Preparation and commissioning before horizontal directional drilling

① The base of the directional drilling rig is fastened on the machine platform with anchor bolts. The base and all components must be installed smoothly and aligned.
② It must be ensured that the center of the vertical shaft (or turntable), the rim of the crown wheel and the center of the hole are in a straight line.

③The assembly sequence of XU300-2 vertical shaft hydraulic drilling rig: mobile hydraulic cylinder—frame—base—hydraulic control valve, fuel tank, transmission gearbox—clutch and hydraulic pump transmission—hoist—diesel engine, brake, hoist guard— Gyrator—beam chuck.

④ When installing the pressurizer, it is necessary to align the double planetary gears with marked tooth grooves (that is, the tooth grooves where the geometric centers of the two gears coincide) with the center sleeve shaft gear at the same time.

⑤ When installing the lower shaft of the gearbox, pay attention to install the two positioning steel balls and the interlocking cylinder. When disassembling, the handle must first be hit to the neutral position, and then the upper and lower shafts are removed.

⑥Fix the hoisting wire rope head on the elevator drum. The wire rope is wound left-handed on the rope drum, and the other end of the wire rope passes through the crown block and the traveling block and is fixed on the bottom beam of the drilling rig or on the traveling block for lifting and lowering the drilling tool.

⑦ When closing the gyrator of the vertical shaft drilling rig, pay attention to the tightness of the meshing of the bevel gears, otherwise the gasket must be replaced.

⑧In combination with the specific drilling rig, follow the relevant items in the drilling rig manual for installation.
