Abstract

本实用新型涉及一种异形电缆芯镀锌钢丝绳,包括电缆芯和拧绕在电缆芯外围的若干个钢丝绳股,在电缆芯和钢丝绳绳股之间填充聚乙烯纤维,特征是:所述电缆芯包括多个径向排列的铜线和纤维线,铜线和纤维线的横截面形状为扇形,铜线和纤维线间隔设置,扇形横截面的顶角一侧朝向圆心使电缆芯的横截面呈圆形。所述铜线和纤维线的设置数目均为2根或3根。组成钢丝绳股的钢丝外表面镀有金属锌。本实用新型的电缆芯表面平整,在钢丝绳股与电缆芯产生移动时,降低压伤压断电缆芯的可能;钢丝绳股受力后,产生径向压力,由于异形电缆芯,铜线表面平面增加,提高了电缆芯的耐压力,从而大大提高了电缆芯钢丝绳的使用寿命。

Description

异形电缆芯镀锌钢丝绳
技术领域
本实用新型涉及一种钢丝绳,尤其是一种异形电缆芯镀锌钢丝绳。
背景技术
镀锌钢丝绳是用于起吊作用的,在使用时,钢丝绳股与电缆芯由于受力后延伸的不一致,产品使用时产生纵向移动的可能,使得电缆芯有被压伤压断的可能,降低了钢丝绳的使用寿命。
发明内容
本实用新型的目的是克服现有技术中存在的不足,提供一种耐压力大的异形电缆芯镀锌钢丝绳。
按照本实用新型提供的技术方案,所述异形电缆芯镀锌钢丝绳,包括电缆芯和拧绕在电缆芯外围的若干个钢丝绳股,在电缆芯和钢丝绳绳股之间填充聚乙烯纤维,特征是:所述电缆芯包括多个径向排列的铜线和纤维线,铜线和纤维线的横截面形状为扇形,铜线和纤维线间隔设置,扇形横截面的顶角一侧朝向圆心使电缆芯的横截面呈圆形。
所述铜线和纤维线的设置数目均为2根或3根。
组成钢丝绳股的钢丝外表面镀有金属锌。
本实用新型的电缆芯表面平整,在钢丝绳股与电缆芯产生移动时,降低压伤压断电缆芯的可能;钢丝绳股受力后,产生径向压力,由于异形电缆芯,铜线表面平面增加,从而降低了钢丝绳股对电缆的单位压强,提高了电缆芯的耐压力,从而大大提高了电缆芯钢丝绳的使用寿命。
附图说明
图1为实施例一的结构示意图。
图2为实施例二的结构示意图。
具体实施方式
下面结合具体附图和实施例对本实用新型作进一步说明。
如图所示:钢丝绳包括钢丝绳股1、聚乙烯纤维2铜线3纤维线4。
实施例一:
本实用新型包括电缆芯和拧绕在电缆芯外围的若干个钢丝绳股1,在电缆芯和钢丝绳绳股1之间填充聚乙烯纤维2;所述电缆芯包括多个径向排列的铜线3和纤维线4,铜线3和纤维线4的横截面形状为扇形,铜线3和纤维线4的间隔设置,扇形横截面的顶角一侧朝向圆心使电缆芯的横截面呈圆形;所述铜线3和纤维线4的设置数目均为2根;组成钢丝绳股1的钢丝外表面镀有金属锌。
实施例二:
本实用新型包括电缆芯和拧绕在电缆芯外围的若干个钢丝绳股1,在电缆芯和钢丝绳绳股1之间填充聚乙烯纤维2;所述电缆芯包括多个径向排列的铜线3和纤维线4,铜线3和纤维线4的横截面形状为扇形,铜线3和纤维线4间隔设置,扇形横截面的顶角一侧朝向圆心使得电缆芯的横截面呈圆形;所述铜线3和纤维线4的设置数目均为2根;组成钢丝绳股1的钢丝外表面镀有金属锌。
本实用新型的电缆芯表面平整,在钢丝绳股与电缆芯产生移动时,降低压伤压断电缆芯的可能;钢丝绳股受力后,产生径向压力,由于异形电缆芯,铜线表面平面增加,从而降低了钢丝绳股对电缆的单位压强,提高了电缆芯的耐压力,从而大大提高了电缆芯钢丝绳的使用寿命。
