[0002] With the development of national infrastructure, large-span bridges continue to emerge. As a structure with strong spanning capacity, cable-stayed bridges are increasingly used across rivers, lakes, seas, and mountain valleys. The installation of the cable-stayed cable is a major difficulty in the construction process of the cable-stayed bridge. The construction control is difficult and the safety risk is high. In the past, soft slings or hoops were used to tie the cable-stayed cables, and the winches were used to pull the cable-stayed cables to the beam ends. However, soft slings or hoops can only be pulled to the cable guide pipe outlet at the beam end, which affects the construction progress and often damages the surface PE of the cable-stayed cable, affecting the quality of the cable body.

[0005] The traction lining is symmetrically provided with lifting ears, and the lifting ears are respectively provided with ear holes.
[0006] The traction bushing comprises an upper cover plate and a lower cover plate, and the upper cover plate and the lower cover plate are relatively combined and fixedly connected by connecting bolts.

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0018] like Figure 1 , 2 As shown in Figures 3 and 4, a fast traction tool for a cable in this embodiment includes a traction bushing, and end plates 1 are respectively provided at both ends of the traction bushing, and cable holes are respectively provided in the center of the end plates 1, so that the traction bushing surrounds the outer periphery of the cable 9. One end of the cable 9 is anchored in the anchor cup 8, and an end plate 1 close to the anchor cup 8 is against the end of the anchor cup 8, so that it is subjected to force at the end of the anchor cup. Lifting ears 4 are symmetrically provided on the traction bushing, and ear holes 5 are respectively provided on the lifting ears 4 to facilitate the connection of the traction rope and the traction bushing.
[0019] The traction bushing includes an upper cover plate 6 and a lower cover plate 7 , which are relatively combined and fixedly connected by connecting bolts 3 .
[0020] The upper cover plate 6 and the lower cover plate 7 are both Ω-shaped. A plurality of C-shaped reinforcing plates 2 are arranged on the upper cover plate 6 and the lower cover plate 7, and the plurality of reinforcing plates 2 are evenly spaced along the length direction of the upper cover plate 6 and the lower cover plate 7.
[0021] The length of the traction bushing can be customized according to the length of the cable guide tube at the beam end. The outer diameter of the traction bushing is smaller than the outer diameter of the anchor cup, which makes it easier to pull the traction bushing into the cable guide tube at the beam end until it is anchored. The inner diameter of the traction bushing is larger than the outer diameter of the connecting tube of the anchor cup of the inclined cable. After the beam end is anchored, the traction bushing can be directly pulled out of the cable guide tube at the beam end.
[0022] like Figure 5As shown, the winch directly pulls the liner, and the end face of the liner in contact with the anchor cup directly acts on the end of the anchor cup of the inclined cable. The force surface during traction is on the end face of the anchor cup, and will not have any impact on the cable body. The length of the liner can be customized according to the length of the cable guide tube at the beam end. The outer diameter of the liner is smaller than the outer diameter of the anchor cup, which facilitates the liner to be pulled into the cable guide tube at the beam end until it is anchored. The inner diameter of the liner is larger than the outer diameter of the connecting tube of the inclined cable anchor cup. After the beam end is anchored, the liner can be directly pulled out of the cable guide tube at the beam end.
[0023] The force-bearing surface of the traction bushing of the present application is at the end surface of the anchor cup during traction, thereby avoiding damage to the cable body of the inclined cable; the traction bushing can be pulled into the cable guide tube at the end of the beam, thereby improving construction efficiency.
[0024] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
