Description

旋转杆连接件 技术领域
本发明属于连接件技术领域，涉及一种旋转杆连接件，适用于需要进行连接加长并进行旋转工作的作业。
背景技术
旋转杆是指在工作过程中需要进行旋转作业的长条状直杆，比如石油勘探行业，建筑行业，天然气开采行业，采矿行业中不同程度的均需要用到上述的旋转杆，当旋转杆呈垂直作业时，通常称之为钻杆，由于同一根钻杆无法到达需要的深度，因此需要把不同的钻杆进行连接作用。现有技术的钻杆连接通常采用螺纹连接，考虑到螺纹连接处是最薄弱的地方，会在连接处进行加厚或敦厚，这种连接方式能提高一定的强度，但是当钻杆进行多段连接时，往往会在连接处发生弯曲，影响作用。为了改变这种情况，人们采用卡接的方式对钻杆进行连接，并在卡接处用抱箍紧固提高卡接强度，目的是为了在钻杆的正转和反转时，连接处不会发生脱离。但由于抱箍随连接处的两根钻杆同时转动，对抱箍产生极大的剪切力，长期使用时容易使抱箍受损，从而使钻杆脱离。
人们经过不断的探索，提出了各种各样的解决方案，如中国专利文献公开了一种钻杆连接件[公告号：CN 203035110 U]，包括连接轴和连接盘，所述连接轴和连接盘中心均开有通孔，所述连接轴下端连接有安装轴，安装轴最下端在圆周面处设有凹形的键槽，所述连接盘在通孔内设有与键槽相匹配的凸形键结构，所述连接轴和连接盘通过键槽以及凸形键结构配合连接成整体结构。
上述方案的导向性好而且能很好的保护钻杆。在使用时，连接轴与连接盘通过键槽结构彼此配合连接，定位螺钉穿过定位螺孔和螺纹通孔将二者轴向固定，连接轴上端与钻杆传动结构固定连接，钻杆穿过连接轴和连接盘内的通孔，钻杆一部分与连接盘通孔内的结构相匹配，钻杆相应部分与连接盘通孔内结构配合后通过夹紧装置固定夹紧，这样钻杆就在连接轴和连接盘的带动下转动工作。由此我们可以知道，钻杆的是需用通过夹紧装置才能实现连接的，因此在实际使用时有诸多不便，不适合推广应用。
发明内容
本发明的目的是针对上述问题，提供一种结构简单、连接可靠的旋转杆连接件。
为达到上述目的，本发明采用了下列技术方案：一种旋转杆连接件，包括第一旋转杆和第二旋转杆，所述的第一旋转杆和第二旋转杆卡接配合，所述的第一旋转杆上套设有具有内螺纹的紧固螺母，第二旋转杆端部具有外螺纹，内螺纹与外螺纹相匹配，当第一旋转杆和第二旋转杆往相互远离的方向运动时，所述的第一旋转杆能与紧固螺母贴紧从而驱动紧固螺母沿着与第二旋转杆相螺紧的方向旋转。
在上述的旋转杆连接件中，所述的第一旋转杆上具有限位机构，当紧固螺母套设在第一旋转杆上时，所述的限位机构能阻止紧固螺母脱离第一旋转杆，且当第一旋转杆和第二旋转杆往相互远离的方向运动时，限位机构能压紧紧固螺母从而驱动紧固螺母沿着与 第二旋转杆相螺紧的方向旋转。

