Description

Technical Field

[0001] This application relates to the field of railway measurement equipment technology, and in particular to a warning marker measuring device. Background Technology

[0002] Warning markers are used to indicate that locomotives and rolling stock are not allowed to cross towards turnouts or track intersections when stopped, to prevent lateral collisions between locomotives and rolling stock on the stopped track and those on adjacent tracks. Insulating joints on the rails are key components of the railway track circuit system. Their core function is to separate adjacent track circuit sections, prevent current from flowing between sections, and ensure that the track circuit can accurately detect train positions and achieve automatic signal control. Warning markers are usually placed in the middle of two merging tracks at a distance of 4 meters. If the distance between the tracks is less than 4 meters, they are placed at the starting point of the maximum distance between the centerlines of the two tracks, and the distance between the rail corresponding to the warning marker and the insulating joint must not be less than 3.5 meters.

[0003] Currently, operators use a measuring tape to measure and locate the position of the warning marker, but there is a lack of a specialized tool for measuring the position of the warning marker. Summary of the Invention

The radial inner wall of the rotating cavity is provided with a plurality of first grooves spaced apart. When the adjusting member drives the ranging element to rotate and adjust the angle, the ball falls into the first groove.

[0011] In one embodiment, the first measuring unit further includes two storage mechanisms corresponding to the two folding arms. The storage mechanism is used to adjust the angle between the folding arm and the mounting part.

[0041] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] See appendix Figure 1 - Appendix Figure 2 , attached Figure 1 - Appendix Figure 2 This application shows a schematic diagram of the overall three-dimensional structure of a warning marker measuring device according to an embodiment of the present application, used to measure the position of the warning marker relative to two merging lines, including:

[0048] The first measuring unit 100 includes two folding arms 110 rotatably connected, and the two folding arms 110 are correspondingly arranged with two tracks; in the corresponding folding arms 110 and tracks, the folding arms 110 are used to measure the vertical distance between the warning marker and the track rail.

[0049] The second measuring unit 200 includes two ranging elements 220 corresponding to the two folding arms 110. Among the corresponding folding arms 110 and ranging elements 220, the ranging elements 220 are located at the ends of the folding arms 110 near the line. The ranging elements 220 are used to measure the distance along the line between the warning marker and the insulating joint.

[0050] This application presents an integrated design, comprising a first measuring unit 100 and a second measuring unit 200, used to simultaneously verify the compliance of the warning marker position and measure the distance between the warning marker and the insulating joint, meeting the accuracy and efficiency requirements of railway field operations. The first measuring unit 100 includes two rotatably connected folding arms 110, corresponding one-to-one with the two merging tracks. The folding arms 110 are hinged, adaptable to different track spacings, such as a standard 4m track spacing or special sections less than 4m. Through the physical contact between the folding arms 110 and the inner side of the rail, the vertical distance between the warning marker and the track rail is measured, ensuring that the warning marker is in a standard position 2m perpendicular to the center of each of the two tracks.

[0051] The second measuring unit 200 includes two distance measuring elements 220, used to measure the straight-line distance between the warning marker and the insulating joint along the line direction, directly verifying whether the safety specification requirement of ≥3.5m is met. This device integrates the two key links of position calibration and distance measurement, eliminating the need for separate positioning tools such as tape measures, right-angle rulers, and distance measuring tools, reducing on-site operation steps. A single device can complete the entire process, reducing operation time by more than 50%.

[0052] During measurement, first confirm the correct location of the on-site warning marker. If the on-site warning marker is located inside the area where a warning marker should be installed, test the distance between the rail and the insulated joint corresponding to the intended warning marker, and notify the track maintenance section to relocate the warning marker, ensuring that the distance between the rail and the insulated joint corresponding to the relocated warning marker is not less than 3.5 meters. If the on-site warning marker is located outside the area where a warning marker should be installed, test the distance between the rail and the insulated joint corresponding to the on-site warning marker. If the measured distance is not less than 3.5 meters, measure the distance between the rail and the insulated joint corresponding to the intended warning marker again. If the measured distance meets the specified value, contact the track maintenance section to relocate the warning marker.

