Description
Technical Field
[0001] This invention relates to the field of raise pipe technology, and in particular to a raise pipe with a diameter of 10 meters. Background Technology
[0002] Raise drilling technology is widely used in engineering fields such as mining, water conservancy, and transportation to excavate underground passages such as vertical shafts and inclined shafts. Among them, large-diameter (10 meters and above) raise drilling is subject to high construction difficulty and load requirements, which places extremely high demands on the structural strength, connection stability, and sealing performance of the drill pipe. The raise drill pipe is the core load-bearing and force-transmitting component of the raise drilling rig and is mainly used in pilot hole drilling and hole enlargement operations in underground mining and civil engineering projects.
[0003] Currently, in the use of existing raise pipes, especially in the assembly and connection of adjacent raise pipes, the threaded connection between the pipes is subjected to high-frequency vibration and heavy load for a long time, which can easily lead to loosening and stripping. In addition, the thread surface is prone to seizing, which affects the efficiency of pipe assembly and disassembly. Furthermore, the anti-seizing agent applied during thread connection needs to be applied in advance, which is cumbersome and reduces efficiency. Summary of the Invention
[0004] This invention addresses the technical problems encountered during the assembly and connection of adjacent raise pipes. These problems include the threaded connection between the pipes, which is subject to long-term high-frequency vibration and heavy loads, leading to loosening, stripping, and seizing on the thread surface, affecting the efficiency of pipe assembly and disassembly. Furthermore, the need for pre-application of anti-seizing agent during thread connection is cumbersome and reduces efficiency. The invention provides a raise pipe with a diameter of 10 meters.
[0005] The present invention solves the above-mentioned technical problems through the following technical solutions: This invention provides a raise pipe with a diameter of 10 meters, the raise pipe comprising: The reverse drilling pipe body has a lower threaded connector fixedly connected to its lower end and an upper threaded connector fixedly connected to its upper end. A rod reinforcement assembly is sleeved on the outside of the raise pipe body to enhance the raise pipe body's resistance to deformation and torque, in order to meet the high-intensity operation requirements of 10-meter diameter raise pipe drilling. An anti-seize agent adding mechanism is provided on the outer side of the top of the upper threaded connector. The anti-seize agent adding mechanism is used to add anti-seize agent while connecting the lower threaded connector to the upper threaded connector of the adjacent drill rod. The extrusion linkage unit is installed at the top of the raise pipe body. The extrusion linkage unit drives the anti-galling agent addition mechanism to work under the push of the threaded connection of the adjacent raise pipe body. An anti-reverse locking mechanism is provided, comprising an upper locking component and a lower locking component. The upper locking component is installed at the top of the raise pipe body, and the lower locking component is installed at the bottom of the raise pipe body. It is used to prevent reversal locking after the adjacent raise pipe bodies are securely connected.
[0006] Furthermore, the riser drill pipe body is a hollow cylindrical structure, designed to accommodate the load requirements of 10-meter diameter riser drilling. Both the upper and lower threaded connectors are made of high-strength alloy material and have a wear-resistant coating on their surfaces.
[0007] Furthermore, the rod reinforcement assembly includes a reinforcement plate and a fixing ring. The fixing ring is sleeved on the surface of the raise drill pipe body. There are multiple fixing rings, which are evenly distributed along the axial direction of the raise drill pipe body. There are multiple reinforcement plates, which are evenly distributed along the circumference of the raise drill pipe body. The fixing ring is welded to the reinforcement plate as a whole.
[0008] Furthermore, the anti-seize agent addition mechanism includes a replenishing shell, an annular connecting cavity, and a shell sealing cap. The replenishing shell is fixedly sleeved on the outer surface of the upper threaded connector. The shell sealing cap is sealed to the top of the replenishing shell to seal the top of the replenishing shell. The inner side of the replenishing shell communicates with the injection cavity provided on the upper threaded connector. The end of the injection cavity communicates with the annular connecting cavity provided inside the upper threaded connector. The inner side of the annular connecting cavity is connected to a replenishing hole provided on the upper threaded connector. The end of the replenishing hole communicates with the inner cavity of the upper threaded connector.
[0009] Furthermore, the bottom surface of the supplementary shell is provided with an injection hole that communicates with the inner cavity of the supplementary shell, and a detachable sealing plug is provided in the injection hole to seal the injection hole.
