Description

Technical Field

[0001] This invention belongs to the technical field of bridge inspection, and specifically discloses an inspection device for roads and bridges. Background Technology

[0002] With the rapid development of transportation infrastructure, bridges, as key nodes, have received significant attention for their safety and durability. Crash barriers (also known as crash walls or guardrails) are crucial protective structures for bridges, primarily responsible for buffering and absorbing energy during accidental vehicle collisions. They are also subject to long-term exposure to complex environments (such as temperature and humidity changes, salt spray corrosion, freeze-thaw cycles, and ultraviolet radiation). However, existing crash barriers commonly suffer from serious problems of surface concrete powdering and spalling. Specifically, the concrete surface experiences reduced strength due to carbonation, salt penetration, or freeze-thaw cycles, resulting in powdering, sanding, and large-scale spalling. Powdering and spalling reduce the surface roughness of the crash barrier, weakening its impact resistance. Simultaneously, exposed rebar and loose concrete can cause secondary damage to vehicles or ships. Therefore, it is necessary to inspect the crash barriers of bridges. Currently used bridge inspection methods, such as manual visual inspection and simple tapping tests, require manual marking of defect locations afterward for subsequent repairs. This method is labor-intensive, and the frequent marking makes it difficult to accurately determine the specific area of ​​powdering, leading to resource waste. Summary of the Invention

[0003] The purpose of this invention is to solve the problems existing in the background art, and to propose a road and bridge inspection device, including a traveling vehicle. A reserve battery is provided on the upper surface of the traveling vehicle near the middle. Anti-slip support mechanisms are symmetrically provided on both sides of the upper surface of the traveling vehicle. Warning bars are vertically provided on the upper surface of each of the anti-slip support mechanisms. Support plates are provided on the outer sides of each of the four warning bars. A platform is provided on the end of the four support plates away from the warning bars. A mounting box is provided on one side of the platform. A sliding block is connected to the inner side of the mounting box through a lifting mechanism. A protective shell is provided on the outer side of the sliding block. A line scan camera is provided inside the protective shell. Marking and grinding mechanisms are provided on both sides of the outer wall of the protective shell.

[0004] Preferably, the anti-slip support mechanism includes a hydraulic jack installed on the upper surface of the vehicle, an anti-slip plate fixedly installed at the telescopic end of the hydraulic jack, the bottom of the anti-slip plate being supported by the ground, and one end of the warning bar being connected to the upper surface of the hydraulic jack.

[0005] Preferably, the lifting mechanism includes a first lead screw rotatably installed inside the mounting box, the upper end of the first lead screw passing through the outside of the mounting box and connected to a first motor, the first motor being fixedly installed above the mounting box, the slide block threaded through the outside of the first lead screw, and the two side edges of the slide block slidingly fitting against the inner wall of the mounting box.

[0006] Preferably, the marking and polishing mechanism includes a fixed frame fixedly mounted on one side of the outer wall of the protective shell. One end of the fixed frame is provided with a support rod. A second lead screw is rotatably mounted inside the lower part of the support rod. One end of the second lead screw passes through the outside of the support rod and is connected to a second motor. The second motor is fixedly mounted on the outside of one end of the support rod. A slider is provided on both the outside of the second lead screw and the support rod. The slider is threadedly connected to the second lead screw and slidably connected to the support rod. A pressing mechanism is provided inside the upper part of the slider, and a support mechanism is provided on the lower surface of the slider.

[0007] Preferably, the pressing mechanism includes a sliding frame slidably disposed above the inside of the slider, a cylinder is disposed on the outer wall of the slider near the fixed frame, the telescopic end of the cylinder is connected to the inner surface of the slider, and an electrical control component is disposed on the outer side of the sliding frame.

[0008] Preferably, the support mechanism includes a support column fixedly disposed on the lower surface of the slider, a mounting buckle fixedly disposed on the outer side of the support column, connecting rods rotatably connected to both sides of the outer wall of the mounting buckle through a set rotating shaft, an L-shaped rod disposed on the lower surface of the mounting buckle, and guide rods disposed on the upper surfaces of the two connecting rods, the upper ends of the guide rods being spherical, and the lower edge of the moving frame near the guide rods being curved.

