[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1 , Figure 2 and Figure 3 , the utility model provides an embodiment: a wheel-push device for a railway vehicle, comprising a bottom plate 1, a fixed block 7 is arranged on the top of the bottom plate 1, a double-headed motor 12 is installed on the top of the fixed block 7, the output ends of the double-headed motor 12 are fixedly connected with a fixed rod 10, one end of the outer wall of the fixed rod 10 is fixedly connected with a gear 11, and the other end of the outer wall of the fixed rod 10 is fixedly connected with a push roller 9, the left and right sides of the top wall of the bottom plate 1 are fixedly connected with a sawtooth bar 5, the gear 11 is meshed with the sawtooth bar 5, the left and right sides of the bottom plate 1 are provided with rails 6, and the front side of the fixed block 7 is provided with a marking mechanism 2; the inner side of the push roller 9 is installed with a sensor 13; the front and rear sides of the top of the bottom plate 1 are threadedly connected with bolts 3; the left and right sides of the bottom of the fixed block 7 are fixedly connected with slide bars 8, and the left and right sides of the top wall of the bottom plate 1 are provided with slide grooves 4, and the slide bars 8 are respectively slidably connected with the corresponding slide grooves 4;

[0028] Specifically, the base plate 1 is installed at the specified position by bolts 3 to ensure the stability of the base plate 1; then, the double-headed motor 12 is started, which will drive the fixed rod 10 to rotate; this design makes the operation easier and does not require manual intervention; the rotation of the fixed rod 10 drives the gear 11 to rotate synchronously, thereby driving the push roller 9 to move; this design improves the transmission efficiency of the device and makes the whole process smoother; at the same time, the rotation of the gear 11 is meshed with the sawtooth bar 5 for transmission, further enhancing the transmission stability; during the movement of the double-headed motor 12, it also drives the slide bar 8 to slide in the slide groove 4; this design provides a plan for the movement trajectory of the double-headed motor 12, making the movement process more precise; in addition, this design also enables the device to adapt to various complex environments and has strong adaptability; it is worth mentioning that the device is also equipped with a sensor 13; during the movement of the double-headed motor 12, the sensor 13 will detect the surrounding environment; this enables the device to grasp environmental changes in real time and respond in time, thereby improving the accuracy of the test.

[0029] Reference Figure 2 and Figure 3 The marking mechanism 2 includes an arc rod 201, which is fixedly connected to the front end of the fixed block 7, and the end of the arc rod 201 is fixedly connected to a fixed disk 202, and the top of the fixed disk 202 is fixedly connected to an electric push rod 203, and the output end of the electric push rod 203 passes through the fixed disk 202 and is fixedly connected to a piston 204, and the bottom of the fixed disk 202 is fixedly connected to a hollow tube 205;

[0030] Specifically, the sensor 13 plays a vital role in the normal production process; the sensor 13 is like the eyes of the production line, always monitoring the quality of the product; once an unqualified area is detected, the sensor 13 will immediately transmit the signal to the electric push rod 203; the electric push rod 203 is the actuator on the production line. When it receives the unqualified signal from the sensor 13, it will start quickly to process the unqualified product; to achieve this goal, the electric push rod 203 moves by telescopic driving piston 204; this design allows the ink in the hollow tube 205 to be effectively squeezed out, and the unqualified parts are marked in real time; ensure product quality: timely discovery and processing of unqualified products helps to ensure the quality of the final product and reduce manual intervention: the automated processing process reduces the need for manual intervention, reduces operating errors, and improves the stability of the production line; facilitates troubleshooting: real-time marking of unqualified parts helps to quickly locate and troubleshoot faults and improve maintenance efficiency.

[0031] Reference Figure 1 and Figure 3 The two hollow tubes 205 are symmetrically designed; the outer wall of the push roller 9 is rounded;

[0032] Specifically, the symmetrically designed hollow tube 205 increases the accuracy of marking, and the rounded outer wall reduces the possibility of friction and collision.

[0033] Working principle: Install the bottom plate 1 at the specified position through the bolts 3, turn on the double-headed motor 12 to drive the fixed rod 10 to rotate, and the rotation of the fixed rod 10 causes the gear 11 to rotate synchronously with the push roller 9. The rotation of the gear 11 is meshed with the sawtooth bar 5 to drive the double-headed motor 12 to move. When the double-headed motor 12 moves, it drives the slide bar 8 to slide in the slide groove 4. The movement trajectory of the double-headed motor 12 is planned, and the push roller 9 moves along the trajectory of the rail 6 through the movement of the double-headed motor 12, so that the sensor 13 performs detection work without manual follow-up to record the test, which is time-saving and labor-saving and can meet the needs of use. The marking mechanism 2 moves synchronously through the movement of the fixed block 7, and is connected to the electric push rod 203 through the signal transmission of the sensor 13. When an unqualified area is detected, the sensor 13 starts the electric push rod 203, and the electric push rod 203 is retracted to drive the piston 204 to move, thereby squeezing out the ink stored in the hollow tube 205, and the unqualified area can be marked in real time, which brings convenience to use.
