Description

Technical Field

[0001] This invention relates to the field of oil drilling technology, and more particularly to an oil extraction drilling device. Background Technology

[0002] In oil extraction operations, drilling equipment is the core equipment for drilling into formations and obtaining oil and gas resources. Drill pipe splicing is a critical process in drilling—as drilling depth increases, the drilling stroke needs to be extended by connecting drill pipe sections one by one. The quality and efficiency of this operation directly affect the overall extraction progress and cost. Drill pipe splicing not only requires ensuring the coaxiality of the drill pipe assembly to avoid malfunctions such as deviation and stuck drill pipe during drilling, but also needs to consider operational safety and reduce manual labor intensity. This is a core requirement for the large-scale and efficient development of oil extraction.

[0003] Currently, the drill pipe splicing process in oil drilling equipment suffers from significant technical deficiencies. Existing equipment largely relies on manual or semi-automated operations for splicing: manual labor involves carrying heavy drill pipes to align with the joints, resulting in extreme labor intensity and a high risk of drill pipe coaxiality deviations due to operational errors. This leads to drill pipe wear and decreased drilling accuracy. Furthermore, traditional splicing methods are cumbersome, requiring manual alignment and tightening of multiple steps, making splicing a single drill pipe time-consuming, especially in deep drilling scenarios requiring multiple splices. Overall operational efficiency is extremely low. The instability of manual operation further amplifies coaxiality errors, potentially leading to drill pipe breakage and drilling accidents. This not only impacts extraction progress but also increases equipment maintenance and accident handling costs. As oil extraction expands into deeper and more complex formations, the requirements for the accuracy, safety, and efficiency of drill pipe splicing are increasingly stringent. Traditional manual splicing methods can no longer meet the demands of large-scale extraction, becoming a bottleneck restricting the improvement of oil extraction efficiency. Therefore, urgent improvements are needed. Summary of the Invention

[0072] Reference Figures 1 to 13 The following is a further description of an embodiment of an oil drilling equipment according to the present invention.

[0073] An oil drilling equipment includes a drilling platform 1 and a truss 2 fixedly mounted on the drilling platform 1. Four symmetrically arranged support platforms 3 are fixedly mounted below the drilling platform 1. A control device 4 is mounted on any of the support platforms 3. Two symmetrically distributed limiting plates 5 are fixedly mounted on the truss 2. A through groove 6 is formed on the surface of the drilling platform 1 where the support platforms 3 are located. A drive groove 7 communicating with the through groove 6 is formed on the surface of the drilling platform 1 where the truss 2 is located. An auxiliary groove 8 is formed within the drive groove 7. A first limiting groove 9 is formed within the drive groove 7. Two symmetrically distributed inner cavities 10 are formed inside the drilling platform 1, and both inner cavities 10 communicate with the drive groove 7. An annular groove 11 is formed on the side of the drilling platform 1. A second limiting groove 12 is formed within the annular groove 11. An internal groove 13 communicating with the annular groove 11 is formed inside the drilling platform 1. A drilling mechanism for drilling is mounted on the truss 2. The drilling mechanism includes:

[0074] The hoist 14 is mounted on the truss 2 and is electrically connected to the control device 4;

[0075] The winding roller 15 is rotatably mounted on the truss 2 and is fixedly connected to the output end of the hoist 14. A steel rope 16 for lifting the drilling mechanism is wound on the winding roller 15.

[0076] The lifting plate 17 is detachably fixed to one end of the steel rope 16, and the lifting plate 17 is slidably connected to the adjacent limiting plate 5. The lifting plate 17 has an inner groove 18 and column grooves 19 symmetrically distributed on both sides of the inner groove 18.

[0077] Hydraulic push rod 20 is located in the inner groove 18 and is fixedly connected to the lifting plate 17. Hydraulic push rod 20 is electrically connected to the control device 4. The output end of hydraulic push rod 20 is fixedly connected to a connecting platform 21. A guide column 22 that is slidably connected to the column groove 19 is fixedly provided on the surface of the connecting platform 21 near the column groove 19. By providing the guide column 22, the connecting platform 21 can be guided and limited during movement, thereby preventing the moving path of the connecting platform 21 from deviating.

