Description

Technical Field

[0002] A pressure vessel refers to a closed device that contains gas or liquid and bears a certain pressure. During the production of a pressure vessel, adjacent container parts need to be seamlessly welded using welding equipment. During this welding process, an auxiliary docking device is required to support the two container parts and assist in docking the two container parts before welding.

[0003] The pressure vessel welding and docking devices designed in the related art mostly include a workbench and arc-shaped support plates arranged on both sides of the workbench. The arc-shaped support plates can be close to each other, and fixed brackets that can be telescopically adjusted are fixed on both sides of the arc-shaped support plates. During docking, the pressure vessel is placed on the arc-shaped support plate. After the arc-shaped support plate supports the pressure vessel, the fixed brackets on both sides of the arc-shaped support plate are pressed against the pressure vessel to fix the pressure vessel. Then, the arc-shaped support plates at both ends are brought close to each other to dock the pressure vessel interfaces, which is convenient for subsequent welding operations.

[0004] In the existing technology, especially for submerged arc welding, during welding, only the flux in the weld is utilized, but the flux on both sides of the weld will fall off with the rotation welding of the welded parts, resulting in waste of flux; some equipment is provided with a material box to recycle the flux, but the welding slag generated during welding will also fall into the material box, and the operator will need to separate the materials later, which not only consumes manpower, but is also not conducive to improving the recovery purity of the flux.

[0016] The present invention has the following beneficial effects:

[0017] 1. This pressure vessel welding docking device is provided with a striking assembly, specifically including an electromagnet and a striking rod. By controlling the start and stop of the electromagnet and cooperating with the elastic connection of the second spring, the striking rod is driven to strike the cylinder to be welded, thereby promptly removing welding slag and excess flux on both sides of the weld, and using a material receiving box provided on the base to collect them, thereby avoiding waste of flux;

[0018] 2. This pressure vessel welding docking device is provided with a material distribution component, which includes a material receiving box and a filter plate in the material receiving box in sequence. The material receiving box is used to collect the flux, and the filter plate is used to separate the welding slag and the flux. A scraper is slidably provided on the material receiving box, and the scraper and the filter plate are in contact with each other. The scraper moves the welding slag and the flux to accelerate the falling speed of the flux. The scraper moves back and forth to move the welding slag into the distribution box for separate collection of the welding slag, thereby separating and collecting the welding slag and the flux.

[0019] 3. A pressure vessel welding docking device is provided with a vibration assembly, the vibration assembly includes a first rotating shaft between the supporting ear plate and the supporting ear plate, a knocking frame is connected to the first rotating shaft, and the reciprocating movement of the knocking rod drives the movable plate elastically connected to one side of the third vertical plate to move up and down, thereby pushing one side of the knocking frame, and the knocking frame is rotated on the first rotating shaft by the first torsion spring, so that the other side of the knocking frame can reciprocate to knock the docking material box.

Therefore, a convex ridge is provided on the side of the movable plate close to the dispersion plate. As the movable plate moves up / down, the convex ridge is used to move one side of the dispersion plate, and the torsion of the second torsion spring is used to drive the dispersion plate on the other side to disperse the falling welding slag and flux while preventing the falling flux and welding slag from accumulating together. This not only promotes the separation of welding slag and flux, but also improves the utilization rate of the filter plate, thereby accelerating the falling of the flux and improving the collection efficiency of the flux.

[0021] 5. This kind of docking device for pressure vessel welding, by setting a partition in the receiving box and a dividing plate rotating between two adjacent groups of partitions, can still use the up / down movement of the movable plate to push the guide rod to drive the lever on one side of it to move the rocker arm. Since the rocker arm is vertically connected to the top of the third rotating shaft and the dividing plate is connected to one side of the third rotating shaft, the lateral movement of the guide rod can drive the dividing plate to swing a certain angle in the receiving box, thereby mixing the welding slag and flux.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] For example 1, please refer to Figures 1 to 10 The present invention discloses a docking device for pressure vessel welding, comprising a base 1, a first vertical plate 2 being slidably connected to one side of the base 1 via an electric slide 28, a second vertical plate 3 being provided on the other side of the base 1, three-jaw chucks 4 being connected to opposite sides of the first vertical plate 2 and the second vertical plate 3, a first motor 5 being provided on one side of the second vertical plate 3, an output shaft end of the first motor 5 being transmission-connected to the three-jaw chuck 4, a lifting plate 6 being provided on the base 1, and two sets of limit seats 7 being symmetrically provided on the lifting plate 6.

