Description

Technical Field

[0001] This utility model relates to the field of road inspection technology, specifically a road deformation detector. Background Technology

[0002] Road deformation refers to various plastic deformation phenomena that occur on the road surface under repeated vehicle loads. It mainly manifests as wavy, rutted, and other morphological changes. In severe cases, it may lead to road collapse. This is mainly due to insufficient shear strength of the road surface, resulting in local plastic deformation when vehicles run over it. It is common at intersections and other locations where frequent lane changes are required. Since road deformation is mostly road surface depression, manual inspection is usually done by visual inspection followed by hand measurement with a ruler. This inspection method has a large error. In order to better detect the amount of road deformation, a road deformation detector is proposed.

[0003] For example, a road deformation detector disclosed in authorization announcement number CN222024851U includes a detection frame, with rollers provided on the lower side of the detection frame via a connecting shaft, a limiting groove provided in the lower part of the detection frame, and a transverse slide seat provided in the limiting groove via a guide rod, with a detection bracket provided on the lower side of the transverse slide seat, and a detection rod elastically sliding inside the detection bracket via a spring and a longitudinal slide seat, with a detection pulley provided on the lower side of the detection rod, and a displacement sensor provided on one side of the longitudinal slide seat, and a motor connected to one end of the connecting shaft via a belt flywheel assembly.

[0004] Although it achieves detection through the detection bracket located on the lower side of the transverse slide in the lower part of the detection frame, the detection bracket has a detection rod and detection pulley elastically slidable inside by springs and longitudinal slides. A displacement sensor is located on one side of the longitudinal slide. When the equipment moves on the detection road, the displacement sensor, detection rod and detection pulley can move up and down according to the degree of deformation of the road surface to perform detection. The detection efficiency is high and the operation is convenient and quick.

[0005] However, the existing detectors do not solve the problems that make it difficult to detect road surface deformation data in multiple locations while on the move, and that it is not easy to fold and store the detector probes for protection or to flexibly adjust and adapt them to detect different road surface locations, thus affecting the flexibility of the detection. Utility Model Content

[0006] The purpose of this invention is to provide a road deformation detector to solve the problems mentioned in the background art, such as the inconvenience of the detector for mobile multi-position detection of road surface deformation data, the difficulty in folding and storing the detection probe for protection and flexible adjustment to adapt to different road surface positions, which affects the flexibility of detection.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A road deformation detector includes a bearing sleeve and a second servo motor. The second servo motor is installed inside the bearing sleeve. A first lead screw is installed at the output end of the second servo motor and is movably connected to the bearing sleeve. The surface of the bearing sleeve is provided with three sets of equally spaced sliding grooves. A slip ring is slidably installed on the outer wall of the bearing sleeve. A first threaded sleeve is provided on the surface of the first lead screw and is threadedly connected to the first lead screw. The first threaded sleeve is slidably connected to the sliding grooves and is connected to the slip ring through the sliding grooves. Three sets of equally spaced connecting arms are movably installed on the side wall of the slip ring. An adjusting arm is movably installed at the end of each connecting arm away from the slip ring.

[0009] Optionally, each of the adjusting arms is provided with a connecting shaft at one end near the bearing sleeve, and the adjusting arm is movably connected to the bearing sleeve through the connecting shaft. Each of the adjusting arms is provided with an integrated frame on its side wall, and a second lead screw is movably installed inside each integrated frame. Each of the integrated frames is provided with a third servo motor on its side wall, and the output end of the third servo motor is connected to the second lead screw.

[0010] Optionally, the surface of the second lead screw is provided with a second threaded sleeve, and the second threaded sleeve is threadedly connected to the second lead screw. A laser rangefinder probe is provided on the side wall of the second threaded sleeve, and a bearing box is provided on the outside of the bearing sleeve.

[0011] Optionally, a storage compartment is provided on the inner wall of the carrier box, and a storage battery is installed inside the carrier box.

[0012] Optionally, an electric push rod is movably installed on the outer wall of the storage compartment, and a push arm is installed at the output end of the electric push rod.

[0013] Optionally, a linkage arm is provided at the end of the push arm away from the electric push rod, and a hinge shaft is provided at the end of the linkage arm near the push arm, and the linkage arm is movably connected to the push arm through the hinge shaft.

[0014] Optionally, a pin is fixedly installed at the end of the linkage arm away from the push arm, and the pin extends into the interior of the storage compartment and is movably connected to the storage compartment, and the pin is connected to the bearing sleeve.

[0015] Optionally, the bottom of the carrier box is symmetrically provided with two sets of support legs, and each support leg is provided with a first servo motor on its side wall.

[0016] Optionally, each of the output ends of the first servo motor is provided with a drive shaft, and each drive shaft is fitted with a traveling wheel.

[0017] Optionally, a control component is provided at the top of the carrier box, and the output end of the control component is electrically connected to the input end of the first servo motor, the electric push rod, the second servo motor, the third servo motor and the laser rangefinder probe.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the detector not only realizes the detection of road surface deformation data in a mobile multi-position manner, but also facilitates the folding, storage and protection of the detection probe and the flexible adjustment to adapt to different road surface positions, and improves the flexibility of detection.

