Description

Technical Field

[0001] The present invention relates to the technical field of drilling, and particularly to a drilling process for large orifice plates. Background Art

[0002] A throttle orifice plate is a device used for pipeline fluid control. When the pressure difference before and after the pipeline is large, the method of increasing the throttle orifice plate is often adopted. Its principle is that when the fluid flows in the pipeline, due to the local resistance of the orifice plate, the pressure of the fluid decreases and energy is lost. This phenomenon is called the throttling phenomenon in thermodynamics. This method is simpler than using a control valve, but it must be properly selected. Otherwise, cavitation is likely to occur in the liquid, affecting the safe operation of the pipeline.

[0003] However, in the actual use process, the inventor found that when processing large orifice plates, the orifice plates are usually placed horizontally for drilling, and the generated waste chips are difficult to clean. The large orifice plates are heavy and have no grasping points, which is not convenient for hoisting and transferring, affecting the drilling effect of the orifice plates. Summary of the Invention

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0035] Embodiment 1 As Figures 1-3 and Figure 7 shown, a large orifice drilling process includes the following steps: Step 1, welding ear process: symmetrically weld two groups of ear plates 7 on the circumferential side surface of a horizontally placed circular plate 6. The ear plates 7 are provided with lifting holes 72 and positioning holes 71 by themselves; Step 2, lifting process: a lifting mechanism 2 lifts the circular plate 6 upward through the ear plates 7, adjusts the circular plate 6 to a vertical state, and then transfers the circular plate 6 to the position to be drilled; Step 3, drilling process: a positioning component 42 supports the circular plate 6 in a vertical state and limits the circular plate 6 through the ear plates 7. A rotating component 43 drives the circular plate 6 to rotate intermittently by itself to adjust the drilling position, so as to sequentially drill holes at specified positions on the circular plate 6. During the rotation of the circular plate 6, a cleaning component 44 cleans the waste chips in the hole diameter of the circular plate 6; Step 4, ear cutting process: after the circular plate finishes the drilling work, transfer the circular plate to the position to be cut, then cut off the ear plates from the circular plate, and polish the circumferential side surface of the circular plate. The cut-off ear plates are reused.

[0036] It is worth mentioning that in Step 1, the circular plate 6 and the two groups of ear plates 7 are placed on the same horizontal plane. The arc surfaces of the two groups of ear plates 7 are symmetrically attached to the circumferential side surface of the circular plate 6 respectively. The gap between the arc surface of the ear plate 7 and the circumferential side surface of the circular plate 6 is filled with solder, and the positions of the circular plate 6 and the two groups of ear plates 7 are limited.

[0037] In this embodiment, by pre-welding two ear plates on the circumferential side surface of the circular plate, on the one hand, it is convenient to lift and transfer the circular plate, without damaging the surface of the circular plate, and can adjust the circular plate to a vertical state, so that the circular plate is drilled in a vertical state, and the generated waste chips are easily discharged, and holes can be automatically drilled on the circular plate sequentially, improving the drilling effect of the circular plate; on the other hand, during the process of the circular plate rotating by itself for drilling, the residual waste chips in the hole diameter of the circular plate 6 can be automatically cleaned, ensuring the cleanliness of the circular plate.

[0038] Embodiment 2 As Figures 2-16 shown, where the same or corresponding components as those in Embodiment 1 are denoted by the corresponding reference numerals in Embodiment 1. For the sake of simplicity, only the differences from Embodiment 1 will be described hereinafter. The differences between this Embodiment 2 and Embodiment 1 are as follows: As Figures 2-4 and Figure 7 shown, it is applied to a drilling device for a large orifice drilling process. The drilling device includes a hoisting mechanism 2, a welding ear mechanism 3, a drilling mechanism 4, and a cutting ear mechanism 5 provided on a frame 1; The drilling mechanism 4 includes a drilling assembly 41 provided on the frame 1, a positioning assembly 42 provided on the frame 1 and used to support a circular plate 6 in a vertical state, a rotating assembly 43 provided on the positioning assembly 42 and used to drive the circular plate to rotate intermittently by itself, and a cleaning assembly 44 provided on the frame 1 and used to clean the chips in the holes of the circular plate; The drilling assembly 41 is lifted and lowered in the vertical direction to drill holes in the surface of the circular plate in sequence. The positioning assembly 42 restricts the circular plate to be in a vertical state. The rotating assembly 43 drives the circular plate to rotate intermittently by itself to adjust the drilling position. During the self-rotation of the circular plate, the cleaning assembly 44 cleans the chips in the holes of the circular plate.

