Best Mode for Carrying Out the Invention

[0010] The cable horizontal slewing anchorage system is provided at the end of the suspension bridge along the longitudinal direction of the bridge. For the sake of clear explanation, as currently defined, the farthest end from the suspension bridge along the longitudinal direction of the cable slewing passage 1 is the top part of the cable slewing passage 1, and the farthest end from the suspension bridge along the longitudinal direction of the anchorage structure 2 is the top part of the anchorage structure 2.

[0011] Hereinafter, the cable horizontal slewing anchorage system and construction method of the present application will be described in more detail in combination with FIGS. 1 to 7.

[0012] A cable horizontal slewing anchorage system including an anchorage structure 2, a rotating cable saddle 10, a main cable saddle, and a shunt cable saddle 9, The anchorage structure 2 is provided with a cable slewing passage 1. The rotating cable saddles 10 are symmetrically distributed on both sides of the cable slewing passage 1. The main cable saddle is provided on the central axis of the top part of the cable slewing passage 1. The shunt cable saddle 9 is fixedly provided on the top part of the cable slewing passage 1 and is 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. The notches 16 of the main cable saddle and the notches 16 of the second main cable saddle 7 are provided facing away from each other along the central axis direction of the top part of the cable slewing passage 1. The first main cable saddle 6 and the second main cable saddle 7 are axially connected by a force transmission mechanism 8. The force transmission mechanism 8 is fixedly provided in the cable slewing passage 1. The shunt cable saddle 9 includes a cable saddle body 14. The cable includes a first cable 4 and a second cable 5. The first main cable saddle 6 is used for the reverse U-shaped turning of the first cable 4 at the top of the cable turning passage 1. The second main cable saddle 7 and the shunt cable saddle 9 are used for the M-shaped turning of the second cable 5 at the top of the cable turning passage 1. Cable horizontal turning anchorage system.

[0013] The rotating cable saddle 10, the main cable saddle, and the shunt cable saddle 9 are all provided in a lying state in the cable turning passage 1, and the rotating cable saddle 10, the main cable saddle, and the shunt cable saddle 9 all include a cable saddle body 14 and a grille 15. A notch 16 is horizontally opened at one end of the cable saddle body 14 in the horizontal direction. The rotating cable saddle 10 and the shunt cable saddle 9 are fixedly provided on the anchorage structure 2 inside the cable turning passage 1. Specifically, the grille 15 of the rotating cable saddle 10 is pre-embedded on both side surfaces of the anchorage structure 2 inside the cable turning passage 1, and the grille 15 of the shunt cable saddle 9 is pre-embedded on the side surface of the top portion of the anchorage structure 2 inside the cable turning passage 1 and is symmetrically distributed with respect to the main cable saddle. The rotating cable saddle 10 and the shunt cable saddle 9 are respectively fixedly provided on the anchorage structure 2 inside the cable turning passage 1 through the pre-embedded grille 15. However, along the longitudinal direction of the bridge, the shunt cable saddle 9 is located between the first main cable saddle 6 and the second main cable saddle 7. The force transmission mechanism 8 is fixedly provided on the top surface of the anchorage structure 2 below the top portion of the cable turning passage 1. 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 portion of the cable turning passage 1 and are abutted against the force transmission mechanism 8 through their respective grilles 15. The notches 16 of the rotating cable saddle 10, the shunt cable saddle 9, and the first main cable saddle 6 face outward of the cable turning passage 1, and the notch 16 of the second main cable saddle 7 faces inward of the cable turning passage 1. However, the notches 16 of the first main cable saddle 6 and the second main cable saddle 7 are provided facing away from each other along the central axis direction of the top portion of the cable turning passage 1.Specifically, the cable turning passage 1 has an inverted U-shaped structure. After the cable horizontally passes through the notch 16 of the rotating cable saddle 10 on one side of the cable turning passage 1, it is split into the first cable 4 and the second cable 5 at a certain ratio. The first cable 4 passes through the notch 16 of the first main cable saddle 6 in an inverted U shape in the horizontal direction, and then completes the turning at the top of the cable turning passage 1. The second cable 5 passes through the notch 16 of the shunt cable saddle 9 on the same side, the notch 16 of the second main cable saddle 7, and the notch 16 of the shunt cable saddle 9 on the other side of the second main cable saddle 7 in an M shape in the horizontal direction, and then completes the turning at the top of the cable turning passage 1. After the turning of the first cable 4 and the second cable 5 is completed, they merge, and then the whole passes through the rotating cable saddle 10 on the other side of the cable turning passage 1.

