DRILLING RIG Russian patent published in 2015 - IPC E21B19/00 E21B7/20 

FIELD: mining.

SUBSTANCE: drill rig contains the base platform installed around the rotary table sections, and swivel located above the centre of the rotary table sections. On the base platform a spatial frame with vertical guides of the swivel is installed. In the guides the rollers of axles of balancers of telescopic mechanisms are located. The ends of balancers through pivots are connected in pairs by short axles. The upper balancers of telescopic mechanisms are connected by a long axle, on which the swivel is fixed. On the base platform the hydraulic cylinders of lifting sections of telescopic mechanisms are also located. The heads of upper sections of hydraulic cylinders are connected by an axle, on which on pivots the middle parts of the upper balancers of the bottom section of telescopic mechanisms are installed. The middles of the bottom balancers of this section on bearings of swing are installed on the axle fixed on the spatial frame. On the frame vertical guides of the drum are also located, were the drill-pipe stands are located. Above the centre of gravity of the drum the rotating separator is located. The separator is located in the chuck collet on hydrolifts, and the rollers of chuck collet tips are installed in the vertical guide frame.

EFFECT: invention provides automation of trippings and expansion of the operational and layout characteristics of the drill rig.
