摘要： PROBLEM TO BE SOLVED: To pull a steel pipe buried in the ground out of the ground simply by utilizing an internal wall of the steel pipe.
SOLUTION: A spear 1 is attached to a tip of a boring rod 2 while a slider 3 is positioned in the lowermost part and is inserted into the steel pipe 21. The boring rod 2 is rotated and a spear 1 body is rotated to lift the slider 3 for the body by action of a screw. A friction spring of a jaw 4 is pressed against the internal wall of the steel pipe 21 to prevent the jaw 4 and the slider 3 from rotating together by friction resistance. The jaw 4 is pushed out onto an outer side by lifting the slider 3 and is pressed against the internal wall of the steel pipe 21 so that teeth 40 of the jaw 4 bite into the internal wall of the steel pipe 21. The boring rod 2 is gradually pulled up, the jaw 4 bites into the internal wall of the steel pipe 21 completely, and the spear 1 and the steel pipe 21 are mutually integrated to pull up the boring rod 2 while applying vibration to the boring rod 2.

摘要： PROBLEM TO BE SOLVED: To provide a digger which improves construction efficiency by preventing clogging with gravel. SOLUTION: The digger 1 is fitted to the front end of a rod 11, and is suspended in the earth for drilling work. A fixed pipe 12 for reverse circulation is fixed to the front end of the rod 11, and hydraulic motors 2, 2, which rotates a bit 3, are disposed on both sides of the fixed pipe 12. Earth and sand dug up by the rotation of the bit 3 is sucked together with dug mud water into the front end entrance of the fixed pipe 12, and is sent out onto the ground by an underwater sand pump 4, which is driven by a hydraulic motor 40, as shown by an arrow in the drawing. The digger 1 includes a fixed teeth 51 which are spaced at proper intervals and are fixed to the inner surface of the front end of the fixed pipe 12, and crushing teeth 52 which extend from the base of the bit 3 to the inside of the fixed pipe 12 and circle along the inner periphery of the fixed pipe 12 as the bit 3 rotates. Gravel is crushed by the fixed teeth 51 and crushing teeth 52, and is sent out onto the ground smoothly. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To relax an impulsive contract surface pressure load when starting a turn table-type rotary drive transmission device.SOLUTION: The center of rotation of a turn table 1 and the center of a kelly rod 4 agree with each other, a gap between a torque transmission surface 11 of the turn table 1 and a protrusion 41 for transmission of a rotary drive force, which is brought into contact with the torque transmission surface 11 of the turn table 1 when the turn table is rotated in the direction of an arrow, is substantially eliminated, and a gap (α) is formed between the side of an opposite surface and the torque transmission surface of the turn table 1. Since the gap is substantially eliminated, an impulsive contract surface pressure load at the rotational starting of the turn table 1 is relaxed, the protrusion 41 for the transmission of the rotary drive force of the kelly rod 4 is hardly damaged, and a use period of the kelly rod can be prolonged to increase economical efficiency.
摘要翻译：要解决的问题：当启动转台式旋转驱动传动装置时，放松冲击式压缩载荷。解决方案：转台1的旋转中心和凯利杆4的中心彼此一致，转台1的转矩传递表面11之间的间隙和用于传送旋转驱动器的突起41 基本上消除了当转台沿箭头方向旋转时与转台1的转矩传递表面11接触的力，并且在相对表面的侧面之间形成间隙（α）以及转台1的转矩传递面。由于间隙基本上消除，转台1的旋转启动时的冲击收缩面压力负担缓慢，所以用于传递凯利旋转驱动力的突起41 杆4几乎不被损坏，并且可以延长使用期限，以提高经济效率。版权所有（C）2013，JPO＆INPIT
