Description

Technical Field

[0001] The present invention relates to the technical field of compaction detection, in particular to a road compaction detection device. Background Art

[0002] Compaction degree is one of the key indicators for roadbed and pavement construction quality inspection, which characterizes the density condition after on-site compaction. The higher the compaction degree, the greater the density and the better the overall performance of the material. The methods for compaction degree inspection include: sand filling method, ring knife method, water filling method, direct weighing method, core drilling method, wax sealing method, etc. Among them, the core drilling method is also a relatively commonly used inspection method.

[0003] The core drilling method uses a special drill to drill core samples from structural concrete to test the concrete strength or observe the internal quality of the concrete. This method causes dust to float into the air during use, which needs to be cleaned up by workers later, causing certain troubles to the workers. At the same time, some energy is wasted during the high-intensity rotation of the drill barrel, and the energy utilization efficiency is not high. Summary of the Invention

[0004] The purpose of the present invention is to provide a road compaction detection device to solve the problems raised in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A technical solution for a road compaction detection device, the detection device including a detection base, a drive device, a sampling device, a dustproof device, a dust removal device and a stabilizing device, the detection base and the drive device are tightly connected, the detection base and the dustproof device are tightly connected, the detection base and the dust removal device are tightly connected, the detection base and the stabilizing device are tightly connected, the drive device and the sampling device are tightly connected, a steering pulley is provided on the detection base, and the steering pulley and the detection base are tightly connected.

[0007] The detection base serves as the main installation foundation for the installation and fixation of other devices. The stabilizing device is used to stabilize the entire device to prevent the device from moving during the sampling process. The sampling device is pushed into the ground road for sampling through the driving device. At the same time, the sampling device samples the ground road by rotating. During the sampling process, the rotation of the sampling device itself is converted into electric current through electromagnetic induction, which is used as energy to assist the dust removal device, thereby achieving energy conservation and emission reduction. At the same time, the dust generated during the sampling process is processed through the dust prevention device and the dust removal device to prevent the dust from spreading to the road surface, reducing the difficulty of dust processing in the later stage and improving the sampling efficiency.

[0008] Furthermore, the detection base is also provided with a dustproof mounting groove, a dust removal groove and a mounting hole, the dustproof device is connected to the dustproof mounting groove, the input end of the dust removal device is connected to the dust removal groove, and the stabilizing device is firmly connected to the mounting hole.

[0009] The dustproof installation groove provides an installation position for the dustproof device, the dust removal groove and the dust removal device are connected to send dust into the dust removal device through the dust removal groove, and the installation hole provides an installation position for the stabilization device, which facilitates the stabilization device to function.

[0010] Furthermore, the driving device includes a driving support plate, a driving cylinder, a driving slide rail and a driving connecting plate. The driving support plate is tightly connected to the detection base, the driving support plate is tightly connected to the driving cylinder, the driving support plate is tightly connected to the driving slide rail, the driving cylinder is tightly connected to the driving connecting plate, the driving slide rail is tightly connected to the driving connecting plate at one end away from the driving support plate, and the driving connecting plate is tightly connected to the sampling device.

[0011] The driving support plate serves as the main support for supporting other components. The driving cylinder outputs displacement to drive the driving connecting plate to move along the driving slide rail, and the driving slide rail moves to drive the sampling device, so that the displacement output by the driving cylinder drives the sampling device to move, so that the driving cylinder can push the sampling device into the ground road for sampling.

[0012] Furthermore, the sampling device includes a sampling support plate, a sampling motor, a connecting tube and a sampling drill tube. The sampling support plate and the driving connecting plate are tightly connected, the sampling support plate and the sampling motor are tightly connected, the output end of the sampling motor and the connecting tube are tightly connected, the connecting tube and the sampling drill tube are tightly connected, and the connecting tube and the dust removal device are electrically connected.

