METHOD AND DEVICES FOR MANIPULATION OF PARTS SUCH AS BARS DURING DRILLING AND ANCHORAGE Russian patent published in 2012 - IPC E21B19/14 E21B19/20 E21D20/00 E21B7/02 

FIELD: mining.

SUBSTANCE: extended bars, such as boring bars and anchor bolts, are stocked into a linear accumulating device for rods, equipped with supplying elements for rods displacement up and down in the accumulating device. Feeding elements comprise helical surfaces, by means of which bars are supported in the accumulating device. The required feeding motion is developed by means of feeding elements rotation around their axis of rotation. The accumulating device for bars additionally comprises a displacement facility, which provides for the possibility of bars displacement from the accumulating device into a boring line or a bolt jointing line, i.e. to the centre and back. The displacement device is additionally equipped with a gripping device for bars gripping.

EFFECT: simplicity, reliability, ease of control and transfer to automatic mode, small dimensions and weight of equipment.
