[0002] With the rapid development of rail transit in my country, railway construction has reached a new height. The dense railway network has promoted the development of social economy, but at the same time, some safety hazards in track operation have also been exposed. High-speed railways have very high requirements for the smoothness of tracks. As the most important component of the high-speed railway track structure, rails are directly related to driving safety and are the focus of safety risk prevention and control in high-speed railway maintenance and repair. Under the condition of long-term high-speed operation, due to the coupling of factors such as train impact, fatigue effect, and temperature effect, the foundation roadbed below the line will be damaged to a certain extent, causing deformation and deterioration of bearing capacity. Once an accident occurs, the consequences are disastrous. In response to this phenomenon, the monitoring of the lateral displacement of high-speed rail tracks is often achieved through regular manual inspections or by setting displacement sensors beside the tracks.

[0003] In the prior art, when the displacement of the high-speed railway track is monitored by a displacement sensor, the staff is required to install the displacement sensor on a mounting frame preset on the ground on both sides of the track through multiple bolts. If multiple displacement sensors need to be installed on both sides of the high-speed railway track, the staff is required to spend a long time repeatedly tightening the screws, which makes the installation of the displacement sensor labor-intensive and inconvenient for the staff. In addition, the displacement sensors installed on both sides of the high-speed railway track are fixed monitoring structures, which cannot be adjusted in an emergency according to actual monitoring needs, and do not have fast and accurate self-adjustment performance to deal with emergencies.

[0029] As a technical optimization solution in the utility model, a first screw rod 4 is rotatably installed inside the fixed rod 2, and a moving seat 10 is installed on the outer wall of the first screw rod 4. The outer wall of the moving seat 10 on the side away from the fixed rod 2 is connected to the rotating rod 3 through the rotating shaft 13. In actual use, a first servo motor is preset at one end of the fixed rod 2, and the output end of the first servo motor is connected to the end of the first screw rod 4, thereby driving the first screw rod 4 to rotate inside the fixed rod 2, so that the moving seat 10 can move up and down inside the fixed rod 2; a second servo motor is preset inside the moving seat 10, and the output end of the second servo motor is connected to the rotating shaft 13, so that the rotating shaft 13 and the rotating rod 3 can be driven to rotate and adjust.

[0030] As a technical optimization solution in the utility model, two telescopic limit rods 12 are installed inside the movable seat 10, and a plug hole adapted to the telescopic ends of the two telescopic limit rods 12 is opened on the outer wall of the rotating rod 3 close to the fixed rod 2. The two telescopic limit rods 12 are electric telescopic rods. After the rotating rod 3 rotates to a horizontal state, the telescopic ends of the two telescopic limit rods 12 extend and are inserted into the plug hole opened on the outer wall of the rotating rod 3, so as to assist in limiting and fixing the position of the rotating rod 3 after rotation.

[0031] As a technical optimization solution in the utility model, the second screw rod 5 is rotatably installed inside the rotating rod 3, and the moving block 11 is installed on the outer wall of the second screw rod 5.

[0032] As a technical optimization solution in the present utility model, the installation component includes two sets of driving rods 19 rotatably installed on the upper and lower outer walls of the moving block 11, and the ends of the two sets of driving rods 19 away from the moving block 11 are both installed with arc plates 16, and the outer walls on both sides of the equipment body 6 are provided with grooves 15 adapted to the arc plates 16, and the rotating parts of the two sets of driving rods 19 are both installed with torsion springs. The two sets of driving rods 19 are controlled to drive the arc plates 16 to rotate in the direction away from each other, so that the installation groove 14 inside the moving block 11 is exposed, so that one end of the equipment body 6 can be directly inserted into the installation groove 14. After the restriction on the driving rods 19 is released, the two arc plates 16 can be driven to rotate to the inside of the grooves 15 opened on the outer walls on both sides of the equipment body 6 with the help of the torsion spring, so as to achieve the effect of quickly installing and fixing the equipment body 6.

