Description

Technical Field

[0001] The present invention relates to the technical field of drill rig power heads, and particularly to a high-frequency eccentric vibration acoustic power head for a drill rig. Background Art

[0002] A drill rig is a mechanical device that drives a drill string to drill underground in exploration or mineral resource (including solid minerals, liquid minerals, gas minerals, etc.) development to obtain physical geological data. Its main function is to drive the drill string to break the rock at the bottom of the hole and lower or lift the drill string in the hole. The eccentric vibration type acoustic power head used in a drill rig usually adopts two eccentric wheels. When the power is small, the vibration effect may not be ideal; when the power is too large, although the vibration is obvious, the noise will also increase accordingly, making it difficult to achieve high-frequency vibration, and a large amount of heat is generated during operation, which will reduce the service life of the acoustic power head of the drill rig. Summary of the Invention

[0003] The main purpose of the present invention is to provide a high-frequency eccentric vibration acoustic power head for a drill rig, which can effectively solve the problems in the background art.

[0004] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0005] A high-frequency eccentric vibration acoustic power head for a drill rig, including a power head. Installation rings are fixedly arranged at both the upper and lower ends of the power head. A cavity is arranged inside the power head. A high-frequency vibration component is arranged inside the cavity. Four groups of cooling components are arranged on the high-frequency vibration component. A driving structure is arranged outside the power head. The high-frequency vibration component includes two fixed seats fixedly arranged near the upper and lower sides inside the power head. Square bars are movably arranged inside both of the two fixed seats. A double-shaft motor is fixedly arranged between the two square bars. First rotating shafts are fixedly arranged on the front and rear sides of the double-shaft motor. First bevel gears are fixedly arranged on the outer sides of the two first rotating shafts. Top seats are fixedly arranged on the outer sides of the two square bars. Return springs are sleeved between the top seats and the fixed seats on the outer sides of the two square bars near the top seats. Cross frames are fixedly arranged on both sides of the two top seats. Vertical frames are fixedly arranged at the front and rear ends of the two cross frames. Second rotating shafts are rotatably arranged inside the two cross frames. Second bevel gears are fixedly arranged at positions near the inner sides of the two cross frames on the outer sides of the two second rotating shafts. Eccentric wheels are fixedly arranged on the outer sides of the two first rotating shafts and the two second rotating shafts.

[0006] Preferably, the cooling component includes a rotating ring rotatably arranged outside two first rotating shafts and a second rotating shaft. Circular rods are fixedly arranged at the upper and lower ends of the rotating ring. Piston blocks are movably arranged on the opposite sides of the upper and lower parts of the two circular rods. Vent pipes are movably arranged outside the two piston blocks. A plurality of ventilation openings are formed in the two vent pipes. Rings are fixedly arranged inside the two vent pipes. A fixing frame is fixedly arranged at one end of the ring. A fixing piece is fixedly arranged at the central position of the fixing frame. A plurality of rotating rods are movably arranged inside the fixing piece. Cover plates are fixedly arranged outside the plurality of rotating rods. Empty shells are fixedly arranged at the positions corresponding to the plurality of rotating rods inside the ring. A torsion spring is arranged outside the rotating rod close to the inner side of the empty shell.

[0007] Preferably, the square bar extends to the outside of the power head, and the two first bevel gears are arranged inside the two vertical frames.

[0008] Preferably, the two first bevel gears and the two second bevel gears are meshed with each other, and the cross frame and the vertical frame are cross-connected.

[0009] Preferably, the two second bevel gears and the first rotating shafts are arranged inside the cross frame and the vertical frame.

[0010] Preferably, the circular rod is connected to the piston block through a spherical ball, and the piston block is hermetically attached to the vent pipe.

[0011] Preferably, the vent pipe is fixedly arranged inside the power head, the ventilation openings communicate with the inside of the vent pipe, and the plurality of rotating rods and cover plates are evenly arranged outside the fixing piece.

[0012] Preferably, the plurality of rotating rods are movably arranged with the corresponding plurality of empty shells, and the two ends of the torsion spring are respectively inserted into the inside of the empty shell and the rotating rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The two groups of first rotating shafts driven by the dual-axis motor, along with the two groups of first bevel gears and eccentric wheels connected thereto, rotate. The rotation of the two groups of first bevel gears respectively drives the two groups of second bevel gears meshing on both sides to rotate simultaneously. The two groups of second rotating shafts drive the two groups of eccentric wheels connected thereto to rotate at the same time. By driving the four groups of eccentric wheels to rotate together, the inertia generated by the rotating four groups of eccentric wheels drives the dual-axis motor and the two square bars to slide up and down along the two fixed seats. The movement of the two square bars drives the top seat, the cross frame, and the vertical frame to move together. The two top seats move up and down, respectively squeezing the reset springs on the upper and lower sides. Through the elasticity of the reset springs, the vibration of reciprocating up and down movement is realized, and the generated vibration is transmitted to the drill bit. The use of multiple groups of eccentric wheels provides a stronger shock absorption function, a more uniform and firm support, a more stable and smooth experience, and more effectively completes the high-frequency eccentric vibration acoustic wave work compared with the work of the traditional two-piece eccentric structure.

