[0002] The ladle weighing and bottom blowing system is a crucial link in the steelmaking production process. It is of great significance for the regulation of molten steel composition. Due to poor control of the steel output, it is difficult to adjust the composition. At the same time, bottom blowing is a prerequisite for adjusting the composition. The original bottom blowing system requires manual plugging and unplugging of joints, and there are safety hazards when personnel climb the ladle car. If the molten steel in the ladle boils abnormally when plugging and unplugging the joints, causing the molten steel to turn outward, personnel cannot dodge, which will cause burns or even more serious consequences.

[0004] In order to solve the above technical problems, the utility model proposes the following technical solutions:

[0005] An automatic docking device for a steel ladle with a weighing device comprises a steel ladle car base, a weighing device with a sensor is installed on the steel ladle car base, a saddle seat is installed on the steel ladle car base, a steel ladle is placed on the saddle seat, an open groove is opened in the center of the upper surface of the saddle seat, an automatic docking port is fixedly arranged in the center of the bottom surface of the steel ladle, an air intake pipe is penetrated through the bottom of the saddle seat, and the air intake pipe penetrates through the open groove, and an exhaust port is opened in the center of the automatic docking port.

[0006] Furthermore, a rubber layer is fixedly arranged in the open groove, and the automatic docking port is matched with the open groove.

[0007] Furthermore, a guide ring is fixedly provided on the upper surface of the saddle seat, and the central through hole of the guide ring is funnel-shaped with a larger diameter at the top and a smaller diameter at the bottom.

[0008] Furthermore, the inner lower diameter of the guide ring is equal to the outer diameter of the ladle.

[0009] Furthermore, a plurality of spherical grooves are provided on the inner upper inclined surface of the guide ring, and balls are rolled in the spherical grooves.

[0010] Furthermore, a circular opening is provided on the spherical groove, the diameter of the ball is larger than the diameter of the circular opening, and the ball part extends out of the circular opening.

[0011] It can be seen from the above technical solution that the beneficial effects of the utility model are:

[0012] 1. The utility model can accurately control the amount of steel discharged, which is convenient for the precise adjustment of subsequent components. The plugging and unplugging operation of the ladle bottom blowing system is no longer performed manually, which reduces the safety hazards caused by personnel climbing the ladle car and reduces the labor intensity of personnel. At the same time, it reduces the number of personnel entering the vicinity of the ladle to avoid the risk of scalding caused by abnormal boiling of molten steel, which has a higher improvement in personal safety. The device has a simple structure, is economical and practical, and is easy to install and disassemble.

[0013] 2. A guide ring is provided, the central through hole of which is funnel-shaped, so that when the ladle is hoisted above the base of the ladle car and falls, the guide ring can limit the ladle, reduce position deviation, and ensure that the automatic docking port on the ladle is aligned with the opening groove on the saddle seat.

[0014] 3. By providing the spherical groove and the ball, when the ladle is offset during the lifting process, the ladle enters above the central through hole of the guide ring, the ladle contacts the ball, and the ball rolls in the spherical groove, reducing the friction between the ladle and the guide ring. The ladle is guided by the guide ring to correct the position of the offset ladle, prevent the ladle from offsetting, and ensure that the automatic docking port on the ladle is aligned with the open slot on the saddle seat.

The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0022] See also Figure 1-3 : An automatic docking device for a ladle with a weighing device comprises a ladle car base 1, a weighing device 2 with a sensor is installed on the ladle car base 1, a saddle seat 3 is installed on the ladle car base 1, a ladle 4 is placed on the saddle seat 3, an open groove 5 is opened in the center of the upper surface of the saddle seat 3, an automatic docking port 6 is fixedly arranged in the center of the bottom surface of the ladle 4, an air intake pipe 7 is penetrated through the bottom of the saddle seat 3, and the air intake pipe 7 penetrates through the open groove 5, and an exhaust port is opened in the center of the automatic docking port 6.

[0023] In actual use, after the hot repair of the ladle 4 is completed, the personnel at the hot repair ladle post command the ladle 4 to be lifted above the base 1 of the ladle car. When the commander commands the ladle to fall to 10 cm from the base, he commands the overhead crane to slowly descend, and the automatic docking port 6 on the ladle 4 falls into the open groove 5 of the saddle seat 3 of the bottom blowing of the ladle car. The bottom blowing system is docked and ready to be put on line for steel tapping. The weighing device 2 with a sensor weighs the ladle 4 on the base 1 of the ladle car to achieve stable control of the steel tapping amount.

[0024] In this embodiment, a rubber layer is fixedly disposed in the opening groove 5 , and the automatic docking port 6 matches the opening groove 5 to ensure the sealing performance after the automatic docking port 6 and the opening groove 5 are docked.

[0025] In this embodiment, a guide ring 8 is fixedly provided on the upper surface of the saddle seat 3, and the central through hole of the guide ring 8 is funnel-shaped with a larger diameter at the top and a smaller diameter at the bottom.

[0026] In this embodiment, the inner lower diameter of the guide ring 8 is equal to the outer diameter of the ladle 4 .

[0027] By providing a guide ring 8, the central through hole of the guide ring 8 is funnel-shaped, so that when the ladle 4 is hoisted above the ladle car base 1 and falls, the guide ring 8 can limit the ladle 4, reduce position deviation, and ensure that the automatic docking port on the ladle 4 is aligned with the open groove 5 on the saddle seat 3.

[0028] In this embodiment, a plurality of spherical grooves 801 are formed on the inner upper inclined surface of the guide ring 8 , and balls 802 are rolled in the spherical grooves 801 .

The ball 802 rolls in the spherical groove 801, thereby reducing the friction between the ladle 4 and the guide ring 8. The ladle 4 is guided by the guide ring 8, and the position of the offset ladle 4 is corrected to prevent the ladle 4 from being offset, thereby ensuring that the automatic docking port on the ladle 4 is aligned with the open groove 5 on the saddle seat 3.
