Technical Field
[0001] This utility model relates to the field of drilling rig technology, specifically to an integrated machine of steering and transmission housing and mechanical top drive drilling rig and full hydraulic drilling rig that is suitable for various geological and engineering borehole exploration as well as water well drilling. Background Technology
[0002] Currently, fully hydraulic drilling rigs are widely used in geological exploration tasks due to their stable operation and ease of use. However, when facing deep-hole geological exploration, fully hydraulic drilling rigs, due to insufficient rotational torque, pose risks, easily leading to accidents such as stuck drill bits and drill bit burial, resulting in significant losses. Using mechanical top-drive drilling rigs entirely for deep-hole geological exploration is less efficient than using fully hydraulic drilling rigs. Therefore, to prevent stuck drill bits and drill bit burial accidents, it is necessary to increase the power of fully hydraulic drilling rigs, thus increasing the cost of shallow-hole drilling. Furthermore, if a stuck drill bit or drill bit burial accident occurs with a fully hydraulic drilling rig, replacing it with another mechanical top-drive drilling rig to handle the accident and continue drilling is extremely difficult and costly.

Compared with the combined manufacturing costs of the two types of drilling rigs mentioned above, the manufacturing cost of this utility model is significantly reduced. Using this utility model for deep-hole geological exploration is safe, reliable, and low-cost. The steering box utilizes the rotational support of the first support shaft to achieve steering. During the rotation of the steering box, it drives the internal second transmission shaft to revolve around the first support shaft. Simultaneously, the second transmission shaft maintains its self-rotation during this revolution using the drive of the first transmission shaft, thus realizing the steering and transmission functions of the steering and transmission box. This allows the steering and transmission box to output mechanical power in different directions. The steering and transmission housing on the drilling rig allows for mechanical power input to the mast within a certain tilt angle range. This means that mechanical power is generated from the prime mover, transmitted through the gearbox, third universal joint coupling, transfer case, reversing box, first universal joint coupling, steering, transmission housing, and hexagonal transmission rod, and then to the integrated power head. This provides the hardware foundation for combining mechanical and hydraulic drilling rigs. The integrated power head possesses both hydraulic and mechanical power, allowing for the selection of the required driving force for the drill rod during drilling operations, based on the actual needs of the drilling work. This enables efficient and safe completion of deep-hole geological exploration operations. The operation of the first and second shift hydraulic cylinders facilitates easy switching between hydraulic and mechanical power for the drill rod driving force, thereby improving drilling efficiency.

Detailed Implementation
[0025] The following will describe specific embodiments and appendices. Figure 1-8 The technical solutions in the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some preferred embodiments of this utility model, and not all embodiments. Those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0026] This utility model provides a steering and transmission housing 1 (such as...) Figure 4 , Figure 5 As shown, the steering housing 11 includes a steering box 11, a first power input end 12, a first power output end 13, and a first transmission assembly. Two first support shafts 111 are symmetrically arranged at the lower part of the steering box 11. In practical applications, the corresponding ends of the first support shafts 111 are flange-shaped, and these flange-shaped ends are fixed to the steering box 11 by bolt connection. Utilizing the rotational support of the two first support shafts 111, the steering box 11 can rotate circumferentially around the axis of the first support shafts 111. The input end 12 is rotatably disposed at the lower part of the steering housing 11, and the axis of rotation of the first power input end 12 relative to the steering housing 11 is coaxially distributed with the axis of rotation of the first support shaft 111. Because the first power input end 12 is rotatably disposed relative to the steering housing 11 and the axis of rotation is coaxially distributed with the axis of rotation of the steering housing 11, the first power input end 12 can remain stationary when the steering housing 11 rotates around the first support shaft 111. Therefore, in practical applications, this feature can be used to adjust the angle of the steering housing 11 or the angle of rotation of the steering housing 11. During the adjustment process, driving force is continuously input to the first power input end 12. The first power output end 13 is vertically arranged on the upper left side of the steering box 11. With the above design, the angle of the first power input end 12 relative to the steering box 11 and the position of the first power output end 13 are not fixed. Thus, while maintaining a stable power input to the first power input end 12, the angle of the first power output end 13 can be changed according to actual needs to achieve variable angle power output. The first transmission component is arranged in the steering box 11, and the power of the first power input end 12 can be transmitted to the first power output end 13 through the first transmission component in the steering and transmission box 1. After the steering box 11 is rotated and adjusted, the direction of the first power output end 13 is adjusted. The adjustability of the direction of the first power output end 13 can meet the continuous power input of the actuator with angle changes. For example, in the existing drilling rig, the mast direction can be adjusted according to needs. After the mast is adjusted, the steering and transmission box 1 can still meet the power needs of some actuators located on the mast.
