Description

Cable horizontal rotary anchor system and construction method Technical Field

[0001] The present application relates to the technical field of suspension bridges, and in particular to a cable horizontal rotation anchoring system and a construction method. Background Art

[0002] In order to realize the 180° rotation of the main cable of the revolving cable suspension bridge, an appropriate saddle system must be equipped to meet the requirements of internal force transmission between the main cable and the anchor and spatial displacement of the main cable. The traditional saddle system is composed of two rotating saddles symmetrically arranged on both sides of the cable revolving channel and a main saddle arranged on the top of the cable revolving channel. The rotating saddles are specifically fixed on the side surfaces on both sides of the anchor structure inside the cable revolving channel, and the main saddle is specifically fixed on the side surface of the top of the anchor structure inside the cable revolving channel. Both the rotating saddle and the main saddle are in a horizontal state, and the horizontal rotation and support of the main cable are achieved through the grooves laterally arranged on the saddle body. However, the traditional main cable horizontal revolving saddle system will cause stress concentration on the saddle body and the anchor structure while solving the main cable rotation problem. It is not suitable for mountains with harsh geological conditions. It is very easy for the anchor system to become unstable, and then a safety accident will occur.

[0003] Therefore, it is necessary to provide an improved technical solution to the above-mentioned deficiencies in the prior art.

On the other hand, the inverted U-shaped turning line of the first cable and the M-shaped turning line of the second cable fit the notch structure of the traditional main saddle and diverter saddle, and there is no need to specially customize the saddle body to avoid stress concentration of the cable on the main saddle and diverter cable.

[0029] The cable horizontal rotation anchor system is arranged at the end of the suspension bridge along the longitudinal bridge direction. For the sake of clarity, it is now defined that the farthest end of the cable rotation channel 1 from the suspension bridge along the longitudinal bridge direction is the top of the cable rotation channel 1, and the farthest end of the anchor structure 2 from the suspension bridge along the longitudinal bridge direction is the top of the anchor structure 2.

[0030] The following will further describe in detail a cable horizontal rotary anchoring system and construction method of the present application with reference to Figures 1-7.

[0031] A cable horizontal rotary anchoring system, the anchoring system includes an anchoring structure 2, a rotary cable saddle 10, a main cable saddle, and a diversion cable saddle 9;

[0032] A cable turning channel 1 is provided in the anchoring structure 2; turning cable saddles 10 are symmetrically distributed on both sides of the cable turning channel 1; a main cable saddle is provided at the central axis of the top of the cable turning channel 1; and a diversion cable saddle 9 is fixedly provided at the top of the cable turning channel 1 and symmetrically distributed along the main cable saddle.

[0033] The main cable saddle includes a first main cable saddle 6 and a second main cable saddle 7. The notch 16 of the first main cable saddle 6 and the notch 16 of the second main cable saddle 7 are arranged opposite to each other along the central axis of the top of the cable rotation channel 1. The first main cable saddle 6 and the second main cable saddle 7 are axially connected by a force transmission mechanism 8.

[0034] The force transmission mechanism 8 is fixedly arranged in the cable rotation channel 1; the diversion saddle 9 includes a saddle body 14;

[0035] The cable includes a first cable 4 and a second cable 5. The first main saddle 6 is used for the inverted U-shaped rotation of the first cable 4 at the top of the cable rotation channel 1. The second main saddle 7 and the diversion saddle 9 are used for the M-shaped rotation of the second cable 5 at the top of the cable rotation channel 1.

