Problems solved by technology

The existing problem of this rock drilling machine is that the downward drilling force of the drill bit is provided by the self-weight of the power head, the working drill rod and the drill bit, and the maximum drilling force of the drill bit is limited. If the driving force is not enough to overcome the resistance, it will cause the drill bit to idle and not continue to drill down, which will affect the working efficiency

Abstract

The invention relates to an SDL pile work drilling method and a pile work drilling machine specially used for implementing the same. The pile work drilling machine comprises a machine frame. A power head capable of moving vertically in a guided mode is assembled on the machine frame, the power head is in transmission connection with a working drill rod, and a drill bit used for bearing vibration impact of a corresponding impactor to impact drilling is installed at the lower end of the working drill rod. The pile work drilling machine further comprises a flexible transmission piece with the axis extending along the vertical direction and a transmission piece driving device used for driving the flexible transmission piece to move vertically in a reciprocating mode. The transmission piece driving device is arranged on the machine frame, and a force transmission device used for applying downward elastic action force on the power head when the flexible transmission piece moves downwards is arranged on the flexible transmission piece. The pile work drilling machine capable of increasing drilling force of the drill bit in the punching drilling process at any time is provided.

Description

Technical field [0001] The invention relates to the field of pile workers' tunneling, in particular to an SDL pile worker's tunneling method and a pile worker's drilling rig dedicated to implementing the method. Background technique [0002] In the pile industry, there are two main methods of mechanical tunneling and drilling. The first is rotary cutting drilling, such as rotary drilling, positive circulation drilling, reverse circulation drilling, auger drilling, and reaming drilling. And so on belong to the rotary cutting drilling; the second is punching drilling, immersed pipe drilling, column hammer punching drilling, Ukatz impact drilling, pneumatic down-the-hole drilling, etc. all belong to punching drilling. Among them, punching drilling is widely used because the drill bit can impact the corresponding formation while rotating, and the drilling efficiency is high. The existing punching drilling rigs such as "a rock drilling rig and its rotary drilling rig disclosed in Chin...
