Description
Technical Field
[0001] This application relates to the field of railway testing technology, and in particular to railway track calibration devices. Background Technology
[0002] With the rapid development of the railway industry and the continuous increase in freight volume, track maintenance and repair work has become more frequent, and track cleaning and tamping operations have also become more frequent. Before, during, and after the operation, it is necessary to accurately measure the height of the top surface of the rails to ensure that the rail top surface height is correct after cleaning and tamping, and also to restore the rail position to its pre-operation state or adjust it to the designated state.
[0003] The process of adjusting the condition of the rails described above requires the use of a measuring instrument. This instrument uses a well-maintained rail adjacent to the rail to be adjusted as a benchmark, measuring the relative condition between the rail to be adjusted and the benchmark rail. The condition of the rail to be adjusted is then adjusted based on the measurement results. However, traditional measuring instruments are typically placed directly on the top surface of the rail, which results in unstable placement and low positioning accuracy. Utility Model Content
[0004] Therefore, it is necessary to provide a railway track calibration device that uses the side face of the rail and sleepers for support and positioning, thereby improving placement stability and positioning accuracy.
[0005] This application provides a railway track calibration device for detecting the height and spacing of railway rails. The railway track calibration device includes:
[0006] Measuring instrument;
[0007] A measuring instrument bracket is used to support and position the measuring instrument.
[0008] The measuring instrument bracket includes a bracket body, a first positioning part, and a second positioning part. The bracket body is used to place the measuring instrument. The first positioning part and the second positioning part are disposed on the bracket body. The first positioning part is used to abut against the top surface of the sleeper of the benchmark rail adjacent to the rail to be adjusted, and the second positioning part is used to abut against the side surface of the benchmark rail.
[0009] In one embodiment, the railway track calibration device further includes:
[0010] A measuring ruler, which has a scale, is positioned on the rail to be adjusted along the height direction of the rail. The measuring instrument is used to transmit a measuring signal from the benchmark rail to the measuring ruler.
[0011] In one embodiment, the measuring instrument is configured as an infrared measuring instrument capable of emitting infrared light toward the measuring ruler.
[0012] In one embodiment, the support body includes:
[0013] A support rod is provided that can extend along the height direction of the benchmark rail, and the first positioning part and the second positioning part are provided on the support rod;
[0014] A support plate is disposed at the top of the support rod, and the measuring instrument is placed on the support plate.
[0015] In one embodiment, a positioning protrusion is provided on the surface of the support plate opposite to the support rod, and the measuring instrument is placed against the positioning protrusion.
[0016] In one embodiment, the first positioning part has a first abutting surface for abutting against the top surface of the sleeper of the benchmark rail; the first abutting surface is perpendicular to the extending direction of the support rod.
[0017] In one embodiment, the second positioning part has a second abutting surface for abutting against the side surface of the benchmark rail; the second abutting surface is perpendicular to the first abutting surface.
[0018] In one embodiment, the second positioning part includes:
[0019] A connecting rod, the first end of which is connected to the support rod;
[0020] A positioning ruler, one end of which is connected to the second end of the connecting rod, and the surface of the positioning ruler facing away from the connecting rod is used to abut against the side surface of the benchmark rail.
[0021] In one embodiment, the positioning ruler includes at least two abutting portions, each abutting portion being spaced apart along a direction perpendicular to the extension of the support rod.
[0022] In one embodiment, the measuring ruler includes a scale portion and a third positioning portion, wherein the scale portion is capable of extending along the height direction of the rail to be adjusted;
[0023] The third positioning part is disposed at one end of the extension direction of the scale part, the third positioning part has a third abutting surface, the third abutting surface is perpendicular to the extension direction of the scale part, and can abut against the top surface of the rail to be adjusted.
[0024] The aforementioned railway track calibration device uses a measuring instrument bracket to support and position the measuring instrument, thereby determining the relative position between the measuring instrument and the benchmark rail, achieving higher measurement accuracy. By configuring the measuring instrument bracket to include a bracket body, a first positioning part, and a second positioning part, with the first positioning part abutting against the top surface of the sleeper of the benchmark rail and the second positioning part abutting against the side surface of the benchmark rail, the bracket body is positioned in two perpendicular directions. Compared to placing the measuring instrument bracket directly on the top surface of the benchmark rail, this significantly improves the stability and positioning accuracy of the measuring instrument bracket.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0034] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0035] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0036] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0037] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0038] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.
