Description

Technical Field

[0002] The construction of inclined shafts in pumped-storage power stations is an important project, in which the accuracy of the pilot hole is crucial to subsequent construction. At present, inclined shaft construction usually uses a directional drill or a reverse borehole drill to first form a pilot hole, and then expands the well by TBM or manual excavation. However, due to factors such as gravity and changes in geological conditions, the accuracy control of the pilot hole becomes increasingly difficult as the drilling distance increases. The existing pilot hole correction technology has the following main shortcomings. Traditional pilot hole correction mainly relies on manual experience judgment and operation, which is inefficient, has poor accuracy, and is easily affected by human factors. Some equipment uses mechanical mechanisms for correction, but the structure is complex, the operation is inconvenient, and it is difficult to achieve real-time dynamic adjustment. In addition, the power supply of existing equipment usually relies on external power or fuel, which limits the mobility and flexibility of the equipment.

[0003] Therefore, there is a need for a drilling correction auxiliary device and correction construction method that can quickly detect the correction effect and adjust the correction force dynamically, achieve self-sufficiency in power, be easy to operate, easy to maintain, effectively reduce construction costs and improve construction efficiency to meet the needs of the existing environment.

[0052] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0053] Example 1

[0054] Reference Figures 1-2 , this embodiment provides a drilling correction auxiliary device.

[0055] The load-bearing mechanism 1 is sleeved on the outside of the drill pipe to provide core support and frame parts. The inner ring 11 directly fits with the outer wall of the drill pipe. In order to ensure that the inner ring 11 can be installed along the outer wall of the drill pipe and will not be easily dislocated during the drilling process of the drill bit, the outer wall of the inner ring 11 can provide a limit with the outer wall of the drill pipe by using a concave and convex groove. Adding a protrusion to the outer wall of the drill pipe can limit the vertical position of the load-bearing mechanism 1.

[0056] The outer wall of the inner collar 11 is rotatably connected to the outer shell 12. The outer shell 12 can rotate along the outer wall of the inner collar 11 without falling. An electric mechanism 2 is disposed between the outer shell 12 and the inner collar 11. The electric mechanism 2 can be a conventional motor or a hollow rotating generator. The electric mechanism 2 is fixedly connected to the interior of the outer shell 12 and can rotate with the rotation of the outer shell 12, thereby providing power to the rotating generator, allowing the electric mechanism 2 to generate electricity and ensure the normal operation of the various functions of the positioning mechanism 3. The outer shell 12 and the inner collar 11 form a rotatable cavity for accommodating the electric mechanism 2 and the positioning mechanism 3.

[0057] A main control terminal 31, which can be a computer, is installed on the remote drilling rig's main control terminal. This terminal is used to aggregate and compare data from the entire positioning mechanism 3 and adjust the correction effect. A positioning member 32 is fixed to one side of the power mechanism 2 and can monitor the position and angular deviation of the entire drill bit in real time.

[0058] The transmission element 33 uses a wireless transmission device to aggregate the data collected by the positioning element 32 to the main control terminal 31. The main control terminal 31 collects data before the entire drilling operation. During the drilling process, the data of the positioning element 32 is also transmitted to the main control terminal 31 in real time. The main control terminal 31 can use data comparison to correct deviations, ensuring that the drill bit does not produce large angular deviations during the entire drilling operation, ensuring the construction accuracy of the ultra-long pilot hole, and improving drilling efficiency and safety.

[0059] Example 2

[0060] Reference Figures 1 to 5 This embodiment is based on the previous embodiment, and differs from the previous embodiment in that:

[0061] In the center of the outer shell 12, a conducting hole 121 is hollowed out, and the inner wall of the conducting hole 121 is used to fit and dock with the outer wall of the inner ring 11. Grooves are respectively opened on the inner wall of the conducting hole 121 and the outer wall of the inner ring 11 to symmetrically form a rolling groove 111.

[0062] Multiple balls 1111 are slidably mounted within the rolling groove 111, allowing them to roll efficiently along the groove. A retaining ring 1112 is fixedly mounted within the rolling groove 111, with a retaining ring 1112 having two upper and lower sections, ensuring that its inner walls conform to the outer walls of the balls 1111. This ensures that the balls 1111 remain stably positioned and provide smooth transmission, ensuring that the outer shell 12 can effectively and safely rotate along the inner ring 11, and that the power mechanism 2 and positioning mechanism 3 are in coordinated, stable, and safe motion.

