Always pay attention to check the gas and water pipeline, all parts of the bolt, nut joint connection is firm and reliable. Pay attention to check the lubrication of the wind motor at any time. When there is water in the working face, a large diameter drill bit should be used for the opening, and then the drill pipe should be inserted to expose the drill pipe to the ground.100-200mm to prevent rock slag mud from falling into the hole.Outer flat drill pipeand ordinary drill pipeReverse rotation is not allowed during drilling to prevent the drill rod from falling into the hole.

When the machine stops working in a short time, a small amount of compressed air should be given to prevent sediment from invading the inside of the impactor. If the machine stops working for a long time, the impactor should be raised from the bottom of the hole.1-2 meters and then fixed.

When working, pay attention to the sound of the impactor and whether the operation of the gearbox is normal. If any abnormal phenomenon is found, stop the machine immediately for inspection. When new drill pipes are connected, special attention shall be paid to the inside of the hole to avoid sand mixing into the inside of the impactor, damaging the machine parts or causing drilling stop accidents.

At the end of each shift, the surface of the machine must be cleaned of dirt. It is strictly forbidden to disassemble and unload on the working surface (except for the case of disassembled components for easy handling) to avoid losing parts and damaging key parts of parts. Drill pipe joints are lubricated with butter. The reducer shall be lubricated with butter.

Broken drill pipe:

Most of the reason is that the drill pipe and the hole wall friction, so that the drill pipe wall thickness thinning, strength weakened. In addition, the drill pipe has been bent and is easy to break.

Preventive treatment: pay attention to check when adding drill pipes, and select drill pipes that are too worn and bent, and stop using them.
