Description

Technical Field

[0001] This utility model belongs to the technical field of inspection devices, specifically relating to a track inspection device installed on a track inspection vehicle. Background Technology

[0002] Rail fasteners, sleepers, and track bed are crucial components of subway infrastructure, and defects in these facilities can impact the safe operation of the subway. These components may malfunction, become damaged, or pose safety hazards during long-term operation. Regular inspections are a critical step in ensuring the normal operation of the subway, enabling timely detection of problems and the implementation of appropriate repair and protective measures to prevent accidents.

[0003] Traditional subway inspections primarily rely on manual methods, with inspectors checking the appearance and operational status of equipment along fixed routes. This approach has several drawbacks. Firstly, manual inspections are inefficient, requiring significant manpower and time, especially for large-scale subway networks where frequent, comprehensive inspections are difficult to achieve. Secondly, human visual inspections are susceptible to subjective factors such as fatigue and lack of concentration, potentially leading to missed or false detections. Furthermore, some minor faults or hidden hazards concealed in complex environments may be difficult to detect manually.

[0004] Current track inspection generally uses a three-camera solution, which takes pictures of the left, middle and right parts of the track respectively and then stitches them together to form an image of the entire track. The large number of cameras results in relatively high costs and needs to be optimized. Utility Model Content

[0005] In view of the problems mentioned above in the background art, the purpose of this utility model is to provide a track inspection device installed on a track inspection vehicle.

[0006] To achieve the above technical objectives, the technical solution adopted by this utility model is as follows:

[0007] A track inspection device installed on a track inspection vehicle includes a left connecting plate and a right connecting plate. A support bracket is connected between the left connecting plate and the right connecting plate. The support bracket is evenly provided with a plurality of mounting holes. A left acquisition unit, a right acquisition unit, and a power supply box are installed on the support bracket through the mounting holes. An aviation plug is installed at the output end of the power supply box. The other end of the aviation plug is connected to the left acquisition unit and the right acquisition unit through a cable.

[0008] The left acquisition unit and the right acquisition unit have the same specifications, model and structure. The left acquisition unit includes a mounting plate, and mounting brackets are installed on both sides of the mounting plate. A track surface camera is installed on one side of the mounting bracket, and a track camera is installed on the other side of the mounting bracket.

[0009] Furthermore, a central connecting plate is installed in the middle of the support bracket. This design strengthens the installation strength of the support bracket and thus enhances the stability of the components installed on the support bracket.

[0010] Furthermore, the support bracket is equipped with a slider through the mounting hole, and the left acquisition unit and the right acquisition unit are each mounted on the slider at the corresponding position. This design facilitates the adjustment and change of the installation position of the left acquisition unit and the right acquisition unit.

[0011] Furthermore, the mounting plate is equipped with a protective shell on its outer side. This design prevents impurities from affecting the operation of internal components and blocks external objects from impacting the internal components.

[0012] Furthermore, both the left and right acquisition units are equipped with LED light sources, filters, and camera trigger lines. This design allows the LED light sources to provide illumination, while the filters protect the camera lens from moisture, dirt, and scratches. The effect of the filters is particularly noticeable when shooting in humid, dusty, or muddy environments. By reducing glare and reflection, enhancing color, and changing the angle and color of incident light, the filters can control the contrast of the image, i.e., the contrast between light and dark, making the subject clearer and brighter. Simultaneously, it enriches tonal gradations and color expression capabilities, improving image clarity. Furthermore, the filters can change the color temperature, making the colors in the image more natural and realistic. The camera trigger line enables control of the camera's operation via external signals; that is, when the track inspection vehicle begins to move, the left and right acquisition units start operating.

[0013] The beneficial effects of using this utility model are as follows:

[0014] This invention enables fully automated inspection of tracks and rail surfaces, saving labor costs.

[0015] By adopting the structural design of this utility model, with the cooperation of the left and right acquisition units and a lens with a focal length of 8mm, the installation height is 750mm. The field of view of a single acquisition unit can cover up to 2600mm. After removing the overlapping part of the captured image, the field of view of the two camera acquisition modules reaches 3520mm, requiring fewer cameras while covering a wider shooting range.

