[0001] The present invention relates to the technical field of civil engineering, and particularly relates to a highway engineering pavement quality detection device and a detection method thereof. Background Art

[0002] The highway engineering pavement refers to one or more structural layers paved with various road construction materials on top of the highway subgrade. Its main function is to provide a flat and solid driving surface for vehicles, and directly bear the action of vehicle loads and natural factors (such as temperature and humidity changes).

[0003] In the prior art, during the detection of a specimen, if there are loose but not yet completely detached fragments on the surface of the specimen, when the pressure load is applied to the critical point, these fragments may suddenly fall off and cause an instantaneous tremor of the testing device, resulting in abnormal collected values and deviating from the true results. Summary of the Invention

[0004] The present invention discloses a highway engineering pavement quality detection device and a detection method thereof, aiming to solve the technical problem in the background art that when there are loose but not yet completely detached fragments on the surface of the specimen, during the detection process, the falling off of the fragments will cause an instantaneous tremor of the testing device, resulting in abnormal detection results.

[0005] A highway engineering pavement quality detection device proposed by the present invention includes a main cabinet body. An installation plate frame is fixedly connected to the inner wall of the main cabinet body. A pretreatment module and a cleaning module are arranged on the installation plate frame.

A placement tray is arranged on the top of the installation plate frame, and a test specimen body is arranged on the top of the placement tray.

[0006] In a preferred solution, a rotating shaft is movably connected to the bottom of the installation plate frame. A driven gear is fixedly connected to the outside of the rotating shaft. Tooth bars are fixedly connected to the bottoms of the two sliding blocks. The two tooth bars are both engaged with the driven gear. A driving motor is fixedly connected to the bottom of the installation plate frame. The output end of the driving motor is fixedly connected with a driving gear. The driving gear is engaged with the driven gear.

[0007] In a preferred solution, the tops of the two sliding tables are fixedly connected to mounting ring frames, two circular holes are provided on the two mounting ring frames, rotating rods are movably connected in the multiple circular holes, rotating rollers are fixedly connected to the outsides of the multiple rotating rods, and the tops of the multiple rotating rods are fixedly connected to transmission wheels, the outer walls of the two transmission wheels on the same side are slidably connected to the same transmission belt, universal motors are fixedly connected to the two mounting ring frames, and the output ends of the two universal motors are fixedly connected to the corresponding rotating rods.

[0008] In a preferred embodiment, movable holes are provided on the two mounting ring frames, cleaning rollers are movably connected in the two movable holes, and servo motors are fixedly connected to the tops of the two mounting ring frames, and the output ends of the two servo motors are fixedly connected to the tops of the corresponding cleaning rollers.

[0009] By setting up a pretreatment module, the driving motor rotates the active gear, driving the gear rods and sliding blocks on both sides to slide toward each other, so that the sliding table and the mounting ring frame move toward the center until the rotating roller is in close contact with the sample body. The universal motor drives the rotating roller to rotate synchronously through the transmission wheel and the transmission belt, driving the sample body to rotate. The servo motor rotates the cleaning roller to clean up the impurities attached to the sample body and the fragments that are about to fall off. It can actively remove loose debris and critical falling particles on the surface of the sample, avoid instantaneous vibration of the test device caused by the collapse of fragments, and effectively ensure the stability and accuracy of the test data.

[0010] In a preferred solution, the tops of the two mounting frames are fixedly connected to negative pressure bins, one ends of the two negative pressure bins are fixedly connected to connecting pipes, and one side of the two mounting frames is fixedly connected to collecting bins, one end of the two connecting pipes away from the negative pressure bins are fixedly connected to the corresponding collecting bins, two hydraulic rods are fixedly connected in the two sliding grooves, and the driving ends of the multiple hydraulic rods are fixedly connected to the corresponding sliding seats.

[0011] In a preferred solution, mounting holes are provided on the two negative pressure bins, negative pressure pumps are fixedly connected in the two mounting holes, and filter cartridges are fixedly connected to the inner walls of one side of the two negative pressure bins.

[0013] By setting up a cleaning module, the hydraulic rod pushes the sliding seat and the mounting frame to move towards the center. The negative pressure pump keeps the interior of the negative pressure chamber in a negative pressure state. The fallen impurities and debris are sucked into the collection bin and enter the negative pressure chamber through the connecting pipe. The stepping motor rotates the connecting rod to drive the cleaning cylinder to clean the exterior of the filter cylinder, preventing the filter cylinder from being blocked and affecting the cleaning efficiency. It can collect and clean the debris generated inside the device, ensuring the cleanliness inside the device and the stability of operation.

[0014] In a preferred solution, a plurality of limiting rods are fixedly connected to the top of the mounting plate frame. The outer walls of the plurality of limiting rods are slidably connected to the same protective frame, and two fixing holes are provided on the protective frame. Hydraulic pumps are fixedly connected to both fixing holes, and pressing plates are fixedly connected to the driving ends of the two hydraulic pumps.

The output ends of the two winding motors are fixedly connected to winding wheels. Winding ropes are wound around the outsides of the two winding wheels, and the ends of the two winding ropes far from the winding wheels are fixedly connected to the top of the protective frame.

[0016] By setting up the winding motor, winding wheel, winding rope and protective frame, the winding motor rotates the winding wheel to loosen the winding rope, causing the protective frame to fall by gravity. The protective frame slides down the outer wall of the limiting rod to the mounting plate frame. The hydraulic pump pushes the pressing plate to conduct a strength test on the test sample body. When detecting, the falling of the protective frame can prevent the broken pieces from bursting from damaging the internal components of the device.

[0017] A method for detecting the pavement quality of highway engineering, using a device for detecting the pavement quality of highway engineering as described above, includes the following steps:

[0018] Step 1: Open the movable door, place the test sample body and the placement tray at the designated positions. Start the driving motor through the control panel to make the two mounting ring frames move towards the center until the rotating roller is in close contact with the test sample body. Start the universal motor to drive the rotating roller to rotate synchronously, driving the test sample body to rotate. At the same time, the servo motor rotates the cleaning roller to clean the exterior of the test sample body.

[0019] Step 2: After the pretreatment module resets, the hydraulic rod pushes the mounting frame to move towards the center. The negative pressure pump keeps the interior of the negative pressure chamber in a negative pressure state. The fallen impurities and debris are sucked into the collection bin and enter the negative pressure chamber through the connecting pipe. At the same time, the stepping motor drives the cleaning cylinder to clean the exterior of the filter cylinder.

[0020] Step 3: After the cleaning module resets, the winding motor rotates the winding wheel to loosen the winding rope, causing the protective frame to slide down the outer wall of the limiting rod to the mounting plate frame. Start the hydraulic pump to push the pressing plate to conduct a strength test on the test sample body.

[0021] As can be seen from the above, a road engineering pavement quality detection device provided by the present invention can actively remove loose debris and critically detachable particles on the surface of the specimen through the pretreatment module, promote the premature peeling of unstable fragments without damaging the test block body, and recycle the slag through the negative pressure adsorption system in the cleaning module, avoiding the instantaneous tremor of the testing device caused by the collapse of the fragments, and effectively ensuring the stability and accuracy of the detection data.

Start the general motor 513, and under the action of the transmission wheel 511 and the transmission belt 512, drive the rotating roller 510 to rotate synchronously, driving the test sample body 8 located in the center to rotate.

The protective frame 10 slides down the outer wall of the limiting rod 9 onto the mounting plate rack 4. Start the hydraulic pump 14 to push the pressing plate 15 to conduct a strength test on the test sample body 8.
