Note the use of rotary drilling rig 1, after starting the engine, should low speed for 3-5 minutes and turn the power head under load, in order to facilitate the hydraulic system is working properly. 2, the rig during operation, the operator should regularly observe a variety of instrument instruction is normal, if unusual circumstances should be stopped and checked. 3, the operation should pay special attention to the operation control lever should be in place truck mounted rig quote, in order to avoid pressure shocks to the system. 4, in the course of the tightening pressure should be checked vibration fittings and pump tightening bolts to ensure that no oil spills, leakage phenomenon. 5, the rig must be commanded by a person when walking, with particular attention to the dangerous location power lines, puddles, etc. 6, within the scope of the rig swivel strictly prohibited. 7, the rig after the transfer process, must stretch crawler flatbed immediately after the next car. 8, check the hydraulic oil, hydraulic oil cooling must wait before proceeding. 9, when the drill pipe welding parts, must turn off the power switch. 10, regularly check the swivel joint DTH drill bit end surface design in the form of DTH is an important component of submersible drilling rig truck mounted rig, face design in the form of high pressure DTH drill bit used, there are four: the end face of the convex type, end flat type, face concave and the end of central furrow. 1, the end face of the convex type: This drill two forms, single and double boss bosses face, which is mainly used for large diameter DTH Bits. Convex end surface drill DTH drilling in hard and hard to maintain when high abrasive rock drilling rig rates Car Which is good, but the flatness of drilling is poor, does not apply to blasthole flatness demanding drilling projects. 2, the end face of the flat-type: This form relatively rugged drill for drilling hard and very hard rock, but also for the flatness of drilling blast holes in less demanding hard rock and soft rock. 3, face concave: this shape drill head has a conical end face of the concave portion is formed in the drilling process, the drill slightly to keep the drill bit nucleation of performance, blast hole drilling has a good straight line degree, this drill row powder effect, drilling speed, is currently on the market use more DTH Bits. 4, the end face of the center furrow: This drill shape is evolved from the same type of ball tooth bit to the end face of the central portion of the drill bit has a deep concave central portion. For drilling during nucleation, ensure flatness when drilling deep boreholes, only applies to drilling in soft rock and hard rock.
