Description

Technical Field

[0001] This application relates to the field of drilling technology, and in particular to a directional drilling structure for navigable waterways and its application method. Background Technology

[0002] When laying heating pipes on the bottom of navigable waterways, large drilling equipment is required to drill along the riverbed. As the drilling equipment advances, the heating pipes are laid in close succession.

[0003] However, drilling equipment is prone to being obstructed by large clumps of silt or hard objects in the riverbed during the drilling process, which can cause the laying path of the heating pipeline to deviate from the original route. Summary of the Invention

[0004] To reduce the possibility of yaw during drilling, this application provides a directional drilling structure for navigable waterways and its application method.

[0005] Firstly, the directional drilling structure for navigable waterways provided in this application adopts the following technical solution:

[0006] A directional drilling structure for navigable waterways includes a drill bit body, an agitator rotatably connected to the end of the drill bit body, and a control component on the drill bit body for driving the agitator to rotate.

[0007] By adopting the above technical solution, when the drilling structure is installed on the drilling equipment for drilling, the control components drive the agitator to rotate. The agitator disperses the silt in front of the drilling equipment or breaks down hard objects in the riverbed in advance, thereby reducing the forward resistance of the drilling equipment and helping to reduce the phenomenon of yaw during the drilling equipment's movement in the riverbed.

[0008] Preferably, the agitator includes a connecting rod and an agitator sleeve. The connecting rod is rotatably connected to the end of the drill bit body, and the agitator sleeve is slidably connected to the connecting rod. The control component is used to drive the connecting rod to rotate. A locking component is provided on the connecting rod to fix the agitator sleeve to the connecting rod.

[0009] By adopting the above technical solution, the agitator sleeve is slidably connected to the connecting rod, and then the agitator sleeve is fixed to the connecting rod by the locking component, so as to realize the detachable connection between the connecting rod and the agitator sleeve. This makes it easy for staff to quickly and conveniently replace the agitator sleeve when the surface of the agitator sleeve is damaged or corroded after long-term use.

[0010] Preferably, the locking component includes an insert rod, an assist rod, and a locking block. The side wall of the connecting rod has a moving groove for the insert rod to slide. The inner wall of the agitator sleeve has a slot for the end of the insert rod to be inserted. The end of the connecting rod away from the drill bit body has an assist groove along its length for the assist rod to slide. The side walls of the insert rod and the assist rod abut against each other. The locking block is rotatably connected to the end wall of the assist rod. The end of the connecting rod has a locking thread groove for the locking block to be threaded into.

[0011] By adopting the above technical solution, the assist rod is moved along the length of the inner wall of the assist groove, so that the sliding of the assist rod drives the insertion rod to move along the length of the inner wall of the moving groove until the end of the insertion rod is inserted into the inner wall of the slot. Then, by rotating the locking block along the end of the assist rod until the locking block is threaded into the inner wall of the locking thread groove, the end of the insertion rod is stably fixed to the inner wall of the slot, and the agitator sleeve is then firmly fixed to the connecting rod.

[0012] Preferably, the side wall of the insertion rod is provided with a spring block, the inner wall of the moving groove is provided with a spring groove for the spring block to slide, the side wall of the spring block is provided with an elastic element, and the end of the elastic element away from the spring block is provided on the inner wall of the spring groove.

[0013] By adopting the above technical solution, when the staff replaces the agitator sleeve, the end of the assist rod is disengaged from the abutment of the insertion rod. At this time, the rebound block is subjected to the elastic force of the elastic element and rebounds along the length direction of the inner wall of the rebound groove. The rebound block drives the insertion rod to move along the length direction of the inner wall of the moving groove, thereby quickly and conveniently disengaging the end of the insertion rod from the inner wall of the slot, thus facilitating the staff to quickly and conveniently replace the agitator sleeve.

[0014] Preferably, the drill bit body is rotatably connected to an installation ring, the installation ring is provided with a plurality of pushing members, each of the pushing members including a pressing rod and an auxiliary block, the drill bit body is provided with a sliding hole for the corresponding pressing rod to slide, the auxiliary block is provided on the side wall of the pressing rod, the installation ring is provided with an auxiliary hole for the corresponding auxiliary block to slide, and the drill bit body is provided with a rotating assembly, the rotating assembly being used to drive the installation ring to reciprocate along the drill bit body.

