The main function of the drilling rig is to drive the drilling tool to break the rock at the bottom of the hole, and to lower or lift the drilling tool in the hole.Friction welding drill pipe. It can be used to drill cores, ore cores, cuttings, gaseous samples, liquid samples, etc. to explore underground geology and mineral resources.

Friction welding drill pipeandTechnical rules for the safe operation of drilling rigs:

When working, pay attention to whether the tension of the tie rod is normal, and do not work when the tie rod is loose to prevent damage to the mast.

Do not use a slipping friction clutch to prevent friction plate wear.

After braking the reel, loosen it intermittently and drop the drill bit into the borehole without making it fall freely. Frequently check the damage of wire rope, such as broken wire exceeding5%, should be replaced in a timely manner. Tungsten gold sleeve shall be subjected to tensile test. The number of clamps connecting the wire rope and the drill bit shall be installed according to the same strength.

When working with two pulleys in the wire rope pulley group, in order to make the mast load uniform, the pulleys on both sides should be loaded, and the middle pulley can move freely.

In order to check the thread connection at the joint after screwing on the drilling tool, a chisel must be used as a check mark line.

Friction welding drill pipeBefore lowering to the bottom of the well, check that the bit is installed correctly and the drilling tool should be free of cracks.

In order to avoid premature wear and damage of the machine, do not use the weight larger than the instructions in the work.drill pipe.

In order to prevent the drilling tool from being caught, it must not be left at the bottom of the well when not working.

During the lowering operation, if the drilling tool is stopped, it should not be suspended in the air, but should be raised and then lowered again.