[0010] Furthermore, multiple annular connecting cavities are equidistantly distributed along the axial direction of the threaded connector. The lowest annular connecting cavity is positioned at a height higher than the top of the supplementary shell. The annular connecting cavity is used to connect the injection cavity and the supplementary hole. Multiple annularly distributed supplementary holes are connected to the inner side of the annular connecting cavity.
[0011] Furthermore, the extrusion linkage unit is disposed between the upper threaded connector and the supplementary shell. The extrusion linkage unit includes an extrusion sealing ring, an elastic spring, a telescopic rubber sleeve, an extrusion column, and a guide sleeve. The extrusion sealing ring is slidably connected to the inner cavity of the supplementary shell. The top of the extrusion sealing ring is fixedly connected to the extrusion column. The top of the extrusion column penetrates the top side of the shell sealing cover. The elastic spring is sleeved on the surface of the extrusion column. The telescopic rubber sleeve is sleeved on the surface of the elastic spring. The top of the extrusion column is fixedly connected to the upper locking assembly. The top of the guide sleeve is fixedly connected to the bottom of the upper locking assembly. The bottom of the guide sleeve is slidably sleeved on the outer surface of the supplementary shell.
[0012] Furthermore, the number of extrusion columns is four, and the four extrusion columns are arranged in a ring on the top of the extrusion sealing ring. The extrusion sealing ring is used to extrude the anti-seize agent in the extrusion filling shell to the threaded connection of the adjacent raise pipe body.
[0013] Furthermore, the locking upper assembly includes a locking seat, a first anti-reverse tooth, a locking post, a locking spring, a connecting plate, a connecting block, and a rotating toothed ring. The locking seat is fixedly connected to the top of the extrusion post. The locking seat is slidably sleeved on the surface of the upper threaded connector. A plurality of first anti-reverse teeth are evenly distributed in a ring on the top of the locking seat. The locking post is slidably connected in a sliding groove opened on the side surface of the first anti-reverse tooth. The locking post is elastically connected to the sliding groove through a locking spring. A connecting plate is fixedly connected to the outer side of the end of the locking post that connects to the locking spring. A connecting block is fixedly connected to the end of the connecting plate. The connecting block is fixedly connected to the inner wall of the rotating toothed ring.
[0014] Furthermore, the inner wall of the rotating toothed ring is provided with a plurality of connecting blocks arranged in a ring. The number of connecting blocks is equal to the number of the first anti-reverse teeth, and the connecting blocks are slidably connected to the side surface of the corresponding first anti-reverse teeth.
[0015] Furthermore, the locking lower assembly includes a locking plate, a second anti-reverse tooth, and a locking groove. The locking plate is fixedly sleeved on the bottom surface of the lower threaded connector. The locking plate has an annular structure. Multiple second anti-reverse teeth are fixedly connected to the bottom end of the locking plate and are evenly distributed along the circumference of the locking plate. The side surface of the second anti-reverse tooth is provided with a locking groove. When adjacent raise pipe bodies are assembled, the second anti-reverse tooth meshes with the corresponding first anti-reverse tooth, and the locking groove on the side surface of the second anti-reverse tooth engages with the locking post on the side surface of the corresponding first anti-reverse tooth. Both the second anti-reverse tooth and the first anti-reverse tooth are helical tooth structures, used to prevent the raise pipe body from reversing and loosening during rotation operations.
[0016] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.
[0017] The positive and progressive effects of this invention are as follows: The aforementioned raised-well drill pipe with a diameter of 10 meters features a reinforced assembly consisting of a fixing ring and multiple arc-shaped reinforcing plates that fit snugly against the drill pipe body, forming a stable support structure. This effectively enhances the drill pipe's resistance to deformation and torque. Combined with a high-strength drill pipe body and threaded connector, it can withstand high-frequency vibrations and heavy loads during 10-meter diameter raised-well drilling, preventing deformation and breakage and ensuring construction safety.
[0018] In the connection of adjacent raise pipe bodies, the axial pressure driving the extrusion linkage unit during thread tightening can be realized to press the anti-seize agent from the replenishment shell into the annular connecting cavity, and then evenly seep into the thread gap through the circumferentially evenly arranged replenishment holes to form a continuous lubrication and protective layer. This avoids thread seizing, jamming, and corrosion under high load, high friction, and high temperature, facilitates drill pipe disassembly and assembly, improves construction efficiency, and greatly improves the smoothness of disassembly and assembly and the service life of the connection parts.