[0015] By adopting the above technical solution, the rotating component drives the mounting ring to reciprocate, so that the auxiliary block reciprocates along the length of the inner wall of the corresponding auxiliary hole, thereby driving the extrusion rod to reciprocate along the length of the inner wall of the corresponding sliding hole. This allows several extrusion rods to extrude the dispersed silt during drilling, thereby reducing the possibility of backfilling after the dispersed silt and improving the stability of the drilling process.

[0016] Preferably, the rotating assembly includes a rotating motor, a rotating gear ring, a support rod, a support gear, a rotating rack, a rotating ring, a linkage gear, a linkage gear ring strip, and a driving component. The drill bit body has an internal receiving cavity. The rotating motor is disposed on the inner wall of the receiving cavity. The rotating gear ring is disposed at the output end of the rotating motor. The support rod is rotatably connected to the inner wall of the receiving cavity. The support gear is disposed on the side wall of the support rod. The rotating rack is disposed on the side wall of the rotating ring. The rotating ring is rotatably connected to the drill bit body. The rotating gear ring and rotating rack alternately mesh with the support gear. The linkage gear is disposed on the side wall of the support rod. The linkage gear ring strip is disposed on the inner wall of the mounting ring. The linkage gear and linkage gear ring strip mesh with each other. The driving component drives the rotating gear ring and rotating rack to rotate in the same direction.

[0017] By adopting the above technical solution, the rotating motor drives the rotating gear ring to rotate. When the rotating gear ring meshes with the support gear, the support rod rotates. The support rod drives the mounting ring to rotate through the linkage gear and the linkage gear ring. At this time, the driving component drives the rotating rack to rotate so that the rotating rack and the support gear do not mesh. When the rotating gear ring continues to rotate until it does not mesh with the support gear, the driving component drives the rotating rack to rotate so that the rotating rack meshes with the support gear, thereby driving the support rod to rotate in the direction of rotation. The support rod drives the mounting ring to rotate in the direction of rotation through the linkage gear and the linkage gear ring, so as to realize the reciprocating rotation of the mounting ring, thereby realizing the reciprocating movement of the extrusion rod along the length direction of the inner wall of the corresponding sliding hole.

[0018] Preferably, the driving component includes two driving gears and a driving gear ring. One driving gear is disposed on the side wall of the rotating motor, and the other driving gear is disposed on the side wall of the support rod. The two driving gears mesh with each other. The driving gear ring is disposed on the side wall of the rotating ring and meshes with the driving gear that is close to it.

[0019] By adopting the above technical solution, when the rotating motor drives the connected drive gear to rotate, the drive gear drives another drive gear to rotate in the opposite direction, and the other drive gear drives the drive gear rack to rotate in the opposite direction, so that the rotating gear ring and the rotating ring rotate in the same direction, and thus the rotating gear ring and the rotating gear rack rotate in the same direction.

[0020] Preferably, the drill bit body includes a first drill rod and a second drill rod, the first drill rod being rotatably connected to the second drill rod, the connecting rod being rotatably connected to the end of the first drill rod away from the second drill rod, the control component being disposed on the first drill rod, the mounting ring being rotatably connected to the first drill rod, a plurality of sliding holes being formed on the first drill rod, the receiving cavity being formed on the first drill rod, and a stabilizing component being disposed on the second drill rod, the stabilizing component being used to drive the first drill rod to rotate.

[0021] By adopting the above technical solution, the second drill rod is fixed to the drilling equipment, and the first drill rod is rotated by a stabilizing component. Thus, when the extrusion rod reciprocates along the length of the corresponding sliding hole inner wall, the first drill rod rotates simultaneously. This effectively expands the extrusion range of the multiple extrusion rods on the dispersed silt, further reducing the possibility of backfilling after the dispersed silt. This further improves the stability of the drill press structure installed on the drilling equipment during the drilling process.