[0053] See appendix Figure 4 - Appendix Figure 8 The second measuring unit 200 also includes a mounting part 210 and an adjusting member 230. The mounting part 210 has a mounting cavity 211, and the adjusting member 230 is rotatably disposed in the mounting cavity 211. The ranging element 220 is detachably mounted on the adjusting member 230. The adjusting member 230 is used to adjust the angle of the ranging element 220.

[0054] In some embodiments, the mounting part 210 serves as the base carrier of the second measuring part 200 and is rotatably connected to the end of the folding arm 110. An mounting cavity 211 is provided inside the mounting part to accommodate the adjustment member 230 and part of the ranging element 220, which protects the internal components and ensures the compactness of the overall structure.

[0055] In some embodiments, the adjusting member 230 is rotatably disposed within the mounting cavity 211, and the ranging element 220 is detachably mounted on the adjusting member 230. The adjusting member 230 is adapted to different angle adjustment requirements. The ranging element 220 is linked with the adjusting member 230, and its measuring angle is changed by the rotation of the adjusting member 230, thereby achieving accurate distance measurement along the line direction.

[0056] In some embodiments, during actual operation, the insulating joint may form a slight angle with the location of the warning marker due to factors such as the rail laying angle and the turnout position, and is not completely parallel to the track. The adjusting component 230 can drive the ranging element 220 to rotate, so that the ranging direction is completely aligned with the line connecting the insulating joint and the warning marker, avoiding ranging errors caused by angular deviation.

[0057] In some embodiments, if a laser ranging element is selected, it must be ensured that the laser beam is accurately pointed at the measuring point of the insulating joint. If an infrared ranging element is selected, the receiving angle must be adjusted to avoid environmental interference. The detachable design of the adjusting element 230 allows for flexible replacement of different types of ranging elements, and the optimal working angle can be matched by angle adjustment.

[0058] In some embodiments, if the ranging element 220 malfunctions, such as a damaged laser module or a depleted battery, it can be quickly disassembled and replaced without completely disassembling the second measuring unit 200, reducing maintenance costs and downtime. Different types and levels of ranging elements can be used to meet operational needs, improving the device's versatility.

[0059] In some embodiments, the ranging element 220 is fixed to the adjusting member 230 via a detachable structure to ensure a secure connection. Depending on the location of the insulating joint on site, the adjusting member 230 is rotated to adjust the angle of the ranging element 220, ensuring the ranging direction accurately points to the measuring point on the insulating joint, such as the signal reflector at the connection between the insulating joint and the rail. The ranging element 220 is then activated to obtain the distance along the track from the rail position corresponding to the warning marker to the insulating joint.

[0060] See appendix Figure 7 - Appendix Figure 8 The adjusting component 230 includes a rotating seat 231 and a slide rail 232. A rotating cavity 212 is provided on the inner wall of the mounting cavity 211, and the rotating seat 231 is located in the rotating cavity 212. The adjusting component 230 is rotatably disposed in the rotating cavity 212 via the rotating seat 231. A slide seat 221 is provided on the side of the ranging element 220 facing the adjusting component 230, and the adjusting component 230 is slidably disposed on the slide rail 232 via the slide seat 221.

[0061] In some embodiments, a rotating cavity 212 is formed in the inner wall of the mounting cavity 211 of the mounting part 210, and the rotating seat 231 is embedded in the rotating cavity 212 to achieve rotation of 360° or a specific angle range. Its function is to drive the entire ranging element 220 to deflect at an angle, matching the spatial angle between the insulating joint and the warning marker. The rotating cavity 212 provides a limit and support for the rotating seat 231, preventing offset or jamming during rotation and ensuring the stability of angle adjustment.