[0009] Preferably, a third motor is provided between the two connecting rods, a grinding disc is provided at the output end of the third motor, a ring is fitted on the outside of the third motor, a contraction spring is provided at the lower end of the ring, and the lower end of the contraction spring is connected to the inner surface of the L-shaped rod.

[0010] Preferably, the electrical control assembly includes a grounding block fixedly disposed on the outside of the moving frame, an electromagnetic rod linearly connected to the outer surface of the grounding block, and an electrical control switch disposed on the outer surface of the grounding block and above the electromagnetic rod.

[0011] Preferably, a transparent film window is slidably installed at the front end of the inner side of the protective shell, and a cleaning rod is slidably installed at the outer edge of the front end of the protective shell. One side of the cleaning rod is slidably attached to the outer surface of the transparent film window, and a bidirectional permanent magnet column is provided on the side of the cleaning rod away from the transparent film window.

[0012] Compared with the prior art, the present invention has the following beneficial effects: With the installation box, first lead screw, first motor, slide block, protective shell, and line scan camera, the line scan camera can be driven up and down repeatedly during the movement of the vehicle, allowing it to gradually scan the outer surface of the bridge crash barrier. This is suitable for rapid frame-by-frame inspection of bridges during routine inspections.

[0013] By setting marking and grinding mechanisms on both sides of the outer shell, after detecting areas of powdering and flaking, the second motor drives the second lead screw to rotate, causing the front slider to move towards the bridge crash barrier. The third motor drives the grinding disc to rotate, causing the grinding disc to grind the powdered area and treat it. This not only cleans up the powdered concrete but also makes the repair location clear at a glance, greatly improving the efficiency of subsequent repair work and reducing the difficulty and time cost of repair work.

[0014] The shifting frame, in conjunction with the cylinder, connecting rod, ring, retraction spring, and guide rod, can be flexibly adjusted according to the structure of the bridge crash barrier. When encountering an area with an inclined surface above the crash barrier, the cylinder pushes the shifting frame, causing the curved surface of the lower edge of the shifting frame to press against the spherical mechanism of the guide rod, thereby adjusting the angle of the connecting rod so that the grinding disc can closely fit the inclined surface for grinding operations. It can efficiently handle both flat and inclined powdery areas.

[0015] When the entire structure of the moving frame and slide is moved to one side of the protective shell by the set electronic control switch, the electronic control switch is turned on, so that the grounding block is electrically connected to the electromagnetic rod. This creates a driving relationship between the same pole and opposite pole of the bidirectional permanent magnet column at the cleaning rod inside the front of the protective shell. This causes the cleaning rod to be operated by the magnetic field and automatically slide at the front of the transparent film window, prompting the cleaning rod to wipe the transparent film window. This solves the problem of dust adhering to the transparent film window during the polishing process, which reduces the clarity of the transparent film window and affects the normal use of the line scan camera.

Detailed Implementation

[0018] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0020] like Figures 1-7 The road and bridge inspection equipment shown includes a traveling vehicle 1. A reserve battery 13 is installed on the upper surface of the traveling vehicle 1 near the middle. Anti-slip support mechanisms are symmetrically arranged on both sides of the upper surface of the traveling vehicle 1. Warning bars 3 are vertically arranged on the upper surface of each of the four anti-slip support mechanisms. Support plates 12 are arranged on the outer side of each of the four warning bars 3. A platform 2 is arranged on the end of the four support plates 12 away from the warning bars 3. A mounting box 11 is arranged on one side inside the platform 2. A sliding seat 14 is connected to the inner side of the mounting box 11 through a lifting mechanism. A protective shell 9 is arranged on the outer side of the sliding seat 14. A line scan camera 33 is arranged inside the protective shell 9. Marking and grinding mechanisms are arranged on both sides of the outer wall of the protective shell 9.

