[0017] The principles and characteristics of the utility model are described below in combination with the drawings, and the examples are only used for explaining the utility model and are not used for limiting the scope of the utility model.

[0018] As shown in the drawings, Fig. 1 A support rod type scribing shaft template comprises a claw 1, a first fixed block 2, a bottom plate 3, a second fixed block 4, a support rod 5 and an adjusting wheel 6; the claw 1 is assembled on the rail surface of a steel rail, the first fixed block 2 is arranged on the claw 1, the bottom plate is arranged on the first fixed block 2, the second fixed block 4 is arranged on the bottom plate 3, the first fixed block 2 and the second fixed block 4 are respectively located on the two surfaces of the bottom plate 3, the support rod 5 is arranged between the bottom plate 3 and the adjusting wheel 6, the adjusting wheel 6 is arranged on the rail surface of the steel rail, and the bottom plate 3 is perpendicular to the rail surface of the steel rail. The end of the support rod 5 is provided with an insulating joint 7, the insulating joint 7 is arranged on the bottom plate 3, and the track circuit is avoided from being short-circuited through the insulating joint 7.

[0019] The claw 1 is assembled on the rail surface of the steel rail, which plays a role in fixing and supporting the whole template, and ensures that the template can be stably attached to the steel rail and will not move or shake when the train passes or is simulated. The first fixing block 2 is arranged on the claw 1, which is a key component connecting the claw 1 and the bottom plate 3, and plays a role in transmitting and dispersing force. The design of the first fixing block 2 needs to ensure the close connection with the claw 1, and at the same time provide sufficient support area to disperse the pressure transmitted by the bottom plate 3, and facilitate the carrying of the template. The bottom plate 3 is the main bearing component of the template, which plays a role in supporting and connecting. The design of the bottom plate 3 needs to be strong enough to withstand the pressure from the supporting rod 5 and the adjusting wheel 6, while maintaining a vertical relationship with the rail surface of the steel rail. The second fixing block 4 is arranged on the bottom plate 3, opposite to the first fixing block 2, which plays a role in further fixing and supporting the bottom plate 3. The design of the second fixing block 4 needs to ensure the close connection with the bottom plate 3, and at the same time provide additional support points to enhance the stability of the whole template. The supporting rod 5 is arranged between the bottom plate 3 and the adjusting wheel 6, which is one of the key components of the template, and plays a role in transmitting and supporting force, transmitting the pressure of the adjusting wheel 6 to the bottom plate 3, thereby realizing the function of simulating cutting or changing the magnetic field of the rail surface of the steel rail. The adjusting wheel 6 is arranged on the rail surface of the steel rail, opposite to the supporting rod 5, which can simulate the cutting or changing of the magnetic field by adjusting the position or angle when the train wheel passes through the sensor, and adjust the state of the bottom plate 3, so that the bottom plate 3 is in a vertical state with the rail surface.

[0020] As shown in Fig. 2 The claw 1 includes a clamping seat 10, a clamping cavity 11 opened in the side end face of the clamping seat 10, and a clamping groove 12 arranged on the lower end face of the clamping seat 10. The first fixing block 2 is arranged in the clamping cavity 11. The clamping groove 12 of the claw 1 is assembled on the rail surface of the steel rail, and the shape of the clamping groove 12 of the claw 1 is matched with the shape of the rail surface of the steel rail. A positioning hole is arranged on the claw 1 near the clamping cavity 11, and a through hole corresponding to the positioning hole is arranged on the first fixing block 2. A positioning pin 13 penetrates the positioning hole and the through hole to connect the claw 1 and the first fixing block 2. The clamping seat 10 is the main part of the claw 1, which bears the key structures such as the clamping cavity 11 and the clamping groove 12. The clamping cavity 11 is opened in the side end face of the clamping seat 10, which is used to accommodate and fix the first fixing block 2. The shape and size of the clamping cavity 11 are matched with the first fixing block 2, so as to ensure the close connection and stable support of the two. The clamping groove 12 is arranged on the lower end face of the clamping seat 10, which is used to be assembled on the rail surface of the steel rail. The shape of the clamping groove 12 is matched with the shape of the rail surface of the steel rail, so as to ensure that the claw 1 can be stably fixed on the steel rail and will not move or shake during the simulation test.

[0021] The supporting rod 5 can be a fixed structure or a telescopic structure. When it is a telescopic structure, as shown in Fig. 3As shown, the support rod 5 includes an outer rod 50 and an inner rod 51, the inner rod 51 is inside the outer rod 50 and slides along the outer rod 50, the end of the outer rod 50 away from the inner rod 51 is arranged on the insulating joint 7, and the end of the inner rod 51 away from the outer rod 50 is connected to the adjusting wheel 6. The sliding of the inner rod 51 along the outer rod 50 realizes the adjustment of the overall length of the support rod 5, so as to simulate different sizes of train wheels or different cutting angles, so as to realize the accurate test of the performance of the sensor.

[0022] When the template is used, the specific working process is as follows:

[0023] Installation and fixation: first, the clamping jaw 1 is assembled on the rail surface of the steel rail and fixed. Then, the first fixed block 2 is installed on the clamping jaw 1, and the bottom plate 3 is installed on the first fixed block 2. Then, the second fixed block 4 is installed on the bottom plate 3, and the first fixed block 2 and the second fixed block 4 are respectively located on the two surfaces of the bottom plate 3. Finally, the support rod 5 and the adjusting wheel 6 are installed in place, and the position and angle of the adjusting wheel 6 are adjusted to keep a vertical relationship with the rail surface of the steel rail.

[0024] Simulation test: after the installation and fixation of the support rod type template, the simulation test can be carried out. By adjusting the position and angle of the adjusting wheel 6, different situations of the train wheel passing through the sensor are simulated. During the test, the output signal of the sensor is observed to ensure that it can accurately capture the axle pulse signal generated when the adjusting wheel 6 cuts or changes the magnetic field line.

[0025] Calibration and optimization: according to the results of the simulation test, the sensor can be calibrated and optimized. By adjusting the sensitivity and response time of the sensor and other parameters, it can more accurately detect the passing of the train wheel.
