A vertical drilling guide anti-whirl drill tool assembly connecting structure

Abstract

The utility model relates to petroleum and natural gas drilling and geological exploration equipment technical field discloses a vertical drilling guide anti-vortex drill tool combination connecting structure, including guide pipe and drill bit, both are fixed through the buckle structure that is evenly distributed in the buckle groove of joint outer wall. The buckle structure contains fixed axle, push rod, rotation axis, lock catch and clasp, and the lever type quick tension and locking are realized through the push of push rod. The inside of joint still is equipped with reinforcing component, and multiple reinforcing bars that are in the form of grid cross arrangement are clamped and fixed through screw rod and nut, form high rigid skeleton. The utility model discloses the buckle type buckle structure based on lever principle is arranged at the guide pipe and drill bit connecting place, realizes the quick dismounting of drill bit, does not need heavy auxiliary equipment, and through the internal mesh reinforcing bar, the torsional rigidity and anti-vortex deformation capacity of joint are improved significantly, effectively prolongs the service life of drill tool and improves the drilling operation efficiency.
