A, the installation of units:
1, ready to drill space, space model can be used according to the borehole and drilling methods.
2, the gas water (water dust removal) piping, lighting and other led to near the working point.
The number of the 3, according to the design requirements, guarantee reliable positioning drilling rig.
Second, the homework before the check:
1, when he began to work, should be carefully check gas, water (water dust removal) whether the pipeline connection is firm, especially the wind pipe joint and the wind pipe connection must be strong, to prevent tripping hurt, all the connection place is allowed to leak leakage phenomenon.
2, check the oil sprayer is equipped with oil (should not be loaded too full).
3, check each part of the place such as screws, nuts, joint whether have tightened, a variety of positioning is solid and reliable.
Three, perforating operation procedure and method of unloading rod:
1, when open hole, start with small impact, propulsion, and the low speed drilling, so that the drill bit positioning, (need to dust, to appropriate water to reduce dust) drill bit drilling 10 centimeters or so, with full throttle, and appropriately increase the propulsive force, improve the speed, (when the dust gets water mixture keep appropriate ratio), make the normal drilling work, drilling through a pipe to stop the wind motor operation and stop to the impacter plenum to send water, fork inserted into the groove of the soldering machine, drill pipe, make the wind motor reversal, slide backward, make joint release with drill, then the second drill pipe drilling, so work continuously.
2, unloading rod method: the drill pipe unloading rod is half automation, depend on unloading rod machine, soldering machine and the two forks and match the wind motor reversal. Unloading rod, the rotary engine back when the second slot pipe (drill pipe joint end on drill pipe in the middle of slot) and four boxes are pair of brazing, use a fork stuck in the second slot, then reverse the motor, four box when unloading rod and the pipe first groove (drill pipe joint end on drill pipe end groove) is pair, with the second fork stuck, take out the first fork (Joe bit four box fork), manipulation of the cylinder, to drive the drill pipe (one-way of unloading rod device, when the second drill pipe of the second tank of bending soldering machine, reversing motor, when the two pipe screw off after the first drill pipe, so in order to unload the drill pipe.
Four, should be paid attention to in the operating items:
1, always pay attention to check the gas and water (water dust removal) road sections of screw, nut, joint connection and fastening frame and host.
2, pay attention to the oil mist detector at work, check the lubrication condition of wind motor, impact device.
3, intervals, clean with gasoline or diesel, wind motor, observe motor damage of the blade.
4, do not allow the reverse when drilling, lest the drill pipe tripping.
5, the machine in a short period of time to stop work, to give a small amount of compressed air, to avoid sediment impact device inside, if in a long time to stop work, impact device must be mentioned from 1-2 meters shall be fixed at the bottom of the bore.
6, the work should pay attention to the voice of the impacter and the workings of the machine is normal, found abnormal phenomenon should immediately stop check.
7, add a new drill pipe, it is important to pay special attention to the drill pipe inside clean, to avoid sand mixed with percussive internal attaint parts or outage accidents. (general use compressed air to blow, wash several times).
8, surface water, open a hole with a large diameter drill bit, and then inserted into the casing, and the casing where the 100-200 mm long, to prevent slag mud into the hole.
Five, machine maintenance and lubrication:
1, each at the end of the working class, must clear out the dirt on the surface of the machine.
2, it is strictly prohibited in the demolition work surface discharge, (into components easy to handle the exception), in order to avoid missing parts and key parts of the damaged parts.
3, add oil to oil mist detector on a regular basis, to ensure that the control valve, the wind motor and impact appliance has the good lubrication.
4, reducer oil mixed with calcium base grease lubrication, regular add lubricant, lubricant about a third of the box body gap - two-thirds of advisable, to ensure that the reducer lubrication.
5, promote integration due to skateboard and the relative motion of the carriage in the carriage and the pressure plate and slide friction losses, slight friction losses may be removed when adjust pad under the pressure plate, friction losses when the heavier in linking piece, skateboard, or carriage,
In order to ensure high precision drilling.
