[0002] To achieve 180° rotation of the main cable of a swing cable suspension bridge, a corresponding cable saddle system must be provided to meet the demands of internal force transmission between the main cable and the anchorage and spatial displacement of the main cable. A traditional cable saddle system is composed of two rotating cable saddles installed symmetrically on both sides of the cable turning passage and one main cable saddle installed at the top of the cable turning passage. Specifically, the rotating cable saddles are fixed to the sides of both sides of the anchorage structure inside the cable turning passage. Specifically, the main cable saddle is fixed to the side of the top of the anchorage structure inside the cable turning passage. Both the rotating cable saddles and the main cable saddle are in a horizontal position, and the horizontal steering and support of the main cable are achieved through notches installed laterally on the cable saddle body. However, while the traditional main cable horizontal turning system solves the problem of main cable turning, it also causes stress concentration on the cable saddle body and anchorage structure.

[0010] The cable horizontal swing anchorage system is provided at the ends of the suspension bridge along the bridge longitudinal direction, and for clarity, as currently defined, the farthest end of cable swing path 1 from the suspension bridge along the bridge longitudinal direction is the top of cable swing path 1, and the farthest end of anchorage structure 2 from the suspension bridge along the bridge longitudinal direction is the top of anchorage structure 2.
[0011] The cable horizontal rotation anchorage system and construction method of the present invention will be described in more detail below in conjunction with FIGS. 1 to 7. FIG.
[0012] A cable horizontal pivot anchorage system including an anchorage structure (2), a rotating cable saddle (10), a main cable saddle, and a branch cable saddle (9), The anchorage structure 2 has a cable turning passage 1, and the rotating cable saddles 10 are symmetrically distributed on both sides of the cable turning passage 1. The main cable saddle is provided on the central axis of the top part of the cable turning passage 1. The branching cable saddles 9 are fixedly provided on the top part of the cable turning passage 1 and are symmetrically distributed along the main cable saddle. The main cable saddle includes a first main cable saddle 6 and a second main cable saddle 7, and a notch 16 of the main cable saddle and a notch 16 of the second main cable saddle 7 are provided back to back along the central axial direction of the top part of the cable turning passage 1, and the first main cable saddle 6 and the second main cable saddle 7 are connected in the axial direction by a force transmission mechanism 8, The force transmission mechanism 8 is fixed to the cable turning passage 1, and the branch cable saddle 9 includes a cable saddle body 14, The cable includes a first cable 4 and a second cable 5, a first main cable saddle 6 is used for turning the first cable 4 in an inverted U-shape at the top of the cable turning passage 1, and a second main cable saddle 7 and a branch cable saddle 9 are used for turning the second cable 5 in an M-shape at the top of the cable turning passage 1. Cable horizontal slewing anchorage system.
[0013] The rotating cable saddle 10, the main cable saddle, and the branch cable saddle 9 are all provided in a lying state in the cable turning passage 1, and each of the rotating cable saddle 10, the main cable saddle, and the branch cable saddle 9 includes a cable saddle body 14 and a grille 15. A notch 16 is opened laterally at one horizontal end of the cable saddle body 14, and the twisting cable saddles 10 and the branching cable saddles 9 are fixed to the anchorage structure 2 inside the cable turning passage 1. Specifically, the grilles 15 of the twisting cable saddles 10 are pre-embedded on both side surfaces of the anchorage structure 2 inside the cable turning passage 1, and the grilles 15 of the branching cable saddles 9 are pre-embedded on the side surfaces of the top part of the anchorage structure 2 inside the cable turning passage 1 and are distributed symmetrically on the main cable saddle. The twisting cable saddles 10 and the branching cable saddles 9 are each fixed to the anchorage structure 2 inside the cable turning passage 1 via the pre-embedded grilles 15, but the branching cable saddle 9 is located between the first main cable saddle 6 and the second main cable saddle 7 along the longitudinal direction of the bridge. The force transmission mechanism 8 is fixed to the top surface of the anchorage structure 2 below the top part of the cable turning passage 1, and the first main cable saddle 6 and the second main cable saddle 7 are provided on the top