SELF-PROPELLED ANCHORING RIG Russian patent published in 2022 - IPC E21D20/00 E21D21/00 E21B7/04 

FIELD: mining.

SUBSTANCE: invention relates to mining, in particular to installations for the construction of roof bolting, and can be used in underground mine workings for mechanized construction of screw roof bolting. The installation includes a drilling rig, a swept-type manipulator, a running gear, a diesel-electric drive, electrical equipment, a hydraulic system, and a pneumatic system. At the free end of the arm of the manipulator, swing and tilt mechanisms of the drilling rig are connected into a single unit and are driven by two pairs of rack and pinion hydraulic cylinders. The drilling rig includes a frame with two pairs of guides, along which, using a chain feed, a carriage with a drill rod rotator and a hydraulic motor and a carriage with a screw anchor rotator with a hydraulic motor move alternately, a machine rotation mechanism and a revolving device for accommodating at least 6 screw anchors, including a drum with spindles and a mechanism connected to it for automatic rotation of the drum at the end of the reverse travel of the carriage with an anchor rotator, providing alternate alignment of the spindles coaxially with the specified rotator. The drum turning mechanism is made in the form of an angular gearbox with a bevel gear and an output shaft position lock, on the drive shaft of which a freewheel bearing is installed, on the outer ring of which a spring-loaded lever is fixed with the possibility of force interaction with the anchor carriage. The revolving drum contains a steady rest, including a bar and grips of screw anchors, installed coaxially with the spindles, each of which is fixed on a separate mechanism for their deviation from the anchor erection axis when moving up the carriage with an anchor rotator.

EFFECT: invention improves the reliability and productivity of the installation for the construction of roof bolting.
