Description

Technical Field

[0001] This application relates to the field of railway track inspection technology, and in particular to a measuring device for rails. Background Technology

[0002] With the vigorous development of my country's railway industry and the increasingly dense railway network, train speeds and load capacities are constantly increasing, which places higher demands on the safety and durability of railway infrastructure, especially rails. As a core component of railway lines, rails directly bear the enormous pressure and friction of trains during operation, and their condition directly affects the safety and efficiency of railway transportation. However, in actual operation, due to the increasing service life, complex and variable climatic conditions (such as humidity, temperature changes, acid rain, etc.), and surrounding environmental pollution (such as industrial emissions and salt spray corrosion), rail corrosion problems are becoming increasingly prominent, and the corrosion situation is worsening year by year over time.

[0003] Rail corrosion not only weakens the mechanical strength of the rails but can also reduce the thickness of the rail web, thereby affecting the rail's load-bearing capacity and service life. According to relevant standards such as the "Rules for Repairing Conventional Speed ​​Railway Lines," when rail corrosion reaches a certain level—that is, when the rail web thickness is less than 8mm after rust removal treatment—it must be classified as severely damaged and immediately removed from service for replacement to prevent safety hazards caused by serious accidents such as rail breakage. Therefore, in sections with severe rail corrosion, timely and accurate measurement of the rail web thickness is crucial for assessing the rail condition, developing maintenance plans, and ensuring train operation safety.

[0004] While some tools exist on the market for measuring rail web thickness, these tools are generally bulky and heavy, causing inconvenience for field workers. Especially when multiple measurement points need to be checked quickly, the cumbersome nature of traditional tools severely impacts work efficiency.

[0038] 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.

[0039] 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.

[0040] 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.

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.

[0041] 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.

[0042] In some exemplary embodiments, such as Figures 1-6 As shown, a rail measuring device is capable of measuring rails, including but not limited to the rail web, rail top, and rail bottom. The rail web is the main supporting structure; therefore, its measurement is particularly important. The rail measuring device is primarily used to quickly and accurately measure the rail web thickness to ensure the safe use of the rail. The rail measuring device includes a measuring mechanism 1, fasteners 2, and limiting components 3.

[0043] The measuring mechanism 1 includes a first measuring part 11 and a second measuring part 12. The first measuring part 11 and the second measuring part 12 are arranged opposite to each other and are respectively mounted on the rail A.

[0044] The first measuring unit 11 is shaped to fit one side of the rail and can be equipped with a precise measuring scale or electronic sensor (not shown in the figure) for directly measuring the thickness or wear of the rail web. By reading the measurements on the first measuring unit 11, the operator can quickly understand the condition of one side of the rail web.

[0045] The second measuring unit 12 is similar to the first measuring unit 11. The second measuring unit 12 can be inserted into the other side of the rail web and is equipped with corresponding measuring tools. The second measuring unit 12 can be used alone to measure the other side of the rail web, or it can be used in conjunction with the first measuring unit 11 to measure both sides of the rail web simultaneously to assess whether the rail web is uniformly worn, thereby improving the accuracy and comprehensiveness of the measurement.

[0046] The second measuring part 12 and the first measuring part 11 have an overlapping area along the extension direction of the rail. This not only enhances the overall stability of the measuring mechanism 1 but also provides space for the installation of the fastener 2. Specifically, the fastener 2 is located in the overlapping area and is connected to both the first measuring part 11 and the second measuring part 12 to tightly connect and fix them relatively, ensuring that the measuring mechanism 1 will not loosen or shift during the measurement process, thereby guaranteeing the accuracy and reliability of the measurement results. The fastener 2 can be a standard fastener such as a bolt or nut. By tightening or loosening these fasteners, the relative position between the first measuring part 11 and the second measuring part 12 can be easily adjusted to accommodate rails of different sizes.

[0047] The limiting member 3 is disposed on the measuring mechanism 1, specifically installed on the top of the first measuring part 11 or the second measuring part 12. The limiting member 3 can abut against the top of the rail along the height direction of the rail. The function of the limiting member 3 is to further enhance the stability of the measuring device and prevent the accuracy of the measurement results from being affected by device shaking or misalignment during the measurement process. The limiting member 3 can be adjustable to accommodate rails of different heights, ensuring close contact with the rail top during each measurement.