[0014] The force transmission mechanism 8 has a quadrilateral frame structure and includes a transmission lever provided horizontally and intersectingly, a pressure receiving plate wrapped outside the transmission lever, and a grill 15. The grill 15 is pre-embedded in the top surface of the anchorage structure 2 below the top of the cable turning passage 1. The force transmission mechanism 8 is fixedly provided between the first main cable saddle 6 and the second main cable saddle 7 by bolt connection between the pressure receiving plate and the grill 15. The first main cable saddle 6 and the second main cable saddle 7 are respectively in contact with the pressure receiving plates of the force transmission mechanism 8 at corresponding positions through their respective grills 15.

[0015] The cable is branched into a first cable 4 and a second cable 5, and the first cable 4 exhibits an inverted U-shaped turn along the central axis of the top part of the cable turning passage 1, and the second cable 5 exhibits an M-shaped turn at the top part of the cable turning passage 1. Specifically, the second cable 5 interacts with the first cable 4 along the central axis of the cable turning passage 1 and exhibits a U-shaped turn, thereby enabling the reduction of the longitudinal bridge force exerted by the first cable 4 on the anchorage structure 2 via the force transmission mechanism 8. In the traditional cable saddle system, the stress concentration at the position of the central axis of the top part of the cable turning passage 1 for the anchorage structure 2 is avoided. As can be seen from the stress analysis, the longitudinal bridge force of the first cable 4 reduced at the position of the central axis of the top part of the cable turning passage 1 is correspondingly dispersed to the split cable saddle 9, that is, the longitudinal bridge force of the second cable 5 on the inner anchorage structure 2 increases at the positions on both sides of the top part of the cable turning passage 1. In summary, with the above settings, the stress at the position of the central axis of the top part of the anchorage structure 2 can be dispersed 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 reduction intensity of the longitudinal bridge force of the second cable 5 with respect to the first cable 4 and the magnitude of the stress dispersed to the split cable saddle 9 can be adjusted. Specifically, uniform stress bearing in the longitudinal bridge direction of the anchorage structure 2 can be achieved, the longitudinal bridge force at the position of the central axis of the top part of the anchorage structure 2 is the same as the longitudinal bridge force at the positions on both sides of the top part of the anchorage structure 2, and the design difficulty of the anchorage structure 2 can be extremely reduced. On the other hand, the linear shape of the inverted U-shaped turn of the first cable 4 and the linear shape of the M-shaped turn of the second cable 5 are compatible with the structure of the notch 16 of the traditional main cable saddle and split cable saddle 9. In particular, there is no need to customize the cable saddle body 14, and stress concentration on the main cable saddle and split cable saddle 9 caused by the cable can be avoided.

[0016] The main cable saddle and the routing cable saddle 10 have a grill 15 further pre-embedded in the top surface of the anchorage structure 2 below the cable turning passage 1. The cable saddle body 14 of the routing 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 on both side surfaces of the anchorage structure 2 inside the cable turning passage 1 are slidably connected via a friction pair 28 so as to be position-limited along the cable turning direction. The friction pair 28 is a polytetrafluoroethylene plate.

[0017] The anchorage system further includes a cable fixing device 3 fixedly provided in the cable turning passage 1.