[0019] Under the action of the anti-reverse locking mechanism, the first and second anti-reverse teeth are helical teeth that match the working rotation direction of the drill pipe. The clockwise rotation is smooth and the reverse rotation is automatically locked. After the connection is in place, the locking spring automatically inserts the locking pin into the locking groove to form a mechanical positioning lock. This double-prevents the drill pipe from reversing and loosening under long-term torsional vibration, ensuring the reliability and safety of the connection in ultra-large diameter drilling operations.

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Example
[0039] like Figure 1-11As shown, the 10-meter diameter raise pipe includes: a raise pipe body 1, with a lower threaded connector 11 fixedly connected to the lower end of the raise pipe body 1 and an upper threaded connector 12 fixedly connected to the upper end of the raise pipe body 1; a rod reinforcement assembly 2, which is sleeved on the outside of the raise pipe body 1 to enhance the deformation resistance and torque resistance of the raise pipe body 1, in order to meet the high-intensity operation requirements of 10-meter diameter raise drilling; and an anti-seize agent addition mechanism 3, which is located on the outside of the top of the upper threaded connector 12. The anti-seize agent addition mechanism is used to connect the lower threaded connector 11 with the upper threaded connector 12 of the adjacent drill pipe. An anti-seize agent is added during connection to prevent seizing and jamming at the threaded connection due to high temperature, high pressure, and friction. It also provides rust prevention and lubrication, facilitating subsequent drill pipe disassembly. A compression linkage unit 4, installed at the top of the raise pipe body 1, drives the anti-seize agent addition mechanism 3 under the push of the threaded connection of adjacent raise pipe bodies 1. An anti-reverse locking mechanism, comprising an upper locking component 5 and a lower locking component 6, is used to prevent reverse locking after the connection of adjacent raise pipe bodies 1 is secure. These components work together to meet the high-intensity operational requirements of 10-meter diameter raise drilling, effectively solving the technical problems of easy deformation, threaded seizing, and easy reversal and loosening of existing raise pipes in large-diameter drilling.
[0040] Both the upper threaded connector 12 and the lower threaded connector 11 are made of high-strength alloy material, specifically chromium-molybdenum alloy steel. Their surfaces are coated with a wear-resistant coating with a thickness of 0.5-1mm. The wear-resistant coating is prepared by plasma spraying and the coating material is alumina ceramic, which can effectively improve the wear resistance and corrosion resistance of the threaded connector, extend the service life of the threaded connection, and meet the needs of frequent threaded connections and high-intensity rotation operations during 10-meter diameter raise boring.
[0041] The raise drill pipe body 1 is a hollow cylindrical structure designed to accommodate the load requirements of 10-meter diameter raise drills. Both the upper threaded connector 12 and the lower threaded connector 11 are made of high-strength alloy material with a wear-resistant coating on the surface. The raise drill pipe body 1 is integrally forged from high-strength alloy steel. Its outer diameter is designed to be 800-1000mm according to the load requirements of 10-meter diameter raise drills, and its wall thickness is 50-80mm. The hollow structure reduces the overall weight of the drill pipe and lowers the power consumption of the drilling equipment.
[0042] The rod reinforcement assembly 2 includes a reinforcement plate 21 and a fixing ring 22. The fixing ring 22 is sleeved on the surface of the raise drill pipe body 1. There are multiple fixing rings 22, which are evenly distributed along the axial direction of the raise drill pipe body 1. There are multiple reinforcement plates 21, which are evenly distributed along the circumference of the raise drill pipe body 1. The fixing ring 22 and the reinforcement plate 21 are welded together to enhance the deformation resistance and torque resistance of the raise drill pipe body 1, so as to cope with the complex stress borne by the drill pipe during the 10-meter diameter raise drilling process and avoid the bending and torsion deformation of the drill pipe.