[0036] The rotating saddle 10, main saddle, and diverter saddle 9 are all horizontally arranged in the cable turn channel 1 and include a saddle body 14 and a grille 15. A notch 16 is transversely defined at one horizontal end of the saddle body 14. The rotating saddle 10 and diverter saddle 9 are fixedly mounted on the anchor structure 2 inside the cable turn channel 1. Specifically, the grille 15 of the rotating saddle 10 is embedded in the sides of the anchor structure 2 inside the cable turn channel 1, while the grille 15 of the diverter saddle 9 is embedded in the sides of the top of the anchor structure 2 inside the cable turn channel 1 and is symmetrically distributed along the main saddle. The rotating saddle 10 and diverter saddle 9 are each fixedly connected to the anchor structure 2 inside the cable turn channel 1 via their respective embedded grilles 15. In the longitudinal direction of the bridge, the diverter saddle 9 is located between the first main saddle 6 and the second main saddle 7. The force transmission mechanism 8 is fixedly mounted on the top surface of the anchor structure 2 on the lower side of the top of the cable turn channel 1. The first and second main cable saddles 6 and 7 are mounted on the top surface of the anchor structure 2 on the lower side of the top of the cable turn channel 1 and abut the force transmission mechanism 8 via their respective grilles 15. The notches 16 of the turning saddle 10, diverter saddle 9, and first main cable saddle 6 face the outside of the cable turn channel 1, while the notch 16 of the second main cable saddle 7 faces the inside of the cable turn channel 1. The notches 16 of the first and second main cable saddles 6 and 7 are arranged in opposite directions along the central axis of the top of the cable turn channel 1. The cable turning channel 1 is specifically an inverted U-shaped structure. After the cable passes horizontally through the slot 16 of the turning saddle 10 on one side of the cable turning channel 1, it is diverted into the first cable 4 and the second cable 5 according to a certain proportion. The first cable 4 passes through the slot 16 of the first main saddle 6 in an inverted U shape in the horizontal direction and completes the rotation at the top of the cable turning channel 1. The second cable 5 passes through the slot 16 of the diversion saddle 9 on the same side, the slot 16 of the second main saddle 7, and the slot 16 of the diversion saddle 9 on the other side of the second main saddle 7 in an M shape in the horizontal direction and completes the rotation at the top of the cable turning channel 1. The first cable 4 and the second cable 5 merge after the rotation is completed, and then pass through the turning saddle 10 on the other side of the cable turning channel 1 as a whole.

[0037] The force transmission mechanism 8 is a square frame structure consisting of horizontally intersecting force transmission rods, pressure plates wrapped around the outside of the force transmission rods, and a grille 15. The grille 15 is embedded in the top surface of the anchor structure 2 on the lower side of the top of the cable turnway 1. 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 plates to the grille 15. The first main cable saddle 6 and the second main cable saddle 7 are each in contact with the corresponding pressure plates of the force transmission mechanism 8 through their respective grilles 15.

[0038] By dividing the cable into a first cable 4 and a second cable 5, and setting the first cable 4 to make an inverted U-shaped rotation at the central axis of the top of the cable turning channel 1, and the second cable 5 to make an M-shaped rotation at the top of the cable turning channel 1, specifically, the second cable 5 interacts with the first cable 4 at the central axis of the cable turning channel 1 and makes a U-shaped rotation, it is possible to reduce the longitudinal bridge force applied by the first cable 4 to the anchoring structure 2 through the force transmission mechanism 8, so as to avoid stress concentration of the anchoring structure 2 at the central axis position of the top of the cable turning channel 1 in the traditional saddle system. At the same time, through force analysis, it can be seen that the longitudinal bridge force of the first cable 4 reduced at the central axis position of the top of the cable turning channel 1 is correspondingly dispersed to the diversion saddle 9, that is, it is increased to the longitudinal bridge force of the second cable 5 on the inner anchoring structure 2 at the two sides of the top of the cable turning channel 1. In summary, through the above settings, the stress at the top center axis position of the anchoring structure 2 can be dispersed to both sides of the top of the anchoring structure 2 to avoid stress concentration of the anchoring structure 2 at the top center axis of the cable turning channel 1. Furthermore, by adjusting the distribution ratio of the first cable 4 and the second cable 5, the reduction effect of the second cable 5 on the longitudinal bridge force of the first cable 4 and the stress dispersed to the diversion saddle 9 can be adjusted. Specifically, uniform longitudinal bridge force of the anchoring structure 2 can be achieved, that is, the longitudinal bridge force at the top center axis position of the anchoring structure 2 is made the same as the longitudinal bridge force at both sides of the top of the anchoring structure 2, which greatly reduces the design difficulty of the anchoring structure 2; on the other hand, the inverted U-shaped turning line of the first cable 4 and the M-shaped turning line of the second cable 5 fit the notch 16 structure of the traditional main saddle and diversion saddle 9, and there is no need to specially customize the saddle body 14 to avoid stress concentration of the cable on the main saddle and diversion saddle 9.

