Problems solved by technology

The existing drill pipe correction device only inserts the drill pipe into the limit ring or the guide sleeve, and corrects the drill pipe through the limit ring or the guide sleeve, but when the drill pipe is loaded into the limit ring or the guide sleeve In the interior, due to manual installation factors, there will still be a slight deviation between the drill pipe and the ground or the drill bit of the drill pipe will not be strictly aligned with the drilling point
At the same time, the traditional drill pipe correction device uses the drill pipe to be installed from the top, which requires the drill pipe to be raised to a certain height in advance, which is not only inconvenient to operate, but also takes up a lot of space above
Therefore, aiming at the defects of inconvenient installation of the drill pipe, taking up a lot of upper space, and inability to effectively adjust the inclination angle of the drill pipe and the position of the drilling point after the installation of the drill pipe, the present invention discloses a Drill pipe deflection correction and clamping device for soil engineering

Abstract

The invention discloses a drilling rod deviation correcting and clamping device for geotechnical engineering, which comprises a base, on which a deviation correcting base is installed to rotate along the direction of a horizontal axis, and a rotating device for driving the deviation correcting base to rotate is also arranged on the base. device; the deviation correction base is axially provided with a passage for the drill pipe to pass through, and the two ends of the passage are respectively provided with a deviation correction clamping device, and one side of the deviation correction clamping device is coaxially provided with a drill pipe guiding device; On the deviation correction base, a locking frame is slid between the deviation correction clamping devices located at both ends in the axial direction. The locking frame is provided with a through hole for the drill pipe to pass through. Drill pipe clamping device, one end of the deviation correction base is also provided with a sliding device that drives the locking frame to slide; the invention has the advantages of convenient disassembly and assembly of the drill pipe, effective saving of upper space, correction of the inclination angle and drilling point of the drill pipe, Effectively ensure that the drill pipe is vertical to the ground, the drill bit of the drill pipe is aligned with the drilling point, and the drilling process is stable.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering, and in particular relates to a drill pipe deflection correcting and clamping device for geotechnical engineering. Background technique [0002] The drill pipe is one of the necessary components for drilling in geotechnical engineering. When the drill pipe is used to drill holes on the ground, the position of the drill pipe will move when the drill pipe is manually hoisted and installed. The axis of the rod may not be perpendicular to the ground, and the projection of the drill bit of the drill pipe on the ground is not aligned with the drilling point, which requires a special correction device to adjust the inclination angle of the drill pipe and the position of the drilling point. The existing drill pipe correction device only inserts the drill pipe into the limit ring or the guide sleeve, and corrects the drill pipe through the limit ring or the guide sleeve, but when the drill...
