Description

Technical Field

[0001] This utility model relates to the field of bridge engineering technology, specifically to a corrosion-resistant bridge main cable terminal anchoring mechanism. Background Technology

[0002] In bridge engineering, the main cable terminal anchorage mechanism is the core component connecting the main cable to the bridge tower or anchorage, and its load-bearing capacity and durability directly determine the safety and stability of the bridge.

[0003] Existing anchoring mechanisms are exposed to the natural environment for a long time, facing severe corrosion problems and structural damage risks. Rainwater can easily penetrate into the mechanism through cable gaps and component connection gaps, causing electrochemical corrosion of metal components such as anchor rods, connecting rods, and bolts, resulting in reduced component strength and loose connections. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a corrosion-resistant bridge main cable terminal anchoring mechanism.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A corrosion-resistant bridge main cable terminal anchoring mechanism includes a support base, an anchor rod fixedly provided on one side of the support base, and an anchoring component provided on one side of the anchor rod;

[0007] The anchoring assembly includes a threaded sleeve, which is fitted over the anchor rod and connected to it by threads. A rotating sleeve is fitted over the threaded sleeve and is rotatably connected to the threaded sleeve. A plurality of O-rings are provided on one side of the rotating sleeve, and a cable is connected to one side of each O-ring. A fixed plate is fixedly fitted over the cable, and a movable plate is provided on one side of the fixed plate. A plurality of short bolts are provided between the movable plate and the fixed plate, and a plurality of second nuts are provided on one side of each short bolt. The fixed plate and the movable plate are fixed together by the short bolts and the second nuts. A support ball is fixedly connected to one end of the cable.

[0008] Preferably, a pad is fixedly sleeved on the outside of the O-ring connecting rod, the pad is in contact with the rotating sleeve, and a first nut is threaded onto the outside of the O-ring connecting rod.

[0009] Preferably, a plug is threadedly connected to one side of the rotating sleeve.

[0010] Preferably, a baffle is provided on the outside of the cable, and a first sealing ring is provided at the connection between the baffle and the cable, and the first sealing ring is fixedly connected to the baffle.

[0011] Preferably, the rotating sleeve is externally fixedly fitted with a second sealing ring.

[0012] Preferably, a support ring is fixedly provided on one side of the support base, and two protective covers are sleeved on the outside of the support ring. The two protective covers are connected and fixed together by screws, and the baffle and the support ring are both connected and fixed to the protective covers by screws.

[0013] Preferably, both the baffle and the second sealing ring are in contact with the protective cover.

[0014] Preferably, one of the protective covers has a drainage groove on one side.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model forms an outer protective barrier by setting a protective cover. Combined with the first sealing ring at the connection between the baffle and the cable and the second sealing ring on the outside of the rotating sleeve, it can effectively prevent rainwater, water vapor and other corrosive media from entering the interior of the mechanism. At the same time, the drainage groove on one side of the protective cover can drain the small amount of water that seeps in in time, avoiding the accumulation of water and the formation of a continuous corrosive environment, which greatly improves the corrosion resistance and service life of the anchoring mechanism.

[0017] 2. The combination of fixed and movable clamping plates, along with the tightening effect of multiple sets of short bolts and the second nut, forms a uniform and firm clamping force on the cable. In addition, the support ball at the cable end effectively prevents the cable from slipping under load, further enhancing the connection stability between the cable and the O-ring connector. Furthermore, the O-ring connector is fixed to the rotating sleeve by a pad and the first nut. The pad can distribute the force and avoid local stress concentration. The overall structure can stably bear the load transmitted by the main cable of the bridge, reducing the risk of anchorage failure. Attached Figure Description

[0025] Example

[0026] like Figures 1-4 As shown, a corrosion-resistant bridge main cable terminal anchoring mechanism includes a support base 1, an anchor rod 8 fixedly provided on one side of the support base 1, and an anchoring component provided on one side of the anchor rod 8.