[0039] The main saddle and the rotating saddle 10 are also pre-embedded with a grille 15 on the top surface of the anchoring structure 2 on the lower side of the cable turning channel 1. The saddle body 14 of the rotating saddle 10 and the grille 15 embedded in the top surface of the anchoring structure 2 on the lower side of the cable turning channel 1 and the grille 15 embedded in the side surfaces of the anchoring structure 2 on the inner side of the cable turning channel 1 are connected by a friction pair 28 for limited sliding along the cable turning direction. The friction pair 28 is a polytetrafluoroethylene plate.

[0040] The anchoring system further comprises a cable fixing device 3 , which is fixedly arranged in the cable turning channel 1 .

[0041] Two cable fixing devices 3 are symmetrically distributed in the cable rotation channel 1. Specifically, along the cable rotation direction, the first cable fixing device 3 is fixed on the upstream side of the turning saddle 10 on the same side, and the other cable fixing device 3 is fixed on the downstream side of the turning saddle 10 on the same side.

[0042] 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 kept consistent with the design, the linear control of the cable entering and exiting the saddle can be achieved, the smoothness of the cable rotation line can be improved, and linear bending beyond the design can be avoided, which affects the stress distribution and even causes stress concentration.

[0043] The cable fixing device 3 includes a fixing frame 20 and a clamping portion. The clamping portion is slidably connected to the fixing frame 20. The fixing frame 20 is fixedly arranged in the cable rotation channel 1.

[0044] The clamping portion includes a first clamp 23, a second clamp 24, and a third clamp 25 arranged crosswise. The first clamp 23 is slidably connected to the fixing frame 20 in the vertical direction. The second clamp 24 and the third clamp 25 are symmetrically distributed on both sides of the first clamp 23 and are slidably connected to the fixing frame 20 in a direction inclined toward the first clamp 23.

[0045] A linkage mechanism is provided between the first clamp 23 and the second clamp 24 and the third clamp 25, for simultaneously driving the first clamp 23, the second clamp 24 and the third clamp 25 to slide in a direction close to the cable.

[0046] The first clamp 23, the second clamp 24, and the third clamp 25 are all rod-shaped structures. One end of the rod-shaped structure is slidably connected to the fixed frame 20 via a limit slot 27, and the other end is provided with a clamp 26. The clamps 26 of the first clamp 23, the second clamp 24, and the third clamp 25 provide a three-dimensional clamping of the cable circumference. The first clamp 23 is vertically positioned at the centerline of the bottom of the cable. The second clamp 24 and the third clamp 25 are symmetrically positioned on either side of the first clamp 23. The second clamp 24 and the third clamp 25 both extend in a direction inclined toward the first clamp 23 and extend a certain distance beyond the first clamp 23 before rotating back toward the cable. The linkage mechanism is a matching structure of a gear 21 and a rack 22. The gear 21 is symmetrically arranged on both sides of the first clamp 23 near one end of the fixed frame 20. A rack 22 is set at the position corresponding to the gear 21 of the first clamp 23, the second clamp 24, and the third clamp 25. When the first clamp 23 is driven by the power device to move upward in the vertical direction close to the bottom of the cable, the rack 22 of the first clamp 23 drives the gears 21 on both sides to rotate. Under the linkage cooperation of the gear 21 and the rack 22 of the second clamp 24 and the third clamp 25, the second clamp 24 and the third clamp 25 move downward, thereby driving their respective clamps 26 to approach the cable, and finally forming a three-way clamping on the circumference of the cable.

[0047] By setting up a linkage mechanism, the coordinated movement of the second clamp 24 and the third clamp 25 is driven when the first clamp 23 moves, so that the cable can be clamped quickly. The structure is simple and the operation is convenient. At the same time, the three-way clamping structure is stable, which greatly improves the fixing speed and fixing effect of the cable.

[0048] 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 .

[0049] Along the longitudinal bridge direction, the first adjustment mechanism 11 is respectively arranged between the grid 15 of the first main cable saddle 6 and the pressure plate corresponding to the force transmission mechanism 8, and between the grid 15 of the second main cable saddle 7 and the pressure plate corresponding to the force transmission mechanism 8.