[0022] Preferably, the stabilizing component includes a stabilizing motor, a fixing cavity is formed on the second drill rod, the stabilizing motor is disposed on the inner wall of the fixing cavity, the output end of the stabilizing motor is connected to the first drill rod, and the control component includes a docking rod, a first connecting gear, a second connecting gear, and two docking gears. A placement cavity is formed inside the first drill rod, the docking rod is rotatably connected to the inner wall of the placement cavity, the first connecting gear is disposed on the output end of the stabilizing motor, the second connecting gear is disposed on the side wall of the connecting rod, and the two docking gears are symmetrically disposed at both ends of the docking rod. The first connecting gear meshes with the docking gears that are close to each other, and the second connecting gear meshes with the docking gears that are close to each other.

[0023] By adopting the above technical solution, when the stabilizing motor drives the first drill rod to rotate, the stabilizing motor drives the docking rod to rotate through the first connecting gear and the docking gear. The docking rod then drives the connecting rod to rotate through the second connecting gear and the docking gear, thereby effectively saving energy consumption and achieving energy conservation and emission reduction.

[0024] On the other hand, the application method for a directional drilling structure in a navigable waterway, as described in the first aspect, adopts the following technical solution:

[0025] A method for applying a directional drilling structure in a navigable waterway includes the following steps:

[0026] The control unit drives the agitator to rotate, thereby dispersing the silt in front of the drilling equipment or breaking up hard objects in the riverbed in advance, thus reducing the forward resistance encountered by the drilling equipment during the drilling process.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. When the drilling structure is installed on the drilling equipment for drilling, the control components drive the agitator to rotate. The agitator disperses the silt in front of the drilling equipment or breaks up hard objects in the riverbed in advance, thereby reducing the forward resistance of the drilling equipment and helping to reduce the phenomenon of yaw during the drilling equipment's movement in the riverbed.

[0029] 2. The rotating component drives the mounting ring to reciprocate, causing the auxiliary block to reciprocate along the length of the inner wall of the corresponding auxiliary hole. This, in turn, causes the extrusion rod to reciprocate along the length of the inner wall of the corresponding sliding hole. As a result, when the drilling equipment is drilling, several extrusion rods extrude the dispersed silt, thereby reducing the possibility of backfilling after the dispersed silt and improving the stability of the drilling machine structure during the drilling process.

[0037] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0038] Example 1

[0039] Embodiment 1 of this application discloses a directional drilling structure for navigable waterways. (Refer to...) Figure 1 and Figure 2 The drilling structure includes a drill bit body 1, with a stirring frame 2 at one end of the drill bit body 1. A control component 3 is also provided on the drill bit body 1, which drives the stirring frame 2 to rotate. When the drilling structure is installed on the drilling equipment and drilling is carried out along the riverbed, the control component 3 drives the stirring frame 2 to rotate, so that the stirring frame 2 disperses the silt in front of the drilling equipment or breaks down hard objects in the riverbed in advance. This reduces the forward resistance encountered by the drilling equipment during drilling along the riverbed, and helps to reduce the phenomenon of yaw during the drilling equipment's movement along the riverbed.

[0040] Reference Figure 2 and Figure 3 The agitator 2 includes a connecting rod 21 and an agitator sleeve 22. The connecting rod 21 is rotatably connected to the drill bit body 1 through a bearing seat, and the agitator sleeve 22 is slidably connected to the connecting rod 21. The control component 3 is used to drive the connecting rod 21 to rotate. A locking element 4 is provided on the connecting rod 21. The locking element 4 includes an insert rod 41, an assist rod 42, and a locking block 43. In embodiment 1 of this application, there are two insert rods 41, which are symmetrically arranged. The side wall of the connecting rod 21 is provided with a moving groove 211 for the corresponding insert rod 41 to slide. The inner wall of the agitator sleeve 22 is provided with a slot 221 for the end of the corresponding insert rod 41 to be inserted. The end of the connecting rod 21 away from the drill bit body 1 is provided with an assist groove 212 for the assist rod 42 to slide along the length direction. The end walls of the two insert rods 41 are in contact with the side wall of the assist rod 42. The locking block 43 is rotatably connected to the end of the assist rod 42 away from the drill bit body 1 through a bearing seat. The end of the connecting rod 21 is provided with a locking thread groove 213 for the locking block 43 to be threaded. The locking block 43 has an embedding groove 214 on the side near the assist rod 42. The inner wall of the embedding groove 214 is glued with a first sealing ring 2141. The first sealing ring 2141 abuts against the inner wall of the locking thread groove 213. In Embodiment 1 of this application, the first sealing ring 2141 is made of rubber, thereby improving the sealing performance of the assist rod 42 embedded in the inner wall of the assist groove 212.