[0039] In this embodiment, the functions of the two ear plates welded on the circumferential side surface of the circular plate are as follows: One is to facilitate the hoisting and transfer of the circular plate, adjust the circular plate to be in a vertical state for drilling, and during the process of the circular plate rotating by itself for drilling, the convex blocks 73 on the ear plates intermittently drive the cleaning assembly 44 to clean the residual chips in the holes of the circular plate; The other is that after the circular plate completes the drilling work, the ear plates can be separated from the circular plate, and the cut ear plates can be reused.

[0040] Furthermore, as Figure 2 and Figures 12-14 shown, the hoisting mechanism 2 includes: A third sliding table 21, the third sliding table 21 is provided on the frame 1, and a third mounting bracket 22 is provided on the third sliding table 21; A hanging bracket 23, a second hydraulic component 24 is provided on the third mounting bracket 22, the hanging bracket 23 is provided on the output shaft of the second hydraulic component 24, a rotating rod 25 is rotatably provided on the hanging bracket 23, two groups of fixing blocks 26 are symmetrically provided on the rotating rod 25, and a second motor 27 for driving the rotating rod 25 is provided on the hanging bracket 23; The L-shaped suspension rod 28, two groups of the L-shaped suspension rods 28 are symmetrically and hingedly arranged at the bottom of the fixed block 26. A third hydraulic member 29 is arranged at the bottom of the fixed block 26. A suspension block 291 is arranged on the output shaft of the third hydraulic member 29. Two groups of transmission rods 292 are symmetrically and hingedly arranged on the suspension block 291. One ends of the two groups of transmission rods 292 are respectively hingedly arranged with the L-shaped suspension rods 28 and are used for adjusting the opening angle of the two groups of L-shaped suspension rods 28.

[0041] It is worth mentioning that vertical holes corresponding to the hanging holes 72 of the ear plates are opened on both the first positioning groove 33 and the second positioning groove 53. The vertical holes are for the two groups of L-shaped suspension rods 28 to pass through, so that the two groups of L-shaped suspension rods 28 are stuck in the hanging holes 72 of the ear plates.

[0042] It should be noted that the third mounting bracket 22 on the third sliding table 21 is driven by a linear motor of the prior art.

[0043] In this embodiment, by the cooperation of the lifting mechanism 2 and the ear plate 7, the circular plate can be automatically lifted, adjusted to a vertical state, and transferred to a designated position for release. The clamping is firm, the lifting is stable, and the circular plate is prevented from being knocked and dropped.

[0044] Specifically, the third sliding table 21 drives the L-shaped suspension rod 28 on the third mounting bracket 22 to horizontally move to a designated position. The second hydraulic member 24 drives the L-shaped suspension rod 28 on the hanging bracket 23 to descend. At the same time, the third hydraulic member 29 drives the suspension block 291 to rise, so that the suspension block 291 drives the two groups of L-shaped suspension rods 28 to approach each other through the two transmission rods 292, reducing the opening angle of the two groups of L-shaped suspension rods 28. The L-shaped suspension rod 28 descends through the hanging holes 72 of the two groups of ear plates. Then, the third hydraulic member 29 drives the suspension block 291 to descend, so that the suspension block 291 drives the two groups of L-shaped suspension rods 28 to move away from each other through the two transmission rods 292, increasing the opening angle of the two groups of L-shaped suspension rods 28, so that the two groups of L-shaped suspension rods 28 are stuck in the hanging holes 72 of the ear plates. Then, the second hydraulic member 24 drives the L-shaped suspension rod 28 on the hanging bracket 23 to rise, so that the L-shaped suspension rod 28 lifts the circular plate through the two groups of ear plates. At the same time, the second motor 27 drives the rotating rod 25 to drive the L-shaped suspension rod 28 to rotate 90 degrees, so that the circular plate is in a vertical state. Then, the third sliding table 21 drives the L-shaped suspension rod 28 on the third mounting bracket 22 to transfer the circular plate to a designated position. The second hydraulic member 24 drives the L-shaped suspension rod 28 on the hanging bracket 23 to descend, so that the vertically placed circular plate descends onto the arc-shaped supporting portion 428 of the positioning assembly 42. The opening angle of the two groups of L-shaped suspension rods 28 is reduced again. The third sliding table 21 drives the L-shaped suspension rod 28 on the third mounting bracket 22 to horizontally move out of the hanging holes 72 of the ear plates, completing the lifting and transfer work of the circular plate.

