Description

Technical Field

[0001] This invention relates to the field of cable adjustment technology, and in particular to a cable-stayed bridge cable adjustment structure and its adjustment method. Background Technology

[0002] A cable-stayed bridge, also known as a skeletal-stayed bridge, is a type of bridge where the main beam is directly supported by numerous cables to the bridge towers. It is a structural system composed of pressure-bearing towers, tension-bearing cables, and bending-bearing beams. It can be viewed as a multi-span elastically supported continuous beam where cables replace piers. The weight of the cable-stayed bridge is distributed through multiple cables on both sides. During the connection process, the cables on a cable-stayed bridge need to be stretched to an appropriate tension, requiring tension adjustment. At the same time, the cable adjustment parts on a cable-stayed bridge are exposed to the elements for a long time and are susceptible to erosion by rainwater, resulting in rust. Therefore, a cable adjustment structure for cable-stayed bridges is proposed. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a cable-stayed bridge cable adjustment structure and its adjustment method to solve the aforementioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A cable-stayed bridge cable adjustment structure includes an upper bridge cable and a lower bridge cable. An upper connecting plate and a lower connecting plate are fixedly connected to one end of the upper bridge cable and the lower bridge cable, respectively. An adjustment plate is installed on one side of the lower connecting plate through a fixed connection assembly. The adjustment plate and the upper connecting plate are connected by a threaded rotation adjustment assembly. An adjustment fixing assembly is provided on the outer side of the upper connecting plate and the adjustment plate. An upper fixing protective sleeve and a lower fixing protective sleeve are fixedly sleeved on the upper bridge cable and the lower bridge cable, respectively. An adjustment opening assembly is provided between the upper fixing protective sleeve and the lower fixing protective sleeve. A connection sealing assembly is provided on the outer side of the upper fixing protective sleeve and the lower fixing protective sleeve.

[0005] Preferably, the fixed connection assembly includes multiple fixed connection columns fixedly installed on one side of the lower connecting plate, one end of each of the multiple fixed connection columns being fixedly installed on one side of the adjusting plate, and the multiple fixed connection columns being arranged in a circumferential array.

[0006] Preferably, the threaded rotation adjustment assembly includes a threaded adjustment hole on one side of the adjustment disc, a threaded adjustment post is threadedly installed on the threaded adjustment hole, both ends of the threaded adjustment post extend outside the threaded adjustment hole, an anti-detachment disc is fixedly installed at the bottom end of the threaded adjustment post, a convex rotation groove is opened on one side of the upper connecting disc, one end of the threaded adjustment post extends into the convex rotation groove and is fixedly installed on the rotation disc.

[0007] Preferably, a large rotating gear is fixedly sleeved on the threaded adjusting column, a drive motor is fixedly installed on one side of the upper connecting plate, and a small rotating gear is connected to the output end of the drive motor, with the large rotating gear and the small rotating gear meshing.

[0008] Preferably, the adjusting and fixing assembly includes multiple bottom connecting blocks fixedly installed on the outside of the upper connecting plate, multiple top connecting blocks fixedly installed on the outside of the adjusting plate, the multiple bottom connecting blocks and the multiple top connecting blocks being arranged correspondingly, and connecting holes being opened on one side of the bottom connecting blocks and the top connecting blocks, with connecting bolts movably installed in two corresponding connecting holes, and a nut being threaded onto one end of the connecting bolt.

[0009] Preferably, the adjustment opening component includes an annular movable groove formed on one end of the upper fixed protective sleeve, a connecting ring movably mounted on the annular movable groove, a connecting groove formed on one side of the lower fixed protective sleeve, and one side of the connecting ring extending outside the annular movable groove and into the connecting groove.

[0010] Preferably, the outer side of the connecting ring is provided with multiple external connecting grooves, and the outer side wall of the connecting groove is provided with multiple internal connecting grooves. The external connecting grooves and the internal connecting grooves are adapted to each other, and the connecting ring is threadedly installed in the connecting groove.

[0011] Preferably, the connecting sealing assembly includes a middle soft sleeve fitted onto the upper fixed protective sleeve and the lower fixed protective sleeve. The upper fixed protective sleeve has an upper tightening groove, and the lower fixed protective sleeve has a lower tightening groove. Both the upper and lower tightening grooves are located below the middle soft sleeve. The middle soft sleeve has two elastic tightening rings, which are located in the upper and lower tightening grooves, respectively.