[0048] In actual operation, the operator first inserts the first measuring part 11 and the second measuring part 12 of the measuring mechanism 1 into both sides of the rail web of the rail A to be measured, and then fixes them in place using fasteners 2. Next, the limiting member 3 is adjusted so that it abuts against the top of the rail along the rail height direction to ensure the measuring device is stable. Finally, by reading the measurement values ​​on the first measuring part 11 and / or the second measuring part 12, the thickness or wear degree of the rail web can be obtained. Based on the measurement results, the operator can determine whether the rail needs to be replaced or repaired, thereby eliminating potential safety hazards in a timely manner.

[0049] The rail measuring device in this embodiment, through the coordinated action of the measuring mechanism 1, the fastener 2, and the limiting component 3, achieves rapid and accurate measurement of the rail web thickness, providing a strong guarantee for the safe operation of railway lines.

[0050] In some exemplary embodiments, such as Figures 1-6 As shown, the fastener 2 is used to fix the first measuring part 11 and the second measuring part 12 relative to each other. The fastener 2 includes a first fastener 21 and a second fastener 22 detachably connected to the first fastener 21. The first fastener 21 is provided with a groove 211, and the second fastener 22 is disposed in the groove 211.

[0051] For example, the groove 211 in the first fastener 21 is, for example, an inverted T-shaped groove (not shown in the figure), and the second fastener 22 is, for example, an inverted T-shaped slider. The second fastener 22 is slidably connected to the first fastener 21. At this time, the first fastener 21 can be fixedly connected to one of the first measuring part 11 and the second measuring part 12, and the second fastener 22 is fixedly connected to the other. When the second fastener 22 is located in the groove 211 in the first fastener 21, the first measuring part 11 and the second measuring part 12 are relatively fixed.

[0052] Alternatively, the groove 211 in the first fastener 21 may be provided with an internal thread, and the second fastener 22 may be provided with an external thread. The second fastener 22 is connected to the internal thread of the groove 211 through its external thread. The first measuring part 11 may be provided with a first through hole 111, and the second measuring part 12 may be provided with a second through hole 121. The first through hole 111 and the second through hole 121 are coaxially stacked to facilitate the placement of the fastener 2.

[0053] The first fastener 21 has a first segment 212 and a second segment 213, which are fixedly connected. The outer diameter of the first segment 212 is larger than that of the second segment 213, and the groove 211 is located in the second segment 213. The outer diameter of the second segment 213 is smaller than that of the inner diameter of the first through hole 111 and the second through hole 121 to ensure that the second segment 213 can pass through normally. The outer diameter of the first segment 212 is larger than that of the inner diameter of the first through hole 111 and the second through hole 121, so that the first segment 212 forms a barrier with the first measuring part 11, preventing the first fastener 21 from completely passing through the first through hole 111.

[0054] The design logic of the second fastener 22 is similar to that of the first fastener 21. It is also divided into two sections. One section forms a barrier with the second measuring part 12, and the other section is adapted to the inner diameter of the groove 211 to achieve screw connection.

[0055] The second segment 213 of the first fastener 21 is passed through the first through hole 111 of the first measuring part 11 and the second through hole 121 of the second measuring part 12. The external thread portion of the second fastener 22 is screwed into the groove 211 of the first fastener 21. The second fastener 22 is rotated continuously until it can no longer rotate. At this time, the first measuring part 11 and the second measuring part 12 are clamped between the first segment 212 of the first fastener 21 and the abutting portion of the second fastener 22, forming a relatively fixed position.

[0056] In this embodiment, the fastener 2 reliably fixes the first measuring part 11 and the second measuring part 12, ensuring the stability and accuracy of the rail measuring device during the measurement process.

[0057] In some exemplary embodiments, such as Figures 1-6 As shown, the limiting component 3 is used to enhance the stability of the rail measuring device during installation, ensuring that the device will not shake or misalign during the measurement process. The limiting component 3 includes a limiting rod 31.