[0043] The anti-biting agent addition mechanism 3 includes a replenishment shell 31, an annular connecting cavity 35, and a shell sealing cap 36. The replenishment shell 31 is fixedly sleeved on the outer surface of the upper threaded connector 12. The shell sealing cap 36 is sealed to the top of the replenishment shell 31 to seal the top of the replenishment shell 31. The inner side of the replenishment shell 31 communicates with the injection cavity 34 provided on the upper threaded connector 12. The end of the injection cavity 34 communicates with the annular connecting cavity 35 provided in the upper threaded connector 12. The inner side of the annular connecting cavity 35 is connected to a replenishment hole 37 provided on the upper threaded connector 12. The end of the replenishment hole 37 communicates with the inner cavity of the upper threaded connector 12.
[0044] In a specific embodiment, the sealing plug 33 of the injection hole 32 at the bottom of the supplementary shell 31 is opened, and sufficient anti-seize agent is injected into the inner cavity of the supplementary shell 31 through the injection hole 32. After injection, the sealing plug 33 is reinstalled to seal the supplementary shell 31. The anti-seize agent is stored in the inner cavity of the supplementary shell 31 to prepare for subsequent addition. At this time, the compression sealing ring 41 is in the initial position of the inner cavity of the supplementary shell 31 under the elastic force of the elastic spring 42. The elastic spring 42 is in a naturally extended state, and the telescopic rubber sleeve 43 wraps around the elastic spring 42 to play a protective role. When two adjacent raise pipe bodies 1 are connected, the upper threaded connector 12 of the lower raise pipe body 1 is aligned with the lower threaded connector 11 of the upper raise pipe body 1, and the upper raise pipe body 1 is rotated to perform threaded connection. As the threads are tightened, the locking lower component 6 of the upper drill pipe pushes the locking upper component 5 of the lower drill pipe downward. The locking seat 51 drives the extrusion column 44 to move downward. 44. The compression sealing ring 41 is pushed to slide downward along the inner cavity of the replenishing shell 31. The compression sealing ring 41 exerts a downward squeezing force on the anti-seize agent in the replenishing shell 31, forcing the anti-seize agent into the injection cavity 34 connected to the upper threaded connector 12 on the inner side of the replenishing shell 31. The anti-seize agent enters multiple annular connecting cavities 35 in the upper threaded connector 12 through the injection cavity 34. Since the annular connecting cavities 35 are equidistantly distributed along the axial direction of the upper threaded connector 12, and the height of the lowest annular connecting cavity 35 is higher than the top of the replenishing shell 31, it ensures that the anti-seize agent is evenly distributed in each annular connecting cavity 35. Subsequently, the anti-seize agent is stably and orderly delivered to the threaded connection part through the replenishment holes 37 distributed in annularly on the inner side of the annular connecting cavity 35, realizing simultaneous addition while connecting. The anti-seize agent fills the thread gap. In subsequent drilling operations, with the friction and heating of the threaded connection part, a uniform lubricating protective layer is formed, which effectively prevents thread seizing and jamming, and also plays a role in rust prevention.
[0045] The bottom surface of the supplementary shell 31 is provided with an injection hole 32 that communicates with the inner cavity of the supplementary shell 31. A detachable sealing plug 33 is provided in the injection hole 32 to seal the injection hole 32.
[0046] Multiple annular connecting cavities 35 are equidistantly distributed along the axial direction of the upper threaded connector 12. The lowest annular connecting cavity 35 is positioned at a height higher than the top of the supplementary shell 31. The annular connecting cavity 35 is used to connect the injection cavity 34 and the supplementary hole 37. Multiple annularly distributed supplementary holes 37 are connected to the inner side of the annular connecting cavity 35.
[0047] The extrusion linkage unit 4 is disposed between the upper threaded connector 12 and the supplementary shell 31. The extrusion linkage unit 4 includes an extrusion sealing ring 41, an elastic spring 42, a telescopic rubber sleeve 43, an extrusion column 44, and a guide sleeve 45. The extrusion sealing ring 41 is slidably connected to the inner cavity of the supplementary shell 31. The top of the extrusion sealing ring 41 is fixedly connected to the extrusion column 44. The top of the extrusion column 44 penetrates the top side of the shell sealing cover 36. The elastic spring 42 is sleeved on the surface of the extrusion column 44. The telescopic rubber sleeve 43 is sleeved on the surface of the elastic spring 42. The top of the extrusion column 44 is fixedly connected to the upper locking assembly 5. The top of the guide sleeve 45 is fixedly connected to the bottom of the upper locking assembly 5. The bottom of the guide sleeve 45 is slidably sleeved on the outer surface of the supplementary shell 31.
