With the development of the railway industry, higher requirements have been put forward for parameters such as high-speed passing performance, stability, and load capacity of railway tracks, and the requirements for the strength and hardness of frogs have also been continuously improved.

[0003] Due to the irregularity of the cross-section of the frog heart rail profile, for existing general-purpose measuring tools, due to the influence of the reduction value at the front end of the heart rail, when measuring the heart rail width values of different sections, the values need to be continuously adjusted, resulting in large measurement difficulties, cumbersome operations, large errors, and low time efficiency. Moreover, it is impossible to detect the matching degree of the frog heart rail profile, and it is also difficult to achieve high-efficiency on-line detection, causing difficulties in on-site detection for maintenance personnel and other problems.

[0004] Therefore, in order to facilitate the large-scale in-plant production and manufacturing of the same type of frogs, while meeting the on-line detection and timely maintenance requirements of maintenance personnel, ensuring stable and reliable quality, and guaranteeing the safety of train operation, the following improved technical solutions are proposed.

Specific implementation manner

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying Figure 1-8 , in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] A detection method for a multi-functional detection ruler of the frog heart rail cross-section, including a multi-functional detection ruler for the frog heart rail cross-section, and the method includes the following steps:

[0038] Step S1, pre-detection calibration: Select a suitable detection ruler according to the frog type to be detected and the width value of the frog heart rail head; Place the detection ruler on a horizontal plane, and observe whether the detection ruler has bending deformation, whether there are nicks, burrs, and measurement error influencing factors caused by knocking on the special cross-section control gauge 2 for the frog heart rail, the comparison and detection card slot 3 for the frog heart rail profile, and the limit card slot 4 for the inlaid block or wing rail; Then place the detection ruler at the standard frog measurement point, ensure that the vertical wear measuring ruler 5 for the frog heart rail and the vertical wear measuring ruler 6 for the inlaid block or wing rail are flush with the profiles of the frog heart rail and the wing rail, and make the scales of the vertical wear measuring ruler 5 for the frog heart rail and the vertical wear measuring ruler 6 for the inlaid block or wing rail both at the zero scale line. The pre-detection calibration step is used to ensure the usability of the detection ruler, and thus ensure the reliability of the detection use.

[0039] Step S2, Detection and Use: The detection and use includes the following: namely, step S201, in-factory manufacturing dimension control use; and step S202, on-line circuit detection and repair use.

[0040] Regarding step S201, in-factory manufacturing dimension control use: That is, when manufacturing the frog in the factory, the present invention is used for detection, and the method steps are as follows:

[0041] Step S201, in-factory manufacturing dimension control use includes the following steps:

[0042] Step S2011, (as Figure 3 , Figure 4 shown) Place the special section control gauge 2 of the detection ruler on the frog heart rail of the whole set, make the reference ruler 1 closely adhere to the top surface of the frog wing rail and serve as the horizontal reference. Starting from the theoretical tip of the heart rail, the rail head width of the heart rail section increases from small to large. Slide the detection ruler along the direction from small to large until the detection ruler can no longer move. The position where it can no longer slide is the special section position of the heart rail corresponding to this specification of the detection ruler.

[0043] Step S2012, Mark this corresponding position, that is, the position where the detection ruler can no longer move, observe the matching degree between the special section control gauge 2 of the heart rail and the heart rail head, and judge the machining accuracy of the heart rail head width. If it fits perfectly, the heart rail is qualified; otherwise, it is unqualified.

[0044] In the above embodiment, further: In step S201, the common heart rail section rail head width values of the fixed frog are 20mm, 30mm, 40mm, 45mm, 50mm, that is, mark and detect at the above width dimension positions.

[0045] Step S2013, When detecting the inlay block or wing rail (as Figure 5 , Figure 6As shown in the figure), for the 180° flipping detection ruler, the reference ruler 1 is attached to the top surface of the wing rail, that is, the horizontal positioning reference of the detection ruler is found; then, the inlaid block or the wing rail limit card slot 4 on the right side is closely attached to the inlaid block or the wing rail, and the matching condition between the inlaid block or the wing rail limit card slot 4 and the profile of the inlaid block or the wing rail is observed to judge the machining accuracy of the profile of the inlaid block or the wing rail. If it fits perfectly, it is qualified; otherwise, it is unqualified. On the basis that the inlaid block or the wing rail limit card slot 4 perfectly matches the profile of the inlaid block or the wing rail, the inlaid block or the wing rail limit card slot 4 is used as the right limit position reference: move the detection ruler to the right until the inlaid block or the wing rail limit card slot 4 cannot move to the right anymore because it perfectly matches the profile of the inlaid block or the wing rail, which proves that the positioning reference of the detection ruler is completely found: at this time, observe the matching condition between the checking card slot 3 of the switch rail profile comparison and the switch rail profile to judge the machining accuracy of the switch rail profile; if it fits perfectly, it proves that the switch rail profile is correct; otherwise, it is unqualified. At the same time, judge whether the relative position relationship between the switch rail and the inlaid block or the wing rail meets the requirements of the drawing design. If it fits, the relative position is qualified; otherwise, it is unqualified.

