Description

硬岩取芯钻头组件 技术领域
本发明涉及一种硬岩取芯钻头组件。 背景技术
硬岩取芯钻头被用于基础工程作业， 其包括牙轮滚刀以及鞍座， 牙轮滚刀为其作业部， 用于在转动时击碎岩石， 达到钻进的目的， 使 用时，牙轮滚刀需要固定安装在鞍座上，实现与动力输出装置的对接， 然而， 现有的牙轮滚刀直接焊在鞍座上， 更换较为复杂。 发明内容
针对现有技术的不足，本发明的目的旨在于提供一种硬岩取芯钻 头组件， 在保证连接强度能够满足使用的前提下， 可实现牙轮滚刀与 鞍座的快速安装和拆卸。
为实现上述目的， 本发明采用如下技术方案：
硬岩取芯钻头组件， 包括牙轮滚刀以及鞍座， 牙轮滚刀包括用于 作业的基部以及与基部一体成型且可拆卸连接在鞍座内的连接部，连 接部的一侧具有一对接斜面，且连接部的宽度由靠近基部的一端向着 远离基部的一端逐渐增大，鞍座内还可拆卸的连接有一固定块， 该固 定块的侧面形成一个与对接斜面匹配贴合的承压斜面，且固定块的宽 度由靠近基部的一端向着远离基部的一端逐渐减小 ,鞍座套设在连接 部和固定块的外部。
鞍座呈两端开口的筒状，在鞍座外部远离基部的一端设置有固定 板， 连接部和固定块分别通过一紧固螺栓连接在固定板上，每一个紧 固螺栓的外侧端部均螺接两个螺母，固定板的边缘具有一被鞍座端部 止挡并用于限定固定板向着靠近基部活动的止位部。
本发明的有益效果在于：
相比于现有技术，本发明能够实现牙轮滚刀与鞍座的快速拆卸和 安装， 提高钻进作业的效率， 同时， 其连接强度较高， 能够满足钻进 作业的要求， 且可标准化。 附图说明
图 1为本发明的结构示意图；
图 2为本发明的安装示意图；
其中： 10、 牙轮滚刀； 11、 基部； 12、 连接部； 1 3、 对接斜面； 20、 鞍座； 30、 固定板； 31、 止位部； 40、 紧固螺栓； 41、 螺母； 42、 螺母； 50、 固定块； 51、 承压斜面。 具体实施方式
下面， 结合附图以及具体实施方式， 对本发明做进一步描述： 参见图 1、 2 , 本发明的硬岩取芯钻头组件包括牙轮滚刀 10和鞍 座 20 , 其中牙轮滚刀 10包括用于作业的基部 11和与基部 11一体成 型的连接部 12 , 连接部 12的一侧具有一对接斜面 1 3 , 且连接部 12 的宽度由靠近基部 11的一端向着远离基部 11的一端逐渐增大，连接 部 12可拆卸的连接在鞍座 20内部。 鞍座 20内还可拆卸的连接有一 固定块 50, 该固定块 50的侧面形成一个与对接斜面 13 匹配贴合的 承压斜面 51, 并且， 固定块 50的宽度由靠近基部 11的一端向着远 离基部 11的一端逐渐减小， 鞍座 20则套接在连接部 12和固定块 50 的外部， 使固定块 50能够与连接部 12并拢。
本发明的鞍座 20呈两端开口的筒状， 连接部 12和固定块 50从 鞍座 20的上部开口装入， 在鞍座 20远离基部 11的一端设置有固定 板 30, 连接部 12和固定块 50分别通过一个紧固螺栓 40连接在固定 板 30上， 紧固螺栓 40的外侧端部螺接有螺母 41和螺母 42, 螺母 42 位于螺母 41的外侧。 固定板 30的边缘形成一个止位部 31, 该止位 部 31被鞍座 20的端部止挡，用于限定固定板 30向着靠近基部 11一 侧活动。 组装时， 固定板 30从鞍座 20 的下部开口装入， 待止位部 31接触鞍座 20的端部时， 将两个紧固螺栓 40分别穿入固定板 30并 与连接部 12和固定块 50连接， 充分的拧紧螺母 41, 锁紧连接部 12 和固定块 50 , 最后再拧紧螺母 42用于防止松动。
由于上述对接斜面 13与承压斜面 51配合产生较大的压紧力，使 得牙轮滚刀 10能够被紧固在鞍座 20上， 安装时， 只需要充分拧紧紧 固螺栓 40即可。 需要更换牙轮滚刀 10, 只要旋出紧固螺栓 40即可。
对本领域的技术人员来说， 可根据以上描述的技术方案以及构 思， 做出其它各种相应的改变以及形变， 而所有的这些改变以及形变 都应该属于本发明权利要求的保护范围之内。
