DETAILED DESCRIPTION

[0016] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings.

[0017] like Figure 1 As shown, a rolling and turning table suitable for cleaning excess materials in large cylinder sections includes a supporting and rolling mechanism 1 and a pitching mechanism 2.

[0018] like Figure 2 , Figure 3As shown, the support and rolling mechanism 1 includes a rolling base 1-1, a retaining ring 1-2, an adapter ring 1-3, a rolling ring 1-4, a rolling electric push rod 1-5, a large gear 1-6, a small gear 1-7, a worm gear reducer 1-8, a servo motor 1-9, an electromagnetic clutch 1-10, a hinge support 1-11, a reducer bracket 1-12, a lock 1-13, a rolling support 1-14, and a roller 1-15. The adapter ring 1-3 is respectively screwed and fixed to the front and rear end faces of the barrel section, the front and rear rolling rings 1-4 are respectively screwed and fixed to the front and rear adapter rings 1-3, and the large gear 1-6 is connected and fixed to the front rolling ring 1-4; the above is installed as a whole on the rolling base 1-1, and the installation positions of the two rolling rings 1-3 correspond to the front and rear semicircular saddles of the rolling base 1-1 respectively; the two clamping rings 1-2 are installed with the rolling base 1-1 in the form of hinges, and the hinge installation ends of the clamping rings 1-2 and the rolling base 1-1 are provided with a rolling electric push rod 1-5, and the other end of the rolling electric push rod is installed on the hinge support 1-11, and the hinge support 1-11 is screwed and fixed to the rolling base 1-1, and the rotary motion of the clamping ring 1-2 is transmitted through the rolling electric push rod 1 -5 drive, which can realize rotation in the range of 0 to 100°; the lock buckle 1-13 is respectively installed on the retaining ring 1-2 and the rolling base 1-1. When the rolling mechanism 1 is working, the lock buckle 1-13 is ensured to be in a locked state; the worm gear reducer 1-8 is installed on the reducer bracket 1-12, and the reducer bracket 1-12 is screwed and fixed on the rolling base 1-1, the servo motor is installed at the input end of the worm gear reducer 1-8, and the pinion 1-7 is installed at the output end of the worm gear reducer 1-8. After the servo motor 1-9 is decelerated and amplified by the worm gear reducer 1-8, it drives the pinion 1-7 to drive the large gear 1-6 to rotate, thereby driving the rolling ring 1-4, the adapter ring 1-3 and the barrel section load to rotate together. The rolling base 1-1 and the clamping ring 1-2 are symmetrically arranged with multiple groups of rollers 1-15 along the annular direction to support the barrel section as a whole and roll relative to the rolling ring 1-4 to reduce the rolling friction resistance. The end faces of the rollers 1-15 on both sides are tapered to facilitate positioning during hoisting before cleaning, and can be reliably supported when flipped at any angle. An electromagnetic clutch 1-10 is arranged between the pinion 1-7 and the output shaft of the worm gear reducer 1-8.

When it is installed in place, the electromagnetic clutch 1-10 is powered on and attracted; two rolling supports 1-14 are respectively installed at both ends above the table of the rolling base 1-1, perpendicular to the direction of the rolling axis.

The pitch axis 2-2 and the flip link 2-3, the pitch base 2-1 and the roll support 1-14 all transmit torque through the double key 2-7. The pitch base 2-1 provides support for the pitch axis 2-2, and a pair of cylindrical roller bearings 2-8 are installed between them to withstand large radial forces. The pitch mechanism 2 drives the flip link 2-3 and the roll support 2-1 to move through two sets of pitch electric push rods 2-4, thereby driving the roll base 1-1 of the roll mechanism 1 to achieve flip movement. The action points of the two sets of pitch electric push rods 2-4 on the flip link are arranged at 90 degrees to prevent both from having movement dead points at the same time, and can ensure mechanical self-locking at any position of movement to ensure safe operation. In addition, proximity switches and mechanical limit columns are respectively arranged at the extreme positions to prevent accidents caused by runaway.

[0021] The following is a detailed description of the specific application of the present invention, which is a rolling turning table suitable for cleaning excess materials in a large barrel section.

[0022] The rolling mechanism 1 is located in a horizontal position, and by driving the rolling electric push rod 1-5 to contract, the retaining ring 1-2 is in a fully open position. At this time, the pinion 1-7 and the electromagnetic clutch 1-10 are in a power-off and separated state. Fix a barrel section to the adapter ring 1-3, rolling ring 1-4 and large gear 1-6 with screws; lift the barrel section load and move it above the turntable, and visually check that it is roughly centered; the barrel section slowly descends, and when the large gear 1-6 approaches the small gear 1-7, visually check whether their end faces overlap and whether the distances between the large gear 1-6 and the two small gears 1-7 are the same. If they are different, adjust the position of the barrel section; after the adjustment, the barrel section continues to descend, and at this time the small gear 1-7 contacts the large gear 1-6 to follow and provide guidance; the barrel section falls until it contacts the side of the roller 1-15, and it can be automatically guided until it falls completely; the rolling electric push rod 1-5 is extended to make the retaining ring 1-2 move and close; the lock buckle 1-13 fixes the retaining ring 1-2 to the rolling base 1-1, and the rolling electric push rod 1-5 is powered off.

[0023] The control pinion 1-7 and the electromagnetic clutch 1-10 are in the engaged state, and the servo motor 1-9 is controlled to rotate. After the servo motor 1-9 is decelerated and increased in force by the worm gear reducer 1-8, the pinion 1-7 drives the large gear 1-6 to rotate, thereby driving the rolling ring 1-4, the adapter ring 1-3 and the barrel section to rotate together. Since the worm gear reducer 1-8 has a mechanical self-locking function, the rolling mechanism 1 can be stopped at any angle.

[0024] The two sets of pitch electric push rods 2-4 are controlled to extend or shorten to drive the rolling base 1-1 of the rolling mechanism 1 to achieve flipping movement. The action points of the two sets of pitch electric push rods 2-4 on the flip connecting rod are arranged at 90° to prevent both from having movement dead points at the same time, and can ensure mechanical self-locking at any position of movement to ensure safe operation.

[0025] To sum up, the rolling and turning table suitable for cleaning excess materials in large cylinder sections of the present invention can realize two-degree-of-freedom movement of rolling and pitching for large cylinder sections of different specifications, thereby realizing effective removal of excess materials in the cylinder sections. Its structural design is reasonable and reliable, easy to lift and install, and the pitching space size is small, which greatly improves the efficiency of the lifting operation.

[0026] The above are only the main features, working principles and advantages of the present invention. For those skilled in the art, the present invention is not limited to the above embodiments. Without violating its basic principles, the present invention can be flexibly modified and changed for different embodiments. These modifications and changes, if within the spirit and scope of the present invention, should all fall within the protection scope of the present invention.