[0078] The bearing unit is fixedly installed at one end of the guide column 22 near the drilling platform 1. The bearing unit includes:

[0079] The connecting column 23 is fixedly installed on the connecting platform 21, and the axis of the connecting column 23 coincides with the axis of the through groove 6. A fixing frame 24 is fixedly installed at the end of the connecting column 23 away from the connecting platform 21, and a shock-absorbing groove 25 is opened on the side of the fixing frame 24 away from the connecting column 23.

[0080] There are multiple fixing rods 26, and the multiple fixing rods 26 are evenly distributed in the damping groove 25. The fixing rods 26 are fixedly connected to the fixing frame 24. Each fixing rod 26 is fitted with a damping spring 27, and the damping spring 27 is always in a compressed state.

[0081] The buffer ring 28 is slidably mounted on the fixed frame 24, and the buffer ring 28 is slidably connected to the fixed rod 26.

[0082] It should be noted that by setting up a shock-absorbing spring 27 and a buffer ring 28 that are always in a compressed state, when the electric push rod 29 applies intermittent pressure to the buffer ring 28 through the vibration plate 31 and the vibration rod 30, the buffer ring 28 and the shock-absorbing spring 27 can effectively buffer the instantaneous impact force applied by the electric push rod 29, thereby avoiding the shortening of the service life of the parts due to excessive instantaneous impact force, and thus reducing the cost of oil drilling to a certain extent.

[0083] The power unit, mounted on the fixed frame 24 and electrically connected to the control device 4, includes:

[0084] Multiple electric push rods 29 are evenly distributed on the fixed frame 24 and fixedly connected to the fixed frame 24. The electric push rods 29 are also electrically connected to the control device 4. It should be noted that by providing electric push rods 29, when the drill bit 44 is drilling, in addition to the pressure applied to the drill bit 44 by the weight of the drill rod 40, additional pressure can be applied by the electric push rods 29, thereby improving the drilling efficiency of the drill bit 44 when drilling rocks to a certain extent. At the same time, the control device 4 can control the electric push rods 29 to apply continuous or intermittent pressure, thus adapting to the drilling needs of different geological conditions.

[0085] There are multiple vibration transmission rods 30, and the multiple vibration transmission rods 30 are evenly distributed on the buffer ring 28. The vibration transmission rods 30 are fixedly connected to the buffer ring 28. A vibration transmission plate 31 is fixedly provided at the end of the vibration transmission rod 30 away from the buffer ring 28. The vibration transmission plate 31 is in contact with the output end of the electric push rod 29.

[0086] An extension motor 32 is fixedly mounted on a vibration transmission plate 31 and electrically connected to a control device 4. A transmission plate 33 is fixedly connected to the output end of the extension motor 32. Multiple evenly distributed transmission rods 34 are fixedly mounted on the surface of the transmission plate 33 near the drilling platform 1. It should be noted that the extension motor 32 provides additional power to the drill rod 40, improving the drilling efficiency of the device to some extent. Furthermore, when a longer drilling depth is required, the extension motor 32 can drive the angular drill rod 38 to rotate in the opposite direction, thus separating the angular drill rod 38 from the connected drill rod 40, eliminating the need for manual operation and further improving the drilling efficiency of the device.

[0087] The drilling section, mounted on the fixed frame 24, is electrically connected to the control device 4. The drilling section includes:

[0088] The transmission block 35 is rotatably disposed within the buffer ring 28 and fixedly connected to the transmission rod 34. An electromagnetic chuck 36 electrically connected to the control device 4 is fixedly disposed within the transmission block 35. A first connecting groove 37 is formed through the middle of the electromagnetic chuck 36. A square drill rod 38 is disposed on the electromagnetic chuck 36. The square drill rod 38 is detachably fixedly connected to the electromagnetic chuck 36. A second connecting groove 39 communicating with the first connecting groove 37 is formed through the middle of the square drill rod 38.