[0027] The anchoring assembly includes a threaded sleeve 9, which is fitted over the anchor rod 8 and threadedly connected to it. A rotating sleeve 10 is fitted over the threaded sleeve 9, rotatably connected to it. Multiple O-rings 13 are provided on one side of the rotating sleeve 10, and a cable 4 is connected to one side of each O-ring. A fixed clamping plate 16 is fixedly fitted over the cable 4. A movable clamping plate 17 is provided on one side of the fixed clamping plate 16. Multiple short bolts 18 are provided between the movable clamping plate 17 and the fixed clamping plate 16. Multiple second nuts 19 are provided on one side of each short bolt. The fixed clamping plate 16 and the movable clamping plate 17 are fixed together by the short bolts 18 and the second nuts 19. A support ball head 20 is fixedly connected to one end of the cable 4. A support ball head 20 is fixedly fitted over the O-rings 13. A pad 14 is in contact with a rotating sleeve 10. A first nut 15 is threaded onto the outside of the O-ring connecting rod 13. First, the end of the cable 4 is passed through the central hole of the O-ring connecting rod 13, so that the support ball 20 at the end of the cable 4 extends completely out of the outside of the O-ring connecting rod 13. Then, the fixing plate 16 is attached to one side of the cable 4, and the arc-shaped groove of the fixing plate 16 is tightly fitted to the surface of the cable 4. Then, the movable plate 17 is correspondingly fastened to the other side of the fixing plate 16, so that the cable 4 is clamped between the arc-shaped grooves of the two. Next, multiple sets of short bolts 18 are passed through the bolt holes of the fixing plate 16 and the movable plate 17 in sequence. Two second nuts 19 are screwed into the end of each short bolt 18. The double nut locking structure prevents the bolts from loosening, thus completing the firm connection between the cable 4 and the O-ring connecting rod 13.

[0028] A plug 11 is threadedly connected to one side of the rotating sleeve 10. The plug 11 is rotatably connected to one side of the rotating sleeve 10 by the thread. The plug 11 can seal the opening at the end of the rotating sleeve 10 to prevent corrosive media from entering from that position.

[0029] A baffle 3 is fitted over the cable 4. A first sealing ring 5 is provided at the connection between the baffle 3 and the cable 4. The first sealing ring 5 is fixedly connected to the baffle 3. A second sealing ring 12 is fixedly fitted over the rotating sleeve 10. A support ring 6 is fixedly provided on one side of the support base 1. Two protective covers 2 are fitted over the support ring 6. The two protective covers 2 are fixedly connected by screws. The baffle 3 and the support ring 6 are both fixedly connected to the protective covers 2 by screws. The baffle 3 and the second sealing ring 12 are both in contact with the protective covers 2. The baffle 3 is fitted over the cable 4 in advance. A first sealing ring 5 is provided at the connection between the baffle 3 and the cable 4. 5. Made of aging-resistant rubber, its inner wall is tightly fitted to the surface of cable 4 to achieve a seal in this area. Then, two semi-circular protective covers 2 are fastened from the outside of the support ring 6 and the baffle 3, so that the support ring 6 is embedded in the annular groove on the inside of the protective cover 2. The outer edge of the baffle 3 is in contact with the port of the protective cover 2, and the second sealing ring 12 outside the rotating sleeve 10 is tightly fitted to the inner wall of the protective cover 2 to further enhance the sealing effect. By passing screws through the flange connection holes of the two protective covers 2, the fixing holes of the baffle 3, and the mounting holes of the support ring 6 in sequence, the protective cover 2 is fixedly connected to the baffle 3 and the support ring 6 respectively, completing the encapsulation of the entire protective cover 2.

[0030] One of the protective covers 2 has a drainage groove 7 on one side, through which water is discharged to prevent water accumulation and corrosion of internal components.

[0031] The usage process of this utility model is as follows:

[0032] The support base 1 is made of high-strength concrete. Its internal steel reinforcement skeleton is fixedly connected to the anchor rod 8 to ensure that the support base can provide a stable support foundation for the entire anchoring mechanism. Before installation, the surfaces of metal parts such as the anchor rod 8, threaded sleeve 9, and O-ring connecting rod 13 need to be treated with rust removal and anti-corrosion coating to further improve the overall anti-corrosion performance.

