A drill pipe positioning and guiding device for drilling based on soil layer

Abstract

The invention discloses a drilling rod positioning and guiding device for drilling holes based on soil layers, and relates to the technical field of soil layer drilling equipment. The invention comprises a base, the base includes a base plate, the base plate is equidistantly penetrated with anchor fixing columns, the upper surface of the base plate is equidistantly fixed with columns, the upper end of the column is fixed with a top plate, and one end surface of the top plate is provided with a first opening; the lower end surface of the top plate, etc. A first drive mechanism is installed, and the output shaft end of the first drive mechanism is fixed with a first threaded rod that passes through the first port and extends to the top of the top plate. The outer surface of the first threaded rod is threaded with a support structure; the support structure includes a A support column matched with threaded rods, one end of the support column is fixed with a support plate. The present invention solves the problem of directly using the drill pipe for drilling without adding a positioning guide device in the prior art through the use of the buffer support structure, support structure, guide column and rotating gear, which may easily cause the drill pipe to tilt and affect the drilling. A question of precision.

Description

technical field [0001] The invention belongs to the technical field of soil layer drilling equipment, in particular to a drilling rod positioning and guiding device for drilling based on soil layers. Background technique [0002] The drill pipe is a steel pipe with a threaded tail, which is used to connect the surface equipment of the drilling rig and the drilling and grinding equipment or the bottom hole device at the bottom of the drilling well. The purpose of the drill pipe is to transport the drilling mud to the drill bit and raise, lower or Rotary bottom hole device. Drill pipe must be able to withstand enormous internal and external pressure, twisting, bending and vibration. In geological exploration work, drilling equipment is used to drill a columnar hole with a small diameter and a large depth underground, also known as drilling. Boreholes for oil and gas and groundwater are larger in diameter. The diameter and depth of the borehole depend on the burial depth of ...

Problems solved by technology

[0004] The purpose of the present invention is to provide a drilling rod positioning and guiding device for drilling based on soil layers. Through the use of buffer support structures, support structures, guide columns and rotating gears, it solves the problem of not adding positioning and guiding when drilling in the prior art. The device directly uses the drill pipe to drill holes, which may easily cause the drill pipe to tilt and affect the drilling accuracy