[0041] Reference Figure 4 The inner wall of the agitator sleeve 22 is provided with an abutment groove 222. The inner wall of the abutment groove 222 is glued with a second sealing ring 2221. In Embodiment 1 of this application, the second sealing ring 2221 is made of rubber. When the agitator sleeve 22 is fixed to the side wall of the connecting rod 21 by the locking member 4, the second sealing ring 2221 abuts against the connecting rod 21, which effectively improves the sealing between the agitator sleeve 22 and the connecting rod 21.

[0042] Reference Figure 4 Both insert rods 41 have rebound blocks 411 welded to their side walls. The inner wall of the moving groove 211 is provided with a rebound groove 215 along its length for the rebound blocks 411 to slide. An elastic element 4111 is welded to the side wall of the rebound blocks 411. The end of the elastic element 4111 away from the rebound blocks 411 is welded to the inner wall of the rebound groove 215. In Embodiment 1 of this application, the elastic element 4111 is a spring.

[0043] Reference Figure 2 , Figure 3 and Figure 4 When the surface of the agitator sleeve 22 is damaged or corroded after long-term use, the locking block 43 is rotated along the inner wall of the locking thread groove 213, causing the locking block 43 to disengage from the inner wall of the locking thread groove 213; then the assist rod 42 is slid along the length of the inner wall of the assist groove 212 until the assist rod 42 is completely disengaged from the inner wall of the assist groove 212. At this time, the spring block 411 moves along the length of the inner wall of the corresponding spring groove 215 under the action of the elastic force of the elastic element 4111, so that the spring block 41 drives the corresponding insertion rod 41 to move along the length of the inner wall of the corresponding moving groove 211, so that the end of the insertion rod 41 quickly disengages from the inner wall of the corresponding slot 221, thereby facilitating the workers to quickly and conveniently disengage the agitator sleeve 22 from the side wall of the connecting rod 21, thereby improving the efficiency of the workers in replacing the agitator sleeve 22.

[0044] Reference Figure 2 The drill bit body 1 includes a first drill rod 11 and a second drill rod 12. The first drill rod 11 is rotatably connected to the second drill rod 12 through a bearing seat. The connecting rod 21 is rotatably connected to the end of the first drill rod 11 away from the second drill rod 12 through a bearing seat. A stabilizing member 8 is provided on the second drill rod 12. The stabilizing member 8 is used to drive the first drill rod 11 to rotate.

[0045] Reference Figure 2The stabilizing component 8 includes a stabilizing motor 81. A fixed cavity 121 is formed on the second drill rod 12. The stabilizing motor 81 is bolted to the inner wall of the fixed cavity 121. The output end of the stabilizing motor 81 is connected to the first drill rod 11. The control component 3 includes a docking rod 31, a first connecting gear 32, a second connecting gear 33, and two docking gears 34. A placement cavity 113 is formed inside the first drill rod 11 along its length. The docking rod 31 is rotatably connected to the inner wall of the placement cavity 113 through a bearing seat. The output end of the stabilizing motor 81 and the end of the connecting rod 21 both extend into the placement cavity 113. The first connecting gear 32 is welded to the output end of the stabilizing motor 81. The second connecting gear 33 is welded to the side wall of the connecting rod 21. The two docking gears 34 are symmetrically welded to both ends of the docking rod 31. The first connecting gear 32 meshes with the docking gear 34 that is close to it, and the second connecting gear 33 meshes with the docking gear 34 that is close to it.