[0058] The number of limiting rods 31 can be one or more, depending on the actual needs and the design of the measuring device. The setting position of the limiting rods 31 is flexible. They can be set alone on the first measuring part 11, or alone on the second measuring part 12, or both the first measuring part 11 and the second measuring part 12 can be set with limiting rods 31 to further improve the stability of the measuring device during installation.

[0059] The limiting rod 31 is movable relative to the first measuring part 11 and / or the second measuring part 12, allowing the limiting rod 31 to be grounded to the top of the rail. In this embodiment, the limiting rod 31 is in the form of a threaded rod, with external threads provided on its outer surface. Correspondingly, the first measuring part 11 and / or the second measuring part 12 are provided with corresponding threaded through holes to facilitate threaded connection with the threaded rod.

[0060] By rotating the limiting rod 31, it can be moved along the threaded direction until it abuts against the top of the rail. This design is not only simple in structure but also easy to adjust, and can adapt to rails of different heights.

[0061] Alternatively, the limiting member 3 may also include a support plate 32, the number of which is the same as the limiting rod 31, with each limiting rod 31 corresponding to one support plate 32. The support plate 32 may be a flat plate structure protruding from the first measuring part 11 or the second measuring part 12, and the support plate 32 may be provided with threaded holes 321.

[0062] The limiting rod 31 is rotatably mounted on the support plate 32, i.e., it is threaded into the threaded hole 321. This design does not compromise the overall structural strength of the first measuring part 11 or the second measuring part 12, and also facilitates the installation of the limiting rod 31. By rotating the limiting rod 31, it can be moved within the threaded hole 321 and eventually abut against the top of the rail.

[0063] The design using the support plate 32 achieves greater stability because it provides additional support area, dispersing the pressure of the limit rod 31 on the measuring device. Furthermore, this design facilitates the maintenance and replacement of the limit rod 31.

[0064] In this embodiment, the limiting component 3 provides stable support for the rail measuring device, ensuring accuracy and reliability during the measurement process.

[0065] In some exemplary embodiments, such as Figures 1-6 As shown, the first measuring unit 11 is used to measure the web of the rail. The first measuring unit 11 includes a support rod 112, a first support rod 113, a second support rod 114, and a measuring ruler 115.

[0066] The support rod 112, as the main structure of the first measuring part 11, serves to support and connect other components. Its material and strength need to be selected according to the actual measurement requirements to ensure stability during the measurement process.

[0067] The first support rod 113 and the second support rod 114 are respectively connected to the support rod 112 and are spaced apart along the height direction of the rail. A clamping space 116 is formed between the first support rod 113, the support rod 112, and the second support rod 114, and the clamping space 116 is configured to accommodate the top of the rail. The size and shape of the clamping space 116 are designed to accommodate the top of the rail, thereby achieving initial positioning and fixation of the rail.

[0068] A measuring scale 115 is rotatably mounted on a support rod 112, allowing the measuring scale 115 to be adjusted as needed to maintain its relative distance to the rail web, and ultimately to abut against the rail web. The measuring scale 115 may be equipped with precise graduations or an electronic sensor (not shown) for measuring the thickness or wear of the rail web. When the measuring scale 115 abuts against the rail web, the operator can obtain measurement data by reading the graduations or receiving signals from the electronic sensor.

[0069] In practice, the operator first places the top of the rail into the clamping space 116 formed by the first support rod 113, the support rod 112, and the second support rod 114 to achieve initial positioning and fixation of the rail. Then, the operator rotates the measuring ruler 115 until it abuts against the rail web. Finally, by reading the scale on the measuring ruler 115 or receiving signals from the electronic sensor, the operator can obtain data on the thickness or wear level of the rail web and determine whether the rail needs replacement or repair based on this data.

[0070] In this embodiment, as Figures 1-6 As shown, to further enhance the structural strength and stability of the first measuring part 11, the first measuring part 11 also includes a reinforcing rib 117. The reinforcing rib 117 is sandwiched between the first support rod 113 and the second support rod 114. The reinforcing rib 117 is fixedly connected to the support rod 112, the first support rod 113, and the second support rod 114 to form a stable overall structure. Among them, the first support rod 113, the reinforcing rib 117, and the second support rod 114 together construct the clamping space 116.

