Description

Technical Field

[0001] This utility model is a ground-penetrating radar detection device for bridge approach slabs, belonging to the field of bridge approach detection. Background Technology

[0002] With the rapid construction of my country's high-grade highway network, bridge approach slab settlement has become a key issue restricting road traffic quality. As an important transitional structure connecting bridges and roadbeds, bridge approach slabs commonly suffer from subsidence, voids, and fractures during long-term service. Data shows that over 60% of operational highways experience significant deformation with slab settlement exceeding 30mm within five years of opening, seriously threatening driving safety and comfort. These problems not only affect driving comfort but may also pose a threat to the safety of pedestrians and vehicles. Therefore, technicians need to conduct defect detection on bridge approach slabs to determine if road repairs are necessary. Generally, technicians use radar to inspect the road surface.

[0003] For example, when inspecting existing road surfaces, a mobile chassis is typically used. The radar unit is mounted on the chassis, and the chassis moves the radar unit, allowing it to inspect the road surface as it moves. However, during inspection, the road surface may contain gravel or mud. When the detector is being moved to inspect for road defects, it is obstructed by the gravel or mud, causing the detector to shake during movement. This reduces the detector's accuracy and affects the results of the road defect inspection. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a ground-penetrating radar detection device for bridge approach slabs.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A ground-penetrating radar detection device for bridge approach slabs includes a pushing component, a connecting component, and an installation component. The pushing component is connected to the installation component via the connecting component. The pushing component includes a pushing plate, and the installation component includes an installation plate. A radar body is fixedly mounted on the installation plate in conjunction with a fixing component. Transport wheels are provided at the bottom ends of both the pushing plate and the installation plate. A slag hopper is connected to the front of the installation plate in conjunction with a lifting component. The lifting component includes a fixing frame fixed to the installation plate. An electric telescopic rod is fixedly mounted on the fixing frame. A connecting plate is fixedly mounted at the bottom output end of the electric telescopic rod. The slag hopper is fixedly mounted on the connecting plate. A cleaning component is provided on the fixing frame.

[0007] Furthermore, the cleaning assembly includes a vertical plate, on the side of the vertical plate facing the slag hopper, two fixed plates are fixedly mounted, each fixed plate is embedded with a bearing, and a rotating rod is rotatably connected between the fixed plates in cooperation with the bearing. The rotating rod is hollow inside, and a cleaning component is provided on the outer surface of the rotating rod. A drive assembly is provided on one of the fixed plates, a stop block is fixed on the fixed frame, and a threaded plate is fixed at the top of the fixed frame. Corresponding threaded holes are opened on the threaded plate and the vertical plate.

[0008] Furthermore, the drive assembly includes a drive motor and a reducer. The output end of the drive motor is connected to the reducer, and the reducer's reduction end rod passes through the fixed plate and connects to the rotating rod.

[0009] Furthermore, the cleaning component includes two semi-circular plates, on which bristles are evenly arranged. The semi-circular plates are fitted onto the rotating rod and fixed with screws.

[0010] Furthermore, the connecting components are all mating plates fixed on the push plate and the mounting plate, and the mating plates are fixed together with screws.

[0011] Furthermore, the fixing components include heat dissipation slots formed on the mounting plate and two clamping members. Two support plates supporting the radar body are fixedly installed in the heat dissipation slots, and each clamping member includes a dual-axis lead screw, with clamping plates threaded onto both ends of the dual-axis lead screw.

[0012] Furthermore, the mounting plate has an arrangement slot for arranging the dual-axis lead screw. One end of the dual-axis lead screw is rotatably mounted in the arrangement slot with the auxiliary bearing, and the other end of the dual-axis lead screw is fixed with a manual turntable. The inner wall of the heat dissipation slot has a transverse sliding groove for the clamping plates to pass through. The transverse sliding groove and the arrangement slot are connected. The total number of clamping plates is four.

[0013] Furthermore, two setting plates are fixedly installed at the top of the mounting plate. Threaded rods are threaded through the setting plates, with one end of the threaded rod connected to a push block. A cylinder is fixedly installed on the push block, and a T-shaped rotating groove is opened inside the cylinder.

A secondary threaded rod is threaded through the top of the push block, and a manual turntable is fixedly installed on both the threaded rod and the secondary threaded rod.

[0014] The beneficial effects of this utility model are:

[0015] When installing the radar unit using fixed components, technicians push the push plate while inspecting road surface defects. The radar unit then inspects the road surface. This stable installation method ensures high stability of the radar unit and guarantees that the radar unit can be disassembled and reconnected later, ensuring repairability in case of damage.

[0016] With the cleaning component, when the transport wheel is transporting the entire equipment, the gravel in front is swept into the slag hopper, so that the radar body can maintain a stable speed during detection, reduce the shaking caused by gravel on the road surface, and thus improve the accuracy of radar body detection.

[0017] The electric telescopic rod lowers the slag hopper and cleaning components, allowing the slag hopper to contact the ground and thus enabling the device to move forward more easily. When encountering immovable obstacles, such as at slope junctions, the slag hopper and cleaning components are raised, allowing the detection device to continue moving normally. This utility model has a simple design, ensures stable use of the device, and guarantees that the entire device can move normally even when encountering obstacles, thus improving the device's practicality.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 This utility model provides a ground-penetrating radar detection device for bridge approach slabs, including a pushing component, a connecting component, and an installation component. The pushing component is connected to the installation component through the connecting component. The pushing component includes a pushing plate 1, and the installation component includes an installation plate 2. A radar body 3 is fixedly mounted on the installation plate 2 in conjunction with a fixing component. Transport wheels 4 are provided at the bottom ends of both the pushing plate 1 and the installation plate 2. A slag hopper 5 is connected to the front of the installation plate 2 in conjunction with a lifting component. The lifting component includes a fixing frame 6 fixed on the installation plate 2. An electric telescopic rod 7 is fixedly mounted on the fixing frame 6. A connecting plate 8 is fixedly mounted at the output bottom end of the electric telescopic rod 7. The slag hopper 5 is fixedly mounted on the connecting plate 8. A cleaning component is provided on the fixing frame 6.