[0089] The drill rod 40 is detachably fixed to the end of the square drill rod 38 away from the fixed frame 24. A third connecting groove 41 communicating with the second connecting groove 39 is opened through the middle of the drill rod 40. A drill base 42 is detachably fixed to the end of the drill rod 40 away from the fixed frame 24. A fourth connecting groove 43 communicating with the third connecting groove 41 is opened through the middle of the drill base 42. Multiple evenly distributed drill bits 44 are detachably fixed to the drill base 42.

[0090] It should be noted that when the square drill rod 38, drill rod 40 and drill base 42 are connected, the first connecting groove 37, the second connecting groove 39, the third connecting groove 41 and the fourth connecting groove 43 are connected. This arrangement facilitates the input of external cooling and lubricating fluid to the surface of the drill bit 44 during drilling, thereby cooling the drill bit 44 and also facilitates the subsequent removal of waste chips.

[0091] During drilling, the control device 4 starts the pneumatic motor 45, causing the drive gear 46, which is fixedly connected to the output end of the pneumatic motor 45, to rotate. This, in turn, causes the rotating gear 47, which meshes with the drive gear 46, to rotate, thereby driving the connecting rod 50, which is fixedly connected to the rotating gear 47, to rotate. This, in turn, causes the drive disk 51, which is fixedly connected to the connecting rod 50, to rotate. Through the engagement between the square groove 48 on the rotating gear 47 and the square groove 48 on the drive disk 51 and the square drill rod 38, the square drill rod 38 is driven to rotate, thereby causing the drill rod 40, which is detachably fixedly connected to the square drill rod 38, to rotate. This, in turn, causes the drill rod 40, which is detachably fixedly connected to the drill rod 40, to rotate. The drill base 42, which is fixedly connected, rotates, causing the drill bit 44 mounted on the drill base 42 to rotate around the axis of the drill base 42. At the same time, the hydraulic push rod 20 is activated by the control device 4, which applies pressure to the vibration plate 31. The vibration plate 31 then applies pressure to the buffer ring 28 through the vibration rod 30, which in turn applies pressure to the transmission block 35. The transmission block 35 then applies pressure to the square drill rod 38 through the electromagnetic chuck 36, which in turn applies pressure to the drill base 42 through the drill rod 40. This allows the drill bit 44 to apply pressure to the soil while rotating, thus enabling drilling operations.

[0092] The drilling platform 1 is equipped with a drive mechanism for providing power to the drilling mechanism. The drive mechanism includes:

[0093] There are two pneumatic motors 45, and the two pneumatic motors 45 are symmetrically distributed on the drilling platform 1. The pneumatic motors 45 are electrically connected to the control device 4.

[0094] The drive gear 46 is rotatably disposed within the inner cavity 10, and the drive gear 46 is fixedly connected to the output end of the pneumatic motor 45.

[0095] Rotating gear 47 is rotatably disposed in drive groove 7, and the axis of rotating gear 47 coincides with the axis of through groove 6. Rotating gear 47 meshes with drive gear 46. A square groove 48 is provided through the middle of rotating gear 47. The square groove 48 is slidably connected to square drill rod 38. A first limiting ring 49 is fixedly disposed on the surface of rotating gear 47 near the first limiting groove 9. The first limiting ring 49 is rotatably connected to the first limiting groove 9.

[0096] There are multiple connecting rods 50, and the multiple connecting rods 50 are evenly distributed on the rotating gear 47. The connecting rods 50 are fixedly connected to the rotating gear 47.

[0097] The drive disk 51 is fixedly installed at the end of the connecting rod 50 away from the rotating gear 47, and the axis of the drive disk 51 coincides with the axis of the rotating gear 47. A square groove 48 is also opened through the middle of the drive disk 51, and multiple evenly distributed slots 52 are opened on the surface of the drive disk 51.

[0098] By opening square grooves 48 on both the rotating gear 47 and the drive disk 51, the rotating gear 47 and the drive disk 51 can synchronously drive the square drill rod 38 to rotate, which to a certain extent ensures the stability of the square drill rod 38 when rotating.

