Description

Technical Field

[0001] The invention relates to the technical field of drilling rig power heads, in particular to a high-frequency eccentric vibration sonic wave power head for a drilling rig. Background Art

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

[0007] Preferably, the two groups of the No. 1 bevel gears and the two groups of the No. 2 bevel gears are meshed with each other, and the horizontal frame and the vertical frame are cross-connected.

[0008] Preferably, the two groups of the second bevel gears and the first rotating shaft are both arranged on the inner sides of the horizontal frame and the vertical frame.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The dual-axis motor drives two sets of No. 1 rotating shafts and the two connected sets of No. 1 bevel gears and eccentric wheels to rotate, and the rotation of the two sets of No. 1 bevel gears respectively drives the two sets of No. 2 bevel gears meshing on both sides to rotate together, and the two sets of No. 2 rotating shafts simultaneously drive the two connected sets of eccentric wheels to rotate, and the four sets of eccentric wheels are driven to rotate together. The inertia generated by the rotating four sets of eccentric wheels drives the dual-axis motor and the two sets of square bars to slide up and down along the two sets of fixed seats, and the movement of the two sets of square bars drives the top seat, the horizontal frame and the vertical frame to move together respectively. The two sets of top seats move up and down, respectively squeezing the reset springs on the upper and lower sides, and the elasticity of the reset springs realizes the vibration of the up and down reciprocating motion, and the generated vibration is transmitted to the drill bit. The use of multiple sets of eccentric wheels provides stronger shock absorption function, more uniform and firm support, and more stable and smooth experience compared with the traditional two-piece eccentric structure, and more effectively completes the high-frequency eccentric vibration sound wave work.

[0013] 2. Through the up and down movement of the four groups of No. 2 rotating shafts, the four groups of sleeved rotating rings are driven to move up and down respectively, pulling or pushing the two groups of round rods and piston blocks to perform up and down piston movements in the two groups of ventilation pipes. When the piston blocks are pushed into the ventilation pipes by the round rods, the hot air generated in the cavity enters the ventilation pipes through the vents, and the piston blocks moving into the ventilation pipes accelerate and push the hot air to the side where the fixing frame is set. When the airflow on one side hits the cover plate, the greater pressure will push the cover plate to drive the rotating rod to rotate along the fixing piece and the empty shell (such as Figure 7 ), and tighten the torsion spring at the same time. Similarly, when the piston block is pulled, the outside air is accelerated to enter, and the upper and lower sets of ventilation pipes realize one in and one out in the high-frequency vibration component, and the hot air sheets generated inside are discharged. At the same time, the setting of multiple sets of ventilation pipes accelerates the circulation of internal gas, improves the internal working environment, reduces the low efficiency caused by high temperature, and ensures safety.

[0021] The cooling component 5 includes a rotating ring 51 rotatably arranged on the outside of two groups of rotating shafts No. 1 44 and No. 2 410, round rods 52 are fixedly arranged on the upper and lower ends of the rotating ring 51, piston blocks 53 are movably arranged on the upper and lower opposite sides of the two groups of round rods 52, ventilation pipes 54 are movably arranged on the outside of the two groups of piston blocks 53, and a plurality of ventilation ports 55 are opened on the two groups of ventilation pipes 54.

[0022] The round rod 52 is connected to the piston block 53 through a round ball. The piston block 53 and the ventilation pipe 54 are sealed and fitted. The ventilation pipe 54 is fixedly arranged inside the power head 1. The vent 55 is communicated with the inner side of the ventilation pipe 54. Several groups of rotating rods 59 and cover plates 510 are evenly arranged on the outside of the fixing part 58. Several groups of rotating rods 59 and corresponding groups of empty shells 511 are movably arranged. The two ends of the torsion spring 512 are respectively inserted into the empty shell 511 and the rotating rod 59.

[0024] Working principle: When in use, the two sets of No. 1 rotating shafts 44 and the two connected sets of No. 1 bevel gears 45 and eccentric wheels 412 are driven to rotate by the double-axis motor 43, and the rotation of the two sets of No. 1 bevel gears 45 respectively drives the two sets of No. 2 bevel gears 411 meshing on both sides to rotate together, and the two sets of No. 2 rotating shafts 410 simultaneously drive the two connected sets of eccentric wheels 412 to rotate, and the four sets of eccentric wheels 412 are driven to rotate together, and the inertia generated by the rotating four sets of eccentric wheels 412 drives the double-axis motor 43 and the two sets of square bars 42 to slide up and down along the two sets of fixed seats 41, and the movement of the two sets of square bars 42 drives the top seat 46, the horizontal frame 48, and the vertical frame 49 to move together, and the two sets of top seats 46 move up and down, respectively squeezing the reset springs 47 on the upper and lower sides, and the elasticity of the reset springs 47 realizes the vibration of the up and down reciprocating motion, and the generated vibration is transmitted to the drill bit, using The use of multiple sets of eccentric wheels 412 provides a stronger shock absorption function, a more uniform and firm support, and a more stable and smooth experience compared to the traditional two-piece eccentric structure, and more effectively completes the high-frequency eccentric vibration sound wave work; in addition, through the up and down movement of the four sets of second rotating shafts 410, the four sets of sleeved rotating rings 51 are driven to move up and down respectively, pulling or pushing the two sets of round rods 52 and piston blocks 53 to perform up and down piston movements in the two sets of ventilation pipes 54. When the piston block 53 is pushed into the ventilation pipe 54 by the round rod 52, the hot air generated in the cavity 3 enters the ventilation pipe 54 through the vent 55, and the piston block 53 moving into the ventilation pipe 54 accelerates and pushes the hot air to the side where the fixing frame 57 is provided. When the airflow on one side hits 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 (such as Figure 7 ), and tighten the torsion spring 512 at the same time. Similarly, when the piston block 53 is pulled, the outside air is accelerated to enter, and the upper and lower groups of ventilation pipes 54 work in the high-frequency vibration component 4 to realize one in and one out, and the hot air sheets generated inside are discharged. At the same time, the setting of multiple groups of ventilation pipes 54 accelerates the circulation of internal gas, improves the internal working environment, reduces the low efficiency caused by high temperature, and ensures safety.
