Description

Technical Field

[0001] This utility model relates to a flipping device, and more particularly to a device capable of flipping a steel coil, belonging to the technical field of steel coil flipping equipment. Background Technology

[0002] In hot rolling production, strip steel is coiled into coils by a coiler. Whether for cold rolling, pipe making, hoisting, or transportation, the coils need to be flipped from one direction to another for ease of use, allowing them to be used on different processing equipment to meet production and processing needs. Existing coil flipping machines have a relatively simple working principle, mainly consisting of a flipping frame, support platform, coil-holding device, flipping mechanism, and control system. However, existing coil flipping machines frequently encounter the following problems in actual use: 1. Traditional support platforms have a lining plate, but with prolonged use and friction, various pits, bumps, or scratches appear on the surface, easily damaging the coil surface; 2. With changes in coil size, especially narrow coils, a large gap remains between the coil side and the coil-holding device when transported to the support platform, leading to contact limit failure and potential for dropping and impact. Therefore, existing coil flipping equipment suffers from scratching the coil surface. Thus, a coil flipping device is needed that ensures the surface of the coil remains unscratched during the flipping process. Utility Model Content

[0021] Operating principle: There are two working states. The first is to flip the horizontal steel coil into an upright state, and the second is to flip the upright steel coil into a horizontal state. The upright state of the steel coil means that the axis of the coil is perpendicular to the ground. The horizontal placement means that the coil is horizontal and the axis of the coil is parallel to the ground.

[0022] The first method, which involves flipping a horizontal steel coil to an upright position, involves the following steps:

[0023] Start the motor to adjust the position of the first and second flap assembly, so that the second flap 2 is in a horizontal state and the first flap 1 is in a vertical state. Then, hoist the steel coil onto the two idler rollers 8. Then, start the electric winch 3 to pull the connecting beam 4, so that the steel coil moves toward the first flap until the side wall of the steel coil is tightly pressed against the adjusting plate 10. Then, start the motor to drive the rotating plate 13 to rotate, which in turn drives the steel coil to rotate synchronously, so that the second flap 2 is adjusted to a vertical state until the steel coil is adjusted to an upright state. Then, remove the steel coil.

[0024] In the second case, the steel coil in the upright position is flipped into a horizontal position;

[0025] The motor is started to adjust the position of the first and second flap assembly, so that the first flap is horizontal and the second flap is vertical. Then, the upright steel coil is placed on the adjusting plate 10, at which point the side wall of the steel coil touches the horizontal adjusting plate 10. Then, the first hydraulic cylinder is started to drive the rollers on both sides to move closer to the steel coil until both rollers touch the circumferential side wall of the steel coil. If the two rollers cannot contact the steel coil at the same time, the second hydraulic cylinder 11 is started to adjust the position of the steel coil until the two rollers can contact the steel coil at the same time. Then, the motor is started to drive the steel coil to flip until the steel coil is adjusted to a horizontal position, and finally the steel coil is removed.
