Description

Technical Field

[0001] The utility model relates to the technical field of ladle pouring equipment, in particular to a carbon rod control mechanism. Background Art

[0002] Casting refers to the process of pouring molten metal into a specific mold for solidification. Generally speaking, casting is divided into manual casting and automatic casting. The principle is to use a mold to pour liquid metal, and after the metal solidifies, a casting with a certain shape and size can be obtained. Steel casting includes a ladle casting machine, which is an automatic casting equipment that uses an automatic control system for casting.

[0003] The ladle pouring equipment includes a ladle, and in order to control the opening and closing of the ladle mouth, a carbon rod is often set to block the ladle mouth, but many of them are manually operated mechanical structures to block the carbon rod. Even if some carbon rods are driven by machines, the driving mechanism of these carbon rods is relatively simple. Most of them are driven by cylinders, but the cylinders cannot accurately position and provide real-time feedback. Moreover, sometimes when the equipment is powered off, some carbon rods with simple structures cannot fall in time, so that the ladle mouth cannot be closed in time. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3, a carbon rod control mechanism, comprising a column body 1, a lifting protection box 3 is slidably arranged on the side wall surface of one side of the column body 1, a driving protection box 4 is arranged on the upper end surface of the lifting protection box 3, and a lifting mechanism 9 is arranged in the lifting protection box 3;

The servo electric cylinder 10 includes a drive rod 101 arranged at the bottom output end. The drive rod 101 extends into the bottom lifting protection box 3, and the other end of the drive rod 101 away from the output end of the servo electric cylinder 10 is fixedly connected to the upper surface of the first mounting plate 93. The servo electric cylinder 10 drives the lifting mechanism 9 to lift and lower, thereby realizing the lifting and lowering of the carbon rod on the claw 7.

[0025] Moreover, a safety cylinder 8 is provided on the side wall surface of the column body 1 where the lifting protection box 3 is provided. The safety cylinder 8 is provided at the bottom of the lifting protection box 3, and the piston rod body at the upper end of the safety cylinder 8 is connected to the bottom end surface of the lifting protection box 3. After the power is cut off, the telescopic rod of the safety cylinder 8 will automatically fall down, so that the lifting protection box 3 will drop as a whole, thereby automatically blocking the pouring mouth of the ladle with the carbon rod to prevent safety problems.

When working, the servo electric cylinder 10 drives the driving rod 101 to move, so that the first mounting plate 93 drives the sliding column 92 and the second mounting plate 94 to slide on the sliding rod 91, thereby realizing the lifting of the carbon rod installed at the claw 7 on the second mounting plate 94, and the effect of controlling the flow rate of molten iron is achieved by adjusting the height of the carbon rod.

[0028] And compared with the hydraulic cylinder drive, the servo electric cylinder 10 has its irreplaceable advantages. The servo electric cylinder 10 can provide more precise positioning and fast real-time feedback, which increases the service life of the ladle carbon rod and the feel during operation to a certain extent.

[0029] In addition, the safety cylinder is set to ensure that when the equipment is powered off, the safety cylinder will automatically fall, thereby realizing the overall fall of the lifting protection box 3, so that the carbon rod can close the ladle pouring mouth in time, thereby preventing the equipment safety problem caused by the ladle pouring mouth not being able to be closed in time when the equipment is powered off.
