Description

Technical Field

[0001] The utility model relates to a visible anchoring structure of a cable, in particular to a visible anchoring structure with simple structure and good sealing performance. Background Art

[0002] The parallel wire cable in a bridge cable mainly consists of an outer sheath and an inner wire bundle. At the end of the cable, anchoring is required. At the anchoring end, the sheath of the cable body is removed, and the wire bundle is dispersed. The wire bundle is dispersed in a conical shape for anchoring. The structure of the anchoring end usually consists of a connecting cylinder, an inner cavity conical anchor, a locking nut, and other wire anchoring fittings. Monitoring the anti-corrosion situation in the anchoring area is one of the important tasks in bridge maintenance. To ensure the rigidity and corrosion resistance of the anchoring, components such as the connecting cylinder and the inner cavity conical anchor in the anchoring structure are usually made of steel and do not have visibility. If it is necessary to check the anti-corrosion situation in the anchoring area, cumbersome disassembly and assembly procedures need to be performed, and the operation intensity is high. Therefore, developing a visible anchoring structure for cables is an important research and development content for those skilled in the art.

[0003] Patent Publication No. CN211256630U discloses an intelligent beam end seal waterproof cap structure for a stay cable that can be inspected, which is arranged at the front end pipe orifice of a waterproof cover. It includes a waterproof cap body. The waterproof cap body is of a two-piece or multi-piece combined type. A stepped hole is provided on the inner peripheral wall at the rear end of the waterproof cap. The front end of the waterproof cover extends into the stepped hole, and a first sealing ring is arranged in the axial gap between the stepped hole and the waterproof cover. A third sealing ring is provided at the front end of the waterproof cover. A second sealing ring is arranged on the inner peripheral wall of the waterproof cap body. Multiple annular ribs are arranged on the contact surface of the second sealing ring facing the cable body. Under the tightening action of the waterproof cap body on the second sealing ring, the multiple annular ribs are deformed to tightly hold the cable body circumferentially. And a visible window is provided on the waterproof cap body. The waterproof cap of the utility model can effectively seal the front end of the waterproof cover, play a reliable protection role, and at the same time facilitate the observation of the internal service condition of the waterproof cap.

[0004] In the prior art, a visible window is provided on the waterproof cap body. The visible window is locally provided on the waterproof cap body, and the splicing edge between the visible window and the waterproof cap body serves as a new sealing position, which increases the processing difficulty of the waterproof cover and also increases the risk of sealing failure.

[0017] As Figure 1 shown, in this embodiment, taking a sling as an example, the visible anchoring structure at the end of the cable is described. The outer layer of the cable body 4 of the sling is a sheath layer, and the inside is steel wires 5. The sheath layer at the end of the cable body is removed to expose the steel wires, which pass through the visible waterproof cover 2 successively, and the steel wires are tapered and dispersed and anchored in the anchor 1. The state of the internal steel wires can be directly observed through the visible waterproof cover 2.

[0018] The visible anchoring structure specifically includes an anchor 1, a visible waterproof cover 2, a closed outer cover 3, a washer 6, and a silicone waterproof cover 7. The visible waterproof cover 2 is arranged at the front end of the anchor 1, and the closed outer cover 3 is arranged outside the visible waterproof cover 2. The closed outer cover 3 is fixed to the cable body by a detachable structure and can slide back and forth along the cable body to shield or expose the visible waterproof cover 2 after the fixing structure is released.

[0019] The visible waterproof cover 2 is a through-visible structural member made of a transparent material, and its rear end is hermetically connected to the end of the anchor 1, and its front end is hermetically connected to the cable body 4.

[0020] The visible waterproof cover 2 and the closed outer cover 3 are conical. The closed outer cover 3 is supported outside the visible waterproof cover 2. The closed outer cover 3 is a structural member made of a light-blocking material, and the front end of the closed outer cover 3 is hermetically connected to the cable body 4: A washer 6 is arranged on the surface of the cable body 4, and the washer 6 is located in front of the visible waterproof cover 2. The front end of the closed outer cover 3 is stuck on the washer 6 to play a role of transition and positioning for the closed outer cover 3. A silicone waterproof sleeve 7 is wrapped on the outer surface of the washer, and the front end of the closed outer cover 3 is covered inside the silicone waterproof sleeve 7.
