[0023] The traditional steel bar welded ladder device has many shortcomings in the construction of the starting section of the inclined shaft TBM. First, due to the large slope of the inclined shaft, the traditional ladder is heavy and difficult to climb, which brings great inconvenience to the construction workers. Secondly, the traditional ladder consumes a lot of steel, which not only increases the construction cost, but also brings many difficulties during transportation and welding.

[0026] The ladder unit is short in length, and each ladder unit has the same structure and can be produced uniformly. Components in the same parts are universal for easy processing and transportation. The ladder is configured as a combination of multiple ladder units, so that the length of the ladder device can be easily extended. The angle of a single ladder unit can be adjusted according to the actual situation of the slope of the inclined shaft, thereby improving the flexibility of the device and making the ladder suitable for a variety of environments. Exemplarily, in this embodiment, when the angle between the ladder unit located at the bottom of the slope and the horizontal plane is 15°, for the convenience of description, it is called the first ladder unit, and the ladder unit connected to the ladder unit is called the second ladder unit, and the angle between the second ladder unit and the horizontal plane is 15°. The specific implementation method is: the first ladder unit and the second ladder unit are connected by a ladder connector 4, and the ladder connector 4 includes a rotating shaft and two connecting rods connected to the rotating shaft. The connecting rods rotate relative to the rotating shaft. One connecting rod connects the first ladder unit, and the other connecting rod connects the second ladder unit. Because the two connecting rods can rotate relative to the rotating shaft, the angle between the two connecting rods can be adjusted, and then the angle between the first ladder unit and the second ladder unit can be adjusted, thereby realizing the adjustment of the ladder device, making the ladder device flexible, and when the slope of the inclined shaft is uneven, the ladder device provided by the present application can adjust the angle, so that installation is more convenient and construction efficiency is improved.