[0013] The sampling support plate serves as the main installation base and is used to support and install other components. When sampling of the ground road is required, the sampling motor outputs a rotational torque to drive the connecting tube to rotate rapidly, and the rapid rotation of the connecting tube drives the sampling drill tube to rotate rapidly. At the same time, the driving cylinder outputs a displacement to drive the sampling support plate to move. The movement of the sampling support plate drives the movement of the sampling motor. The movement of the sampling motor drives the connecting tube to move. The movement of the connecting tube drives the sampling drill tube to move, so that the displacement output by the driving cylinder drives the sampling drill tube to move. Through the movement and rotation of the sampling drill tube, the sampling drill tube can be rotated downward to perform sampling and detection on the ground road.

[0014] Furthermore, the sampling device also includes a sampling connecting plate, which is tightly connected to the sampling support plate. A magnet is provided on the sampling connecting plate. There are two sampling connecting plates, which are relatively installed on the sampling support plate. A coil mounting cavity is provided in the connecting tube, and an electromagnetic coil is provided in the coil mounting cavity. The electromagnetic coil is perpendicular to the magnetic field formed by the magnet.

[0015] The sampling connecting plate provides an installation base for the magnet, so that the magnetic field plane generated by the magnet is perpendicular to the electromagnetic coil in the coil installation cavity. When the sampling motor outputs the rotational torque, the sampling motor causes the connecting tube to rotate, and the rotation of the connecting tube drives the electromagnetic coil in the coil installation cavity to rotate. The change in magnetic flux formed by the magnetic field formed by the rotation of the electromagnetic coil cuts the magnet to generate current. The connecting tube and the dust removal device are electrically connected so that the electric energy generated by electromagnetic induction can drive the dust removal device to work, thereby improving energy utilization efficiency and saving energy consumption.

[0016] Furthermore, the dustproof device includes a first dustproof plate, a first dustproof cylinder, a first baffle, a second dustproof plate, a second dustproof cylinder and a second baffle. The first dustproof plate and the first dustproof cylinder are tightly connected, the first dustproof plate and the detection base are slidingly connected, the first baffle and the output end of the first dustproof cylinder are tightly connected, the first baffle and the detection base are tightly connected, the second dustproof plate and the detection base are slidingly connected, the output end of the second dustproof cylinder and the second baffle are tightly connected, the second baffle and the second dustproof plate are tightly connected, the second dustproof cylinder is placed in the dustproof mounting groove, and the second dustproof cylinder and the dustproof mounting groove are tightly connected.

[0017] When the driving cylinder outputs displacement, the first dust-proof cylinder outputs displacement and acts on the first baffle. Since the first baffle is fixed on the detection base, the first dust-proof cylinder is subjected to a reaction force, and the reaction force causes the first dust-proof cylinder to move. The movement of the first dust-proof cylinder drives the first dust-proof plate to move along the detection base until the first dust-proof plate moves to the specified position and the first dust-proof cylinder stops outputting displacement. At the same time as the first dust-proof cylinder outputs displacement, the second dust-proof cylinder outputs displacement to drive the second baffle to move. The movement of the second baffle drives the second dust-proof plate to move until the second dust-proof plate moves to the working position. The second dust-proof cylinder stops outputting displacement, and the dust generated by the sampling drill barrel during operation is limited to the space range formed by the second dust-proof plate and the first dust-proof plate through the second dust-proof plate and the first dust-proof plate, so that the dust will not spread to other locations on the road.

[0018] Furthermore, the dust removal device is used to provide negative pressure to the dust removal trough, and a driving energy source and a dust storage box are provided in the dust removal device.

[0019] The dust removal device provides negative pressure to the dust removal groove, so that the dust removal device can suck the dust generated during the operation of the sampling drill barrel into the dust storage box through the dust removal groove, and the dust removal device is driven to work at the same time by the driving energy and the induced current generated on the connecting tube, thereby improving the energy utilization efficiency.

[0020] Furthermore, the stabilizing device includes a stabilizing cylinder and a stabilizing disc. The stabilizing cylinder is placed in the mounting hole. The stabilizing cylinder and the mounting hole are fastened together. The output end of the stabilizing cylinder and the stabilizing disc are fastened together.

