The invention discloses a
drill rod automatic stacking and conveying device, which is mainly composed of a ramp part, a specific crane and a clamping arm and clamping jaw mechanism, wherein a slideway and a trolley are arranged below a suspension arm of the automotive crane; the trolley is provided with the clamping arm and clamping jaw mechanism which can be used for directly grabbing
drill rods; a catwalk body provided with a groove is directly fixed on an inclined plane of the ramp; arranged
pipe blocks (namely groove entering mechanisms) are arranged at two sides of the catwalk body; when the
drill rods are conveyed to a
drill floor, one drill rod is suspended to be placed on the arranged
pipe blocks on the ramp by the crane, the drill rod rolls into the groove through the arranged
pipe blocks, and is pushed to the
drill floor through a
pulley; when the drill rod is put down by the
drill floor, the process is opposite to the above process; the drill rod which glides into the groove and is jacked and pushed onto the arranged tube blocks is automatically suspended onto the ground to be put in order by the crane; the catwalk body is in a fixed type and in a rotary type; the upper end of the rotary-type catwalk body is connected with the upper end of the ramp through a hinge; the lower side of the rotary-type catwalk body can be rotated upwards around a hinge under
hydraulic control, and the rear end of the rotary-type catwalk body is lifted up. With the adoption of the drill rod automatic stacking and conveying device, a catwalk
machine is leaved out, the arranging and conveying complete
automation of the underground drill rods is realized, so that unmanned operation is realized.