[0046] Reference Figure 2 When the stabilizing motor 81 starts, causing the first drill rod 11 to rotate, the stabilizing motor 81 drives the connected first connecting gear 32 to rotate, the first connecting gear 32 drives the connected docking gear 34 to rotate, so that the docking rod 31 rotates, thereby driving the other docking gear 34 to rotate, and the other docking gear 34 drives the connecting rod 21 to rotate through the meshing second connecting gear 33, so that the agitator sleeve 22 rotates through the connecting rod 21.

[0047] Reference Figure 2 A mounting ring 5 is rotatably connected to the first drill rod 11 via a bearing seat. Several pushing members 6 are evenly arranged on the mounting ring 5. In embodiment 1 of this application, four pushing members 6 are provided. Each of the four pushing members 6 includes a pressing rod 61 and an auxiliary block 62. A sliding hole 111 is provided on the first drill rod 11 for the corresponding pressing rod 61 to slide. The auxiliary block 62 is welded to the side wall of the pressing rod 61. An auxiliary hole 51 is provided on the mounting ring 5 for the corresponding auxiliary block 62 to slide. A limiting block 621 is integrally formed at the end of the auxiliary block 62 away from the pressing rod 61. The limiting block 621 moves along the mounting ring 5.

[0048] Reference Figure 2 A rotating assembly 7 is provided on the first drill rod 11. The rotating assembly 7 is used to drive the mounting ring 5 to reciprocate along the first drill rod 11. The rotating assembly 7 includes a rotating motor 71, a rotating gear ring 72, a support rod 73, a support gear 74, a rotating rack 75, a rotating ring 76, a linkage gear 77, a linkage gear ring 78, and a driving component 79.

[0049] Reference Figure 2 and Figure 5The first drill rod 11 has an internal cavity 112. The rotating motor 71 is bolted to the inner wall of the cavity 112. The rotating gear ring 72 is welded to the output end of the rotating motor 71. The support rod 73 is rotatably connected to the inner wall of the cavity 112 through a bearing seat. The support gear 74 is welded to the side wall of the support rod 73. The rotating rack 75 is welded to the side wall of the rotating ring 76. The rotating ring 76 is rotatably connected to the first drill rod 11 through a bearing seat. The rotating gear ring 72 and the rotating rack 75 alternately mesh with the support gear 74. The linkage gear 77 is welded to the side wall of the support rod 73. The linkage gear ring 78 is welded to the side of the mounting ring 5 near the first drill rod 11. The linkage gear 77 and the linkage gear ring 78 mesh with each other. The driving component 79 is used to drive the rotating gear ring 72 and the rotating rack 75 to rotate in the same direction.

[0050] Reference Figure 2 The drive component 79 includes two drive gears 791 and a drive gear ring 792. One drive gear 791 is welded to the output end of the rotating motor 71, and the other drive gear 791 is welded to the side wall of the support rod 73. The two drive gears 791 mesh with each other. The drive gear ring 792 is welded to the side wall of the rotating ring 76 and meshes with the drive gear 791 that is close to it.

[0051] Reference Figure 2 and Figure 5 When the rotating motor 71 is started, the connected drive gear 791 is driven to rotate. The drive gear 791 drives another drive gear 791 to rotate in the opposite direction. The other drive gear 792 drives the drive gear ring 792 to rotate in the opposite direction, so that the rotating gear ring 72 and the rotating ring 76 rotate in the same direction, and thus the rotating gear ring 72 and the rotating rack 75 rotate in the same direction. The rotating motor 71 drives the rotating gear ring 72 to rotate. When the rotating gear ring 72 meshes with the support gear 74, the support rod 73 rotates. The support rod 73 drives the mounting ring 5 to rotate through the linkage gear 77 and the linkage gear ring 78. At this time, the rotating ring 76 drives the rotating rack 75 to rotate, so that the rotating rack 75 and the support gear 74 do not mesh with each other.

[0052] Reference Figure 2 and Figure 5 When the rotating gear ring 72 continues to rotate until it is no longer engaged with the support gear 74, the rotating ring 76 drives the rotating rack 75 to rotate, so that the rotating rack 75 engages with the support gear 74, thereby driving the support rod 73 to rotate in the opposite direction. The support rod 73 drives the mounting ring 5 to rotate in the opposite direction through the linkage gear 77 and the linkage gear ring 78, so as to realize the reciprocating rotation of the mounting ring 5.