[0027] Based on the above embodiments, the specific implementation of the first transmission assembly within the steering and transmission housing 1 is as follows: The first transmission assembly includes a first transmission shaft 141 and a second transmission shaft 142. The first transmission shaft 141 is rotatably disposed at the lower part of the steering housing 11 and coaxially distributed between two first support shafts 111. Specifically, both ends of the first transmission shaft 141 are fitted into two corresponding tapered roller bearings disposed within the steering housing 11. The second transmission shaft 142 is rotatably disposed on the upper side inside the steering housing 11. Specifically, both ends of the second transmission shaft 142 are fitted into two corresponding tapered roller bearings disposed within the steering housing 11. The first transmission shaft 141 and the second transmission shaft 142 achieve transmission through a gear set. The gear set includes a fifth transmission gear 1411, a seventh transmission gear 143, and a sixth transmission gear 1421. The fifth transmission gear 1411 is keyed to the right end of the first transmission shaft 141. The seventh transmission gear 143 is mounted on a support shaft mounted on the steering housing 11. Specifically, several deep groove ball bearings are mounted on the support shaft. The first transmission gear 143 is mounted on the outer ring of the deep groove ball bearings. The sixth transmission gear 1421 is keyed to the right end of the second transmission shaft 142. The seventh transmission gear 143 meshes with the fifth transmission gear 1411 and the sixth transmission gear 1421. When the first transmission shaft 141 rotates, the second transmission shaft 142 is ultimately rotated.
[0028] Based on the above embodiments, the specific implementation of the first power input terminal 12 and the second power output terminal 13 is as follows: The first power input terminal 12 includes a first housing 121, a third drive shaft 122, and a first bevel gear 123. The first housing 121 is rotatably sleeved on the first drive shaft 141. Utilizing the rotational characteristic of the first drive shaft 141 relative to the steering housing 11, the first housing 121 can remain stationary when the steering housing 11 rotates. The third drive shaft 122 is rotatably disposed within the first housing 121, and the first bevel gear 123 is disposed on the third drive shaft 121. Specifically, the first bevel tooth 123 can be fixedly sleeved on the upper part of the third transmission shaft 122 by key transmission, or the first bevel tooth 123 and the third transmission shaft 122 can be directly machined as an integral part; a second bevel tooth 1412 that meshes with the first bevel tooth 123 is fixedly provided on the first transmission shaft 141; when the third transmission shaft 122 rotates, the rotation of the second bevel tooth 1412 is realized through the first bevel tooth 123, and the rotation of the second bevel tooth 1412 realizes the rotation of the first transmission shaft 141. During the rotation of the steering box 11, the seventh transmission... While rotating on its own axis, gear 143 revolves around the fifth transmission gear 1411, thus ensuring a continuous driving force for the second transmission shaft 142 during the rotation of the steering housing 11. The first power output end includes a second housing 131, a fourth transmission shaft 132, and a third bevel gear 133. The second housing 131 is fixedly connected to the steering housing 11. Specifically, the second housing 131 can be fixed to the steering housing 11 by bolts or cast as a single piece. The fourth transmission shaft 132 is rotatably mounted on... On the second housing 131, the third bevel tooth 133 is fixedly disposed on the lower part of the fourth transmission shaft 132. Specifically, the third bevel tooth 133 can be fixedly sleeved on the upper part of the fourth transmission shaft 132 by key transmission, or the third bevel tooth 133 and the fourth transmission shaft 132 can be directly machined as an integral part. A fourth bevel tooth 1422 that meshes with the third bevel tooth 133 is fixedly disposed on the second transmission shaft 142. During the continuous rotation of the second transmission shaft 142, the continuous rotation of the fourth transmission shaft 132 is achieved by driving the fourth bevel tooth 1422.

