Description

Technical Field

[0001] This application relates to the technical field of railway surveying, and particularly to a railway gauge measuring device. Background Art

[0002] The change of railway gauge has a significant impact on the operation of high-speed trains. The gauge, that is, the distance between the two rails of the track, plays a crucial role in the stability and safety of train operation. Under the influence of the impact of EMU operation, geological movement, regional ground settlement, and construction of adjacent lines, etc., the high-speed railway line may have minor changes such as settlement and distortion. These changes need to be accurately monitored to ensure the high-speed and stable operation of the EMU. At the same time, temperature deformation is also an important factor affecting the gauge. The steel rail will expand and contract thermally under the influence of temperature changes, resulting in an increase or decrease in the gauge, which may cause derailment or unstable train operation when the train passes. Therefore, any change in the steel rail gauge may affect the operation safety and stability of the high-speed railway, so it is necessary to ensure the smoothness and safety of the railway line through high-precision monitoring and maintenance.

[0003] The existing gauge measurement method is contact measurement, which requires manual use of a gauge to measure each key point on the section to be measured one by one, and manual reading of the values on the detection device. The detection efficiency is low, the accuracy is insufficient, and it is greatly affected by human factors. Utility Model Content

[0005] An embodiment of this application provides a railway gauge measuring device, including a positioning rod, a positioning module and a gauge module respectively arranged at both ends of the positioning rod, and a gauge data processing module communicatively connected to the gauge module;

[0006] The positioning module includes a positioning block. One side surface of the positioning block is a first abutting surface, and the positioning module is used to be placed on one of the two steel rails in the railway. The first abutting surface of the positioning block is used to abut against the working edge of the steel rail;

[0007] The gauge module includes a sliding positioning block and a laser displacement sensor. The sliding direction of the sliding positioning block is the same as the length direction of the positioning rod. One side surface of the sliding positioning block is a second abutting surface, and the gauge module is used to be placed on the other one of the two steel rails in the railway. The sliding positioning block is used to slide so that the second abutting surface abuts against the working edge of the other steel rail.

[0026] With the above technical solution, the second positioning portion in both the storage state and the extended state can be abutted by the ball plungers, thereby improving the state stability of the second positioning portion.

[0027] In some embodiments, the gauge module includes a battery assembly, a radio frequency module, and a radio frequency antenna. The battery assembly is connected to the laser displacement sensor, the radio frequency module, and the radio frequency antenna. The radio frequency module is connected to the laser displacement sensor and communicates with the gauge data processing module through the radio frequency antenna.

[0052] To make the purpose, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0053] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of an embodiment of the present application.

[0054] An embodiment of the present application provides a railway gauge measuring device, which includes a positioning rod 3, a positioning module 2 and a gauge module 1 respectively arranged at both ends of the positioning rod 3, and a gauge data processing module communicatively connected to the gauge module 1. This device can meet the measurement range of the rail gauge of 1435 [-25, 35] mm, and has the characteristics of high efficiency and high precision.

[0055] The positioning module 2 includes a positioning block. One side surface of the positioning block is a first abutting surface, and the positioning module 2 is used to be placed on one of the two rails in the railway. The first abutting surface of the positioning block is used to abut against the working edge of the rail.

[0056] The gauge module 1 includes a sliding positioning block 10 and a laser displacement sensor 20. The sliding direction of the sliding positioning block 10 is the same as the length direction of the positioning rod 3. One side surface of the sliding positioning block 10 is a second abutting surface 101, and the gauge module 1 is used to be placed on the other of the two rails in the railway. The sliding positioning block 10 is used to slide so that the second abutting surface 101 abuts against the working edge of the other rail, and the laser displacement sensor 20 is used to measure the sliding distance of the sliding positioning block 10.

[0057] The gauge data processing module is communicatively connected to the laser displacement sensor 20, and is used to obtain the sliding distance, and determine the gauge in combination with the lengths of the positioning module 2 and the positioning rod 3. It can be understood that the gauge data processing module can be set separately, and during measurement, it can be inserted into a measurement computer through an interface to realize data display, etc.; the gauge data processing module can also be integrated into the rail maintenance system in the form of a software program, thereby improving the measurement convenience.

[0058] This device realizes non-contact measurement through the laser displacement sensor 20, improves the measurement efficiency and measurement accuracy, and is convenient for measurement.