[0062] In some embodiments, the slide rail 232 is fixed on the rotating base 231, and the slide base 221 of the ranging element 220 is adapted to the slide rail 232, enabling the ranging element 220 to slide linearly along the slide rail 232. This allows for fine-tuning of the ranging element 220's position or quick replacement. If the measuring point still deviates after adjusting the angle of the rotating base 231, further calibration can be performed by sliding the slide rail 232, improving measurement accuracy.

[0063] In some embodiments, a slide block 221 is provided on the side of the ranging element 220 facing the adjusting member 230. The slide block 221 and the slide rail 232 are detachably slidably engaged, including but not limited to the dovetail slide rail 232, a snap-fit ​​fixing mechanism, a guide rail, and a locking bolt. By unlocking the snap-fit ​​or the bolt, the ranging element 220 can be quickly removed for easy replacement, charging, or maintenance. After sliding into position, the slide block 221 can be fixed by a locking structure to prevent the ranging element 220 from shifting during measurement and to ensure data stability.

[0064] In some embodiments, the rotating base 231 is embedded in the rotating cavity 212, and the slide rail 232 is integrated on the rotating base 231. All adjustment structures are housed within the mounting cavity 211, preventing exposed parts from being corroded by dust and rainwater. This also reduces the size of the device, making it easy to carry and operate, especially in narrow switch areas. If the laser ranging module runs out of power, simply unlock the slide base 221, replace it with the corrected sliding calibration position, and lock it to continue operation.

[0065] In some embodiments, an angle scale is added at the mating point between the rotating seat 231 and the mounting part 210 to facilitate operators to accurately record and reproduce the adjustment angle; limit blocks are added at both ends of the slide rail 232 to prevent the slide seat 221 from sliding excessively and causing the ranging element 220 to fall off.

[0066] See appendix Figure 7 - Appendix Figure 8 The radial outer wall of the rotating seat 231 is provided with a plurality of slots 233 at intervals. A first elastic element 234 and a ball 235 are provided in the slots 233. The ball 235 is located on the side of the first elastic element 234 away from the bottom wall of the slot 233. The radial inner wall of the rotating cavity 212 is provided with a plurality of first grooves 213 at intervals. When the adjusting element 230 drives the ranging element 220 to rotate and adjust the angle, the ball 235 falls into the first groove 213.

[0067] In some embodiments, the radial outer wall of the rotating seat 231 is provided with a plurality of slots 233 at intervals, the depth of which is adapted to the combined height of the first elastic member 234 and the ball 235. The first elastic member 234, such as a compression spring or sheet, and the ball 235 are installed sequentially in each slot 233. The ball 235 is located on the side of the elastic member away from the bottom wall of the slot 233. In its natural state, the elastic member will push the ball 235 outward, so that part of the ball 235 is exposed on the outer wall of the rotating seat 231.

[0068] In some embodiments, the number of slots 233 is typically the same as the number of first grooves 213 on the inner wall of the rotating cavity 212 and is evenly distributed to ensure uniformity of angle adjustment. A plurality of first grooves 213 are spaced apart on the radial inner wall of the rotating cavity 212 corresponding to the positions of the slots 233. The depth of each first groove 213 is slightly less than the radius of the ball 235, and its width is adapted to the diameter of the ball 235. The first grooves 213 are arc-shaped and fit against the surface of the ball 235 to form a snap-fit ​​positioning structure.

[0069] In some embodiments, when the adjusting member 230 is rotated, the ball 235 is squeezed by the inner wall of the rotating cavity 212, retracting into the slot 233 and compressing the first elastic member 234. When the rotating seat 231 rotates until the slot 233 aligns with the first groove 213, the elastic force of the first elastic member 234 is released, pushing the ball 235 into the first groove 213, creating a locking sensation and achieving precise positioning of the rotation angle. When unlocking, if the rotational torque continues to be applied, the ball 235 can overcome the elastic force of the elastic member and disengage from the first groove 213, continuing to rotate to the next groove position, completing the angle switching.

