Description

Technical Field

[0001] This invention relates to the field of welding technology, and in particular to a temporary connection and fixing device for a spherical shell flap. Background Technology

[0002] When producing in spherical tanks or other similar spherical equipment, multiple spherical shell plates need to be spliced ​​together and then welded in sequence so that the multiple spherical shell plates are finally spliced ​​together into a whole spherical equipment. When welding the spherical shell plates, positioning blocks need to be welded to the spherical shell plates, and then the two spherical shell plates are temporarily connected and fixed by a gantry clamp before welding.

[0003] It should be noted that when the gantry clamp is secured to the two positioning blocks, the common practice is to insert wedges between the gantry clamp and the positioning blocks, and then adjust the gap and flatness between the two spherical shell plates by hammering the wedges. However, this method is obviously very laborious, and the use of wedges can easily damage the gantry clamp and the spherical shell plates, making them prone to deformation. This not only affects the production quality of the spherical equipment, but also easily damages the gantry clamp. In addition, the gantry clamp has no obstruction measures during welding, causing the sparks generated during welding to fly everywhere, which can easily burn the surface of the spherical shell plates, further affecting the production quality of the spherical equipment.

[0015] The beneficial effects of the temporary connection and fixing device for the spherical shell flap proposed in this invention are: In this invention, by setting up a multi-directional position adjustment mechanism, when temporarily connecting and fixing the spherical shell petals, turning the two adjusting brackets causes the adjusting brackets to drive the drive rod to rotate, which in turn drives the adjusting threaded rod to rotate. The drive rod rotates within the rotating cavity via an anti-disengagement ring, while the adjusting threaded rod rotates within the drive threaded hole. This drives the pressing and leveling seat to move horizontally within the limiting movement groove. The moving pressing and leveling seat presses the spherical shell petals, thus flattening the contact surfaces of the two spherical shell petals. Furthermore, the rotation of the drive rod drives the gear to move the adjusting rack, which in turn drives the lifting adjusting bracket to move. The lifting adjusting bracket then moves the wedge-shaped adjusting seat, thereby adjusting the gap between the spherical shell petals. This achieves the goal of adjusting the position of the spherical shell petals simply by rotating the adjusting brackets.

[0016] Furthermore, in this invention, by setting up a dust collection and shielding device, when using the gantry clamp, the gantry clamp is closed by two dust collection and shielding covers, so that the sparks generated during welding can be blocked by the dust collection and shielding covers, and then concentrated and extracted by two exhaust fans, and the dust is filtered by the dust collection filter plate, so as to avoid the problem of welding sparks splashing and damaging the spherical shell flap.

[0017] Furthermore, in this invention, by setting up a linkage cleaning device, when the dust collection hood is opened, the squeezing opening and closing pusher moves, thereby causing the rotating column to drive the linkage rod to rotate. When the linkage rod rotates, it drives the cleaning brush strip to move through the linkage sliding shaft, so that the cleaning brush strip cleans the dust collection filter plate. Similarly, when the dust collection hood is closed, the cleaning brush strip resets and cleans the dust collection filter plate again, so as to realize automatic cleaning of the dust collection filter plate during the opening and closing of the dust collection hood, ensuring the filtration effect of the dust collection filter plate.

[0028] It should be noted that, in this embodiment of the invention, when temporarily connecting and fixing the spherical shell flap 1, the gantry clamp 2 is placed on two positioning blocks 3, and the two adjusting rotating frames 408 are turned, so that the drive support rod 407 drives the adjusting threaded rod 401 to rotate in the drive threaded hole 410, which in turn causes the pressing and flattening seat 409 to move and press the spherical shell flap 1 to move, thereby making the pressing and flattening seat 409 press the contact surface of the two spherical shell flap 1 flat; in addition, the rotation of the drive support rod 407 drives the gear 414 to drive the adjusting rack 413 to move, so that the adjusting rack 413 drives the lifting adjusting frame 412 to move, and the movement of the lifting adjusting frame 412 drives the wedge-shaped adjusting seat 411 to move, so that the wedge-shaped adjusting seat 411 presses the positioning block 3, thereby adjusting the gap between the spherical shell flap 1, so that the position adjustment of the spherical shell flap 1 can be completed simply by rotating the adjusting rotating frame 408.

[0029] More specifically, in this embodiment of the invention, a dust collection and shielding device 6 is also included.

Two dust collection and shielding covers 602 are rotatably mounted on the connecting mounting plate 601. When closed, the two dust collection and shielding covers 602 shield the gantry clamp 2. It should be noted that in this embodiment of the invention, when using the gantry clamp 2, the two dust collection and shielding covers 602 close the gantry clamp 2, allowing the sparks generated during welding to be blocked by the dust collection and shielding covers 602. These sparks are then concentrated and extracted by two exhaust fans 8, and the dust is filtered by a dust collection filter plate 701, preventing welding sparks from splashing and damaging the spherical shell flap 1.

It should be noted that, in this embodiment of the invention, when the drive support rod 407 rotates, the driving gear 414 drives the adjusting rack 413 to move, which in turn drives the lifting adjustment frame 412 to move. The movement of the lifting adjustment frame 412 drives the wedge-shaped adjusting seat 411 to move, causing the wedge-shaped adjusting seat 411 to press against the positioning block 3, thereby achieving the purpose of adjusting the gap between the spherical shell flaps 1.