[0063] A protective cavity 14 is formed between the outer shell 12 and the inner ring 11. An electrical storage element 21 is housed within this cavity, located on one side of and connected to the power mechanism 2. Because the power mechanism 2 preferably utilizes a hollow rotating generator, the outer shell 12 and inner ring 11 rotate in unison to deliver power and allow the electrical storage element 21 to store electricity. A protective frame 141 is fixedly mounted to the exterior of the electrical storage element 21, which is fixedly connected to the inner wall of the outer shell 12.

[0064] An anchor plate 15 is provided on the inner wall of the outer shell 12 and is located on one side of the power mechanism 2. Multiple anchor plates 15 may be provided, and anchor bolts 151 are provided through the anchor plates 15. Multiple anchor holes 22 may also be provided on the upper and lower sides of the power mechanism 2. The anchor holes 22 are configured to correspond to the anchor bolts 151. Once the anchor bolts 151 are inserted into the anchor holes 22, they can effectively secure the power mechanism 2.

[0065] A plurality of hydraulic assemblies 34 are provided on the outer wall of the outer shell 12 , and the hydraulic assembly 34 can provide a pressure force for the drilling operation of the entire drill bit. A fixedly connected hydraulic sensor 341 is fixedly connected to one side of the hydraulic assembly 34 , and the hydraulic sensor 341 is located inside the outer shell 12 .

[0066] The hydraulic assembly 34 and the hydraulic sensor 341 are both electrically connected to the transmission element 33, allowing real-time data to be transmitted to the main control terminal 31 via the transmission element 33. The main control terminal 31 then compares the data and issues subsequent correction instructions. The center of the inner collar 11 is positioned along the central drill rod 4. A connecting groove 41 is fixedly formed on the outer wall of the central drill rod 4, while a connecting ridge 112 is fixedly formed on the inner wall of the center of the inner collar 11. The number of connecting grooves 41 and connecting ridges 112 corresponds, and the connecting ridges 112 are able to slidably engage with the connecting grooves 41, ensuring that the inner collar 11 can slide linearly along the central drill rod 4 without misalignment.

[0067] A limiting boss 42 is fixedly connected to the outer wall of the central drill rod 4. The limiting boss 42 contacts the bottom surface of the inner ring 11, thereby ensuring that the inner ring 11 is restricted in a suitable position.

[0068] Example 3

[0069] Reference Figures 1 to 7 This embodiment is based on the previous embodiment, and differs from the previous embodiment in that:

[0070] During the drilling preparation process, the main control terminal 31 inputs information such as the drilling direction, depth, and hole mouth coordinates as pre-set drilling information. Before drilling begins, the drilling deviation control accuracy is also input. As a correction standard for subsequent drilling, the main control terminal 31 calculates the initial pressure and drilling angle deviation based on data collected by the positioning component 32 and the hydraulic sensor 341.

[0071] During the drilling operation, each level measures the vector angle of the central drill rod 4 through the positioning component 32 every 1 to 2 meters of drilling, and transmits the drill rod vector and number information to the main control terminal 31 through the transmission component 33 for storage.

[0072] Before the central drill rod 4 is in place, the hydraulic assembly 34 contracts to ensure smooth operation. After the central drill rod 4 is in place, the hydraulic assembly 34 extends to support the hole wall to complete the fixation.

[0073] During the drilling process, the power mechanism 2 rotates following the rotation of the central drill rod 4, thereby providing power to the positioning part 32, the hydraulic sensor 341 and the transmission part 33. The main control end 31 compares the real-time measured data of the positioning part 32 and the hydraulic sensor 341 with the initial pressure and the drilling angle deviation, and infers the reverse acting force, thereby reversely calculating the actual pressure of the hydraulic assembly 34, which is convenient for subsequent adjustments.

[0074] When the deviation correction rate does not meet the actual demand, the main control end 31 adjusts the pressure of the hydraulic assembly 34. When the deviation correction rate is too fast, the main control end 31 controls the adjustment of the hydraulic assembly 34 to increase the pressure of each hydraulic assembly 34 to ensure that the pressure resultant is reduced. When the deviation correction rate is too slow, the main control end 31 controls the adjustment of the hydraulic assembly 34 to reduce the pressure of each pressure assembly 34 to ensure that the pressure resultant is increased.

[0075] When the deviation correction rate meets the requirements, the main control end 31 maintains the hydraulic deviation correction pressure, remeasures after drilling 1 to 2 meters, and calculates the deviation. If the deviation is still within the reasonable range of deviation control accuracy, it means that the deviation correction is completed. If it is not within the reasonable range after remeasurement, the pressure adjustment is continued until the deviation correction is completed.

[0076] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
