Description

TECHNICAL FIELD

[0002] The joint of oil drill pipe is a very key part in drill string system, which is responsible for connecting single drill pipe and transmitting torque, bearing tensile and compressive load as well as internal high pressure drilling fluid. Its structure generally includes two types, traditional eye drill pipe and joint welding structure and modern integral drill pipe structure. At present, most of the oil drill pipes adopt integral drill pipe structure, that is, drill pipe body and joint are processed from an integral forging, or the joint and pipe body are friction welded and then processed integrally, so that the joint thread part and pipe body become a smooth transition as a whole.

[0003] When turning the joint of oil drill pipe, the drill pipe structure is generally positioned by positioning structure, then the positioning structure and drill pipe structure are driven to rotate simultaneously, and during rotation, turning tool is used for turning processing.

[0004] For example, a kind of oil drill pipe joint turning equipment with patent publication number CN118616742B, its structure mainly includes shell and multiple first clamping blocks, also includes supporting device, pushing device, cutter assembly and second clamping block, supporting device is used to drive shell to rotate and drive multiple first clamping blocks to move, pushing device is used to drive two groups of second clamping blocks to move adjustment; one end of the joint is positioned by multiple first clamping blocks, and the shell and first clamping blocks drive the joint to rotate by supporting device, and then cutting processing is carried out by cutter assembly.

[0005] The above device can realize the positioning, rotation and turning processing of drill pipe joint, but when positioning, only the end of the joint can be positioned, and for long joint structure or integral drill pipe structure, the positioning operation is not convenient, and the positioning effect is poor, which reduces the stability of positioning and affects the effect and precision of turning processing.

[0057] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0058] Example 1: Please refer to the accompanying drawings. This invention provides a technical solution:

[0059] A type of oil drill pipe joint turning equipment, such as Figure 1 As shown, it includes a base 100, and a dual-station turning mechanism is provided at one end of the top of the base 100.

[0060] The top of the base 100 is provided with a fixed seat 102. The bottom of the dual-station turning mechanism is slidably connected to the top surface of the base 100 and connected to one end of the fixed seat 102 through the first hydraulic rod 106. The top of the base 100 is provided with a movable seat 101 on the side away from the dual-station turning mechanism, and the movable seat 101 and the fixed seat 102 are connected by a movable structure.

[0061] The movable structure includes two first screws 103 arranged symmetrically and in parallel. One end of the first screw 103 is rotatably connected to the fixed base 102, and the other end is rotatably connected to the end of the base 100 and connected to a motor. The two first screws 103 are respectively threaded to both sides of the movable base 101.

[0062] like Figure 1 As shown, both the movable base 101 and the fixed base 102 have two symmetrical and vertical mounting plates 303 fixed to their tops, as... Figure 5 As shown, a rotating assembly is provided between the tops of the two mounting plates 303, and a conveying assembly is provided on the opposite sides of the two rotating assemblies. A first rotating plate 300 and a second rotating plate 301 are symmetrically fixed on the rotating assembly, and six positioning mechanisms are evenly provided between the first rotating plate 300 and the second rotating plate 301 along the circumferential direction.

[0063] like Figure 6 As shown, the positioning mechanism includes two parallel first limiting wheels 306 rotatably connected between the first rotating plate 300 and the second rotating plate 301. An L-shaped limiting frame 600 is provided on one side of each first limiting wheel 306. Two parallel second limiting wheels 601 are rotatably connected to the outer end of the limiting frame 600 at corresponding positions. A moving component is connected to the inner end of the limiting frame 600, such as... Figure 12 As shown, one end of the moving component extends out of the second rotating plate 301 and is connected to an adjustment component accordingly;

[0064] One end of the first limiting wheel 306 extends out of the first rotating plate 300 and is connected with a transmission structure, the inside of the transmission structure is provided with a limiting assembly, and the lower side of the transmission structure is provided with a lifting driving structure;

[0065] As shown in Figure 8 The first rotating plate 300 and the second rotating plate 301 are rotationally connected with two parallel guide wheels 307 corresponding to the position of each limiting frame 600, and the inner side of the limiting frame 600 is located between the two guide wheels 307, which provides limiting guidance and support for the limiting frame 600 when it moves, making the position more stable.

