Abstract

The invention relates to a self-locking type steel wire rope jointing method and belongs to the technical field of mechanical engineering. According to the scheme, a set of steel wire rope self-locking jointing device is designed and comprises an internally threaded sleeve, two concave conical nuts in the same dimension, two snap springs A, two conical sleeves, two six-groove conical screws, two plugs and two snap springs B; the hardness of the conical sleeves is slightly lower than that of steel wires; steel wire rope heads are sequentially threaded into the concave conical head nuts and the conical sleeves from small-diameter ends, and the ends of the rope heads are kept slightly longer than the six-groove conical screws in the conical sleeves; the rope heads are disassembled into six strands under the condition of fixed length, and the rope heads are slightly bent inwards, forming 90-degree permanent hooks; the six-groove conical screws of which the conical angle is slighter larger than that of the conical sleeves are wedged from the centers of the steel wire ropes; the steel wire ropes are uniformly distributed in the six grooves of the conical screws and tightly wedged, the 90-degree permanently deformed hooks just surround the large-head bottom ends of the conical screws, the conical screws are sealed by the plugs and fixed by the snap springs B, and the steel rope heads are self-locked and fastened; and two groups of rope end conical sleeve components which are qualified after threading arrangement are separately arranged in the same threaded sleeve in a sleeving manner, the concave conical head nuts at the two ends are tightened, the two ends are fixed by the snap springs A, and the jointing of two steel wire ropes is finished.

Description

Self-locking steel cord jointing method

Technical field

The present invention relates to self-locking steel cord jointing method, belongs to field of mechanical technique.

Technical background

Widely, particularly some big power transmission, bridge, machine-building etc. are all for steel wire rope purposes in the industry Multi-field, the joint connection technology of steel wire rope is the technology for being most commonly encountered and using, and joint style has varied, There are bayonet type, soft metal clamping etc., but in terms of big load-carrying in terms of joint, various optional aspect of means mode, is not too It is many.

The content of the invention

To resolve the problems referred to above, the invention provides a kind of self-locking steel cord jointing method.

Self-locking steel cord jointing method, including bayonet type, soft metal clamping etc., it is characterised in that：Design and produce A set of steel wire rope self locking joint device, includes an inside spin sleeve pipe, the recessed vertebra nut of two same specifications, jump ring A, tapered sleeve, Six groove vertebra nails, plug, jump ring B totally 13, tapered sleeve hardness is more slightly lower than steel wire；Steel wire rope end head is suitable by recessed vertebra head nut, tapered sleeve Sequence is penetrated from minor diameter termination, keeps fag end end slightly to grow six groove vertebras nail in tapered sleeve, fixed length split 6 strands, to infolding fag end into 90 ° of permanent deformation crotch, from steel wire rope centre bore the six groove vertebras nail of angle more slightly larger than interior cone angle is wedged, and makes steel wire rope uniform Be distributed in vertebra nail six grooves within, wedging, make 90 ° of permanent deformation crotches just it is compact enclose bag vertebra nail major part end termination, dress Block head, fixed with jump ring B；Another group of end tapered sleeve part is produced with method, an inside spin sleeve pipe is taken, it is qualified that two resistances are installed End tapered sleeve part be inserted in respectively in same screw shell, tighten the recessed vertebra head nut in two ends, fixed with jump ring A；Between external member mutually Constraint, steel cable head is fastened by self-locking, completes the connection for realizing two sections of steel wire ends.

The know-why of self-locking steel cord jointing method is：Using wedge mouth folder self-tightening and locked angle self-locking steel wire in mechanics Rope and the principle of wedge nail, realize that steel cable head, tapered sleeve, six groove vertebras nail are fastened by self-locking, and nut casing sub-assembly can load, constraint Wherein the mature technology of two lock tubes, makes steel wire rope self locking joint device component, and the fine joint manipulations of Jing make, are capable of achieving to complete The joint connection of two sections of steel wire ropes, includes in know-why：Two A in load constraint combination parts, vertebra set combination parts Jump ring 7, two 6, two, recessed vertebra nut tapered sleeve 5, two, six groove vertebras follow closely 4, two nut sleeves of B jump rings 2, of plug 3, two Pipe 1 and two steel wire rope heads 8.

Minor diameter termination of one steel wire rope head 8 sequentially from recessed vertebra nut 6, tapered sleeve 5 is penetrated, steel wire rope head is kept 8 slightly grew six groove vertebras nail 4 in the tapered sleeve 5, split into 6 strands by fixed length, to infolding fag end permanent deformation crotch in 90 °, from steel The centre bore of cord 8 wedges the six groove vertebras nail 4 of angle more slightly larger than interior cone angle, and makes strand wire group be evenly distributed on the six of vertebra nail 4 Within groove, wedging, make 90 ° of permanent deformation crotches just it is compact enclose bag six groove vertebras nail 4 major part end termination, dress plug 3, use B Jump ring 2 is fixed；Another group of end tapered sleeve part is produced with method, an inside spin sleeve pipe 1 is taken, two resistances are installed into qualified end cone External member is inserted in respectively in same screw shell 1, tightens the recessed vertebra head nut 6 in two ends, is fixed with A jump rings 7；Mutually constrain between external member, Steel cable head is fastened by self-locking, completes the connection for realizing two sections of steel wire rope heads 8.