[0046] Regarding step S202, for on-line detection and maintenance of the line: that is, the present invention can also be used for on-line detection and maintenance.

[0047] Step S202, the on-line detection and maintenance of the line includes the following steps:

[0048] Step S2021, according to the frog number to be detected, use a tape measure to measure and mark the position of the special section of the switch rail corresponding to the frog to be measured; the common rail head width values of the special section of the switch rail of the fixed frog are 20mm, 30mm, 40mm, 45mm, 50mm. The purpose is still to mark at the above width dimension positions by pulling a wire for detection.

[0049] Step S2022, (as Figure 3 , Figure 4 shown), then press the reference ruler 1 of the detection ruler tightly against the top surface of the wing rail, and observe the matching degree between the special section control gauge 2 of the switch rail and the rail head of the switch rail. Similarly, the profile and relative position of the switch rail are detected by the special section control gauge 2 of the switch rail with an integrated structure shape.

[0050] Specifically: in the above embodiment, preferably: in step S202, when observing the matching degree between the special section control gauge 2 of the switch rail and the rail head of the switch rail: if the detection ruler is lifted, it means that the rail head width is too wide and the switch rail needs to be polished and maintained; if there is a gap between the special section control gauge 2 of the switch rail and the rail head, it means that the rail head width is smaller than the theoretical value.

[0051] More specifically: In the above embodiments, further: To detect the clearance value: In step S202, when there is a clearance between the special section control gauge 2 of the switch rail and the rail head, a feeler gauge is used in combination to measure the wear degree of the switch rail head. The structure of the feeler gauge is a prior art, and its usage method will not be elaborated.

[0052] Step S2023. When detecting the inlay block or the wing rail (such as Figure 5 , Figure 6 shown), flip the inspection gauge by 180°. Press the reference gauge 1 against the top surface of the wing rail to provide a horizontal positioning reference. Then, press the inlay block or wing rail limit slot 4 against the inlay block or wing rail, and observe the matching condition between the inlay block or wing rail limit slot 4 and the contour of the inlay block or wing rail. If it fits perfectly, it proves that the inlay block or wing rail is qualified. If you want to detect the wear degree of the inlay block or wing rail: Slide the vertical wear measurement gauge 6 of the inlay block or wing rail, and measure the deviation value between the contour of the inlay block or wing rail and its standard contour according to the reading. On the basis that the relative position relationship and the contour of the inlay block or wing rail are qualified: Press the reference gauge 1 against the top surface of the wing rail, and move the inspection gauge to the right until the inlay block or wing rail limit slot 4 fits perfectly with the inlay block or wing rail and the inspection gauge can no longer move. At this time, the inlay block or wing rail provides a right limit detection and positioning reference: After fixing the inspection gauge, then observe the matching condition between the heart rail contour comparison detection slot 3 and the heart rail contour. If it fits perfectly, it is qualified; otherwise, maintenance is required. If you want to detect the wear amount of the heart rail: Slide the vertical wear measurement gauge 5 of the heart rail, and measure the deviation value between the contour of the heart rail profile and its standard contour according to the reading.

[0053] In the above embodiments, preferably: The multi-functional inspection gauge for the switch rail heart rail section is of an integral structure. Using an integral structure, the operation is relatively simple, the structure is compact, the processing and manufacturing are convenient, it is economical and practical.

[0054] (such as Figure 1 , Figure 2 shown) In the above embodiments, further: The multi-functional inspection gauge for the switch rail heart rail section has a reference gauge 1 that is horizontally installed on the top of the wing rail and serves as the horizontal reference of the inspection gauge. In the above embodiments, further: When measuring, the reference gauge 1 is used to horizontally fit against the top surface of the wing rail and serves as the horizontal positioning reference for the entire multi-functional inspection gauge for the switch rail heart rail section.

