Description
Technical Field
[0001] This utility model belongs to the field of mining drilling rigs and relates to an asynchronous rotation device for adjusting the inclination angle of a drilling rig. Background Technology
[0002] Against the backdrop of the intelligent development strategy for coal mines, drilling automation has become a key means to promote the transformation of underground operations towards less manned and unmanned operations. In traditional coal mining operations, drilling rig operation mainly relies on manual labor. However, the underground working environment is extremely complex, with many uncertainties, such as potential dangers like gas and coal dust. At the same time, workers are under high-intensity, high-risk working conditions for extended periods, making them highly susceptible to fatigue. This traditional manual operation mode, limited by both the complex underground environment and worker fatigue, cannot simultaneously meet the dual demands of efficient modern coal mining and ensuring inherent safety. On the one hand, manual operation has limited efficiency, making it difficult to achieve rapid and precise drilling operations, thus hindering the improvement of coal mining efficiency. On the other hand, workers operating in complex and dangerous environments face high safety risks; the consequences of an accident would be unimaginable.
[0003] The emergence of automation technology has provided an effective way to solve the above problems. By applying automation technology, the drilling process and related auxiliary procedures of drilling rigs can be automated. This not only significantly reduces the labor intensity of operators and the time personnel are exposed to dangerous areas, thus greatly improving operational safety, but also breaks through the efficiency bottleneck of manual operation, making coal mining operations more efficient and stable. Therefore, automated drilling rig technology has become an inevitable choice for technological upgrading in the coal industry. After nearly ten years of development, automated drilling rig technology has made great strides and become increasingly mature. Currently, automated drilling rigs can achieve fully automated operation of key processes such as loading and unloading drill rods, drilling, and attitude adjustment, and have been widely applied in coal mine disaster prevention projects such as gas drainage and water exploration, providing strong guarantees for safe coal mine production.
[0004] However, existing automatic drilling rig technology still has some problems that urgently need to be solved. Taking a certain automatic drilling rig used in the industry (application number: CN201911185745.9) as an example, the inclination angle design of its drill pipe transfer device is flawed. It cannot be adjusted according to changes in the frame inclination angle and can only rely entirely on the drill pipe conveying robot to adjust the drill pipe conveying inclination angle. More importantly, the layout of the drill pipe transfer device and drill pipe conveying robot with the frame in the existing technology is unreasonable. The drill pipe transfer device and drill pipe conveying robot are arranged on the same side of the lifting sleeve (named "lifting frame" in CN201911185745.9), while the frame is located on the other side of the lifting sleeve. Moreover, the transfer device and robot are located on the side closer to the tracked vehicle. This inevitably causes interference between the drill pipe conveying robot, the tracked vehicle, and the drill pipe transfer device during the inclination angle adjustment process, especially under negative inclination angle conditions. This technical challenge prevents existing automatic drilling rigs from drilling at large negative inclination angles, which to some extent limits the advancement of comprehensive intelligent construction in coal mines and also restricts the application of automated drilling rig technology in a wider range of scenarios. Utility Model Content
[0005] In view of this, the purpose of this utility model is to provide an asynchronous rotation device for adjusting the inclination angle of a drilling rig, so as to solve the problem that the drill rod transfer device cannot adjust the inclination angle along with the frame, resulting in a small drilling inclination angle range of the drilling rig.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] An asynchronous rotating device for adjusting the inclination angle of a drilling rig, comprising:
[0008] The lifting sleeve serves as the carrier for the asynchronous rotation device;
[0009] A lifting cylinder is used to vertically lift and lower the lifting sleeve onto the rotary platform of the drilling rig;
[0010] The rotary actuator, mounted on the lifting sleeve, is configured to adjust the inclination angle of the drill pipe rotary actuator; and
[0011] An angle rotator is mounted on the lifting sleeve and is located on the same side of the lifting sleeve as the transfer device rotator, and is configured to adjust the angle of the frame;
[0012] The rotary transferor and the tilting rotary transferor can be operated independently to adjust the tilting angle of the drill pipe transferor and the frame, respectively.