[0032] More specifically, in this embodiment of the invention, the positioning block 3 has two insertion holes 406, through which the adjusting threaded rod 401 passes, and the gantry clamp 2 has multiple connecting holes 415, through which the adjusting threaded rod 401 passes; both extrusion flat seats 409 have driving threaded holes 410, and the two adjusting threaded rods 401 are respectively threaded into the two driving threaded holes 410.

It should be noted that in this embodiment of the invention, when the opening and closing push frame 609 moves, it drives the synchronous extrusion shaft 712 to move, causing the synchronous extrusion shaft 712 to extrude the L-shaped extrusion frame 710 downwards, and causing the lifting spring 711 to be stretched, thereby achieving the purpose of moving and cleaning the two cleaning brushes 702.

[0041] In summary, the working principle of the temporary connection and fixing device for a spherical shell flap provided in this embodiment of the invention is as follows: When temporarily connecting and fixing the spherical shell flap 1, the gantry clamp 2 is placed on the two positioning blocks 3. At this time, the two adjusting threaded rods 401 are inserted from both sides of the gantry clamp 2, and the adjusting threaded rods 401 are rotated so that the adjusting threaded rods 401 pass through the extrusion flat seat 409 and the positioning block 3. Then, the gantry clamp 2 is moved so that the drive support rod 407 is inserted into the adjusting threaded rod 401. Then, the two adjusting rotating frames 408 are turned so that the adjusting rotating frames 408 drive the drive support rod 407 to rotate. The rotation of the drive support rod 407 drives the adjusting threaded rod 401 to rotate, and the drive support rod 407 rotates in the rotating cavity 403 through the anti-disengagement ring 404. At the same time, the adjusting threaded rod 401 rotates in the drive... Rotating within the threaded hole 410 drives the pressing and leveling seat 409 to move horizontally within the limiting movement groove 405. The moving pressing and leveling seat 409 presses the spherical shell flap 1 to move, thereby making the contact surface of the two spherical shell flaps 1 flat. In addition, the rotation of the drive rod 407 drives the gear 414 to drive the adjusting rack 413 to move, which in turn drives the lifting and adjusting frame 412 to move. The moving lifting and adjusting frame 412 drives the wedge-shaped adjusting seat 411 to move, which in turn presses the positioning block 3. This allows the gap between the spherical shell flaps 1 to be adjusted, thus achieving the purpose of adjusting the position of the spherical shell flaps 1 simply by rotating the adjusting frame 408. Furthermore, when using the gantry clamp 2, the exhaust mounting base 5 is bolted onto the gantry clamp 2. During installation of the gantry clamp 2, a dust collection hood 602 is rotated, causing it to rotate on both sides of the connecting mounting plate 601 via two opening and closing connecting shafts 606. This rotation forces two opening and closing torsion springs 608. Simultaneously, the rotation of the opening and closing connecting shafts 606 drives the synchronous gears 607 to rotate. The rotation of one synchronous gear 607 drives the rotation of the other synchronous gear 607, thus achieving the rotation of two... The synchronous rotation of the synchronous gear 607 allows the two dust collection hoods 602 to open synchronously. When they open, they push the rotating rod 610 to move, which in turn drives the two opening and closing pushers 609 to move. The opening and closing pushers 609 slide in the translational slide groove 611, which forces the return spring 612. The movement of the opening and closing pushers 609 drives the opening and closing drive shaft 613 to move, which in turn moves in the opening and closing drive groove 614, thereby driving the automatic closing plate 603 to close. It should be noted that the opening and closing drive shaft 613 slides within the opening and closing drive groove 614, and the automatic closing plate 603 closes to shut off the two exhaust fans 8, preventing impurities from falling into the exhaust fans 8 during the installation of the gantry clamp 2. Similarly, after the gantry clamp 2 is installed, the gantry clamp 2 is closed by the two dust-collecting shields 602, so that the sparks generated during welding can be blocked by the dust-collecting shields 602, and then concentrated and extracted by the two exhaust fans 8. The dust is filtered by the dust-collecting filter plate 701 to prevent the welding sparks from splashing and damaging the spherical shell flap 1. Furthermore, it should be noted that when the opening and closing push frame 609 moves, it drives the synchronous extrusion shaft 712 to move, causing the synchronous extrusion shaft 712 to extrude the L-shaped extrusion frame 710 downwards, and causing the lifting spring 711 to be stretched. At the same time, the downward movement of the L-shaped extrusion frame 710 drives the synchronous drive frame 707 to move, which in turn drives the two linkage shafts 708 to move. The linkage shafts 708 move within the drive arc groove 709, driving the rotating column 706 to rotate, which in turn drives the linkage rotating rod 704 to rotate. When the linkage rotating rod 704 rotates, it drives the cleaning brush 702 to move through the linkage sliding shaft 705, so that the cleaning brush 702 cleans the dust collection filter plate 701. This achieves automatic cleaning of the dust collection filter plate 701 during the opening and closing of the dust collection cover 602, thereby ensuring the filtration effect of the dust collection filter plate 701.