[0059] At the same time, this device provides a basis for gauge measurement through the total length L of the positioning module 2 and the positioning rod 3 whose length distance can be determined. Then, through the lateral sliding △X of the sliding positioning block 10 on the adapted rail, the actual deviation is measured by laser, and the gauge is determined, that is, L±△X. The laser measurement distance is controlled, so that the performance requirements of the laser displacement sensor 20 can be controlled, thereby reducing costs, and enabling the laser working environment to be controlled in the gauge module 1, reducing the influence of the external environment, and thus improving the measurement accuracy.

[0060] It can be understood that the total length L of the positioning module 2 and the positioning rod 3 refers to the distance from the measurement starting point of the positioning module 2 to the connection point of the positioning rod 3 and the gauge module 1. The specific calculation method of the lateral sliding △X and L can be determined by the fixed distance between the laser displacement sensor 20 and this connection point.

[0061] Moreover, by adopting the positioning rod 3 and positioning modules 2 and gauge modules 1 arranged at both ends, the device achieves precise positioning of two steel rails in the railway, ensures the accuracy of the measurement reference, and thus improves the measurement accuracy.

[0062] In one embodiment, there are two positioning blocks, and the first abutting surfaces of the two positioning blocks are both used to abut against the working edge of the steel rail, that is, the inner side surface of the steel rail.

[0063] In one embodiment, there are two sliding positioning blocks 10. The two sliding positioning blocks 10 can slide synchronously, and the second abutting surfaces 101 of the two sliding positioning blocks 10 are both used to abut against the working edge of the other steel rail.

[0064] In the above two ways, by determining a straight line through two points, the parallel setting of the positioning module 2 or the gauge module 1 relative to the corresponding steel rail is realized, that is, the parallelism between the device and the steel rail is ensured along the longitudinal direction of the steel rail, ensuring the measurement reference, and thus further improving the measurement accuracy.

[0065] Preferably, both the positioning block and the sliding positioning block 10 abut and cover at least 16 mm downward from the rail top of the working edge of the steel rail, so as to ensure the abutting stability and reliability.

[0066] Please refer to Figure 2 and Figure 3 , Figure 2 which is the schematic cross-sectional structure diagram of the gauge module 1 in the embodiment of the present application after being installed on the positioning rod 3; Figure 3 which is the schematic structure diagram of the gauge module 1 in the embodiment of the present application.

[0067] In one embodiment, the gauge module 1 includes a slide rail mechanism 30 extending in the same direction as the positioning rod 3, and the sliding positioning block 10 is connected to the slider 31 of the slide rail mechanism 30.

[0068] The slide rail mechanism 30 further includes a slide rail 32 and a guide rod 33 arranged in the same direction. The slider 31 is slidably connected to the slide rail 32. An elastic member 34, such as a return spring, is sleeved on the guide rod 33, and the elastic member 34 exerts a driving force on the slider 31, so that the slider 31 drives the sliding positioning block 10 to slide, so that the second abutting surface 101 abuts against the working edge of the other steel rail.

[0069] The slider 31 has a measurement surface 310 facing the laser displacement sensor 20 to measure the sliding distance.

[0070] This method realizes that the slider 31 drives the sliding positioning block 10 to adapt to the steel rail through the slide rail mechanism 30 and the elastic member 34, without manual sliding, further improving the measurement efficiency and measurement accuracy, and can also realize continuous automatic measurement along the longitudinal direction of the steel rail, greatly improving the measurement efficiency.

[0071] In one embodiment, the slider 31 has an extension plate 311, which extends away from the pushing direction of the elastic member 34, and the measuring surface 310 is located at the end of the extension plate 311. The extension plate 311 expands the distance between the measuring surface 310 and the laser displacement sensor 20, so that under different track gauges, the laser displacement sensor 20 can be within the optimal working range, thereby further improving the measurement accuracy.

[0072] In one embodiment, a positioning pin 40 is provided at the bottom of the gauge module 1 .

[0073] See Figure 4 , Figure 4 Schematic diagram of the structure of the connecting member 50 of the positioning rod 3 in the embodiment of the present application.