[0039] See Figure 1 , Figure 1 A schematic diagram of a railway track calibration device provided in one embodiment of this application is shown. The diagram shows two railway lines, each including two rails. On the right are two rails 100 to be adjusted, which have undergone cleaning, tamping, and other operations, and need to be adjusted to their pre-operation state or a specified state. On the left are two benchmark rails 200, which have not yet undergone operation and are in relatively good working condition. Therefore, when adjusting the rails 100 to be adjusted, the benchmark rails 200 are usually used as the measurement reference.
[0040] This application provides a railway track calibration device for detecting the height and spacing of railway rails, specifically measuring the height difference and spacing between the rail to be adjusted 100 and the benchmark rail 200.
[0041] The railway track calibration device includes a measuring instrument 1 and a measuring instrument support 2, which supports and positions the measuring instrument 1. The measuring instrument support 2 includes a support body 21, a first positioning part 22, and a second positioning part 23. The support body 21 holds the measuring instrument 1. The first positioning part 22 and the second positioning part 23 are disposed on the support body 21. The first positioning part 22 abuts against the top surface of the sleeper of the benchmark rail 200 adjacent to the rail 100 to be adjusted, and the second positioning part 23 abuts against the side surface of the benchmark rail 200.
[0042] The railway track calibration device provided in this application embodiment supports and positions the measuring instrument 1 by setting a measuring instrument bracket 2 to determine the relative position between the measuring instrument 1 and the benchmark rail 200, thereby achieving higher measurement accuracy. By setting the measuring instrument bracket 2 to include a bracket body 21, a first positioning part 22 and a second positioning part 23, with the first positioning part 22 abutting against the top surface of the sleeper of the benchmark rail 200 and the second positioning part 23 abutting against the side surface of the benchmark rail 200, the bracket body 21 is positioned in two perpendicular directions. Compared with the scheme of placing the measuring instrument bracket 2 directly on the top surface of the benchmark rail 200, the placement stability and positioning accuracy of the measuring instrument bracket 2 are greatly improved.
[0043] Specifically, both the rail to be adjusted 100 and the benchmark rail 200 are I-beam type rails, including a top crossbeam, a middle vertical beam, and a bottom crossbeam. The second positioning part 23 can abut against the side surface of the top crossbeam. This arrangement allows the abutment point of the second positioning part 23 to be kept at a greater distance from the abutment point of the first positioning part 22, which is more conducive to the stable placement of the support body 21. Of course, the second positioning part 23 can also abut against the middle vertical beam or the bottom crossbeam, which can also achieve the horizontal positioning of the support body 21.
[0044] In some embodiments, please refer to... Figure 1 The railway track calibration device also includes a measuring ruler 3, which has graduations. The measuring ruler 3 can be positioned on the rail 100 to be adjusted along its height direction. The measuring instrument 1 transmits a measurement signal from the benchmark rail 200 to the measuring ruler 3. By reading the graduations on the measuring ruler 3 at the position where the measuring signal from the measuring instrument 1 is received, the height of the rail 100 to be adjusted can be indirectly determined, and the height of the rail 100 to be adjusted can be adjusted accordingly. By transmitting a signal from the measuring instrument 1 to the measuring ruler 3, the distance between the measuring instrument 1 and the measuring ruler 3 can be determined, thereby indirectly determining the distance between the rail 100 to be adjusted and the adjacent benchmark rail 200. The horizontal position of the rail 100 to be adjusted can be adjusted according to this distance.
[0045] In some embodiments, the measuring instrument 1 is configured as an infrared measuring instrument 1, capable of emitting infrared rays to the measuring ruler 3. The infrared rays are emitted in a straight line along the extension direction of the vertical guide rail 200, and the measuring ruler 3 needs to be installed on the emission path of the infrared rays so that the infrared rays accurately hit the measuring ruler 3.
