Description

打桩机钻杆组件 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钻杆组件。
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，在钻杆钻孔的同时采用灌浆来对钻杆进行降温以及对钻杆进行灌浆作业，常见的灌浆主要通过钻杆端部的灌浆孔进行喷浆，但是现有的钻杆在进行喷浆过程中易发生堵塞现象，且存在喷浆面积小，喷浆效果差的问题，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灌注桩螺旋提升浆泥钻杆[申请号：201410263015.7]，其包括一段或若干段空心钻杆以及与其相连的钻杆接头，空心钻杆的外表面上设置有螺旋叶片，每段空心钻杆每段空心钻杆间以钻杆接头连接，第一节空心钻杆与钻头的连接处设置喷浆口。通常，该螺旋叶片焊接于空心钻孔上，且设置在空心钻杆的下段，螺旋叶片的长度为空心钻杆的总长度的1/4-1/2，其直径小于钻头的直径。在施工中螺旋叶片随钻杆正方向旋转，对桩孔下段的泥浆及泥浆中的 泥块等产生向上的提升力，同时对钻杆产生向下的推进力。
上述方案在一定程度上解决了现有打桩机钻杆灌浆效果差的问题，但是该方案依然存在着：易发生堵塞现象，存在喷浆面积小的问题。
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，喷浆面积大的打桩机钻杆组件。
为达到上述目的，本发明采用了下列技术方案：本打桩机钻杆组件，包括中空的钻杆体，其特征在于，所述的钻杆体一端具有钻头尖锥部，在钻杆体设有钻头尖锥部的一端周向外侧设有呈螺旋状分布设置的螺旋钻头叶片，所述的螺旋钻头叶片一端延伸至钻头尖锥部，另一端与径向设置在钻杆体外侧的喷浆座相连，所述的喷浆座朝向钻头尖锥部的一侧具有至少一个与钻杆体内部相连的喷浆孔，且所述的喷浆孔的孔径由内向外逐渐变大。即这里的喷浆孔的直径由内向外逐渐变大，这样能使的喷出的浆液呈扇形分布，随着钻杆体周向转动使得浆液快速到达钻孔各处。
在上述的打桩机钻杆组件中，所述的喷浆座内设有沿喷浆座轴向延伸的连接通道，且所述的连接通道一端与钻杆体内部相连通，另一端与喷浆孔相连。
在上述的打桩机钻杆组件中，所述的螺旋钻头叶片与喷浆座设有喷浆孔的一侧齐平且相连，且所述的喷浆座的另一侧具有超出螺旋钻头叶片且位于螺旋钻头叶片端部的阻挡部，所述的阻挡部连接有倾斜向上设置的倾斜部，且所述的倾斜部连接有设置在喷浆座远离螺旋钻头叶片一侧的弧形部。该结构不仅提高了钻孔的效率，同时也使得浆液搅拌效果更好。
在上述的打桩机钻杆组件中，所述的喷浆孔呈长条形，且所 述的喷浆孔包括与连接通道相连的等径条形孔，所述的等径条形孔连接有变径条形孔，且所述的变径条形孔与等径条形孔相连的一端的直径大小至另一端的直径大小逐渐变大。这样使得钻杆体周向转动时，喷浆孔不易堵塞。
在上述的打桩机钻杆组件中，所述的螺旋钻头叶片与钻头尖锥部相连一端的宽度直径另一端的宽度逐渐变大。
在上述的打桩机钻杆组件中，所述的螺旋钻头叶片与喷浆座均一体成型于钻杆体上。
在上述的打桩机钻杆组件中，所述的钻杆体具有钻头尖锥部的一端设有若干位于螺旋钻头叶片上方的搅拌叶片组，且所述的搅拌叶片组自上向下依次错位设置。
在上述的打桩机钻杆组件中，每一组搅拌叶片组均包括分别设置在钻杆体两侧均均与钻杆体垂直设置的搅拌叶片，所述的搅拌叶片分别朝向不同方向倾斜设置。
在上述的打桩机钻杆组件中，所述的钻杆体上分别套设有若干拼合式环形圈，所述的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。
在上述的打桩机钻杆组件中，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，且相邻两个钻杆体上的拼合式环形圈位于同一水平面上，且相邻两个钻杆体上的拼合式环形圈的连接条外侧分别设有安装条，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。即相邻两个钻杆体上的拼合式环形圈相连，这样提高了钻杆体周向转动时的稳定性，钻杆体不易出现摆动现象，钻杆之间不易相互干扰。
与现有的技术相比，本打桩机钻杆组件的优点在于：结构简单合理，喷浆过程中不易发生堵塞现象，且存在喷浆面积大，能使浆液呈扇形喷出，喷浆效果好，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。