[0013] Furthermore, the lifting sleeve includes:
[0014] The lifting cavity is formed by two front and rear side plates and a top sealing plate, and is configured to accommodate the lifting cylinder;
[0015] Sleeves, fixedly installed on the left and right sides of the lifting sleeve cavity, serve as guides for movement along the lifting column; and
[0016] The connecting cylinder is fixedly installed on the side of the lifting sleeve cavity facing the frame, and has a flange for installing the rotary transition plate.
[0017] Furthermore, the rotary transition plate is disk-shaped and includes:
[0018] The first transition plate flange is configured to connect to the connecting cylinder;
[0019] The second transition plate flange is configured to connect to the frame connection plate; and
[0020] The third transition plate flange is configured to connect to the rotary unit of the transfer device.
[0021] Furthermore, the transferor rotary includes:
[0022] A retaining ring is connected to the third transition plate flange of the rotary transition plate; and
[0023] The rotating ring is connected to the drill pipe transfer device, and its inclination angle is adjusted.
[0024] Furthermore, the frame connecting plate is disc-shaped and includes:
[0025] A first flange, configured to connect to a second transition plate flange of the rotary transition plate; and
[0026] The second flange is configured to connect to the tilt slewing device.
[0027] Furthermore, the tilt gyroscope includes:
[0028] A retaining ring is connected to the second flange of the frame connecting plate; and
[0029] The rotating ring is fixedly connected to the frame and configured to adjust the tilt angle of the frame.
[0030] Furthermore, the retaining ring of the transferor rotator is directly installed on the lifting sleeve, and the retaining ring of the tilting rotator is installed on the retaining ring of the transferor rotator.
[0031] Furthermore, the retaining ring of the tilting rotator is directly installed on the lifting sleeve, and the retaining ring of the transfer device rotator is installed on the retaining ring of the tilting rotator.
[0032] The beneficial effects of this invention are as follows:
[0033] 1. This technical solution overcomes the limitation of traditional drilling rigs where the drill rod transferor's tilt angle cannot be adjusted or can only be adjusted synchronously with the frame tilt angle by fixing the two rotary devices (transferor rotary device and tilt angle rotary device) that drive the drill rod transferor and the frame tilt angle to the same side of the lifting sleeve. Traditional drilling rigs, due to the synchronous adjustment of the drill rod transferor and the frame, limit the drilling tilt angle range. This solution introduces an asynchronous rotation device, allowing the tilt angles of the drill rod transferor and the frame to be adjusted independently. As a result, the drilling tilt angle range is extended to the entire circumference, significantly improving the drilling rig's flexibility and adapting to more complex drilling needs.
[0034] 2. In the confined space between the frame and the lifting sleeve, traditional designs struggle to achieve independent control of the drill pipe transfer device and the frame tilt angle. This technical solution cleverly utilizes two disc-shaped transition components—a rotary transition plate and a frame connecting plate—to place the two rotary devices on the same side of the lifting sleeve, optimizing the spatial layout. The transfer device rotary device and the tilt angle rotary device operate independently via a fixed ring and a rotating ring, respectively, ensuring that the tilt angle adjustment of the drill pipe transfer device (i.e., the drill pipe to be transferred) and the frame does not interfere with each other. This design not only improves space utilization efficiency but also allows operators to flexibly adjust the angle according to actual needs, enhancing drilling accuracy and operational convenience.
[0035] 3. This technical solution significantly enhances the practicality and adaptability of automatic drilling rigs. Traditional drilling rigs, due to the inability of the drill pipe transfer device to adjust its inclination angle independently of the frame, struggle to cope with varying geological conditions. This solution, however, utilizes an asynchronous adjustment mechanism, allowing the drill pipe transfer device's inclination angle to be adjusted within a wide range, covering the entire circumference of the borehole. This breakthrough provides drilling operations with greater operational space and higher precision, meeting the demands of modern drilling for high efficiency and flexibility, and effectively improving operational efficiency and quality.

[0045] Example 1
[0046] Please see Figures 1-3This is an asynchronous rotating device for adjusting the tilt angle of a drilling rig, comprising a lifting sleeve 705, a transferor rotator 709, a tilt angle rotator 710, a rotatable transition plate 712, and a frame connecting plate 713. The specific structures of each component are as follows:
[0047] 1. Lifting sleeve 705
[0048] like Figure 3 As shown, the lifting sleeve 705 is a connecting part for components such as the transfer device and the rotary device in the attitude adjustment device, including the lifting sleeve cavity 70501, the sleeve 70502 and the connecting sleeve 70503.
