Modern crawler drilling rig 's main structures include: crawler chassis, the car, mast, Vice bodies, power head, telescopic drill pipe, hydraulic systems, hydraulic systems and other components.
(1) the tracked chassis: bogies, for track tensioning device, left and right longitudinal beam.
(2) car: chassis, turret, cab,, main and auxiliary hoist and the weight of the engine components.
(3) the mast: consists of cathead, pulleys, mast, pressurized fuel tank and other parts. It is the drilling of slewing mechanism, pressurizing feeding mechanism, elevator and other rig the primary executive body of important support and stress components, and installation and drill pipe drill of the drill pipe, power-oriented component.
(4) luffing: changed from a movable arm, tripod and Rod, cylinder, mast, mast oil tanks and so on. Through the cylinder, you can easily adjust the power head position and orientation of the axis, you can also adjust the mast mast or transport or transport mast height and angle of the mast relative ground.
(5) the hydraulic system: hydraulic drilling rig of hydraulic system with pilot control for main and auxiliary double loop control, mainly from the mainstream of high pressure and large flow hydraulic system circuit, auxiliary hydraulic system pressure flow in circuit, low the guide system circuit, cooling systems and dynamic head lubrication system components.
