The pulleys are distributed inside the first guide rail and the second guide rail and are used to connect the slide rail assembly and the fixed frame to define the moving tracks of the fixed frame and the support plate.

5. A construction method for a deep inclined shaft excavation and support device, characterized in that, Adopt the deep inclined shaft excavation and support device according to any one of claims 1-4. The construction method of the deep inclined shaft excavation and support device includes the following steps: laying the slide rail assembly on the inner wall of the deep inclined shaft, fixing the slide rail assembly to fit the inner wall of the deep inclined shaft, driving the steel structure platform to move along the slide rail assembly through the hoisting winch and the steel wire rope, making the steel structure platform always in a horizontal state during the movement through the connection assembly, and fixing the position of the steel structure platform inside the deep inclined shaft through the positioning assembly.
