Description

Technical Field

[0001] This utility model relates to a road guardrail inspection device, belonging to the field of guardrail inspection technology. Background Technology

[0002] Currently, road guardrails require regular inspection to ensure traffic safety and prevent potential risks. Inspection mainly covers rust, cracks, deformation, and missing parts. The primary inspection method is manual patrol, which, while flexible and intuitive, also has significant limitations.

[0003] Manual inspections require walking or driving at low speeds to check sections of road, especially in long distances such as mountainous areas and highways. This results in long inspection cycles, low efficiency, and difficulty in timely detection of problems. The rate of missed inspections is high, and human eyes are prone to fatigue, potentially overlooking rust, minor cracks, or missing small parts (such as bolts) in complex environments. Manual inspections rely heavily on the skills and experience of the inspectors, making it difficult to accurately measure deformation, and are inherently subjective and lacking in precision.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] This invention addresses the shortcomings of the prior art by providing a road guardrail detection device that can move along the length of the road guardrail. During the movement, it captures real-time image information of the top and sides of the road guardrail. By processing and analyzing the image information, it achieves real-time detection of the guardrail, significantly improving detection efficiency and ensuring detection accuracy.

[0006] To solve the above technical problems, the present invention adopts the following technical solution:

[0007] The road guardrail inspection equipment includes a crossbeam. An L-shaped swing arm is rotatably connected to one end of the crossbeam. An inverted T-shaped support is fixed to the bottom of the L-shaped swing arm. A first image capture module facing downward is fixedly installed at the bottom of the inverted T-shaped support. Arc-shaped swing arms are hinged to the left and right ends of the inverted T-shaped support respectively. The tops of the two arc-shaped swing arms are connected by an electric push rod. A detection arm is connected to the bottom of each arc-shaped swing arm. A second image capture module is fixedly installed below the end of the detection arm.

[0008] Furthermore, the crossbeam is fixed to the front of the moving vehicle body by two symmetrically arranged connectors, and the crossbeam is arranged in a horizontal direction.

[0009] Furthermore, the bottom end of the L-shaped swing arm is connected to the crossbeam via a slewing bearing, and a stepper motor that drives the L-shaped swing arm to move along the slewing bearing is installed at the bottom of the crossbeam.

[0010] Furthermore, the middle part of the arc-shaped swing arm is hinged to the inverted T-shaped support, and the arc-shaped opening of the arc-shaped swing arm is set to face the side away from the inverted T-shaped support.

[0011] Furthermore, the bottom end of the arc-shaped swing arm is connected to the end of the detection arm via a flange.

[0012] Furthermore, the electric push rod is arranged in a horizontal direction, and the head and tail of the electric push rod are respectively hinged to the top of the arc-shaped swing arm.

[0013] Furthermore, the first image capture module and the second image capture module are cameras.

[0014] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0015] The moving vehicle body drives the inverted T-shaped support and the detection arm to move along the length of the road guardrail. The first image capture module at the bottom of the inverted T-shaped support and the second image capture module on the detection arm can capture image information of the top and sides of the road guardrail in real time. By processing and analyzing the image information, real-time detection of the guardrail can be achieved, significantly improving detection efficiency and ensuring detection accuracy.

Detailed Implementation

[0021] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0022] like Figures 1-3As shown in the figure, this utility model provides a road guardrail detection device, including a crossbeam 1. An L-shaped swing arm 3 is rotatably connected to one end of the crossbeam 1. An inverted T-shaped support 6 is fixedly connected to the bottom of the L-shaped swing arm 3. A first image capture module 7 facing downward is fixedly installed at the bottom of the inverted T-shaped support 6. Arc-shaped swing arms 8 are respectively hinged to the left and right ends of the inverted T-shaped support 6. The tops of the two arc-shaped swing arms 8 are connected by an electric push rod 12. A detection arm 9 is connected to the bottom of each arc-shaped swing arm 8. A second image capture module 11 is fixedly installed below the end of the detection arm 9.

[0023] The crossbeam 1 is fixed to the front of the moving vehicle body 13 by two symmetrically arranged connectors 2, and the crossbeam 1 is arranged in the horizontal direction.

[0024] The bottom end of the L-shaped swing arm 3 is connected to the crossbeam 1 via a slewing bearing 4. A stepper motor 5 is installed at the bottom of the crossbeam 1 to drive the L-shaped swing arm 3 to move along the slewing bearing 4. The stepper motor 5 can drive the L-shaped swing arm 3 to rotate 180 degrees along the slewing bearing 4.

[0025] The first image capture module 7 is used to capture the top image information of the road guardrail 14, and the second image capture module 11 is used to capture the side image information of the road guardrail 14.

[0026] The middle part of the arc-shaped swing arm 8 is hinged to the inverted T-shaped support 6, and the arc-shaped opening of the arc-shaped swing arm 8 is set towards the side away from the inverted T-shaped support 6.

[0027] The bottom end of the arc-shaped swing arm 8 is connected to the end of the detection arm 9 via a flange 10. The flange 10 connection facilitates the assembly and disassembly of the detection arm 9. The detection arm 9 is available in various lengths to accommodate road guardrails 14 of different heights.

[0028] The electric push rod 12 is arranged horizontally, and its head and tail are respectively hinged to the top of the arc-shaped swing arm 8. The electric push rod 12 provides power for the swing of the detection arm 9.

[0029] The first image capture module 7 and the second image capture module 11 of this utility model are cameras.

[0030] The specific working principle of this utility model is as follows:

[0031] During the inspection, the stepper motor 5 drives the L-shaped swing arm 3 to rotate 180 degrees along the slewing bearing 4, rotating the L-shaped swing arm 3 to the side of the moving vehicle 13, so that the inverted T-shaped support 6 is positioned above the road guardrail 14. Then, the electric push rod 12 extends, causing the detection arm 9 to swing to both sides of the road guardrail 14. The moving vehicle 13 drives the inverted T-shaped support 6 and the detection arm 9 to move along the length of the road guardrail 14. The first image capture module 7 and the second image capture module 11 capture the image information of the top and sides of the road guardrail 14 in real time. By processing and analyzing the image information, the real-time detection of the guardrail is achieved.