[0099] There are multiple auxiliary wheels 53, which are evenly distributed in the auxiliary groove 8. The auxiliary wheels 53 are rotatably connected to the drilling platform 1 and fit against the drive disk 51. By setting the auxiliary wheels 53, the resistance encountered by the drive disk 51 when it rotates is greatly reduced, the smoothness of the drive disk 51 rotation is improved to a certain extent, and the power damage of the drive disk 51 during rotation is reduced.

[0100] The fixing part has multiple sets, and each set of fixing parts is respectively disposed in the slot 52. The fixing part is used to fix the drill rod 40 when the connecting rod extends to the drill rod 40. The fixing part includes:

[0101] The electric telescopic rod 54 is located in the slot 52 and is electrically connected to the control device 4;

[0102] The sliding block 55 is slidably disposed in the slot 52 and fixedly connected to the output end of the electric telescopic rod 54;

[0103] The locking block 56 is fixedly mounted on the sliding block 55. The locking block 56 is used to fix the drill rod 40 that passes through the square groove 48 when the connecting rod extends the drill rod 40.

[0104] By providing a fixing part, the clamping block 56 can clamp and fix the drill rod 40 when it is extended to the drill rod. At the same time, the synchronous movement of each clamping block 56 ensures that the axis of the drill rod 40 always coincides with the center line of the square drill rod 38, which facilitates the subsequent extension of the drill rod 40.

[0105] It should be noted that while the drive mechanism drives the drill rod 40 to rotate, the control device 4 controls the extension motor 32 to start, thereby causing the transmission plate 33, which is fixedly connected to the output end of the extension motor 32, to rotate. This, in turn, drives the transmission rod 34, which is fixedly connected to the transmission plate 33, to rotate. This causes the transmission block 35, which is fixedly connected to the transmission rod 34, to rotate. This, in turn, causes the electromagnetic chuck 36, which is fixedly connected to the transmission block 35, to rotate. This provides additional power to the drill rod 40, which is detachably fixedly connected to the electromagnetic chuck 36, thereby improving the drilling efficiency of this device to a certain extent.

[0106] The drilling platform 1 is equipped with a rod extension mechanism, which includes:

[0107] The second limiting ring 57 is rotatably positioned within the second limiting groove 12;

[0108] The internal gear ring 58 is located in the annular groove 11 and is fixedly connected to the second limiting ring 57.

[0109] Multiple connecting blocks 59 are evenly distributed on the outer surface of the internal gear ring 58. Each connecting block 59 is fixedly connected to the internal gear ring 58. A clamping portion is fixedly provided at the end of each connecting block 59 away from the internal gear ring 58. The clamping portion includes:

[0110] U-shaped plate 62 is fixedly installed at the end of connecting block 59 away from drilling platform 1;

[0111] Two hydraulic telescopic rods 63 are provided, and the two hydraulic telescopic rods 63 are symmetrically arranged on the U-shaped plate 62. The hydraulic telescopic rods 63 are fixedly connected to the U-shaped plate 62 and electrically connected to the control device 4.

[0112] Clamping block 64 is located at the output end of hydraulic telescopic rod 63 and is detachably fixed to hydraulic telescopic rod 63. Clamping block 64 clamps the drill rod 40 to be connected to the rod.

[0113] The power unit, mounted on the drilling platform 1 and electrically connected to the control device 4, drives the internal gear ring 58 to rotate. The power unit includes:

[0114] The rotating motor 60 is fixedly mounted on the drilling platform 1 and electrically connected to the control device 4;

[0115] The built-in gear 61 is located in the built-in groove 13 and is fixedly connected to the output end of the rotating motor 60. The built-in gear 61 meshes with the internal gear ring 58.

