Роторная буровая установка DBR200C

DBR series Rotary Drilling Rig is a deep foundation piles of large diameter hole equipment, combines modern hydraulic pile Machinery of new technologies, new processes, the main performance has reach to an advanced level of similar products, international selection of key parts and procurement ensuring the reliability of the machine, the drill rig can be equipped with a short auger, rotary hopper, core drilling, hydraulic hammer and other drills can be boring clay layer and sandy gravel, cobble layer and the weathered strata. The Rotary Drilling Rig are widely used on the roads, large bridges, piers, high-rise building, water conservancy and other infrastructure construction projects. TECHNICAL PARAMETERS: TYPE DBR200C Chassis type BONNYZJ16A-7 194KW Max. drilling dia 1800mm Max. drilling depth 60m Max. output torque 200KN.m Drilling speed 7-28rpm Max. push 150kN Max. pull 200 kN Stroke of crowd cylinder 4300 mm Mast sideward 3° Mast forward 3° Main winch pull(1st layer) 200 kN Main winch rope dia 28 mm Main winch line speed 75m/min Auxiliary winch pull 76 kN Auxiliary winch rope dia 20mm Auxiliary winch line speed 79 m/min Operating height 20091mm Operating width 4400mm Transporting length 14085mm Transporting height 3400mm Transporting width 3000 Track plate length 5538mm Track plate width 700mm System pressure 343bar Pilot pressure 40bar Traction force 360kN Total weight 60t BASE MACHINE: Stable and serviceable traveling mechanism Stable hydraulic drive The centre revolving joint of hydraulic system transfers pressure oil of upper-structure to the crawler mechanism to realize various operation. ENGINE SYSTEM: The engine adopts the world famous engine, with high power output with low oil consumption, low discharge and low noise All-directionally Adjustable Suspended Seat with Dual-slide-rail Structure The height, location and angle of the seat are easily adjustable. The rigidity of the seat is also flexible in accordance with the weight of the operator. Suspended equipment under the chair reduces machine's vibration to guarantee operation comfortable. EASY OPERATION: The buttons and pedals are within the operator's reach. The adjustable control panel may meet operator's need of the different build; the advanced screen may display the drilling condition. MONITOR SYSTEM: Each meter of monitor system is within operator's reach, displaying fuel level, coolant, hydraulic oil temperature, machine speed, engine rotation speed; and by analysis of control system, the failure can be automatic diagnosed. HYDRAULIC SYSTEM: Imported hydraulic parts ensure the high reliability of the system. Based on it, constant power and electricity power override control make the best use of the engine power. The rig adopts pilot control system. Reliable pilot logic valve controls all actions of the rig. Pilot control is flexible, safe, comfortable and precise, which greatly improves the operational performance, flexibility, safety and comfort, and fully shows the integration of man-mechanics-electronics-hydraulics. CLOSE-LOOP CONTROL: The power of engine and pump achieves the most superior match by their closed-loop control; Through closed-loop control of rotary drive rotation speed and motor flow, rotation speed modulation come true with stepless speed-adjust to ensure great match for torque and pressure force; effectively reduce tooth wearing, protect Kelly bar and realize automatic push by pressure force closed-loop control. FAULT INTELLIGENT DIAGNOSIS: The technical parameters of engine, hydraulic system and control system are cycled checked to judge whether the rig works normally or not. When a fault occurs, the rig will be shut down timely and the fault code will be displayed to avoid more severe damage. MAST AUTOMATIC ERECTION/LYING AND VERTICAL ADJUSTMENT: Erecting, lay or adjust mast automatically according to the feedback of the mast angle CUSTOMER-MADE WIRE: Through custom-made wire, all exposed wires are replaced by cable to reduce signal disturbance and some failures; all water proof plug-in unites enhance electrical system's reliability.
