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 drill rod deviation rectifying clamping device for geotechnical engineering. The device comprises a base, a deviation rectifying base is rotatably mounted on the base in thehorizontal axis direction, the base is further provided with a rotating device for driving the deviation rectifying base to rotate, a channel allowing a drill rod to pass through is formed in the deviation rectifying base in the axial direction, deviation rectifying clamping devices are mounted at two ends of the channel, drill rod guide devices are coaxially mounted on one sides of the deviationrectifying clamping devices, a locking frame is slidingly mounted at the position, between the deviation rectifying clamping devices on the two ends, of the deviation rectifying base in the axial direction, a through hole allowing the drill rod to pass through is formed in the locking frame, a drill rod clamping device is rotatably mounted in the through hole, and a sliding device for driving thelocking frame to slide is arranged at one end of the deviation rectifying base. The device has the beneficial effects that the drilling rod is convenient to dismount and mount, upper space can be effectively saved, the drilling rod is subjected to inclination angle deviation rectifying and drilling point deviation rectifying, it is effectively ensured that the drilling rod is perpendicular to theground, a drilling bit of the drilling rod 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...
