摘要
  本设计涉及了长螺旋打桩机钻杆，其主要特征为，包括带有通孔的杆体。在所述杆体的外壁面带有螺旋线。当钻入地下时，工作人员根据杆体外壁面的螺旋线直接测量到钻头的转动情况和竖直行进情况。随时调整竖直行进速度和转动速度，以达到转动和竖直行进速度的同步。确保所打桩体呈螺旋状;打桩机钻头当需要更换或维修钻尖和钻镐时，不需要使用电气焊将钻尖或钻镐从钻头基体上切割下，只需要松开固定钻尖和钻镐的连接螺栓，可以方便的将钻尖和钻镐从钻头基体上拆卸下来，进行更换或维修，更换和维修钻尖、钻镐的时间很短，大大提高了作业率;打桩机立柱，其特征是，立柱为上段立柱和下段立柱分体结构，上段立柱和下段立柱通过连接装置连接为一体。在转场运输时，只需将上段立柱以销轴为支点弯拆下来，即达到公路运输不超高的要求，不需要将立柱整体拆卸省时省力。提高了工作效率;改进的滑轮组，通过增加导向轮，采用摆动式滑轮，降低了钢丝绳和滑轮的磨损。延长了使用寿命，提高了经济效益。

Abstract
  The design involves a long spiral drill hammers and its main features are: including the rod with a hole in the wall above the outer rod with a spiral line. When the burrow into the ground, the staff in vitro under the bar direct measurement of the wall of the spiral rotation of the drill bit and vertical road conditions at any time to adjust the vertical speed and rotational speed of the road, the road to reach the speed of rotation and vertical synchronization, to ensure The lanes are helical piling，hammer drill bits need to be replaced or repaired when the drill tip and the drill-ho, you do not use Dianqi Han-ho, the drill tip or drill bit from cutting the substrate, just loosen the drill tip and the drill-ho of the connecting bolts, can easily the drill tip and the drill bit matrix-ho from disassembled, replace or repair, replacement and maintenance of drill point, drill-ho for a short time, greatly improving the operating ratepile-column, and its features are: the column for the upper column and lower column sub-structure, the upper column and lower column by connecting the device is connected as one. Transport in the transition, only the upper column to remove the pin as a fulcrum to bend, that road transport does not meet the requirements of ultra-high, no need to remove the whole column saves time and effort, impr
ove work efficiency，pulley improved by increasing the guide wheel, with swing pulleys, wire rope and pulleys reduce wear and prolong the service life and improve economic efficiency.
