The crane is then used to lower the drill bit or the like of the breaking assembly 3, during which the opening and closing of the third plate 105 and the fourth plate 106 is engaged, and after lowering to the uppermost drill rod 31, the third plate 105 and the fourth plate 106 are in a fifth position, so that the third plate 105 and the fourth plate 106 are closed, suspending the drilling tool on the third plate 105 and the fourth plate 106.

The following operation program is also the lower stage of the sizing operation program.

And hanging a steel wire rope under the hook head of the crane, hanging a lower section of a drill rod 31 under the steel wire rope, hanging a drill rod of 6m to an orifice, connecting the drill rod 31 to upper flanges on the third plate 105 and the fourth plate 106, tightening the connecting bolt by using a pneumatic wrench, and manually removing a hanging rope on the hook head of the crane.

Two workers go up to the mounting platform 10 along the ladder and drill into the sleeve pipe transition joint below the conversion assembly 5, command to start the second driving piece 8, make the conversion assembly 5 go down relative to the crossbeam 6, the worker takes off the wire rope and the lower section of the hoist of the drill rod 31, command the first driving piece 7 to put down about 200mm, connect the lower flange of the second connecting piece 33 and the upper flange of the sub drill rod by bolts and tighten by a pneumatic wrench. Manually snapping the flap first sub-plate 1021 and the third sub-plate 1031 onto the second sub-plate 1022 and the fourth sub-plate 1032, the worker drills the bushing transition joint, and actuates the cylinder to place the second sub-plate 1022 and the fourth sub-plate 1032 in a fourth position, in other words, the second sub-plate 1022 and the fourth sub-plate 1032 are far away from each other.

The conversion component 5 goes down again, a worker on the surface of the mounting platform 10 takes off the lifting appliance of the sleeve 4, commands the butt joint of the sleeve transition joint and the sleeve 4, and carries out manual operation to connect the lateral fastening bolt.

Three, the casing 4 and the RCD drill bit are drilled simultaneously

The rotary power of the sleeve 4 and the RCD drill bit during drilling is realized by a full-circle slewing drilling machine, the first driving piece 7 and the second driving piece 8 are in free states before drilling, namely the conversion component 5 is lifted by the full-circle slewing drilling machine along with the sleeve 4 up and down, and the lifting of the RCD drilling tool system depends on the first driving piece 7. The sliding part 34 and the second connecting part 33 can slide 2m relatively, the advancing speed of the casing 4 and the RCD drilling tool can be fast or slow, the distance between the casing and the RCD drilling tool cannot exceed 2m, when one party is too fast, idling (full-weight lifting without pressing to the bottom of a hole) is adopted, and the advancing of the other party is waited to follow up.

When the casing 4 and the RCD drilling tool are drilled in place (as in the drilling process), the drilling operation of the drilling tool is finished. At this time, the upper opening of the flange of the drill rod 31 is 50-115mm below the datum level, and the upper opening of the sleeve 4 is 650-750mm below the datum level. Note that the direction of rotation of the casing 4 is anticlockwise and the direction of rotation of the RCD tool is clockwise.

Four, add chi

After 6m of casing 4 and drill bit are drilled, the connection between the switching assembly 5 and the casing 4 is first released, the first driving member 7 is lifted, the oil cylinder of the switching assembly 5 is lifted, the third plate 105 and the fourth plate 106 are in the fifth position, in other words, the third plate 105 and the fourth plate 106 are closed, and the first matching portion 1051 and the second matching portion 1061 clamp the drill rod 31.

Five, RCD drill bit is independently drilled

And after the fifth step is finished, repeating the fourth step, wherein the footage is advanced by 6m in each cycle operation until the simultaneous drilling depth of the casing 4 and the RCD drill bit reaches the designed position of the casing 4. Then the casing 4 is cut off, the first driving member 7 is lifted to simultaneously lift the cut casing 4 and the RCD tool, and the connection between the cut casing 4 and the conversion assembly 5 is removed after the tool is locked according to the four-step reverse operation procedure. The flange connection between the second connector 33 and the drill rod 31 is released. The first section 11 is tilted to free up the opening crane working space, the crane lifts the severed casing 4, the crane lifts a section of 3m long drill pipe 31, the worker bolts it to the underlying flange, and then lifts the casing 4. After the connection of the casing 4 and the drill rod 31 is completed according to step four, the drilling of the drilling tool alone can be started, except that the footage per cycle is 3 m.

Sixthly, the sleeve 4 is drilled separately

The sleeve 4 connector of the lower opening of the conversion assembly 5 is separated from the sleeve 4, the conversion assembly 5 is started to the upper end, and the first driving piece 7 is not moved, so that the sleeve 4 can be driven by the full-rotary drilling machine to drill independently.

Seven, pulling out the drill

After drilling, the casing 4 is left in the hole as a casing of the drill hole, and all RCD drilling tools need to be pulled out. Before the drill is taken off, the drill rod 31 unloading platform is hoisted into the drill frame by a crane and is in place. The operation is carried out according to the lifting capacity of the crane in three conditions.

The first situation is as follows: the hoisting weight of the crane in the center of the drill hole is larger than the weight of all drilling tools.
