Abstract

The utility model provides a steel wire rope for a harbor crane. The steel wire rope comprises a center strand, six inner layer strands and eight outer layer strands. The six inner layer strands are wrapped and twisted around the center strand in a spiral mode, the eight outer layer strands are wrapped and twisted around the six inner layer strands in a spiral mode, and the center strand, the inner layer strands and the outer layer strands are formed by wrapping and twisting of a plurality of strands of ropes in a spiral mode. According to the steel wire rope for the harbor crane, through reasonable combination of significant strand numbers and steel wires, overall performance of the steel wire rope is improved, and the steel wire rope has the advantages that load carrying capacity is strong, and service life of the steel wire rope is prolonged.

Description

The portal crane steel wire rope

Technical field

The utility model relates to a kind of portal crane steel wire rope.

Background technology

At present the steel wire rope that generally uses of portal crane steel wire rope as 6 * 37,6 * 29F, 6 * 36WS, 18 * 7 isostructural steel wire ropes, exist in varying degrees that the early fatigue fracture of wire is not wear-resisting, steel cable is partially hard, thereby affect the service life of steel wire rope, increased the cost that uses.This product that the utility model relates to has been done improvement to steel wire rope commonly used, combine the advantage of 6 strands and multiply linear contact lay wire rope, take full advantage of the characteristics of point-contact lay wire rope, the good characteristics of these steel wire ropes had both been kept, improve again their weak point, improved steel wire rope anti-wear performance and softness, thereby improved the service life of steel wire rope.

The utility model content

For solving above technical problem, the utility model provides following technical scheme: a kind of portal crane steel wire rope, described steel wire rope comprise a central strand, six roots of sensation internal layer thigh and eight outer layer strand; Six roots of sensation internal layer thigh wraps sth. made by twisting in the shape of a spiral around central strand; Eight outer layer strand are wrapped sth. made by twisting in the shape of a spiral around six roots of sensation internal layer thigh; Described central strand, internal layer thigh and outer layer strand are multiply rope spiral bag sth. made by twisting and form.

Further, described central strand is mainly twisted with the fingers by compound steel silk bag and is formed, and central strand thigh core is a steel wire; The central strand intermediate layer comprises six roots of sensation steel wire, and six roots of sensation steel wire distributing auger is wound around central strand thigh core, and all the circular section is tangent outward with central strand thigh core for the every steel wire in intermediate layer; The central strand skin comprises 12 steel wires, and outer distributing auger is wound around the intermediate layer, and outer field every steel wire is all tangent with the cylindrical that the cross section, intermediate layer forms.

Further, described internal layer thigh is mainly twisted with the fingers by two-layer steel wire bag and is formed, and the thigh core of internal layer thigh is a steel wire; The central strand skin comprises 6 steel wires, and six roots of sensation steel wire distributing auger is around internal layer thigh thigh core, and all the circular section is tangent outward with strand core for outer field every steel wire.

Further, described outer layer strand is mainly twisted with the fingers by four layers of steel wire bag and is formed, and is divided into a strand core, internal layer, inferior skin and skin, and the thigh core of outer layer strand is a steel wire, and internal layer comprises seven steel wires, and seven steel wire distributing auger bags are twisted with the fingers a strand core; Inferior skin comprises 14 steel wires, seven thick wires and seven finer wires, and the alternate layout of thick wire and finer wire, thick wire is placed in recessed position between internal layer two steel wires, and finer wire is line and wraps touchingly the position of twisting with the fingers the steel wire of internal layer projection; Described skin comprises 14 steel wires, and 14 steel wire distributing augers are around inferior skin, and is placed in the recessed position between time outer 14 steel wires.

This portal crane steel wire rope that the utility model relates to, adopt the multifibres multiply to form, central strand is the some contact, the internal layer thigh is the line contact structures of few silk, easily manufactured, guarantee the softness of steel wire rope, outer main strand is adopted the Xi Lushi of multifibres line contact and the combined type that Wa Lin gulps down formula, cover wire is by forming than thick wire, guarantee the ABRASION RESISTANCE of steel wire rope, by the reasonable combination of effective number of share of stock and steel wire, improved the combination property of steel wire rope, the energy bearing load is large, the service life of prolongation steel wire rope.

Description of drawings

Illustrate 1 the utility model portal crane construction of wire rope schematic diagram;

Diagram 2 is schematic cross-sections that the utility model portal crane is used the steel wire rope outer layer strand;

Diagram 3 is schematic cross-sections that the utility model portal crane is used steel wire rope internal layer thigh;

Diagram 4 is schematic cross-sections that the utility model portal crane is used the steel wire rope central strand.

The specific embodiment

As shown in Figure 1, portal crane comprises central strand 1, internal layer thigh 2, outer layer strand 3 with steel wire rope, each layer thigh carries out the helical form bag round central strand 1 to be twisted with the fingers, 6 internal layer thighs 2 be the symmetrical bag of line contact shape twist with the fingers 1,8 outer layer strand 3 of central strand symmetrically, be a contact shape bag and twist with the fingers an internal layer thigh 2.

As shown in Figure 2, time skin of outer layer strand 3 is thick, finer wire quantity equates, be 2 times of steel wire of internal layer number, the cover wire steel wire that time outer thick wire is thicker forms, finer wire be line touchingly respectively bag twist with the fingers the position of steel wire of internal layer projection, cover wire is line and embeds touchingly adjacent twice cover wire recessed positions.

As shown in Figure 3, internal layer thigh 2 cover wires are line contact shape bag sth. made by twisting internal layer thigh thigh core.

As shown in Figure 4, central strand 1 is comprised of two layers of same diameter steel wire, is a contact shape twisting between steel wire and forms.

The specific embodiment described in the utility model does not consist of the restriction to the application's scope; every within the spirit and principle of the utility model design, any modification that one of skill in the art can make, be equal to and replace and within improvement etc. all should be included in protection domain of the present utility model.
