[0023] Embodiment 1:

[0024] Figure 1 It is a schematic diagram of the structure of the utility model, such as Figure 1 A rail monitoring sensor fixing device is shown, which is used to make the sensor 5 and the rail 4 fit tightly together. The fixing device includes a tightening rod 1, a fixing bracket and a sensor 5. The tightening rod 1 is connected to the fixing bracket, and the sensor 5 is arranged at the bottom of the rail 4. The fixing bracket in the utility model includes a vertical bracket 6, a horizontal frame 7 and a positioning card seat 8, which constitute a supporting frame of the entire device. The vertical bracket 6 provides stability in the vertical direction, and the horizontal frame 7 is fixed to the upper end of the vertical bracket 6. The positioning card seat 8 serves as a connecting platform for the tightening rod 1 to support the entire adjustment structure, which can ensure the correct positioning of the sensor 5 at the bottom of the rail 4 to prevent deviation. The cross frame 7 in the utility model is fixedly connected to the upper end of the vertical bracket 6, the tightening rod 1 and the cross frame 7 are screwed together by threads, one end of the tightening rod 1 passes through the cross frame 7 and is hinged with the stabilizing plate 3, and the stabilizing plate 3 is used to press the rail 4 against the sensor 5. Specifically, the stabilizing plate 3 acts directly on the rail 4, and can be flexibly adjusted with the up and down movement of the tightening rod 1 through the hinged connection with the tightening rod 1, ensuring that the rail 4 can be firmly pressed against the sensor 5 at any time. This design effectively transmits pressure, ensures that there is no gap between the sensor 5 and the rail 4, and maintains a good contact state even when the rail 4 vibrates or deforms.

[0025] The utility model has a U-shaped groove 801 on the positioning base 8, and the sensor 5 is installed inside the U-shaped groove 801. The U-shaped groove 801 on the positioning base 8 of the utility model is designed to accurately accommodate the sensor 5, ensuring that the sensor 5 can be firmly installed at a predetermined position at the bottom of the rail 4, avoiding inaccurate monitoring data caused by installation deviation. The shape of the U-shaped groove 801 adapts to the contour of the sensor 5, so that the sensor 5 is in close contact with the surface of the rail 4, thereby improving the sensitivity and accuracy of monitoring.

[0026] The tightening rod 1 in the utility model is a cross-shaped structure, and the tightening rod 1 is a key adjustment element in the entire fixing device. It is connected to the cross frame 7 by a threaded connection, allowing the operator to adjust the upper and lower positions of the tightening rod 1 by rotation, thereby controlling the pressure of the stabilizing plate 3 on the rail 4. The cross-shaped structural design allows the operator to apply force easily, improving the convenience and flexibility of use. The spring 2 of the outer sleeve further increases the adaptability of the device, and can automatically adjust when the force on the rail 4 changes, maintaining the close contact between the sensor 5 and the rail 4, while reducing component damage caused by over-tightening; the utility model is provided with a spring 2 on the outer sleeve of the tightening rod 1, which can ensure that the tightening rod 1 is always in a tightened state, thereby ensuring the stability of the sensor 5, maintaining sufficient clamping force to ensure accurate monitoring of the sensor 5, and avoiding excessive static preload force from causing damage to the rail 4 or the sensor 5 itself.

[0027] The installation method of the utility model is as follows: during installation, the sensor 5 is first placed at an appropriate position at the bottom of the rail 4, and then the sensor 5 is fixed below the rail 4 by the bayonet U-shaped groove, and the tightening rod 1 is tightened so that the stabilizing plate 3 is firmly above the rail 4 and the sensor 5 is firmly fixed between the bayonet and the rail 4, and finally the tightening rod 1 is connected to the cross frame 7 by the spring 2, and the spring 2 is kept in a stretched state. The utility model has a U-shaped groove 801 in the positioning holder 8, and the sensor 5 can be fixed in the U-shaped groove 801 by tightening the rod 1 and the stabilizing plate 3, so that the sensor 5 and the rail 4 fit closely to each other.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it.
