After the
roof bolter is operated, turn off the water first, and rinse the surface of the rig with water, and then run it dry for a while to achieve the purpose of water removal and rust prevention. Check whether the drilling rig is damaged, whether the bolts are loose, and deal with it in time. Place the drilling rig in a safe place vertically to avoid accidental damages such as blasting, rolling, rolling, etc. Before drilling, it is necessary to ensure the stability of the roof and the coal bank and perform safe operations. Do not place the drilling rig on the ground. Because the drilling rig is placed on the ground, once the ventilation is operated incorrectly, the air leg suddenly extends, which may cause accidents.
Roof bolter is forbidden to use gloved hands to hold the drill pipe when the bolter is drilling. When opening the eye position, the drill should be stabilized and the eye opening operation should be carried out. When drilling, increase the thrust of the atmospheric leg at an even speed to avoid accidents such as slow drilling speed, stuck drill, broken drill, and chipped blades caused by uneven thrust. When the rig falls back, do not hold your hands on the air legs to prevent injury to your hands. When the bolting rig is loaded and unloaded, there will be a reaction torque. But both can control the rocker arm to achieve balance. Especially when loading and unloading suddenly, the operator should pay more attention to the position and hold the rocker handle reasonably.
The roof bolter has small size, light weight, simple operation and convenient maintenance. Gear type air motor, stable operation and high reliability. New FRP air leg design, safe explosion-proof and longer service life.