[0015] 2. Through the up and down movement of the four groups of second rotating shafts, the four groups of rotating rings sleeved thereon are respectively driven to move up and down, pulling or pushing the two round bars and the piston blocks to perform up and down piston movement in the two vent pipes. When the piston block is pushed into the vent pipe by the round bar, the hot air generated in the cavity enters the vent pipe through the vent hole. When the piston block moving towards the inside of the vent pipe accelerates to push the hot air towards the side provided with the fixed frame, when the airflow on one side impacts the cover plate, the greater pressure will push the cover plate to drive the rotating rod to rotate along the fixed part and the empty shell (as Figure 7 ), while tightening the torsion spring. Similarly, when pulling the piston block, it accelerates the entry of external air. The upper and lower two vent pipes achieve one-in and one-out during the operation of the high-frequency vibration component, discharging the hot air generated inside. At the same time, the setting of multiple vent pipes accelerates the circulation of the internal gas, improves the internal working environment, reduces the low efficiency caused by high temperature, and ensures safety.

Detailed implementation manners

[0025] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0026] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is the relative orientation or position relationship, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0027] Please refer to Figures 1-8, an embodiment provided by the present invention: a high-frequency eccentric vibration acoustic power head for a drilling rig, including a power head 1. Installation rings 2 are fixedly arranged at both the upper and lower ends of the power head 1. A cavity 3 is arranged inside the power head 1. A high-frequency vibration assembly 4 is arranged inside the cavity 3. Four groups of cooling assemblies 5 are arranged on the high-frequency vibration assembly 4. A driving structure 6 is arranged outside the power head 1. The high-frequency vibration assembly 4 includes two fixed seats 41 fixedly arranged near the upper and lower sides inside the power head 1. Square bars 42 are movably arranged inside both of the two fixed seats 41. A double-shaft motor 43 is fixedly arranged between the two square bars 42. First rotating shafts 44 are fixedly arranged on the front and rear sides of the double-shaft motor 43. First bevel gears 45 are fixedly arranged on the outer sides of the two first rotating shafts 44. Top seats 46 are fixedly arranged on the outer sides of the two square bars 42. Return springs 47 are sleeved between the outer sides of the two square bars 42 near the top seats 46 and the fixed seats 41. Cross frames 48 are fixedly arranged on both sides of the two top seats 46. Vertical frames 49 are fixedly arranged at the front and rear ends of the two cross frames 48. Second rotating shafts 410 are rotatably arranged inside the two cross frames 48. Second bevel gears 411 are fixedly arranged at the positions near the inner sides of the two cross frames 48 on the outer sides of the two second rotating shafts 410. Eccentric wheels 412 are fixedly arranged on the outer sides of the two first rotating shafts 44 and the two second rotating shafts 410.

[0028] The square bars 42 extend to the outside of the power head 1. The two first bevel gears 45 are arranged inside the two vertical frames 49. The two first bevel gears 45 and the two second bevel gears 411 are meshed with each other. The cross frames 48 and the vertical frames 49 are cross-connected. The two second bevel gears 411 and the first rotating shafts 44 are both arranged inside the cross frames 48 and the vertical frames 49.

[0029] The double-shaft motor 43 drives the two first rotating shafts 44 and the two connected first bevel gears 45 and eccentric wheels 412 to rotate. The rotation of the two first bevel gears 45 respectively drives the two second bevel gears 411 meshed on both sides to rotate together. The two second rotating shafts 410 simultaneously drive the two connected eccentric wheels 412 to rotate. By driving the four eccentric wheels 412 to rotate together, the inertia generated by the rotation of the four eccentric wheels 412 drives the double-shaft motor 43 and the two square bars 42 to slide up and down along the two fixed seats 41. The movement of the two square bars 42 respectively drives the top seats 46, the cross frames 48, and the vertical frames 49 to move together. The two top seats 46 move up and down, respectively squeezing the upper and lower return springs 47. The vibration of the up-and-down reciprocating motion is realized through the elasticity of the return springs 47. The generated vibration is transmitted to the drill bit. By using multiple eccentric wheels 412, compared with the work of the traditional two-piece eccentric structure, it provides stronger shock absorption function, more uniform and firm support, and a more stable and smooth experience, and more effectively completes the high-frequency eccentric vibration acoustic work.