在上述的旋转杆连接件中，所述的支撑横梁沿第一旋转杆的轴心线周向均匀设置，所述的防松槽与支撑横梁一一对应。

具体实施方式
下面结合附图和具体实施方式对本发明做进一步详细的说明。
如图1、图2和图3所示，一种旋转杆连接件，包括第一旋转杆10和第二旋转杆20，所述的第一旋转杆10和第二旋转杆20卡接配合，所述的第一旋转杆10上套设有具有内螺纹31的紧固螺母30，第二旋转杆20端部具有外螺纹21，内螺纹31与外螺纹21相匹配，当第一旋转杆10和第二旋转杆20往相互远离的方向运动时，所述的第一旋转杆10能与紧固螺母30贴紧从而驱动紧固螺母30沿着与第二旋转杆20相螺紧的方向旋转。
本发明的工作原理是：当第一旋转杆10和第二旋转杆20往相互靠近的方向运动时，由于第一旋转杆10和第二旋转杆20卡接配合，因此不会相互脱离；当第一旋转杆10和第二旋转杆20往相互远离的方向运动时如第一旋转杆10往上运动，而第二旋转杆20还处于原位，为了使第一旋转杆10和第二旋转杆20同步运动，第一旋转杆10和第二旋转杆20之间必然不能出现空隙或自由行程，否则将无法实现同步转动甚至导致第一旋转杆10和第二旋转杆20脱离，本发明提供的紧固螺母30在第一旋转杆10往脱离第二旋转杆20的方向运动时，紧固螺母30能贴紧第一旋转杆10并与第一旋转杆10同向旋转，而旋转过程恰好是内螺纹31与外螺纹21相互螺紧的过程，在这个过程中，紧固螺母30与第二旋转杆20螺接固定，紧固螺母30与第一旋转杆10贴紧，因此紧固螺母30起到桥梁作用，保持第一旋转杆10和第二旋转杆20的连接。至于内螺纹31、外螺纹21和旋转方向的配合，是本领域技术人员的公知常识，只需在工作时将第一旋转杆10与第二旋转杆20相互远离时的旋转方向与内螺纹31和外螺纹21的螺紧方向一致即可。
具体的说，第一旋转杆10上具有限位机构11，当紧固螺母30套设在第一旋转杆10上时，所述的限位机构11能阻止紧固螺母30脱离第一旋转杆10，且当第一旋转杆10和第二旋转杆20往相互远离的方向运动时，限位机构11压紧紧固螺母30从而驱动紧固螺母30沿着与第二旋转杆20相螺紧的方向旋转。
更具体的说，限位机构11包括突出第一旋转杆10外壁且呈圆环状的限位环12，所述的紧固螺母30的端部内壁缩小形成呈环形的定位环32，所述的定位环32的内径大于第一旋转杆10的外径而小于限位环12的外径。显然，限位环12也不一定需要环形，只需能挡住定位环32即可。
在工作时，也就是当紧固螺母30套设在第一旋转杆10上时，定位环32和内螺纹31分别位于紧固螺母30的两端，当紧固螺母30套设在第一旋转杆10上时，内螺纹31和定位环32分别位于限位环12的两侧。
如图4-7所示，第一旋转杆10的端部具有沿轴心线方向突出的连接柱41或具有沿轴心线方向凹进的连接孔42，所述的第二旋转杆20的端部具有沿轴心线方向凹进的连接孔42或具有沿轴心线方向突出的连接柱41，连接柱41和连接孔42的形状、大小相匹配，且为柱状。连接柱41的横截面和连接孔42的横截面为非圆形，也就是说，连接柱41的横截面和连接孔42的横截面的中心到边缘的距离不相等，且连接柱41和连接孔42相互匹配，当连接柱41插入到连接孔42中时，连接柱41与连接孔42卡接从而使第一旋转杆10和第二旋转杆20卡接配合并能同步旋转。
连接柱41的横截面为三角形或多边形，所述的连接孔42的横截面为三角形或多边形。为了便于插入到连接孔42中，连接柱41的端部设有倒角。优选方案，连接柱41和连接孔42的横截面为相互匹配的正六边形。
在现有技术中，如钻杆工作时，当需要钻入较深的深度如石油勘探、打桩时，需要将旋转杆进行连接，加长钻杆过程中，第一旋转杆10和第二旋转杆20通常采用抱箍进行固定，以防止两个旋转杆脱离，但是抱箍连接的方式存在的不足之处在于，旋转过程中会对抱箍形成剪切力，会导致抱箍破裂，两个旋转杆脱离，引发安全事故从而致使工作失败。在本发明中，当第一旋转杆10压在第二旋转杆20上时，第一旋转杆10与紧固螺母30是不接触的，不会产生剪切力，而当第一旋转杆10向上提升时，限位环12接触定位环32从而迫使紧固螺母30转动，紧固螺母30与第二旋转杆20螺紧，防止第一旋转杆10与第二旋转杆20脱离，从而使第一旋转杆10与第二旋转杆20同步提升，也就是说，紧固螺母30起到自固定的作用。
实施例2
本实施例与实施例1的结构和工作原理基本相同，不同之处在于，如图8和图9所示，第一旋转杆10和第二旋转杆20中间分别具有空心通道50，且空心通道50连通第一旋转杆10和第二旋转杆20的两端。在空心通道50中可以注入水泥浆等，从而赋予本发明更多的功能，如在钻孔时可以同时制作水泥搅拌桩。
第一旋转杆10上还设有一个当紧固螺母30与第二旋转杆20连接时能对紧固螺母30进行定位从而防止紧固螺母30脱离第二旋转杆20的防松机构60。
防松机构60包括支撑横梁61，所述的支撑横梁61一端与第一旋转杆10可拆卸连接的，可在支撑横梁61的端部固定螺栓64，螺入到第一旋转杆10中，另一端铰接有一根防松杆62，所述的紧固螺母30顶部具有与防松杆62相配适的防松槽63，当防松杆62插入到防松槽63中时，防松杆62的端部能顶住紧固螺母30从而防止紧固螺母松动。
当支撑横梁61有多个时，支撑横梁61沿第一旋转杆10的轴心线周向均匀设置，所述的防松槽63与支撑横梁61一一对应。
在第一旋转杆10下压时，紧固螺母30的螺纹拧紧方向与第一旋转杆10的转动方向是相反的，因此紧固螺母30有可能脱离第一旋转杆10，为了防止脱离，本实施例设计了防松机构60，防松杆62插入到防松槽63中，能够顶住紧固螺母30，也就限制了紧固螺母30的位置。
本实施例的限位机构11与实施例1也略有不同，第一旋转杆10的端部膨大能卡住紧固螺母30，在第一旋转杆10和第二旋转杆20的连接处依然采用连接柱41和连接孔42的结构。
本文中所描述的具体实施例仅仅是对本发明精神作举例说明。本发明所属技术领域的技术人员可以对所描述的具体实施例做各种各样的修改或补充或采用类似的方式替代，但并不会偏离本发明的精神或者超越所附权利要求书所定义的范围。
尽管本文较多地使用了第一旋转杆10、限位机构11、限位环12、第二旋转杆20、外螺纹21、紧固螺母30、内螺纹31、定位环32、连接柱41、连接孔42、空心通道50、防松机构60、支撑横梁61、防松杆62、防松槽63等术语，但并不排除使用其它术语的可能性。使用这些术语仅仅是为了更方便地描述和解释本发明的本质；把它们解释成任何一种附加的限制 都是与本发明精神相违背的。
