[0030] like Figures 1 to 4 As shown, an inspection vehicle device for a tunnel includes: a beam support 1, a metal track 2, a track vehicle 3, a protective fence 4 and a protective moving mechanism 5;

[0031] The beam supports 1 are equidistantly arranged at both ends of the inner wall of the tunnel. The beam supports 1 are integrated and installed with the tunnel through embedded steel bars and fixed so that they are the same as the tunnel track. The metal track 2 is arranged on the beam support 1, and the metal track 2 is fixedly connected by bolts, thereby providing the structure on the metal track 2 with stable horizontal movement. The rail car 3 is horizontally slidably connected to the metal track 2. The rail car 3 is driven by a reducer chain so that it travels above the track. The front end is the driven part and the rear section is the active part. The tunnel track has a curved part, which can have better passing performance. There are anti-collision mechanisms and clamps at the front and rear ends to ensure construction and safe parking. The above is the existing technology and will not be repeated below. The protective fence 4 is fixed on both sides above the rail car 3. The protective fence 4 is fixedly connected by bolts, thereby providing effective protection for the personnel on the rail car 3.

[0032] The protective movement mechanism 5 is arranged on the outer wall of the rail car 3. The protective movement mechanism 5 can provide personnel with a way to climb onto the rail car 3, and can effectively protect the personnel on the rail car 3 during the personnel's work. The protective movement mechanism 5 has a fixed block 501 fixed on the outer wall of the rail car 3. The fixed block 501 is fixedly connected by bolts. The cross-section of the fixed block 501 is "L" shaped. The hole opened inside the fixed block 501 is welded with a bearing, thereby providing the internal structure with stable rotation.

[0033] The connecting shaft 502 connected to the inside of the fixed block 501 is rotated. The connecting shaft 502 can drive the structure on the shaft to rotate synchronously during the rotation process. The protective moving mechanism 5 also includes a connecting block 503 fixed on the connecting shaft 502. The connecting block 503 can provide a connection with the connecting shaft 502, so as to change the angle synchronously. The driving motor 504 is fixed on the outer wall of the rail car 3. The driving motor 504 is fixedly connected by bolts, and the output end of the driving motor 504 is connected to the connecting shaft 502. The driving motor 504 can provide the connecting shaft 502 with an angle change, thereby driving the connecting shaft 50 2, the angle of the structure on the first ladder 505 is changed synchronously, the first ladder 505 welded on the connecting block 503, the first ladder 505 can provide people with climbing, a slide groove 506 is opened at one end of the outer wall of the first ladder 505, the slide groove 506 can provide the internal structure to move stably on the outer wall of the first ladder 505, and the second ladder 507 is slidably connected to the inside of the slide groove 506. The second ladder 507 can provide people with a longer distance to climb after moving, making it more convenient for people to climb. A circular hole is opened on the outer wall of the second ladder 507, and the circular hole opened can provide the setting of the internal structure.

[0034] When personnel need to carry out subsequent tunnel operations on the rail car 3, the drive motor 504 is started, and the drive motor 504 drives the connecting shaft 502 inside the fixed block 501 to rotate. During the rotation of the connecting shaft 502, the connecting block 503 on the connecting shaft 502 can be provided to rotate synchronously. At this time, the first ladder 505 located on the side of the protective fence 4 above the connecting block 503 will rotate 180°. At this time, the second ladder 507 in the chute 506 outside the first ladder 505 will move vertically downward, thereby allowing personnel to climb onto the rail car 3 through the first ladder 505 and the second ladder 507, and start the rail car 3, so that the rail car 3 can be provided to move horizontally through the metal track 2 on the beam support 1 to the designated position in the tunnel that needs maintenance.

[0035] An inspection vehicle device for use in a tunnel, comprising: a guide rod 508, a bidirectional motor 509, a winding wheel 510, a mounting block 511, and a steel wire rope 512;

[0036] The guide rod 508 welded on the outer wall of the connecting block 503 can provide the structure on the rod with stable sliding displacement, and the guide rod 508 passes through the circular hole connected to the second ladder 507. The circular hole opened in the second ladder 507 is adapted to the diameter of the guide rod 508, which can provide the second ladder 507 with stable movement. The bidirectional motor 509 is arranged on the outer wall of the connecting block 503, and the bidirectional motor 509 is fixedly connected by bolts, thereby providing the structure connected to the output ends at both ends with stable rotation. The winding wheel 510 connected to the output ends on both sides of the bidirectional motor 509 by an axis can drive the outer wound structure to rotate synchronously during the rotation process.

[0037] The mounting block 511 welded on the outer wall of the second ladder 507 can serve as a fixed connection between structures, and the cross-section of the mounting block 511 is in a "U" shape, which can be more stable during the connection process. The wire rope 512 with one end wound on the winding wheel 510 serves as a connection between the structures. During the rotation on the winding wheel 510, it can drive the structure at the other end to move, and the other end of the wire rope 512 is connected to the mounting block 511. During the winding process, the wire rope 512 drives the mounting block 511 to move.

[0038] When the second ladder 507 needs to move through the slide 506, starting the bidirectional motor 509 can drive the winding wheel 510 to rotate. At this time, the winding wheel 510 can drive the wire rope 512 wound on the winding wheel 510 to move during the rotation. The other end of the wire rope 512 is connected to the second ladder 507 through the mounting block 511, thereby providing the second ladder 507 with stable movement inside the guide rod 508.

[0039] Working principle:

[0040] When personnel need to perform subsequent tunnel operations on the rail car 3, the drive motor 504 is started, and the drive motor 504 drives the connecting shaft 502 inside the fixed block 501 to rotate. During the rotation of the connecting shaft 502, the connecting block 503 on the connecting shaft 502 can be provided with synchronous rotation. At this time, the first ladder 505 located on the side of the protective fence 4 above the connecting block 503 will rotate 180°.

[0041] When the second ladder 507 needs to move through the slide 506, starting the bidirectional motor 509 can drive the winding wheel 510 to rotate. At this time, the winding wheel 510 can drive the wire rope 512 wound on the winding wheel 510 to move during the rotation. The other end of the wire rope 512 is connected to the second ladder 507 through the mounting block 511, thereby providing the second ladder 507 with stable movement inside the guide rod 508. At this time, the second ladder 507 in the slide 506 outside the first ladder 505 will move vertically downward, thereby providing personnel with the ability to climb to the rail car 3 through the first ladder 505 and the second ladder 507.

[0042] The rail car 3 is started, and the rail car 3 is moved horizontally to a designated position in the tunnel that needs maintenance via the metal rails 2 on the beam support 1 .