[0045] Further, as Figure 2 and Figure 15 shown, the welding ear mechanism 3 includes: The first bearing plate 31 is arranged on the frame 1. A first placement groove 32 for laying the circular plate flat is formed in the first bearing plate 31, and a first positioning groove 33 communicating with the first placement groove 32 and for laying the ear plate flat is formed in the first bearing plate 31; The first lead screw 34. Two groups of the first lead screws 34 are rotatably arranged on the first bearing plate 31 and symmetrically located on both sides of the first placement groove 32. A first threaded block 35 is arranged on the first lead screw 34. A welding torch 36 is arranged on the first threaded block 35. A fourth hydraulic component 37 for driving the welding torch 36 to move horizontally is arranged on the first threaded block 35. A third motor 38 for driving the first lead screw 34 is arranged on the first bearing plate 31; Welding rod holes 39. Two groups of the welding rod holes 39 are symmetrically formed in the first bearing plate 31. The welding torch 36 welds the ear plate on the circumferential side surface of the circular plate along the welding rod holes 39.

[0046] It should be noted that the structure and function of the welding torch 36 are both prior arts and will not be elaborated herein.

[0047] In this embodiment, by arranging the ear welding mechanism 3, it is convenient to symmetrically weld two groups of ear plates on the circumferential side surface of the circular plate. The arc surface of the ear plate fits the circumferential side surface of the circular plate, and the ear plate can be welded tightly on the circular plate along the arc-shaped welding path, making the welding more firm.

[0048] Specifically, the circular plate is laid flat in the first placement groove 32 on the first bearing plate 31. The hoisting mechanism 2 lays two groups of ear plates cut by the ear cutting mechanism 5 flat in the first positioning groove 33. Then, the third motor 38 drives the first threaded block 35 to drive the welding torch 36 to move horizontally left and right through the first lead screw 34. At the same time, the fourth hydraulic component 37 drives the welding torch 36 to move horizontally back and forth, so that the welding torch 36 takes the circumferential side of the circular plate as the welding path and welds the arc surface of the ear plate on the circumferential side surface of the circular plate.

[0049] Further, as Figures 3-9 shown, the positioning assembly 42 includes: A bracket 421. The bracket 421 is arranged on the frame 1. A rotating shaft 422 is rotatably arranged on the bracket 421. A cross beam 423 is fixedly arranged on the rotating shaft 422; An annular gear 424. The inner wall of the annular gear 424 is arranged at both ends of the cross beam 423; A bearing frame 425. Two groups of the bearing frames 425 are symmetrically arranged on the annular gear 424 through connecting rods 426 respectively and are used for supporting the ear plates 7 on the circular plate 6. A jack 427 matching the positioning hole 71 of the ear plate 7 is formed in the bearing frame 425; The arc-shaped support part 428 is arranged between two groups of the bearing frames 425 and is used for supporting the bottom of the circular plate in a vertical state; The inserting rods 429 penetrate through and are slidably arranged on the annular gear 424 respectively, and are used for sequentially inserting into the jack holes 427 of the bearing frames 425 and the positioning holes 71 of the ear plates 7. A convex plate 4291 is arranged at one end of the inserting rod 429. A first elastic member is arranged between the convex plate 4291 and the annular gear 424. The inserting rod 429 is inserted into the jack hole 427 of the bearing frame 425 under the elastic force of the first elastic member; The calipers 4292. Two groups of first hydraulic members 4293 are symmetrically arranged on the support 421. The two groups of calipers 4292 are respectively arranged on the output shafts of the first hydraulic members 4293 and are used for driving the inserting rod 429 to move horizontally through the convex plate 4291; The rotating assembly 43 includes two groups of first motors 431 symmetrically arranged on the support 421 and a driving gear 432 arranged on the output shaft of the first motor 431 and used for driving the annular gear 424.