[0049] The lifting sleeve cavity 70501 is formed by two front and rear side plates and a top sealing plate. The lifting sleeve cavity 70501 is used to install the lifting cylinder 706. One end of the lifting cylinder 706 is connected to the lifting sleeve cavity 70501 by means of a pin, etc., and the other end is fixedly installed on the rotary platform 702, thereby driving the lifting sleeve 705 to move up and down along the lifting column 704.
[0050] Specifically, the rotary platform 702 is rotatably mounted on the moving platform of the drilling rig via the azimuth rotator 701, so that the asynchronous rotating device is arranged on the drilling rig.
[0051] The sleeve 70502 is fixedly installed on the left and right sides of the lifting sleeve cavity 70501 and serves as a guide for the lifting sleeve 705 to move up and down along the lifting column 704.
[0052] The connecting cylinder 70503 is fixedly installed on the side of the lifting sleeve cavity 70501 facing the frame 11, and is provided with a flange for installing the rotary transition plate 712.
[0053] 2. Rotary transition plate 712
[0054] The rotary transition plate 712 is a disc-shaped part with three sets of flanges arranged from the inside out: a first transition plate flange, a second transition plate flange, and a third transition plate flange. The innermost first transition plate flange matches the flange of the connecting cylinder 70503, fixing itself to the lifting sleeve 705; the two outermost flanges are used to install the transfer device rotary device 709 and the frame connecting plate 713, respectively.
[0055] Specifically, the transferor rotary 709 is installed on the side of the rotary transition plate 712 near the lifting sleeve 705 and is connected to the third transition plate flange, while the frame connecting plate 713 is installed on the side of the rotary transition plate 712 away from the lifting sleeve 705 and is connected to the second transition plate flange.
[0056] 3. Transfer device rotary 709
[0057] The rotary transducer 709 is a drive element used to adjust the drill pipe transducer (which is mounted on top of the rotary transducer 709).
[0058] The fixed ring (preferably the outer ring in this application) of the rotary transferor 709 is bolted to the third transition plate flange of the rotary transition plate 712, thereby indirectly fixing it to the lifting sleeve. Preferably, the inner ring is a rotating ring and is fixedly connected to the outer shell of the rotary transferor 709. The drill pipe transferor is fixedly installed on the top of the outer shell of the rotary transferor 709, allowing the tilt angle to be adjusted as the outer shell rotates. The rotary transferor 709 is preferably a worm gear reducer.
[0059] 4. Frame connection plate 713
[0060] The frame connecting plate 713 is a disc-shaped part with two sets of flanges, which are used to connect with the second transition plate flange of the rotary transition plate 712 and the tilting rotary device 710, respectively.
[0061] 5. Tilt Rotary Gear 710
[0062] The principle of the tilting rotator 710 is the same as that of the transfer rotator 709. Similarly, the fixing ring is preferably the outer ring, connected to one set of flange bolts on the frame connecting plate 713, thereby indirectly fixing it to the lifting sleeve 705; the rotating ring is the inner ring, and is fixedly connected to the frame 11 to drive the frame 11 to rotate circumferentially. Specifically, the frame 11 is arranged on the side of the tilting rotator 710 away from the lifting sleeve 705.
[0063] The working principle of this embodiment is as follows:
[0064] The fixed ring of the rotary transferor 709 is bolted to the third transition plate flange of the rotary transition plate 712, thereby indirectly fixing it to the lifting sleeve. The rotating ring of the rotary transferor 709 is fixedly connected to the drill pipe transferor to adjust the inclination angle of the drill pipe transferor.
[0065] The frame connecting plate 713 is fixedly installed on the rotary transition plate 712, thereby indirectly fixed to the lifting sleeve. The rotating ring of the tilting rotator 710 is connected to the frame 11, and the fixing ring of the tilting rotator 710 is fixedly installed on the frame connecting plate 713, thereby indirectly fixed to the lifting sleeve.
[0066] Therefore, the fixed rings of the transferor rotary 709 and the tilt angle rotary 710 are both fixedly installed on the lifting sleeve 705, while the rotating rings respectively carry the drill pipe transferor and the frame, and are not restricted by the lifting sleeve to rotate, and can rotate independently and freely, thus forming an asynchronous rotating transpose that drives the frame and the drill pipe transferor to adjust their tilt angles separately, thereby allowing the tilt angles of the frame and the drill pipe transferor to be adjusted independently.
