Description

Technical Field

[0001] The utility model relates to the technical field of geological exploration drilling, in particular to an anti-deviation device for geological exploration drilling. Background Technique

[0002] Geological exploration drilling is a method of obtaining underground geological information through drilling. It is one of the important means of geological survey and mineral exploration, and is also a commonly used technical method in the fields of engineering geological exploration, hydrogeological exploration and environmental geological exploration.

[0003] When the drill bit of a geological exploration drilling device drills underground, it may be affected by the external environment, resulting in the overall deviation of the drill bit. In addition to the drill bit, most of the body parts of the drill head are cylindrical. The anti-deviation structures of traditional geological exploration drilling devices usually need to replace limit clamps with different arcs according to the diameter of the cylinder, which is very inconvenient and difficult to be applicable to drill heads of various sizes for drilling work.

[0004] Therefore, the technical personnel in this field provide an anti-deviation device for geological exploration drilling to solve the problems put forward in the above background technique. Content of the Utility Model

[0005] The purpose of the utility model is to solve the defects existing in the prior art, and to propose an anti-deviation device for geological exploration drilling. First, rotate the bidirectional threaded rod. Due to the opposite thread action at both ends of the bidirectional threaded rod, the movable plates sleeved at both ends of the bidirectional threaded rod move synchronously in the opposite direction. The top ends of the two movable plates are both provided with limit plates, and triangular grooves are opened at the opposite ends of the limit plates. The design of the triangular grooves can meet the limit requirements of cylinders of different sizes, and solves the defect that traditional limit clamps are difficult to be applicable to drill heads of various sizes for drilling work.
