Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to a cutting device for processing steel pipes on a floating oil storage vessel. Background Technology

[0002] As is well known, during the manufacturing process of floating oil storage and offloading vessels, a large number of steel pipes are used inside the vessel. The steel pipes vary in length and need to be cut by workers. Some steel pipes are cut in the factory and used directly on the hull, while others need to be cut inside the hull.

[0003] Chinese patent CN221870454U describes a ship steel pipe cutting device. This device includes a worktable with a lead screw slide on top. A rotation fixing module is located at the output end of the lead screw slide. The rotation fixing module includes a first rotation fixing component and a second rotation fixing component. The steel pipe can be rotated and cut by the synchronous rotation of the first and second rotation fixing components. However, in practical use, the following problems still exist:

[0004] During shipbuilding, some steel pipes need to be cut inside the ship's hold. Due to limited space in the hold, small cutting equipment is needed to cut the steel pipes. Generally, the steel pipe is fixed on the cutting machine and the saw blade is manually controlled to press down for cutting. However, when manually controlling the pressing down, the speed is not well controlled, resulting in unstable pressure and thus causing deviations in the cut steel pipes.

[0005] Therefore, a cutting device for processing steel pipes on floating oil storage vessels is proposed. Utility Model Content

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This is a cutting device for processing steel pipes on a floating oil storage vessel. During operation, the meshing action of a small gear and a large gear disc ensures that the large gear disc is fixed to the small gear during the worker's downward cutting process. This allows the worker to more stably control the downward cutting of the saw blade, avoiding unstable pressure caused by poor manual speed control and resulting in deviations in the cut steel pipe, thus improving the cutting accuracy. After cutting, the power unit is turned off, and the energy storage and reversing component quickly reduces the rotation of the saw blade due to inertia, thereby reducing the time the worker needs to adjust for the next steel pipe to be cut and improving work efficiency. When the saw blade is lifted, the braking component is activated to interrupt the inertial rotation of the saw disc and generate vibration, which removes burrs from the cut edge of the steel pipe.

The surface of the arc surface of the second slider 28 that contacts the protective housing ring 22 is a rough surface.

[0037] The work process is as follows:

[0038] S1. During operation, the steel pipe to be cut is fixed on the base 1 of the cutting machine. The power unit 5 is started, and the power unit 5 drives the saw blade 6 to rotate and begin cutting. The worker controls the support arm 4 to rotate around the support shaft 3 on the cutting machine bracket 2 to control the saw blade 6 to press down and cut the steel pipe. The power output shaft of the power unit 5 is rotatably connected to the burr removal component through the coupling 7. The burr removal component is fixedly connected to the pinion 9. The pinion 9 is engaged with the large gear plate 8. When the saw blade 6 rotates and the support arm 4 is not controlled to press down, the pinion 9 remains stationary. When the worker starts to control the saw blade 6 to press down and cut the steel pipe, the pinion 9 rotates on its own axis and rotates around the axis of the large gear plate 8 along the edge of the large gear plate 8. Through the meshing action of the pinion 9 and the large gear plate 8, the large gear plate 8 is fixed during the worker's pressing down and cutting process, while the pinion 9 is always in a meshing motion state. This allows the worker to control the saw blade 6 to press down and cut more stably, avoiding unstable pressure caused by poor manual speed control, which leads to deviations in the cut steel pipe and thus improves the cutting accuracy of the steel pipe.

[0039] S2, after the power assembly 5 is started, the power output shaft of the power assembly 5 drives the energy storage shaft 12 to rotate through the coupling 7. The driving ring 13, which is fixedly connected to the energy storage shaft 12, begins to rotate. At this time, the sliding block 17 is engaged in the locking groove 20 of the driven ring 14. The driven ring 14 begins to rotate and twists the torsion spring 15. When the torsion spring 15 reaches its limit, the driving ring 13 rotates and presses the inclined surface at the top of the sliding block 17, causing the sliding block 17 to slide into the sliding groove 19 and compress the slider spring 18. The saw blade 6 continues to rotate and cuts the steel pipe. When cutting and severing the steel pipe, the power assembly 5 is turned off. The slider spring 18 pushes the top of the sliding block 17 into the locking groove 20. The large gear 8 and the small gear 9 are in a meshed and fixed state. The small gear 9 is fixedly connected to the housing 11. The housing 11 is in a fixed state. The torsion spring 15 returns to its original state and drives the driven rotating ring 14 to rotate. The driven rotating ring 14 generates damping through the cooperation of the driving rotating ring 13, the energy storage rotating shaft 12, the coupling 7 and the power assembly 5, which causes the saw blade 6 to rotate rapidly. This reduces the time for workers to adjust the steel pipe to be cut next and improves work efficiency.

[0040] S3, during the cutting process, when the worker presses down on the saw blade 6, the pinion 9 drives the first slider 24 to rotate through the housing ring 23. The flat surface at the top of the first slider 24 contacts the arc surface at the bottom of the second slider 28. Since the surface of the inclined side of the first slider 24 that contacts the housing ring 23 is a rough surface, the first slider 24 squeezes the second slider 28 into the sliding groove of the protective housing ring 22 and compresses the second spring 29. When the power assembly 5 is turned off after cutting the steel pipe, the saw blade 6 decelerates rapidly, the worker lifts the saw blade 6, and the pinion 9 drives the first slider 24 to rotate through the housing ring 23. The first slider 24 reverses, and the inclined surface at the top of the first slider 24 contacts the inclined surface at the bottom of the second slider 28. The surface of the second slider 28 that contacts the protective shell ring 22 is rough. The second slider 28 squeezes the first slider 24 into the sliding groove of the shell ring 23 and compresses the first spring 25. The first slider 24 pushes the brake pad 27 to contact the energy storage shaft 12 through the connecting rod 26, so that the saw disc 6 stops. The vibration generated by the rapid stopping of the saw disc 6 terminates the inertial rotation of the saw disc 6 and removes the burrs at the cut of the steel pipe.

[0041] The large toothed disc 8 is set in a "fan" shape and is only set during the stroke formed by the saw blade 6 cutting and pressing down. This can reduce the space occupied by the large toothed disc 8 and avoid affecting the cutting of the steel pipe. The addition of the stabilizer bar 10 stabilizes the meshing state between the pinion 9 and the large toothed disc 8, further improving the worker's control of the cutting machine during cutting.