Figure 1As shown), it includes a shared tracked chassis 2, a power output assembly, a mast 3, and a mast lifting cylinder 4. The shared tracked chassis 2 is actually a tracked chassis in the existing technical field. In this specific embodiment, it is named a shared tracked chassis 2 only to emphasize that it can provide joint support for the actuators related to the hydraulic power part and the mechanical power part in the integrated machine. Therefore, the detailed structure and working principle of the shared tracked chassis 2 will not be described in detail here. The power output assembly is set on the shared tracked chassis 2. The integrated mechanical top drive drilling rig and the fully hydraulic drilling rig also includes a hexagonal transmission rod 31 and an integrated power head 5. At the same time, the integrated mechanical top drive drilling rig and the fully hydraulic drilling rig also includes the steering and transmission housing 1 mentioned above. The two first support shafts 111 are arranged in a rotatable manner relative to each other on the shared tracked chassis 2. Specifically, on the upper right side of the common tracked chassis 2, two mounting seats 26 are provided. The corresponding ends of the first support shaft 111 are mounted on the corresponding mounting seats 16 through sliding bearing seats with sliding bearings. The sliding bearings support the first support shaft 111, enabling the free rotation of the first support shaft 111, and thus enabling the steering box 11 to rotate freely relative to the common tracked chassis 2. The upper part of the steering box 11 is fixedly sleeved on the lower inner side of the mast 3. With the support of the steering box 11, the mast 3 can make circular motion along the axis of the first support shaft 111. In practical applications, the tilt angle of the mast 3 can be adjusted. Specifically, the mast 3 can be arbitrarily positioned within the range of 0-90° relative to the ground, and the steering box 11 can transmit mechanical power to meet all drilling requirements.The fourth drive shaft 132 is distributed along the length of the mast 3, and its outer end is located between the upper part of the mast 3 and the steering box 11. One end of the hexagonal drive rod 31 is rotatably mounted on the upper part of the mast 3, and the other end of the hexagonal drive rod 31 is connected to the outer end of the fourth drive shaft 132. Specifically, a bearing seat is provided on the mast 3, a drive shaft is fitted inside the bearing seat, a flange is provided at both ends of the drive shaft, a flange is provided at the lower part of the hexagonal rod 31, and a flange is provided at the outer end of the fourth drive shaft 132. The flanges at both ends of the drive shaft are connected to the corresponding flanges. Then, the fourth drive shaft 132 and the hexagonal drive rod 31 are connected. When the fourth drive shaft 132 rotates, it synchronously drives the hexagonal drive rod 31 to rotate. The fixed end of the mast lifting cylinder 4 is hinged to the common track chassis 2. The telescopic end of the mast lifting cylinder 4 is hinged to the upper left side of the mast 3. By utilizing the telescopic movement of the mast lifting cylinder 4, the mast 3 can be freely rotated around the first support shaft 111, thereby realizing the angle adjustment and positioning of the mast 3. The integrated power head 5 includes an integrated housing 51, a hydraulic drive assembly 53, a drill pipe connection assembly 52, and a mechanical drive assembly 54. 4. The hydraulic drive assembly 53, drill pipe connection assembly 52, and mechanical drive assembly 54 are all mounted on the integrated housing 51. The integrated housing 51 is mounted on the mast 3 and can slide and be positioned freely on the mast 3. Specifically, the integrated housing 51 is slidably fitted onto a track on the mast 3. Two feed cylinders 32 are mounted on the mast 3. The fixed end of the feed cylinder 32 is located on the upper part of the mast 3, and the movable end of the feed cylinder 32 is connected to the integrated housing 51. The sliding and positioning of the integrated power head 5 on the mast 3 is achieved by the extension and retraction movement of the two feed cylinders 32. The hydraulic drive assembly... Hydraulic drive assembly 53 and mechanical drive assembly 54 can switch between each other to independently provide rotational power to drill pipe connection assembly 52. That is, when hydraulic drive assembly 53 provides power to drill pipe connection assembly 52, mechanical drive assembly 54 does not provide power to drill pipe connection assembly 52; conversely, when mechanical drive assembly 54 provides power to drill pipe connection assembly 52, hydraulic drive assembly 53 does not provide power to drill pipe connection assembly 52. The power output assembly can provide power to mast lifting cylinder 4, third drive shaft 122, and hydraulic drive assembly 53, while the hexagonal transmission rod 31 can provide power to mechanical drive assembly 54.