[0033] Step 1: Fixing the cable to the O-ring connector

[0034] First, pass the end of cable 4 through the center hole of O-ring connecting rod 13, so that the support ball 20 at the end of cable 4 extends completely out of the outside of O-ring connecting rod 13. Then, attach the fixing plate 16 to one side of cable 4. The arc groove of the fixing plate 16 fits tightly with the surface of cable 4. Then, fasten the movable plate 17 to the other side of the fixing plate 16, so that cable 4 is clamped between the arc grooves of the two. Next, pass multiple sets of short bolts 18 through the bolt holes of the fixing plate 16 and the movable plate 17 in sequence. Tighten two second nuts 19 into the end of each short bolt 18. The double nut locking structure prevents the bolts from loosening, thus completing the firm connection between cable 4 and O-ring connecting rod 13.

[0035] Step 2: Assembly and installation of anchoring components

[0036] The O-ring connecting rod 13, with cable 4 assembled, is passed through the mounting hole on one side of the rotating sleeve 10, so that the outer pad 14 of the O-ring connecting rod 13 is in close contact with the inner wall of the rotating sleeve 10. The pad 14 is made of elastic metal material, which can buffer the force and enhance the sealing. Then, the first nut 15 is screwed into the end of the O-ring connecting rod 13 that extends out of the rotating sleeve 10. The first nut 15 is tightened until the pad 14 and the rotating sleeve 10 are tightly fitted, thus fixing the O-ring connecting rod 13 to the rotating sleeve 10. The threaded sleeve 9 is then passed through the other side of the rotating sleeve 10. The threaded sleeve 9 and the rotating sleeve 10 are fitted with a clearance to ensure that the rotating sleeve 10 can rotate freely around the threaded sleeve 9, which facilitates the subsequent adjustment of the cable 4 angle. Then, the plug 11 is connected to one side of the rotating sleeve 10 by threaded rotation. The plug 11 can seal the opening at the end of the rotating sleeve 10 to prevent corrosive media from entering from this position. Finally, the threaded sleeve 9 is aligned with the anchor rod 8 on the support base 1, and the threaded sleeve 9 is rotated to connect with the anchor rod 8 by thread until the threaded sleeve 9 is tightened in place, thus completing the connection between the anchoring component and the support base 1.

[0037] Step 3: Encapsulation and sealing of the protective cover

[0038] The baffle 3 is pre-fitted onto the outside of the cable 4. A first sealing ring 5 is provided at the connection between the baffle 3 and the cable 4. The first sealing ring 5 is made of aging-resistant rubber material. Its inner wall is tightly fitted to the surface of the cable 4 to achieve a seal at this part. Then, two semi-circular protective covers 2 are fastened from the outside of the support ring 6 and the baffle 3, so that the support ring 6 is embedded in the annular groove on the inside of the protective cover 2. The outer edge of the baffle 3 is in contact with the port of the protective cover 2, and the second sealing ring 12 outside the rotating sleeve 10 is tightly fitted to the inner wall of the protective cover 2 to further enhance the sealing effect. The protective cover 2 is fixedly connected to the baffle 3 and the support ring 6 respectively by passing screws through the flange connection holes of the two protective covers 2, the fixing holes of the baffle 3 and the mounting holes of the support ring 6 in sequence, thus completing the encapsulation of the entire protective cover 2.

[0039] Protection and Adaptation Principles During Use: During bridge operation, the protective cover 2, as the outer protective structure, can block most rainwater, dust, and other external impurities. A small amount of rainwater that seeps in will be blocked inside the protective cover 2 by the first sealing ring 5 and the second sealing ring 12. Since the protective cover 2 is set at an angle, the accumulated water will flow along the inner wall to the bottom and be discharged through the drainage groove 7 on one side of one of the protective covers 2, preventing water from accumulating and corroding internal components. The rotating connection structure of the rotating sleeve 10 and the threaded sleeve 9 allows the cable 4 to adjust the direction of force by slightly rotating the rotating sleeve 10 when subjected to dynamic forces such as wind and vehicle loads, reducing stress concentration damage to the anchoring structure and improving the adaptability and stability of the mechanism.

[0040] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
