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 drilling, in particular to an SDL pile drilling method and a pile drilling machine specially used for implementing the method. Background technique [0002] In the piling industry, there are two main methods of mechanical excavation and drilling construction. The first is rotary cutting drilling, such as rotary drilling, positive circulation drilling, reverse circulation drilling, auger drilling, and reaming drilling. etc. belong to rotary cutting drilling; the second is punching drilling, immersed tube drilling, column hammer punching drilling, Ukazi percussion drilling, pneumatic down-the-hole drilling, etc. all belong to punching drilling. Among them, the punching drilling is widely used because the drill bit can impact on the corresponding formation while rotating, and the drilling efficiency is high. Cut impact drilling system", the rock drilling rig includes a base with a vertical stand, a power head is...