[0055] Embodiment 1 of the reference gauge 1: (such as Figure 1 shown) Both ends of the reference gauge 1 are straight. It is used for the multi-functional inspection gauge of the heart rail section of the ordinary type of frog / welded frog.

It is used for the use of the multifunctional detection ruler for the cross section of the wing rail type frog.

[0057] The upper end surface of the vertical surface of the reference ruler 1 is provided with an integrated fixed structure for detecting the size and position of the heart rail special section control caliper 2. The integrated structure of the heart rail special section control caliper 2 saves the adjustment and dialing steps, and the reference ruler can be detected after positioning, which simplifies the operation and is conducive to improving the detection efficiency.

[0058] In the above embodiments, preferably: Figure 1 , Figure 2 The control gauge 2 for the special cross section of the heart rail is a U-shaped slot structure, and the U-shaped slot structure has a bevel 201 with the same slope as the working edge of the heart rail. The claw position size of the U-shaped slot structure is the design width value of the head of the heart rail with a special cross section of the heart rail.

[0059] The lower end surface of the vertical surface of the reference ruler 1 is provided with a heart rail profile comparison detection card slot 3 of an integrated structure for detecting the heart rail profile and relative position, and an inlay block or wing rail limit card slot 4 of an integrated structure for detecting the inlay block or wing rail profile and relative position. The heart rail profile comparison detection card slot 3 and the inlay block or wing rail limit card slot 4 are all integrated structures, which saves the adjustment and toggling steps, simplifies the operation, and the reference ruler can be detected after positioning, which is conducive to improving the detection efficiency.

[0060] In the above embodiment, further: the center rail profile comparison detection card slot 3 profile includes one or more tangent arcs and inclined surfaces; the relative position relationship of the profile is consistent with the product design value.

[0061] In the above embodiment, further: the mosaic block or wing rail limit slot 4 can be used to detect the mosaic block or wing rail profile, and can also be used as a limit position for the mosaic block or wing rail to ensure the stability of the measurement reference; the outline of the mosaic block or wing rail limit slot 4 matches the designed outline of the mosaic block or wing rail, and includes one or more tangent arcs and inclined surfaces; the relative position relationship of the outline of the mosaic block or wing rail limit slot 4 is consistent with the product design value.

The heart rail vertical wear measuring ruler 5 is used to detect the vertical wear amount of the heart rail; the mosaic block or wing rail vertical wear measuring ruler 6 is used to detect the vertical wear amount of the mosaic block or wing rail.

[0063] In the above embodiment, preferably: the center rail vertical wear measuring ruler 5, the inlay block or the wing rail vertical wear measuring ruler 6 are installed on the vertical surface of the reference ruler 1. The specific installation structure is bonding or embedded installation.

[0064] The vertical wear measuring scale 5 of the switch rail is arranged between the working edge of the switch rail and the center line of the switch rail cross-section; the vertical wear measuring scale 6 of the inlay block or wing rail is arranged between the working edge of the inlay block or wing rail and the center line of the inlay block or wing rail. That is, it is aligned with the wear interval at the top of the switch rail, inlay block or wing rail for detection.

[0065] In the above embodiment, further: (as Figure 8 shown) The vertical wear measuring scale 5 of the switch rail and the vertical wear measuring scale 6 of the inlay block or wing rail have a vertical wear measuring scale body 601 with an overall flat plate structure. The measuring contact position at the bottom end of the vertical wear measuring scale body 601 is designed as a triangular knife edge 602; when measuring the wear amount, the edge tip of the triangular knife edge 602 directly contacts the detection position on the top surface of the switch rail or inlay block; the upper part of the triangular knife edge 602 is a rectangular structure 603, and sliding grooves 604 are arranged on both sides of the rectangular structure 603; the sliding grooves 604 enable the vertical displacement of the vertical wear measuring scale body 601 relative to the sliding grooves 604 in the vertical direction; a vertical moving groove 605 is opened on the right side in the middle of the rectangular structure 603 and is equipped with a locking screw 606, and the locking screw 606 locks the position of the vertical wear measuring scale body 601; after the measurement is completed, the locking screw 606 is tightened to ensure accurate reading; standard scale lines 607 are printed on the vertical wear measuring scale body 601 to realize the on-line measurement of the vertical wear amount.