[0070] In some embodiments, the diameter of the ball 235 is larger than the opening width of the slot 233 to prevent the ball 235 from falling out of the slot 233, allowing it to be partially exposed on the outer wall of the rotating seat 231. The elastic force of the first elastic member 234 is matched such that the elastic force is sufficient to support the ball 235 to be inserted into the groove for positioning, while also being able to be overcome by the manual rotation torque, thus balancing positioning stability and ease of adjustment.

[0071] In some embodiments, the first groove 213 corresponds to the slot 233, and each first groove 213 corresponds to a preset adjustment angle, such as a positioning point every 15°, to meet common angle adjustment needs on site.

[0072] In some embodiments, the snap-fit ​​structure between the ball bearing 235 and the groove can fix the rotation angle of the rotating seat 231, preventing the angular deviation of the ranging element 220 due to vibration or contact during measurement, ensuring that the measurement direction is always aligned with the measuring point of the insulating joint, and improving data accuracy. The snap-fit ​​feedback when the ball bearing 235 is inserted into the groove allows operators to perceive that the angle adjustment is in place without additional scale markings, which is especially suitable for low-light or fast-paced operation scenarios, reducing the operational threshold. The mechanical positioning method of the ball bearing 235 and the groove has no electronic components and is highly resistant to dust and rain corrosion. The first elastic element 234 uses a corrosion-resistant spring, such as a stainless steel spring, which can adapt to the harsh working conditions of railway sites and extend the service life of the device.

[0073] See appendix Figure 2 - Appendix Figure 4 Appendix Figure 9 - Appendix Figure 10 The first measuring unit 100 also includes two storage mechanisms 120 corresponding to the two folding arms 110. The storage mechanism 120 is used to adjust the angle between the folding arm 110 and the mounting part 210.

[0074] In some embodiments, the storage mechanism 120 and the folding arm 110 are arranged in a one-to-one correspondence and can be used for angle adjustment. The angle between the folding arm 110 and the mounting part 210 (i.e., the carrier of the second measuring part 200) is adjusted so that the folding arm 110 can fit against the inner side of rails with different line spacings and rail types, adapting to the measurement needs of complex lines such as straight sections and curved sections. In the non-operating state, the mounting part 210 can be folded up to a position parallel to the folding arm 110, reducing the overall size of the device and facilitating carrying and storage.

[0075] In some embodiments, during operation, the angle between the folding arm 110 and the mounting portion 210 is adjusted by the storage mechanism 120 so that the end of the folding arm 110 fits against the inner side of the rail, thus completing the calibration of the warning marker position. When storing, the angle locking component is unlocked, and the mounting portion 210 is folded up to be parallel to the folding arm 110, reducing the space occupied by the device.

[0076] See appendix Figure 2 - Appendix Figure 3 Appendix Figure 9 - Appendix Figure 10 The storage mechanism 120 includes a first swing member 121 and a second swing member 122. The first swing member 121 is connected to the folding arm 110, and the second swing member 122 is connected to the mounting part 210. A first rotating shaft 1212 is provided at one end of the first swing member 121 near the second swing member 122, and the second swing member 122 is rotatably connected to the first swing member 121 through the first rotating shaft 1212.

[0077] In some embodiments, one end of the first swing member 121 is fixedly connected to the folding arm 110, such as by bolting, welding, or integral molding, and the other end extends to the second swing member 122, where a first pivot 1212 is provided. One end of the second swing member 122 is fixedly connected to the mounting portion 210, which can be fixed by bolts or slots to ensure connection stability, and the other end is hinged to the first swing member 121 via the first pivot 1212 to form a rotatable joint structure.

[0078] In some embodiments, the rotation angle range of the first swing member 121 and the second swing member 122 about the first rotating shaft 1212 is typically designed to be 0°-90°. 0° represents the retracted state, where the folding arm 110 is parallel to the mounting portion 210. 90° represents the operating state, where the folding arm 110 is perpendicular to the mounting portion 210.

