Description
Technical Field
[0001] This utility model relates to the field of bridge construction anchoring technology, and in particular to a steel strand oblique anchoring structure using the inclined tie-hanging method. Background Technology
[0002] In bridge cantilever construction, the cable-stayed anchorage method is widely used for temporary anchorage and attitude control of arch bridges and cable-stayed bridges. Among them, the steel strand is the main load-bearing component, and the stability of its anchorage structure directly affects the construction safety and accuracy.
[0003] Currently, traditional anchoring structures lack angle adjustment capabilities and cannot adapt to the construction needs of steel strands with different oblique angles, thus requiring the development of anchoring components with different angles. Utility Model Content
[0004] The purpose of this utility model is to provide a slanted anchoring structure for steel strands using a slanted fastening method. This solves the technical problem that traditional anchoring structures in the prior art lack angle adjustment functions and cannot adapt to the construction needs of steel strands with different slant angles, thus requiring the development of anchoring components with different angles.
[0005] To achieve the above objectives, this utility model employs a slanted anchoring structure for steel strands using a diagonal fastening method. The structure includes a steel strand body, with semi-circular mounting shells at both ends. Each semi-circular mounting shell contains a first arc-shaped frame. A fixed plate is located at one end of the first arc-shaped frame, and a rotating shaft is located on one side of the first arc-shaped frame. The rotating shaft passes through the fixed plate and connects to a longitudinal moving component. The longitudinal moving component drives the rotating shaft to rotate longitudinally, and one end of the longitudinal moving component is located at one end of the fixed plate. A second arc-shaped frame is located on one side of the fixed plate, with a connecting rod at one end of the second arc-shaped frame connecting to a transverse moving component. The transverse moving component drives the connecting rod to rotate transversely, and the transverse moving component is located on the fixed plate. A semi-circular fixed shell is located on the second arc-shaped frame, and a fixed seat is located on one side of the semi-circular fixed shell.
[0006] The fixing base has through holes at its four corners.
[0007] The fixed plate has two semi-circular grooves that mate with the first arc-shaped frame; the fixed plate has a through groove, and the rotating shaft passes through the through groove.
[0008] The longitudinal movement component includes a first servo motor, which is fixedly connected to a fixed disk; a first gear, which is fixedly connected to the output end of the first servo motor; and a second gear, which is fixedly connected to a rotating shaft and meshes with the first gear.
[0009] The lateral movement component includes a second servo motor, which is fixedly connected to a fixed disk; a third gear, which is fixedly connected to the output end of the second servo motor; and a fourth gear, which is fixedly connected to a connecting rod and meshes with the third gear. Beneficial effects
[0010] The first servo motor drives the first gear and the second gear to mesh and transmit power, which drives the rotating shaft to rotate in the through groove of the fixed plate. This causes the first arc frame to drive the semi-circular mounting shell to rotate longitudinally around the rotating shaft, ultimately realizing the longitudinal angle adjustment of the end of the steel strand body. The longitudinal angle can be flexibly adjusted within the range of 0-180° according to the vertical angle of the steel strand in bridge cantilever construction (such as the angled tension requirements of different heights of the arch rib of the arch bridge). There is no need to replace the special anchoring components, which is suitable for various scenarios from low-angle angled tension to near-vertical anchoring. The second servo motor drives the third and fourth gears to mesh. Since the semi-circular fixed shell is fixed to the construction structure through the fixed seat, the connecting rod cannot rotate. The reaction force drives the fixed plate to rotate laterally around the connecting rod. The fixed plate drives the semi-circular mounting shell and the end of the steel strand body to rotate laterally through the first arc frame. It can achieve 0-180° lateral angle adjustment for different skew angles in the horizontal direction of the bridge (such as the difference in the horizontal angle between the main beam and the tower of the cable-stayed bridge), meet the anchoring requirements of steel strands in different directions in the same construction area, and avoid the component customization cost caused by the fixed angle of the traditional structure. The two ends of the steel strand are tightly connected to the first arc frame through semi-circular mounting shells. The first arc frame, the fixing plate, and the second arc frame form a triangular force-bearing structure. With the through holes at the four corners of the fixing seat (rigidly fixed to the construction structure by bolts), the tension of the steel strand can be evenly transferred to the main structure of the bridge.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] This utility model provides a slanted anchoring structure for steel strands using a slanted hook method, comprising a steel strand body 101, a semi-circular mounting shell 102, a first arc-shaped frame 103, a fixing plate 104, a rotating shaft 105, a second arc-shaped frame 106, a connecting rod 107, a semi-circular fixing shell 108, a fixing seat 109, a first servo motor 113, a first gear 114, a second gear 115, a second servo motor 116, a third gear 117, and a fourth gear 118. The aforementioned solution solves the problem that traditional anchoring structures lack angle adjustment functions and cannot adapt to the construction needs of steel strands with different slant angles, thus requiring the development of anchoring components with different angles.