[0012] A method for adjusting the cables of a cable-stayed bridge, characterized in that the method includes: Step 1: When adjusting the tension of the upper and lower bridge cables of the cable-stayed bridge, start the drive motor on the rotating thread adjustment assembly. This will drive the small gear to rotate, which in turn will drive the large gear to rotate. This rotation will drive the thread adjustment column to rotate. Under the action of the thread in the thread adjustment hole, the distance between the upper connecting plate and the adjustment plate will be adjusted. After adjusting the distance, the tension of the cable can be achieved. Step 2: After the tension is adjusted, pass the multiple connecting bolts on the adjusting and fixing components through the bottom connecting block and the top connecting block, and finally lock them in place with nuts. This will ensure that the position between the upper connecting plate and the adjusting plate is fixed after adjustment, preventing any movement and making the tension more stable. Step 3: After tension adjustment, rotate the connecting ring on the adjustment opening component and rotate it into the connecting groove. The connecting ring is threaded into the connecting groove, which protects the cable adjustment part and prevents it from entering the equipment. Step 4: The connecting sealing assembly is set up. The middle soft sleeve on the connecting sealing assembly can protect the connection between the upper and lower fixed protective sleeves. It is tightened and fixed by two elastic tightening rings, realizing the sealing connection between the middle soft sleeve and the upper and lower fixed protective sleeves. The connection is not easy for rainwater to seep in, and the sealing performance is good, thus ensuring that the inside is not easy to rust.

[0013] Compared with the prior art, the beneficial effects of the present invention are: In this invention, the cable-stayed bridge cable adjustment structure allows for the operation of a drive motor on the rotating threaded adjustment assembly during tension adjustment of the upper and lower bridge cables. This motor drives the threaded adjustment column to rotate, and the distance between the upper connecting plate and the adjustment plate is adjusted by the thread action of the threaded adjustment hole. After the distance is adjusted, the cable tension is achieved. Once the tension is adjusted, multiple connecting bolts on the adjustment and fixing assembly are passed through the bottom connecting block and the top connecting block, and finally locked with a barrel nut. This ensures that the position between the upper connecting plate and the adjustment plate is fixed after adjustment, preventing movement and making the tension more stable. In this invention, after the tension adjustment is completed, the connecting ring on the adjustment opening component is rotated and rotated into the connecting groove to protect the cable adjustment part, making it difficult for water to enter the equipment. The connecting sealing component, with the soft sleeve in the middle, can protect the connection between the upper and lower fixed protective sleeves, making it difficult for rainwater to seep in and ensuring good sealing, thus preventing internal corrosion.

[0024] In use: When adjusting the tension of the upper bridge cable 1 and the lower bridge cable 2 on the cable-stayed bridge, the drive motor 13 on the rotating threaded adjustment assembly is started, which drives the rotating pinion 14 to rotate. The rotation of the pinion 14 drives the rotating gear 12 to rotate, which in turn drives the threaded adjustment column 8 to rotate. Under the action of the thread in the threaded adjustment hole 7, the distance between the upper connecting plate 3 and the adjustment plate 5 is adjusted. After the distance is adjusted, the tension of the cable can be achieved. The convex rotating groove 10 allows the threaded adjustment column 8 to rotate on the upper connecting plate 3.

This ensures that the position between the upper connecting plate 3 and the adjustment plate 5 is fixed after adjustment and will not shift. The movement makes the tensioning more stable. After the tension adjustment is completed, rotate the connecting ring 23 on the adjustment opening component. The connecting ring 23 moves out from the annular moving groove 22 and rotates into the connecting groove 24. The external connecting tooth groove 25 and the internal connecting tooth groove 26 allow the connecting ring 23 to be threaded into the connecting groove 24, thus protecting the cable adjustment part and preventing it from entering the equipment. The connecting sealing component has a middle soft sleeve 27, which can protect the connection between the upper fixed protective sleeve 20 and the lower fixed protective sleeve 21. Then, two elastic tightening rings 30 are tightened in the upper tightening groove 28 and the lower tightening groove 29 respectively, so as to achieve a sealed connection between the middle soft sleeve 27 and the upper fixed protective sleeve 20 and the lower fixed protective sleeve 21. The connection is not easy for rainwater to seep in, and the sealing performance is good, thus ensuring that the inside is not easy to rust.
