Abstract
The utility model relates to an 8 multiplied by 19S plus 8 multiplied by 7 plus 19W-structured lift wire rope, which is provided with an outer layer of strands, an inner layer of strands and a central strand, the central strand is of a 1 multiplied by 19W structure, the inner layer of strands are stranded around the central strand, and are eight 1 multiplied by 7-structured wire ropes, the outer layer of strands are stranded around the inner layer of strands, and are eight 1 multiplied by 19S-structured wire ropes, and the three layers of strands are in point-linear contact to form the composite wire rope. The outer layer of strands are divided into three layers. Since the central strand of the wire rope adopts the 1 multiplied by 19W structure, filling is fuller, and the wire rope avoids the defect that the fiber core can rot after a slightly long time; since the three layers of strands adopt the multi-wire and multi-strand point-linear contact full-steel core structure, the compactness of the wire rope is increased, the friction coefficient between the strands is decreased, meanwhile, the flexibility of the wire rope is enhanced, the structural elongation of the wire rope is decreased, and the service life is longer. The wire rope passes through a pulley block in a lift, and is mainly used in high-rise and high-speed lifts, and the fatigue resistance and safety factor of the wire rope can be increased.
Description
Technical field
The utility model relates to a kind of 8 * 19S+8 * 7+19W structure elevator wire rope.
Background technology
The general production structure of elevator wire rope is 8 * 19S+IWR or fibre core, the easy stretcher strain easy fracture of fiber in the fibre core structure, and IWR structure steel wire rope hardness is very big, repeatedly the easy fracture of wire of bending operation.For addressing the above problem, " a kind of high-velocity elevator wire rope " (China Patent No. 2007200439688) arranged, and it contains outer layer strand, internal layer thigh and central strand, is staggered layout between outer layer strand and internal layer thigh, central strand constitutes by three strands, and per share central strand forms by the poly-third ethene filament twisting." a kind of elevator wire rope " (China Patent No. 2010206716544), its ground floor bundle parcel central part, second layer bundle parcel ground floor bundle, central part comprises first, second and third steel wire, and first steel wire is four, is cut to circle mutually, second steel wire is outside first steel wire, be located between the 3rd steel wire between second steel wire, first and second layer bundle formed by 8, and be tangent to each other.
Summary of the invention
The purpose of this utility model is at above-mentioned present situation, and it is strong to aim to provide a kind of pliability, bends indefatigability repeatedly, 8 * 19S+8 of long service life * 7+19W structure elevator wire rope.
Implementation of the present utility model is, 8 * 19S+8 * 7+19W structure elevator wire rope, outer layer strand, internal layer thigh and central strand are arranged, central strand is 1 * 19W structure, the outer twisting internal layer thigh of central strand, the internal layer thigh is the steel wire rope of 81 * 7 structures, the outer twisting outer layer strand of internal layer thigh, outer layer strand is 81 * 19S structure steel wire ropes, and the dotted line contact is a composite steel wire rope between three layers of thigh.
The utility model central strand adopts 1 * 19W structure, fills fulllyer, avoids growing rotten shortcoming slightly because of the fibre core time; Adopt the dotted line of multifibres multiply to contact all steel cored structure between three layers of thigh, increase the compactedness of steel wire rope, reduce the coefficient of friction between the strand, improve the flexibility of steel wire rope simultaneously, reduce the construction of wire rope elongation, longer service life.
The utility model passes the assembly pulley in the elevator, mainly uses in high level, express elevator, can improve fatigue performance and the safety coefficient of steel wire rope.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
The utility model is described in detail in detail with reference to the accompanying drawings.
With reference to Fig. 1, the utility model has outer layer strand 3, internal layer thigh 2 and central strand 1.Central strand is 1 * 19W structure, the outer twisting internal layer thigh of central strand.The internal layer thigh is the steel wire rope of 8 strand of 1 * 7 structure, the outer twisting outer layer strand of internal layer thigh, and outer layer strand is 8 strands of 1 * 19S structure steel wire ropes.The dotted line contact is a composite steel wire rope between three layers of thigh.
Three layers of the per share branches of outer layer strand 3, centre are a coarse-wire rope, and 9 steel wire ropes of its outer twisting form the intermediate layer, and 9 steel wire ropes of twisting form skin outside the intermediate layer, i.e. 8 * 19S structure.
With reference to Fig. 1, at 8 strand of 1 * 7 structure steel wire rope of central strand 1 * 19W structure outside twisting, and then at 8 bursts of 1 * 19S structures of outer twisting steel wire rope.Form the NEW TYPE OF COMPOSITE steel wire rope of a dotted line contact at last.
The utility model is filled fuller by the central strand that adopts 1 * 19W structure, avoid because of long slightly rotten shortcoming of fibre core time, adopt the dotted line contact can prolong the service life of steel wire rope simultaneously, reduce the friction between thigh and the thigh, improve the times of fatigue of steel wire rope.