[0020] In this specific embodiment, the steel strand body 101 has semi-circular mounting shells 102 at both ends. Each semi-circular mounting shell 102 contains a first arc-shaped frame 103. A fixed plate 104 is located at one end of the first arc-shaped frame 103, and a rotating shaft 105 is located on one side of the first arc-shaped frame 103. The rotating shaft 105 passes through the fixed plate 104 and is connected to a longitudinal moving component. The longitudinal moving component drives the rotating shaft 105 to rotate longitudinally, and one end of the longitudinal moving component is located at one end of the fixed plate 104. A second arc-shaped frame 106 is located on one side of the fixed plate 104, and a connecting rod 107 is located at one end of the second arc-shaped frame 106 and connected to a transverse moving component. The transverse moving component drives the connecting rod 107 to rotate transversely, and the transverse moving component is located on the fixed plate 104. A semi-circular fixed shell 108 is located on the second arc-shaped frame 106, and a fixed seat 109 is located on one side of the semi-circular fixed shell 108. Each of the fixed seats 109 is installed at a designated position. Then, both ends of the steel strand body 101 are respectively installed on the two semi-circular mounting shells 102. The longitudinal moving component drives the rotating shaft 105 to rotate, the rotating shaft 105 drives the first arc frame 103 to rotate, the first arc frame 103 drives the semi-circular mounting shell 102 to rotate longitudinally, and the semi-circular mounting shell 102 drives one end of the steel strand body 101 to move longitudinally. The transverse moving component drives the connecting rod 107 to rotate. Since the semi-circular fixed shell 108 is fixedly installed by the fixed seat 109, the second arc frame 106 will not rotate. At this time, the transverse moving component drives the fixed plate 104 to rotate, and the fixed plate 104 drives the semi-circular mounting shell 102 to rotate laterally through the first arc frame 103. The semi-circular mounting shell 102 drives one end of the steel strand body 101 to move laterally, thereby adapting to the construction requirements of steel strands with different skew angles.
[0021] The fixing base 109 has through holes 110 at its four corners.
[0022] Secondly, the fixed plate 104 is provided with two semi-circular grooves 111 that cooperate with the first arc frame 103; the fixed plate 104 is provided with a through groove 112, and the rotating shaft 105 passes through the through groove 112.
[0023] Meanwhile, the longitudinal movement component includes a first servo motor 113, which is fixedly connected to the fixed disk 104; a first gear 114, which is fixedly connected to the output end of the first servo motor 113; and a second gear 115, which is fixedly connected to the rotating shaft 105 and meshes with the first gear 114. The first servo motor 113 drives the first gear 114 to rotate, the first gear 114 drives the second gear 115 to rotate, and the second gear 115 drives the rotating shaft 105 to rotate.
[0024] Additionally, the lateral movement assembly includes a second servo motor 116, which is fixedly connected to the fixed disk 104; a third gear 117, which is fixedly connected to the output end of the second servo motor 116; and a fourth gear 118, which is fixedly connected to the connecting rod 107 and meshes with the third gear 117. The second servo motor 116 drives the third gear 117 to rotate, the third gear 117 drives the fourth gear 118 to rotate, and the fourth gear 118 drives the connecting rod 107 to rotate.
[0025] In this embodiment, a steel strand oblique anchoring structure using a diagonal fastening method is employed. Two fixing seats 109 are installed at designated positions, and then secured with bolts passing through the through holes 110 on the fixing seats 109. Subsequently, both ends of the steel strand body 101 are installed on two semi-circular mounting shells 102. When angle adjustment is required, the first servo motor 113 drives the first gear 114 to rotate, which in turn drives the second gear 115. The second gear 115, via the rotating shaft 105, drives the first arc-shaped frame 103 to rotate, which in turn drives the semi-circular mounting shells 102. The shell 102 rotates longitudinally, and the semi-circular mounting shell 102 drives one end of the steel strand body 101 to move longitudinally; the second servo motor 116 drives the third gear 117 to rotate, and the third rack drives the fourth gear 118 to rotate. Since the semi-circular fixed shell 108 is fixedly installed through the fixed seat 109, and the second arc frame 106 is installed on the semi-circular fixed shell 108, the second arc frame 106 will not rotate, so that the fixed plate 104 rotates laterally. The fixed plate 104 drives the semi-circular mounting shell 102 to move laterally through the first arc frame 103, so as to adapt to the construction requirements of steel strands with different skew angles.
[0026] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