surface of the anchorage structure 2 below the top part of the cable turning passage 1 and abut against the force transmission mechanism 8 via their respective grilles 15. The notches 16 of the rotating cable saddle 10, the branching cable saddle 9 and the first main cable saddle 6 face outward from the cable turning passage 1, and the notch 16 of the second main cable saddle 7 faces inward from the cable turning passage 1, but the notches 16 of the first main cable saddle 6 and the second main cable saddle 7 are provided back-to-back along the central axis of the top part of the cable turning passage 1.Specifically, the cable turning passage 1 has an inverted U-shaped structure. After passing horizontally through the notch 16 of the twisting cable saddle 10 on one side of the cable turning passage 1, the cable branches off into the first cable 4 and the second cable 5 at a certain rate. The first cable 4 forms an inverted U-shape horizontally and passes through the notch 16 of the first main cable saddle 6 before completing its turn at the top of the cable turning passage 1. The second cable 5 forms an M-shape horizontally and passes through the notch 16 of the branch cable saddle 9 on the same side, the notch 16 of the second main cable saddle 7, and the notch 16 of the branch cable saddle 9 on the other side of the second main cable saddle 7, before completing its turn at the top of the cable turning passage 1. After the first cable 4 and the second cable 5 have completed their turns, they merge and then the whole passes through the twisting cable saddle 10 on the other side of the cable turning passage 1.
[0014] The force transmission mechanism 8 has a rectangular frame structure and includes transmission levers arranged to cross horizontally, a pressure plate wrapped around the outside of the transmission levers, and a grill 15. The grill 15 is embedded in advance in the top surface of the anchorage structure 2 below the top part of the cable turning passage 1, and the force transmission mechanism 8 is fixed between the first main cable saddle 6 and the second main cable saddle 7 by bolting the pressure plate to the grill 15. The first main cable saddle 6 and the second main cable saddle 7 are abutted against the pressure plates of the force transmission mechanism 8 at corresponding positions via their respective grills 15.
[0015] The cables are branched into a first cable 4 and a second cable 5, with the first cable 4 curved in an inverted U-shape around the central axis of the top of the cable curve passage 1, and the second cable 5 curved in an M-shape around the top of the cable curve passage 1. Specifically, the second cable 5 interacts with the first cable 4 at the central axis of the cable curve passage 1, curved in a U-shape, thereby reducing the longitudinal bridge force that the first cable 4 applies to the anchorage structure 2 via the force transmission mechanism 8. This avoids the stress concentration at the central axis of the top of the cable curve passage 1 that occurs in traditional cable saddle systems. Furthermore, as can be seen from the force analysis, the longitudinal bridge force of the first cable 4, which is reduced at the central axis of the top of the cable curve passage 1, is correspondingly distributed to the branch cable saddle 9, i.e., the longitudinal bridge force of the second cable 5 on the inner anchorage structure 2 at both sides of the top of the cable curve passage 1, is increased. In summary, with the above settings, the stress at the central axis of the top part of the anchorage structure 2 can be distributed to both sides of the top part of the anchorage structure 2, avoiding stress concentration at the central axis of the top part of the anchorage structure 2. Furthermore, by adjusting the distribution ratio of the first cable 4 and the second cable 5, the degree to which the second cable 5 reduces the bridge longitudinal force of the first cable 4 and the magnitude of the stress distributed up to the branch cable saddle 9 can be adjusted. Specifically, it is possible to achieve uniform load bearing in the longitudinal direction of the bridge for the anchorage structure 2, so that the bridge longitudinal force at the central axis of the top part of the anchorage structure 2 and the bridge longitudinal force at both sides of the top part of the anchorage structure 2 are the same, thereby significantly reducing the difficulty of designing the anchorage structure 2. On the other hand, the inverted U-shaped winding of the first cable 4 and the M-shaped winding of the second cable 5 are compatible with the structure of the notch 16 of the traditional main cable saddle and branch cable saddle 9, eliminating the need to specially customize the cable saddle body 14 and preventing stress concentration on the main cable saddle and branch cable saddle 9 due to the cables.
