[0046] A using method of a maintenance device with a walking rail support assembly for a tunnel, which comprises the following steps:

[0047] S1. First, place multiple groups of walking rails 3 on the ground where they need to be installed, then splice and install the multiple groups of walking rails 3 end to end, and then slidably snap the limiting driving device 1 on the upper surface of the walking rail 3, so as to complete the assembly between the limiting driving device 1 and the walking rail 3;

[0048] S2. Then the staff steps onto the upper surface of the support device 2, and then controls the operation of the limiting driving device 1, so that the support device 2 slides inside the limiting driving device 1, so as to drive the staff to move at the top inside the tunnel, so as to facilitate the staff to repair the inner surface of the tunnel;

[0049] S3. When repairing the inner surface of the tunnel, first start the pump 9 to convey the material inside the storage cylinder 10 to the grouting nozzle 25, and convey the material into the cracks inside the inner surface of the tunnel, so as to repair the cracks inside the tunnel;

[0050] S4. Then control the limiting driving device 1 to move on the upper surface of the walking rail 3, so as to facilitate the limiting driving device 1 to transport the staff, so as to continue to comprehensively repair the inner surface of the tunnel.

[0051] Working principle of Embodiment 1: When repairing the inner surface of a tunnel, first place multiple groups of walking rails 3 on the ground where they need to be installed, and then connect and install the multiple groups of walking rails 3 end to end. When assembling between the walking rails 3, first align and snap the clamping block 33 at one end of the walking rail 3 with the clamping groove 35 at one end of another group of walking rails 3. Then, slide and snap the arc-shaped clamping rods 11 at both ends of the bottom of the limit driving device 1 with the columnar rails at one end of the upper surface of the walking rail 3 until the limit driving device 1 is slidably installed on the upper surface of the walking rail 3, thus completing the assembly between the limit driving device 1 and the walking rail 3. Then, the staff climbs onto the upper surface of the support device 2 and operates the controller 28 to control the second driving motor 20 to rotate. When the second driving motor 20 rotates, it will drive the transmission shaft 16 to rotate synchronously through the transmission sprockets 19 and the transmission chain 18. When the transmission shaft 16 rotates, it will drive the transmission belt 6 connected to its outer surface to rotate synchronously. When the transmission belt 6 rotates, it will drive the connecting block 31 to slide synchronously with the transmission belt 6. When the connecting block 31 slides, it will drive the support base 29 connected to the bottom to slide synchronously through the limit rotating shaft 30, so that the support base 29 transports the staff until the staff is transported to the crack on the inner surface of the tunnel. Then, the staff moves the grouting nozzle 25 to the crack, and then controls the pump 9 to operate to transport the material inside the storage cylinder 10 into the inside of the delivery pipe 23, and the delivery pipe 23 transports the material into the inside of the grouting nozzle 25 until the material is transported into the crack, thus completing the work of repairing the crack. When repairing other parts inside the tunnel, it is necessary to move the position of the limit driving device 1. When adjusting the position of the limit driving device 1, first operate the controller 28 to control the first driving motor 14 to rotate. When the first driving motor 14 rotates, it will drive the transmission rod 4 to rotate synchronously. When the transmission rod 4 rotates, it will drive the first transmission gear 13 and the second transmission gear 21 on the outer surfaces of both ends to rotate synchronously. When the first transmission gear 13 and the second transmission gear 21 rotate, they will move on the upper surface of the walking rail 3 through the transmission tooth grooves 34. When the first transmission gear 13 and the second transmission gear 21 move, they will drive the limit driving device 1 to move on the upper surface of the walking rail 3 through the arc-shaped clamping rods 11 until the limit driving device 1 is moved to other positions in the tunnel and it is convenient for the staff to repair the crack. Then, continue to control the pump 9 to operate to transport the material inside the storage cylinder 10 into the grouting nozzle 25 and inject it into the crack. Therefore, by controlling the operation of the limit driving device 1 and the support device 2, it is possible to facilitate continuous track walking repair of the inner surface of the tunnel, and it is convenient for the staff to repair the crack close to the inner arc surface of the tunnel, thereby improving the efficiency of repairing the inner surface of the tunnel.

The tool storage box 37 is fixedly installed on one side edge of the support base 29, and hooks 38 are evenly and fixedly connected to the outer surface of the upper part of the tool storage box 37.

[0054] When implementing this embodiment, by providing the limiting frames 36, the tool storage box 37 and the hooks 38 on the upper surface of the support base 29, it is convenient for the staff to carry tools on the upper surface of the support base 29. At the same time, the limiting frames 36 can provide safety protection for the staff.