[0079] In some embodiments, by rotating the first swing member 121, the folding arm 110 is driven to form the required angle between the folding arm 110 and the mounting part 210, thus completing the angle matching for the calibration of the warning marker position. When switching to the storage state, the first swing member 121 is rotated in the opposite direction to fold the folding arm 110 until it is parallel to the mounting part 210, reducing the overall size of the device and making it easier to carry and store. The first rotating shaft 1212 serves as the core fulcrum, with a simple structure and smooth rotation, avoiding jamming and adapting to frequent unfolding and storage operations on site.

[0080] See appendix Figure 2 - Appendix Figure 4 The storage mechanism 120 also includes a locking member 123 and a linkage member 124; the linkage member 124 is used to support the second swing member 122; the locking member 123 is used to lock the linkage member 124; when the locking member 123 locks the linkage member 124, the second swing member 122 is locked relative to the first swing member 121.

[0081] In some embodiments, one end of the linkage 124 is hinged to the first swing member 121, and the other end is hinged to the second swing member 122, forming a triangular support structure, i.e., the first swing member 121, the second swing member 122, and the linkage 124 form a triangle. Its core function is to support the second swing member 122 and the mounting part 210 through the stability of the triangle, restrict the relative rotation of the first and second swing members 122, and fix the included angle between the folding arm 110 and the mounting part 210.

[0082] When the folding arm 110 is adjusted to the target angle, the linkage 124 rotates synchronously with the swinging component to the corresponding position, forming a rigid support to counteract external vibrations or contact forces during the measurement process.

[0083] In some embodiments, the locking member 123 is mounted on the first swing member 121, near the hinge point of the linkage member 124. Its function is to lock the position of the linkage member 124, prevent the linkage member 124 from rotating and causing the triangular support structure to fail, and ultimately achieve relative locking of the first and second swing members 122.

[0084] In some embodiments, rotating the folding arm 110 causes the first swing member 121 to rotate around the first pivot 1212, and the linkage member 124 rotates synchronously with the swing member until the folding arm 110 reaches the target angle, such as 90°, to fit against the rail. After the angle of the folding arm 110 is determined, the locking member 123 is operated to lock the position of the linkage member 124. At this time, the linkage member 124 and the first and second swing members 122 form a stable triangular structure, restricting the relative rotation of the swing members, and the angle of the folding arm 110 is fixed.

[0085] In some embodiments, during the storage phase, the locking member 123 is first unlocked, the folding arm 110 is rotated in the opposite direction, and the linkage member 124 retracts with the swing member until the folding arm 110 is parallel to the mounting part 210, thus completing the storage.

[0086] See appendix Figure 2 - Appendix Figure 3 The linkage 124 includes a second rotating shaft 1241, a third rotating shaft 1242, and a linkage plate 1243. The linkage plate 1243 is used to connect the second rotating shaft 1241 and the third rotating shaft 1242. The second rotating shaft 1241 is disposed on the second swing member 122. The first swing member 121 has a sliding groove 1213. The third rotating shaft 1242 is slidably disposed in the sliding groove 1213. When the linkage 124 slides back and forth relative to the sliding groove 1213 through the third rotating shaft 1242, the angle between the second swing member 122 and the first swing member 121 changes accordingly.

[0087] In some embodiments, the linkage plate 1243 serves as the main body of the linkage member 124, with its two ends connected to the second rotating shaft 1241 and the third rotating shaft 1242 respectively, forming a rigid connecting rod that transmits motion and support force. The second rotating shaft 1241 is fixed on the second swing member 122, and the linkage plate 1243 can rotate around the second rotating shaft 1241, forming a swing pair. The third rotating shaft 1242 is installed at the other end of the linkage plate 1243 and is embedded in the groove 1213 of the first swing member 121, forming a sliding swing pair. The groove 1213 is an elongated groove formed on the first swing member 121, typically arranged along the length of the first swing member 121, providing a sliding trajectory for the third rotating shaft 1242 and restricting its direction of movement.