[0050] In this embodiment, through the cooperation of the positioning assembly 42 and the rotating assembly 43, on the one hand, it can support and position the circular plate in a vertical state, prevent the circular plate from toppling during the drilling process, with good positioning effect, avoid the inclination of the hole diameter on the circular plate, and improve the drilling forming effect of the circular plate; on the other hand, during the process of the circular plate rotating and drilling by itself, it can prevent the circular plate from deflecting and sliding, with accurate drilling position, and avoid the overlap of the hole diameters on the circular plate.

[0051] Specifically, the first hydraulic member 4293 drives the convex plate 4291 through the caliper 4292 to drive the inserting rod 429 to move horizontally away from the jack hole 427 of the bearing frame 425. The hoisting mechanism 2 places the circular plate in a vertical state on the arc-shaped support part 428. At the same time, the two groups of ear plates are respectively located in the bearing frames 425. The first hydraulic member 4293 drives the caliper 4292 to move horizontally and reset. The inserting rod 429 is inserted into the jack hole 427 of the bearing frame 425 and the positioning hole 71 of the ear plate 7 under the elastic force of the first elastic member, so as to position the circular plate on the arc-shaped support part 428. Then, the first motor 431 drives the annular gear 424 to intermittently rotate a specified angle through the driving gear 432. The annular gear 424 drives the circular plate to intermittently rotate by itself through the connecting rod 426 and the inserting rod 429, so that the circular plate sequentially completes the drilling work.

[0052] Further, as Figures 2-3 shown, the drilling assembly 41 includes: The first sliding table 411 is arranged on the frame 1, and a first mounting frame 412 is arranged on the first sliding table 411; The second sliding table 413 is provided on the first mounting bracket 412. A second mounting bracket 414 is provided on the second sliding table 413, and a drilling unit 415 is provided on the second mounting bracket 414. The drilling unit 415 includes a driving motor and a drill bit in the prior art.

[0053] It is worth mentioning that the first mounting bracket 412 on the first sliding table 411 and the second mounting bracket 414 on the second sliding table 413 are respectively driven by linear motors in the prior art.

[0054] Specifically, during the intermittent self-rotation of the circular plate, when the circular plate stays, the first sliding table 411 drives the drilling unit 415 to move horizontally, and the second sliding table 413 drives the drilling unit 415 to lift, so that the drilling unit 415 drills holes in sequence at the specified positions on the circular plate.

[0055] Further, as Figures 3-11 shown, the cleaning assembly 44 includes: A power disk 441, which is penetrated and slidably arranged on the rotating shaft 422 at the middle position. A second elastic member 442 is arranged between the power disk 441 and the end of the rotating shaft 422; Cleaning rods 443, several groups of the cleaning rods 443 are penetrated and slidably arranged on the power disk 441 and are respectively corresponding to the drilling positions on the circular plate. A third elastic member is arranged between the end of the cleaning rod 443 and the power disk 441. Several groups of avoidance holes 444 for the cleaning rods 443 to pass through are formed on the cross beam 423; A sealed box 445, which is arranged on the support 421. Several groups of air bags 446 are evenly distributed on the sealed box 445 along the circumferential direction; Protrusions 73, two groups of the protrusions 73 are respectively arranged on the two ear plates 7 and are used for sequentially squeezing the air bags 446 during the self-rotation of the circular plate; A piston cylinder 447, which is arranged on the frame 1. The sealed box 445 is connected to the piston cylinder 447 through an air pipe 448. A piston piece 449 is slidably fitted inside the piston cylinder 447. A fourth elastic member 4491 is arranged between the piston piece 449 and the end of the piston cylinder 447; A limit block 4492, a linkage rod 4493 is arranged on the piston piece 449. The limit block 4492 is arranged at one end of the linkage rod 4493 that penetrates to the outside of the piston cylinder 447. A limit ring 4494 is arranged on the circumferential surface of the power disk 441. The limit block 4492 is slidably matched on the limit ring 4494.

