AI Technical Summary
The fixed structure of the existing rail vibration sensor has a low degree of fit with the side of the rail, and it cannot effectively resist the vibration of the rail, resulting in the sensor offset and affecting the contact quality.
A fixed structure including rails, recesses, positioning holes, telescopic springs, sliders, linkage rods and sliders is designed. The deformation of the telescopic springs generates interaction forces, and pushes the vibration sensor to maintain close contact with the rails and prevent offsets.
It ensures that the vibration sensor always comes in close contact when the rail is vibrating, avoids deviation problems caused by long-term vibration, and improves the stability and contact quality of the sensor.

[0002] Rails are an important part of railway transportation. Whether it is seamless rails or ordinary rails, seasonal changes, temperature changes, maintenance and construction, and even the normal operation of trains on the rails will cause changes in rail stress. In order to ensure the safety of train driving, it is necessary to monitor the running status of the train through a ground monitoring system.
[0003] The Chinese patent publication number is: CN210344937U discloses a fixing device for clamping a sensor on the side of a rail. The application states: "The existing sensor fixing structure has a low fit with the rail and cannot be well fixed to the side of the rail. In addition, the position of the sensor cannot be dynamically adjusted during the installation and fixing of the sensor. After the sensor is fixed, its height or offset does not meet the requirements and needs to be removed and reinstalled, which is time-consuming and labor-intensive." Although the application solves this problem, it has the following defects:
[0004] The above-mentioned prior art solutions have the following defects: although the above-mentioned device solves the problem of low fit between the fixed structure and the rail, the rail will have a certain vibration amplitude when the train passes, which may easily cause the sensor to shift over a long period of time, resulting in poor contact between the sensor and the rail. Therefore, we propose a new type of rail vibration sensor fixing structure. Utility Model Content

[0026] See also Figure 1-3 The right end of the telescopic spring 8 is fixedly mounted on the inner wall of the spring cavity 6, wherein the cross bar 7 runs through the entire telescopic spring 8. By setting the telescopic spring 8 to a compressed state, it is convenient to indirectly utilize the interaction force to push the vibration sensor 12 to the left, thereby ensuring that the vibration sensor 12 is always in close contact with the rail 1.
[0027] See also Figure 1 and Figure 3 The slide plate 9 is slidably connected to the cross bar 7, and the cross bar 7 can limit the movement trajectory of the slide plate 9 and assist the slide plate 9 to move.
[0028] See also Figure 1 and Figure 3 The slider 14 is slidably connected to the inside of the slide rail 15. The slider 14, the slide rail 15 and the linkage rod 13 cooperate with each other to guide the slide plate 9, so that the slide plate 9 moves more stably during the movement.
[0029] See also Figure 1-3 The vertical length of the positioning rod 5 is greater than the sum of the vertical lengths of the first positioning hole 2 and the second positioning hole 4. By setting the vertical length of the positioning rod 5 to be greater than the sum of the vertical lengths of the first positioning hole 2 and the second positioning hole 4, it is convenient to use the positioning rod 5 to pass through the first positioning hole 2 and the second positioning hole 4, and firmly fix the recessed part 3 on the rail 1.
[0030] See also Figure 1-3 The concave part of the concave part 3 fits with one side of the rail 1. By fitting the concave part of the concave part 3 with one side of the rail 1, the concave part 3 can be quickly installed on the rail 1, and the concave part 3 and the rail 1 fit more closely, which is convenient for daily use.
[0031] The working principle of the utility model is as follows: when installing the device, first install the concave member 3 on the rail 1, and make the first positioning hole 2 and the second positioning hole 4 on the same vertical line, and then use the positioning rod 5 to rotate into the first positioning hole 2 and the second positioning hole 4 to complete the installation of the concave member 3. At this time, the vibration sensor 12 will contact the rail 1, and the telescopic spring 8 will be in a compressed state. The telescopic spring 8 is always in a compressed state, which will generate an interaction force opposite to the elastic force. The interaction force will push the slide plate 9 to move to the left or make the slide plate 9 have a tendency to move to the left. At the same time, the linkage rod 1 3. The use of the slider 14 and the slide groove 15 together will make the slider 9 move to the left more stably. The slider 9 indirectly drives the vibration motor 12 to move to the left, so that the left end of the vibration motor 12 is always in contact with and squeezed with the rail 1. When the rail 1 vibrates, the telescopic spring 8 will undergo corresponding deformation and generate an interaction force opposite to the elastic force. The interaction force will push to the left, so that the vibration motor 12 is always in close contact with the rail 1, which can avoid the deviation of the vibration sensor 12 due to the long-term vibration of the rail 1, thereby ensuring that the vibration sensor 12 is in good contact with the rail 1.