[0019] The device is placed on a road surface. Its electrical components are powered by a battery, and the entire device is controlled by a control unit. A first servo motor drives the traveling wheels via a drive shaft, allowing the device to move on the road. An electric push rod moves the push arm, which in turn drives the linkage arm via a hinge shaft. The linkage arm, in turn, drives the bearing sleeve via a pin shaft, causing the bearing sleeve to rotate out of the storage compartment. A second servo motor drives the first lead screw, which in turn drives a slip ring to slide on the surface of the bearing sleeve. The slip ring drives the connecting arm to rotate, which in turn drives the adjusting arm to rotate around the connecting shaft. The adjusting arm then drives the integrated frame and laser rangefinder probes to rotate, deploying multiple sets of laser rangefinder probes for laser ranging. The probe faces the ground and remains parallel to it. Therefore, the device can use the laser rangefinder probe to detect the distance to the road surface during its movement. If the measured data is greater than the initial data, it indicates that the road surface has collapsed. If the measured data is less than the initial data, it indicates that the road surface has bulged. This allows the device to measure the deformation data of the road surface. The data is transmitted wirelessly to the control component. After the detection is completed, the second servo motor and electric push rod are opened in reverse. The second servo motor drives the adjusting arm, integrated frame and laser rangefinder probe to fold and reset. The electric push rod then drives them to reset into the storage compartment to store and protect the laser rangefinder probe. This enables multi-position detection of road surface deformation data while on the move and facilitates the folding, storage and protection of the detection probe.

[0020] The second lead screw is driven by the third servo motor to rotate, which in turn drives the second threaded sleeve to move. The second threaded sleeve then drives the laser rangefinder probe to move laterally, thereby adjusting the position of the laser rangefinder probe to detect different locations on the road surface. This allows for flexible adjustment and adaptation to detect different road surface locations, improving the flexibility of the detection process. Attached Figure Description

[0035] like Figures 1 to 5As shown, an embodiment of this utility model provides a road deformation detector, including a bearing sleeve 14 and a second servo motor 15. The second servo motor 15 is installed inside the bearing sleeve 14 and serves as the power drive. A first lead screw 17 is installed at the output end of the second servo motor 15 and is movably connected to the bearing sleeve 14. The surface of the bearing sleeve 14 is provided with three sets of equally spaced sliding grooves 27. A slip ring 19 is slidably installed on the outer wall of the bearing sleeve 14. A first threaded sleeve 18 is provided on the surface of the first lead screw 17 and is threadedly connected to the first lead screw 17. The first threaded sleeve 18 is slidably connected to the sliding groove 27 and is connected to the slip ring 19 through the sliding groove 27. Three sets of equally spaced connecting arms 2 are movably installed on the side wall of the slip ring 19. 1. An adjusting arm 22 is movably mounted on the end of the connecting arm 21 away from the slip ring 19. A connecting shaft 20 is provided on the end of the adjusting arm 22 near the bearing sleeve 14. The adjusting arm 22 is movably connected to the bearing sleeve 14 through the connecting shaft 20. An integrated frame 23 is provided on the side wall of the adjusting arm 22. A second lead screw 25 is movably mounted inside the integrated frame 23. A third servo motor 16 is provided on the side wall of the integrated frame 23. The third servo motor 16 plays the role of power drive. The output end of the third servo motor 16 is connected to the second lead screw 25. A second threaded sleeve 26 is provided on the surface of the second lead screw 25. The second threaded sleeve 26 is threadedly connected to the second lead screw 25. A laser rangefinder probe 24 is provided on the side wall of the second threaded sleeve 26. A bearing box 1 is provided on the outside of the bearing sleeve 14.

[0036] The device is placed on the road surface. Its electrical components are powered by a storage battery 4. The control component 3 contains a PLC module, which controls the entire device. Turning on the first servo motor 6 drives the walking wheels 8 via the drive shaft 7, allowing the device to move on the road surface. Turning on the electric push rod 9 moves the push arm 10, which in turn drives the linkage arm 12 via the hinge shaft 11. The linkage arm 12 then drives the bearing sleeve 14 via the pin shaft 13, causing the bearing sleeve 14 to rotate out of the storage compartment 2. After the first lead screw 17 rotates, the second servo motor 15 is activated, which in turn drives the first lead screw 17 to rotate. With the first lead screw 17 threadedly connected to the first threaded sleeve 18, and with the first threaded sleeve 18 slidingly engaged with the sliding groove 27, the first threaded sleeve 18 drives the slip ring 19 to slide on the surface of the bearing sleeve 14. The slip ring 19 then drives the connecting arm 21 to rotate, which in turn drives the adjusting arm 22 to rotate around the connecting shaft 20. The adjusting arm 22 then drives the integrated frame 23 and the laser rangefinder probe 24 to rotate, thus unfolding multiple sets of laser rangefinder probes 24 so that the laser rangefinder probes 24 face the ground and are aligned with the ground. The surfaces remain parallel. The laser rangefinder probe 24 is a product of the same type as the Youyunpu YP-1500. Its working principle is as follows: distance is measured by determining the time from the start of laser emission to its reflection from the target. Multiple laser rangefinder probes 24 measure the distance to the ground. Since road surface deformation is mostly due to road collapse or cracking, the deformed area will bulge or depression, thus changing the distance between the road surface and the laser rangefinder probe 24. Therefore, during the movement of the device, the laser rangefinder probes 24 can detect the distance to the road surface. If the measured data is greater than the initial data, it indicates that the road surface is not parallel. If the surface collapses and the measured data is less than the initial data, it indicates that the road surface has a bulge. This allows for the measurement of road surface deformation data. The data is transmitted wirelessly to the control component 3. After the detection is completed, the second servo motor 15 and the electric push rod 9 are opened in reverse. The second servo motor 15 drives the adjusting arm 22, the integrated frame 23, and the laser rangefinder probe 24 to fold and reset. The electric push rod 9 then drives them to reset inside the storage compartment 2 to store and protect the laser rangefinder probe 24. This enables mobile multi-position detection of road surface deformation data and facilitates the folding, storage, and protection of the detection probe.

