Drill pipe axial delivery positioning detection device

Abstract

This utility model relates to a drill rod axial conveying positioning detection device, comprising: an axial conveying mechanism, which includes multiple conveying rollers evenly spaced along the drill rod conveying direction for conveying two drill rods axially; a positioning detection mechanism, which includes a base with a first bearing rotatably engaging with an outer rod, one end of the outer rod having a first stop bar and the other end having a first detection rod; the outer rod is hollow, and an inner rod rotatably engaging with it via a second bearing, with both ends of the inner rod extending beyond the outer rod, one end having a second stop bar and the other end having a second detection rod; two proximity switches are provided on the base, respectively cooperating with the first and second detection rods; and two sets of pre-tightening mechanisms are also included, used to ensure that the two detection rods are within the detection range of the corresponding proximity switches when the two drill rods are not in position, keeping the proximity switches normally closed. This utility model can simultaneously detect the axial position of two drill rods, improving detection efficiency and accuracy.