[0088] In some embodiments, the linkage 124 achieves angular changes in the first and second swing members 122 through a combination of sliding and oscillating motions. Initially, the third rotating shaft 1242 is located at one end of the slide groove 1213, i.e., away from the first rotating shaft 1212. The linkage plate 1243 is folded between the first and second swing members 122, with an included angle of 0° between them. During adjustment, rotating the folding arm 110 causes the first swing member 121 to rotate around the first rotating shaft 1212, while the third rotating shaft 1242 slides along the slide groove 1213 to the other end. Simultaneously, the linkage plate 1243 oscillates around the second rotating shaft 1241. As the third rotating shaft 1242 slides, the included angle between the first and second swing members 122 gradually increases to 90°.

[0089] In some embodiments, after adjustment, the linkage plate 1243 forms a triangular structure with the first and second swing members 122. The limiting effect of the slide groove 1213 on the third rotating shaft 1242 further enhances the structural rigidity, effectively resisting external forces such as vibration and contact during measurement, preventing the folding arm 110 from shifting angle, and ensuring measurement accuracy. In the stored state, the linkage plate 1243 can be completely folded between the first and second swing members 122, and the third rotating shaft 1242 slides to the end of the slide groove 1213 without increasing the size of the device, maintaining portability.

[0090] See appendix Figure 5 The locking component 123 includes a mounting shaft 1231, a locking body 1232, and a second elastic member 1235. The mounting shaft 1231 is fixedly mounted on the first swing member 121. The locking body 1232 has a slot 1234, and the mounting shaft 1231 is inserted into the slot 1234. The second elastic member 1235 is sleeved on the outside of the mounting shaft 1231, and both ends of the second elastic member 1235 are respectively connected to the mounting shaft 1231 and the inner wall of the slot 1234. The locking body 1232 has a limiting part 1233 at one end facing the third rotating shaft 1242, and the limiting part 1233 is used to lock the third rotating shaft 1242.

[0091] In some embodiments, the mounting shaft 1231 is fixed to the first swing member 121, such as by welding or bolting, serving as a fixing fulcrum for the locking member 123, with its axial direction perpendicular to the working plane of the first swing member 121. The locking body 1232 is sleeved on the mounting shaft 1231 through the slot 1234, and can rotate around the mounting shaft 1231. One end facing the third rotating shaft 1242 is provided with an arc-shaped notch-shaped limiting part 1233, and the curvature matches the outer diameter of the third rotating shaft 1242 to achieve precise engagement.

[0092] In some embodiments, the second elastic element 1235 is a torsion spring, sleeved on the outside of the mounting shaft 1231, with its two ends connected to the mounting shaft 1231 and the inner wall of the slot 1234, respectively. Under normal conditions, it provides a preload torque to the locking body 1232, keeping the limiting part 1233 facing the slide groove 1213. The slot 1234 is a through hole formed on the locking body 1232, with a diameter slightly larger than the diameter of the mounting shaft 1231, ensuring that the locking body 1232 can rotate flexibly, while simultaneously achieving reset through the torsion spring.

[0093] In some embodiments, in the unlocked state, the locking body 1232 is manually moved to rotate around the mounting shaft 1231. The torsion spring is twisted and stores force, and the limiting part 1233 moves away from the slide groove 1213. At this time, the third rotating shaft 1242 can slide freely along the slide groove 1213, driving the folding arm 110 to adjust its angle. In the locked state, when the third rotating shaft 1242 slides to the target position, the locking body 1232 is released. The rebound force of the torsion spring causes the locking body 1232 to rotate in the opposite direction, and the arc-shaped notch of the limiting part 1233 precisely engages with the outer wall of the third rotating shaft 1242. The fitting structure between the arc-shaped notch and the third rotating shaft 1242 restricts the sliding and rotation of the third rotating shaft 1242, thereby locking the position of the linkage 124 and fixing the included angle of the first and second swinging parts 122.

[0094] In some embodiments, the locking body 1232 is automatically reset by the preload of the torsion spring, without the need for additional bolt tightening or buckle engagement. Unlocking / locking can be completed simply by manually moving the lever, greatly improving on-site work efficiency.

