[0002] The drilling rig power head is one of the key components of the drilling rig, which is usually composed of a drive device, a transmission mechanism and an output shaft. It mainly provides rotational power and feed power for the drill rod of the drilling rig, so that the drill rod can cut the formation rock and achieve the purpose of drilling. In actual drilling operations, construction personnel often need to adjust the depth and position of the drilling hole according to different geological conditions and engineering requirements. In order to adjust the drilling depth and position of the drill rod and improve the adaptability of the drilling rig, a sliding structure is generally equipped between the drilling rig and the power head.

The eight connecting blocks 156 are divided into four groups, and a first shell 158 is fixed between the opposite ends of each group of connecting blocks 156. A second shell 159 is provided on one side, and the four first shells 158 and the four second shells 159 are divided into two groups. Each sliding slide rod 2 is movably sleeved between the interior of each group of first shells 158, and each sliding slide rod 2 is movably sleeved between the interior of each group of second shells 159. Two symmetrical arc blocks 1510 are fixed to the outer wall of each second shell 159. The surface of each arc block 1510 is threaded with a hand screw 1511. The eight hand screws 1511 are divided into four groups. The threaded ends of each group of hand screws 1511 are threadedly connected to the outer wall of each first shell 158, and the inner wall of each second shell 159 is provided with a liquid outlet 1512.

The oil injection end of each group of atomizing nozzles 157 movably penetrates the outer wall of each first shell 158, and the oil injection end of each group of atomizing nozzles 157 movably penetrates the outer wall of each second shell 159.

[0039] In this embodiment, when the two sliding rod sleeve assemblies 3 move at the same time, the auxiliary mechanism 15 (except the oil tank 155 and the oil pipe 154) and the oil outlet end of the oil pipe 154 will also move accordingly. When the lubricating oil on the surface of the two sliding rods 2 dries up and needs to be refueled, the oil pump 153 is directly started by the prepared controller. The started oil pump 153 will extract the lubricating oil in the oil tank 155 with the cooperation of the oil pipe 154, and then transport it to the inside of the diverter 150, and then divert it to the inside of the two tee pipes 151, and then divert it to the inside of the corresponding two U-shaped parts 152. When the lubricating oil enters When the lubricating oil enters the interior of each U-shaped member 152, the lubricating oil entering the interior of each U-shaped member 152 will respectively enter the interior of the two atomizing nozzles 157 connected thereto, and then the lubricating oil entering the interior of each atomizing nozzle 157 will be sprayed out in an atomized manner, sprayed on the surface of the sliding slide rod 2 in the space formed by the first shell 158 and the second shell 159, and then the hydraulic transmission system, the cylinder body 5, the cylinder rod 6 and the previous linkage parts are used to make the two slide rod sleeve assemblies 3 move back and forth, that is, the slide rod sleeve assembly 3 moving back and forth drives all the atomizing nozzles 157 (fan-shaped nozzles) and the auxiliary mechanism 15. The first shell 158 and all the second shells 159 move to realize the oiling operation on the surface of the sliding rod 2. When the lubricating oil formed by the accumulation of lubricating oil mist appears on the inner wall of the space composed of the first shell 158 and the second shell 159, the lubricating oil inside the above space can be discharged with the cooperation of the corresponding liquid outlet 1512. When the oiling operation is completed on the surfaces of the two sliding rods 2, the oil pump 153 is turned off by the prepared controller, and then the movement of the drilling rig power head body 13 is stopped by the cooperation of the hydraulic transmission system, the cylinder body 5, the cylinder rod 6 and the previous linkage parts. When it is necessary to replace one of the atomizers When replacing the atomizing nozzle 157, remove the two corresponding hand screws 1511, and then move the corresponding second shell 159. The moving second shell 159 will drive the two arc blocks 1510 connected thereto to move. When the atomizing nozzle 157 to be replaced is exposed, stop the moving operation of the corresponding second shell 159 directly, and then remove the atomizing nozzle 157 to be replaced, replace it with a new atomizing nozzle 157, and then reset the corresponding second shell 159 to its original position, and then use the corresponding arc block 1510 and the corresponding hand screw 1511 to fix the second shell 159 to the first shell 158 together.

When the drilling rig power head body 13 needs to be moved At this time, the hydraulic transmission system, the two first cylinder ears 4, the first bearing, the first pin shaft 11, the cylinder body 5 and the slide plate 1 are used to cooperate to move the connecting end of the cylinder rod 6. Then, the moving connecting end of the cylinder rod 6 will drive the sliding connecting plate 7 to move with the cooperation of the second pin shaft 12, the second bearing and the two second cylinder ears 9. Then, the moving sliding connecting plate 7 will drive the drilling rig power head body 13 to move stably with the cooperation of multiple reinforcement plates 8, two mounting platforms 10, two sets of sliding rod seats 14, two sliding slide bars 2 and two sliding rod sleeve assemblies 3 (two sliding sleeve bases 30, four sliding sleeve bodies 31, eight sliding sleeve tile covers 32, eight dust rings 33 and four steel sleeves 34).

When the lubricating oil on the surface of the two sliding slide rods 2 dries up and needs to be oiled, the oil pump 153 is directly started by the prepared controller. At this time, the started oil pump 153 will, with the cooperation of the oil pipe 154, draw out the lubricating oil in the oil tank 155, and then transport it to the inside of the diverter 150, and then divert it to the inside of the two tee pipes 151, and then divert it to the corresponding two U-shaped parts 1 52, when the lubricating oil enters the interior of each U-shaped member 152, the lubricating oil entering the interior of each U-shaped member 152 will respectively enter the interior of the two atomizing nozzles 157 connected thereto, and then the lubricating oil entering the interior of each atomizing nozzle 157 will be sprayed out in an atomized manner, sprayed on the surface of the sliding slide rod 2 in the space composed of the first shell 158 and the second shell 159, and then the hydraulic transmission system, the cylinder body 5, the cylinder rod 6 and the previous linkage parts are used to make the two slide rod sleeve assemblies 3 move back and forth, that is, the slide rod sleeve assembly 3 that moves back and forth drives all the atomizing nozzles 157 (fan-shaped nozzles), all the first shells 158 and all the second shells 159 on the auxiliary mechanism 15 to move,To realize the oiling operation on the surface of the sliding rod 2, when the lubricating oil formed by the accumulation of lubricating oil mist appears on the inner wall of the space formed by the first shell 158 and the second shell 159, the lubricating oil inside the above space can be discharged with the cooperation of the corresponding liquid outlet 1512. When the oiling operation is completed on the surfaces of the two sliding rods 2, the oil pump 153 is turned off by the prepared controller, and then the movement of the drilling rig power head body 13 is stopped by the cooperation of the hydraulic transmission system, the cylinder body 5, the cylinder rod 6 and the previous linkage parts. When one of the atomizing nozzles 157 needs to be replaced, it is removed at this time. The corresponding two hand screws 1511 are tightened, and then the corresponding second housing 159 is moved. At this time, the moving second housing 159 will drive the two arc blocks 1510 connected thereto to move. When the atomizing nozzle 157 to be replaced is exposed, the moving operation of the corresponding second housing 159 is directly stopped, and then the atomizing nozzle 157 to be replaced is removed and replaced with a new atomizing nozzle 157. Then the corresponding second housing 159 is reset to its original position, and then the corresponding arc block 1510 and the corresponding hand screws 1511 are used to fix the second housing 159 and the first housing 158 together.