[0116] When it is necessary to increase the drilling depth, the pneumatic motor 45 and the extension motor 32 are shut off by the control device 4, ultimately stopping the drill bit 44 from rotating. Then, the control device 4 controls the hoist 14 to start, causing the winding roller 15, which is fixedly connected to the output end of the hoist 14, to rotate. This causes the winding roller 15 to wind the steel rope 16, which in turn causes the lifting plate 17, which is fixedly connected to the steel rope 16, to rise. This, in turn, causes the connecting platform 21, which is fixedly connected to the hydraulic push rod 20, to rise. This causes the connecting column 23, which is fixedly connected to the connecting platform 21, to drive the fixed frame 24 to rise, thereby causing the electromagnetic chuck 36 located in the fixed frame 24 to rise. The square drill pipe 38 is raised, which in turn raises the drill pipe 40, which is detachably and fixedly connected to the square drill pipe 38, until one end of the drill pipe 40 connected to the square drill pipe 38 exceeds the drilling platform 1 by a certain height (this height is the preset height in the operation and construction manual). Then, the hoist 14 is turned off by the control device 4 and the electric telescopic rod 54 is started, so that the electric telescopic rod 54 pushes the sliding block 55 to slide in the slot 52, so that the locking block 56 fixedly connected to the sliding block 55 moves toward the surface of the drill pipe 40 until each locking block 56 contacts the surface of the drill pipe 40 and applies corresponding pressure to fix the drill pipe 40.Then, the control device 4 controls the extension motor 32 to rotate in the reverse direction, thereby causing the transmission plate 33, which is fixedly connected to the output end of the extension motor 32, to rotate in the reverse direction. This, in turn, drives the transmission rod 34, which is fixedly connected to the transmission plate 33, to rotate in the reverse direction. Consequently, the transmission block 35, which is fixedly connected to the transmission rod 34, rotates in the reverse direction, which in turn causes the electromagnetic chuck 36, which is fixedly connected to the transmission block 35, to rotate in the reverse direction. This, in turn, causes the square drill rod 38, which is detachably fixedly connected to the electromagnetic chuck 36, to rotate in the reverse direction, thus achieving the disassembly of the square drill rod 38 from the drill rod 40. Then, the control device 4 shuts down the extension motor 32 and controls the hydraulic push rod 20 to start, thereby causing the hydraulic push rod 20 to rotate in the reverse direction. The fixed connecting platform 21 moves, causing the connecting column 23, which is fixedly connected to the connecting platform 21, to move the fixed frame 24. This causes the electromagnetic chuck 36, located within the fixed frame 24, to move the square drill rod 38 until the axis of the square drill rod 38 coincides with the axis of the extension drill rod 40, which is clamped and fixed below by the clamping block 64. Then, the control device 4 closes the hydraulic push rod 20 and controls the hoist 14 to start, causing the winding roller 15, which is fixedly connected to the output end of the hoist 14, to release the steel rope 16. This causes the square drill rod 38 to descend until the screw end of the square drill rod 38 is inserted into the drill rod 40. Then, the hoist 14 is closed and the extension motor 32 is started. This causes the square drill rod 38 to rotate, thus completing the connection between the square drill rod 38 and the drill rod 40 to be connected. Then, the control device 4 shuts off the extension motor 32 and controls the hydraulic telescopic rod 63 directly below the square drill rod 38 to retract. At the same time, the hoist 14 is started, causing the square drill rod 38 to drive the drill rod 40 to be connected to rise until the height of the drill rod 40 to be connected to exceeds the height of the drill rod 40 fixed by the clamping block 56. Then, the hoist 14 is shut off and the hydraulic push rod 20 is controlled to retract, causing the connecting platform 21 to drive the fixing frame 24 to reset through the connecting column 23. This allows the square drill rod 38, which is detachably fixed to the electromagnetic chuck 36 inside the fixing frame 24, to be connected to the fixed platform 24. Move the drill rod 40 directly above the drill rod 40 fixed by the locking block 56, so that the drill rod 40 to be connected is positioned directly above the drill rod 40 fixed by the locking block 56. Then, close the hydraulic push rod 20 and start the hoist 14, so that one end of the drill rod 40 to be connected is inserted into the drill rod 40 fixed by the locking block 56 directly below. Then, close the hoist 14 and start the extension motor 32. Through the transmission of a series of components, the drill rod 40 to be connected rotates, thus completing the connection and fixation between the drill rod 40 to be connected and the drill rod 40 fixed by the locking block 56. Drilling operations can then continue. When it is necessary to deepen the drilling depth again, the above operation can be repeated.

