Description

Technical Field

[0001] This utility model relates to a cable joint head, and in particular to a cable joint head with protection. Background Technology

[0002] A rigging joint, also known as a rigging connector or rigging link, is a device designed to connect wire ropes, chains, or other flexible linear components. It ensures that the rope or chain maintains stable mechanical properties and safety at the connection point, guaranteeing smooth lifting, towing, and other operations. It is a commonly used and crucial connecting device on ships.

[0003] The commonly used cable joints on ships are open joints, where two wire ropes are connected by a shackle. One end of the joint is a hollow cone to insert into the end of the steel cable, and then molten lead alloy is cast and fused together. This connection has many large gaps, and the shackle protrudes, increasing the risk of it becoming entangled, colliding, or jammed with other objects. For example, when offshore wind power construction vessels are deploying or retrieving anchors, the steel wire rope used for traction on the anchor needs to be wound into the winch on the deck after anchoring. Its joint often gets stuck on the protruding part of the ship's side, which may not only affect the smoothness of operation but also pose a safety hazard to equipment and personnel. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a cable joint head with protection, which not only improves the stability and safety of the connection, but also greatly facilitates on-site installation and disassembly.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A protected cable joint head includes an upper cable joint head and a lower cable joint head. The upper cable joint head and the lower cable joint head are connected in series by shackles and pins to form a connecting body. The connecting body is covered with an outer shell, and the two ends of the outer shell have through holes for flexible connectors connected to the connecting body to pass through.

[0007] The upper cable joint and the lower cable joint have the same structure, both including a conical head. The large end of the conical head is integrated with the connector, and the connector has an interface that matches the shackle.

[0008] The shackle is a U-shaped part with a pin hole at one end. The pin passes through the pin hole and the interface of the upper or lower cable joint to achieve a series connection.

[0009] The outer shell has a spindle-shaped structure.

[0010] The outer shell is composed of two halves, which are locked together by bolts.

[0011] The outer shell is made of cast steel.

[0012] The thickness of the outer shell is between 0.5cm and 2cm.

[0013] This utility model provides a protected cable joint head, which has the following technical effects:

[0014] 1) Simplified connection process: The design of shackles and pins greatly simplifies the connection process of the cable joint head and improves work efficiency.

[0015] 2) Improved safety: The robust connection design and easy-to-operate pin locking mechanism effectively reduce the risk of loosening or falling off the connection, thus improving construction safety.

[0016] 3) Easy to install and disassemble on site: All components are designed to be easy to carry and operate, facilitating quick installation and disassembly at offshore construction sites.

[0017] 4) Enhanced structural strength: The addition of components such as the outer shell and through bolts further enhances the structural strength of the connecting device, improving its ability to withstand external forces. Furthermore, the rounded outer shell prevents entanglement with other objects, thus avoiding jamming of the wire rope during movement, significantly reducing wear and tear at the connection points, and greatly ensuring operator safety.

[0025] like Figure 1-3 As shown, a protected cable joint head includes an upper cable joint head 1, a shackle 2, a pin 3, a lower cable joint head 4, a housing 5, a bolt 6, and a pin hole 7.

[0026] The upper cable joint 1 and the lower cable joint 4 have the same structure, both including a conical head 8, which is connected to the wire rope to be connected. The larger end of the conical head is integrated with the connector 9, which has an interface that matches the shackle 2 for quick connection.

[0027] The shackle 2 is a U-shaped component made of cast steel, possessing high strength and wear resistance. The shackle 2 has a pin hole 7. One end of the shackle 2 is connected in series with the upper cable joint 1 or the lower cable joint 4, and the other end is connected in series with the lower cable joint 4 or the upper cable joint 1 via a pin 3, thus effectively connecting the upper cable joint 1 and the lower cable joint 4. The pin 3 is designed for easy insertion and removal while preventing accidental dislodgement.

[0028] The outer shell 5 has a spindle-shaped structure, which wraps around the key connection parts, serving to protect and enhance the structural strength. The design of the spindle-shaped outer shell takes corrosion resistance into account and forms an arc-shaped shell to avoid entanglement with other objects and reduce wear.

[0029] The outer casing 5 consists of two halves, left and right, which are tightly connected by bolts 6. This facilitates disassembly and installation.

[0030] The thickness of the outer shell 5 is between 0.5cm and 2cm. Different specifications of cable joint heads have different sizes, and the size of the outer shell 5 selected varies, resulting in different thicknesses. The selection should be based on actual needs to ensure sufficient strength and rigidity.
