Description

Technical Field

[0001] This utility model belongs to the field of metallurgical smelting technology, and in particular relates to a long nozzle centering robot for continuous casting. Background Technology

[0002] The alignment and connection between the long nozzle for continuous casting and the ladle nozzle is crucial for the protective casting process. Argon sealing is used to protect the long nozzle and the ladle nozzle. However, if the long nozzle and the ladle nozzle are not aligned, the gap will be too large. As a result, the large negative pressure generated when the molten steel flows during the production process will cause air to be drawn into the gap between the long nozzle and the ladle nozzle, resulting in secondary oxidation of the molten steel.

[0003] Currently, robotic arms are used for the displacement and alignment of long nozzles. However, this is done using a single linear alignment method, which may result in alignment in the linear direction but misalignment in other two-dimensional directions, leading to poor alignment performance. Summary of the Invention

[0004] The purpose of this invention is to provide a long nozzle centering robot for continuous casting. By setting a connecting rod on the outside of the arm, one end of the connecting rod is connected to the end of the arm near the long nozzle, and the other end is a free end. In the actual centering process, one person operates the adjustment seat and the other person operates the free end of the connecting rod. Compared with the original robot, the two-person operation can add an aiming direction for adjusting the long nozzle. At the same time, fine adjustment can be made through the connecting rod, which greatly improves the centering accuracy.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a long nozzle centering robot for continuous casting, including an arm and a connecting rod body. One end of the arm is connected to an adjustment seat, and the other end of the arm is fixed with a long nozzle holder.

[0007] A lifting ring is fixed to the circumference of the arm near the long water inlet bracket;

[0008] One end of the connecting rod is connected to the lifting ring via a fastener, and the other end of the connecting rod is a free end;

[0009] The boom has a hoop fixed to its circumferential side opposite to the lifting ring, and the hoop has an L-shaped hook point fixed to its circumferential side with the opening side of the hook point facing upward.

[0010] The distance between the hook point and the lifting ring is less than the length of the connecting rod, and the connecting rod is movably positioned within the hook point.

[0011] Furthermore, the adjusting seat includes a rotary table, on which a column is fixed, and a telescopic device is rotatably connected to the top of the column. One end of the boom is connected to the telescopic device, and a lifting cylinder is provided between the telescopic device and the column.

[0012] Furthermore, the column is an inverted U-shaped frame, and the tail end of the lifting cylinder is disposed inside the column and is rotatably connected to the column via a shaft.

[0013] Furthermore, the rotary table consists of a fixed part and a rotating part, the rotating part being rotatably connected to the fixed part via a slewing bearing, and the column being fixed to the top of the rotating part.

[0014] Furthermore, the end of the connecting rod away from the fastener is integrally connected to a rod head.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model features a connecting rod on the outside of the boom. One end of the connecting rod is connected to the end of the boom near the long sprue, while the other end is a free end. During actual alignment, one person operates the adjustment seat while the other person operates the free end of the connecting rod. Compared to the original robotic arm, this two-person operation adds an aiming direction for adjusting the long sprue. At the same time, fine adjustments can be made through the connecting rod, greatly improving the alignment accuracy.

[0017] 2. This utility model, through the design of the hook point with the open end of the hook point facing upward, allows the connecting rod to be quickly stored by gravity after use, without affecting the normal use of the arm.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
