Description

Technical Field

[0001] This invention relates to the field of highway testing devices, and more particularly to a testing device for highway engineering. Background Technology

[0002] Highway engineering is a complex and important infrastructure construction project, encompassing the surveying, measurement, design, construction, maintenance and management of multiple structures such as roadbeds, pavements, bridges, and culverts. In recent years, with rapid economic development, the mileage of highway construction has continued to increase, and the quality requirements for highway engineering have also become increasingly stringent.

[0003] Existing highway engineering testing equipment first places the main body of the device above the hole when conducting highway testing. The height of both sides of the main body of the device is adjusted by using a level and screw, so that the probe is vertically downward. The probe is pressed down, and the road surface thickness is observed through a miniature camera and display device. Then, the retaining ring is rotated to rotate the probe and measure the structural thickness at other angles.

[0004] However, existing highway engineering inspection devices cannot adjust the level in two directions during inspection, which easily leads to large imaging errors. Manually controlled rotation results in uneven lens rotation, causing shaking and reducing imaging accuracy. Therefore, it is necessary to provide a highway engineering inspection device that solves the above-mentioned technical problems. Summary of the Invention

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0032] First Embodiment

[0033] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 A highway engineering testing device includes a frame 1, four wheels 2 symmetrically fixedly mounted on the bottom of the frame 1, a handle 3 fixedly mounted on one side of the frame 1, and a leveling mechanism 4.

[0034] The leveling mechanism 4 is fixedly installed on the top of the frame 1. The leveling mechanism 4 includes a base 401. Four bases 401 are fixedly installed on the top of the frame 1. Bearings 402 are fixedly installed on the top of each of the four bases 401. Leveling screws 403 are rotatably installed inside each of the four bearings 402. The four leveling screws 403 are movably connected to each other through a cross-shaped leveling plate 404. The four leveling screws 403 are respectively threaded to the four ends of the cross-shaped leveling plate 404. A round hole 405 is provided in the middle of the cross-shaped leveling plate 404.

[0035] A lifting mechanism 5 is fixedly installed on the top of the cross-shaped adjustment plate 404. The lifting mechanism 5 includes a motor 501, which is fixedly installed on the top of the cross-shaped adjustment plate 404 via a bracket. The output shaft of the motor 501 is fixedly connected to a lifting screw 502. The lifting screw 502 is rotatably installed inside the circular hole 405. A lifting block 503 is threadedly connected to the surface of the lifting screw 502. The lifting block 503 is fixedly connected to a gimbal 505 via a connecting block 504. A laser probe 506 is fixedly installed at one end of the gimbal 505.

[0036] Each of the four leveling screws 403 has a rotating disk 13 fixedly mounted on its top, and the rotating disk 13 is used to rotate the leveling screw 403.

[0037] Two levels 7 are fixedly installed on the top of the cross-shaped adjustment plate 404, and the two levels 7 are installed perpendicular to each other.

[0038] A probe mechanism 6 is fixedly installed on one side of the frame 1. The probe mechanism 6 includes a support plate 601, which is fixedly installed on one side of the frame 1. An electric cylinder 602 is fixedly installed at the bottom of the support plate 601. A probe 603 is fixedly connected to the output end of the electric cylinder 602. A limit post 604 is movably installed on the surface of the probe 603. The top end of the limit post 604 is fixedly installed at the bottom of the support plate 601.

[0039] The surface of the laser probe 506 is provided with a ring light source 11, which is used for illumination inside the hole.

[0040] In actual use, the lifting block 503 is vertically limited by the guide rod;

[0041] The probe 603 has a scale on its surface for workers to read.

[0042] The working principle of the highway engineering testing device provided by this invention is as follows:

[0043] First, the staff pushes the handle 3 to travel on the road surface via the wheel 2. The integrity of the road surface is detected by the vertically downward laser probe 506. When a crack is detected, the electric cylinder 602 is activated to drive the probe 603 downward. The probe 603 stops automatically after encountering resistance at the bottom. After stopping, the staff takes a reading and resets the device. The device continues to move and stops when it moves above the hole.

[0044] Then, after the laser probe 506 is aligned with the hole, the staff observes the bubbles in the two levels 7 and rotates the corresponding rotating disks 13 to drive the leveling screws 403. The leveling screws 403 are threadedly connected to the cross-shaped adjusting plate 404, and the cross-shaped adjusting plate 404 is finely adjusted to be flush with the hole.

[0045] Then, when the two levels 7 show that they are level, the motor 501 is started to drive the lifting screw 502 to rotate. The lifting block 503, which is limited by the guide rod, moves downward. The lifting block 503 drives the gimbal 505 to move downward through the connecting block 504. When the gimbal 505 drives the laser probe 506 to move into the hole, the motor 501 stops.

[0046] Then, the laser probe 506 is rotated from vertical downward to horizontal by the gimbal 505, and the ring light source 11 is turned on to provide supplementary light inside the hole. The gimbal 505 drives the probe to rotate once inside the hole, and the scanning and 3D imaging are completed.

[0047] Finally, after the scanning was completed, staff conducted thickness analysis and analysis of the highway structure.

[0048] Compared with related technologies, the testing device for highway engineering provided by the present invention has the following advantages:

[0049] The laser probe 506 scans the road surface in real time, and the electric cylinder 602 drives the probe 603 to probe downwards, realizing the rapid location and depth measurement of cracks. The gimbal 505 drives the laser probe 506 to rotate and scan, and with the ring light source 11 to supplement the light, a high-resolution three-dimensional model of the hole is generated, which can clearly identify the layered structure and the thickness of the road. After the lifting screw 502 and the leveling screw 403 are leveled, the laser probe 506 is driven to be flush with the hole, realizing vertical lifting and lowering to improve the shooting accuracy.