[0018] The cable fixing devices 3 are symmetrically distributed in two in the cable turning passage 1. Specifically, along the cable turning direction, the first cable fixing device 3 is fixedly provided upstream of the routing cable saddle 10 on the same side, and the other cable fixing devices 3 are fixedly provided downstream of the routing 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 are made to match the design, realizing linear control of the cable entering and exiting the saddle process, enhancing the linear smoothness of the cable turning, avoiding the appearance of linear bends other than the design, affecting the stress distribution, and further causing stress concentration.

[0020] The cable fixing device 3 includes a fixing frame 20 and a clamping part. The clamping part is slidably connected to the fixing frame 20. The fixing frame 20 is fixedly provided in the cable turning passage 1. The clamping part includes the first jig 23, the second jig 24, and the third jig 25 which are provided crosswise. The first jig 23 is slidably connected to the fixed frame 20 along the vertical direction. The second jig 24 and the third jig 25 are symmetrically distributed on both sides of the first jig 23 and are slidably connected to the fixed frame 20 along the direction inclined to the first jig 23. An interlocking mechanism is provided between the first jig 23, the second jig 24, and the third jig 25 to slide the first jig 23, the second jig 24, and the third jig 25 simultaneously in the direction close to the cable.

[0021] The first jig 23, the first jig 23, and the third jig 25 all have a rod-like structure. One end of the rod-like structure is slidably connected to the fixed frame 20 through the position limiting groove 27, and a chuck 26 is provided at the other end. The chucks 26 of the first jig 23, the second jig 24, and the third jig 25 clamp the cable in three directions in the circumference. The first jig 23 is vertically provided at the center line position of the bottom of the cable. The second jig 24 and the third jig 25 are symmetrically provided on both sides of the first jig 23. The second jig 24 and the third jig 25 both extend in the direction inclined to the first jig 23 and turn to the cable after exceeding a certain distance from the first jig 23. The interlocking mechanism is a fitting structure of a gear 21 and a rack 22. The gears 21 are symmetrically provided on both sides close to one end of the fixed frame 20 of the first jig 23. The first jig 23, the second jig 24, and the third jig 25 are all provided with a one-stage rack 22 at positions corresponding to the gears 21. When the first jig 23 is driven by a power device to approach the bottom of the cable in the vertical direction, the rack 22 of the first jig 23 rotates the gears 21 on both sides. Under the interlocking fit of the gears 21 and the racks 22 of the second jig 24 and the third jig 25, the second jig 24 and the third jig 25 move downward, and further move their respective chucks 26 close to the cable, finally forming a three-direction clamping of the cable circumference.

[0022] By providing an interlocking mechanism, when the first jig 23 moves, the cooperative movement of the second jig 24 and the third jig 25 can be driven, high-speed clamping of the cable can be realized, the structure is simple, the operation is convenient, and at the same time, the clamping structure in three directions is stable, which extremely improves the fixing speed and fixing effect of the cable.

[0023] Between the first main cable saddle 6, the second main cable saddle 7 and the force transmission mechanism 8, a first adjustment mechanism 11 for adjusting the distance between the first main cable saddle 6, the second main cable saddle 7 and the force transmission mechanism 8 is provided.

[0024] The first adjustment mechanism 11 is respectively provided between the grill 15 of the first main cable saddle 6 and the pressure receiving plate corresponding to the force transmission mechanism 8, and between the grill 15 of the second main cable saddle 7 and the pressure receiving plate corresponding to the force transmission mechanism 8 along the longitudinal direction of the bridge.

[0025] The acting force of the second cable 5 on the anchorage structure 2 through the force transmission mechanism 8 in the central axis direction of the top part of the cable turning passage 1, which is opposite to the first cable 4, is related to the splitting ratio of the second cable 5, and is also related to the horizontal relative position between the splitting cable saddle 9 and the second main cable saddle 7. By adjusting the distance between the first main cable saddle 6, the second main cable saddle 7 and the force transmission mechanism 8 through the first adjustment mechanism 11, on the one hand, the adjustment of the reduction state of the longitudinal force of the first cable 4 by the second cable 5 is realized, and after the cable turning is completed, the secondary fine adjustment of the force distribution of the anchorage structure 2 can be realized according to the actual construction situation. On the other hand, the linearity of the turning of the first cable 4 and the second cable 5 can be further adjusted to be as compatible as possible with the notch 16 structure of the cable saddle body 14, so that the cable is always tangent to the notch 16 when entering and leaving the saddle, ensuring the smooth turning of the whole cable and avoiding the occurrence of stress concentration on the cable saddle body 14.