The telescopic end of the first shift hydraulic cylinder 5341 is hinged to the outer end of the first swing arm 5342. The lower part of the first shift fork 5344 is sleeved between the low-speed transmission gear 5332 and the high-speed transmission gear 5331, and the first shift fork 5344 is distributed in the radial plane of the fifth transmission shaft 532. The upper part of the first shift fork 5344 is fixedly connected to the first shift fork swing drive shaft 5343. When the first shift hydraulic cylinder 5341 performs telescopic movement, it drives the first swing arm 5342 to rotate.The rotation of the first swing arm 5342 drives the lower part of the first shift fork 5344 to reciprocate. During the reciprocating motion of the lower part of the first shift fork 5344, the low-speed transmission gear 5332 and the high-speed transmission gear 5331 reciprocate along the axial direction of the fifth transmission shaft 532. After setting the extension and retraction stroke of the first shift hydraulic cylinder 5341, the second transmission gear set can be switched between low-speed, neutral, and high-speed working positions, thereby realizing the hydraulic speed change drive of the hollow drill rod connecting shaft 521.
[0032] Based on the above embodiments, the specific implementation of the mechanical drive assembly 54 is as follows: The mechanical drive assembly 54 includes a sixth drive shaft 541, a third drive gear 542, a seventh drive shaft 543, a fourth drive gear 544, and a second shifting operating mechanism. The sixth drive shaft 541 is rotatably disposed within the integrated housing 51. Specifically, both ends of the sixth drive shaft 541 are fitted into two corresponding tapered roller bearings disposed within the integrated housing 51, and the free rotation of the sixth drive shaft 541 is achieved by the support of the tapered roller bearings. The hexagonal drive rod 31 is fitted into a hexagonal through hole within the sixth drive shaft 541, and the rotation of the hexagonal drive rod 31 drives the rotation of the sixth drive shaft 541. The third drive gear 542 is fitted outside the sixth drive shaft 541, and the rotation of the sixth drive shaft 541 drives the synchronous rotation of the third drive gear 542. The seventh drive shaft 543 is rotatably fitted into the integrated housing 51. Specifically, on the integrated housing 51, both ends of the seventh drive shaft 543 are fitted into two corresponding deep groove ball bearings inside the integrated housing 51. The support of the deep groove ball bearings enables the free rotation of the seventh drive shaft 543. The fourth drive gear 544 is fitted onto the seventh drive shaft 543 using a spline transmission method. The fourth drive gear 544 can slide on the seventh drive shaft 543. The second shifting operation mechanism can realize the synchronous engagement or disengagement of the fourth drive gear 544 with the second drive gear 523 and the third drive gear 542. When the fourth drive gear 544 is synchronously engaged with the second drive gear 523 and the third drive gear 542, the hollow drill rod connecting shaft 521 is driven, thereby realizing the mechanical power to drive the drill rod to rotate. When the fourth drive gear 544 is synchronously disengaged from the second drive gear 523 and the third drive gear 542, the mechanical power to drive the drill rod is released.Further, the second shifting operating mechanism includes a second shifting hydraulic cylinder 5451, a second swing arm 5452, a second shift fork swing drive shaft 5453, and a second shift fork 5454. The second shift fork swing drive shaft 5453 is rotatably disposed within the integrated housing 51 and located above the seventh transmission shaft 543. The axis of the second shift fork swing drive shaft 5453 is perpendicular to the axis of the seventh transmission shaft 543. The second swing arm 5452 is fixedly connected to one end of the second shift fork swing drive shaft 5453. The fixed end of the second shifting hydraulic cylinder 5451 is hinged to the outside of the integrated housing 51. The telescopic end of the second shifting hydraulic cylinder 5451 is hinged to the outer end of the second swing arm 5452. The lower part of the second shift fork 5454 is sleeved on the annular recess of the fourth transmission gear 544. The second shift fork 5454 is located within the groove and distributed within the radial surface of the seventh transmission shaft 543. The upper part of the second shift fork 5454 is fixedly connected to the second shift fork swing drive shaft 5453. When the second shift hydraulic cylinder 5451 extends or retracts, it drives the second swing arm 5452 to rotate. The rotation of the second swing arm 5452 drives the lower part of the second shift fork 5454 to reciprocate. During the reciprocating swing of the lower part of the second shift fork 5454, the fourth transmission gear 544 is driven to reciprocate along the axial direction of the seventh transmission shaft 543. After setting the extension and retraction stroke of the second shift hydraulic cylinder 5451, the fourth transmission gear 544 can be synchronously engaged or disengaged with the second transmission gear 523 and the third transmission gear 542, thereby realizing the input or cutoff of mechanical driving force on the hollow drill pipe connecting shaft 521. In practical applications, because the mechanical driving torque obtained by the hollow drill pipe connecting shaft 521 is very large, this device can also be used for water well drilling operations.
