In the invention, when the detector sinks into a road surface base layer, the left and right ends of a dislocation rod are simultaneously disengaged from contact on a circuit contact at a circuit rod position, and at the same time, an infrared lamp in a power supply device is no longer lit due to disconnection of a closed circuit. Since it is known that the detector is not level with the road surface, the invention adjusts the position of the support mechanism or manually fills an uneven base layer, so that two support mechanisms in each group around are in synchronous activity and the detector is adjusted to a state parallel to the road surface, ensuring that the gap between the detector and the road surface will not expand due to tilting, and then ensuring that the detector is parallel to the road surface for vertical compaction detection, ensuring that radioactive elements are vertically detected on the road surface without the gap expanding, causing the radioactive elements to easily diffuse to the surroundings.

Description

Technical Field

[0001] The invention relates to the technical field of road surface detection devices, and in particular to an intelligent road surface compaction detection device for highway engineering. Background Art

[0002] In pavement construction projects, rollers are used to compact the roadbed to facilitate the laying of concrete for pouring. It is necessary to test the compaction of the roadbed to ensure that the roadbed can bear the pouring of concrete without sinking. It is necessary to ensure that the compaction is above a certain value. The compaction detection methods include destructive detection and non-destructive detection methods. Among them, intelligent detection is a non-destructive detection method and will not damage the road surface. Intelligent detection is also called the radioactive element method, which also uses radioactive elements to determine the density and moisture content of the roadbed or pavement material by scattering or direct transmission method, and calculate the compaction degree.

[0003] However, during the compaction process, the road base layer is uneven due to the presence of gravel, and the detection device will also be placed along with the unevenness of the road base layer. The placed detection device needs to be supported to ensure that there is a gap with the road surface and there will be no collision. When the support height is adjusted by adjusting the lifting rod through a thread, the support lifting rod of the road base layer is easy to sink into the uneven road base layer, which in turn causes the support to be unstable and sink into the uneven base layer, so that the detection device tilts along with the sinking position, causing the detection device to be not parallel to the road surface and tilt. After the detection device is not parallel to the road surface, the gap between the detection device and the road base layer will expand, resulting in the problem of radioactive elements easily expanding outward from the gap during detection. Summary of the invention

[0004] The present invention provides an intelligent road surface compaction detection device for highway engineering, which overcomes the shortcomings described in the background technology.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] An intelligent road surface compaction detection device for highway engineering includes a support mechanism, a detector, a display screen, and a controller. The controller and the display screen are integrally installed in the middle of the detector. The support mechanism is provided with eight, and every two of the support mechanisms form a group, which are arranged in four groups in a square on the outside of the detector. The four groups of support mechanisms support the detector and make the detector parallel to the road surface. When the detector is pressed downward, the support mechanism is pressed against the road surface and slides with the outside of the detector.

[0007] The support mechanism is provided with a slide groove, a staggered structure, a friction plate, a power supply, and a support block. The friction plates are respectively arranged in the two slide grooves on the sides of the support block. The power supply is arranged inside the side of the support block, and the power supply is electrically connected to the staggered structure. The staggered structure connects the inside of every two support blocks, and the power supply circuit in each support block is connected in series to the staggered structure. When the two staggered structures are tilted to the horizontal line, the staggered structure tilts to disconnect the closed loop formed by the power supply.

[0008] A better technical solution: the power supply is provided with a battery and an infrared lamp, and the infrared lamp lights up when the closed circuit of the power supply is energized, wherein when the offset structure in two connected power supplies is tilted, the offset structure disconnects the circuit of the power supplies, and since the two support blocks of each group are one side outside the detector, the power supplies in each group of support blocks on the outside can only remain energized when each side of the detector remains horizontal with each other.

[0009] A better technical solution: a fixing bar is provided at the slide groove position and connected to the outside of the detector, and the fixing bar slides in the slide groove. When the detector is pressed downward, the fixing bar is driven to be squeezed with the friction plate, and after the pressure on the detector stops, the fixing bar is fixed against the side of the friction plate.

[0010] A preferred technical solution: A ring-shaped bottom block is provided at the bottom of the support block, and the bottom block is made of rubber. When the road surface is curved, the bottom block is in arc contact with the road surface.

