The following describes the embodiments of the present invention based on its overall structure.

[0026] Reference Figures 1 to 5In one embodiment of the present invention, the magnetic levitation contact rail cold sliding device is used to inspect the side contact rails of a magnetic levitation track. The magnetic levitation track includes a support beam 1, a support platform 2 fixedly connected to the support beam 1, two F-shaped steel bars 3 symmetrically fixedly connected to the support platform 2, and a sensing plate 4 fixedly connected to the F-shaped steel bars 3. Side contact rails 16 are symmetrically fixedly connected to the two outer side surfaces of the support beam 1.

[0027] The magnetic levitation contact rail cold sliding device includes a support mechanism, a drive mechanism, and a detection mechanism. The support mechanism is located above the F-shaped steel bar, and the drive mechanism and detection mechanism are fixed to the support mechanism. The drive mechanism is used to drive the support mechanism to move along the F-shaped steel bar, thereby driving the detection mechanism. The detection mechanism includes a photoelectric distance sensor corresponding to the side contact rail, which is used to continuously detect the side contact rail during movement.

[0028] The supporting mechanism includes a supporting beam 5, which is arranged above two F-shaped steel bars 3, and a driving cabinet 6 is fixedly connected to the top of the supporting beam 5. Slide arm fixing seats 7 are symmetrically fixedly connected at both ends of the supporting beam 5, and each slide arm fixing seat 7 is symmetrically fixedly connected to two roller fixing seats 8 near the side of the supporting beam 5. A group of two upper supporting rollers 9 are rotatably connected to the inner side of each roller fixing seat 8, and each upper supporting roller 9 is tightly attached to the top of the F-shaped steel bar 3 to provide a stable supporting effect. A driving motor 10 is fixedly connected to the top of each slide arm fixing seat 7, and the rotating shaft of each driving motor 10 is connected to the rotating shaft of a group of upper supporting rollers 9 adjacent to it through a plurality of sprockets and chain transmissions to ensure that the upper support rollers 9 are stable when the track is not moving. When powered on, the upper support roller 9 is driven to rotate, providing power for the support beam 5 and other mechanisms to move. The two drive motors 10 are connected to the drive cabinet 6 through wires to provide power and control, driving the support beam 5 to move along the F-shaped steel bar 3. Each sliding arm fixing seat 7 is fixedly connected to a side arm support frame 11 on the side away from the support beam 5. Two side sliding arms 12 are symmetrically fixedly connected to the inner side of each side arm support frame 11, and a side limiting roller 13 is fixedly connected to the outer side of the side sliding arm 12. Each side limiting roller 13 is tightly attached to the side of the F-shaped steel bar 3 to provide a certain limiting effect, which is convenient for the cold sliding device to align with the test position and ensure the stability of the position of the support beam 5 and other structures during movement. A detection support arm 14 is fixedly connected to the bottom of each side arm support frame 11, and a photoelectric distance sensor 15 is fixedly connected to the side of the detection support arm 14 close to the support beam 1. Three photoelectric distance sensors 15 are fixedly connected to the inner side of each detection support arm 14, which are used to continuously detect the distance from the inner side of the detection support arm 14 to the top of the side contact rail 16, the upper side of the side contact rail 16 and the lower side of the side contact rail 16. Through such a design, when the supporting beam 5 moves along the direction of the F-shaped steel bar 3, the side contact rail 16 can be dynamically inspected to check the smoothness of the contact surface of the side contact rail 16 in all directions.

[0029] The drive cabinet 6, drive motor 10, roller fixing base 8, sprocket, chain and other structures constitute a drive mechanism. Of course, in other embodiments, the drive mechanism can also adopt other different structures.

[0030] The above-mentioned side arm support frame 11, detection support arm 14, photoelectric distance sensor 15 and other structures constitute a detection mechanism. Of course, in other embodiments, the detection mechanism can also adopt other different structures.

[0031] The working principle of this utility model is:

[0032] First, before using the magnetic levitation contact rail cold sliding device, perform necessary inspections on it, check the power supply of the drive cabinet 6, ensure that the two drive motors 10 can obtain sufficient power and control signals through the wires, confirm the initial position and sensitivity of the photoelectric distance sensor 15, and ensure that they can accurately measure different parts of the side contact rail 16;

[0033] After the preparation is completed, the drive motor 10 is activated through the drive cabinet 6, and the drive motor 10 starts to run. Through multiple sprockets and chain transmission connections, it drives the corresponding upper support roller 9 to roll above the F-shaped steel bar 3. The rolling of the upper support roller 9 provides a stable support effect and drives the entire support beam 5 and the structure on it to move along the direction of the F-shaped steel bar 3.

[0034] As the supporting beam 5 moves, the side limit roller 13 is in close contact with the side of the F-shaped steel bar 3, providing a certain limiting effect, ensuring that the cold sliding device can maintain relatively stable movement and accurately align with the test position. At this time, the photoelectric distance sensor 15 starts to work, and continuously detects the distance from the inner side of the support arm 14 to the top of the side contact rail 16, the upper side of the side contact rail 16, and the lower side of the side contact rail 16. These distance data are collected in real time and used to analyze the smoothness of the contact surface of the side contact rail 16 in all directions.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