[0024] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figures 1-4 As shown, a track inspection device installed on a track inspection vehicle according to the present invention includes a left connecting plate 1 and a right connecting plate 2. A support bracket 3 is connected between the left connecting plate 1 and the right connecting plate 2. The support bracket 3 is evenly provided with a plurality of mounting holes 4. A left acquisition unit 5, a right acquisition unit 6 and a power supply box 7 are installed on the support bracket 3 through the mounting holes 4. An aviation plug 8 is installed at the output end of the power supply box 7. The other end of the aviation plug 8 is connected to the left acquisition unit 5 and the right acquisition unit 6 through a cable.

[0026] The left acquisition unit 5 and the right acquisition unit 6 have the same specifications, model and structure. The left acquisition unit 5 includes a mounting plate 51. Mounting brackets 52 are installed on both sides of the mounting plate 51. A track camera 53 is installed on one side of the mounting bracket 52, and a track camera is installed on the other side of the mounting bracket 52.

[0027] In this implementation case, when using a track inspection device installed on a track inspection vehicle, the support bracket 3 is installed at the bottom of the track inspection vehicle through the left connecting plate 1 and the right connecting plate 2. Then, data can be collected from the track and track surface through the left acquisition unit 5 and the right acquisition unit 6. The power supply box 7 is used to supply power to the left acquisition unit 5 and the right acquisition unit 6.

[0028] When the track inspection vehicle is running, the track surface camera 53 and the track camera 54 on both sides of the mounting bracket 52 operate. The track surface camera 53 collects data from the track surface, and the track camera 54 collects data from the track. To further explain, the camera is a 4K high-speed linear array camera with an 8mm focal length lens and an installation height of 750mm. The maximum field of view of a single camera can cover 2600mm. After removing the overlapping parts of the captured images, the field of view of the two camera acquisition modules reaches 3520mm. Compared with the existing technology that uses three cameras, fewer cameras are used, while the shooting range is wider.

[0029] Preferably, a central connecting plate is installed in the middle of the support bracket 3. This design strengthens the installation strength of the support bracket 3 and enhances the stability of the components installed on the support bracket 3. In fact, the fixing method of the support bracket 3 can also be considered according to the specific situation.

[0030] The preferred support bracket 3 is equipped with a slider 9 through the mounting hole 4. The left acquisition unit 5 and the right acquisition unit 6 are each mounted on the slider 9 at the corresponding position. This design facilitates the adjustment and change of the installation position of the left acquisition unit 5 and the right acquisition unit 6. In fact, an installation structure that facilitates the adjustment of the installation position can also be considered according to the specific situation.

[0031] It is preferred that a protective shell 55 is installed on the outside of the mounting plate 51. This design prevents impurities from affecting the operation of internal components and blocks foreign objects from hitting internal components. In fact, protective measures and the material selection of the protective shell 54 can also be considered according to specific circumstances.

[0032] Ideally, both the left acquisition unit 5 and the right acquisition unit 6 are equipped with LED light sources, filters, and camera trigger lines. This design allows the LED light sources to provide illumination, while the filters protect the camera lens from moisture, dirt, and scratches. The effect of the filters is particularly noticeable when shooting in humid, dusty, or muddy environments. By reducing glare and reflection, enhancing color, and changing the angle and color of incident light, the filters can control the contrast of the image, making the subject clearer and brighter. Simultaneously, they enrich tonal gradations and color expression, improving image clarity. Furthermore, the filters can change the color temperature, making the colors in the image more natural and realistic. The camera trigger line enables control of the camera's operation via external signals; that is, when the track inspection vehicle begins its movement, the left acquisition unit 5 and the right acquisition unit 6 start operating. In practice, the choice of accessories for the left acquisition unit 5 and the right acquisition unit 6 can also be considered depending on the specific circumstances.

[0033] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