[0050] Since the second cable 5 applies a force opposite to that of the first cable 4 to the anchoring structure 2 in the direction of the central axis of the top of the cable turning channel 1 through the force transmission mechanism 8, in addition to being related to the diversion ratio of the second cable 5, it is also related to the relative position of the diversion saddle 9 and the second main saddle 7 in the horizontal direction. By adjusting the distance between the first main saddle 6, the second main saddle 7 and the force transmission mechanism 8 through the first adjustment mechanism 11, on the one hand, the second cable 5 can adjust the longitudinal bridge force reduction state of the first cable 4, so that after the cable rotation is completed, the force distribution of the anchoring structure 2 can still be fine-tuned according to the actual construction conditions; on the other hand, the turning line of the first cable 4 and the second cable 5 can be further adjusted to fit the slot 16 structure of the saddle body 14 as much as possible. The cable always remains tangent to the slot 16 when entering and exiting the saddle, ensuring smooth overall rotation of the cable and avoiding stress concentration on the saddle body 14.

[0051] The anchoring structure 2 on the lower side of the main saddle is also pre-buried with a grid 15 , and the saddle body 14 of the main saddle is slidably connected to the grid 15 pre-buried in the anchoring structure 2 on the lower side of the main saddle along the top central axis of the cable turning channel 1 .

[0052] The main saddle is also embedded with a grille 15 on the top surface of the anchoring structure 2 on the lower side of the cable turn channel 1. The saddle body 14 of the main saddle and the grille 15 embedded in the top surface of the anchoring structure 2 on the lower side of the cable turn channel 1 are slidably connected along the central axis of the top of the cable turn channel 1 through a friction pair 28. The friction pair 28 is a polytetrafluoroethylene plate, which reduces the friction between the first main saddle 6 and the second main saddle 7 and the anchoring structure 2 on the lower side of the cable turn channel 1 when moving, facilitates the distance adjustment operation of the first adjustment mechanism 11, and provides a limit block 29 to prevent the main saddle from deviating from the central axis of the top of the cable turn channel 1.

[0053] The first adjustment mechanism 11 includes a mounting plate 17 and a damping hinge 19 . One side of the mounting plate 17 is fixedly connected to the first main cable saddle 6 and the second main cable saddle 7 , and the other side is axially rotatably connected to the damping hinge 19 .

[0054] The damping hinge 19 includes a rotating shaft and hinge plates rotatably mounted on either side of the shaft. Along the longitudinal bridge direction, one side of the mounting plate 17 is bolted to the grille 15 of the first and second main saddles 6 and 7. The other side of the mounting plate 17 is fixed to the rotating shaft of the damping hinge 19, and the hinge plates of the damping hinge 19 abut against the force transmission mechanism 8. By setting the damping hinge 19 and the mounting plate 17 in axial rotation connection, on the one hand, the distance between the first main saddle 6, the second main saddle 7 and the force transmission mechanism 8 can be adjusted through the force rotation of the damping hinge 19; on the other hand, the damping hinge 19 will generate a reaction force to the longitudinal bridge force of the first main saddle 6 and the second main saddle 7 when rotating, and the magnitude of the reaction force is positively correlated with the rotation angle, so as to reduce the pressure on the force transmission mechanism 8, and thereby reduce the longitudinal bridge force applied by the main saddle to the anchor structure 2 at the central axis position of the cable turning channel 1 through the force transmission mechanism 8, thereby reducing the overall force of the anchor structure 2. The setting of the damping hinge 19 can also achieve adaptation to the interaction between the first cable 4 and the second cable 5, so as to perform adaptive adjustment of the cable line shape.

[0055] The first adjustment mechanism 11 includes a tooth plate 18, which is fixedly connected to the force transmission mechanism 8 and is used to limit and damp the axial rotation of the hinge 19;

[0056] The hinge plate of the damping hinge 19 can be axially retractable.

[0057] 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 is controllable, a tooth plate 18 is also provided on the pressure plate at the corresponding position of the force transmission mechanism 8 to cooperate with the hinge plate limit of the damping hinge 19. In actual use, the hinge plate is first axially contracted, the hinge plate is adjusted to rotate to a suitable angle, and then the hinge plate is axially extended again and abutted against the tooth plate 18 for limit.