[0011] A better technical solution: the dislocation structure is provided with a fixed rod, a circuit rod, a dislocation rod, a circuit box, and a square groove. The circuit box is arranged in the square groove and connected to the power supply circuit. The dislocation rod is hinged and rotatably arranged on the upper end of the fixed rod. When the two support blocks of each group are horizontal, the dislocation rod maintains a horizontal state, and the left and right ends of the dislocation rod are in contact with the circuit rods in each of the two support blocks. When the support block is tilted, the dislocation rod is driven to rotate around the fixed rod and the contact between the left and right ends of the dislocation rod and the circuit rod is loosened.

[0012] A preferred technical solution: the circuit pole is provided with a circuit contact, a copper wire, and a plastic plate, the two copper wires are arranged in the plastic plate and are respectively connected to the positive and negative poles of the circuit box, and the two copper wires are connected to the two circuit contacts.

[0013] A preferred technical solution: arc-shaped copper end points are provided at the left and right ends of the dislocation rod. When the dislocation rod remains stationary, the copper end points contact two circuit contacts at the same time and connect the two copper wires in a closed loop.

[0014] A better technical solution: the friction plate is provided with a connecting plate and a baffle plate, and the baffle plates are equidistantly arranged on the side of the connecting plate, and the connecting plate is arranged at the slide groove position on the side of the support block, and a vertical limit groove is provided in the slide groove. When the detector is pressed downward, the fixed bar is driven to move in the slide groove in the support block, and the fixed bar is moved vertically in the limit grooves on both sides of the slide groove. At the same time, the fixed bar is pressed against the baffle plate, and the side of the baffle plate is in a continuous triangular state. When the fixed bar stops moving, it stays in the triangular groove limit formed by the triangular state of the baffle plate.

[0015] A better technical solution: the fixed bar is provided with rollers, skateboards, and connecting blocks. The skateboards are arranged on both sides of the connecting block, and balls are provided on the left and right sides of the skateboard. The skateboard slides vertically on the inner side of the support block at the limit groove position. There are four rollers, which are symmetrically distributed in the upper and lower positions of the side of the connecting block, and the outer layer of the roller is made of rubber material, which is deformed by sliding and squeezing with the baffle plate. When the fixed bar stops moving, the rollers are supported on the triangular state of the side of the baffle plate.

[0016] A preferred technical solution: The detector is provided with four grooves around it into which fingers can be inserted. When the detector is pressed downward, the back of the hand is bent from both sides to press against the plastic plate, and the fingers are inserted into the grooves on both sides of the detector, so that the back of the hand supports the fixed support mechanism, and the detector and the support mechanism can slide vertically through the up and down movement of the fingers.

[0017] Compared with the prior art, this technical solution has the following advantages:

[0018] In the present invention, the detector is pressed to detect whether the uneven road surface base is parallel to it. When the detector sinks into the road surface base, the left and right ends of the offset rod are simultaneously disengaged from the circuit contacts at the circuit rod position. At the same time, the infrared lamp in the power supply is no longer lit due to the disconnection of the closed circuit. Since it is known that the detector is not level with the road surface, the present invention adjusts the position of the support mechanism or manually fills the uneven base so that the two support mechanisms in each group around are in synchronous activity and the detector is adjusted to a state parallel to the road surface, ensuring that the gap between the detector and the road surface will not expand due to tilting, and then ensuring that the detector is parallel to the road surface for vertical compaction detection, thereby ensuring that radioactive elements are not diffused when the compaction is detected vertically in the road surface.

[0019] In the present invention, when the limit groove moves to the triangular groove at the lower end of the blocking plate, the lowermost end of the detector connected to the fixing strip is slightly higher than the lowermost end of the supporting block. At this time, the gap between the detector and the road base is the smallest. At the same time, the detector is slightly higher than the supporting block to ensure that the gap will not cause the detector to touch the gravel on the road base. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] like Figures 1 to 7 As shown, the present invention proposes an intelligent road surface compaction detection device for highway engineering, including a support mechanism 1, a detector 2, a display screen 3, and a controller 4. The controller 4 and the display screen 3 are integrated and installed in the middle of the detector 2. The support mechanism 1 is provided with eight, and every two of the support mechanisms 1 form a group, which are arranged in four groups of squares on the outside of the detector 2. The four groups of support mechanisms 1 support the detector 2 and make the detector 2 parallel to the road surface. When the detector 2 is pressed downward, the support mechanism 1 is against the road surface and slides with the outside of the detector 2;

[0032] The support mechanism 1 is provided with a slide groove 11, a staggered structure 12, a friction plate 13, a power supply 14, and a support block 15. The friction plate 13 is respectively arranged in the two slide grooves 11 on the sides of the support block 15. The power supply 14 is arranged inside the side of the support block 15, and the power supply 14 is electrically connected to the staggered structure 12. The staggered structure 12 connects the inside of every two support blocks 15, and the circuit of the power supply 14 in each support block 15 is connected in series to the staggered structure 12. When the two staggered structures 12 are tilted to the horizontal line, the staggered structure 12 is tilted to disconnect the closed loop formed by the power supply 14.