[0021] The anti-slip support mechanism includes a hydraulic top 4 installed on the upper surface of the traveling vehicle 1. An anti-slip plate 6 is fixedly installed at the telescopic end of the hydraulic top 4. The bottom of the anti-slip plate 6 is supported by the ground. One end of the warning rod 3 is connected to the upper surface of the hydraulic top 4. During the inspection process, when it is necessary to stabilize the equipment, the hydraulic top 4 extends to make the anti-slip plate 6 tightly support the ground, increase the stability of the equipment, and prevent the traveling vehicle 1 from sliding during the inspection. The warning rod 3 is installed on the upper surface of the hydraulic top 4 to serve as a warning, reminding the surrounding personnel to pay attention to the operation of the equipment and ensuring safety. The traveling vehicle 1 is a common electric traveling mechanism, which consists of a platform, an electric traveling drive motor, wheel sets, a reducer, and other structures. In actual operation, reflective stickers can be affixed to the exterior of the warning pole 3 to enhance safety during inspection.

[0022] The lifting mechanism includes a first lead screw 5 rotatably installed inside the mounting box 11. The upper end of the first lead screw 5 passes through the outside of the mounting box 11 and is connected to a first motor 10. The first motor 10 is fixedly installed above the mounting box 11. A slide block 14 is threaded through the outside of the first lead screw 5. The two sides of the slide block 14 slide against the inner wall of the mounting box 11. When the first motor 10 is started, it drives the first lead screw 5 to rotate. Under the action of the thread, the slide block 14 moves up and down along the first lead screw 5, thereby adjusting the height of the protective shell 9 and the line scan camera 33, and realizing the scanning detection of different height positions of the bridge anti-collision wall.

[0023] The marking and grinding mechanism includes a fixed frame 15 fixedly installed on one side of the outer wall of the protective shell 9. A support rod 8 is provided at one end of the fixed frame 15. A second lead screw 16 is rotatably installed inside the lower part of the support rod 8. One end of the second lead screw 16 passes through the outside of the support rod 8 and is connected to a second motor 17. The second motor 17 is fixedly installed on the outside of one end of the support rod 8. A slider 19 is provided on both the outside of the second lead screw 16 and the support rod 8. The slider 19 is threadedly connected to the second lead screw 16 and slidably connected to the support rod 8. A pressing mechanism is provided on the upper part of the slider 19 and a support mechanism is provided on the lower surface of the slider 19. After the second motor 17 is started, the second lead screw 16 rotates, driving the slider 19 to move on the support rod 8, so that the marking and grinding mechanism moves closer to or away from the bridge crash barrier. A pressing mechanism is set on the upper part of the slider 19, and a support mechanism is set on the lower surface, which work together to complete the grinding operation.

[0024] The pressing mechanism includes a sliding frame 18 that is slidably disposed above the inside of the slider 19. A cylinder 36 is disposed on the outer wall of the slider 19 near the fixed frame 15. The telescopic end of the cylinder 36 is connected to the inner surface of the slider 19. An electrical control component is disposed on the outer side of the sliding frame 18. The support mechanism includes a support column 27 that is fixedly disposed on the lower surface of the slider 19. A mounting buckle 28 is fixedly disposed on the outer side of the support column 27. Connecting rods 22 are rotatably connected to both sides of the outer wall of the mounting buckle 28 through a rotating shaft 29. An L-shaped rod 23 is disposed on the lower surface of the mounting buckle 28. Guide rods 30 are disposed on the upper surface of both connecting rods 22. The upper end of the guide rod 30 is spherical. The lower edge of the sliding frame 18 near the guide rod 30 is curved. A third motor 20 is provided between the two connecting rods 22. A grinding disc 7 is provided at the output end of the third motor 20. A ring 31 is fitted on the outside of the third motor 20. A contraction spring 21 is provided at the lower end of the ring 31. The lower end of the contraction spring 21 is connected to the inner surface of the L-shaped rod 23. When encountering an inclined surface, when it is necessary to adjust the angle of the grinding disc 7, the cylinder 36 drives the moving frame 18 to move. The cylinder 36 can drive the moving frame 18 to move towards the front end of the slider 19 until the curved surface of the lower edge of the front end of the moving frame 18 presses against the ball mechanism of the guide rod 30, and presses against the connecting rod 22 downwards, further adjusting the angle of the connecting rod 22 to ensure that the grinding disc 7 continues to fit against the inclined surface and efficiently grinds the powdered area of ​​the inclined surface. By compressing the spring 21 and rotating the connecting rod 22, the grinding disc 7 adapts to the inclined structure, thus achieving precise control over the angle of the grinding disc 7.