[0016] The main cable saddle, the rotating cable saddle 10, further has a grill 15 pre-embedded in the top surface of the anchorage structure 2 below the cable turning passage 1, and the cable saddle body 14 of the rotating cable saddle 10, the grill 15 pre-embedded in the top surface of the anchorage structure 2 below the cable turning passage 1, and the grills 15 pre-embedded in the side surfaces on both sides of the anchorage structure 2 inside the cable turning passage 1 are slidably connected via friction pairs 28 so as to limit the position along the cable turning direction, and the friction pairs 28 are polytetrafluoroethylene plates.
[0017] The anchorage system further includes a cable anchorage device 3 fixedly mounted in the cable turning passage 1 .
[0018] The two cable fixing devices 3 are distributed symmetrically in the cable turning passage 1, and specifically, along the cable turning direction, the first cable fixing device 3 is fixedly installed on the upstream side of the rotating cable saddle 10 on the same side, and the other cable fixing device 3 is fixedly installed on the downstream side of the rotating cable saddle 10 on the same side.
[0019] By fixing the cable with the cable fixing device 3, the height and horizontal position of the cable entering and exiting the saddle can be made to match the design, thereby realizing linear control of the cable entering and exiting process, improving the linear fluency of the cable turning, and avoiding the occurrence of non-designed linear bending, which will affect the stress distribution and cause further stress concentration.
[0020] The cable fixing device 3 includes a fixed frame 20 and a clamping portion, the clamping portion being slidably connected to the fixed frame 20, and the fixed frame 20 being fixed to the cable turning passage 1; The clamping unit includes a first jig 23, a second jig 24, and a third jig 25 arranged crosswise, the first jig 23 is connected to the fixed frame 20 in a slidable manner along the vertical direction, the second jig 24 and the third jig 25 are distributed symmetrically on both sides of the first jig 23, and are connected to the fixed frame 20 in a slidable manner along the direction inclined to the first jig 23, Between the first jig 23 and the second jig 24 and the third jig 25, there is provided a linkage mechanism for simultaneously sliding the first jig 23, the second jig 24 and the third jig 25 in a direction closer to the cable.
[0021] The first jig 23, the second jig 24, and the third jig 25 are all rod-shaped structures, one end of which is slidably connected to the fixed frame 20 via a position limiting groove 27, and the other end is provided with a chuck 26. The chucks 26 of the first jig 23, the second jig 24, and the third jig 25 clamp the cable in three circumferential directions. The first jig 23 is provided perpendicular to the center line of the bottom of the cable, and the second jig 24 and the third jig 25 are provided symmetrically on both sides of the first jig 23. The second jig 24 and the third jig 25 both extend in a direction inclined toward the first jig 23 and rotate toward the cable after exceeding a certain distance from the first jig 23. The interlocking mechanism has a structure in which gears 21 and racks 22 are fitted together. The gears 21 are symmetrically arranged on both sides of the fixed frame 20 of the first jig 23 near one end thereof. The first jig 23, the second jig 24, and the third jig 25 all have a single-stage rack 22 at a position corresponding to the gear 21. When the power unit drives the first jig 23 to approach the bottom of the cable vertically, the rack 22 of the first jig 23 rotates the gears 21 on both sides. With the gears 21 and the racks 22 of the second jig 24 and the third jig 25 fitted together, the second jig 24 and the third jig 25 move downward, further bringing their chucks 26 closer to the cable, ultimately forming a three-way clamp around the cable circumference.
[0022] By providing an interlocking mechanism, the movement of the first jig 23 drives the coordinated movement of the second jig 24 and the third jig 25, thereby realizing high-speed clamping of the cable. The structure is simple and easy to operate, and at the same time the three-way clamping structure is stable, greatly improving the cable fixing speed and fixing effect.