[0071] Exemplarily, the clamping space 116 includes a first inclined surface 1131 disposed on the first support rod 113, a second inclined surface 1171 disposed on the reinforcing rib 117, and a third inclined surface 1141 disposed on the second support rod 114. The first inclined surface 1131 is adapted to the top of the rail top to ensure tight contact during measurement and guarantee accuracy. The second inclined surface 1171 abuts against the side of the rail top, further enhancing clamping stability, and its design allows the reinforcing rib 117 to better adapt to the shape of the rail top, ensuring no shaking or misalignment occurs during measurement. The third inclined surface 1141 is adapted to the bottom of the rail top, also for tight contact during measurement.

[0072] The clamping space 116, through the first inclined surface 1131, the second inclined surface 1171, and the third inclined surface 1141, tightly abuts against the top, side, and bottom of the rail, achieving a stable clamping of the rail. This design not only improves the accuracy of the measurement but also ensures the stability of the device during the measurement process.

[0073] In this embodiment, as Figures 1-6 As shown, the first measuring unit 11 has a connecting rod 118, which is located on the side of the first support rod 113 away from the second support rod 114, and is connected to the support rod 112. The material, size, shape, and relative distance between the connecting rod 118 and the first support rod 113 can be optimized according to the actual measurement requirements and the overall design of the measuring device to ensure that it has sufficient strength and rigidity.

[0074] The connecting rod 118 overlaps with a portion of the second measuring part 12. This overlapping arrangement not only enhances the connection stability between the first measuring part 11 and the second measuring part 12, but also helps to achieve collaborative work between the two measuring parts during the measurement process.

[0075] The overlapping area between the connecting rod 118 and the second measuring part 12 needs to be designed according to the specific structural and functional requirements of the two measuring parts. The overlapping area should ensure that there is sufficient contact area between the connecting rod 118 and the second measuring part 12 to withstand various forces that may be generated during the measurement process.

[0076] In this embodiment, as Figures 1-6 As shown, the second measuring unit 12 includes a measuring body 123 and an extension rod 122. The measuring body 123 is symmetrically arranged with the first measuring unit 11 along the height direction of the rail, that is, its shape is the same as that of the first measuring unit 11. Therefore, it has similar functions and structural features as the first measuring unit 11. Since the specific structure of the measuring body 123 is similar to that of the first measuring unit 11, it will not be described again here.

[0077] The extension rod 122 is connected to the measuring body 123, and its function is to overlap with the connecting rod 118 of the first measuring part 11, thereby enhancing the connection stability between the two measuring parts. The material, size, and shape of the extension rod 122 can be optimized according to the actual measurement requirements and the overall design of the device.

[0078] In this embodiment, as Figures 1-6 As shown, the connecting rod 118 has a first through hole 111, and the extension rod 122 has a second through hole 121. The first through hole 111 and the second through hole 121 are coaxially stacked, providing a channel for the fastener 2 to pass through. The fastener 2 passes through the first through hole 111 and the second through hole 121, fastening the connecting rod 118 and the extension rod 122 together. This connection method is not only simple and reliable, but also convenient for disassembly and maintenance.

[0079] In actual operation, the operator first aligns the extension rod 122 of the second measuring part 12 with the connecting rod 118 of the first measuring part 11, ensuring they overlap and that the first through hole 111 and the second through hole 121 are coaxially aligned. Then, the fastener 2 is passed through these two through holes and tightened, thus completing the connection between the second measuring part 12 and the first measuring part 11. After connection, rail measurement can begin. For disassembly or maintenance, simply loosening the fastener 2 allows for easy separation of the two measuring parts.

[0080] In this embodiment, the second measuring unit 12 achieves a stable connection with the first measuring unit 11, providing a strong guarantee for the accurate measurement of the rail measuring device. At the same time, this connection method facilitates the installation, disassembly, and maintenance of the device, improving work efficiency and ease of use.

[0081] 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.

[0082] 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.