[0027] See Figure 1The cleaning assembly includes a vertical plate 9. Two fixed plates 10 are fixed to the side of the vertical plate 9 facing the slag hopper 5. Each fixed plate 10 has an embedded bearing 11. A rotating rod 12 is rotatably connected between the fixed plates 10 in cooperation with the bearings 11. The rotating rod 12 is hollow inside, and a cleaning component is provided on its outer surface. A drive assembly is provided on one of the fixed plates 10. A connecting plate 8 and the vertical plate 9 are fixedly connected. A stop block 31 is fixed on a fixing frame 6. A threaded plate 32 is fixed to the top of the fixing frame 6. Corresponding threaded holes 33 are formed on the threaded plate 32 and the vertical plate 9. The threaded plate 32 has one threaded hole 33, and the vertical plate 9 has two threaded holes 33. When the slag hopper 5 rises or falls normally, after rising or falling to the appropriate position, the abutment block 31 contacts the connecting plate 8, indicating that the slag hopper 5 can no longer rise. One of the threaded holes 33 on the vertical plate 9 corresponds to the threaded hole 33 on the threaded plate 32. By inserting a screw, the vertical plate 9 can be fixed, and the slag hopper 5 can be raised and suspended in the air, avoiding the need for a single electric telescopic rod to support the slag hopper 5. When the vertical plate 9 can no longer fall, it means that the slag hopper 5 has just touched the ground. At this time, the other threaded hole 33 on the vertical plate 9 corresponds to the threaded hole 33 on the threaded plate 32. With the screw inserted, the slag hopper 5 can be kept in contact with the ground. The bottom surface of the slag hopper 5 and the bottom surface of the transport wheel 4 are on the same horizontal plane.

[0028] See Figure 2-3 The drive assembly includes a drive motor and a reducer 13. The output end of the drive motor is connected to the reducer 13. The reduction end rod of the reducer 13 passes through the fixed plate 10 and connects to the rotating rod 12. The cleaning component includes two semi-circular plates 14, on which bristles are evenly arranged. The semi-circular plates 14 are fitted onto the rotating rod 12 and fixed with screws, driving the rotating rod 12 and its bristles to rotate, thus driving the bristles to sweep the ground. The swept material is then swept into the slag hopper 5.

[0029] See Figure 1 , Figure 4 and Figure 5The connecting components are all mating plates 15 fixed on the push plate 1 and the mounting plate 2. The mating plates 15 are fixed together with screws. The fixing components include heat dissipation slots 16 and two clamping parts on the mounting plate 2. Two support plates 17 supporting the radar body 3 are fixed in the heat dissipation slots 16. The clamping parts all include double-axis lead screws 18. Clamping plates 19 are threaded on both ends of the double-axis lead screws 18. The mounting plate 2 has a layout slot 30 for arranging the double-axis lead screws 18. One end of the double-axis lead screw 18 is rotatably mounted in the layout slot 30 with the auxiliary bearing. The other end of the double-axis lead screw 18 is fixed with a manual turntable 20. The inner wall of the heat dissipation slot 16 has a transverse sliding groove 21 for the clamping plates 19 to pass through. The transverse sliding groove 21 and the layout slot 30 are connected. There are a total of four clamping plates 19. Two setting plates 22 are also fixed on the top of the mounting plate 2. Threaded rods 23 are threaded through the setting plates 22. One end of the threaded rods 23 is connected to A push block 24 is fixedly mounted with a cylinder 25. A T-shaped rotating groove 29 is formed inside the cylinder 25. One end of a threaded rod 23 is a T-shaped end and is movably positioned within the T-shaped rotating groove 29. A traction groove 26 is formed at the top of the mounting plate 2. A slider 27, which passes through the traction groove 26, is fixedly mounted at the bottom of the push block 24. A secondary threaded rod 28 is threaded through the top of the push block 24. Both the threaded rod 23 and the secondary threaded rod 28 are fixedly mounted with manual turntables. The radar body 3 is supported on the support plate 17. Then, the dual-axis lead screw 18 is rotated, causing its two clamping plates 19 to clamp the two sides of the radar body 3. Next, the threaded rod 23 is rotated, causing it to engage with the cylinder 25, pushing the push block 24 to clamp the other side wall of the radar body 3. Finally, the secondary threaded rod 28 is rotated, causing it to press down on the top of the radar body 3, completing the comprehensive clamping of the radar body 3 and ensuring the stability of the detection.

[0030] When the radar body 3 is installed using the fixed components, technicians push the push plate 1 to inspect the road surface for defects. This stable installation method ensures the radar body is securely installed and allows for subsequent detachment and repair. The cleaning component sweeps away gravel into the slag hopper 5 as the transport wheels 4 move the entire device, maintaining a stable speed and reducing vibration caused by gravel, thus improving detection accuracy. The electric telescopic rod 7 lowers the slag hopper 5 and cleaning component, allowing the slag hopper 5 to contact the ground for easier movement. When encountering immovable obstacles, such as at slope junctions, the slag hopper 5 and cleaning component are raised to allow the detection device to continue moving normally. This invention is simple in design, ensures stable operation, and guarantees normal movement even when obstructed, improving its practicality. Note that the mounting plate 2 also has an existing battery box containing a battery that powers the electric telescopic mast 7 and the radar body 3. The battery is a rechargeable battery, which is a standard feature and will not be described in detail here.

[0031] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
