Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of continuous casting machines, namely a fixing device for the ladle cover column of a continuous casting machine. Background Art
[0002] In the prior art, during the production process of a continuous casting machine, the ladle cover column hoists the ladle cover to rotate to install or remove the ladle cover for the molten steel ladle. During the rotation process of the ladle cover column, the ladle cover column shakes due to the centrifugal force generated by the ladle cover, affecting the stable operation of the equipment. Summary of the Utility Model
[0003] The purpose of the utility model is to provide a fixing device for the ladle cover column of a continuous casting machine that can prevent the ladle cover column from shaking and enable the equipment to operate stably and efficiently in view of the above deficiencies.
[0004] The technical solution of the utility model is: a fixing device for the ladle cover column of a continuous casting machine, characterized in that a fixing arm is installed between the side plate of the ladle turntable and the ladle cover column. One end of the fixing arm is connected through two fixing anchor points, and the other end of the fixing arm is connected to the ladle cover column through one fixing anchor point; each anchor point has a fixing ring, an eccentric connecting shaft, an eccentric sleeve to be connected and fastened with the fixing arm.
[0005] The advantages of the utility model are: 1. This device installs a fixing arm on the ladle cover column to limit the shaking of the column. 2. The connection between the fixing arm and the column is designed with an eccentric adjustment device. The eccentric design can conveniently adjust the position of the connecting pin shaft, eliminate the installation error of the anchor point, facilitate the connection and installation of the fixing arm, and can also eliminate the gap between the fixing arm and the connecting pin shaft through the eccentric adjustment device to achieve the purpose of locking. 3. The ladle cover column is fixed reliably, and the production and installation are convenient.
[0006] The following will further describe the embodiments of the utility model in detail with reference to the drawings. Brief Description of the Drawings

[0008] Figure 2 is the top view schematic diagram of the assembly of the eccentric adjustment device.
[0009] Figure 3 is the structural schematic diagram of the eccentric connecting shaft part.
[0010] Figure 4 is the structural schematic diagram of the eccentric sleeve part.
[0011] Figure 5 is the structural schematic diagram of the fixing ring part. Detailed Description of the Embodiment
[0012] See Figure 1-5, the names of the components are as follows: fixed arm 1, eccentric connecting shaft 2, eccentric sleeve 3, fixed ring 4, ladle turntable side plate 5, and ladle cover column 6.
[0013] See Figure 1 -5, a fixing device for the ladle cover column of a continuous casting machine. A fixed arm 1 is installed between the ladle turntable side plate 5 and the ladle cover column 6. One end of the fixed arm 1 is connected through two fixed anchor points, and the other end of the fixed arm 1 is connected to the ladle cover column 6 through one fixed anchor point; each anchor point has a fixed ring 4, an eccentric connecting shaft 2, an eccentric sleeve 3 connected and fastened to the fixed arm 1. Two anchor points are welded on the ladle turntable side plate 5 beside the ladle cover column, and one anchor point (connection point) is welded on the ladle cover column 6. The three horizontally positioned anchor points are connected and fastened through components such as the fixed arm 1, fixed ring 4, eccentric connecting shaft 2, and eccentric sleeve 3. Among them, the eccentric connecting shaft 2, eccentric sleeve 3, and fixed ring 4 are installed on each anchor point to form an eccentric adjustment device. By rotating the eccentric connecting shaft 2, the connection position of the fixed arm 1 can be adjusted to eliminate the installation error of the parts, facilitate installation, and after installation is completed, it is locked to eliminate the radial clearance between the fixed arm 1 and the eccentric connecting shaft 2.
[0014] After the equipment is improved, by installing a fixed arm 1 on the ladle turntable side plate 5 and the ladle cover column 6, and the fixed arm 1 is connected through three fixed anchor points, the ladle cover column 6 is radially fixed to limit the sway of the ladle cover column 6, so that the ladle cover lifted by the ladle cover column 6 runs stably, avoiding the phenomenon that the ladle cover impacts the ladle during the installation process due to the violent swing of the ladle cover, and improving the working efficiency of the ladle cover column.
[0015] Working principle: Through the connection of three fixed anchor points and the fixed arm 1, the radial fixation of the ladle cover column 6 is achieved. An eccentric adjustment device is composed of an eccentric connecting shaft 2, an eccentric sleeve 3, and a fixed ring 4. By rotating the eccentric connecting shaft 2, the connection position of the fixed arm 1 can be adjusted to eliminate the installation error of the parts and facilitate installation. After the installation is completed and the eccentric connecting shaft 2 is rotated and locked, the fixed ring 4 is spot-welded to the anchor point to fix the eccentric connecting shaft 2 and eliminate the radial clearance between the eccentric connecting shaft 2 and the fixed arm 1. After the eccentric sleeve 3 is assembled, it needs to be welded and fixed to the anchor point.
[0016] The above description is only the specific implementation manner of the present invention, and various examples do not constitute a limitation to the substantial content of the present invention.
