[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0016] like Figure 1-Figure 2 As shown, a rotary prestressed steel strand threading platform device includes a load-bearing bracket 1, a rotating support row 2 is installed on the top of the load-bearing bracket 1, and a rotating mechanism for driving the rotating support row 2 to rotate is installed on the load-bearing bracket 1. The rotating mechanism includes an installation box 8 arranged at the bottom center of the load-bearing bracket 1, and a motor for driving the rotating support row 2 to rotate is provided in the installation box 8.

[0017] A winch 3 is installed on one side of the top of the rotating support row 2, and a wire rope guide bracket 4 is installed on the other side. The wire rope 5 on the winch 4 is guided by the wire rope guide bracket 4. The wire rope guide bracket 4 includes a vertical pole 41, a horizontal pole 42, and an oblique pole 43. One end of the horizontal pole 42 is vertically fixed to the top of the vertical pole 41, and the oblique pole 43 is connected to the angle between the vertical pole 41 and the horizontal pole 42. Guide wheels 44 are installed on the lower part of the vertical pole 41, the intersection of the vertical pole 41 and the horizontal pole 42, and the end of the horizontal pole 42. The wire rope 5 is guided from bottom to top by the guide wheel 44, and the prestressed steel strand 6 is connected and fixed to the wire rope 5 through a joint.

[0018] The load-bearing bracket 1 is installed on the top of the concrete tower 7. Lifting ears 9 are provided at both ends of the top of the load-bearing bracket 1. A fixing mechanism is provided between the load-bearing bracket 1 and the concrete tower 7. The fixing mechanism includes an electric push rod 10 arranged on both sides of the mounting box 8.