[0033] As a technical optimization solution in the utility model, two slide grooves 18 are provided on the top of the moving block 11, and sliders 20 are installed inside the two slide grooves 18. The ends of the two sliders 20 away from the slide grooves 18 are commonly connected to the first abutment block 22, and the top of the first abutment block 22 is connected to the second abutment block 23 through the connecting rod 17. By pushing the first abutment block 22 to move away from the rotating rod 3 at the top of the moving block 11, the first abutment block 22 can be driven to push the ends of the two driving rods 19 away from the arc plate 16, driving the two arc plates 16 to rotate in the direction away from each other, and pushing the first abutment block 22 to move toward the direction close to the rotating rod 3 can drive the second abutment block 23 to push the two driving rods 19, driving the two arc plates 16 to rotate in the direction close to each other.

After the connecting block 21 on the outer wall of the first abutting block 22 is moved to a position corresponding to the plug hole on the top of the moving block 11, the positions of the first abutting block 22 and the second abutting block 23 can be limited and fixed by passing the two plug holes downward with the help of an external fixing frame, driving the positions of the two arc-shaped plates 16 that rotate in the direction of approaching each other to be fixed, so as to facilitate the blocking of the installation groove 14.

[0035] In the utility model, when used in the case where the width of both sides of the high-speed railway track is wider, the fixing rod 2 can be directly used after being installed with the base 1 through multiple bolts 8. When used in the case where the width of both sides of the high-speed railway track is narrower, holes can be drilled on the railing surface at designated positions on both sides of the high-speed railway track according to actual usage requirements. After the base 1 is removed, the fixing rod 2 can be installed on the railing surface at designated positions on both sides of the track with the help of multiple bolts 8, which facilitates the monitoring of the high-speed railway track by the equipment body 6 and can also improve the applicability of the equipment body 6.

[0036] When the device body 6 needs to be installed inside the moving block 11 for use, the connecting rod 17 can be pinched by one hand and pushed in the direction away from the rotating rod 3, driving the first abutment block 22 to push the ends of the two driving rods 19 that are close to each other, thereby driving the two arc plates 16 to rotate in the direction away from each other. After inserting one end of the device body 6 into the installation groove 14 with the other hand, the control of the connecting rod 17 is released, and the two driving rods 19 and the arc plates 16 are automatically rotated and reset with the help of the elastic reset of the two torsion springs, so that the ends of the two arc plates 16 that are close to each other enter the grooves 15 on both sides of the device body 6 after rotation and reset, thereby achieving the effect of quickly installing and fixing the device body 6 inside the moving block 11, which is convenient for the staff to quickly install multiple device bodies 6.

[0037] When the device body 6 needs to be disassembled, the above steps can be repeated to drive the two arc plates 16 to rotate and move out from the inside of the groove 15, and the device body 6 can be manually taken out from the installation groove 14, which is convenient for the staff to quickly disassemble multiple device bodies 6.

[0038] If the device body 6 is damaged during use and it is removed from the inside of the moving block 11, if it is not installed again in the moving block 11 in time after a period of time, the connecting rod 17 can be pushed toward the direction close to the rotating rod 3, driving the second abutment block 23 to push the end of the two driving rods 19 that is close to each other, driving the two arc plates 16 to rotate in the direction of approaching each other, blocking the installation groove 14, and after the connecting rod 17 drives the first abutment block 22 to move to the specified position, with the help of an external fixing part, the positions of the first abutment block 22 and the second abutment block 23 are synchronously limited and fixed, driving the two arc plates 16 to maintain the state of blocking the installation groove 14, to avoid the problem that foreign birds or insects enter the installation groove 14 when there is no device body 6 inside the installation groove 14, affecting the subsequent use of the installation groove 14.

[0039] During the use of the equipment body 6, if it is necessary to adjust the use height of the equipment body 6, the first screw rod 4 can be used to drive the movable seat 10 and the rotating rod 3 to move up and down together, thereby being able to drive the use height of the equipment body 6 to be adjusted. After controlling the rotating rod 3 to rotate to a state parallel to the fixed rod 2, the movable block 11 can be controlled to continue to move upward on the surface of the second screw rod 5, thereby being able to further adjust the use height of the equipment body 6, making it convenient for the equipment body 6 to monitor the high-speed rail track at different heights.

[0040] If it is necessary to adjust the horizontal position of the equipment body 6, the second screw 5 inside the rotating rod 3 which is in a horizontal state can be controlled to rotate, driving the moving block 11 and the equipment body 6 to move back and forth together, and the horizontal position of the equipment body 6 can be adjusted, thereby facilitating the improvement of the monitoring range of the equipment body 6 on the high-speed rail track and improving the performance of the equipment body 6.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
