Abstract
The invention discloses a tensile cable for a crane. The tensile cable is composed of power wire cores, a flexible rubber powder filling layer, a polyester belt and a ceramic silicone rubber sheath. The power wire cores are formed by arranging inflaming-retarding silicone rubber insulation layers on two stranded aluminum alloy conductors in an extruding and wrapping mode, aluminum alloy conductors are arranged on the two stranded aluminum alloy conductors and under the two aluminum alloy stranded conductors respectively, and braided filling and fastening layers are arranged in the gaps in the power wire cores. The polyester belt extrudes and wraps the four power wire cores to form a cable core. A tensile steel wire is arranged among the four power wire cores, and a polyethylene insulation layer is arranged outside the tensile steel wire. The flexible rubber powder filling layer fills the gap among the wire cores. The ceramic silicone rubber sheath extrudes and wraps the cable core. The tensile cable is simple in design, stable in performance and high in structural strength, can meet the tensile property requirement, and is flexible, easy to lay, resistant to fire and high temperature and long in service life.
Description
Technical field
The present invention relates to cable, relate 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 crane cable, 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.
Summary of the invention
For overcoming above-mentioned deficiency, the object of the invention is to provide a kind of crane tensile cable.
The solution of the present invention is as follows: a kind of crane tensile cable, it is made up 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.
Beneficial effect of the present invention: structural design of the present invention is simple, stable performance, structural strength is high, can meet the crane tensile property requirement of cable, and cable softness is easy to lay, fireproof high-temperature resistant, the life-span is long.
