Technical operation of auger drilling machine safety

Technical operation of auger drilling machine safety
A rig site, should be rig specification requirements to clear the hole and the surrounding rocks and other obstacles.
Two, the job site away from the power transformer or power supply main trunk line distance should be within 200m startup voltage drop shall not exceed 10% of the rated voltage.
Third, the motor and control box should have a good grounding device.
Before installation, you should check and confirm the drill edm pipe and other components without distortion; After installation, the centerline of the drill pipe and the power head to allow deflection for 1% of the full-length.
Installation drill pipe from the power head start, section by section, down the installation. Shall not be required to drill pipe length on the ground all connected lifting time after installation.
Six, before the installation of the power head, you should remove the pulley, the rope to wear around the well. The selection of wire rope, with the requirements shall be specified.
After installation, the pointer on the frequency of the power control box frequency change-over switch should be the same, time, frequency conversion switch to be converted.
8, the rig should be placed on a smooth, solid, Auto drilling machine should be a good leg, from the tire support and apply automatic tuning or line hammer to adjust the tappet, so that it remains vertical.
Nine should be checked before the start and firmly connected to the belt tightness appropriate to confirm the various parts of the shop machine, reducer box oil level compliance, drilling depth limit alarm device.
Ten, before the start of the joystick should be placed in the neutral position. Starts, for the empty running test, inspection instruments, temperature, sound, braking and other workers often before operating.
11, Shi drill should first drill pipe slow down, so that a drill alignment holes, you can drill ammeter pointer favor of the no-load state. In the drilling process, When ammeter more than the rated current should slow down the drilling speed.
12, the rig drill-limit alarm signal is issued, you should stop drilling, and slightly enhance the drill pipe to be to disarm the alarm signal, in order to continue to the next drill.
13, drilling, drill card should be immediately cut off the power to stop drilling. The end to identify the reason shall not be forcibly start.
14 operations, when the need to change the direction of the drill pipe rotation should be drill pipe completely stall after.
15, drilling, when the rack issued by the rhythmic sound of the shake, move, skew or drill, you should immediately stop drilling may continue after treatment, Shi drill.
16, reaming meet the requirements aperture stop expanding cut close together reaming cutter tube, slightly loose a few laps, so that the tube memory soil all transported to the ground, you can stop drilling.
17, operating in the power outage, each controller should be placed off the power and timely allocated the drill pipe from the hole, so that the drill bit touches the ground.
18 rigs running, you should prevent the cable is wrapped around the drill pipe in, there must be someone care.
19., Drilling, is strictly prohibited by hand to remove the soil from the spiral film. Found that tightening the bolts loose, you should immediately shut down, tightened before continuing operation.
Twenty, into the hole, the orifice should be stamped with protection.
Twenty-one, after handling the drill pipe and drill bit should be all the upgrade to the hole to clear the mud on the drill pipe and spiral blade, and then drill press contact with the ground, the ministries braking live, joystick into the neutral position cut off the power.
XXII, when the drill bit wear volume of 20mm should be replaced.
