Fiber rope quick connecting piece and connection method

Abstract

The invention provides a fiber rope quick connecting piece and a connection method. The connecting piece comprises a spiral fastener, an elastic fastener, a sliding key and a connector. the connector is cylindrical, an inner circle stair is arranged in the middle of the inner wall of the connector, the diameter of the inner circle stair is equal to the outer diameter of a fiber rope, an internal thread is arranged at one end of the connector, the internal thread is connected with an external thread of the spiral fastener, the other end of the connector is provided with holes, and the number of the holes is equal to that of braiding strands of a fiber noose. The connecting piece is used for producing a rigging, and the fiber noose is inserted and braided, the elastic fastener is tightened first, and friction force is gradually increased along with pressing of the fiber noose. Compared with the prior art, the method can be used for quickly connecting two fiber ropes in a non-inserted and non-braided mode, the connected fiber ropes have the strength same as a fiber rope, and the fiber rope can be easily lengthened or manufactured into a rope loop. The quick connecting piece can be used for manufacturing a quick connection fiber rigging, the rigging can adjust the connection position in a large range, or a plurality of clip joints are arranged on one fiber rope.

Description

technical field [0001] The invention relates to the field of rigging manufacturing, in particular to a fiber rope quick connecting piece and a connecting method. Background technique [0002] In recent years, with the introduction of a number of new materials such as ultra-high molecular weight polyethylene, fiber rigging has become more and more widely used, especially in the fields of marine towing and mooring. The fiber material is light, high strength, soft and not easy to damage the workpiece, and it is resistant to most acids and alkalis, common lubricating oils, dirt, and maintenance-free, and is well received by users. At present, in the whole rigging market, the voice of using fiber rigging to replace heavy steel wire rope rigging and chain rigging is getting stronger and stronger, especially the binding rigging, which is light, soft and high strength has become an inevitable development trend. [0003] However, in the current market, there are not many ways to mak...

AI Technical Summary

Problems solved by technology

This kind of rigging has low structural strength at the connection node of the fiber rope, which is far lower than the tensile structural strength of the fiber rope itself; even if some connection structures have relatively high strength, in the actual use process, the operation is cumbersome , cannot achieve high efficiency