[0066] When turning the oil drilling rod joint, the oil drilling rod is loaded from one side of the two conveying assemblies and moves intermittently, so that the oil drilling rod approaches the rotating assembly in turn, wherein six positioning mechanisms are arranged on the rotating assembly, and the middle two sides of the rotating assembly are respectively arranged as a loading position and a discharging position, the upper two sides are a first machining position and a second machining position, and the bottom two sides are an idle position; when the rotating assembly switches the positions of the multiple positioning mechanisms, the positioning mechanisms pass through the idle position, the loading position, the first machining position, the second machining position and the discharging position in turn;

[0067] When the oil drilling rod on the conveying assembly approaches the loading position, the positioning mechanism is rotated from the idle position to the loading position through the rotating assembly, so that the oil drilling rod is located inside the L-shaped limiting frame 600 and between the first limiting wheel 306 and the second limiting wheel 601;

[0068] The adjusting assembly is started, the adjusting assembly is connected with the moving assembly of the loading position and the discharging position, so as to drive the moving assembly to move and adjust the movement of the limiting frame 600 and the second limiting wheel 601; the second limiting wheel 601 of the loading position approaches the first limiting wheel 306, so that the oil drilling rod is clamped through the joint action of the two first limiting wheels 306 and the two second limiting wheels 601, and the two positioning mechanisms are used to position the two side sections of the oil drilling rod.

[0069] After the oil drilling rod is positioned, the positions of the multiple positioning mechanisms are switched through the rotating assembly, so that the positioning mechanism drives the oil drilling rod to move from the loading position to the first machining position for turning the outer wall of the drilling rod joint, and then moves from the first machining position to the second machining position for turning the inner wall of the drilling rod joint; during the machining of the two sides, the first limiting wheel 306 is rotated through the connection of the lifting driving structure and the transmission structure, and the oil drilling rod is driven to rotate, so as to cooperate with the double-station turning mechanism during the rotation of the drilling rod, and the turning of the inner wall and the outer wall of the joint is carried out.

[0070] After two turning processes are completed, the rotating assembly is rotated again, the oil drill rod is moved from the second processing position to the discharging position, the limiting frame 600 drives the second limiting wheel 601 to move outward through the action of the adjusting assembly and the moving assembly, the positioning of the oil drill rod is cancelled, and thus the processed oil drill rod falls on the conveying assembly and is conveyed outward along with the conveying assembly, the position of the positioning mechanism is staggered, and the positioning mechanism can continue to move to the empty position.

[0071] When the rotating assembly needs to rotate and switch the positions of multiple positioning mechanisms, the limiting assembly limits the position of the transmission structure, so that the transmission structure remains relatively fixed with the first rotating plate 300, then the lifting driving structure is separated from the transmission structure, and the rotation of the transmission structure along with the first rotating plate 300 and other structures is avoided.

[0072] The oil drill rod is conveyed by the conveying assembly, and cooperates with the rotating assembly and the six positioning mechanisms, so that the oil drill rod can pass through the feeding position, the first processing position, the second processing position and the discharging position in sequence, and the feeding and positioning of the oil drill rod, the turning processing of the outer wall and the inner wall of the drill rod joint and the discharging operation are sequentially performed, and the continuous processing of the oil drill rod is realized.

[0073] The oil drill rod structure can be turned on the outer wall and the inner wall, the processing is more comprehensive, and the feeding, positioning and other operations do not need to be performed again, so that the processing is faster, more convenient and fast.

[0074] The oil drill rod structure can be turned on the outer wall and the inner wall, the processing is more comprehensive, and the feeding, positioning and other operations do not need to be performed again, so that the processing is faster, more convenient and fast.