[0037] The inner wall of the carrier box 1 is provided with a storage compartment 2, and the inside of the carrier box 1 is provided with a battery 4. An electric push rod 9 is movably installed on the outer wall of the storage compartment 2. The electric push rod 9 plays a power driving role, and a push arm 10 is installed at the output end of the electric push rod 9.

[0038] A linkage arm 12 is provided at the end of the push arm 10 away from the electric push rod 9. A hinge shaft 11 is provided at the end of the linkage arm 12 near the push arm 10, and the linkage arm 12 is movably connected to the push arm 10 through the hinge shaft 11. A pin shaft 13 is fixedly installed at the end of the linkage arm 12 away from the push arm 10, and the pin shaft 13 extends into the interior of the storage compartment 2 and is movably connected to the storage compartment 2. The pin shaft 13 is also connected to the bearing sleeve 14.

[0039] Two sets of support legs 5 are symmetrically arranged at the bottom of the support box 1, and a first servo motor 6 is provided on the side wall of each support leg 5. The first servo motor 6 plays the role of power drive.

[0040] The output end of the first servo motor 6 is equipped with a drive shaft 7, and the surface of the drive shaft 7 is fitted with a walking wheel 8. The top of the carrier box 1 is equipped with a control component 3, and the output end of the control component 3 is electrically connected to the input end of the first servo motor 6, the electric push rod 9, the second servo motor 15, the third servo motor 16 and the laser rangefinder probe 24.

[0041] The third servo motor 16 is turned on, which drives the second lead screw 25 to rotate. With the threaded connection between the second lead screw 25 and the second threaded sleeve 26, the second lead screw 25 drives the second threaded sleeve 26 to move, and the second threaded sleeve 26 drives the laser rangefinder probe 24 to move laterally to adjust the position of the laser rangefinder probe 24, thereby detecting different positions of the road surface. This achieves flexible adjustment and adaptation to detect different road surface positions, improving the flexibility of detection.

[0042] The working principle of the technical solution provided by this utility model is as follows: The device is placed on the road surface. The electrical components in the device are powered by the storage battery 4. The control component 3 contains a PLC component, which controls the entire device. The first servo motor 6 drives the walking wheel 8 to rotate through the drive shaft 7, thus the walking wheel 8 drives the device to move on the road surface. The electric push rod 9 drives the push arm 10 to move. The push arm 10 drives the linkage arm 12 to rotate through the hinge shaft 11. The linkage arm 12 is connected by a pin. Shaft 13 drives the bearing sleeve 14 to rotate, causing the bearing sleeve 14 to rotate out of the storage compartment 2. The second servo motor 15 drives the first lead screw 17 to rotate, and the first threaded sleeve 18 drives the slip ring 19 to slide on the surface of the bearing sleeve 14. The slip ring 19 drives the connecting arm 21 to rotate, and the connecting arm 21 drives the adjusting arm 22 to rotate around the connecting shaft 20. The adjusting arm 22 drives the integrated frame 23 and the laser rangefinder probe 24 to rotate, thereby unfolding multiple sets of laser rangefinder probes 24 and making the laser rangefinder probes 24 face the ground. The device, which is parallel to the ground, can detect the distance to the road surface during its movement using a laser rangefinder probe 24. If the measured data is greater than the initial data, it indicates that the road surface has collapsed; if the measured data is less than the initial data, it indicates that the road surface has bulged. This allows the measurement of road surface deformation data, which is transmitted wirelessly to the control component 3. After the detection is completed, the second servo motor 15 and the electric push rod 9 are opened in reverse. The second servo motor 15 drives the adjusting arm 22, the integrated frame 23, and the laser rangefinder probe 24 to fold and reset. The electric push rod 9 then drives them to reset inside the storage compartment 2 to store and protect the laser rangefinder probe 24. The third servo motor 16 drives the second lead screw 25 to rotate, which in turn drives the second threaded sleeve 26 to move. The second threaded sleeve 26 then moves the laser rangefinder probe 24 to adjust its position laterally, thus allowing for flexible detection of different locations on the road surface. This concludes the entire usage of the road deformation detector.