[0056] It should be noted that several groups of cleaning rods 443 on the power disk 441 correspond one by one to the positions on the circular plate where holes are to be drilled. During each process of the power disk 441 driving the cleaning rods 443 to translate towards the circular plate, for the positions on the circular plate where holes have been drilled, the cleaning rods 443 are inserted into the hole diameters to clean the waste chips. For the positions on the circular plate where holes have not been drilled, one end of the cleaning rod 443 abuts against the position on the circular plate where holes have not been drilled, forcing the cleaning rod 443 to slide relatively on the power disk 441 and stretching the third elastic member. When the power disk 441 moves away from the circular plate and resets, the cleaning rod 443 resets under the drive of the third elastic member, waiting for the next use to ensure that the hole diameters on the circular plate where holes have been drilled can all be cleaned of waste chips.

[0057] In this embodiment, through the provided cleaning assembly 44, the residual waste chips in the hole diameters on the circular plate can be automatically cleaned, and the waste chips in the hole diameters on the circular plate are cleaned one by one, without omission.

[0058] Specifically, during the intermittent self-rotation of the circular plate, the power disk 441 rotates synchronously with the circular plate, so that the convex blocks 73 on the ear plate 7 sequentially squeeze the air bags 446 on the sealing box 445. The air bags 446 are deformed by the extrusion, and air is inflated into the piston cylinder 447 through the air pipe 448, causing the piston piece 449 in the piston cylinder 447 to move. The piston piece 449 drives the limiting block 4492 through the linkage rod 4493 to drive the power disk 441 to translate towards the circular plate. For the positions on the circular plate where holes have been drilled, the cleaning rods 443 are inserted into the hole diameters to clean the waste chips. For the positions on the circular plate where holes have not been drilled, one end of the cleaning rod 443 abuts against the position on the circular plate where holes have not been drilled, forcing the cleaning rod 443 to slide relatively on the power disk 441 and stretching the third elastic member. After the convex blocks 73 on the ear plate 7 disengage from the air bags 446, the air bags 446 return to their original state, and the piston piece 449 translates and resets under the drive of the fourth elastic member 4491, so that the piston piece 449 drives the limiting block 4492 through the linkage rod 4493 to drive the power disk 441 to move away from the circular plate and reset, while the cleaning rod 443 resets under the drive of the third elastic member, waiting for the next use.

[0059] Further, as Figure 2 and Figure 16 shown, the ear cutting mechanism 5 includes: A second bearing plate 51, the second bearing plate 51 is arranged on the frame 1, a second placement groove 52 for laying the circular plate flat is opened on the second bearing plate 51, and a second positioning groove 53 for laying the ear plate flat and communicating with the second placement groove 52 is opened on the second bearing plate 51; Second lead screw 54, two sets of the second lead screws 54 are rotatably arranged on the second bearing plate 51 and symmetrically located on both sides of the second placement groove 52. A second threaded block 55 is arranged on the second lead screw 54. A cutting tool 56 is arranged on the second threaded block 55. A fifth hydraulic component 57 for driving the cutting tool 56 to move horizontally is arranged on the second threaded block 55. A fourth motor 58 for driving the second lead screw 54 is arranged on the second bearing plate 51; Cutting strip holes 59, two sets of the cutting strip holes 59 are symmetrically formed on the second bearing plate 51. The cutting tool 56 cuts off the ear plates from the circumferential side surface of the circular plate along the cutting strip holes 59.

[0060] It should be noted that vertical holes corresponding to the hanging holes 72 of the ear plates are formed in both the first positioning groove 33 and the second positioning groove 53. These vertical holes are for two sets of the L-shaped suspension rods 28 to pass through, so that the two sets of the L-shaped suspension rods 28 are stuck in the hanging holes 72 of the ear plates.

[0061] In this embodiment, by providing the ear plate cutting mechanism 5, the ear plates can be cut off along the circumferential side surface of the circular plate, avoiding the loss of the ear plates and ensuring that the ear plates can be reused.

[0062] Specifically, the lifting mechanism 2 transfers the drilled circular plate to the position of the ear plate cutting mechanism 5, so that the circular plate is placed flat in the second placement groove 52 on the second bearing plate 51. At the same time, the two ear plates are respectively located in the second positioning grooves 53. Then, the fourth motor 58 drives the second threaded block 55 through the second lead screw 54 to drive the cutting tool 56 to move horizontally left and right, and at the same time, the fifth hydraulic component 57 drives the cutting tool 56 to move horizontally back and forth, so that the cutting tool 56 cuts off the ear plates along the circumferential side surface of the circular plate. The cut-off ear plates are reused. Finally, the circular plate is taken out for polishing.