[0075] Among them, for example, Figure 13As shown, the moving assembly comprises a rectangular frame 603 fixed between the first rotating plate 300 and the second rotating plate 301, the inner side end of the limiting frame 600 is fixed with an adjusting seat 602, the adjusting seat 602 is slidingly connected in the rectangular frame 603, two second screws 604 are rotatably connected in the rectangular frame 603, the adjusting seat 602 is threadedly connected with the second screws 604, the bottom of the second screw 604 is fixed with a first gear 605, one side of the first gear 605 is engaged with a second gear 606, the two second gears 606 are located between the two first gears 605 and are engaged with each other, one of the second gears 606 is coaxially fixed with a third bevel gear 607, the third bevel gear 607 is located on the outer side of the rectangular frame 603 and is engaged with a fourth bevel gear 608, the center of the fourth bevel gear 608 is fixed with an adjusting rotating shaft 609, the adjusting rotating shaft 609 is rotatably connected with the second rotating plate 301, one end of the adjusting rotating shaft 609 extends out of the second rotating plate 301 and is fixed with an adjusting gear 610, and the adjusting gear 610 is correspondingly connected with the adjusting assembly.

[0076] When it is necessary to adjust the positions of the limiting frame 600 and the second limiting wheel 601, the adjusting assembly is used to drive the adjusting gear 610 to rotate the adjusting rotating shaft 609 and the fourth bevel gear 608, and then the third bevel gear 607 and the fourth bevel gear 608 are driven, the first gear 605 and the second gear 606 are driven, the two second screws 604 are simultaneously rotated, and the positions of the adjusting seat 602, the limiting frame 600 and the second limiting wheel 601 are driven, so that the positioning operation and the de-positioning operation of the petroleum drill pipe are realized.

[0077] As shown in the drawings, Figure 12 , Figure 14 As shown, the adjusting assembly comprises a supporting frame 700, the bottom end of the supporting frame 700 is fixedly connected with the moving seat 101 and the top of the fixed seat 102 in the corresponding position, the upper part of the supporting frame 700 is inclined, two adjusting hydraulic rods 701 are symmetrically arranged on the inclined section of the supporting frame 700, the top end of the adjusting hydraulic rod 701 extends out of the supporting frame 700 and is fixed with a sliding groove 702, a telescopic block 705 is connected in the sliding groove 702 through a telescopic hydraulic rod 704, the adjusting rack 706 is fixed on the side of the telescopic block 705 close to the second rotating plate 301, and the adjusting rack 706 is arranged perpendicularly to the inclined section of the supporting frame 700 and symmetrically on the two sides of the rotating cylinder 302.

[0078] The two sliding grooves 702 are commonly fixed with a giving-way connecting frame 703, the giving-way connecting frame 703 slides through the middle of the inclined section of the supporting frame 700, the rotating cylinder 302 in the center of the rotating assembly is located in the giving-way connecting frame 703, so that the movement of the sliding groove 702 and other structures is not affected by the rotating cylinder 302, and the structural stability of the inner side end of the two sliding grooves 702 is improved by arranging the giving-way connecting frame 703 between the two sliding grooves 702.

[0079] When the oil drill rod needs to be fed and discharged, two inclined adjusting racks 706 are respectively located outside the two adjusting gears 610 in the corresponding positions, the telescopic block 705 drives the adjusting rack 706 to move through the telescopic hydraulic rod 704, and is engaged with the corresponding adjusting gear 610, then the sliding groove 702, the telescopic block 705 and the adjusting rack 706 are moved through the adjusting hydraulic rod 701, the adjusting gear 610 is driven to rotate, and then the moving assembly is driven to work, the position of the second limiting wheel 601 relative to the first limiting wheel 306 is adjusted, the oil drill rod feeding positioning and discharging operation are realized.

[0080] As shown in Figure 5 , the rotating assembly comprises a horizontal rotating cylinder 302 rotatably connected between the top portions of the two mounting plates 303, the first rotating plate 300 and the second rotating plate 301 are located between the two mounting plates 303 and are symmetrically fixed to the rotating cylinder 302, the two ends of the rotating cylinder 302 extend out of the mounting plates 303, one end of the rotating cylinder 302 is fixed with a driving bevel gear 304, the bottom of the driving bevel gear 304 is engaged with a driven bevel gear 305, the driven bevel gear 305 is connected with a motor, and the motor is connected with the mounting plate 303.