[0033] Based on the above embodiments, the power output assembly includes a prime mover 21, a gearbox 22, a transfer case 23, a reversing gearbox 24, and an oil pump 25. The prime mover 21, gearbox 22, transfer case 23, reversing gearbox 24, and oil pump 25 are all known mature technologies in the mechanical field; therefore, the specific working principles and structures of the prime mover 21, gearbox 22, transfer case 23, reversing gearbox 24, and oil pump 25 will not be described in detail. The prime mover 21 can be a gasoline engine, a diesel engine, or a gas engine. In this specific embodiment, a diesel engine is selected as the prime mover 21. The prime mover 21 is mounted on the common tracked chassis 2. The oil pump 25 is connected to the left side of the prime mover 21. Specifically, the oil pump 25 achieves a transmission connection with the corresponding power output end of the prime mover 21 through a second universal joint coupling 251. The gearbox 22 is connected to the right side of the prime mover 21. The transfer case 23 is mounted on the... On the right side of the gearbox 22, specifically, the transfer case 23 is connected to the power output end of the gearbox 22 via a third universal joint coupling 232. A shift lever 231 is provided on the transfer case 23. The reversing box 24 is located on the right side of the transfer case 23. The power output end of the reversing box 24 is connected to the third drive shaft 122. Specifically, the power output end of the reversing box 24 is connected to the third drive shaft 122 via a first universal joint coupling 241. Through the above design, mechanical power is generated from the prime mover 21, and transmitted to the integrated power head 5 via the gearbox 22, the third universal joint coupling 232, the transfer case 23, the reversing box 24, the first universal joint coupling 241, the steering, the transmission housing 1, and the hexagonal transmission rod 31. In actual application, the power transmission and disconnection between the transfer case 23 and the reversing box 24 can be achieved by operating the shift lever 231 on the transfer case 23. The oil pump 25 delivers or cuts off the power hydraulic oil to the mast lifting cylinder 4 and the hydraulic motor 531 through the corresponding hydraulic system pipeline, and uses the relevant hydraulic control valves in the hydraulic system pipeline to switch the mast lifting cylinder 4 and the hydraulic motor 531 to rotate forward or in reverse.
[0034] In practical applications, the support on the shared tracked chassis 2 is equipped with outrigger cylinders around its perimeter. During drilling operations, the bottom of the outrigger cylinders contacts the ground. When the drill rod is rotated for drilling operations using the support of the mast 3, a hydraulic ground contact device is installed at the bottom of the mast 3 to improve the stability of the mast 3. When it contacts the ground, it can reduce the vibration of the mast during drilling operations and increase the stability of the drilling rig.
[0035] The process of using the integrated machine of this utility model for deep hole exploration is as follows: First, operate the outrigger cylinder to touch the ground, operate the gearbox 22 to disengage the clutch, and move the shift lever 231 of the transfer case 23 to the neutral position to cut off the mechanical power; use the second shift hydraulic cylinder 5451 to synchronously disengage the fourth transmission gear 544 from the second transmission gear 523 and the third transmission gear 542, reducing the rotational resistance for the hydraulic motor 531 to drive the drill rod to rotate; then, according to the construction requirements, operate the mast lifting cylinder 4 to make the mast 3 tilt to the required angle for the exploration hole; then operate the lower end ground contact device of the mast 3 to touch the ground; activate the hydraulic motor 531 to input the hydraulic driving force for the drill rod; then, operate the feed cylinder 32 to drive the integrated power head 5 to move, thereby realizing the drilling rod... During drilling or hoisting operations, when it is necessary to apply mechanical driving force to the drill rod to increase its torque, the hydraulic driving force of the drill rod is cut off by operating the first shift hydraulic cylinder 5341. Then, the clutch of the gearbox 22 is disengaged, and the shift lever 231 of the transfer case 23 is moved to the right position, thereby realizing the transmission of mechanical power to the reversing box 24. The power of the reversing box 24 is then transmitted to the sixth drive shaft 541. The fourth transmission gear 544 is synchronously engaged with the second transmission gear 523 and the third transmission gear 542 by the second shift hydraulic cylinder 5451, thereby finally realizing the input of mechanical power to the drill rod. Further drilling operations can then be carried out based on the previous drilling depth, thus completing the deep hole exploration operation.