[0026] In the anchorage structure 2 below the main cable saddle, a grille 15 is further embedded in advance. The cable saddle body 14 of the main cable saddle is slidably connected to the grille 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] In the main cable saddle, a grille 15 is further embedded in advance on the top surface of the anchorage structure 2 below the cable turning passage 1. The cable saddle body 14 of the main cable saddle and the grille 15 embedded in advance on the top surface of the anchorage structure 2 below the cable turning passage 1 are slidably connected in the central axis direction of the top part of the cable turning passage 1 via a friction pair 28. The friction pair 28 is a polytetrafluoroethylene plate, which reduces the frictional force between the anchorage structure 2 below the cable turning passage 1 when the first main cable saddle 6 and the second main cable saddle 7 move, facilitates the pitch adjustment operation of the first adjustment mechanism 11, and a position limiting block 29 is provided to prevent the main cable saddle from deviating from the central axis direction 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 the mounting plate 17 is fixedly provided on the first main cable saddle 6 and the second main cable saddle 7, and the other side is rotatably connected to the damper hinge 19 in the axial direction.

[0029] The damper hinge 19 includes a rotating shaft and hinge plates rotatably provided on both sides of the rotating shaft. Along the longitudinal direction of the bridge, one side of the mounting plate 17 is provided on the grill 15 of the first main cable saddle 6 and the second main cable saddle 7 by bolt fixation, and the rotating shaft of the damper hinge 19 is fixedly provided on the other side of the mounting plate 17. The hinge plate of the damper hinge 19 abuts against the force transmission mechanism 8. By being rotatably provided in the axial direction between the damper hinge 19 and the mounting plate 17, the distance between the first main cable saddle 6, the second main cable saddle 7 and the force transmission mechanism 8 can be adjusted by the force-bearing rotation of the damper hinge 19. On the other hand, when the damper hinge 19 rotates, it generates a reaction force against the longitudinal force of the bridge of the first main cable saddle 6 and the second main cable saddle 7, and the magnitude of the reaction force and the turning angle exhibit a positive correlation, reducing the pressure received by the force transmission mechanism 8, and further reducing the longitudinal force applied to the main cable saddle at the central axis position of the cable turning passage 1 to the anchorage structure 2 through the force transmission mechanism 8, reducing the overall force received by the anchorage structure 2. The provision of the damper hinge 19 can realize the self-adaptation to the interaction between the first cable 4 and the second cable 5 and perform self-adaptive adjustment of the cable linearity.

[0030] The first adjustment mechanism 11 includes a toothed plate 18. The toothed plate 18 is fixedly provided on the force transmission mechanism 8 to limit the axial rotation of the damper hinge 19. The hinge plate of the damper hinge 19 is axially telescopic.

[0031] To ensure the controllability of the distance between the first main cable saddle 6, the second main cable saddle 7 and the force transmission mechanism 8, a toothed plate 18 is further provided on the pressure receiving plate at the corresponding position of the force transmission mechanism 8 to limit and engage with the hinge plate of the damper hinge 19. In actual use, first, the hinge plate is axially contracted, the hinge plate is adjusted to rotate to an appropriate angle, and then the hinge plate is axially extended to abut against the toothed plate 18 for position limitation.

[0032] The shunt cable saddle 9 includes a second adjustment mechanism 12 for adjusting the angle between the cable saddle body 14 of the shunt cable saddle 9 and the anchorage structure 2 inside the cable turning passage 1. The shunt cable saddle 9 is fixedly provided at the top of the cable turning passage 1 by the second adjustment mechanism 12.

