[0009] A special-shaped cover, which is arranged on the side of the U-shaped cover away from the connecting plate. One end of the special-shaped cover is connected to the U-shaped cover, and the other end of the U-shaped cover is connected to the top cover.

[0010] Further, a bracket is arranged at the bottom of the U-shaped cover, and the bracket is connected to the bottom plane of the U-shaped cover.

[0011] Further, the top of the bracket is a plane, and a bolt hole is arranged at the top of the bracket. The bottom of the U-shaped cover is a plane, and a bolt hole is arranged at the bottom of the U-shaped cover. The two bolt holes are connected by bolts.

[0012] Further, a short connecting plate is arranged on the side of the top cover close to the special-shaped cover. The short connecting plate is connected to the special-shaped cover by screws, and the short connecting plate is fixedly connected to the top cover.

[0013] As can be seen from the above technical solutions, compared with the prior art, the present utility model discloses a speed limiter rope wheel protective cover. By providing a U-shaped cover, a top cover, and a special-shaped cover, all-round protection of the speed limiter rope wheel can be achieved. At the same time, by providing the special-shaped cover, the shape of the special-shaped cover can be changed according to the shape of the speed limiter rope wheel during use, and thus it can be applicable to the shapes of various speed limiter rope wheels.
