Description

Technical Field

[0001] The utility model relates to the technical field of bridges, in particular to a bridge suspension cable anchoring structure. Background Art

[0002] Compared with ground-anchored suspension bridges, self-anchored suspension bridges anchor the main cables at both ends of the stiffening beams. There is no need to build bulky anchors, thus avoiding the damage to the ecological environment caused by anchor excavation. The anchoring area of ​​the stiffening beam is to evenly transfer the huge concentrated force of the main cable to the entire section of the stiffening beam. Therefore, the structure of the main cable anchoring area is crucial and determines the overall layout of the bridge to a certain extent. Therefore, during the construction process, anchoring structure components are needed to connect the main cable and the stiffening beam.

[0003] Currently, the existing anchoring structure components are generally composed of a base plate and a connecting seat. The base plate is provided with mounting holes for connection with embedded bolts. However, there is generally an error in the length of the cable during installation, and the position of the connecting seat cannot generally be fine-tuned during the installation process, resulting in certain inconveniences in adjusting the tightness of the cable. Therefore, a bridge suspension anchoring structure is proposed to solve the above technical problems. Utility Model Content

[0006] A plurality of connection holes for docking with embedded bolts are provided on the base, the connection screw is vertically installed at the center of the upper surface of the base, and the rotating member is arranged on the outside of the connection screw;

[0007] The rotating member comprises a connecting ring, at least two driving rods and a connecting seat;

[0008] The connecting ring is threadedly connected to the outer side of the connecting screw rod, at least two driving rods are arranged on both sides of the connecting ring at a left-right interval, and the connecting seat is arranged between the opposite sides of the at least two driving rods and is flush with the upper end surfaces of the at least two driving rods;

[0009] The connecting assembly is assembled on the rotating member so as to be detachably connected with the cable.

[0010] Furthermore, the connecting ring and the connecting seat retain the length of a connecting screw.

[0011] Furthermore, a fastener is threadedly connected to the connecting ring.

[0012] Furthermore, one end of the fastener abuts against the connecting screw.

[0013] Further, the connecting assembly includes a rotating shaft, the rotating shaft is rotatably connected to the inside of the connecting seat, and a limiting ring is installed at the bottom end of the rotating shaft, so that the rotating shaft can drive the limiting ring to rotate on the XY plane;

[0014] The upper end of the rotating shaft is hinged with an anchor seat through a hinge shaft, and the anchor seat can rotate on the ZX plane.

[0015] Furthermore, a through hole for a plug to pass through is provided inside the anchor seat along the X-axis direction for connection with a cable.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0017] 1. The bridge cable anchoring structure drives the connecting ring to rotate on the outside of the connecting screw by rotating the connecting driving rod. Through the threaded connection between the connecting ring and the connecting screw, when the connecting ring rotates, the distance between the connecting seat and the connecting screw can be adjusted, and the tightness of the pull rope can be adjusted at the same time, so that the pull rope is in a taut state.

[0018] 2.

[0025] In actual use, the connection holes on the base 1 are connected to the embedded bolts on the stiffening beam, and then the base 1 is fixed to the stiffening beam, and then connected to the cable through the connecting component 4, and the tightness of the cable is adjusted by rotating the rotating part 3.

[0026] In detail, in order to facilitate the adjustment of the tightness of the cable, the rotating member 3 in this embodiment includes a connecting ring 301, at least two driving rods 302 and a connecting seat 303;

[0028] During actual use, the connecting drive rod 302 is rotated to drive the connecting ring 301 to rotate on the outside of the connecting screw 2. Through the threaded connection between the connecting ring 301 and the connecting screw 2, that is, when the connecting ring 301 rotates, the distance between the connecting seat 303 and the connecting screw 2 can be adjusted, and the tightness of the pull rope can be adjusted at the same time, so that the pull rope is in a taut state.

[0029] It should be noted that, in order to ensure that the distance between the connecting seat 303 and the connecting screw 2 can be effectively adjusted, the connecting ring 301 and the connecting seat 303 in this embodiment retain the length of a connecting screw 2.

[0030] During actual setting, the connecting ring 301 is first rotated to be close to the upper end of the connecting screw rod 2, and then the connecting assembly 4 is connected to the cable.

[0031] Furthermore, in order to achieve a locking effect on the connecting ring 301 , in this embodiment, a fastener 304 is threadedly connected to the connecting ring 301 , and one end of the fastener 304 abuts against the connecting screw 2 .
