Description

Technical Field

[0001] This utility model relates to the field of track inspection equipment technology, and in particular to fastener and rail light strip inspection equipment based on machine vision detection. Background Technology

[0002] Track inspection refers to the real-time monitoring and data collection of facilities such as tracks, tunnels, and roadbeds in the rail transit system using intelligent detection devices equipped with multiple sensors, and the combination of intelligent analysis to achieve fault early warning and maintenance decision support.

[0003] Track geometry parameter monitoring: Real-time collection of dynamic data such as track geometry parameters (e.g., track flatness, levelness) and axle box acceleration via high-speed integrated inspection trains or track inspection vehicles.

[0004] Structural health inspection: Using technologies such as lidar and infrared thermal imaging, the physical condition and internal damage of track structures (such as rails and tunnel linings) are assessed.

[0005] In summary, the existing track inspection equipment still has the following technical problems: due to its high degree of integration, the current inspection equipment is also becoming increasingly heavy, which makes it inconvenient to move the equipment onto and off the track.

[0036] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0037] Example 1:

[0038] Please refer to Figures 1-4 The fastener and rail light strip inspection equipment based on machine vision inspection includes a rail inspection structure 1, which is used to drive the main body of the equipment to move on the surface of the rail. The upper end of the rail inspection structure 1 is provided with a lifting structure 3 for placing the inspection equipment, and the surface of the rail inspection structure 1 is provided with a fastener connection structure 2 for folding the body structure.

[0039] The rail inspection structure 1 includes a crossbeam 6, with side support beams 7 at both ends of the crossbeam 6, a sensor 5 for detecting the rail on the front of the crossbeam 6, and a visual inspection structure 4 for detecting the rail on the surface of the side support beams 7 on both sides.

[0040] The bottom surface of the crossbeam 6 is symmetrically and fixedly connected to the body support frame 8. The bottom end of the body support frame 8 is provided with a shaft 9, and the surface of the shaft 9 is provided with a steel wheel 10.

[0041] Specifically, the end of the body support frame 8 away from the crossbeam 6 has two gaps, and the connection with the crossbeam 6 forms a triangle. This arrangement of the body support frame 8 can ensure structural stability while reducing the weight of the body itself.

[0042] Specifically, the two support points at the bottom of the machine body support frame 8 are respectively equipped with shafts 9, and the surfaces of the shafts 9 are fixedly connected with steel wheels 10 that are in contact with the track.

[0043] Specifically, the crossbeam 6 and the side support beam 7 are hinged together, and the side of the crossbeam 6 and the side support beam 7 away from the hinge axis are respectively fixedly connected with a locking element 15 and a latch 16.

[0045] Through the above structural design, the upper rail and the rail of the equipment are:

[0046] When mounting the equipment, remove the entire device from the transport equipment and place the steel wheels 10 at the bottom of the two side body support frames 8 on the surface of the two rails in the same direction. After that, flip the side support beams 7 inward so that the end of the crossbeam 6 contacts the end of the side support beam 7. After that, fasten the locking piece 15 and the latch 16. This completes the rapid assembly of the equipment. After opening the vision inspection structure 4 and sensor 5, the track can be inspected.

[0047] When lowering the rail, open the locking piece 15 and the latch 16, flip the side support beam 7 to the rear side of the crossbeam 6 and make it close to the crossbeam 6. After completion, close the vision inspection structure 4 and the sensor 5 to remove the equipment from the rail for loading and transfer.

Push rods 14 are fixedly connected to both ends of the support rod 12. Both ends of the push rods 14 extend to the outer edge of the tray 13.