[0033] In addition, the power supply 14 is provided with a battery and an infrared lamp, and the infrared lamp lights up when the power supply 14 closes the loop and is energized. When the offset structures 12 in two connected power supplies 14 are tilted, the offset structures 12 disconnect the circuit of the power supplies 14. Since the two support blocks 15 of each group are one side outside the detector 2, the power supply 14 in each group of support blocks 15 on the outside can only remain energized when each side of the detector 2 remains horizontal with each other.

[0034] In addition, a fixing bar 16 is provided at the position of the slide groove 11 and connected to the outer side of the detector 2, and the fixing bar 16 slides in the slide groove 11. When the detector 2 is pressed downward, the fixing bar 16 is driven to be squeezed with the friction plate 13, and after the pressing of the detector 2 stops, the fixing bar 16 is fixed against the side of the friction plate 13.

[0035] In addition, a ring-shaped bottom block 151 is provided at the bottom of the support block 15, and the bottom block 151 is made of rubber. When the road surface is curved, the bottom block 151 contacts the road surface in an arc shape, ensuring that the support block 15 contacts the road surface in a vertical state, thereby preventing the uneven road surface from affecting the vertical support of the support block 15.

[0036] Among them, the dislocation structure 12 is provided with a fixed rod 121, a circuit rod 122, a dislocation rod 123, a line box 124, and a square groove 125. The line box 124 is arranged in the square groove 125, and the line box 124 is connected to the line of the power supply 14. The dislocation rod 123 is hinged and rotatably arranged at the upper end of the fixed rod 121. When the two support blocks 15 of each group are horizontal, the dislocation rod 123 maintains a horizontal state, and the left and right ends of the dislocation rod 123 are in contact with the circuit rod 122 in each of the two support blocks 15. When the support block 15 is tilted, the dislocation rod 123 is driven to rotate around the fixed rod 121, and the contact between the left and right ends of the dislocation rod 123 and the circuit rod 122 is released.

[0037] The circuit rod 122 is provided with a circuit contact 1221, a copper wire 1222, and a plastic plate 1223. The two copper wires 1222 are arranged in the plastic plate 1223 and are respectively connected to the positive and negative poles of the circuit box 124, and the two copper wires 1222 are connected to the two circuit contacts 1221.

[0038] In addition, arc-shaped copper end points are provided at the left and right ends of the dislocation rod 123. When the dislocation rod 123 remains stationary, the copper end points contact the two circuit contacts 1221 at the same time, and the two copper wires 1222 are connected in a closed loop.

[0039] In the present invention, the eight supporting mechanisms 1 on the four sides are placed on the road surface through the bottom block 151, and the power supply 14 forms a closed loop with the dislocation structure 12 through the battery. When the detector 2 is pressed close to the road surface and the detector 2 slides in the slide groove 11, when the road surface is uneven, the supporting mechanism 1 has different bearing forces on the horizontal detector 2. The lower position will sink under the pressure of the detector 2 and high and low pressures will appear. At this time, the different bearing forces of the supporting blocks 15 cause different sliding distances with the detector 2. At this time, the two supporting blocks 15 form a height difference, and the fixed rod 121 drives the dislocation rod 123 to rotate with the height difference of the supporting blocks 15, and the left and right ends of the dislocation rod 123 are simultaneously out of contact with the circuit contact 1221 at the position of the circuit rod 122, so The positive and negative poles of the copper wire 1222 are connected to the closed loop of the power supply 14 in the circuit box 124, and at the same time, the infrared lamp in the power supply 14 is no longer lit due to the disconnection of the closed circuit. Since it is known that the detector 2 is not level with the road surface, the effect of turning off the infrared lamp by tilting can intuitively reflect whether the detector 2 is parallel to the road surface. Furthermore, the present invention adjusts the position of the support mechanism 1 or manually fills the uneven base layer so that the two support mechanisms 1 in each group around are in synchronous activity and the detector 2 is adjusted to a state parallel to the road surface, ensuring that the gap between the detector 2 and the road surface will not expand due to the tilt, thereby ensuring that the detector 2 is parallel to the road surface for vertical compaction detection, and ensuring that radioactive elements are not diffused when the compaction is detected perpendicular to the road surface.