[0081] When the positions of multiple positioning mechanisms need to be switched, the rotating cylinder 302 drives the first rotating plate 300 and the second rotating plate 301 to rotate through the driving of the motor and the transmission of the driving bevel gear 305 and the driven bevel gear 304, and the positions of multiple positioning mechanisms are switched in sequence by rotating the same angle each time.

[0082] In the second embodiment, the structure of the second embodiment is basically the same as that of the first embodiment, and the difference lies in that, as shown in Figure 9 , the transmission structure comprises an annular boss 400 fixed to the outside of the first rotating plate 300, the outside of the annular boss 400 is rotatably connected with a rotating gear 401, the bottom of the rotating gear 308 is connected with the lifting driving structure, one end of the first limiting wheel 306 extends out of the first rotating plate 300 and is fixed with the rotating gear 308, and the multiple rotating gears 308 are engaged with the rotating gear 401;

[0083] As shown in Figure 11 , the lifting driving structure comprises a lifting gear 309 located below the rotating gear 401, the lifting gear 309 is connected with a motor, and the bottom of the motor is provided with a lifting plate 310, the bottom of the lifting plate 310 is connected with the top of the moving seat 101 and the fixed seat 102 in the corresponding position through a lifting hydraulic rod 311.

[0084] When the first limit wheel 306 needs to rotate, the lifting plate 310 is driven by the lifting hydraulic rod 311 to move the lifting gear 309 upward. The lifting gear 309 meshes with the bottom of the rotating gear ring 401. Through the drive of the motor and the transmission between the lifting gear 309 and the rotating gear 308, multiple rotating gears 308 are driven to rotate synchronously, thereby causing the first limit wheel 306 to rotate and the corresponding oil drill pipe to rotate for corresponding turning operations.

[0085] When rotation is not required, the motor of the lifting gear 309 stops driving, and the position of the rotating gear ring 401 is restricted by the limit component so that it cannot rotate at will. Then the lifting hydraulic rod 311 and the lifting plate 310 drive the lifting gear 309 to move down and disengage from the rotating gear ring 401, so as to avoid affecting the rotation of the first rotating plate 300 and its positioning mechanism.

[0086] Example 3: The structure of this example is basically the same as that of Example 2, except that, as shown in Example 3... Figure 9 , Figure 10 As shown, the limiting component includes slots evenly arranged in the annular boss 400 along the circumferential direction, and a locking block 402 is provided in the slot. A spring seat 404 is provided on the outer side of the first rotating plate 300 corresponding to the position of each locking block 402. A spring is connected between the spring seat 404 and the locking block 402. Two parallel spring rods 403 are symmetrically fixed on the locking block 402. One end of the two spring rods 403 passes through the spring seat 404 and is fixed together with a push block 405. The end of the push block 405 is provided with an inclined surface.

[0087] A movable cylinder 503 is provided at the center of the outer side of the first rotating plate 300. An annular rotating pressure plate 500 is rotatably connected to the inner end of the movable cylinder 503. Multiple extrusion blocks 504 are evenly fixed on the rotating pressure plate 500 along the circumferential direction. Figure 7 As shown, the end of the extrusion block 504 is provided with an inclined surface, and the inclined surface contacts the inclined surface of the push block 405 at the corresponding position. Two end plates 502 are symmetrically fixed on the outer end of the moving cylinder 503, and the end plates 502 are connected to the mounting plate 303 on the corresponding side through the limiting hydraulic rod 501.

