SLR168 Rotary Drilling Rig

SLR series rotary drilling rig is mainly composed of a chassis, a driving room, walking institutions, luffing mechanism, power head, mast mechanism, winch system, drilling tool system, hydraulic system and electrical system structure. On the bus by Daewoo Doosan imported, Cummins, Germany Mann and Japan Isuzu engine are adopted according to the models. The walking mechanism through hydraulic system control achieve forward, backward, turn left, turn right. Chassis, a left and a right longitudinal beam is rig on the bottom rack, total weight bearing rig, in the bottom bracket installed four hydraulic support cylinder, by manipulating the crawler walking mechanism of stretching and retracting the. This function can make the rotary drilling rig in the operations by broadening the crawler, keep the stability of the whole machine, and in the transport of the machine state retracted, guaranteed to meet the transport requirements of the whole width. Frame supporting seat installation ---- central rotary joint, through the central rotary joints to achieve hydraulic system oil transfer to a crawler walking hydraulic motor and realize the walking function. Drill pipe system by 3-5 whole telescopic drill pipe, does not work completely contractive; drilling work according to the different depth of drilling in turn out; the drill bit is according to recover from the inside outward