[0040] Among them, the friction plate 13 is provided with a connecting plate 131 and a blocking plate 132. The blocking plates 132 are equidistantly arranged on the side of the connecting plate 131. The connecting plate 131 is arranged at the position of the slide groove 11 on the side of the support block 15. The slide groove 11 is provided with a vertical limiting groove 111. When the detector 2 is pressed downward, it drives the fixing bar 16 to move in the slide groove 11 in the support block 15, and makes the fixing bar 16 move vertically in the limiting grooves 111 on both sides of the slide groove 11. At the same time, the fixing bar 16 is pressed against the blocking plate 132. The side of the blocking plate 132 is in a continuous triangular state. When the fixing bar 16 stops moving, it stays in the triangular groove limit formed by the triangular state of the blocking plate 132.

[0041] The friction plates 13 of the eight support blocks 15 of the present invention are against the fixing strips 16, and the individual support blocks 15 of the present invention can be pressed against the road surface under the pressure of the detector 2, and the blocking plate 132 on the side of the connecting plate 131 and the fixing strips 16 are elastically movable under the pressing force, and the fixing strips 16 slide in the limiting grooves 111. When the support blocks 15 are sunk into a lower base layer, the support force under the pressure of the detector 2 is different, and the sunken support blocks 15 have no support force and do not slide with the fixing strips 16. At this time, there is a height difference between the support blocks 15, and the inclination formed by the height difference will be offset by the above-mentioned dislocation structure 12. After the power supply 14 detects that the tilt is detected, the sunken support block 15 is manually pushed, the length of the support block 15 is adjusted, and the sunken position is filled with cornerstones and the detector 2 is pressed again until the detector 2 is close to the road surface and the eight support mechanisms 1 withstand the pressing force and are horizontal to the road surface, thereby ensuring that the detector 2 remains horizontal with the road surface after being pressed. The sliding of the fixed bar 16 and the support block 15 in the present invention is to detect the flatness of the road base layer, to ensure that the base layer is uneven and tilted with the detector 2, in order to detect whether the detector 2 is parallel to the road surface.

[0042] Among them, the fixed bar 16 is provided with a roller 1111, a slide plate 1112, and a connecting block 1113. The slide plate 1112 is arranged on both sides of the connecting block 1113, and balls are arranged on the left and right sides of the slide plate 1112. The slide plate 1112 slides vertically with the inner side of the support block 15 at the position of the limiting groove 111. There are four rollers 1111, which are symmetrically distributed at the upper and lower positions of the side of the connecting block 1113, and the outer layer of the roller 1111 is made of rubber material, which slides and squeezes with the blocking plate 132 to deform. When the fixed bar 16 stops moving, the roller 1111 is supported in a triangular state on the side of the blocking plate 132.

[0043] In addition, the detector 2 is provided with four grooves around it for fingers to be inserted. When the detector 2 is pressed downward, the back of the hand is bent from both sides to press against the plastic plate 1223, and the fingers are inserted into the grooves on both sides of the detector 2, so that the back of the hand supports and fixes the support mechanism 1, and the detector 2 and the support mechanism 1 are vertically slid by the up and down movement of the fingers.

[0044] In the present invention, when the fixed bar 16 slides with the support block 15, the ball on the slide plate 1112 slides in the limiting groove 111, and the limiting groove 111 on 113 rubs against the blocking plate 132, and is blocked by the blocking plate 132 and rolls elastically. When the fixed bar 16 is stationary, the limiting groove 111 is elastically limited in the triangular groove of the blocking plate 132, wherein the limiting groove 111 can only slide elastically on the side of the blocking plate 132. When the limiting groove 111 moves to the triangular groove at the lower end of the blocking plate 132, the lower end of the detector 2 connected to the fixed bar 16 is slightly higher than the lower end of the support block 15. At this time, the gap between the detector 2 and the road base is the smallest. At the same time, the detector 2 is slightly higher than the support block 15, which ensures that the existence of the gap will prevent the detector 2 from touching the gravel on the road base.

[0045] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
