YGSL-120 Anchoring Drilling Rig

1.Summary YGSL-120 Track-type Anchoring Drilling Rig is a dual- top drive power head drilling machine of tract chassis with full hydraulic drive .It extends the applied rang of construction.The rig is applied to the big tonnage stress anchoring hole for water power station,railway,highway, the high-pressure jet grouting hole in the gravel land and to the demolishing hole of construction.It is also used to drill small size water well and foundation pile holes ,as well as drainage well. 2.Features 2.1The machine is easy to move and to align. 2.2The machine chassis is of steel track, which has small pressure on earth and big-withstanding capacity. 2.3Dual-top drive power head realizes various drilling method, such as: a)When drilling hole in thicker (3050 m) fractured zone or congeries, rear power head connected with inner drilling tool and DTH hammer, for realize percussion rotary drilling, in the meanwhile, front power head rotates the follow-up casing for protecting hole wall. b)When drilling hole in incoherent overlying formation, quicksand layer or silt layer, the inner drilling tool use conventionality rotary tools or long auger drilling tools, in the meanwhile, front power head rotates the follow-up casing for protecting hole wall. c)When drilling hole in intact formation, only one power head is used for ordinary rotary drilling or percussion-rotary drilling. 2)It features high lift capacity and output torque, strong disposing accident ability and high drilling efficiency. 3)Rig carry out mechanization of rod and casing breaking down, as it equipped the clamp and breakout machine, so it can hugely reduce labor strength and increase work efficiency. 3.main Technical Specification 3.1 Drilling Hole Diameter (mm) φ130 250 3.2 Drilling Hole Depth (m) 150 3.3 Recommend dring rod (diameter×length) 89×2000 mm 114×2000 mm Recommend casing size (diameter×length) 168×2000 mm 178×2000 mm 194×2000 mm 3.4 MAST Drilling mast vertical rotory angle (degree) 0 120 Drilling mast lateral rotory left angle (degree) 20 Drilling mast lateral rotory right angle (degree) 90 Main drilling arm rotory vertical angle (degree) -20 +35 Main drilling arm rotory lateral angle (degree) -30 +90 Drilling mast moving distance (mm) 1100 Compensatory stroke of front head(mm) 400 3.5 Rotary speed of top drive power head Rear head (r/min) 3180 Front head (r/min) 322 3.6 Max.
