Description

Technical Field

[0001] This utility model relates to the field of rigging technology, specifically a modular and multifunctional rigging connector. Background Technology

[0002] Rigging connectors are key mechanical components used to connect, secure, or switch between various independent parts in lifting and hoisting systems, such as slings, ropes, chains, and hooks. They achieve reliable connections between different rigging systems through standardized interfaces, thus forming a complete lifting or traction system. Their core functions are to safely transfer loads, distribute stress, prevent detachment, and ensure the stability and reliability of connections under complex working conditions. Modern rigging connectors have evolved into modular, combined, and multifunctional designs, supporting rapid assembly and disassembly, flexible combination, and segmented maintenance. They are widely used in industrial hoisting, construction, logistics and transportation, shipping and ports, outdoor rescue, and other fields, and are an important basic component for ensuring the safety of hoisting operations, improving work efficiency, and reducing operating costs.

[0003] While existing modular rigging connectors offer significant advantages in flexibility and economy, they still suffer from considerable technical shortcomings in structural strength and connection stability. Most modular connectors on the market currently rely on simple tenon-and-mortise or threaded connections, lacking additional support and reinforcement structures after modular assembly. This design simplification results in connectors maintaining basic stability under static loads, but their reliability is significantly compromised under complex dynamic conditions.

[0004] When hoisting operations involve lifting, lowering, rotation, or subjecting to dynamic loads such as impact and vibration, the stress at the connection points changes drastically and becomes concentrated. Due to the lack of effective auxiliary support and mechanical dispersion structures, excessive local stress can easily occur at the joint surfaces between modules, leading to loosening of connections, accelerated wear, and even plastic deformation. This lack of stability poses a risk of connection failure and accidental detachment when the rigging system is subjected to excessive force, seriously threatening the safety of the entire hoisting operation. Therefore, a modular, multifunctional rigging connector is proposed to address the aforementioned problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a modular, multifunctional rigging connector that offers advantages such as improved stability during rigging installation. It solves the problem that existing modular connectors primarily rely on single mortise and tenon or threaded connections, lacking additional support and reinforcement structures after modular assembly. This leads to excessive local stress at the interface between modules, causing loosening, increased wear, and even plastic deformation. This lack of stability poses a risk of connection failure and accidental detachment under excessive stress, seriously threatening the safety of the entire hoisting operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A modular, multi-functional rigging connector includes a load-bearing rope and a connecting seat, wherein the outer wall of the load-bearing rope is provided with a modular installation structure;

[0008] The modular installation structure includes a steel cable fixedly connected inside the connector, a hook fixedly connected to the bottom of the steel cable, threaded mounting seats fixedly connected to both sides of the connector, a first threaded rod threadedly connected to the inside of the threaded mounting seat, an mounting rod fixedly connected to the end of the first threaded rod away from the threaded mounting seat, an mounting seat fixedly connected to the end of the mounting rod away from the connector, a second threaded rod threadedly connected to the inside of the mounting seat, a hanging ring fixedly connected to the bottom of the second threaded rod, a third threaded rod threadedly connected to the inside of the mounting seat, a friction pressure plate fixedly connected to the end of the third threaded rod near the second threaded rod, and support rods fixedly connected to both sides of the connector, a support seat fixedly connected to the end of the support rod away from the connector.

[0009] Furthermore, the connecting seat is fixedly connected to the bottom of the load-bearing pull rope, and a groove is provided inside the connecting seat.

[0010] Furthermore, the outer peripheral wall of the third threaded rod is fixedly connected with two rotating handles, which are symmetrically distributed vertically.

[0011] Furthermore, the threaded mounting base has a first threaded groove inside, and the first threaded rod is threadedly connected inside the first threaded groove.

[0012] Furthermore, the support base is semi-circular in shape, and the mounting rod is located inside the support base, with the mounting rod fitting snugly against the support base.

[0013] Furthermore, the mounting base has a second threaded groove inside, and the second threaded rod is threaded into the inside of the second threaded groove. The mounting base also has a rectangular groove inside.

[0014] Furthermore, a third threaded groove is provided on the side of the mounting base away from the mounting rod, and the third threaded rod is threaded into the interior of the third threaded groove.

[0015] Furthermore, the friction plate is movably connected to the outer peripheral wall of the second threaded rod.

[0016] Compared with the prior art, this utility model provides a modular and multifunctional rigging connector, which has the following advantages:

[0017] 1. This modular, multi-functional rigging connector achieves flexible combination and multi-functional expansion by setting up a modular installation structure consisting of threaded rods, mounting rods, and support seats on both sides of the connector. Its core advantage lies in the fact that after installing lifting points such as hanging rings, rotating the third threaded rod drives the friction plate to apply a strong radial clamping force to the hanging rings or connectors, forming effective secondary reinforcement. This design fundamentally solves the problem of insufficient stability in existing modular connectors that rely solely on a single threaded connection. The mechanical locking method greatly enhances the rigidity and vibration resistance of the connection, effectively preventing loosening or slippage under excessive force.

[0018] 2. This modular and multifunctional rigging connector, through the auxiliary support structure composed of support rods and support seats, provides additional mechanical support points for the installation rod, disperses stress concentration at the connection, significantly improves the overall structure's load-bearing capacity and safety factor, and ensures that it remains stable and reliable under heavy loads and dynamic working conditions, combining the convenience of modularity with the safety of structural reinforcement.

[0029] In this embodiment, a hanging ring 10 is fixedly connected to the bottom end of the second threaded rod 9, and a third threaded rod 11 is threadedly connected to the inside of the mounting base 8. A third threaded groove is opened on the side of the mounting base 8 away from the mounting rod 7. The third threaded rod 11 is threadedly connected to the inside of the third threaded groove. Two rotating handles 12 are fixedly connected to the outer peripheral wall of the third threaded rod 11. The two rotating handles 12 are symmetrically distributed vertically. A friction pressure plate 13 is fixedly connected to the end of the third threaded rod 11 near the second threaded rod 9. The friction pressure plate 13 is movably connected to the outer peripheral wall of the second threaded rod 9.

[0030] In this embodiment, support rods 14 are fixedly connected to both the left and right sides of the connecting seat 2.

[0033] First, the connecting seat 2 is fixed to the bottom of the load-bearing rope 1. The steel cable 3 and hook 4 fixed inside it can serve as the basic lifting point. When it is necessary to expand the connection function, the first threaded rod 6 is screwed into the threaded mounting seats 5 on both sides of the connecting seat 2, so that the mounting rod 7 extends outward and is provided with stable support by the semi-circular support seat 15 at the end of the support rod 14. Then, the hanging ring 10 to be connected is put into the mounting seat 8, and the second threaded rod 9 is screwed into the mounting seat 8 for initial connection. Finally, by rotating the rotating handle 12 on the outer periphery of the third threaded rod 11, it is pushed into the mounting seat 8, which drives the friction pressure plate 13 at the end to press tightly against the outer peripheral wall of the second threaded rod 9, thereby forming a strong radial clamping force on the hanging ring 10 and completing the secondary locking reinforcement. The entire structure achieves modular and rapid assembly through threaded connection, and the mechanical locking of the friction pressure plate 13 and the auxiliary support of the support seat 15 together ensure the high stability and safety of the connecting parts under complex stress.
