Use, maintenance and common fault treatment of pneumatic anchor drill
Use of (I) Air Coal Drill
(1) The operator must carefully study and master the performance and operation methods of the air drill.
(2) Check whether all parts of the machine are complete and whether the fasteners are reliable. Compressed air must be clean,The pressure should be controlled at 0.4~0.63MPa. The gas source shall be fed into the bolter through the pressure limiting valve. External water and air sourceBefore being fed into the pneumatic anchor drill, a special valve is provided. Before the anchor drill is started, the handlebar should be closed.Status. The oil mist device shall be installed on the intake pipe, and sufficient No. 20 mechanical oil shall be added into the oil mist device to adjust the oil mist device.Air intake, so that the moving parts are effectively lubricated.
(3) No-load test shall be carried out before drilling operation. The test operation is as follows: press down the motor control handle and move it.Press open a small angle to let the drill pipe rotate slowly; press down the water control handle, and water gushes out of the drill pipe joint.Gradually contact the drill bit with the upper body to drill the locating hole. After the location of the hole is determined, according to the hardness of the coal,Control the opening of the valve for drilling operations. During the drilling process, properly adjust the angle of each valve, that is, adjustableKnots drilling speed.
(II) maintenance and common fault handling
1. Routine maintenance
(1) Lubricate the reducer body, inject mechanical oil or butter every month, and the temperature of the reducer body shall not exceed 50Degree.
(2) Maintenance. ① Check whether the connecting moving parts and fasteners are loose; ② Check the parts110Whether the seal is reliable; ③ regularly remove the rear end cover of the drilling rig and check the lubrication of moving parts.
(3) Maintenance. During the long-term operation of the anchor drill, due to wear and corrosion, the lossThe original accuracy and performance should be checked and the necessary wearing parts should be replaced. When necessary, the user according to the useConditions, mandatory maintenance cycle.
