[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3This utility model provides a technical solution: an online measuring device for a train coupler, comprising an online measuring device body 1 and a train coupler 8. The online measuring device body 1 is located above the train coupler 8. A mounting base 2 is provided on the online measuring device body 1 and welded to the outside of the train car. A limiting member 201 is integrally provided on the mounting base 2. The limiting member 201 has an L-shaped structure and at least four evenly spaced mounting holes 202. This structure, through the integral forming of the mounting base 2, ensures the stability of the limiting member 201 relative to the train structure, providing a reliable positioning structure for the installation of the online measuring device body 1. Simultaneously, the mounting base 2 is a fixed structure, and the positioning base 3 can be easily disassembled and assembled, facilitating the online measuring device body 1. The positioning device is designed for inspection and maintenance. A U-shaped positioning seat 3 is snapped onto the limiting component 201, and a support plate 303 is fixed within the U-shaped structure of the positioning seat 3. The positioning seat 3 has evenly spaced connecting holes 301, which correspond to the mounting holes 202. This structure allows the positioning seat 3 and the mounting seat 2 to be fastened together with bolts, ensuring the reliability of the positioning seat 3. A shock-absorbing structure can be installed between the positioning seat 3 and the train to further guarantee the reliability of the positioning seat 3. The main body 1 of the online measuring device also has a positioning rod 5, with a vertically extending limiting adjustment groove 502 inside the positioning rod 5. The upper end head 6 of the measuring mechanism is mounted on the positioning rod 5. One end of the positioning rod 5 has an integrally formed T-shaped positioning head 504, and the positioning... The rod 5 is also provided with a through hole 503 communicating with the limit adjustment groove 502. The upper end of the positioning seat 3 is provided with a limit groove 302, and the limit groove 302 is fastened to the positioning head 504. The upper end of the limit groove 302 is also fitted with a fastening block 4. The fastening block 4 has fastening holes 401 symmetrically provided at both ends. The size of the fastening block 4 is larger than the size of the positioning head 504. The fastening block 4 is fastened to the positioning seat 3 with bolts through the fastening holes 401. This structure can make the fastening block 4 stabilize the connection between the positioning rod 5 and the positioning seat 3. The positioning rod 5 is used for the installation and positioning of the upper end head 6 of the measuring mechanism. The positioning rod 5 is also provided with fastening grooves 501 symmetrically provided on both sides, communicating with the limit adjustment groove 502. The fastening grooves 501 are inserted into the fastening grooves 501 and are fastened to the rectangular seat 602. The fastening bolt 7, due to the rectangular seat 602 being located within the limiting adjustment groove 502, prevents the upper end 6 of the measuring mechanism from deflecting, thus achieving reliable positioning of the measuring mechanism mounting base 601. The lower end of the upper end 6 of the measuring mechanism is integrally provided with the rectangular seat 602 and the measuring mechanism mounting base 601, and the rectangular seat 602 is engaged within the limiting adjustment groove 502. The upper end of the measuring mechanism 6 is integrally provided with a wire-passing hole seat 603, and the cross-sectional shape of the upper end 6 corresponds to the shape of the through hole 503. Furthermore, the size of the upper end 6 is larger than the width of the limiting adjustment groove 502, and there is an overlapping area between the through hole 503 and the support plate 303. This structure allows the upper end 6 of the measuring mechanism to be fixed to the positioning rod 5 through the through hole 503.When the positioning rod 5 is fixed on the positioning seat 3, the upper end 6 of the measuring mechanism is in a non-removable state, effectively preventing the upper end 6 of the measuring mechanism from falling off. The limit adjustment groove 502 can be used to adjust the position of the upper end 6 of the measuring mechanism, thereby allowing the vision sensor, ultrasonic sensor, and other sensors used for online measurement mounted on the measuring mechanism mounting seat 601 to adjust their detection positions. The wire hole seat 603 is used for the passage of data cables to facilitate the positioning of the data cables.

[0018] Working principle: When using the online measuring device for this train coupler, firstly, sensors such as vision sensors and ultrasonic sensors for online measurement are installed on the measuring mechanism mounting base 601. The data cable is connected to the outside through the wire hole seat 603. Then, the upper end 6 of the measuring mechanism passes through the through hole 503 to the positioning rod 5. The upper end 6 of the measuring mechanism and the measuring mechanism mounting base 601 are respectively positioned above and below the positioning rod 5. The rectangular seat 602 is located in the limit adjustment groove 502, which restricts the upper end 6 of the measuring mechanism to prevent it from rotating. Then, the fastening bolt 7 is used to initially position the rectangular seat 602 from the fastening groove 501. Then, the positioning seat 3 is fixed, and the positioning seat 3 is clamped on the limit member 201 and connected through the mounting hole 202 and the connecting hole 3. In the coordination of 01, bolts are used to secure the positioning seat 3 and the mounting seat 2. The mounting seat 2 is welded to the train for basic positioning. Then, the positioning head 504 is snapped into the limiting groove 302. The support plate 303 is supported below the positioning rod 5, and there is an overlap area between the support plate 303 and the through hole 503 to prevent the measuring mechanism mounting seat 601 from falling off. Then, the fastening block 4 is snapped into the limiting groove 302, and the fastening block 4 and the positioning seat 3 are fastened through the fastening hole 401 to ensure the stability of the positioning rod 5. Finally, the position of the measuring mechanism mounting seat 601 relative to the train coupler 8 is adjusted as needed so that the train coupler 8 can reliably perform real-time online measurement processing through the online measuring device body 1, ensuring the safety of train operation, thereby completing a series of tasks.

[0019] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