[0021] The stabilizing cylinder outputs displacement to drive the stabilizing disc until the stabilizing disc is in stable contact with the ground. The stabilizing cylinder then stops outputting displacement, increasing the adhesion of the entire device to the ground through the stabilizing disc, preventing the entire device from moving during operation and affecting work efficiency.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. A stabilizing device is provided to improve the stability of the detection device during the sampling process. The stabilizing device increases the force between the detection device and the ground, so that the detection device will not move.

[0024] 2. It improves the efficiency of energy utilization. The electromagnetic coil set in the connecting cylinder generates electromagnetic induction through the electromagnetic coil and the magnet. The generated induced current is used for energy recovery. The recovered energy is used to assist the dust removal device to work, saving energy and achieving energy-saving effects.

[0025] 3. A dust removal device is set up, which can effectively remove the dust generated by the device during the sampling process, preventing the dust from falling to various places on the road during the sampling process, causing trouble for subsequent processing work.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0036] Example: Figure 1 - Figure 8 As shown, the present invention provides a technical solution for a road compaction detection device, the detection device includes a detection base 1, a driving device 2, a sampling device 3, a dust-proof device 4, a dust removal device 5 and a stabilizing device 6, the detection base 1 and the driving device 2 are tightly connected, the detection base 1 and the dust-proof device 4 are tightly connected, the detection base 1 and the dust removal device 5 are tightly connected, the detection base 1 and the stabilizing device 6 are tightly connected, the driving device 2 and the sampling device 3 are tightly connected, and a steering pulley 7 is provided on the detection base 1, and the steering pulley 7 and the detection base 1 are tightly connected.

[0037] The detection base 1 is used as the main installation basis for the installation and fixation of other devices.

The sampling device 3 is pushed into the ground road for sampling by the driving device 2. At the same time, the sampling device 3 samples the ground road by rotating. During the sampling process, the rotation of the sampling device 3 itself is converted into electric current through electromagnetic induction, which is used as energy to assist the dust removal device 5 to achieve energy saving and emission reduction. At the same time, the dust generated during the sampling process is processed by the dust prevention device 4 and the dust removal device 5 to prevent the dust from spreading to the road surface, reducing the difficulty of dust processing in the later stage and improving the sampling efficiency.

[0039] The dustproof mounting groove 11 provides an installation position for the dustproof device 4, and the dust removal groove 12 is connected to the dust removal device 5 to send dust into the dust removal device 5 through the dust removal groove 12. The mounting hole 13 provides an installation position for the stabilizing device 6, which facilitates the stabilizing device 6 to function.

[0040] like Figure 1-Figure 3 As shown, the driving device 2 includes a driving support plate 21, a driving cylinder 22, a driving slide rail 23 and a driving connecting plate 24. The driving support plate 21 is tightly connected to the detection base 1, the driving support plate 21 is tightly connected to the driving cylinder 22, the driving support plate 21 is tightly connected to the driving slide rail 23, the driving cylinder 22 is tightly connected to the driving connecting plate 24, the driving slide rail 23 is tightly connected to the driving connecting plate 24 at one end away from the driving support plate 21, and the driving connecting plate 24 is tightly connected to the sampling device 3.

[0041] The driving support plate 21 serves as the main support for supporting other components. The driving cylinder 22 outputs displacement to drive the driving connecting plate 24 to move along the driving slide rail 23, and the movement of the driving slide rail 23 drives the sampling device 3 to move, so that the displacement output by the driving cylinder 22 drives the sampling device 3 to move, so that the driving cylinder 22 can push the sampling device 3 into the ground road for sampling.

[0042] like Figure 1-Figure 4 As shown, the sampling device 3 includes a sampling support plate 31, a sampling motor 32, a connecting tube 33 and a sampling drill tube 34. The sampling support plate 31 and the driving connecting plate 24 are tightly connected, the sampling support plate 31 and the sampling motor 32 are tightly connected, the output end of the sampling motor 32 and the connecting tube 33 are tightly connected, the connecting tube 33 and the sampling drill tube 34 are tightly connected, and the connecting tube 33 and the dust removal device 5 are electrically connected.

