Description

一种填充式线接触结构钢丝绳 技术领域
本发明涉及一种钢丝绳，尤其涉及一种新型的填充式线接触结构钢丝绳。
背景技术
钢丝绳类产品用途十分广泛，不同的使用场合对钢丝绳的性能有不同的要求，因此各种新型的钢丝绳不断涌现，从而带动了钢丝绳产品的不断发展。随着新工艺、新技术、新产品的不断开发，为创造新型钢丝绳类产品提供了坚实的基础。目前钢丝绳的种类从绳股中层与层之间钢丝的接触状态来看，基本分为点接触、线接触、面接触，这种发展趋势是使得钢丝绳的承载能力逐渐加大，但是所有钢丝绳的生产流程都是先拉丝，在捻股，最后将不同接触状态的股子合绳生产为成品。从相同直径的钢丝绳截面积来看，线接触钢丝绳的接触面积远大于点接触，相应的钢丝绳密度系数高，在其他条件形同的情况下，线接触钢丝绳的强度损失要比点接触钢丝绳的强度损失小。因此在承载能力方面，一般线接触钢丝绳要比点接触钢丝绳提高8-10％。而面接触钢丝绳由于接触面积进一步增加，钢丝绳密度系数更高，承载能力和使用寿命也更高，但由于面接触钢丝绳生产工艺复杂，而且对于钢丝绳使用工况要求严格，并不是所有要求承载能力高的使用场合都可以选择使用面接触钢丝绳。对于一些要求钢丝绳直径不变，承载能力进一步提高，同时钢丝绳表面还需要有一定的与橡胶、聚氨酯等结合使用的钢丝绳来说，进一步提高钢丝绳的密度系数，通过不同的钢丝绳结构设计来实现，如平行密实捻结构或者新型发明的填充钢丝式线接触结构。本发明的带有填充钢丝或者钢丝股或者部分钢丝和部分钢丝股的结构，这种结构在目前的各种钢丝绳结构标准中未有体现。
发明内容
针对现有技术存在的缺陷，本发明的目的在于提供一种新型的填充钢丝线接触钢丝绳结构和生产方法。
实现本发明的目的采用的技术方案为：一种新型填充钢丝线接触钢丝绳，它包括绳芯、绳股、和填充钢丝或者填充钢丝股或者部分填充钢丝部分填充钢丝股，绳芯和绳股均为线接触股，绳股和填充钢丝或者填充钢丝股或者部分填充钢丝部分填充钢丝股一次成型捻制在绳芯上，在绳芯和绳股之间的空隙填充具有一定单丝抗拉强度的填充钢丝或者填充钢丝股或者部分填充钢丝部分填充钢丝股，且在合绳过程中，需要经过特殊定做的工装夹具使绳股和填充钢丝或者填充钢丝股或者部分填充钢丝部分填充钢丝股同步导入合拢点，一次捻制成成品。
本发明与现有技术相比具有的优点是：现有的线接触结构产品，平行密实捻已经是填充系数很高的结构，而采用填充钢丝替代平行密实捻，更加提高了钢丝绳的密度系数，在一定钢丝抗拉强度的情况下，同等直径设计的产品，新型结构可以增加3-5％的填充面积，相应的提高3—5％的破断拉力，同时由于这种新结构的稳定性，对于整绳破断拉力的提高贡献可以达到10-15％，因此这种新型结构不仅仅是可以提供填充面积，提高钢丝绳的密度稀疏；更为关键的用这个结构生产的钢丝绳，不仅仅是填充系数得到提高，钢丝绳整体破断拉力上升，更为重要的是，这种填充结构对整个钢丝绳的结构稳定很有贡献，从目前试验的几个结构规格来看，可以额外提高整绳破断拉力8-10％。实际上由于结构稳定行的贡献，整绳破断拉力可以提高10-15％。

上述实施例的填充式线接触结构钢丝绳的生产方法，步骤一、步骤二的捻向，可以相同、可以相反，不影响本发明的技术效果。
上述实施例的填充式线接触结构钢丝绳，“绳芯和绳股”与“填充钢丝或者填充钢丝股或者部分填充钢丝部分填充钢丝股”，三者之间可以是相同单丝抗拉强度，也可以是不同单丝抗拉强度，即只要绳芯和绳股之间的空隙填充具有一定单丝抗拉强度填充钢丝或者填充钢丝股或者部分填充钢丝部分填充钢丝股，均可以达到本发明的技术效果。
当然，本发明实施例的关于填充钢丝或者钢丝股最优方案：一定强调的是和面股钢丝具有相同钢丝强度级别，能够更加有利于使得中心股的支撑稳定，推迟在生产使用或者检测整绳破断过程中的中心股断裂时间，从而提高了钢丝绳的整体破断拉力，起到了钢丝绳结构更加稳定的作用。
同样道理，本发明实施例采用填充钢丝或者填充钢丝股，提高了钢丝绳的密度系数，最优方案在相同钢丝抗拉强度的情况下，同等直径设计的产品，新型结构可以增加3-5％的填充面积，相应的提高3—5％的破断拉力。但是由于填充钢丝或者填充股对于钢丝绳结构稳定性的贡献，在实际使用或者检测过程中，钢丝绳结构更加稳定，可以提高3-5％的破断拉力，因此该结构对于钢丝绳的破断拉力来说，可以提升8-10％。
以上所述仅为本发明之较佳实施例而已，并非以此限制本发明的实施范围，凡熟悉此项技术者，运用本发明的原则及技术特征，所作的各种变更及装饰，皆应涵盖于本权利要求书所界定的保护范畴之内。毫无疑问的是，本发明实施例优化方案中虽然强调了和面股钢丝具有相同钢丝强度级别的填充钢丝或者填充钢丝股或者部分填充钢丝部分填充钢丝股具有最佳的效果，但是具有一定单丝抗拉强度的所述填充钢丝或者填充钢丝股或者部分填充钢丝部分填充钢丝股同样具有本发明的突出的、显著的效果，也同样属于本发明权利要求书的保护范围之内。