[0050] Second Embodiment

[0051] Please refer to the following: Figures 5-11 Based on the first embodiment of this application, which provides a testing device for highway engineering, the second embodiment of this application proposes another testing device for highway engineering. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0052] Specifically, the difference in the second embodiment of this application regarding the detection device for highway engineering is that a probing mechanism 8 is fixedly installed at the bottom of the frame 1. The probing mechanism 8 includes a buffer 801, two buffers 801 are symmetrically fixedly installed at the bottom of the frame 1, a bracket 802 is fixedly installed at the bottom of each of the two buffers 801, a connecting rod 803 is fixedly installed between the two brackets 802, a probing wheel 804 is symmetrically fixedly installed on the surface of the connecting rod 803, and a cam 805 is fixedly installed on the surface of the connecting rod 803.

[0053] A spreading mechanism 9 is fixedly installed on one side of the frame 1. The spreading mechanism 9 includes a support plate 901, which is fixedly installed on one side of the frame 1. A limiting plate 902 is fixedly installed at the bottom of the support plate 901. A push block 904 is slidably connected to the limiting plate 902 via a connecting column 903. A support plate 905 is fixedly installed at the bottom of the support plate 901. A return spring 909 is fixedly installed at the bottom of the support plate 901 via a bracket. A drive block 906 is fixedly connected to one end of the return spring 909. The support plate 905 is slidably connected to the transverse groove of the drive block 906. The drive block 906 is adapted to be installed with the push block 904. A toothed plate 1 907 and a toothed plate 2 908 are fixedly installed on the top of the drive block 906.

[0054] The cam 805 is fitted and installed in conjunction with the pusher block 904 to push the pusher block 904 to move.

[0055] A powder storage mechanism 10 is symmetrically fixedly installed on both sides of the support plate 901. The powder storage mechanism 10 includes a powder storage bin 1001. Two powder storage bins 1001 are fixedly installed on both sides of the support plate 901. The top of the powder storage bin 1001 is connected to a feed inlet 1002. A rotating shaft 1003 is rotatably installed on the inner wall of the powder storage bin 1001. Both ends of the rotating shaft 1003 pass through the powder storage bin 1001 and extend to the outside. A rotating plate 1004 is fixedly installed on the surface of the rotating shaft 1003. The rotating plate 1004 is adapted to the powder storage bin 1001. A gear 1005 is fixedly installed on one end of the rotating shaft 1003 located outside the powder storage bin 1001. The two gears 1005 mesh with the first gear plate 907 and the second gear plate 908, respectively.

[0056] A powder baffle plate 12 is fixedly installed at the bottom of the frame 1. The powder baffle plate 12 is adapted to the laser probe 506 and is used to prevent the laser probe 506 from being contaminated with talcum powder.

[0057] In actual use, the probing mechanism 8 can be adjusted according to the road surface undulation standards of different grades of highways;

[0058] The powder storage bin 1001 on the right is filled with white talc powder;

[0059] The powder storage bin 1001 on the left is filled with red talc powder;

[0060] The two powder storage mechanisms 10 are adapted and installed to the frame 1;

[0061] The toothed plate 907 meshes with the gear 1005 on the right side;

[0062] The toothed plate 908 meshes with the gear 1005 on the left side;

[0063] The toothed plate 907 initially engages with the gear 1005 on the right side, and the toothed plate 908 initially engages with the gear 1005 on the left side after being positioned in the center of the drive block 906.

[0064] The working principle of the highway engineering testing device provided in this embodiment is as follows:

[0065] First, the staff pushes the device to move. When encountering minor road undulations, the two probe wheels 804 push the connecting rod 803 upward. The connecting rod 803 drives the cam 805 to push the push block 904 upward. The push block 904 is vertically limited by the limiting plate 902. During the upward movement, the push block 904 pushes the drive block 906 to move horizontally. The drive block 906 is limited by the support plate 905. During the horizontal movement, the toothed plate 907 meshes with the right gear 1005, which drives the rotating plate 1004 to open and sprinkle white talcum powder for marking.

[0066] Then, after the probe wheel 804 leaves the uneven surface, the return spring 909 drives the drive block 906 to reset. During the reset process, the toothed plate 907 re-engages the right gear 1005, causing the rotating plate 1004 to close.

[0067] Then, when the road surface of the probe wheel 804 is uneven and bumpy, the two probe wheels 804 push the connecting rod 803 upward to a higher distance. At this time, the push block 904 moves upward more, and the drive block 906 moves horizontally a greater distance. At this time, the toothed plate 908 meshes with the gear 1005 on the left side, which drives the rotating plate 1004 to open and sprinkle red talcum powder for marking. After the work is completed, the above process is repeated to reset.

[0068] Finally, after the device has been working for a period of time, when the red and white talc powder in the two powder storage tanks 1001 are used up, the material is replenished through the feed inlet 1002.

[0069] The powder-blocking plate 12 is used to block the talcum powder and prevent it from affecting the laser probe 506.

[0070] Compared with related technologies, the testing device for highway engineering provided in this embodiment has the following advantages:

[0071] When the probe wheel 804 encounters road undulations of varying sizes, it pushes the push block 904 upwards to open the powder storage bins 1001 on both sides, allowing for the application of white and red-white talcum powder respectively. This more clearly distinguishes the severity levels, facilitating maintenance by staff and improving detection efficiency. The red talcum powder serves as a warning of high-risk areas to prevent delays in processing. The powder baffle 12 prevents the talcum powder from affecting the normal operation of the laser probe 506. The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
