DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The present application embodiment discloses a movable omnidirectional tunnel repair ladder. Figure 1-3 The movable all-round tunnel repair ladder includes a moving vehicle 1 and an escalator 2, and the bottom of the escalator 2 is hinged to the moving vehicle 1. The moving vehicle 1 can be a hand-pushed type or a driving type, which can be selected according to actual conditions. The moving vehicle 1 is pushed or driven into the position to be repaired in the tunnel 7 along the axial direction of the tunnel 7. When the position to be repaired is higher, the escalator 2 is rotated, and the top of the escalator 2 is overlapped on the inner wall of the tunnel 7. The staff climbs up the escalator 2, stands at the height of the position to be repaired, and repairs the position to be repaired, thereby facilitating all-round repair of the interior of the tunnel 7.

[0033] Reference Figure 1-3 The escalator 2 is composed of a plurality of unit ladders 21. A connection groove 22 is provided at the top of the unit ladder 21. A connection column 23 is fixedly connected to the bottom of the unit ladder 21. The connection column 23 is inserted into the connection groove 22 of the adjacent unit ladder 21 and fixed by screws. On the one hand, the escalator 2 can be disassembled into a plurality of unit ladders 21, placed on the mobile vehicle 1 and pushed into the tunnel 7 for splicing and assembly, which is convenient for the movement and transportation of the escalator 2; on the other hand, the number of spliced ​​unit ladders 21 can be selected according to the size of the tunnel 7, so as to adapt to the repair of tunnels 7 of different sizes. The connection groove 22 runs through the side wall of the unit ladder 21, and the connection column 23 penetrates into the connection groove 22 of the adjacent unit ladder 21 from the same side of the unit ladder 21. When the adjacent unit ladders 21 are connected, it is not necessary to insert the connection column 23 into the connection groove 22 from the top, but the connection column 23 can also be moved to the connection groove 22 from the side, which is more convenient to operate. A storage box 24 is fixedly installed on the mobile vehicle 1, and the storage box 24 is used to store the disassembled unit ladder 21. The disassembled unit ladder 21 can be placed in the storage box 24, which is stable and easy to transport.

[0034] Reference Figure 1-3 The unit ladder 21 includes a cross bar 25, a first side bar 26 and a second side bar 27. The side walls of the middle of the first side bar 26 and the second side bar 27 are respectively provided with a first connection hole 261 and a second connection hole 271. One end of the cross bar 25 passes through the first connection hole 261, and the end of the cross bar 25 passing through the first connection hole 261 is fixedly connected to the limit cap 3. The size of the limit cap 3 is larger than the size of the first connection hole 261. The other end of the cross bar 25 passes through the second connection hole 271 and is fixed to the second side bar 27 by a fixing bolt 4. The connecting groove 22 is provided at the top of the first side bar 26 and the second side bar 27, and the connecting column 23 is fixedly connected to the bottom of the first side bar 26 and the second side bar 27. The unit ladder 21 is detachable, and the cross bar 25, the first side bar 26 and the second side bar 27 can be processed separately. When the unit ladder 21 is assembled and fixed, it is only necessary to fix the end of the cross bar 25 away from the limit cap 3 by fixing screws. The operation is convenient and the amount of screws can be reduced, saving installation time.

[0035] Reference Figure 1-3The cross bar 25 is a square bar, which helps to improve the stability of the staff standing on the cross bar 25. A receiving groove 262 is provided on the side wall of the first side bar 26, and the receiving groove 262 is connected to the first connecting hole 261, and the limiting cap 3 is embedded in the receiving groove 262. The limiting cap 3 is embedded in the receiving groove 262, which can make the outer wall of the first side bar 26 flat, and it is not easy to be scratched when the staff holds it with their hands, thereby improving the safety of use.

[0036] Reference Figure 1-3 The second connection hole 271 includes an inner hole 5 and an outer hole 6 that are interconnected. The outer hole 6 is closer to the outer side of the second side rod 27 than the inner hole 5, and the size of the outer hole 6 is smaller than that of the inner hole 5. The end of the cross bar 25 away from the limiting cap 3 is inserted into the inner hole 5. The rod diameter of the fixing bolt 4 is adapted to the outer hole 6. The fixing bolt 4 passes through the outer hole 6 and then extends into the inner hole 5 to be threadedly connected with the cross bar 25. The fixing bolt 4 of a generally smaller size can be used to fix the cross bar 25 in a direction perpendicular to the outer wall of the second side rod 27, which saves costs and is easy to operate.

[0037] The implementation principle of the movable all-round tunnel repair ladder in the embodiment of the present application is as follows: the mobile vehicle 1 can be a hand-pushed type or a driving type, which can be selected according to the actual situation. The mobile vehicle 1 is pushed or driven into the position to be repaired in the tunnel 7 along the axial direction of the tunnel 7. When the position to be repaired is relatively high, the escalator 2 is rotated, and the top of the escalator 2 is overlapped on the inner wall of the tunnel 7. The staff climbs up the escalator 2, stands at the height of the position to be repaired, and repairs the position to be repaired, thereby facilitating all-round repair of the interior of the tunnel 7.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
