Description

打桩机的钻杆保持架 技术领域
本发明属于建筑设备技术领域，尤其是涉及一种打桩机的钻杆保持架。
背景技术
目前，建筑工地上使用的打桩机械有两种：一种的旋转打桩机，这种打桩机的结构是利用卷扬机拉起的钻杆悬挂架，通过通过动力头带动钻杆钻头向地下钻机成孔的打桩设备；另一种是冲击锤打桩机，这种打桩机的结构是利用卷扬机拉起冲击锤反复下落，提升来实现打桩。其中，旋转打桩机在打桩时主要通过钻杆的周向转动来实现向地下钻杆的目的，但是实际施工时由于钻杆的长度较长，周向转动时很难保证钻杆的稳定性，容易出现打摆现象，严重的还会出现钻杆之间相互干扰的情况，这样就给打桩机的施工效果和进度带来极大的影响。
为了解决现有技术存在的问题，人们进行了长期的探索，提出了各式各样的解决方案。例如，中国专利文献公开了一种打桩机的中间减震器[申请号：201410405435.4]，包括一个中间架和一个减震架，中间架上安装有一对夹持架，减震架由前后两个相对设置的减震组件与左右两个相对设置的快拆组件组成，减震组件的内侧均布设置有若干个与打桩机的钻杆相连的轴瓦，设置在前后两个减震组件上的轴瓦之间不相连，中间可以通行转动轴，设置在同一个减震组件上的两个轴瓦之间不相连，其间的间隔空间可以通行保持架。
上述方案在一定程度上解决了现有打桩机钻杆体相互之间易 相互干扰的问题，但是该方案依然存在着：周向转动时很难保证钻杆的稳定性，容易出现打摆现象问题。
发明内容
本发明的目的是针对上述问题，提供一种结构简单合理，能提高钻杆周向转动时的稳定性的打桩机的钻杆保持架。
为达到上述目的，本发明采用了下列技术方案：本打桩机的钻杆保持架，其特征在于，本钻杆保持架包括若干位于同一水平面上的拼合式环形圈，相邻两个拼合式环形圈通过可拆式结构相连，每一个拼合式环形圈内均穿设有钻杆体，在钻杆体与拼合式环形圈之间设有由若干弧形内衬体周向对接而成的环形内衬套，所述的钻杆体与环形内衬套周向转动相连，所述的环形内衬套包括套设于钻杆体周向外侧的衬套体，且所述的衬套体两端分别延伸至拼合式环形圈端部外侧从而形成与拼合式环形圈端部相抵靠且位于钻杆体周向外围的延伸套体。施工时，可以在钻杆体的多个不同位置均设置拼合式环形圈，且各个拼合式环形圈相连，这样可以保证钻杆体周向转动时的稳定性，不易出现摆动现象。
在上述的打桩机的钻杆保持架中，所述的拼合式环形圈由若干弧形体周向合围而成，所述的弧形体周向外侧设有连接条，且相邻两个连接条通过安装螺栓固定相连。
在上述的打桩机的钻杆保持架中，所述的弧形体的数量为四个，且所述的弧形体周向均匀分别设置。
在上述的打桩机的钻杆保持架中，所述的可拆式结构包括分别设置在相邻两个拼合式环形圈上的连接条外侧的安装条，每一个弧形体的端面均与相邻一个弧形体的端面相互抵靠设置，所述的安装螺栓贯穿于安装条且所述的安装条通过安装螺栓与连接条相连。
在上述的打桩机的钻杆保持架中，所述的拼合式环形圈的数量至少为三个，且所述的拼合式环形圈中任意一个的中心和剩余的拼合式环形圈中的任意两个且与该拼合式环形圈不位于同一直线上的拼合式环形圈的中心依次相连形成三角形结构。
在上述的打桩机的钻杆保持架中，所述的拼合式环形圈呈矩形阵列状分布设置。即这里的钻杆体也呈矩形阵列分布且均周向转动穿设在拼合式环形圈内。
在上述的打桩机的钻杆保持架中，所述的衬套体与延伸套体连为一体结构，所述的弧形内衬体的数量为两个，且所述的弧形内衬体相互对接从而形成上述的环形内衬套。
在上述的打桩机的钻杆保持架中，所述的延伸套体包括与衬套体相连的直筒体，所述的直筒体连接有锥形台体，且所述的锥形台体与直筒体相连的一端的直径大小至另一端的直径大小逐渐变小。
在上述的打桩机的钻杆保持架中，两个衬套体中至少一个上设有径向贯穿直筒体的通孔。
在上述的打桩机的钻杆保持架中，所述的直筒体的外径大小大于衬套体的外径大小。
与现有的技术相比，本打桩机的钻杆保持架的优点在于：结构简单合理，拆装方便，钻杆周向转动时稳定性好，不易出现摆动现象，提高了钻杆钻孔的效率，钻杆之间不易相互干扰。

进一步地，这里的拼合式环形圈1的数量至少为三个，且拼合式环形圈1中任意一个的中心和剩余的拼合式环形圈1中的任意两个且与该拼合式环形圈1不位于同一直线上的拼合式环形圈1的中心依次相连形成三角形结构，也就是说，这里的拼合式环形圈1呈矩形阵列状分布设置。
更进一步地，本实施例中的衬套体42与延伸套体43连为一体结构，弧形内衬体41的数量为两个，且弧形内衬体41相互对接从而形成上述的环形内衬套4，这里的延伸套体43包括与衬套体42相连的直筒体431，直筒体431连接有锥形台体432，且锥形台体432与直筒体431相连的一端的直径大小至另一端的直径大小逐渐变小，其中，这里的两个衬套体42中至少一个上设有径向贯穿直筒体431的通孔433，这里的直筒体431的外径大小大于衬套体42的外径大小。
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拼合式环形圈1、弧形体11、连接条12、安装螺栓13、可拆式结构2、安装条21、钻杆体3、环形内衬套4、弧形内衬体41、衬套体42、延伸套体43、直筒体431、锥形台体432、通孔433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。
