Matters needing attention in the maintenance and maintenance of
air leg rock drills
(1) Before using the new machine of the air leg rock drill, it is necessary to disassemble and clean the internal parts and remove the rust-proof oil. When reassembling, lubricate each mating surface. Use compressed air to blow away the dirt in the air supply pipe and joints to prevent it from entering the machine and wearing parts.
(2) Check whether the shape and length of the tail of the
air leg rock drill, the size and depth of the water pinholes meet the requirements; whether the center hole is unobstructed. If the drill tail is "piled" or cracked, it should be replaced in time according to the situation.
(3) Give air or water to the air-leg rock drill and observe whether it is clear. Do not punch holes, and do not remove the needle to avoid damage to the valve sleeve.
(4) Always carefully check whether the joints of the air-leg rock drill are fastened, whether the air intake elbow is fastened, and whether the operating handles are reliable and flexible, so as to prevent the loose parts from hurting people or affecting the normal operation of the machine.
(5) Before the rock drill is running, the oiler needs to be filled with lubricating oil and adjust the oil quantity. During the work, the oil injector should be filled with oil once every lh. No oil-free operation is allowed. For floor-type lubricators, you must pay attention to whether the installation direction is correct.
(6) After drilling the
air leg rock drill, remove the water pipe and perform a light operation to blow off the residual water droplets in the machine to prevent the internal parts from rusting. Then place the rock drill and air leg in a safe and clean place to prevent smashing during the cannon firing. Bad.
(7) A special person for the gas leg rock drill should be responsible for the maintenance. After work, carefully check whether all parts are damaged, and repair it in time if there is a failure.
(8) When handling failures or overhauling pneumatic rock drills downhole, they should not be carried out on the driving face, but in the downhole repair department with better conditions.
(9) If the used tools of the
air leg rock drill need to be stored for a long time, they should be disassembled, cleaned and sealed with oil.