[0088] When it is required to fix the position of the rotating gear ring 401, the limiting hydraulic rod 501 drives the end plate 502, the moving cylinder 503 and the rotating pressure plate 500 to move towards the first rotating plate 300, and the extrusion block 504 extrudes the pushing block 405 through the inclined surface, so that the pushing block 405 drives the spring rod 403 and the clamping block 402 to move outward, the end of the clamping block 402 penetrates through the clamping slot on the annular boss 400, and contacts with the inner wall of the rotating gear ring 401, thereby clamping and fixing the rotating gear ring 401, achieving the limiting effect, and during the rotation of the first rotating plate 300 and other structures, the rotating pressure plate 500 and the extrusion block 504 can rotate synchronously with the clamping block 402, the rotating gear ring 401 and the first rotating plate 300, thereby ensuring the limiting effect on the rotating gear ring 401.

[0090] In the fourth embodiment, the structure is basically the same as that of the first embodiment, and the difference lies in that the double-station turning mechanism comprises a sliding seat 105 slidably connected to the top of the base 100, as shown in Figure 3 , one side of the sliding seat 105 is connected with the first hydraulic rod 106, and the top is fixed with a vertical moving frame 104, two inclined straight grooves are symmetrically arranged on the moving frame 104, and the positions of the straight grooves correspond to the positions of the two positioning mechanisms on the top of the same rotating assembly, an inclined second hydraulic rod 107 is arranged in the straight groove of the sliding seat 105, the top end of the second hydraulic rod 107 extends out of the moving frame 104 and is fixed with a tool holder 108, and the tool holder 108 is provided with a turning tool 109 on the side close to the fixed seat 102.

[0092] The two turning tools 109 on the moving frame 104 are respectively used for turning the outer wall and the inner wall of the drill pipe joint, and the cutter holder 108 and the turning tool 109 are adjusted to move along the radial direction of the first rotating plate 300 by the second hydraulic rod 107, so as to adjust the position of the turning tool 109 relative to the drill pipe structure, and the moving frame 104 drives the turning tool 109 to move by the first hydraulic rod 106, so as to move along the length direction of the drill pipe joint during the moving process, and the turning process of the rotating drill pipe joint is carried out.

[0093] In the fifth embodiment, the structure is basically the same as that of the first embodiment, and the difference is that, as shown in Figure 1 、 Figure 2 The conveying assembly comprises two fixed frames 201 which are symmetrically arranged and located outside the second rotating plate 301, the bottom ends of the fixed frames 201 are fixed with the top portions of the corresponding moving seats 101 and fixed seats 102, the top outer sides of the fixed frames 201 are rotationally connected with two parallel conveying wheels 202, the two conveying wheels 202 are jointly provided with a conveying belt 200, one end of one of the conveying wheels 202 is fixed with a first bevel gear 203, the bottom portion of the first bevel gear 203 is engaged with a second bevel gear 204, the second bevel gear 204 is connected with a motor, and the motor is connected with the fixed frame 201.

[0094] When the oil drill pipe is fed, the two side sections of the drill pipe are located on the conveying belt 200 on the same side of the fixed seat 102 and the moving seat 101, and the conveying wheel 202 drives the conveying belt 200 and the oil drill pipe thereon to move towards the positioning mechanism by the driving of the motor and the transmission of the first bevel gear 203 and the second bevel gear 204, so as to take and position the oil drill pipe by the rotating positioning mechanism; after the oil drill pipe completes the turning process of the two stations, the oil drill pipe moves above the conveying belt 200 on the other side, the positioning mechanism cancels the positioning of the oil drill pipe, the oil drill pipe falls onto the conveying belt 200, and is conveyed outwardly by the conveying belt 200, and is staggered with the structure position of the positioning mechanism, so as to avoid affecting the rotation of the positioning mechanism.

[0095] As shown in Figure 2 , a plurality of limiting convex strips are uniformly arranged on the outer side of the conveying belt 200, and each group comprises two parallel limiting convex strips, the limiting convex strips are perpendicular to the side edges of the conveying belt 200, when the drill pipe is located on the conveying belt 200, the bottom portion is located between the corresponding two limiting convex strips, so as to limit the position of the drill pipe, and avoid the rolling of the drill pipe relative to the conveying belt 200 during the conveying process.
