Description

Technical Field

[0001] The utility model relates to the technical field of track detection equipment, in particular to a track side wear dynamic detection device based on machine vision. Background Art

[0002] Tracks generally refer to the routes paved with steel strips for trains, trams, and other vehicles to travel on. In modern industry, especially manufacturing, many manufacturing equipment uses tracks for movement and guidance, and materials are also transported along them. Tracks ensure the stability and accuracy of equipment movement. However, tracks will wear out over time, so regular track inspections are crucial to ensure safe operation.

[0003] In current track inspection technology, inspection cameras can be used to effectively monitor the upper part of the track. However, the side of the track is limited by the shooting angle of the inspection camera, making it difficult to effectively detect wear and tear, which is insufficiently practical. To this end, we propose a dynamic detection device for track side wear based on machine vision. Utility Model Content

[0022] A fixed connection is a connection in which parts or components are fixed without any relative movement. There are two types of connections: detachable and non-detachable.

[0023] (1) A removable connection is a method of fastening components together using screws, splines, wedge pins, etc. This type of connection allows for disassembly during maintenance without damaging the components. However, the connectors used must be of the correct specifications (e.g., length of bolts, keys, wedge pins) and properly tightened.

[0024] (2) Non-detachable connections mainly refer to welding, riveting and tenoning. Since they need to be disassembled by forging, sawing or oxygen cutting when repairing or replacing, spare parts generally cannot be reused. At the same time, when making connections, attention should be paid to the quality of workmanship, technical inspection and remedial measures (such as calibration, polishing, etc.);

[0025] An active connection is a connection in which parts or components are fixed so that they can move relative to each other.

[0035] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure. It should be noted that the embodiments of the present utility model and the features in the embodiments can be combined with each other in the absence of conflict.

[0036] According to the concept of this application, Figures 1 to 4 The following describes an embodiment of a machine vision-based dynamic detection device for track side wear for rail wear detection. Specifically, the machine vision-based dynamic detection device for track side wear is constructed as an integrated structure, comprising three components: an adjustment mechanism 3, a detection mechanism 7, and a positioning seat 1. By changing the angle between the limiting post 71 and the connecting seat 72 and the limiting plate 5, the present invention can achieve the purpose of detecting different positions on the track side wall. The sliding limiting post 71 allows it to move within the arcuate groove 6, and can also adjust the operating height of the camera 73, facilitating detection at positions of different heights. After adjustment, the limiting post 71 can be positioned and fixed under the action of the limiting member 11, thereby ensuring practical use and strong applicability. Furthermore, by rotating the fastener 31 and utilizing the meshing relationship between the internal and external threads, the positioning post 32 can be driven to move within the limiting cylinder 2. The distance between the fixing seat 4 and the limiting cylinder 2 can be adjusted by controlling the extension length of the positioning post 32, thereby facilitating adjustment of the distance between the two detection mechanisms 7, facilitating adaptation to tracks of different widths, and improving the practicality of the device.

[0037] Combine Figure 1-4 As shown, the present invention provides a track side wear dynamic detection device based on machine vision, comprising:

[0038] A positioning seat 1, a limiting cylinder 2 is installed inside the top of the positioning seat 1, and an adjustment mechanism 3 is detachably installed at both ends of the limiting cylinder 2. A fixing seat 4 is installed at the end of the adjustment mechanism 3, and the adjustment mechanism 3 acts on the fixing seat 4;

[0039] The limiting plate 5 is fixedly connected to the bottom end of the fixing base 4. An arc-shaped groove 6 is provided on the side wall of the limiting plate 5, and a detection mechanism 7 is detachably installed in the arc-shaped groove 6;

[0040] The protective frame 8 is fixedly connected to the bottom end of the positioning seat 1, and the inner wall of the protective frame 8 is detachably mounted with a roller 9.

The through hole makes it easy to install the limiting cylinder 2 in the positioning seat 1.