[0048] There are four extrusion columns 44, which are arranged in a ring on the top of the extrusion sealing ring 41. The extrusion sealing ring 41 is used to extrude the anti-seize agent in the extrusion filling shell 31 to the threaded connection of the adjacent raise drill pipe body 1.
[0049] The upper locking assembly 5 includes a locking seat 51, a first anti-reverse tooth 52, a locking pin 53, a locking spring 54, a connecting plate 55, a connecting block 56, and a rotating toothed ring 57. The locking seat 51 is fixedly connected to the top of the extrusion pin 44. The locking seat 51 is slidably sleeved on the surface of the upper threaded connector 12. Multiple first anti-reverse teeth 52 are evenly distributed in a ring on the top of the locking seat 51. The locking pin 53 is slidably connected in the sliding groove opened on the side surface of the first anti-reverse tooth 52. The locking pin 53 is elastically connected to the sliding groove through the locking spring 54. The outer side of the end of the locking pin 53 connected to the locking spring 54 is fixedly connected to the connecting plate 55. The end of the connecting plate 55 is fixedly connected to the connecting block 56. The connecting block 56 is fixedly connected to the inner wall of the rotating toothed ring 57.
[0050] Multiple connecting blocks 56 are distributed in a ring on the inner wall of the rotating toothed ring 57. The number of connecting blocks 56 is equal to the number of the first anti-reverse teeth 52. The connecting blocks 56 are slidably connected to the side surface of the corresponding first anti-reverse teeth 52.
[0051] The locking lower assembly 6 includes a locking plate 61, second anti-reverse teeth 62, and locking grooves 63. The locking plate 61 is fixedly sleeved on the bottom surface of the lower threaded connector 11. The locking plate 61 has an annular structure, and multiple second anti-reverse teeth 62 are fixedly connected to the bottom end of the locking plate 61, evenly distributed along the circumference of the locking plate 61. Locking grooves 63 are opened on the side surfaces of the second anti-reverse teeth 62. When adjacent raise boring machine bodies 1 are assembled, the second anti-reverse teeth 62 mesh with the corresponding first anti-reverse teeth 52, and the locking grooves 63 opened on the side surfaces of the second anti-reverse teeth 62 and the corresponding first anti-reverse teeth 52 mesh with each other. The locking pin 53 engages, and both the second anti-reverse tooth 62 and the first anti-reverse tooth 52 are helical tooth structures used to prevent the drill pipe body 1 from reversing and loosening during rotation. During drilling operations, the drill pipe is subjected to a continuous torsional torque. When a reversal tendency occurs, the helical tooth structures of the first anti-reverse tooth 52 and the second anti-reverse tooth 62 collide with each other, generating a reverse restraint force. At the same time, the engaging structure of the locking pin 53 and the locking groove 63 further restricts the separation of the two. The double protection achieves anti-reverse locking, ensuring that the drill pipe connection will not loosen due to reversal, and ensuring the stable operation of the 10-meter diameter raise drilling operation.
[0052] During use, when the threads of two adjacent raise pipe bodies 1 are tightened, the second anti-reverse tooth 62 at the bottom of the locking plate 61 in the lower locking assembly 6 of the upper raise pipe body 1 precisely meshes with the first anti-reverse tooth 52 at the top of the locking seat 51 in the upper locking assembly 5 of the lower pipe. Since both the first anti-reverse tooth 52 and the second anti-reverse tooth 62 are helical tooth structures, their tooth direction design matches the rotation direction of the drill pipe during drilling, which can limit the reverse tendency of the drill pipe. After the two raise pipe bodies 1 are fully threaded, the locking groove 63 on the side surface of the second anti-reverse tooth 62 and the locking post 53 on the side surface of the first anti-reverse tooth 52 are positioned. The locking post 53 is engaged in the locking groove 63 under the elastic action of the locking spring 54. At the same time, during the threaded connection tightening process, the subsequent anti-seize agent addition mechanism 3 will work synchronously. During subsequent disassembly, the connecting plate 55 and the locking pin 53 can be moved by rotating the rotating gear ring 57, which makes it easier to pull the locking pin 53 to compress the locking spring 54 and disengage it from the locking groove 63 when the drill pipe is disassembled, thus facilitating the subsequent disassembly of the raise drill pipe body 1.