[0033] The shunt cable saddle 9 includes a cable saddle body 14, a second adjustment mechanism 12, and a grill 15. The second adjustment mechanism 12 is located at the central position between the cable saddle body 14 and the side surface of the top of the anchorage structure 2 inside the cable turning passage 1 where the grill 15 is pre-embedded. The second adjustment mechanism 12 is fixedly provided with the cable saddle body 14 and the grill 15. When the second cable 5 turns, the angle between the cable saddle body 14 and the anchorage structure 2 inside the cable turning passage 1 is adjusted through the second adjustment mechanism 12, so that it can be adapted to the notch 16 structure of the cable saddle body 14 of the shunt cable saddle 9 as much as possible. The second cable 5 is always tangent to the notch 16 of the shunt cable saddle 9 when entering and exiting the saddle, ensuring that the entire turn of the second cable 5 is smooth and avoiding stress concentration on the cable saddle body 14.

[0034] The shunt cable saddle 9 includes a buffer mechanism 13 provided between the cable saddle body 14 of the shunt cable saddle 9 and the anchorage structure 2 inside the cable turning passage 1.

[0035] The shunt cable saddle 9 includes a cable saddle body 14, a buffer mechanism 13, and a grill 15. The buffer mechanism 13 is a high-strength spring. The high-strength springs are evenly distributed at the four corners between the cable saddle body 14 and the side surface of the top of the anchorage structure 2 inside the cable turning passage 1 where the grill 15 is pre-embedded. When the cable turns, due to the elastic deformation of the high-strength spring, the longitudinal and transverse forces applied by the second cable 5 to the anchorage structure 2 at both sides of the top of the cable turning passage 1 are reduced, and further the force received by the entire anchorage structure 2 is reduced.

[0036] The second adjustment mechanism 12 includes a base, a link, and a connection plate. The base and the connection plate are respectively provided by being fixed to the anchorage structure 2 inside the cable turning passage 1 and the cable saddle body 14. One end of the link is swingably connected to the base, and the other end is fixedly provided to the connection plate.

[0037] The base and the connection plate are respectively embedded in advance on the side surface of the top portion of the anchorage structure 2 inside the cable turning passage 1 and the grille 15, and are fixedly connected to the cable saddle body 14 of the cable saddle by bolts. One end of the link is swingably connected to the base in the horizontal direction, and the other end is welded and fixed to the connection plate.

[0038] In another embodiment, in order to enhance the smoothness of the swing of the second adjustment mechanism 12, a grille 15 is further embedded in advance on the top surface of the anchorage structure 2 below the cable turning passage 1 of the shunt cable saddle 9. The cable saddle body 14 of the shunt cable saddle 9 and the grille 15 embedded in advance on the top surface of the anchorage structure 2 below the cable turning passage 1 are slidably connected via a friction pair 28. The friction pair 28 is a polytetrafluoroethylene plate.

[0039] The step S1 of constructing the anchorage structure 2, embedding the grilles 15 of the rotating cable saddle 10, the main cable saddle, and the shunt cable saddle 9 in advance, and reserving the cable turning passage 1, The step S2 of installing the rotating cable saddle 10, the main cable saddle, the shunt cable saddle 9, and the cable fixing device 3, The step S3 of turning the cable, The step S31 of pulling the cable so as to pass through the notch 16 of the cable fixing device 3 on one side of the cable turning passage 1 and the rotating cable saddle 10, and then dispersing the cable at a certain ratio to form the first cable 4 and the second cable 5, The step S32 of pulling the first cable 4 so as to pass through the notch 16 of the first main cable saddle 6 and then completing the turning, Pull the second cable 5 so that it sequentially passes through the notch 16 of the shunt cable saddle 9 on the same side, the notch 16 of the second main cable saddle 7, and the notch 16 of the shunt cable saddle 9 on the other side of the second main cable saddle 7, and then complete the turning step S33. After the turning of the first cable 4 and the second cable 5 is completed, they merge, and then pass through the notch 16 of the routing cable saddle 10 provided on the other side of the cable turning passage 1 as a whole and the cable fixing device 3 in step S34.
