Abstract

The utility model discloses a steel rope cable with a new structure. A ring buckle of the steel rope cable with a new structure is that two parts which are divided into three sections and one group on a ring neck part crosswise bend and turn on the top of the ring buckle to be twisted backwards to the furcated neck part to form the ring buckle; small sections [11], [12], [13], [14], [15] and [16] which are twisted backwards to the furcated part are respectively and orderly knitted to gaps of small sections [1], [2], [3], [4], [5] and [6] of a main body of an original rope on the neck part of the furcated part. The utility model has the advantages that the head part of each small section which is knitted backwards is skillfully reserved in the rope body of an original wire rope, and no redundant steel wire head is exposed outside; the utility model also has the advantages of smooth surface and firm and reliable connection. When the utility model is used, hands can not be pricked, and surfaces of equipment can not be scratched because the steel wire exposes outwards; in addition, the diameter of the neck part of the steel rope which is knitted is minimum, which is 1.2-1.5 times of the diameter of the original rope. The utility model is especially suitable for lifting in narrow situations and for lifting large-sized equipment with small gaps.

Description

A kind of rope rig of new construction

Technical field

The device that the utility model belongs to lifting, hitching machinery or other need be hung, occasions such as tractive or dead load are used, the rope rig of definite a kind of new construction of saying so.

Background technology

The rope rig, particularly two ends that uses has the rigging of latch closure at present, uses the most extensive.Can be divided into substantially: insert and compile rigging, the fixedly connected rigging of wire rope clip, pressure clamping rigging, casting rigging etc.These riggings respectively have characteristics, and still, in practical application and on-the-spot the use, particularly in the operations such as lifting transportation for the lifting of main equipment and precision equipment, to compile rigging the most general to insert.And owing to insert the outside that a broken steel wire of each shallow bid of steel wire of the rope rig of compiling all is exposed to the steel wire rope body at present, often stab operating personnel and scuffing by the surface of handling (installation) equipment, and cause a lot of construction hidden danger and accident, particularly when handling main equipment location and installation, often because the gap is too small, make the rigging that uses at present not release smoothly, and have to adopt the method for scrapping this root rope rig of cutting off, steel wire rope is taken out, cause the very big waste and the raising of cost.Once there was the people to propose solution at this point, Chinese patent 00216611.9, in the wire rope sling in order to solve difficult to handle problem, and adopted structure at the chuck of the metal of coated outside of otch, though solved the problem of not pricking the hand, but, owing to the existence that adds cover makes originally the diameter with regard to the neck of the rigging of chap further strengthen, and, when the rope rig of strap clamp cover in work with deposit and produce when crooked chuck two ends direct friction in the process, damage is caused on collide with other surfaces of steel wire rope, shorten the service life of rigging, and also increased manufacturing cost.This has not had any difference with the rigging that adopts the pressure clamping, and its use is affected equally.In order to overcome these problems, designer of the present utility model is to construction of wire rope and insert and compile technology and method and insert the woollen yarn knitting structure and done conscientiously research, has proposed design concept of the present utility model and goal of the invention.

Summary of the invention

According to the problem of above-mentioned existence, research and experimental verification through conscientious have proposed design concept of the present utility model and technical solution, goal of the invention just of the present utility model.Goal of the invention of the present utility model provides a kind of rope rig of new construction.The latch closure of this rope rig by be bifurcated at the ring neck two parts of three strands one group intersect at the top of latch closure crooked break-in backward twisted to the neck of bifurcated form latch closure, twisted is to the