[0053] Reference Figure 2 and Figure 5The reciprocating rotation of the mounting ring 5 causes the extrusion rod 61 to reciprocate along the length of the inner wall of the corresponding sliding hole 111. This extrusion rod 61 then compresses the dispersed silt, reducing the likelihood of backfilling and effectively improving the stability of the drilling equipment during drilling along the riverbed. Furthermore, during the reciprocating rotation of the mounting ring 5, the first drill rod 11 continuously rotates, expanding the compression range of the extrusion rods 61 on the dispersed silt, further reducing the possibility of backfilling.

[0054] Embodiment 1 of this application discloses the implementation principle of a directional drilling structure for navigable waterways: when the drilling structure is installed on the drilling equipment and drilling is carried out along the riverbed, the stabilizing motor 81 is started. The stabilizing motor 81 drives the connected first connecting gear 32 to rotate, and the first connecting gear 32 drives the connected docking gear 34 to rotate, so that the docking rod 31 rotates, thereby driving the other docking gear 34 to rotate. The other docking gear 34 drives the connecting rod 21 to rotate through the meshing second connecting gear 33. The connecting rod 21 drives the agitator sleeve 22 to rotate, thereby dispersing the silt in front of the drilling equipment or breaking the hard objects in the riverbed in advance through the agitator sleeve 22, reducing the forward resistance of the drilling equipment, and thus reducing the phenomenon of yaw during the forward movement of the drilling equipment.

[0055] Example 2

[0056] This application, in embodiment 2, discloses a method for applying the directional drilling structure of a navigable waterway as described in embodiment 1, comprising the following steps:

[0057] S1. When the drilling structure is installed on the drilling equipment for drilling, the stabilizing motor 81 is started, causing the first drill rod 11 to rotate. The stabilizing motor 81 drives the connected first connecting gear 32 to rotate. The first connecting gear 32 drives the connecting rod 31 to rotate through the meshing docking gear 34, thereby driving the other docking gear 34 to rotate. The other docking gear 34 drives the connecting rod 21 to rotate through the meshing second connecting gear 33. The connecting rod 21 drives the agitating sleeve 22 to rotate, thereby dispersing the silt in front of the drilling equipment through the agitating sleeve 22, or breaking the hard objects in the riverbed in advance, so as to reduce the forward resistance of the drilling equipment body.

[0058] S2. When the stabilizing motor 81 starts, the first drill rod 11 rotates simultaneously; at this time, the rotating motor 71 starts, and the rotating motor 71 drives the driving gear rack 792 to rotate in opposite directions through the two driving gears 791, thereby causing the rotating gear ring 72 and the rotating ring 76 to rotate in the same direction, and thus causing the rotating gear ring 72 and the rotating rack 75 to rotate in the same direction; and the rotating motor 71 drives the rotating gear ring 72 to rotate. When the rotating gear ring 72 meshes with the support gear 74, the support rod 73 rotates. The support rod 73 drives the mounting ring 5 to rotate through the linkage gear 77 and the linkage gear rack 78. At this time, the rotating ring 76 drives the rotating rack 75 to rotate. 5. The rotating ring 72 is not meshed with the support gear 74. When the rotating ring 72 continues to rotate until it is not meshed with the support gear 74, the rotating ring 76 drives the rotating rack 75 to rotate, so that the rotating rack 75 meshes with the support gear 74, thereby driving the support rod 73 to rotate in the opposite direction. The support rod 73 drives the mounting ring 5 to rotate in the direction of the linkage gear 77 and the linkage ring 78, so as to realize the reciprocating rotation of the mounting ring 5. This enables the extrusion rod 61 to reciprocate along the length direction of the inner wall of the corresponding sliding hole 111, and then extrudes the dispersed sludge through the extrusion rod 61, reducing the possibility of the dispersed sludge being backfilled, and effectively improving the stability of the drilling equipment during the drilling process.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