[0075] In this method, the gauge module 1 and the positioning rod 3 are detachably connected via the connector 50, thereby facilitating the transport of the device and improving measurement convenience. Furthermore, the coordination of the limiting slot 51 and the positioning hole 52 improves the accuracy of the connection and positioning of the connector 50 between the gauge module 1 and the positioning rod 3, thereby ensuring the accuracy of the total length of the positioning module 2 and the positioning rod 3 in the gauge data and ensuring measurement accuracy.

[0076] In one embodiment, the sliding positioning block 10 includes a first positioning portion 11 and a second positioning portion 12 that are rotatably connected. The first positioning portion 11 has an accommodating cavity, and the second positioning portion 12 can be rotatably embedded in the first positioning portion 11 .

[0077] The second abutting surface 101 is a side surface of the first positioning portion 11 and / or the second positioning portion 12 .

[0078] This method forms a sliding positioning block 10 through the rotational connection of the first positioning part 11 and the second positioning part 12, taking into account the convenience of storage and practicality of the sliding positioning block 10, and the larger abutment area can improve the stability and accuracy of the gauge module 1 on the corresponding rail, thereby improving the measurement accuracy.

[0079] In one embodiment, the first positioning portion 11 is provided with at least two ball plungers 13, and the positioning ends of the at least two ball plungers extend into the accommodating cavity, and are respectively used to abut the second positioning portion 12 when the second positioning portion 12 is embedded in the accommodating cavity, and when the second positioning portion 12 is flipped and extended out of the accommodating cavity, so that the second positioning portion 12 can be abutted by the ball plunger 13 regardless of whether it is in the retracted or extended state, that is, self-locking is achieved, thereby improving the state stability of the second positioning portion 12.

[0080] In one embodiment, the gauge module 1 includes a battery assembly 21, a radio frequency module 22, and a radio frequency antenna 23. The battery assembly 21 is connected to the laser displacement sensor 20, the radio frequency module 22, and the radio frequency antenna 23. The radio frequency module 22 is connected to the laser displacement sensor 20 and is communicatively connected to the gauge data processing module through the radio frequency antenna 23.

[0081] This method realizes power supply to the module without external cables by the built-in battery assembly 21, and realizes wireless communication through the radio frequency module 22 and the radio frequency antenna 23. That is, the wireless use of the gauge module 1 is realized through the battery assembly 21, the radio frequency module 22, and the radio frequency antenna 23, further improving the measurement convenience.

[0082] Preferably, the battery assembly 21 is a 12V lithium battery with battery parameters of 12V DC voltage and a capacity of 1050 mah, which can meet the 10-hour battery life of the gauge module 1.

[0083] In one embodiment, the gauge module 1 includes a housing 60. The sliding positioning block 10 protrudes from the housing 60, and the laser displacement sensor 20 is disposed inside the housing 60. The housing 60 is made of nylon material. By using the nylon material housing 60, the weight of the gauge module 1 can be controlled while ensuring the strength, thereby improving the convenience of transportation and carrying.

[0084] Preferably, the housing 60 adopts a high-strength nylon 3D printing structure design, which has a small density, high strength, and corrosion resistance, ensuring both the overall aesthetics and the overall strength of the device.

[0085] In one embodiment, the device is provided with a button switch 61, a charging port 62, and a power display screen 63 on the housing 60 for instrument operation. The interfaces are embedded on the top and rear of the instrument, ensuring the aesthetic appearance of the instrument without affecting the overall function. The instrument integrates a lithium battery inside, and the device can be turned on and off through the main switch.

[0086] The function interfaces of the instrument panel are designed to be hidden. For example, the WiFi antenna is embedded in the detection module without affecting the function and is flush with the gauge detection module. The radio frequency antenna 23 mainly enhances the radio frequency transmission and reception signals. The power display, the charging port 62, and the button switch 61 are flush with the module.

[0087] In one embodiment, the positioning module 2 is a rail profile measuring instrument, and the positioning block is the positioning block of the rail profile measuring instrument. By replacing the positioning module 2 with an existing rail profile measuring instrument in this way, the cost of the device can be reduced. At the same time, the device is used in cooperation with the rail profile measuring instrument, making the function more convenient. Multiple track parameters can be obtained in a single measurement, and the efficiency is greatly improved, which is convenient for wheel-rail matching analysis and can greatly meet the long-term tracking of rail conditions such as gauge, rail head profile, rail profile quality, and rail wear in the field of railway track maintenance.
