Description

Technical Field

[0001] The present invention relates to the field of measurement, and more specifically to an experimental turning rail capable of realizing multiple working conditions and a control method thereof. Background Art

[0002] Due to the rapid development of rail transit technology, the driving tracks on multiple terrains will be laid with different inclinations during the construction process. In the actual track maintenance process, different inclinations and track spacings will be generated due to track laying, which will cause different measurement angles and measurement problems. At the same time, when the track spacing of the train is different, the wheel wear and track wear parts will also change, so there will be different methods for wheel maintenance and track maintenance. At the same time, when passing through the switch, the balance between the tracks will also change. At the same time, the wheels will wear differently on both sides, and after a period of time, there will be certain road safety hazards.

[0003] In traditional testing, the wear condition of wheels and tracks can only be inspected after the vehicle has run for a cycle; therefore, the wear condition during the operation of the vehicle cannot be controlled and detected.

[0004] Chinese patent publication number CN110346101A discloses a vibration performance equivalent simulation experimental device and method for a high-speed railway wheel set under running state, comprising: a power mechanism (1), a support mechanism (2), and a wheel rail (3); the power mechanism (1) is installed above the wheel rail (3) through the support mechanism (2); the support mechanism (2) is located on both sides of the power mechanism (3); the wheel rail (3) is fixed on a specific ground and is located directly below the power mechanism (1); wherein the surface of the wheel rail (3) is provided with different vibration-inducing block groups, the power mechanism (1) drives the high-speed railway wheel set to rotate, and the high-speed railway wheel set and the surface of the wheel rail (3) are externally cut. The invention has a simple structure and is easy to operate. It can simulate the coupling effect between the wheel and rail of the high-speed railway wheel set during actual operation and the vibration characteristics caused by different track height unevenness through the contact effect between the wheel rail and the high-speed railway wheel set, effectively saving experimental costs and improving experimental efficiency. However, it does not simulate the spacing between the tracks, the inclination angle between the tracks, or the inclination angle of the tracks relative to the ground, and cannot simulate the wear condition of the vehicle during operation.

[0037] The working process of embodiment 1 of the present invention is as follows: when the tilting of the flipping rail relative to the ground is to be achieved, the hand wheel 301 is rotated, the moving shaft 304 rotates, the first gear 303 is meshed with the second gear 305, thereby driving the flipping screw 302 to rotate, the flipping screw 302 drives the first screw 307 to rotate through the first chain 306, and the moving shaft 304 drives the second screw 309 to rotate through the second chain 308. The rotation of the flipping screw 302, the first screw 307 of the moving shaft 304 and the second screw 309 causes the flipping base plate 2 to be subjected to a force in the vertical direction relative to the horizontal plane on the side close to the first rail 6, and the side of the flipping body close to the second rail 7 is rotatably connected to the support frame 1, so that the flipping base plate 2 is tilted relative to the horizontal plane on the side close to the first rail 6; wherein, the direction of the force in the vertical direction relative to the horizontal plane on the side close to the first rail 6 on the flipping base plate 2 is determined according to the direction of rotating the hand wheel 301.

[0038] When the distance between the first rail 6 and the second rail 7 is to be adjusted, the first handle 405 is rotated, and the translation screw connected to the first universal coupling 406 moves axially relative to the first sleeve 407, thereby exerting a thrust or a pull on the rectangular slide 412, so that the rectangular slide 412 slides in the slide rail. The rectangular slide 412 is connected to the flange mounting plate 413 through the rotary mounting plate 411 and the pad 414, and the flange mounting plate 413 is fixedly connected to the bottom surfaces of the first cross bar 401 and the second cross bar 402, so that the sliding of the rectangular slide 412 drives the first cross bar 401 and the second cross bar 402 to move. The first cross bar 401 and the second cross bar 402 are fixedly connected to the first rail mounting plate 5 above. 06. The first rail mounting plate 506 is fixedly connected to the first rail 6, so that the movement of the first cross bar 401 and the second cross bar 402 drives the movement of the first rail 6, and the second handle 501 is rotated at the same time, so that the second handle 501 and the first handle 405 rotate the same number of circles, so that the axial movement distance of the second universal coupling 502 and the tilting screw 505 connected to the second handle 501 is the same as the axial movement distance of the translation screw, so that the first rail 6 moves parallel to the second rail 7; wherein, the rectangular slide 412 is subjected to thrust or tension, depending on the direction of rotating the first handle 405, and the direction of axial movement of the tilting screw 505 is determined according to the rotation direction of the second handle 501.

[0039] When the first rail 6 is to be tilted relative to the second rail 7 on the same plane, the first handle 405 is kept stationary, and the second handle 501 is rotated. The second universal coupling 502 connected to the second handle 501 rotates to drive the tilting screw 505 to rotate. The tilting screw 505 moves axially relative to the second sleeve, generating a thrust or a pull on the first cross bar 401. The bottom surfaces of the first cross bar 401 and the second cross bar 402 are fixedly connected to the flange mounting plate 413, and the flange mounting plate 413 is fixed by the pad 414. The rotary mounting plate 411 is connected, and the outer flange 409 of the ring body is fixedly connected to the rotary mounting plate 411, so the first crossbar 401 drives the outer flange 409 to generate a force after being subjected to a force, so that the outer flange 409 rotates relative to the inner flange 410, so that the rectangular slide 412, the first crossbar 401, the second crossbar 402, the first vertical rod 403, the second vertical rod 404 and the first rail 6 located above them are offset as a whole with the center of the inner flange 410 as the center point, so that the first rail 6 is tilted relative to the second rail 7. The direction of the axial movement of the tilting screw 505 relative to the second sleeve is determined according to the rotation direction of the second handle 501.

[0040] Through the above technical scheme, an experimental tilting rail capable of realizing multiple working conditions provided in Example 1 of the present invention realizes the inclination of the first rail 6 relative to the ground through the lifting component 3, and realizes the overall translation of the first rail 6 relative to the second rail 7 or the inclination of the first rail 6 relative to the second rail 7 on the same plane through the tilting component 5 and the translation component 4. The entire device can simulate the spacing between rails, the inclination angle between rails, and the inclination angle of the rails relative to the ground, and simulate the wear condition of the vehicle during operation.

[0043] When the distance between the first rail 6 and the second rail 7 is to be adjusted, the translation assembly 4 and the tilt assembly 5 are adjusted simultaneously, so that the distance moved by the translation assembly 4 is equal to the distance moved by the tilt assembly 5, so that the first rail 6 is translated as a whole relative to the second rail 7, thereby adjusting the distance between the rails;

[0044] When the first rail 6 is to be tilted relative to the second rail 7 on the same plane, the translation component 4 remains stationary, and the tilting component 5 is started, so that the tilting component 5 exerts a force on the first rail 6, causing the first rail 6 to be subjected to uneven force, and the first rail 6 is offset with the tilting component 5 as the center, ultimately achieving the tilting of the first rail 6 relative to the second rail 7 on the same plane.
