Abstract

The utility model provides a be used for hoist non -rotating rope, includes wire rope core, inlayer thigh and outer strand, the wire rope core be the hemp center, inlayer thigh and the outer strand of sth. Made by twisting in wire rope to on the contrary, inlayer thigh external diameter is a bit larger tham outer strand inscribed circle diameter, inlayer thigh and outer strand length of lay multiple are between 6.3~6.5. To 728 7+NF of non -rotating rope 17, to twist with the fingers to being right ordinary lay for outer strand, the rope length of lay is 6.5 times, and the inlayer thigh is left lang lay, and the length of lay is 6.3 times, and the wire rope core is left lang lay, and the length of lay is 7 times. The beneficial effect of the utility model: the utility model discloses an ectonexine rope strand is twisted with the fingers to on the contrary, produces a pair of opposite direction's gyroscopic moment. Since the gyroscopic moment opposite direction that the ectonexine thigh produced, cancel each other out for wire rope has little rotation, irrotational characteristics even. Therefore its specially adapted lift by crane the space little, lift by crane big, the single rope of range and lift by crane, require high -speed, steady occasion.

Description

A kind of for crane non-rotating cable
Technical field
This utility model relates to a kind of steel wire rope, particularly relates to one and is applicable to the crane micro-rotation of suspention or does not revolves The steel wire rope turned.
Background technology
Steel wire rope is to be coiled into stock by steel wire, then is coiled into rope by its strand, and at present, steel wire rope product is a lot, existing Applying widely in foundry industry, the requirement to steel wire rope is more and more higher, it is desirable to it is high that steel wire rope has Fracture Force, From heavy and light, good toughness, structural stretch is less, preferable shock resistance and anti-collapse property, and service life is long, Using more in lifting operation is the ordinary steel rope of circular section twisting, because of in its spiral twisting process and structure Restriction, rotation can be produced when it is under tension.The size of the anglec of rotation is directly proportional to rope capacity. The rotation of steel wire rope not only reduces work efficiency, and brings certain danger, even entail dangers to life to operation Property safety.At some different areas of activity, the rotatory of ordinary steel rope is extremely harmful the most unallowed.
Summary of the invention
This utility model is for solving the problems referred to above, it is provided that a kind of Rotation overcoming ordinary steel rope, by two Layer or multilayer strand repeatedly twisting form non-rotating cable.
Technical solution adopted in the utility model:
A kind of for crane non-rotating cable, including wire rope core, internal layer stock and outer layer strand, described wire rope core is Hemp core, described internal layer stock and outer layer strand sth. made by twisting in steel wire rope are on the contrary, and internal layer stock external diameter is slightly larger than outer layer strand Inscribed circle diameter, internal layer stock and outer strands laying pitch coefficient are between 6.3~6.5.
The structure of non-rotating cable is 17 × 7/28 × 7+NF, and outer layer strand is twisted with the fingers to for right ordinary lay, the lay pitch of restricting Being 6.5 times, internal layer stock is left twist-on-twist, and the lay pitch is 6.3 times, and wire rope core is left twist-on-twist, and the lay pitch is 7 times.
The beneficial effects of the utility model: ectonexine rope strand of the present utility model is twisted with the fingers on the contrary, produces a pair direction Contrary turning moment.The turning moment produced due to ectonexine stock is in opposite direction, cancels out each other so that steel wire Rope has micro-rotation, the most non-rotary feature.Thus it is particularly well-suited to lift by crane that space is little, lifting range is big, Single rope lifting, requirement high speed, stable occasion.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1-wire rope core;2-internal layer stock;3-outer layer strand.
Detailed description of the invention
A kind of for crane non-rotating cable, including wire rope core 1, internal layer stock 2 and outer layer strand 3, described Wire rope core 1 is hemp core, described internal layer stock 2 and the outer layer strand 3 sth. made by twisting in steel wire rope on the contrary, internal layer stock 2 External diameter restricts laying pitch coefficient 6.3~6.5 slightly larger than the inscribed circle diameter of outer layer strand 3, internal layer stock 2 and outer layer strand 3 Between.
Concrete, the structure of non-rotating cable is 17 × 7/28 × 7+NF, and outer layer strand 3 is twisted with the fingers to for right mutual Twisting with the fingers, the rope lay pitch is 6.5 times, and internal layer stock 2 is left twist-on-twist, and the lay pitch is 6.3 times, and wire rope core 1 is left twist-on-twist, The lay pitch is 7 times.
