1. Alignment: 1) In case of special circumstances, the hole position deviation shall generally not exceed 0.2 meters. The maximum shall not exceed 0.4 meters. The holes and the row distance and azimuth angle should be consistent as much as possible. 2) Cut off the power supply of the travel motor. 3) Turn on the power supply of the working system. 4) Flip the main command switch of the electrical operation table to the manual position. Remove the wrench from the brazing bracket. 5) Lift the drill tool slightly. Stop until the head is about 30 mm above the ground. 6) Slowly lower the drill tool. 7) Install the dust trap.
2. DTH drilling rig opening, drilling: 1) Start the exhaust fan. 2) Start the slewing mechanism. 3) Pull the impactor control valve to the half-open position. 4) Lower the drilling tool. When the head touches the rock, the lift propulsion mechanism descend button is turned on. The impactor then starts working, making holes. If jamming or deflection occurs, the drilling tool should be lifted immediately; Repeat the above sequence until the impactor starts drilling normally. 5) Open all the impactor control valves or wrench them to the appropriate opening position. According to the condition of the rock. Flip the master switch to the automatic position. 6) Stop lowering the drilling tool. The push control valve lever is wrenched to the pressure regulating position for pressure regulation rock drilling. 7) If the rock is soft or broken, yellow mud should be loaded into the hole for wall protection.
3. Precautions when drilling normally: 1) The temperature rise is normal. Each motor should have no abnormal noise. 2) No noise during operation. The middle gear meshes normally. 3) Adjust the axial pressure of the drilling tool at any time, according to the rock situation at the bottom of the hole and the ammeter reading. Prevent overloading of the slewing machine. When the current exceeds the rated value, the drilling tool should be immediately raised and checked and disposed of normally before the operation can continue.
4. When the carriage swings seriously, the axial pressure should be reduced.
5. When the air pressure is lower than 4 kg/cm2, drilling should be stopped. No bridge pressure phenomenon.
6. The wire rope of the lifting propulsion mechanism should be arranged neatly. The rope head is firm. Pay attention to adjusting the tightness level of the wire rope at all times.
7. When jamming occurs, it should be disposed of according to the specific situation. The drill pipe must not be forcibly lifted. In case of thick interlayer or water coming out of the hole, drill first, and then stop the air to avoid blocking the impactor.
8. When the wind pressure suddenly decreases and the impactor does not sound. The cause should be ascertained and dealt with in a timely manner. In order to avoid accidents such as overloading or pulling the wire rope.
9. The limit switch of the push cylinder frame should always be flexible and effective.