[0023] A first adjustment mechanism 11 is provided between the first main cable saddle 6, the second main cable saddle 7 and the force transmission mechanism 8 for adjusting the distance between the first main cable saddle 6, the second main cable saddle 7 and the force transmission mechanism 8.
[0024] The first adjustment mechanism 11 is provided along the longitudinal direction of the bridge between the grill 15 of the first main cable saddle 6 and the pressure plate corresponding to the force transmission mechanism 8, and between the grill 15 of the second main cable saddle 7 and the pressure plate corresponding to the force transmission mechanism 8.
[0025] The force acting opposite to that of the first cable 4, which the second cable 5 applies to the anchorage structure 2 in the central axis direction of the top part of the cable turning passage 1 through the force transmission mechanism 8, is related to the branching ratio of the second cable 5 as well as the horizontal relative position of the branching cable saddle 9 and the second main cable saddle 7. The distance between the first main cable saddle 6, the second main cable saddle 7 and the force transmission mechanism 8 is adjusted through the first adjustment mechanism 11, while the longitudinal force of the first cable 4 applied by the second cable 5 is This allows for adjustment of the reduction state, and even after the cable rotation is completed, it is possible to achieve secondary fine adjustment of the force distribution of the anchorage structure 2 according to the actual construction situation. Meanwhile, the rotation linearity of the first cable 4 and the second cable 5 can be further adjusted to match the notch 16 structure of the cable saddle body 14 as much as possible. The cables are always tangent to the notch 16 when entering and leaving the saddle, ensuring smooth rotation of the entire cable and avoiding stress concentration on the cable saddle body 14.
[0026] A grill 15 is further embedded in advance in the anchorage structure 2 below the main cable saddle, and the cable saddle body 14 of the main cable saddle is slidably connected to the grill 15 embedded in advance in the anchorage structure 2 below the main cable saddle along the central axis direction of the top part of the cable turning passage 1.
[0027] The main cable saddle further has a grille 15 embedded in advance in the top surface of the anchorage structure 2 below the cable turning passage 1, and the cable saddle body 14 of the main cable saddle and the grille 15 embedded in advance in the top surface of the anchorage structure 2 below the cable turning passage 1 are connected via a friction pair 28 so as to slide in the direction of the central axis of the top part of the cable turning passage 1. The friction pair 28 is a polytetrafluoroethylene plate, and reduces the friction force between the first main cable saddle 6 and the second main cable saddle 7 and the anchorage structure 2 below the cable turning passage 1 when they move, making it easier to adjust the pitch of the first adjustment mechanism 11. A position limiting block 29 is also provided to prevent the main cable saddle from moving out of the direction of the central axis of the top part of the cable turning passage 1.
[0028] The first adjustment mechanism 11 includes a mounting plate 17 and a damper hinge 19, one side of which is fixed to the first main cable saddle 6 and the second main cable saddle 7, and the other side of which is connected to the damper hinge 19 so as to be rotatable in the axial direction.
[0029] The damper hinge 19 includes a rotation shaft and hinge plates rotatably mounted on both sides of the rotation shaft. One side of the mounting plate 17 is attached to the grilles 15 of the first main cable saddle 6 and the second main cable saddle 7 by bolts along the longitudinal direction of the bridge, and the rotation shaft of the damper hinge 19 is fixedly mounted on the other side of the mounting plate 17, and the hinge plates of the damper hinge 19 abut against the force transmission mechanism 8. The damper hinge 19 and the mounting plate 17 are axially rotatable, so that the force-receiving rotation of the damper hinge 19 can adjust the distance between the first main cable saddle 6, the second main cable saddle 7 and the force transmission mechanism 8. Meanwhile, when the damper hinge 19 rotates, it generates a reaction force against the bridge longitudinal force of the first main cable saddle 6, the second main cable saddle 7, and the rotation angle has a positive correlation, which reduces the pressure received by the force transmission mechanism 8 and further reduces the bridge longitudinal force applied to the main cable saddle by the force transmission mechanism 8 at the central axis position of the cable rotation passage 1, thereby reducing the overall force received by the anchorage structure 2. The damper hinge 19 can realize self-adaptation to the interaction between the first cable 4 and the second cable 5, and can perform self-adaptive adjustment of the cable line shape.
