Abstract
本实用新型涉及一种鸟窝式防冲锚索，是以钢绞线为主体结构的岩土锚固装置，所述钢绞线为高碳高强钢绞线，包括一体设置的锚固段和鸟窝吸能防冲段，锚固段上设置有多个锚固段鸟窝，鸟窝吸能防冲段上设置有多个非锚固段吸能鸟窝，非锚固段吸能鸟窝中空设置，所述非锚固段吸能鸟窝内填充有防冲吸能材料。本实用新型具有以下有益效果：鸟窝吸能防冲段上设置有多个非锚固段吸能鸟窝，非锚固段吸能鸟窝中空设置，在所述非锚固段吸能鸟窝内填充有防冲吸能材料，有效起到吸能抗冲击的作用，确保非锚固段吸能鸟窝内的防冲吸能材料当受到冲击载荷时锚索和防冲吸能材料能够收缩变形，储存变形能，达到吸能的作用，解决锚索在强冲击地压的冲击载荷作用下的破断问题。
Description
技术领域
本实用新型涉及一种鸟窝式防冲锚索，属于矿山及土木工程支护技术领域。
背景技术
锚索，是以钢绞线为主体结构的岩土锚固装置，作为一种支护方式，其优点是强度大，抗拉吨位高，但由于锚索的基本原材料是高碳钢绞线，其缺点是延伸率低，锚索的延伸率通常只有3%-5%，材料的吸收功低，抗冲击性能差，在有冲击地压和大变形的条件下极易破断，因此，在有冲击低压和大变形的的矿井中使用，必须提高锚索的冲击功和变形性能。
实用新型内容
根据以上现有技术中的不足，本实用新型要解决的技术问题是：为解决上述问题，提供一种鸟窝式防冲锚索，鸟窝式防冲锚索就是利用高强度高碳钢绞线作为原材料，通过在鸟窝吸能防冲段增设吸能鸟窝来提高锚索的吸收功。
本实用新型所述的鸟窝式防冲锚索，是以钢绞线为主体结构的岩土锚固装置，所述钢绞线为高碳高强钢绞线，包括一体设置的锚固段和鸟窝吸能防冲段，锚固段上设置有多个锚固段鸟窝，鸟窝吸能防冲段上设置有多个非锚固段吸能鸟窝，非锚固段吸能鸟窝中空设置，所述非锚固段吸能鸟窝内填充有防冲吸能材料。
优选地，所述防冲吸能材料为吸收功在100-500焦耳的橡胶材料或者塑料材料或者或者金属弹性压缩圈。
优选地，所述锚固段鸟窝的个数至少设置有2个，非锚固段吸能鸟窝的个数至少设置有1个。
优选地，采用液压成型的形式，一次成型制成锚固段、鸟窝吸能防冲段、锚固段鸟窝和非锚固段吸能鸟窝。
优选地，所述钢绞线型号为Φ15.4mm、Φ17.8mm、Φ18.9mm、Φ21.6mm、Φ21.8mm和Φ28.9mm煤矿及隧道常用的钢绞线。
优选地，所述锚固段鸟窝和非锚固段吸能鸟窝的大小设计制造的比钻孔小2毫米，这样可以保证锚索在孔中对中，使得树脂在锚索周围均匀分布，从而用较少的树脂用量取得最大的拉拔力。
优选地，所述鸟窝吸能防冲段上套设有垫圈、加强管和与所述鸟窝吸能防冲段配合的用于压紧所述垫圈的索具，垫圈位于加强管与索具之间。
与现有技术相比，本实用新型具有以下有益效果：
本实用新型所述的鸟窝式防冲锚索，鸟窝吸能防冲段上设置有多个非锚固段吸能鸟窝，非锚固段吸能鸟窝中空设置，在所述非锚固段吸能鸟窝内填充有防冲吸能材料，有效起到吸能抗冲击的作用，确保非锚固段吸能鸟窝内的防冲吸能材料当受到冲击载荷时锚索和防冲吸能材料能够收缩变形，储存变形能，达到吸能的作用，解决锚索在强冲击地压的冲击载荷作用下的破断问题。
附图说明
为了更清楚地说明本实用新型具体实施方式或现有技术中的技术方案，下面将对具体实施方式或现有技术描述中所需要使用的附图作简单地介绍。在所有附图中，类似的元件或部分一般由类似的附图标记标识。附图中，各元件或部分并不一定按照实际的比例绘制。
图1为本实用新型具体实施方式的结构示意图。
图中：1、锚固段 2、鸟窝吸能防冲段 3、锚固段鸟窝 4、非锚固段吸能鸟窝 5、索具 6、垫圈 7、加强管。
具体实施方式
下面结合附图对本实用新型做进一步描述：
以下通过具体实施例对本实用新型作进一步说明，但不用以限制本实用新型，凡在本发明精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本实用新型的保护范围之内。
实施例
如图1所示，所述鸟窝式防冲锚索，是以钢绞线为主体结构的岩土锚固装置，所述钢绞线为高碳高强钢绞线，包括一体设置的锚固段1和鸟窝吸能防冲段2，所述锚固段1的一端一体连接有鸟窝吸能防冲段2，锚固段1上设置有多个锚固段鸟窝3，鸟窝吸能防冲段2上设置有多个非锚固段吸能鸟窝4，非锚固段吸能鸟窝4中空设置，所述非锚固段吸能鸟窝4内填充有防冲吸能材料。
本实施例中，所述防冲吸能材料为吸收功在100-500焦耳的橡胶材料或者塑料材料或者或者金属弹性压缩圈；所述锚固段鸟窝3的个数至少设置有2个，非锚固段吸能鸟窝4的个数至少设置有1个；采用液压成型的形式，一次成型制成锚固段1、鸟窝吸能防冲段2、锚固段鸟窝3和非锚固段吸能鸟窝4；所述钢绞线型号为Φ15.4mm、Φ17.8mm、Φ18.9mm、Φ21.6mm、Φ21.8mm和Φ28.9mm煤矿及隧道常用的钢绞线；所述锚固段鸟窝3和非锚固段吸能鸟窝4的大小设计制造的比钻孔小2毫米，这样可以保证锚索在孔中对中，使得树脂在锚索周围均匀分布，从而用较少的树脂用量取得最大的拉拔力；所述鸟窝吸能防冲段2上套设有垫圈6、加强管7和与所述鸟窝吸能防冲段2配合的用于压紧所述垫圈6的索具5，垫圈6位于加强管7与索具5之间。
本具体实施方式的工作原理：在出厂前在非锚固段吸能鸟窝内的防冲吸能材料，鸟窝式防冲锚索的安装过程与传统鸟窝式防冲锚索大致相同，步骤如下：1、岩面清理；2、测量孔位；3、钻孔；4、清孔；5、验孔；6、投送竖直药卷；7、采用风动搅拌器连接锚索搅拌树脂药卷；8、安装索具5和垫圈6。
以上显示和描述了本实用新型的基本原理、主要特征以及本实用新型的优点。本行业的技术人员应该了解，本实用新型不受上述实施例的限制，上述实施例和说明书中描述的只是说明本发明的原理，在不脱离本实用新型精神和范围的前提下，本实用新型还会有各种变化和改进，这些变化和改进都落入要求保护的本实用新型范围内。本实用新型要求保护范围由所附的权利要求书及其等效物界定。
