Therefore, it should not be construed as a limitation of this patent.

[0030] In the description of this patent, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", "linked", "set" shall be understood in a broad sense. For example, it can be fixedly connected and set, or detachably connected and set, or integrally connected and set. For those of ordinary skill in the art, the specific meanings of the above terms in this patent can be understood according to specific circumstances.

[0031] Referring to Figures 1-3 , a state detection device for the wheels of a rail vehicle, comprising: a mounting plate 1, which is installed on the vehicle body through fixing holes 2 penetrating through its surface and is located above the wheel 15, enabling the entire detection device to be conveniently fixed on the vehicle body with adjustable position to ensure that the detection component can accurately align with the wheel 15; an opening 6, which penetrates through the surface of the mounting plate 1 and internally installs a detection component capable of rotating around an axis. The interior of the opening 6 is configured with an induction component cooperating with the detection component. The design of the opening 6 allows the detection component to freely rotate around the axis inside, which means that regardless of how the rotation direction or speed of the wheel 15 changes, the detection component can contact the wheel 15, thereby realizing real-time and accurate detection of the state of the wheel 15, and forming the detection of the state of the wheel 15 through the cooperation of the induction component and the detection component; one end of the mounting plate 1 is installed with a rotatable and movable sorting component, and through the sorting component, certain cleaning can be performed on the detected abnormal state to reduce the influence received.

[0032] Specifically, referring to Figures 1-3 , the detection component includes: a rotating member II 9, a torsion spring II 10, and a detection portion 5; the rotating member II 9 is connected to the inner side of the opening 6, the torsion spring II 10 is installed on the surface of the rotating member II 9, and the detection portion 5 is installed on the surface of the rotating member II 9. Through this implementation manner, when there are protruding foreign objects mixed on the surface of the wheel 15, due to the rotation of the wheel 15, the foreign objects will gradually contact the detection portion 5 and lift the detection portion 5. The detection portion 5 rotates under the action of the rotating member II 9 and compresses the torsion spring II 10 to move.

[0033] Further, the detection part 5 is configured to be inclined downward in the vertical direction away from one end of the second rotating part 9. Through this design, the inclined detection part 5 can better contact the wheel 15 during the movement process and perform detection, improving the detection effect.

[0034] Specifically, referring to Figures 1-3 , the induction component includes: a bracket 12, a sensor 11, and an elastic member 13; the bracket 12 is installed on one inner side of the opening 6, the sensor 11 is installed at one end of the bracket 12 close to the detection part 5, and the elastic member 13 is installed on the surface of the bracket 12. Through this implementation method, the detection part 5 will gradually contact the sensor 11 during the rotation process, and the sensor 11 can perform a certain elastic movement under the action of the bracket 12 and the elastic member 13 to maintain contact induction with the detection part 5 and have a certain movement space, which is relatively flexible. Further, the sensor 11 can adopt a contact sensor, etc., so that a signal can be generated during the contact process between the detection part 5 and the sensor 11, so as to detect the movement of the detection part 5 and feedback it to the vehicle.

[0035] Specifically, referring to Figures 1-3 , the sorting component includes: a first rotating part 7, a first torsion spring 8, a movable plate 3, and a cleaning part 14; the first rotating part 7 is fixedly connected to one end of the mounting plate 1 close to the wheel 15, the first torsion spring 8 is installed on the surface of the first rotating part 7, the movable plate 3 is installed on the surface of the first rotating part 7, and the cleaning part 14 is constructed at one end of the movable plate 3 away from the first rotating part 7. Further, a connecting member 4 is connected between the movable plate 3 and the detection part 5. Through this design, when the detection part 5 moves, it will pull the movable plate 3 through the connecting member 4, and the movable plate 3 can rotate under the action of the first rotating part 7 and compress the first torsion spring 8, so that the cleaning part 14 gradually contacts the wheel 15 to scrape off foreign objects during the rotation process, which can be synchronized with the detection and processed, avoiding the need to perform corresponding processing only after the vehicle stops, reducing the impact, and being relatively convenient.

[0036] Further, the sorting component is configured to be located in front of the detection component along the traveling direction of the vehicle. Through this design, it is convenient to perform cleaning immediately under the action of the sorting component after detecting the abnormal state of the wheel through the detection component and the induction component, improving the protection effect.

[0037] Working principle: When using the present utility model, first install and fix the mounting plate 1 on the vehicle body through the fixing holes 2. When there are protruding foreign objects mixed on the surface of the wheel 15, due to the rotation of the wheel 15, the foreign object will gradually come into contact with the detection part 5 and push up the detection part 5. Under the action of the rotating member two 9, the detection part 5 rotates and compresses the torsion spring two 10 and contacts the sensor 11. The sensor 11 can perform certain elastic activities under the action of the bracket 12 and the elastic member 13 to maintain contact induction with the detection part 5 and has a certain activity space, which is relatively flexible. When the detection part 5 moves, it will pull the movable plate 3 through the connecting member 4. The movable plate 3 can rotate under the action of the rotating member one 7 and compress the torsion spring one 8, so that the cleaning part 14 gradually comes into contact with the wheel 15 to scrape off the foreign objects during the rotation process, which can be synchronized with the detection and processed, avoiding the need to perform corresponding processing only after the vehicle stops, reducing the impact and being relatively convenient.

[0038] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
