Spesifikasi operasi keselamatan jack hammer
Rock drill（jack hammer） is a tool for directly mining stone. It drills holes in the rock in order to explode explosives away from the rock, thereby completing the mining of stone or other masonry. In addition, the rock drill can also be used as a destroyer to destroy hard layers such as concrete. Rock drills can be divided into four categories according to their power sources: pneumatic rock drills, internal combustion rock drills, electric rock drills and hydraulic rock drills. Let's give you the safe operation specifications of the rock drill.
1. Before rock drilling, check the integrity and rotation of all parts (including rock drills, supports or rock drilling rigs), add necessary lubricating oil, check whether the air and water channels are unblocked, and whether the connection joints are firm.
2. Beside the working face, knock on the wall and ask the top, that is, check the roof and the second wall close to the working face for live rocks and loose rocks, and make necessary treatment.
3. To prevent the drilling from slipping or shifting, the drilling should be leveled before drilling.
4. It is strictly forbidden to drill dry holes. Stick to wet rock drilling. When operating, the water should be boiled first, and then the air should be turned on. When stopping drilling, turn off the air first, and then turn off the water. When opening a hole, drill at low speed first, and then drill at full speed after drilling to a certain depth.
5. Personnel supporting drills are not allowed to wear gloves when drilling.
6. When using the pneumatic leg drill, pay attention to the standing posture and position, never rely on body pressure, never stand under the drill pipe in front of the rock drill, so as to avoid the drill pipe breaking and hurting people.
7. When abnormal noises or abnormal discharge of powder and water are found during rock drilling, the machine should be shut down for inspection to find out the cause and eliminate it before drilling.
8. When exiting the rock drill or replacing the drill rod, the rock drill runs slowly. Pay attention to the position of the steel drill rod of the rock drill to prevent the drill rod from falling off and hurting people, and close the gas path in time.
9. When using the air-leg rock drill, the top should be firmly supported to prevent the top from slipping and hurting people.
10. When using the telescopic support of the upward rock drill, the drill rod must be well supported to prevent the drill rod from falling automatically.
