Mining drill rod changing manipulator

Abstract

The invention discloses a mining drill rod changing manipulator, and belongs to the technical field of mining mechanical equipment. The mining drill rod changing manipulator comprises a base, a slewing bearing, a lifting part, a translation part and a gripper assembly; the slewing bearing is arranged between the base and the lifting part; the lifting part is vertically arranged and is used for controlling the vertical lifting of the manipulator; the translation part is horizontally arranged and used for controlling the horizontal movement of the manipulator, and one end of the translation part is fixedly connected with the top end of the lifting part through a flange; the gripper assembly is vertically arranged and comprises a gripper opening and closing oil cylinder, a fixing frame, a four-bar mechanism, a left holding claw and a right holding claw; the fixing frame is arranged on the gripper opening and closing oil cylinder; the top end of the gripper opening and closing oil cylinder is in transmission connection with the translation part through a swing oil cylinder, and the bottom end of the gripper opening and closing oil cylinder is fixedly connected with the top end of the four-bar mechanism; the bottom end of the four-bar mechanism controls the left holding claw and the right holding claw correspondingly; and the top end of the left holding claw and the top end of the right holding claw are both hinged to the fixing frame. The problem that when drill rods are spliced and disassembled, operation of workers is difficult can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of mining machinery and equipment, and particularly relates to a mining drill changing manipulator. Background technique [0002] With the increase of mining depth and strength of coal mines, rock bursts are more and more frequent, and the losses caused by them are also increasing. At present, one of the main measures to prevent rock bursts in coal mines is to drill holes in the coal seam to release the coal seam pressure. Use a pressure relief drill for pressure relief work. Most of the currently known pressure relief drilling rigs use an auger rod to drill holes in rock formations. [0003] However, due to the large depth of drilling and the number of drill rods required, it is necessary to connect multiple drill rods end to end to drive into the coal wall; after a drilling is completed, the drill rods must be pulled section by section. In and out of the drill pipe box. Due to the limited space for un...