[0043] The sampling support plate 31 serves as the main installation base, and is used to support and install other components. When sampling of the ground road is required, the sampling motor 32 outputs a rotational torque to drive the connecting tube 33 to rotate rapidly, and the rapid rotation of the connecting tube 33 drives the sampling drill tube 34 to rotate rapidly. At the same time, the driving cylinder 22 outputs a displacement to drive the sampling support plate 31 to move. The movement of the sampling support plate 31 drives the movement of the sampling motor 32. The movement of the sampling motor 32 drives the connecting tube 33 to move. The movement of the connecting tube 33 drives the sampling drill tube 34 to move, so that the displacement output by the driving cylinder 22 drives the sampling drill tube 34 to move. Through the movement and rotation of the sampling drill tube 34, the sampling drill tube 34 can be rotated downward to perform sampling and detection on the ground road.

[0044] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 8 As shown, the sampling device 3 also includes a sampling connecting plate 35, which is tightly connected to the sampling support plate 31. A magnet 36 is provided on the sampling connecting plate 35. There are two sampling connecting plates 35, which are relatively mounted on the sampling support plate 31. A coil mounting cavity 331 is provided in the connecting tube 33, and an electromagnetic coil is provided in the coil mounting cavity 331. The electromagnetic coil is perpendicular to the magnetic field formed by the magnet 36.

[0045] The sampling connecting plate 35 provides an installation base for the magnet 36, so that the magnetic field plane generated by the magnet 36 is perpendicular to the electromagnetic coil in the coil mounting cavity 331. When the sampling motor 32 outputs a torque, the sampling motor 32 causes the connecting tube 33 to rotate, and the rotation of the connecting tube 33 drives the electromagnetic coil in the coil mounting cavity 331 to rotate. The change in magnetic flux formed by the magnetic field formed by the rotation of the electromagnetic coil cutting the magnet 36 generates current. The electrical connection between the connecting tube 33 and the dust removal device 5 allows the electric energy generated by electromagnetic induction to drive the dust removal device 5 to work, thereby improving energy utilization efficiency and saving energy consumption.

[0046] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 7 and Figure 8 As shown, the dustproof device 4 includes a first dustproof plate 41, a first dustproof cylinder 42, a first baffle 43, a second dustproof plate 44, a second dustproof cylinder 45 and a second baffle 46. The first dustproof plate 41 and the first dustproof cylinder 42 are fastened together, the first dustproof plate 41 and the detection base 1 are slidingly connected, the first baffle 43 and the output end of the first dustproof cylinder 42 are fastened together, the first baffle 43 and the detection base 1 are fastened together, the second dustproof plate 44 and the detection base 1 are slidingly connected, the output end of the second dustproof cylinder 45 is fastened together and the second baffle 46 is fastened together, the second baffle 46 and the second dustproof plate 44 are fastened together, the second dustproof cylinder 45 is placed in the dustproof mounting groove 11, and the second dustproof cylinder 45 and the dustproof mounting groove 11 are fastened together.

[0047] When the driving cylinder 22 outputs displacement, the first dustproof cylinder 42 outputs displacement to act on the first baffle 43. Since the first baffle 43 is fixed on the detection base 1, the first dustproof cylinder 42 is subjected to a reaction force, and the reaction force causes the first dustproof cylinder 42 to move. The movement of the first dustproof cylinder 42 drives the first dustproof plate 41 to move along the detection base 1 until the first dustproof plate 41 moves to the specified position and the first dustproof cylinder 42 stops outputting displacement. At the same time as the first dustproof cylinder 42 outputs displacement, the second dustproof cylinder 45 outputs displacement to drive the second baffle 46 to move. The movement of the second baffle 46 drives the second dustproof plate 44 to move until the second dustproof plate 44 moves to the working position. The second dustproof cylinder 45 stops outputting displacement, and the dust generated by the sampling drill barrel 34 during operation is limited to the space range formed by the second dustproof plate 44 and the first dustproof plate 41 through the second dustproof plate 44 and the first dustproof plate 41, so that the dust will not spread to other positions on the road.