[0095] See appendix Figure 9 - Appendix Figure 10 The mounting part 210 is provided with a roller 214 facing the direction of gravity, and the roller 214 is used to abut against the rail head; the first swing member 121 is also provided with a second groove 1211, which is used to accommodate the second rotating shaft 1241; the first measuring part 100 also includes a hinge 112, and the two folding arms 110 are rotatably connected by the hinge 112; the folding arm 110 is also provided with a levelness measuring element 111; the second elastic member 1235 is configured as a torsion spring.

[0096] In some embodiments, the roller 214 is located on the side of the mounting portion 210 facing the direction of gravity and is adapted to the rail head. The roller 214 provides a stable support point for the device, preventing the device from tilting or sliding during measurement. Furthermore, the roller 214 is rollable, facilitating movement of the device along the rail and quick switching of measurement positions. The outer diameter of the roller 214 matches the curvature of the rail head, ensuring a tight fit, which is particularly suitable for the rail head profile of standard gauge 1435mm rails, improving the stability of the device on the rail.

[0097] In some embodiments, the second groove 1211 is used to accommodate the second pivot 1241. When the folding arm 110 is retracted, the second pivot 1241 is embedded in the groove to avoid scratches or structural interference caused by the pivot being exposed, so that the first and second swing members 122 can fit together completely, further reducing the storage volume.

[0098] In some embodiments, the hinge 112 enables the rotatable connection of the two folding arms 110, allowing the device to adapt to different line spacings. When unfolded, the two folding arms 110 can adjust their included angle via the hinge 112, respectively fitting against the inner sides of the rails of the two converging lines. When folded, the two folding arms 110 can be folded in half via the hinge 112, further shortening the overall length of the device.

[0099] In some embodiments, the levelness measuring element 111 is mounted on the surface of the folding arm 110, and can be a bubble level, electronic inclinometer, etc. It can monitor the levelness of the folding arm 110 in real time, ensuring that the folding arm 110 is perpendicular to the inside of the rail, avoiding measurement errors caused by device tilt. The electronic inclinometer can directly display angle values, facilitating accurate calibration, and is particularly suitable for measuring curved or sloping sections. Operators can quickly adjust the device's posture by observing the levelness element, eliminating the need for an additional level, thus improving measurement efficiency.

[0100] In some embodiments, the standard track gauge is 1435mm, and the warning marker needs to be set at a position 2m perpendicular to the center line of each of the two tracks, that is, the vertical distance from the warning marker to the center line of each track is 2m (2000mm). The distance from the center line of the track to the inside of the rail is half the track gauge: 1435mm ÷ 2 = 717.5mm. Therefore, the vertical distance from the warning marker to the inside of the rail = 2000mm - 717.5mm = 1282.5mm. This value directly determines the length of the roller 214 to the hinge 112. The roller 214 fits against the inside of the rail, and the hinge 112 corresponds to the position of the warning marker. The lengths of the two must be precisely matched at 1282.5mm to ensure rapid calibration of the warning marker position.

[0101] In some embodiments, within a railway track circuit system, the rails serve as the conductive medium for transmitting the detection current of the track circuit. If the metal components of the warning marker measuring device directly contact the rails, a current path may be created, leading to a short circuit in the track circuit. The core function of adding an insulating pad is electrical isolation, blocking the conductive connection between the warning marker measuring device and the rails. This ensures both physical contact between the device and the rails and prevents short circuits in the track circuit, ensuring that the measurement operation does not interfere with the normal operation of the railway.

[0102] An insulating pad is installed at the connection between the roller 214 and the mounting part 210 to isolate the conductive path between the roller 214 and the mounting part 210. Insulating pads are also required in areas where the bottom of the device may come into contact with the rail, such as the bottom surface of the mounting part 210 and the outside of the folding arm 110, to prevent accidental contact between metal parts and the rail.

[0103] 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.

[0104] The above embodiments merely illustrate 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.