[0117] After the drill rod 40 is extended, the control device 4 controls the start of the rotary motor 60, which causes the built-in gear 61, which is fixedly connected to the output end of the rotary motor 60, to rotate. Through the meshing between the built-in gear 61 and the internal gear ring 58, the internal gear ring 58 is driven to rotate, which causes the connecting block 59 on the internal gear ring 58 to rotate around the axis of the internal gear ring 58. This causes the clamping part on the connecting block 59 to rotate around the axis of the internal gear ring 58 until the drill rod 40, which is clamped and fixed by the clamping part, is rotated to the front of the drive disk 51, ready for the next extension.

[0118] Compared to the current method where the extension of drill pipe 40 still requires a large amount of manual intervention, which not only greatly reduces the efficiency of drill pipe 40 extension but also poses a certain threat to the personal safety of workers, this device, by setting up a rod extension mechanism, can automatically complete the extension of drill pipe 40, greatly reducing the amount of manual intervention during the extension of drill pipe 40. This not only ensures the coaxiality of the drill pipe 40 group after extension but also greatly improves the efficiency of drill pipe 40 extension while ensuring the personal safety of workers.

[0119] Working principle: During drilling, the control device 4 starts the pneumatic motor 45, causing the drive gear 46, which is fixedly connected to the output end of the pneumatic motor 45, to rotate. This, in turn, causes the rotating gear 47, which meshes with the drive gear 46, to rotate, thereby driving the connecting rod 50, which is fixedly connected to the rotating gear 47, to rotate. This, in turn, causes the drive disk 51, which is fixedly connected to the connecting rod 50, to rotate. Through the cooperation between the square groove 48 on the rotating gear 47 and the square groove 48 on the drive disk 51 and the square drill rod 38, the square drill rod 38 is driven to rotate. This, in turn, causes the drill rod 40, which is detachably fixedly connected to the square drill rod 38, to rotate, thereby driving the drill rod 40, which is detachably fixedly connected to the drill rod 40, to rotate. The detachable fixed connection of the drill base 42 rotates, causing the drill bit 44 mounted on the drill base 42 to rotate around the axis of the drill base 42. At the same time, the control device 4 controls the hydraulic push rod 20 to start, so that the hydraulic push rod 20 applies pressure to the vibration plate 31, which in turn applies pressure to the buffer ring 28 through the vibration rod 30, which in turn applies pressure to the transmission block 35, which in turn applies pressure to the square drill rod 38 through the electromagnetic chuck 36, which in turn applies pressure to the drill base 42 through the drill rod 40. Thus, the drill bit 44 can also apply pressure to the soil while rotating, thereby realizing the drilling work.

[0120] It should be noted that while the drive mechanism drives the drill rod 40 to rotate, the control device 4 controls the extension motor 32 to start, thereby causing the transmission plate 33, which is fixedly connected to the output end of the extension motor 32, to rotate. This, in turn, drives the transmission rod 34, which is fixedly connected to the transmission plate 33, to rotate. This causes the transmission block 35, which is fixedly connected to the transmission rod 34, to rotate. This, in turn, causes the electromagnetic chuck 36, which is fixedly connected to the transmission block 35, to rotate. This provides additional power to the drill rod 40, which is detachably fixedly connected to the electromagnetic chuck 36, thereby improving the drilling efficiency of this device to a certain extent.

