Drill pipe conveying device for coal mine drilling rig

Abstract

The invention discloses a drill pipe conveying device for a coal mine drilling rig and belongs to the field of machinery design. The drill pipe conveying device comprises an articulated manipulator and a drill pipe box, wherein the articulated manipulator and the drill pipe box are integrated to the same side of the lifting tilting mechanism of the drilling rig; the articulated manipulator comprises a dip angle adjusting joint, a rotation joint, a telescoping joint and a gripper joint, the dip angle adjusting joint is mounted on the lifting tilting mechanism and comprises a dip angle motor, a dip angle reducer and a rotary arm, the rotation joint is mounted on the rotary arm and comprises a rotation motor, a rotation shaft and a rotation arm, the telescoping joint is mounted on the rotation arm and comprises a telescoping device, a telescoping outer cylinder and a telescoping arm, and the gripper joint is mounted on the telescoping arm and comprises an upper fixed jaw, a lower movable jaw and a clamping device. The drill pipe conveying device is large in dip angle adjusting range, accurate in positioning, convenient to mount and maintain, high in anti-pollution capacity, small in size, and the like.

Description

technical field [0001] The invention belongs to the field of mechanical design, and in particular relates to a drill pipe conveying device for a coal mine drilling rig. Background technique [0002] The drill pipe conveying device is an auxiliary device used for coal mine drilling rigs. Its function is to deliver the drill pipes required for drilling to the drilling rig, or to retrieve the drill pipes withdrawn from the construction hole. There are following defects in the existing drilling rod conveying device: [0003] 1. The existing drill pipe conveying device is suitable for a small range of drilling inclination angle, generally 0~+45°; in fact, coal mine drilling rigs are often used for drilling at a large inclination angle above +45°, so this inclination angle range cannot meet production requirements. need. [0004] 2. The inclination adjustment and rotation angle adjustment of the existing drill pipe conveying device completely rely on mechanical limit, that is, t...