[0030] The first adjustment mechanism 11 includes a toothed plate 18, which is fixed to the force transmission mechanism 8 to limit the axial rotation of the damper hinge 19; The hinge plate of the damper hinge 19 is extendable and contractible in the axial direction.
[0031] In order to ensure that the distance between the first main cable saddle 6, the second main cable saddle 7 and the force transmission mechanism 8 can be controlled, the pressure receiving plate at the corresponding position of the force transmission mechanism 8 is further provided with a tooth plate 18 to engage with the hinge plate of the damper hinge 19 in a limited manner. In actual use, the hinge plate is first contracted in the axial direction, adjusted and rotated to an appropriate angle, and then extended in the axial direction again to abut against the tooth plate 18 and limit the position.
[0032] The branch cable saddle 9 includes a second adjustment mechanism 12 for adjusting the angle between the cable saddle body 14 of the branch cable saddle 9 and the anchorage structure 2 inside the cable turning passage 1, and the branch cable saddle 9 is fixed to the top part of the cable turning passage 1 by the second adjustment mechanism 12.
[0033] The branch cable saddle 9 includes a cable saddle body 14, a second adjustment mechanism 12, and a grille 15. The second adjustment mechanism 12 is located at a central position between the cable saddle body 14 and the grille 15, which is pre-embedded in the side of the top part of the anchorage structure 2 inside the cable turning passage 1. The second adjustment mechanism 12 is fixed to the cable saddle body 14 and the grille 15. When turning the second cable 5, the angle between the cable saddle body 14 and the anchorage structure 2 inside the cable turning passage 1 can be adjusted via the second adjustment mechanism 12 to fit the notch 16 structure of the cable saddle body 14 of the branch cable saddle 9 as much as possible. The second cable 5 is always tangent to the notch 16 of the branch cable saddle 9 when entering and leaving the saddle, ensuring smooth turning of the entire second cable 5 and avoiding stress concentration on the cable saddle body 14.
[0034] The diverter cable saddle 9 includes a buffer mechanism 13 provided between a cable saddle body 14 of the diverter cable saddle 9 and an anchorage structure 2 inside the cable turning passage 1 .
[0035] The branch cable saddle 9 includes a cable saddle body 14, a buffer mechanism 13, and a grille 15. The buffer mechanism 13 is a high-strength spring that is uniformly distributed at the four corners between the cable saddle body 14 and the grille 15, which is pre-embedded in the side of the top part of the anchorage structure 2 inside the cable turning passage 1. When the cable turns, the elastic deformation of the high-strength spring reduces the bridge longitudinal force that the second cable 5 applies to the anchorage structure 2 at both sides of the top part of the cable turning passage 1, and further reduces the force received by the entire anchorage structure 2.
[0036] The second adjustment mechanism 12 includes a base, a link, and a connecting plate, the base and the connecting plate being fixed to the anchorage structure 2 inside the cable swivel passage 1 and the cable saddle body 14, respectively, and the link having one end swingably connected to the base and the other end fixed to the connecting plate.
[0037] The base and the connecting plate are respectively connected by bolts to the grille 15 and the cable saddle body 14, which are embedded beforehand in the side of the top part of the anchorage structure 2 inside the cable turning passage 1. One end of the link is connected to the base in a horizontal direction so as to be able to swing, and the other end is welded and fixed to the connecting plate.
[0038] In another embodiment, in order to increase the smoothness of the swinging of the second adjustment mechanism 12, the branch cable saddle 9 further has a grill 15 pre-embedded in the top surface of the anchorage structure 2 below the cable turning passage 1, and the cable saddle body 14 of the branch cable saddle 9 and the grill 15 pre-embedded in the top surface of the anchorage structure 2 below the cable turning passage 1 are slidably connected via a friction pair 28, and the friction pair 28 is a polytetrafluoroethylene plate.
