[0013] The application will be further described in detail below in combination with embodiments, and the embodiments are exemplary and are intended to explain the application, and cannot be understood as limiting the application.
[0014] The cable strand of the rotary main cable is pushed into the saddle: the cable strand is pushed into the saddle in the following order: synchronous pushing into the saddle of the main tower cable saddle and the rotary main saddle, pushing into the saddle of the rotary side turning cable saddle, and pushing into the saddle of the scattered cable saddle.
[0015] The strand at the rotary main saddle is made by bending pre-forming and shaping technology. In order to ensure the quality of the strand entering the saddle horizontally, the horizontal pushing device is used to control the strand not to appear the phenomenon of drum silk and scattered silk. The vertical track of the horizontal pushing device is installed on the inner wall of the corresponding annular channel (i.e. annular anchor way) of the rotary main saddle in advance. The electric push rod is installed on the vertical track to adjust the vertical position of the horizontal pushing device by moving up and down. The front end of the electric push rod is installed with a supporting ring to act on the main cable strand. The pushing force of the electric push rod realizes the horizontal entering of the strand into the saddle.
[0016] The marked point on the strand should be accurately aligned with the marked point at the saddle when entering the saddle. The rotary main saddle is horizontally entered from the middle to both sides of the saddle. When the strand is transversely moved above the annular channel, the strand is lowered to the height position to be installed. The height of the horizontal pushing device of the strand is adjusted. The supporting ring at the head of the push rod is tightly attached to the strand. The strand is pushed into the specified position of the cable groove of the saddle by the pushing force of the electric push rod. After the marked point on the strand is aligned with the center point of the saddle, the wedge is tightly wedged.
[0017] The horizontal pushing device is arranged on the outer inner wall of the annular anchor way 3. The rotary main saddle 2 is arranged on the inner inner wall of the annular anchor way 3. The horizontal pushing device 1 is horizontally opposite to the rotary main saddle 2. The horizontal pushing device 1 includes a vertical sliding rail 104, a sliding block 103, an electric push rod 101, a supporting ring 102 and a pull rope 105. The vertical sliding rail 104 is fixed on the inner wall of the annular anchor way 3. The sliding block 103 is arranged at the rear end of the electric push rod 101. The sliding block 103 is in sliding cooperation with the vertical sliding rail 104. The electric push rod 101 moves up and down along the vertical sliding rail 104 to adjust the height. One end of the pull rope 105 is connected with the electric push rod 101. The other end of the pull rope 105 is connected with the inner wall of the annular anchor way 3 to stabilize the horizontal state of the electric push rod. The supporting ring 102 is arranged at the front end of the electric push rod 101. The supporting ring 102 is used to support the strand. The strand is pushed into the corresponding cable groove of the rotary main saddle 2 by the horizontal extension action of the electric push rod.
[0018] The entering sequence of the rotary cable saddle is as follows: after the entering of the strand into the rotary main saddle is completed, the entering of the strand into the rotary cable saddle on both sides of the upstream and downstream is performed. The entering direction of the strand into the rotary cable saddle is from the side span to the middle span. The horizontal chain is used to adjust the entering of the strand into the saddle groove. After the marked point on the strand is aligned with the center point of the saddle, the wedge is tightly wedged.
[0019] The entering direction of the tower top main saddle is as follows: the tower top saddle part is from the side span to the middle span. The position of the red silk of the strand in the saddle is strictly controlled to prevent the twisting of the strand. The two hooks on the tower top portal are simultaneously and gently lowered to put the strand into the specified position of the cable groove of the saddle. After the marked point on the strand is aligned with the mark of the saddle, the wedge is tightly wedged.