[0030] The temperature reduction component 5 includes a rotating ring 51 rotatably arranged outside two groups of first rotating shafts 44 and second rotating shafts 410. Circular rods 52 are fixedly arranged at the upper and lower ends of the rotating ring 51. Piston blocks 53 are movably arranged on the opposite sides of the upper and lower parts of the two circular rods 52. Vent pipes 54 are movably arranged outside the two piston blocks 53. A number of ventilation openings 55 are formed in the two vent pipes 54. Circular rings 56 are fixedly arranged inside the two vent pipes 54. A fixing frame 57 is fixedly arranged at one end of the circular ring 56. A fixing member 58 is fixedly arranged at the central position of the fixing frame 57. A number of rotating rods 59 are movably arranged inside the fixing member 58. Cover plates 510 are fixedly arranged on the outside of the number of rotating rods 59. Empty shells 511 are fixedly arranged at the positions corresponding to the number of rotating rods 59 inside the circular ring 56. A torsion spring 512 is arranged on the inside of the empty shell 511 close to the outside of the rotating rod 59.

[0031] The circular rod 52 is connected to the piston block 53 through a spherical ball. The piston block 53 and the vent pipe 54 are hermetically fitted. The vent pipe 54 is fixedly arranged inside the power head 1. The ventilation opening 55 communicates with the inside of the vent pipe 54. The number of rotating rods 59 and cover plates 510 are evenly arranged on the outside of the fixing member 58. The number of rotating rods 59 and the corresponding number of empty shells 511 are movably arranged. The two ends of the torsion spring 512 are respectively inserted into the inside of the empty shell 511 and the rotating rod 59.

[0032] Through the up and down movement of the four second rotating shafts 410, the four rotating rings 51 sleeved are respectively driven to move up and down, pulling or pushing the two circular rods 52 and piston blocks 53 to perform up and down piston movement in the two vent pipes 54. When the piston block 53 is pushed into the vent pipe 54 by the circular rod 52, the hot air generated in the cavity 3 enters the vent pipe 54 through the ventilation opening 55. The piston block 53 moving towards the inside of the vent pipe 54 accelerates the hot air to be discharged towards the side where the fixing frame 57 is arranged. When the air flow on one side impacts the cover plate 510, the greater pressure will push the cover plate 510 to drive the rotating rod 59 to rotate along the fixing member 58 and the empty shell 511 (as Figure 7 ), and at the same time tighten the torsion spring 512. Similarly, when pulling the piston block 53, it accelerates the entry of external air. The upper and lower two vent pipes 54 achieve one-in and one-out when the high-frequency vibration component 4 works, discharging the generated hot air inside. At the same time, the arrangement of multiple vent pipes 54 accelerates the circulation of the internal gas, improves the internal working environment, reduces the low efficiency caused by high temperature and ensures safety.

[0033] Working principle: When in use, the double-shaft motor 43 drives two groups of first rotating shafts 44 and the two groups of first bevel gears 45 connected thereto and the eccentric wheels 412 to rotate. The rotation of the two groups of first bevel gears 45 respectively drives the two groups of second bevel gears 411 engaged on both sides to rotate together. The two groups of second rotating shafts 410 simultaneously drive the two groups of eccentric wheels 412 connected thereto to rotate. By driving the four groups of eccentric wheels 412 to rotate together, the inertia generated by the rotating four groups of eccentric wheels 412 drives the double-shaft motor 43 and the two square bars 42 to slide up and down along the two fixed seats 41. The movement of the two square bars 42 respectively drives the top seats 46, the cross frame 48, and the vertical frame 49 to move together. The two top seats 46 move up and down and respectively squeeze the upper and lower return springs 47. Through the elasticity of the return springs 47, the vibration of reciprocating up and down movement is realized, and the generated vibration is transmitted to the drill bit. The use of multiple groups of eccentric wheels 412 provides stronger shock absorption function, more uniform and firm support, and a more stable and smooth experience compared with the traditional two-piece eccentric structure, and more effectively completes the high-frequency eccentric vibration acoustic wave work; in addition, through the up and down movement of the four groups of second rotating shafts 410, the four groups of rotating rings 51 sleeved thereon are respectively driven to move up and down, pulling or pushing the two round bars 52 and the piston block 53 to perform up and down piston movement in the two vent pipes 54. When the piston block 53 is pushed into the vent pipe 54 by the round bar 52, the hot air generated in the cavity 3 enters the vent pipe 54 through the vent hole 55. The piston block 53 moving towards the inside of the vent pipe 54 accelerates the hot air to be discharged towards the side provided with the fixed frame 57. When the airflow on one side impacts the cover plate 510, the greater pressure will push the cover plate 510 to drive the rotating rod 59 to rotate along the fixed member 58 and the empty shell 511 (as Figure 7 ), and at the same time tighten the torsion spring 512. Similarly, when pulling the piston block 53, it accelerates the entry of external air. The upper and lower two vent pipes 54 achieve one-in and one-out during the operation of the high-frequency vibration assembly 4, discharging the generated hot air sheets inside. At the same time, the setting of multiple vent pipes 54 accelerates the circulation of the internal gas, improves the internal working environment, reduces the low efficiency caused by high temperature, and ensures safety.
