Description

Technical Field

[0001] The present invention relates to the technical field of large-scale cylinder hole opening, in particular to a cutting device. Background Art

[0002] During the layout and installation of piping systems in the marine and offshore engineering sectors, the presence of diagonal piping is unavoidable to better manage space and effectively prevent interference between piping and cables between different systems within the space. This diagonal piping creates an elliptical cross-section as it passes through the ship's decks and bulkheads. Therefore, during the hull fabrication process, it is often necessary to create elliptical holes in the decks and bulkheads to facilitate piping placement and welding.

[0003] The traditional method of drilling an elliptical hole is to draw a standard circle on the deck using a compass or other tools based on the outer diameter of the oblique pipe penetration, and then punch a punch point. Then, based on this circle, gas cutting operations are gradually performed to continuously expand the drilling area, forming a non-standard elliptical hole with a relatively rough appearance. The non-standard elliptical hole is then polished and repaired.

[0004] Existing elliptical holes are all drilled manually, which requires a lot of labor costs. At the same time, large errors are easily caused by human factors during the drilling process, resulting in rework or even scrapping of the entire drilling area, which in turn affects subsequent welding work and even the construction quality and efficiency of the entire ship.

[0060] In the optional technical solution of this embodiment, the first adjustment bracket 11 and the second adjustment bracket 15 both include a posture adjustment mechanism 16, a magnetically fixed universal adjustment foot 17 and a range adjustment mechanism 18; the posture adjustment mechanism 16 is respectively connected to the magnetically fixed universal adjustment foot 17 and the range adjustment mechanism 18, the range adjustment mechanism 18 is used to connect the mounting plate, and is used to drive the posture adjustment mechanism 16 to move horizontally, and the posture adjustment mechanism 16 is used to drive the range adjustment mechanism 18 to move up and down.

[0061] In this embodiment, the posture adjustment mechanism 16 is fixed by a magnetically fixed universal adjustment foot 17, and the magnetically fixed universal adjustment foot 17 has a universal adjustment function, so that the posture adjustment mechanism 16 can be tilted at will, avoiding damage to the posture adjustment mechanism 16 due to stress. The range adjustment mechanism 18 is connected to the mounting plate, where the mounting plate can be the first mounting plate 9 or the second mounting plate 13; the range adjustment mechanism 18 drives the posture adjustment mechanism 16 to move horizontally, and the posture adjustment mechanism 16 drives the range adjustment mechanism 18 to move up and down, that is, when the range adjustment mechanism 18 drives the posture adjustment mechanism 16 to move horizontally, the posture adjustment mechanism 16 approaches or moves the mounting plate in the horizontal direction, and the posture adjustment mechanism 16 drives the range adjustment mechanism 18 to move up and down, and the mounting plate rises or falls. The overall structure is simple, not only can the range be adjusted, but also the posture can be adjusted, the adjustment is diversified, and the applicability is high.

[0062] In an optional technical solution of this embodiment, the range adjustment mechanism 18 includes a sleeve 19 and a slide rod 20. The sleeve 19 is connected to the mounting plate. One end of the slide rod 20 is inserted into the sleeve 19 and slidably connected thereto, achieving the telescopic effect. The other end of the slide rod 20 is connected to the posture adjustment mechanism 16. Specifically, a slot is provided on one side of the sleeve 19. After the slide rod 20 is inserted into the sleeve 19, it is tightened with a quick-locking screw to hold the slide rod 20. Keyways are provided on both the slide rod 20 and the sleeve 19, ensuring that they are connected and prevent rotation after clamping. This simple structure provides convenient and stable lateral adjustment and easy installation and removal.

[0063] In the optional technical solution of this embodiment, the posture adjustment mechanism 16 includes an adjusting rod 21, an adjusting guide sleeve 22 and an adjusting knob 23; the adjusting rod 21 is passed through the adjusting guide sleeve 22, the adjusting guide sleeve 22 is connected to the range adjustment mechanism 18, and the adjusting knob 23 is arranged on the adjusting guide sleeve 22; the adjusting rod 21 is provided with a first gear tooth, and the adjusting knob 23 is provided with a second gear tooth engaged with the first gear tooth.

The adjustment rod 21 is provided with a first gear, and the adjustment guide sleeve 22 is mounted with an adjustment knob 23 with a second gear. The second gear on the adjustment knob 23 meshes with the first gear on the adjustment rod 21. Rotating the adjustment knob 23 drives the adjustment guide sleeve 22 to move on the adjustment rod 21. This simple structure provides stable and convenient adjustment.

[0065] In this embodiment, the lower end of the adjustment rod 21 is connected to the magnetically fixed universal adjustment foot 17. The magnetically fixed universal adjustment foot 17 is a magnetic universal mechanism containing a cylindrical body containing a magnet or a permanent magnet, and an external base made of soft magnetic material. Soft magnetic materials are easily magnetized in weak magnetic fields, but they are also easily demagnetized. By turning the external handle, the internal magnet can be rotated. When the poles of the magnet are facing the soft magnetic base, the base becomes magnetized, exhibiting strong magnetism, allowing it to adhere to steel surfaces. When the poles of the magnet are horizontal, the base becomes almost non-magnetic, allowing for easy removal of attached objects. Furthermore, the magnetically fixed universal adjustment foot 17 features a universal arm that can be fixed at any angle, making it quick and easy to use. Its magnetic base has a strong suction force, typically reaching 2-100 kg or even higher. Furthermore, a fine-tuning device is provided at the clamping surface to allow for arbitrary directional positioning.

When adjusting the posture adjustment mechanism 16, first loosen the hand-tightening nut, and then rotate the adjusting knob 23 on the adjusting guide sleeve 22 to realize the lifting and lowering of the adjusting guide sleeve 22, that is, the lifting and lowering of the posture adjustment mechanism 16. Due to the existence of the rotating pair, the posture adjustment mechanism 16 will also produce displacement along the direction of the slide sleeve 19 and the slide rod 20, thereby avoiding damage to the range adjustment mechanism 18 and the posture adjustment mechanism 16 due to stress, while ensuring the stability of the overall connection.

[0068] In this embodiment, the first adjustment bracket 11 and the second adjustment bracket 15 also include a sub-arm 38. One end of the sub-arm 38 is rotatably connected to the slide rod 20 to form a rotating pair, and the other end of the sub-arm 38 is connected to the adjustment guide sleeve 22 to form a rotating pair. The sub-arm 38 also has the effect of the above-mentioned rotating arm 24, which will not be repeated here.

[0075] The cutting equipment is assembled into the first form or the second form according to the specific working conditions. The specific working process is: first reserve the template line and the center of the circle at the position where the hole needs to be opened, move the cutting equipment to the position where the hole needs to be opened, and fix it by magnetically fixing the universal adjustment foot 17; coincide the axis center of the Z axis with the center of the circle, and adjust the cutting radius of the flame cutting torch 1 to be consistent with the radius of the hole to be opened through the cutting aperture adjustment device 2; perform the hole opening circle action, and adjust the cutting equipment so that the laser point of the laser rangefinder always falls on the template line and moves along the template line during one rotation of the laser rangefinder; measure the height data of the laser emission point and the cutting surface position at each angle by rotating the laser rangefinder for one rotation to perform hole opening simulation, check whether the opening trajectory coincides with the template line, and start the cutting equipment to actually cut the hole after they coincide.
