Abstract
The utility model discloses a crane-used tension cable comprising power wire cores, a flexible rubber powder filling layer, a polyester belt and a ceramic silicone rubber sheath; the power wire core is formed by a flame retardation silicone rubber insulating layer extruding on two layers of aluminium alloy twisted conductors; an aluminium alloy conductor is respectively arranged on an upper side and a lower side of the two layers of aluminium alloy twisted conductors; a braiding filling fasten layer is arranged in a gap of the power wire core; four power wire cores are extruded by the polyester belt so as to form a cable core; a tension steel wire is arranged in middle of the four power wire cores and wrapped by an polyethylene insulation layer; the flexible rubber powder filling layer is arranged in a gap of the wire cores; the ceramic silicone rubber sheath extrudes outside the cable core. The cable is simple in structural design, stable in performance, high in structural intensity, can satisfy tension performance requirements of the crane-used cable, is soft and easy to lay, flameproof, high temperature resistant, and long in service life.
Description
Technical field
The utility model relates to cable, relates in particular to a kind of crane tensile cable.
Background technology
Existing crane cable unstable properties, structural strength is not high, and especially tension requires to meet the requirement of cable for crane, easily occurs that cracking is damaged, causes scrapping of cable, and fireproof high-temperature resistant performance is also bad, and the life-span is short, and cost is high.
Utility model content
For overcoming above-mentioned deficiency, the utility model object is to provide a kind of crane tensile cable.
Scheme of the present utility model is as follows: a kind of crane tensile cable, it is comprised of power core, flexible rubber powder packed layer, polyester belt and ceramic silicone rubber jacket, described power core is to be extruded on two-layer aluminium alloy stranded conductor and to be formed by flame-proof silicon rubber insulating barrier, two-layer aluminium alloy conductor respectively arranges an aluminium alloy conductor up and down, is provided with braiding and fills fastened layer in the gap of power line in-core; It is cable core that described polyester belt extrudes four power cores, in the middle of four power cores, is provided with a tension steel wire, and tension steel wire is outside equipped with polyethylene layer; In gap in described core, be provided with flexible rubber powder packed layer; Described ceramic silicone rubber jacket is extruded in outside cable core.
The beneficial effects of the utility model: the utility model structural design is simple, stable performance, structural strength is high, can meet the tensile property requirement of cable for crane, and cable softness is easy to lay, fireproof high-temperature resistant, the life-span is long.
Accompanying drawing explanation
