Air leg rock drills are used in many fields, but improper operation may not only reduce the operating efficiency, but also may be dangerous. Therefore, the correct operating procedures for air leg rock drills are skills that every operator must learn and master.
The specific safety operation rules of the
air leg rock drill are as follows:
1. Check the integrity and rotation of each component (including rock drill, bracket or rock drilling trolley) before rock drilling, add necessary lubricating oil, check the air path, whether the water path is smooth, and whether the connection joints are firm.
2. Knock and help the top near the working surface of the air leg rock drill, that is, check whether there is live rock and turquoise on the roof and the second gang near the working surface, and make necessary treatment.
3. The level of the blasthole on the working surface must be leveled before drilling is allowed to prevent slippage or displacement of the blasthole.
4. It is strictly forbidden to dry eyes. Wet rock drilling must be adhered to. The water should be turned on first, then the wind should be turned on, and the wind should be turned off when the drilling is stopped. When opening the eye, run at low speed first, and then drill at full speed after drilling a certain depth.
5. The drill supporter is not allowed to wear gloves when drilling holes in the air leg rock drill.
6. When using air leg drilling, pay attention to the standing posture and position, never pressurized by the body, or stand under the power drill rod in front of the rock drill to prevent the broken drill from hurting people.
7. Abnormal sound is found in the rock drilling of the gas leg rock drill. When the powder discharge and water are abnormal, the machine should be stopped and checked to find out the cause and eliminate it before continuing to drill.
8. When exiting the rock drill or replacing the drill rod, the rock drill can run at a slow speed, pay attention to the position of the steel drill of the rock drill, avoid the automatic fall of the drill rod and hurt people, and close the gas path in time.
9. When using the air leg rock drill to drill the rock, the top should be firmly jacked to prevent the top from slipping and hurting people.
10. When using the upward-type rock drill to retract the support, the
air leg rock drill must support the drill rod to prevent the drill rod from falling automatically