[0035] In this embodiment, a first vertical plate 2 and a second vertical plate 3 are respectively provided on the base 1, and a three-jaw chuck 4 is connected to one side of the first vertical plate 2 and the second vertical plate 3. Two sets of three-jaw chucks 4 can be used to quickly clamp and position the pressure vessel to be welded, wherein the first vertical plate 2 is slidably connected to the base 1 through an electric slide 28, and the distance between the first vertical plate 2 and the second vertical plate 3 can be adjusted according to the size of the pressure vessel to be welded.

[0036] Specifically, before welding, the cylinder to be welded is placed on two sets of limit seats 7, the external cylinder is started, and the lifting plate 6 is pushed up so that the center line of the cylinder to be welded and the two sets of three-jaw chucks 4 are on the same horizontal line, and the electric slide 28 is started to drive the first vertical plate 2 to move, and the cylinder to be welded is pushed to be stably clamped between the first vertical plate 2 and the second vertical plate 3. A welding machine is provided on one side of the base 1 so that the welding head 53 is aligned with the joint of the cylinder to be welded, and then the external cylinder is controlled to drive the limit seat 7 to descend and reset, and the first motor 5 is started to drive the cylinder to be welded to rotate, and the external welding machine is started at the same time for welding, and flux is filled into the weld while welding.

[0037] The lifting plate 6 further comprises a material receiving box 8 for collecting welding slag and flux. The material receiving box 8 is elastically connected to the base 1 via a first spring 14 . A through slot 29 matching the material receiving box 8 is provided in the lifting plate 6 .

[0038] In this embodiment, a material receiving box 8 is provided on the base 1 below the docking position of the cylinder to be welded. To ensure the normal lifting and lowering of the lifting plate 6, a through groove 29 is opened in the lifting plate 6 to prevent interference between the material receiving box 8 and the lifting plate 6.

[0039] Example 2: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 10The receiving box 8 is arranged just below the welding joint, and a knocking assembly is provided on one side of the receiving box 8. The knocking assembly includes a third vertical plate 16, and the third vertical plate 16 is fixedly installed on one side of the base 1. One side of the third vertical plate 16 is connected to a bracket 17, and an electromagnet 18 is installed in the bracket 17. One side of the third vertical plate 16 is slidably connected to a knocking rod 19, and the electromagnet 18 and the knocking rod 19 are matched. One side of the third vertical plate 16 is connected to a connecting plate 25 through a second spring 20, and one side of the connecting plate 25 is fixedly connected to the knocking rod 19.

[0040] In this embodiment, a third vertical plate 16 is installed on one side of the cylinder to be welded and on the base 1, and a bracket 17 is connected to one side of the third vertical plate 16. An electromagnet 18 is installed on the bracket 17, and a knocking rod 19 is slidingly set in the third vertical plate 16. The knocking rod 19 and the electromagnet 18 are reciprocated by starting and stopping the electromagnet 18. At the same time, the other side of the third vertical plate 16 is connected to the connecting plate 25 through the second spring 20, and the connecting plate 25 is connected to the knocking rod 19. Therefore, when the electromagnet 18 is turned off, the second spring 20 resets and drives the knocking rod 19 to impact the cylinder to be welded, thereby knocking the cylinder to be welded, which can prevent the welding slag from solidifying on the surface of the cylinder to be welded, and can also quickly make the excess flux and welding slag fall into the material box 8 for recycling the flux, saving welding resources.

[0041] Example 3: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 10 A material separation component is provided in the material receiving box 8, and the material separation component is used to separate and collect welding slag and flux. The material separation component includes a filter plate 9 installed in the material receiving box 8, and a scraper 12 is slidably connected to the material receiving box 8. The scraper 12 and the upper surface of the material receiving box 8 are fitted together, and one end of the scraper 12 is connected to a transverse block 13. A screw rod 10 is rotatably installed on one side of the outer wall of the material receiving box 8, and an internal threaded sleeve is provided between the transverse block 13 and the screw rod 10. One end of the screw rod 10 is transmission-connected to a second motor 11, and a pulley 54 is provided at the end of the scraper 12 away from the transverse block 13.

[0042] In this embodiment, a filter plate 9 is provided in the material receiving box 8, and the fallen welding slag and flux fall onto the filter plate 9. Since the particles of welding slag are much larger than the flux, the welding slag and flux that fall onto the filter plate 9 will be separated by the filter plate 9. The flux falls into the material receiving box 8 through the filter plate 9, and the welding slag accumulates above the filter plate 9. As a result, the welding slag and flux can be automatically separated and collected after falling, without manual operation, thereby improving the collection efficiency of the flux.

