Drill rod centering adjuster

Abstract

The invention discloses a drill rod centering adjuster. The drill rod centering adjuster comprises a first adjuster fixed plate, a second adjuster fixed plate, a lead screw, a guide rod, a left V-shaped opening assembly, a right V-shaped opening assembly, a coupling and a hydraulic motor, wherein a guide rod and a lead screw are arranged in parallel between the first adjuster fixed plate and the second adjuster fixed plate, the two ends of the guide rod are fixed on a guide rod seats of the first adjuster fixed plate and the second adjuster fixed seat, the two ends of the lead screw are mounted on the rolling bearings of the first adjuster fixed plate and the second adjuster fixed plate, one end of the left V-shaped opening assembly sleeves the guide rod, while the other end of the left V-shaped opening assembly is in threaded connection with the lead screw, one end of the right V-shaped opening assembly sleeves the guide rod, while the other end of the right V-shaped opening assembly is in threaded connection with the lead screw, the V-shaped openings of the left V-shaped opening assembly and the right V-shaped opening assembly are opposite to each other, and one end of the coupling is connected with the lead screw, while the other end of the coupling is connected with the rotating shaft of a hydraulic motor. The drill rod centering adjuster is small in appearance, and simple and reliable in structure; the diameter range of drill rods which can be centered and adjusted by the drill rod centering adjuster is large, and the drill rod centering adjuster is controlled hydraulically; besides, the drill rod centering adjuster is easy to process and manufacture.

Description

technical field [0001] The invention relates to a drill pipe centering adjustment device, in particular to a drill pipe centering adjuster, which can be used for fully hydraulic transmission drilling rigs with drill pipe connection and unloading functions, and is especially suitable for fully automatic remote control connection and unloading of drill pipes working on the seabed The utility model relates to a deep hole core sampling drilling machine, which belongs to the technical field of mechanical engineering. Background technique [0002] Many drilling rigs used in modern mine rock drilling and geological exploration have the function of automatically loading and unloading drill pipes, so hydraulic or mechanical rotary power chucks and drill pipe holders are used to clamp and connect the upper and lower drill pipes. Unscrew the buckle. Before the rotary power chuck and the drill pipe holder respectively clamp the upper and lower drill pipes and unscrew the connecting thr...

AI Technical Summary

Problems solved by technology

If the upper and lower drill pipes are not centered and adjusted before the upper and lower drill pipes are unscrewed, then during the unscrewing and unscrewing of the upper and lower drill pipe connection threads, the upper and lower drill pipe connection wires The friction and wear between the buckles will become very serious, which will make it very difficult or even fail to unscrew the connecting threads of the upper and lower drill pipes, and will reduce the service life of the drill pipes