[0048] like Figure 2 and Figure 5 As shown, the dust removal device 5 is used to provide negative pressure to the dust removal trough 12, and a driving energy source and a dust storage box are provided in the dust removal device 5.

[0049] The dust removal device 5 provides negative pressure to the dust removal groove 12, so that the dust removal device 5 can suck the dust generated during the operation of the sampling drill tube 34 into the dust storage box through the dust removal groove 12, and the dust removal device 5 is driven to work at the same time by the driving energy and the induced current generated on the connecting tube 33, thereby improving the energy utilization efficiency.

[0050] like Figure 1 and Figure 2 As shown, the stabilizing device 6 includes a stabilizing cylinder 61 and a stabilizing disc 62 . The stabilizing cylinder 61 is placed in the mounting hole 13 . The stabilizing cylinder 61 and the mounting hole 13 are fastened together. The output end of the stabilizing cylinder 61 and the stabilizing disc 62 are fastened together.

[0051] The stabilizing cylinder 61 outputs displacement to drive the stabilizing disc 62 until the stabilizing disc 62 is in stable contact with the ground. The stabilizing cylinder 61 stops outputting displacement, and the stabilizing disc 62 increases the adhesion of the entire device to the ground, preventing the entire device from moving during operation and affecting work efficiency.

[0052] The working principle of the present invention is as follows: the driving cylinder 22 outputs displacement to drive the driving connecting plate 24 to move along the driving slide rail 23, and the driving slide rail 23 moves to drive the sampling support plate 31 to move, and the movement of the sampling support plate 31 drives the sampling motor 32 to move, and the movement of the sampling motor 32 drives the connecting tube 33 to move, and the movement of the connecting tube 33 drives the sampling drill tube 34 to move, and at the same time, the sampling motor 32 outputs a rotational torque to drive the connecting tube 33 to rotate rapidly, and the rapid rotation of the connecting tube 33 drives the sampling drill tube 34 to rotate rapidly, and the movement of the sampling drill tube 34 and The rotation allows the sampling drill tube 34 to rotate downward to sample and detect the ground road. While the driving cylinder 22 outputs displacement, the first dustproof cylinder 42 outputs displacement to act on the first baffle 43. Since the first baffle 43 is fixed on the detection base 1, the first dustproof cylinder 42 is subjected to a reaction force, which causes the first dustproof cylinder 42 to move. The movement of the first dustproof cylinder 42 drives the first dustproof plate 41 to move along the detection base 1 until the first dustproof plate 41 moves to the specified position. The first dustproof cylinder 42 stops outputting. Displacement, while the first dust-proof cylinder 42 outputs displacement, the second dust-proof cylinder 45 outputs displacement to drive the second baffle 46 to move, and the movement of the second baffle 46 drives the second dust-proof plate 44 to move until the second dust-proof plate 44 moves to the working position, and the second dust-proof cylinder 45 stops outputting displacement. The dust generated by the sampling drill barrel 34 during operation is confined to the space formed by the second dust-proof plate 44 and the first dust-proof plate 41 through the second dust-proof plate 44 and the first dust-proof plate 41, so that the dust will not spread to other locations on the road. During the rotation of the connecting tube 33, the electromagnetic coil in the coil mounting cavity 331 is driven to rotate by the rotation of the connecting tube 33. The change in magnetic flux formed by the magnetic field formed by the cutting magnet 36 through the rotation of the electromagnetic coil generates current. The dust removal device 5 is driven to work simultaneously by the driving energy and the induced current generated on the connecting tube 33, thereby improving the energy utilization efficiency. The dust removal device 5 can absorb the dust generated by the sampling drill barrel 34 during operation into the dust storage box through the dust removal groove 12, thereby improving the energy utilization efficiency and saving energy consumption.