[0043] A scraper 12 capable of reciprocating movement is provided on the filter plate 9. Since one end of the scraper 12 is connected to a transverse block 13, an internal threaded sleeve is connected between the transverse block 13 and the screw rod 10. The internal threaded sleeve is rotatably connected to the transverse block 13 through a bearing. The second motor 11 is started to drive the screw rod 10 to rotate, thereby driving the transverse block 13 to move along the screw rod 10 through the internal threaded sleeve, thereby driving the scraper 12 to reciprocate on the surface of the filter plate 9, performing back and forth material processing on the welding slag and flux, further separating the welding slag and flux more effectively, and accelerating the speed at which the flux falls through the filter plate 9 into the material receiving box 8.

[0044] Example 4: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 10 A vibration assembly is provided at the bottom of the receiving box 8, and the vibration assembly includes two groups of supporting ear plates 30 and a first rotating shaft 34 rotatably connected between the two groups of supporting ear plates 30. A knocking frame 32 is connected to the surface of the first rotating shaft 34, and a first torsion spring 31 is connected between the two sides of the knocking frame 32 and the supporting ear plates 30. The first torsion spring 31 is sleeved on both ends of the first rotating shaft 34, and a rubber pad 33 is provided on the knocking frame 32.

[0045] In this embodiment, a supporting ear plate 30 is provided at the bottom of the material receiving box 8, a first rotating shaft 34 is provided between the two groups of supporting ear plates 30, and a knocking frame 32 is connected to the first rotating shaft 34. At the same time, a first torsion spring 31 is used to connect the supporting ear plate 30 and the knocking frame 32, and the first torsion spring 31 is sleeved on both ends of the first rotating shaft 34. The knocking frame 32 is moved back and forth on one side of the first rotating shaft 34, so that the other side of the knocking frame 32 knocks on the bottom of the material box 8. Since the material receiving box 8 is elastically connected to the base 1 through the first spring 14, the knocking of the knocking frame 32 on the material box 8 will cause the material receiving box 8 to shake, further improving the separation speed and separation effect of the welding slag and flux.

[0046] Two groups of support blocks 24 are symmetrically connected to one side of the third vertical plate 16. The top of the support block 24 is connected to the support plate 22 through the third spring 23. One side of the support plate 22 is slidingly connected to the third vertical plate 16. A movable plate 21 is connected inside the support plate 22. The bottom surface of the knocking rod 19 has equidistant arrays of protrusions 26. The top of the movable plate 21 and the protrusions 26 are elastically fitted together.

[0047] In this embodiment, a movable plate 21 is provided on one side of the third vertical plate 16, and the third spring 23 and the support block 24 are used in sequence to make the movable plate 21 elastically and slidably connected to one side of the third vertical plate 16, and by providing a protrusion 26 at the bottom of the knocking rod 19, the knocking rod 19 is used to slide back and forth in the horizontal direction, driving the protrusion 26 to move on the top of the movable plate 21, thereby pushing the movable plate 21 to move back and forth in the vertical direction, and the downward movement of the movable plate 21 is used to press down one side of the knocking frame 32, so that the knocking frame 32 on the other side knocks the docking material box 8, and when the movable plate 21 moves upward, the knocking frame 32 is driven to reset by the torsion of the first torsion spring 31. Therefore, the knocking rod 19 is used to drive the movable plate 21 to move up and down, which can drive the knocking frame 32 to knock the docking material box 8.

[0048] Example 5: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 10 A material spreading assembly is provided on one side of the material receiving box 8, and the material spreading assembly includes a mounting bracket 35 fixedly connected to one side of the outer wall of the material receiving box 8, and a second rotating shaft 36 is rotatably connected in the mounting bracket 35, and a dispersion plate 37 is provided on the second rotating shaft 36, and a driving plate 39 is connected to one side of the dispersion plate 37. There are convex ridges 27 in an equidistant array on one side of the movable plate 21, and the driving plate 39 extends between the two groups of convex ridges 27. Second torsion springs 38 are sleeved on both ends of the second rotating shaft 36, and the second torsion springs 38 are connected between the mounting bracket 35 and the dispersion plate 37.

