Drill rod grabbing component, drill rod loading and unloading arm, and loading and unloading machine for coal mine

Abstract

The invention discloses a drill rod grabbing component, a drill rod loading and unloading arm, and a loading and unloading machine for coal mine. The drill rod grabbing component comprises a magneticgrabbing piece which is arranged in the axial direction, and a mechanical grabbing piece which is arranged to cover the magnetic grabbing piece; the magnetic grabbing piece performs magnetic positioning of the drill rod; and the mechanical grabbing piece performs grabbing and fixing of the drill rod. The drill rod loading and unloading arm comprises a base and an arm body; the arm body rotates horizontally by taking the base as a centre; the arm body is at least provided with three hinged movable nodes; and a grabbing component is arranged at the end part of the arm body. The loading and unloading machine for the coal mine comprises a crawler belt vehicle body assembly; a drill rod loading and unloading assembly is arranged on the crawler belt vehicle body assembly; and the drill rod loading and unloading assembly comprises a drill rod storage box and a drill rod loading and unloading arm. The loading and unloading machine for the coal mine can be adapted to drilling construction of various occasions and working conditions; the labour intensity and the danger coefficient of workers are greatly reduced; the drill rod loading and unloading efficiency is improved; and important equipment is provided for unmanned operation and intelligent of underground drilling construction of the coal mine.

Description

technical field [0001] The invention belongs to the field of automatic drilling equipment in underground coal mines, and relates to a drill pipe grabbing member, a drill pipe loading and unloading arm and a coal mine drill pipe loading and unloading machine. Background technique [0002] With the further deepening of underground mining in coal mines, the problem of underground safety has become increasingly prominent. The development of automated and intelligent drilling rigs for various drilling constructions such as water exploration and drainage holes, gas drainage holes, and outburst prevention and pressure relief holes is imminent. The automatic loading and unloading of the drill pipe is the key technology for the development of the automation and intelligence of the drilling rig. The loading and unloading of the drill pipe of the traditional drilling rig mainly relies on the manual loading and unloading of the drill pipe from the ground to the through hole of the main s...
