Description

TECHNICAL FIELD

[0001] The utility model relates to the field of geotechnical engineering investigation, and particularly relates to a wheel disc type shallow thread drill righting device. BACKGROUND

[0002] The shallow thread drill can find out the thickness of the fill layer, the depth of the hidden ditch and the buried depth of the shallow soil bearing stratum, and is widely used in geotechnical engineering investigation of natural foundation and poor geological conditions. The conventional drilling method of the shallow thread drill is as follows: two pipe wrenches are used to clamp the two sides of the thread drill rod in parallel, and manual pressing and hand shaking drilling are adopted. This drilling method usually requires three people to operate together, one person righting the thread drill rod, and two people pressing the pipe wrenches for manual shaking drilling. It is difficult to automatically right, and has become a big problem in the process of geotechnical engineering investigation.

[0003] The conventional dismounting method of the drill rod of the shallow thread drill is as follows: one pipe wrench is used to clamp one drill rod, and the other pipe wrench is used to clamp one drill rod. The pipe wrenches are pulled in opposite directions to realize dismounting. This method requires two people to cooperate, and the sliding rod is easy to cause personal injury during the dismounting process. Not only is the manpower wasted, but also it is not very safe.
