Installation of DTH drilling unit:
1. Prepare the rock drilling space, the size of the space can be determined according to the model and drilling method used for drilling.
2. Lead the gas and water pipelines, lighting lines, etc. to the vicinity of the working point for use.
3. According to the needs of hole position design, ensure the reliable positioning of the drilling rig.
Inspection before DTH drilling < br/>
1. When starting the work, you should carefully check whether the gas and water pipelines are firmly connected, especially the connection between the feng shui pipe joint and the feng shui pipe must be firm to prevent trip injury to people, and air leakage is not allowed at each connection.
2. Check whether the lubricator has been loaded with organic oil.
3. Check whether the screws, nuts, joints, etc. of each part have been tightened, and whether the various positioning is firm and reliable.
Drilling operation procedure and unloading method:
1. When opening the hole, first drill with small impact work, propulsion force and low speed, in order to facilitate the positioning of the brazing head, when the brazing head is drilled into about 10 cm, and then impact with the full damper, and appropriately increase the propulsion force, increase the speed, carry out normal rock drilling work, after drilling a drill pipe to stop the fan motor operation and stop the impact of air supply and water, insert the fork into the drill pipe groove of the brazing device, so that the wind motor reverses, the slide plate retreats, so that the joint is disconnected from the drill pipe, and then the second drill pipe is connected for drilling, and so on.
2. Unloading method: The drill pipe unloading rod is semi-automatic, which is realized by relying on the rod unloader, carrier and the reversal of the two forks and their fan motors. When unloading the rod, the rotary machine moves back When the second groove of the drill pipe is directly opposite to the square frame of the brazing gear, insert the second slot firmly with a fork, and then reverse the motor, when the four-square frame of the rod unloader is directly opposite to the first slot of the drill pipe, insert the second fork firmly, take out the first fork, manipulate the propulsion cylinder, so that the rod unloader drives the drill pipe back, when the second groove of the second drill pipe is aligned with the bracket groove, reverse the motor, when the screws of the two drill pipes are disengaged and remove the first drill pipe, so that each drill pipe is removed in turn.
Notes during operation:
1. Pay attention to check the screw and nut connection of the air-water circuit, as well as the fixing of the frame and the host.
2. Observe the operating status of the lubricator from time to time, and pay attention to check the lubrication of the wind engine and impactor.
3. Clean the impactor and wind turbine regularly and observe whether the motor blades are damaged by gasoline or diesel.
4. To prevent the drill pipe from tripping, reverse rotation is not allowed during drilling.
5. If the machine stops working in a short time, you need to apply a small amount of air pressure to avoid sand entering the impactor. If the machine does not operate for a long time, then the impactor should be located 1-2 meters from the bottom of the hole. Fix again.
6. Pay attention to the sound of the impactor and the normal operation of the machine being operated, and if you find any abnormalities, stop immediately.
7. When adding a new drill pipe, pay special attention to cleaning the drill pipe so that sand will not enter the impactor and damage the machine or cause downtime accidents.
8. If there is water on the working face, use a large diameter drill bit at the opening, then insert the casing and ground the casing 100-200 mm to prevent mud from entering the hole and being exposed to