[0025] The electrical control assembly includes a grounding block 24 fixedly installed on the outside of the transfer frame 18, an electromagnetic rod 26 linearly connected to the outer surface of the grounding block 24, an electrical control switch 25 installed on the outer surface of the grounding block 24 and above the electromagnetic rod 26, a transparent film window 32 slidably installed inside the front end of the protective shell 9, a cleaning rod 35 slidably installed on the outer edge of the front end of the protective shell 9, one side of the cleaning rod 35 slidably fits against the outer surface of the transparent film window 32, and a bidirectional permanent magnet column 34 is provided on the side of the cleaning rod 35 away from the transparent film window 32; When the moving frame 18 moves to the protective shell 9, the electric control switch 25 is turned on, the power block 24 and the electromagnetic rod 26 are energized, and a magnetic field is generated. This magnetic field interacts with the bidirectional permanent magnet column 34 at the cleaning rod 35, realizing the automatic sliding cleaning of the cleaning rod 35, thereby ensuring the clear field of view of the line scan camera 33. It should be noted that after the electromagnetic rod 26 is energized, the polarity of it switches with that of the bidirectional permanent magnet column 34 to achieve the reciprocating motion of the cleaning rod 35. The wiping surface of the cleaning rod 35 can be made of materials such as textile cotton cloth.

[0026] The transparent film window 32 can be placed at the front end of the line scan camera 33 to isolate dust; The line scan camera 33 can capture and photograph images by connecting to an external computer (mobile client), which is a common component of existing technology and will not be described in detail here. The storage battery 13 on the vehicle 1 can supply power to the electrical components on the device.

[0027] Working principle: When in use, the traveling vehicle 1 moves on the bridge, and the mounting box 11 and the protective shell 9 are set parallel to one side of the bridge crash barrier. The first motor 10 starts and drives the first lead screw 5 to rotate, so that the slide block 14, which is threaded with the first lead screw 5, can move up and down inside the mounting box 11. The line scan camera 33 scans the outer surface of the bridge crash barrier frame by frame during the movement of the traveling vehicle 1. When the linear scan camera 33 scans the powdery and peeling area, the traveling vehicle 1 stops moving, the hydraulic jack 4 drives the anti-slip plate 6 to stick to the ground, stabilizes the traveling vehicle 1, adjusts the height of the current protective shell 9 so that the support pole 8 is close to the powdery area, the second motor 17 starts to drive the second lead screw 16 to rotate, and drives the slider 19 to move to the front end of the bridge crash barrier so that the grinding disc 7 contacts the powdery wall surface. Then the third motor 20 starts to drive the grinding disc 7 to rotate, grind the powdery wall skin, peel off the wall skin, complete the pretreatment of the powdery area, and mark the repair position. When grinding the area above the bridge crash barrier that is set on a slope, the lower edge of the grinding disc 7 abuts against the slope wall. At this time, the connecting rod 22 rotates downward as the grinding disc 7 is in contact with it, and the compression spring 21 is compressed and tilted, so that the outer surface of the grinding disc 7 is in contact with the slope. At this time, the cylinder 36 can drive the moving frame 18 to move towards the front end of the slider 19 until the curved surface of the lower edge of the front end of the moving frame 18 presses against the ball mechanism of the guide rod 30, presses the connecting rod 22 downward, and further adjusts the angle of the connecting rod 22 to ensure that the grinding disc 7 continues to be in contact with the slope, efficiently grinding the powdery area of ​​the slope and peeling off the uneven and bulging wall. During the wall plastering process, to prevent dust from adhering to the surface of the transparent film window 32 at the front end of the protective shell 9, when the slider 19 and the moving bracket 18 move to the rear end, and the electromagnetic rod 26 approaches the bidirectional permanent magnet column 34, the electronic control switch 25 is activated, causing the grounding block 24 and the electromagnetic rod 26 to be energized to generate a repulsive magnetic field, which drives the nearby cleaning rod 35 to move to the other side. Thus, the cleaning rod 35 can clean the dust on the outer surface of the transparent film window 32. When the cleaning rod 35 slides to the other side, the electromagnetic rod 26 on the other side is energized. This cycle is repeated to achieve automatic cleaning of the transparent film window 32 and ensure a clear field of view for the line scan camera 33.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention.