[0049] Taking into account that the flux is only stacked at the docking position, most of it accumulates in the center position of the receiving box 8 and is biased to one side of the receiving box 8 when it falls, resulting in a reduced collection utilization rate of the receiving box 8. Therefore, in this embodiment, a spreading assembly is provided at the falling position of the flux. Specifically, a mounting frame 35 is connected to one side of the outside of the receiving box 8, and a dispersion plate 37 is elastically and rotatably connected to the top of the mounting frame 35 through a second torsion spring 38. There are ribs 27 in an equidistant array on one side of the movable plate 21. As the movable plate 21 moves up / down, the ribs 27 are used to move one side of the dispersion plate 37 around the second rotating shaft 36, thereby dispersing the fallen flux and welding slag, so that they are distributed as evenly as possible at various positions in the receiving box 8, thereby improving the utilization rate of the receiving box 8 and further promoting the separation of welding slag and flux, and preventing welding slag and flux from piling up after falling.

[0050] Example 6: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 10 There are partitions 47 in an equidistant array in the receiving box 8, and a sliding groove matching the partitions 47 is opened in the scraper 12. A dividing plate 43 is provided on one side of the scraper 12 and between two adjacent groups of partitions 47. The dividing plate 43 is rotatably connected to one side of the scraper 12 through a third rotating shaft 44.

[0051] In this embodiment, a partition 47 is provided within the material receiving box 8. Since the scraper 12 slides on the filter plate 9 to remove the material, a chute is provided within the scraper 12 that matches the partition 47 to ensure that the two do not interfere with each other during the material removal process. Separator plates 43 are also provided between adjacent separators 47. The swinging of the separator plates 43 causes the mixed particles of welding slag and flux to collide with the partitions 47, further separating the two.

[0052] A guide rod 41 is provided at the top of the scraper 12, a fourth spring 46 is connected between the scraper 12 and the guide rod 41, a shift rod 42 is provided on one side of the guide rod 41, a rocker rod 45 vertically connected to the third rotating shaft 44 is connected to the top of the third rotating shaft 44, the rocker rod 45 is provided between the two groups of shift rods 42, a drive frame 40 is connected to one side of the knocking rod 19, a drive block 52 is provided at one end of the guide rod 41 close to the drive frame 40, and the drive frame 40 and the drive block 52 are matched.

[0053] Specifically, a guide rod 41 is provided at the top of the scraper 12, and one end of the guide rod 41 is elastically and slidably connected to the scraper 12 through a fourth spring 46, and a toggle rod 42 is connected to one side of the guide rod 41, and each two toggle rods 42 form a group, and a rocker rod 45 is connected to the top of the third rotating shaft 44 supporting the toggle rod 42, and the rocker rod 45 is arranged between the two groups of toggle rods 42, and the bottom of the movable plate 21 is connected to the driving frame 40, and a driving block 52 is provided at one end of the guide rod 41. One side of the driving frame 40 and the driving block 52 are provided with mutually matching inclined cross-sections. When the driving frame 40 floats up and down with the movable plate 21, the inclined surface below the driving frame 40 generates thrust on the inclined surface on one side of the driving block 52, so that the guide rod 41 slides above the scraper 12, and the two groups of toggle rods 42 set on one side of the guide rod 41 will toggle the rocker rod 45 to drive the third rotating shaft 44 to rotate, thereby driving the dividing plate 43 to swing back and forth.

[0054] Example 7: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 10 , distribution boxes 15 are provided on both sides of the receiving box 8, and a feed port 49 connected to the receiving box 8 is opened on one side of the distribution box 15. A sealing plate 48 is pinned inside the feed port 49, and a third torsion spring 50 is provided between the two ends of the sealing plate 48 and the distribution box 15. The bottom of the distribution box 15 passes through and extends to the bottom of the base 1, and a discharge port 51 is opened at the bottom of the distribution box 15.

[0055] In this embodiment, a distribution box 15 is provided on both sides of the receiving box 8. The scraper 12 pushes the welding slag remaining on the filter plate 9 after filtration into the distribution box 15 through reciprocating movement, and then discharges it through the discharge port 51, thereby separating the welding slag and flux.

[0056] In order to prevent the flux from falling directly into the distribution box 15 through the feed port 49 after it falls, a sealing plate 48 is provided in the feed port 49. The sealing plate 48 is elastically rotatably connected to the feed port 49 through two sets of third torsion springs 50. A push rod 55 is provided on one side of the sealing plate 48. When the scraper 12 moves to a certain position, the sealing plate 48 can be opened by pushing the push rod 55, thereby pushing the welding slag particles into the distribution box 15 to complete the distribution of welding slag and flux.