[0067] Through two disc-shaped transition parts, the rotary transition plate and the frame connecting plate, the rotary 709 and the tilt 710 that drive the drill rod transfer device and the frame tilt rotation are respectively fixed on the same side of the lifting sleeve. In the narrow space between the frame and the lifting sleeve, the tilt angle of the drill rod transfer device can be adjusted independently of the frame, so that the tilt angle of the drill rod transfer device (i.e. the drill rod to be transported) can be adjusted within a wide range along with the frame, which helps to expand the drilling tilt angle range of the automatic drilling machine to the entire circumference.
[0068] In operation, the transferor rotator 709 and the tilt rotator 710 can be independently controlled by their respective motors (or hydraulic motors). The operator can adjust the tilt angle of the drill pipe transferor or the tilt angle of the frame 11 individually according to drilling requirements. For example, when adjusting the angle of the drill pipe transferor, only the transferor rotator 709 needs to be activated, while the angle of the frame 11 remains unchanged; conversely, the angle can be adjusted as needed. This asynchronous adjustment design improves the flexibility of the drilling rig. Alternatively, the transferor rotator 709 and the tilt rotator 710 can be activated simultaneously to synchronously adjust the tilt angle of the drill pipe transferor and the tilt angle of the frame 11, making them the same or different tilt angles.
[0069] Example 2
[0070] This embodiment provides an alternative asynchronous rotation device, also used for drilling rig tilt adjustment. Unlike Embodiment 1, the installation method of the transferor rotator 709 and the tilt rotator 710 has been adjusted.
[0071] In this embodiment, the structure of the lifting sleeve 705 is the same as in Embodiment 1, including a lifting sleeve cavity 70501, a sleeve 70502, and a connecting cylinder 70503. However, the installation method of the transferor rotator 709 and the tilting rotator 710 is changed to be directly or indirectly connected to the lifting sleeve 705, omitting the slewing transition plate 712 and the frame connecting plate 713. The specific structure is as follows:
[0072] Installation of the transfer rotary 709:
[0073] A mounting base is welded onto the connecting sleeve 70503 of the lifting sleeve 705, and the fixing ring of the transferor rotator 709 is directly fixed to the mounting base with bolts. The rotating ring of the transferor rotator 709 is connected to the drill pipe transferor, and the rotating ring is driven to rotate by a motor or hydraulic motor to adjust the inclination angle of the drill pipe transferor.
[0074] Installation of the tilt slewing mechanism 710:
[0075] The fixed ring of the tilt rotator 710 is bolted to the fixed ring of the transfer rotator 709, forming a superimposed structure. The rotating ring of the tilt rotator 710 is bolted to the frame 11, and the rotating ring is driven to rotate by a motor or hydraulic motor to adjust the tilt angle of the frame 11.
[0076] Alternatively, another method can be used:
[0077] Installation of the tilt slewing mechanism 710:
[0078] A mounting base is welded onto the connecting cylinder 70503 of the lifting sleeve 705, and the fixing ring of the tilting rotator 710 is directly fixed to the mounting base by bolts. The rotating ring of the tilting rotator 710 is connected to the frame 11, and the tilting angle of the frame 11 is adjusted by a motor.
[0079] Installation of the transfer rotary 709:
[0080] The fixed ring of the rotary transferor 709 is bolted to the fixed ring of the tilting rotary transferor 710. The rotating ring is connected to the drill pipe transferor, and the tilting angle of the drill pipe transferor is adjusted by a motor drive.
[0081] In both alternative structures described above, the transferor rotator 709 and the tilt rotator 710 remain located on the same side of the lifting sleeve 705 and can be operated independently. Operators can adjust the tilt angle of the drill pipe transferor and the frame 11 separately by controlling their respective motors, achieving asynchronous adjustment. This design simplifies the structure while maintaining functional flexibility, making it suitable for different drilling rig configurations.
[0082] In another embodiment, the transferor rotator 709 or the tilt rotator 710 is directly mounted on the lifting sleeve 705, that is, the rotatable transition plate 712, the frame connecting plate 713 and the lifting sleeve 705 are manufactured as a single unit.
[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
