In the initial position, the rotary drilling power head is positioned at the topmost end, and at the moment, the three horizontal hydraulic cylinders 8 are all in a contracted state.
When the manipulator of the submarine drilling machine grabs a first drill rod (the core drill bit with a rope is arranged in the submarine drilling machine) to the center of the drill hole, the sliding plate 10 moves downwards along the mast, so that the rotary drilling power head moves downwards, when the conical threads at the bottom of the driving shaft 19 enter the drill tool, the hydraulic system is used for extending the three horizontal hydraulic cylinders 8, the three clamping claws 12 extend out of the clamping drill tool and drive the hydraulic motor 1 to work, so that the driving shaft 19 rotates at a low speed, in the butting process, the horizontal hydraulic cylinders 8 move upwards along the chuck connecting shaft 8 and compress the four high-elasticity springs 13, the butting of the driving shaft 19 and the first drill rod is completed, the three horizontal hydraulic cylinders 8 shrink and loosen the drill tool, and at the moment, the three horizontal hydraulic cylinders move downwards under the tension of the high-elasticity springs 13 to restore the initial state. Then, the hydraulic motor 1 is simultaneously driven to rotate at a high speed and the slide plate 10 is moved downward, so that the drilling coring operation is performed. After the first drilling sampling is completed, the drill rod is clamped again by the three horizontal hydraulic cylinders 8, at the moment, the gear 11 is driven to rotate by the two rotary motors 4, so that the drill rod and the driving shaft 19 are tripped, at the moment, the three horizontal hydraulic cylinders 8 can move downwards, and the four high-elasticity springs 13 are in a stretching state. After the tripping is completed, the drill rod in the drilled hole is clamped by using the clamping seat of the drilling machine, and the three horizontal hydraulic cylinders 8 are loosened and move upwards under the contraction force of four high-elasticity high-strength springs 13. At this time, the rotary power head is lifted to the highest point, and the first rope core drill is recovered by the fishing spearhead. After recovery is completed, the manipulator of the submarine drilling machine is used for grabbing a second rope core drilling tool, when the manipulator moves to the center of a drilling hole, the rotary power head moves downwards, when the top of the second rope core drilling tool enters the middle of the three clamping claws 12, the three horizontal hydraulic cylinders 8 are driven to extend out, the rope core drilling tool is clamped, then the manipulator is loosened, and then the manipulator is located at an idle position. And then the rotary drilling power head is driven to move downwards until the second wire-line coring drilling tool enters the first section of drill rod, the three horizontal hydraulic cylinders 8 shrink simultaneously, and the wire-line coring drilling tool is loosened to enable the wire-line coring drilling tool to freely fall into the first section of drill rod, so that the second wire-line coring drilling tool is distributed. At this time, the rotary drilling power head is lifted to the highest point, the mechanical gripper is utilized to grasp the drill rod, when the second drill rod is positioned right above the drill hole, the butt joint mode is utilized to finish the butt joint of the driving shaft 19 and the second drill rod, after the butt joint is finished, the rotary power head moves downwards, the driving shaft 19 is driven to rotate simultaneously, the butt joint of the second drill rod and the second drill rod in the hole is finished, and after the butt joint is finished, the clamping seat of the drilling machine is loosened, and the drilling sampling of the second section of rock core is performed. According to the method, the butt joint between the sampling of the multi-section core and the drill rod is completed.
When the coring operation is completed, the removal of the drive shaft 19 from the uppermost drill rod is completed using the above-described removal method. After the disassembly is completed, the three horizontal hydraulic cylinders 8 are in a state of clamping the drill rod, then the rotary drilling power head is driven to integrally move upwards, and meanwhile the drill rod in the hole moves upwards together to complete the pulling-out work of the drilling tool. When the top of the second drill rod at the upper end moves to the clamping seat of the drilling machine, the upper end of the second drill rod is clamped, and the two rotary motors 4 are used for driving the gear 11 to rotate, so that the first drill rod at the upper end and the second drill rod are tripped. The tripping method is used for completing the tripping between the drill rods and recovering the drill rods to the drill rod warehouse until the recovery of the last drill rod is completed.
Compared with a conventional rotary hydraulic motor, the embodiment has the advantages that the clamping device of the drill rod is added, the rotary power head can be used for independently completing the butt joint and disassembly of the driving shaft 19 and the drill rod, the disassembly time between the drill rods can be greatly reduced, and the working efficiency of the submarine drilling machine is improved; the shaft cylinder 3, the hollow shaft 17 and the driving shaft 19 are connected through two groups of thrust bearings 14, the hollow shaft 17 and the driving shaft 19 can rotate independently, and therefore the effects that the driving shaft 19 drives a drill rod to drill and the hollow shaft 17 clamps or loosens the drill rod are not affected; the horizontal hydraulic cylinder 8 clamping structure is adopted to clamp the top of the rope core drill, the mast is utilized to drive the vertical downward displacement of the slide plate 10, and the rope core drill can be accurately thrown into the drill rod.