[0058] The diverter saddle 9 includes a second adjustment mechanism 12 for adjusting the angle between the saddle body of the diverter saddle 9 and the anchoring structure 2 inside the cable turn channel 1 ; the diverter saddle 9 is fixedly arranged on the top of the cable turn channel 1 through the second adjustment mechanism 12 .

[0059] The diverter saddle 9 includes a saddle body 14, a second adjustment mechanism 12, and a grille 15. The second adjustment mechanism 12 is located at the center between the saddle body 14 and the grille 15 embedded in the top side of the anchor structure 2 inside the cable rotation channel 1. The second adjustment mechanism 12 is fixedly connected to the saddle body 14 and the grille 15. When the second cable 5 is rotated, the second adjustment mechanism 12 adjusts the angle between the saddle body 14 and the anchor structure 2 inside the cable rotation channel 1 to fit the notch 16 structure of the saddle body 14 of the diverter saddle 9 as closely as possible. This ensures that the second cable 5 is always tangent to the notch 16 of the diverter saddle 9 when entering and exiting the saddle, ensuring smooth overall rotation of the second cable 5 and avoiding stress concentration on the saddle body 14.

[0060] The diverter saddle 9 includes a buffer mechanism 13 , which is disposed between a saddle body 14 of the diverter saddle 9 and the anchoring structure 2 inside the cable turning channel 1 .

[0061] The diverter saddle 9 comprises a saddle body 14, a buffer mechanism 13, and a grille 15. The buffer mechanism 13 is a high-strength spring evenly distributed at the four corners between the saddle body 14 and the grille 15 embedded in the top side of the anchor structure 2 inside the cable turnway 1. During cable rotation, the elastic deformation of the high-strength springs reduces the longitudinal bridge force exerted by the second cable 5 on the anchor structure 2 at both sides of the top of the cable turnway 1, further reducing the overall stress on the anchor structure 2.

[0062] The second adjustment mechanism 12 includes a base, a connecting rod, and a connecting plate. The base and the connecting plate are fixedly connected to the anchor structure 2 and the saddle body 14 inside the cable rotation channel 1 respectively; one end of the connecting rod is swingably connected to the base, and the other end is fixedly connected to the connecting plate.

[0063] The base and the connecting plate are respectively fixedly connected to the grille 15 and the saddle body 14 embedded in the top side of the anchor structure 2 inside the cable turning channel 1 by bolts. One end of the connecting rod is connected to the base in a horizontal swing direction, and the other end is welded to the connecting plate.

[0064] In other embodiments, in order to increase the smoothness of the swinging of the second adjustment mechanism 12, a grille 15 is also pre-embedded in the top surface of the anchoring structure 2 on the lower side of the cable turning channel 1 of the diverter saddle 9. The saddle body 14 of the diverter saddle 9 and the grille 15 pre-embedded in the top surface of the anchoring structure 2 on the lower side of the cable turning channel 1 are slidably connected through a friction pair 28, and the friction pair 28 is a polytetrafluoroethylene plate.

[0065] A construction method for a cable horizontal rotary anchoring system, comprising:

[0066] Step S1, constructing the anchoring structure 2, pre-embedding the turning saddle 10, the main saddle, the grid 15 of the diversion saddle 9 and reserving the cable turning channel 1;

[0067] Step S2, installing the transfer saddle 10, the main saddle, the diversion saddle 9, and the cable fixing device 3;

[0068] Step S3, cable rotation;

[0069] Step S31: After the traction cable passes through the cable fixing device 3 on one side of the cable turning channel 1 and the notch 16 of the turning saddle 10 in sequence, the cable is dispersed in a certain proportion to form a first cable 4 and a second cable 5;

[0070] Step S32, pulling the first cable 4 through the notch 16 of the first main saddle 6 and completing the rotation;

[0071] Step S33, the second cable 5 is pulled through the notch 16 of the diversion saddle 9 on the same side, the notch 16 of the second main saddle 7, and the notch 16 of the diversion saddle 9 on the other side of the second main saddle 7 to complete the rotation;

[0072] In step S34 , the first cable 4 and the second cable 5 are combined after the rotation is completed, and the entire cable passes through the notch 16 of the cable saddle 10 and the cable fixing device 3 arranged on the other side of the cable rotation channel 1 in sequence.
