Description

Technical Field

[0001] The invention relates to the technical field of wear measurement of fixed frogs for single turnouts, and in particular to a wear measurement device for fixed frogs for single turnouts. Background Art

[0002] At present, the fixed frog wear of single turnout is generally measured using a fixed frog wear measuring ruler. During measurement, the measuring device body is generally fixed at a fixed point with a width of 30mm on the top of the heart rail through a positioning hook. The heart rail vernier main ruler determines the position of the highest point on the top of the heart rail, and cooperates with the reading of the heart rail vernier secondary ruler to measure the vertical wear of the heart rail; the wing rail vernier main ruler determines the vertical wear point of the wing rail, and cooperates with the reading of the wing rail vernier secondary ruler to measure the vertical wear of the wing rail. After measuring the vertical wear values ​​of the heart rail and wing rail, they need to be compared with the values ​​of the unworn heart rail and wing rail when on the track to obtain the vertical wear amount of the heart rail and wing rail.

[0003] The existing fixed frog wear measuring scale still has the following problems: First, due to the interaction between the wheel and the rail, the triangular wear zone where the heart rail and the wing rail are jointly subjected to force will cause serious wear of the lateral wear measurement points of the wing rail, but the existing instruments cannot measure the wear of the lateral wear measurement points of the wing rail; second, due to the influence of the fixed frog structure, that is, the limitations of the shape, space, and relative position of the heart rail and the wing rail, the existing instruments cannot guarantee the accurate positioning of the vertical wear measurement points of the wing rail (the center of the light band of the wing rail) corresponding to each wear stage, resulting in deviations in the data measured by different personnel even if the same personnel uses the same instrument, and the measurement results are relatively discrete; finally, the measurement data needs to be compared with the corresponding section when there is no vertical wear when it is just put on the track (newly produced) to determine the degree of wear, but the existing instruments cannot directly compare during measurement, that is, it is impossible to timely and effectively analyze the rail wear development rate and rail replacement cycle on site, which has an adverse impact on maintenance and repair decisions.

The third threaded rod 914 is manually controlled to rotate, thereby driving the top of the moving plate 913 to approach the bottom of the rail. Because the bottom of the rail is at the same height, by energizing the electromagnet 915, the moving plate 913 can be well set at the bottom of the rail, and then the supporting bar 1 can be well supported at various positions on the top of the wing rail. At this time, the device can measure multiple data, making the detected data more accurate. More accurate; a rotating groove 904 is provided on one side of the cavity 901, and a round rod 905 is fixedly connected to the inner wall of the rotating groove 904, and a second gear 906 is fixedly connected to the surface of the round rod 905, and the second gear 906 and the first gear 903 are meshed with each other. The second gear 906 is manually controlled to rotate, which drives the first gear 903 to rotate. Since the first gear 903 is sleeved in the middle of the second threaded rod 902, the first gear 903 will also drive the second threaded rod 902 to rotate; a positioning groove 907 is provided on one side of the support bar 1, and a U-shaped plate 908 is slidably connected to the inner wall of the positioning groove 907. One side of the U-shaped plate 908 is arranged on the side of the second gear 906 away from the cavity 901, and one side of the inner wall of the positioning groove 907 is fixedly connected to the second elastic Spring 909, one side of the second spring 909 close to the inner wall of the positioning groove 907 is fixedly connected to one side of the U-shaped plate 908, a locking groove 910 is provided on one side of the U-shaped plate 908, and the inner wall of the locking groove 910 is provided with a rubber strip 911, and the rubber strip 911 is fixedly connected to one side of the support strip 1; when the support device 9 is used, the U-shaped plate 908 is manually controlled to slide on the inner wall of the positioning groove 907, so that the U-shaped plate 908 slides to one side of the second gear 906, and the second spring 909 is controlled to squeeze the U-shaped plate 908 in the direction away from the positioning groove 907, and the rubber strip 911 is clamped to the inside of the locking groove 910, thereby well restricting the U-shaped plate 908 to one side of the second gear 906 to avoid accidentally touching the second gear 906.

[0027] Working principle: When using the measuring device, the main body of the measuring device is generally fixed at a fixed point 30mm wide on the top of the heart rail through a positioning hook. The heart rail vernier main scale determines the position of the highest point on the top surface of the heart rail and directly measures the vertical wear of the heart rail; the wing rail vernier main scale 7 determines the vertical wear point of the wing rail, and cooperates with the wing rail vernier secondary scale 6 to read the reading to measure the vertical wear of the wing rail. After measuring the wear values ​​of the heart rail and wing rail, they need to be compared with the unworn heart rail and wing rail values ​​measured by the instrument to obtain the final vertical wear values ​​of the heart rail and wing rail; when using the detection device 8, first manually slide the fixing strip 803 into the inside of the fixing groove 802 opened on the top of the fixing plate 801, and then pass the rectangular strip 814 through the support block 810 so that the rectangular strip 814 is set on the top of the fixing plate 801, and then squeeze the rubber block 815 to the side of the fixing plate 801 away from the support block 810, and pull the connecting block 813 in the direction close to the support block 810 by controlling the first spring 812, so that the rectangular strip 814 is restricted to the top of the fixing plate 801. Similarly, the fixing strip 803 can be clamped inside the fixing groove 802 through the rectangular strip 814, so that the connecting frame 804 is provided with one side of the wing rail vernier secondary scale 6; finally, the first threaded rod 807 is manually controlled to rotate, so that the moving strip 805 threadedly sleeved on the surface of the first threaded rod 807 slides on the inner wall of the connecting frame 804, and the positioning rod 806 fixed on one side of the bottom of the moving strip 805 is pressed on the side wear measurement point of the wing rail, thereby driving the connecting strip 808 to move on the surface of the connecting frame 804. By observing the scale 809 set on the surface of the connecting frame 804, the moving distance of the moving strip 805 can be read, and the current measured data and the previous data are displayed on the display screen 10. By comparison, the side wear value of the wing rail can be obtained, and the wear development rate of the rail can be analyzed in time on site; when the supporting device 9 is used, since the second gear 906 and the first gear 903 are meshed with each other, the second gear 906 is manually controlled to drive the first gear 903 to rotate, and at the same time, the second threaded rod 902 will also rotate with the first gear 903. Because the thread direction on the surface of the second threaded rod 902 is opposite from the middle to both sides, the L-shaped plates 912 on both sides will slide into the inside of the cavity 901, so that the L-shaped plates 912 are squeezed on both sides of the wing rail; the third threaded rod 914 is manually controlled to rotate, driving the top of the moving plate 913 to approach the bottom of the rail, because the bottom of the rail is at the same High, by energizing the electromagnet 915, the movable plate 913 is set at the bottom of the rail, so that the support strip 1 is well supported at various positions on the top of the wing rail, and multiple data can be measured, making the measured data more accurate; when the support device 9 is used, the U-shaped plate 908 is manually controlled to slide on the inner wall of the positioning groove 907, so that the U-shaped plate 908 slides to one side of the second gear 906, and the second spring 909 is controlled to squeeze the U-shaped plate 908 in the direction away from the positioning groove 907, and the rubber strip 911 is stuck in the inside of the locking groove 910, thereby well limiting the U-shaped plate 908 to one side of the second gear 906 to avoid accidentally touching the second gear 906.