[0121] When it is necessary to increase the drilling depth, the pneumatic motor 45 and the extension motor 32 are shut off by the control device 4, ultimately stopping the drill bit 44 from rotating. Then, the control device 4 controls the hoist 14 to start, causing the winding roller 15, which is fixedly connected to the output end of the hoist 14, to rotate. This causes the winding roller 15 to wind the steel rope 16, which in turn causes the lifting plate 17, which is fixedly connected to the steel rope 16, to rise. This, in turn, causes the connecting platform 21, which is fixedly connected to the hydraulic push rod 20, to rise. This causes the connecting column 23, which is fixedly connected to the connecting platform 21, to drive the fixed frame 24 to rise, thereby causing the electromagnetic chuck 36 located in the fixed frame 24 to rise. The square drill pipe 38 is raised, which in turn raises the drill pipe 40, which is detachably and fixedly connected to the square drill pipe 38, until one end of the drill pipe 40 connected to the square drill pipe 38 exceeds the drilling platform 1 by a certain height (this height is the preset height in the operation and construction manual). Then, the hoist 14 is turned off by the control device 4 and the electric telescopic rod 54 is started, so that the electric telescopic rod 54 pushes the sliding block 55 to slide in the slot 52, so that the locking block 56 fixedly connected to the sliding block 55 moves toward the surface of the drill pipe 40 until each locking block 56 contacts the surface of the drill pipe 40 and applies corresponding pressure to fix the drill pipe 40.Then, the control device 4 controls the extension motor 32 to rotate in the reverse direction, thereby causing the transmission plate 33, which is fixedly connected to the output end of the extension motor 32, to rotate in the reverse direction. This, in turn, drives the transmission rod 34, which is fixedly connected to the transmission plate 33, to rotate in the reverse direction. Consequently, the transmission block 35, which is fixedly connected to the transmission rod 34, rotates in the reverse direction, which in turn causes the electromagnetic chuck 36, which is fixedly connected to the transmission block 35, to rotate in the reverse direction. This, in turn, causes the square drill rod 38, which is detachably fixedly connected to the electromagnetic chuck 36, to rotate in the reverse direction, thus achieving the disassembly of the square drill rod 38 from the drill rod 40. Then, the control device 4 shuts down the extension motor 32 and controls the hydraulic push rod 20 to start, thereby causing the hydraulic push rod 20 to rotate in the reverse direction. The fixed connecting platform 21 moves, causing the connecting column 23, which is fixedly connected to the connecting platform 21, to move the fixed frame 24. This causes the electromagnetic chuck 36, located within the fixed frame 24, to move the square drill rod 38 until the axis of the square drill rod 38 coincides with the axis of the extension drill rod 40, which is clamped and fixed below by the clamping block 64. Then, the control device 4 closes the hydraulic push rod 20 and controls the hoist 14 to start, causing the winding roller 15, which is fixedly connected to the output end of the hoist 14, to release the steel rope 16. This causes the square drill rod 38 to descend until the screw end of the square drill rod 38 is inserted into the drill rod 40. Then, the hoist 14 is closed and the extension motor 32 is started. This causes the square drill rod 38 to rotate, thus completing the connection between the square drill rod 38 and the drill rod 40 to be connected. Then, the control device 4 shuts off the extension motor 32 and controls the hydraulic telescopic rod 63 directly below the square drill rod 38 to retract. At the same time, the hoist 14 is started, causing the square drill rod 38 to drive the drill rod 40 to be connected to rise until the height of the drill rod 40 to be connected to exceeds the height of the drill rod 40 fixed by the clamping block 56. Then, the hoist 14 is shut off and the hydraulic push rod 20 is controlled to retract, causing the connecting platform 21 to drive the fixing frame 24 to reset through the connecting column 23. This allows the square drill rod 38, which is detachably fixed to the electromagnetic chuck 36 inside the fixing frame 24, to be connected to the fixed platform 24. Move the drill rod 40 directly above the drill rod 40 fixed by the locking block 56, so that the drill rod 40 to be connected is positioned directly above the drill rod 40 fixed by the locking block 56. Then, close the hydraulic push rod 20 and start the hoist 14, so that one end of the drill rod 40 to be connected is inserted into the drill rod 40 fixed by the locking block 56 directly below. Then, close the hoist 14 and start the extension motor 32. Through the transmission of a series of components, the drill rod 40 to be connected rotates, thus completing the connection and fixation between the drill rod 40 to be connected and the drill rod 40 fixed by the locking block 56. Drilling operations can then continue. When it is necessary to deepen the drilling depth again, the above operation can be repeated.
