention can be achieved.

[0066] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

8. A sampling inspection method for a concrete road according to any one of claims 1 to 7, characterized in that: The method comprises the following steps: Step A: After the carrier frame (1) is assembled, the carrier frame (1) is set up on both sides of the concrete road to be inspected. According to the location to be inspected, the lateral position of the processing box (3) can be adjusted by moving the moving wheels (17) at the bottom of the side frame (11) as a whole. The longitudinal position of the processing box (3) can be adjusted by controlling the walking mechanism (18) to move forward and backward in the connecting slide bar (13). The position of the processing box (3) can be adjusted to complete this step; Step Ba, according to the time when the concrete of the concrete road to be inspected is put in, if the concrete is newly put in, the second servo motor (41) is driven to rotate the rotating toothed disc (42) clockwise, so that the right toothed plate (43) drives the right lifting material pipe (45) to fall and insert into the concrete road to be inspected, at which time the micro mud pump (34) is started, and the mud is finally sucked into the second collection box (27) through the right lifting material pipe (45), the positioning material pipe (44), and the micro mud pump (34), so as to realize the sampling of the concrete road surface, and according to the needs, the rotation angle of the rotating toothed disc (42) is controlled, so as to control the insertion depth of the right lifting material pipe (45); Step Bb, according to the time when the concrete of the concrete road to be inspected is placed, if the concrete is about to solidify on the surface, the solid mass is measured to perform the inspection, and the second servo motor (41) is driven to rotate the rotating toothed disc (42) counterclockwise, so that the left toothed disc (43) drives the left side lifting material pipe (45) to fall and insert into the concrete road to be inspected, and at this time, the first servo motor (26) is started, and the retracting tube (24) is driven to rotate through the transmission belt (25) and the pulley (23), that is, the retracting tube (24) drives the lifting slide bar (22) and the auger (29) to rotate, and when the left side lifting material pipe (45) is inserted into the concrete road to be inspected, the concrete to be inspected that is about to solidify will pass through the auger (29), and will be transported upward in the concrete road to be inspected during the rotation of the auger (29); Step C, the auger (29) and the left lifting material pipe (45) are in a rotational connection relationship, and the up and down movement of the lifting material pipe (45) can drive the auger (29) to move up and down. When the sample is collected sufficiently, the tooth plate (43) drives the left lifting material pipe (45) to retract, and at this time, the lifting slide bar (22) is retracted into the retraction tube (24), and the top of the auger (29) enters the first collection box (21), and on the auger (29), it is semi-dried by the fan (32) and the heating plate (33). When it enters the first collection box (21), when its left side no longer has friction with any wall surface, the sample of the concrete road to be tested will fall from the left side, and at this time, the door on the left side of the first collection box (21) can be opened to take out the sample; Step D: While driving the lifting slide bar (22) and the auger (29), the first servo motor (26) will also drive the stirring blade (28) to stir the sample stored inside, thereby ensuring that the sample inside does not solidify. When it is necessary to discharge the sample, the discharge pipe (5) can be opened to discharge the sample.