[0042] According to the technical solution of this embodiment, the adjustment mechanism 3 includes a fastener 31 rotatably connected to the two ends of the limiting cylinder 2, and the interior of the fastener 31 is rotatably connected to a positioning column 32, and one end of the positioning column 32 extends into the interior of the limiting cylinder 2, and the diameter of the positioning column 32 is equal to the inner diameter of the limiting cylinder 2.

[0043] Furthermore, the fastener 31 is rotatably connected to the limiting cylinder 2 through a bearing. The inner wall of the fastener 31 is provided with an internal thread, and the outer surface of the positioning column 32 is provided with an external thread that matches the fastener 31. When the fastener 31 is rotated, the meshing relationship between the internal thread and the external thread can be used to drive the positioning column 32 to move inside the limiting cylinder 2, so that the distance between the fixing seat 4 and the limiting cylinder 2 can be adjusted by controlling the extended length of the positioning column 32, thereby facilitating the adjustment of the distance between the two detection mechanisms 7, facilitating the adaptation to tracks of different widths, and improving the practicality of the device. After the adjustment is completed, tightening the fastener 31 can achieve the installation stability of the positioning column 32, that is, it will not move during use, and the actual detection effect can be guaranteed.

[0044] Furthermore, a mounting hole 10 that is compatible with the positioning column 32 is opened inside the fixing seat 4, and the end of the positioning column 32 away from the limiting cylinder 2 is inserted into the mounting hole 10. When the staff adjusts the extension length of the positioning column 32, they will rotate the fastener 31 with one hand and hold the fixing seat 4 with the other hand to limit the positioning rod and prevent the positioning rod from rotating with the fastener 31. It should be noted that after the positioning column 32 is inserted into the mounting hole 10, the positioning column 32 and the fixing seat 4 are relatively fixed.

[0045] Furthermore, there are four limit plates 5 , and two limit plates 5 are used together as a group. The limit plates 5 are mainly used to provide support for the detection mechanism 7 .

[0046] According to the technical solution of this embodiment, the detection mechanism 7 includes a limiting column 71 inserted into the arc groove 6, and both ends of the limiting column 71 extend out of the arc groove 6. A connecting seat 72 is installed on the outer surface of the limiting column 71, and a camera 73 is installed at the bottom of the connecting seat 72.

[0049] According to the technical solution of this embodiment, through holes are opened inside on both sides of the protective frame 8, and pin shafts 12 are installed in the through holes. Pin holes matching the pin shafts 12 are opened on the side walls at both ends of the roller 9, and the roller 9 and the pin shaft 12 are coaxially arranged. Under the action of the protective frame 8, the support purpose of the positioning seat 1 can be achieved, and the protection purpose of the roller 9 can also be achieved. Under the action of the positioning column 32, the connection stability between the protective frame 8 and the roller 9 can be guaranteed, and the roller 9 is tangent to the track, that is, the overall movement purpose of the device can be achieved, and by replacing different rollers 9, the use requirements of different tracks can be met, and it has strong applicability.

[0050] Specifically, when track inspection is required, the roller 9 is first installed on the protective frame 8 through the pin 12, and then the fastener 31 is rotated, and the meshing relationship between the internal thread and the external thread is used to drive the positioning column 32 to move inside the limiting cylinder 2, so that the distance between the fixing seat 4 and the limiting cylinder 2 can be adjusted by controlling the extended length of the positioning column 32, thereby facilitating the adjustment of the distance between the two detection mechanisms 7 and adapting to tracks of different widths. When the adjustment is completed, the fastener 31 is tightened to ensure the installation stability of the positioning column 32, and then the limiting piece 11 is loosened to adjust the limiting column 71 and the connecting seat 72. The locking member 71 is unlocked, and then the deflection angle of the connecting seat 72 and the camera 73 is turned according to the detection requirements, so as to realize the detection purpose of different positions of the track side wall. Then the limiting column 71 is slid to move it in the arc groove 6, and the use height of the camera 73 can be adjusted to facilitate the detection of positions at different heights.

Then, by moving the roller 9 on the track, the camera 73 can be driven to move to detect the wear of the track side wall.