[0046] Please see Figure 1 and Figure 2 , Figure 2 A schematic diagram of the structure of the measuring instrument bracket 2 provided in one embodiment of this application is shown. In some embodiments, the bracket body 21 includes a support rod 211 and a support plate 212. The support rod 211 can extend along the height direction of the benchmark rail 200, and a first positioning part 22 and a second positioning part 23 are disposed on the support rod 211. The support plate 212 is disposed at the top of the support rod 211, and the measuring instrument 1 is placed on the support plate 212. By setting the support rod 211 and the support plate 212 at the top of the support rod 211, the support plate 212 is positioned at a higher position, and the measuring instrument 1 is placed on the support plate 212, thereby placing the measuring instrument 1 at a higher position, which is convenient for the operator to operate without frequent bending over.
[0047] In some embodiments, a positioning protrusion 213 is provided on the surface of the support plate 212 facing away from the support rod 211 (i.e., the support surface of the support plate 212), and the measuring instrument 1 is placed against the positioning protrusion 213. By setting the positioning protrusion 213 to position the measuring instrument 1, the relative position of the measuring instrument 1 and the benchmark rail 200 is determined, which makes it easier to calculate the height difference and spacing between the rail 100 to be adjusted and the benchmark rail 200 in the subsequent process.
[0048] Optionally, the support surface of the support plate 212 is set perpendicular to the extension direction of the support rod 211 so that the support surface of the support plate 212 is in a horizontal state, which is more conducive to the stable placement of the measuring instrument 1 and also more conducive to the positioning of the measuring instrument 1.
[0049] In some embodiments, the first positioning part 22 has a first abutting surface 220, which abuts against the top surface of the sleeper of the benchmark rail 200, and the first abutting surface 220 is perpendicular to the extending direction of the support rod 211. Thus, when the first abutting surface 220 abuts against the top surface of the sleeper of the benchmark rail 200, the support rod 211 can be kept vertical, thereby keeping the support surface of the support plate 212 horizontal.
[0050] In some embodiments, the second positioning part 23 has a second abutment surface 230, which abuts against the side elevation of the benchmark rail 200 and is perpendicular to the first abutment surface 220. This allows the second abutment surface 230 and the first abutment surface 220 to position the support body 21 in two perpendicular directions. Given the current rail structure where the top surface of the sleeper is perpendicular to the side elevation of the benchmark rail 200, it ensures that both the first abutment surface 220 and the second abutment surface 230 are fully engaged, preventing one from being suspended or only partially engaged.
[0051] In some embodiments, the second positioning part 23 includes a connecting rod 231 and a positioning ruler 232. The first end of the connecting rod 231 is connected to the support rod 211, and one end of the positioning ruler 232 is connected to the second end of the connecting rod 231. The surface of the positioning ruler 232 facing away from the connecting rod 231 is used to abut against the side surface of the benchmark rail 200. That is, the surface of the positioning ruler 232 facing away from the connecting rod 231 forms the aforementioned second abutment surface 230. By providing the support rod 211, the distance between the second abutment surface 230 and the support rod 211 is increased, so as to avoid the second abutment surface 230 failing to abut against the side surface of the benchmark rail 200 due to interference between the first positioning part 22 and the benchmark rail 200.
[0052] Optionally, the positioning ruler 232 includes at least two abutment portions 2321, each abutment portion 2321 being spaced apart along the extending direction of the vertical support rod 211. This arrangement ensures that the positioning ruler 232 maintains a good positioning effect while reducing material usage and thus helping to reduce the weight of the device.
[0053] Please see Figure 1 and Figure 3 , Figure 3 A schematic diagram of the structure of a measuring ruler 3 provided in one embodiment of this application is shown. In some embodiments, the measuring ruler 3 includes a scale portion 31 and a third positioning portion 32. The scale portion 31 can extend along the height direction of the rail 100 to be adjusted. The third positioning portion 32 is disposed at one end of the extension direction of the scale portion 31. The third positioning portion 32 has a third abutment surface 320, which is perpendicular to the extension direction of the scale portion 31 and can abut against the top surface of the rail 100 to be adjusted. During installation, the third abutment surface 320 is made to fit against the top surface of the rail 100 to be adjusted so that the scale portion 31 is in a vertical state, thereby accurately displaying the height value and avoiding inaccurate measurement due to the skewness of the scale portion 31.
[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0055] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
