Description

Technical Field

[0001] The present invention relates to the technical field of electromagnetic slag driving for zinc pots in galvanizing lines, and in particular to a mounting arm for an electromagnetic slag driving device for a zinc pot. Background Art

[0002] Electromagnetic slag displacers are installed on both sides of the zinc pot in a continuous galvanizing line to move the molten zinc and direct the slag to a desired location. The zinc pot is typically overhauled every two weeks, requiring the removal of equipment such as the sinking rollers, stabilizing rollers, and air knives. When not in use, the zinc pot needs to be kept warm, and a lid is placed above the zinc surface. Typically, the slag displacer must be removed and hoisted away, but installing and disassembling it with a fixed mounting arm is inconvenient, time-consuming, and labor-intensive.

[0003] Among existing patents and technologies, CN216919375U (application number 202122986366.9, publication date July 8, 2022) discloses a device for dynamically electromagnetically driving zinc pot surface slag removal. This device uses a robotic arm with a rotating shaft to dynamically control the movement of the slag remover. An electromagnetic slag remover weighs approximately 200 kg and carries a heavy load, requiring a bulky robotic arm. This installation method is complex and requires controllers such as motors. This device presents challenges such as heavy loads, complex control, high costs, and insufficient on-site installation space, making implementation difficult.

[0004] CN218115549U (application number 202220300823.6, publication date 2022-12-23) discloses a positionable electromagnetic slag dislodging device for a zinc pot. The electromagnetic slag dislodger is fixed to an adjustable slide rail and a telescopic rod of a telescopic mechanism. The slag dislodger can be used to move the pot. A typical zinc pot is 3 to 5 meters long, and the electromagnetic slag dislodger weighs approximately 200 kg. The heavy load of the adjustable slide rail and telescopic mechanism complicates their implementation, resulting in a large size. This device suffers from complex equipment, large size, and insufficient installation space, making it difficult to implement. Summary of the Invention

[0024] like Figure 1-5 As shown, the mounting arm of a zinc pot electromagnetic slag drive according to an embodiment of the present invention includes a mounting base 2, a mounting support arm 1 3 and a mounting support arm 2 4.

[0025] In the embodiment, a working limit block 23 is provided at the inner front end of each of the relative base support arms 22 , and a maintenance limit block 24 is provided at the inner rear end of each of the relative base support arms 22 .

[0026] In the embodiment, the upper portion of each base support arm 22 is provided with an axial hole 223 for the rotation shaft 31 to pass through, and the lower portion of the axial hole 223 is provided with a left-right symmetrical working pin hole 221 and an inspection pin hole 222, and each base support arm 22 is also provided with a fixing screw 25 on the front and rear end surfaces.

[0027] In the embodiment, two sides of the bottom end of the mounting arm 3 are provided with shaft holes 323 for the rotation shaft 31 to pass through, and the shaft hole 323 is movably connected to the shaft hole 223 through the rotation shaft 31. A pin hole 322 is provided below the shaft hole 323, and the protruding structure 321 at the lower end of the mounting arm body 32 of the mounting arm 3 is in contact with the working limit block 23 and the maintenance limit block 24 of the mounting base 2.

[0028] In the embodiment, when the mounting arm 3 rotates to the working position, the pin hole 322 is fixedly connected to the working pin hole 221 through a limiting pin shaft 26; when the mounting arm 3 rotates to the maintenance position, the pin hole 322 is fixedly connected to the maintenance pin hole 222 through the limiting pin shaft 26.

[0029] In the embodiment, a working pin hole 2 324, an inspection pin hole 2 325 and an axis hole 326 that are interconnected are provided on both sides of one end where the mounting arm 1 3 is connected to the mounting arm 2 4. The working pin hole 2 324 and the inspection pin hole 2 325 are located on the left and right sides of the corresponding axis hole 326. Limit blocks 36 are provided on both sides of the mounting arm 1 3 above the axis hole 326. The limit blocks 36 are provided with a limit slider 33 through a limit bolt 34.

[0032] In order to facilitate understanding of the above technical solutions of the present invention, the above technical solutions of the present invention are described in detail below through specific usage methods.

[0033] In specific use, the mounting arm of the zinc pot electromagnetic slag remover according to the present invention includes a mounting base 2, wherein an axis hole 1 223 is provided on the base support arm 22, which is connected to the mounting support arm 1 3 via a rotating shaft 1 31. The mounting support arm 2 4 is connected to the mounting support arm 1 3 via a rotating shaft 2 41. The electromagnetic slag remover 5 is mounted on the mounting support arm 2 4. The mounting base 2, the mounting support arm 1 3, the mounting support arm 2 4, the limit block and the limit pin 1 26 and the limit pin 2 42 enable the rotation and positioning of the mounting support arm 1 3 and the mounting support arm 2 4, thereby enabling the electromagnetic slag remover 5 to switch between the working position and the maintenance position.

[0034] The mounting base 2 includes a base support arm 22, a working limit block 23, an inspection limit block 24, a set screw 25, a limit pin shaft 26 and an axis stop plate 27. The base support arm 22 is provided with a working pin hole 221, an inspection pin hole 222 and an axis hole 223.

[0035] The second axial hole 323 of the mounting arm 3 is connected to the axial hole 223 of the mounting base 2 via the rotating shaft 31. The protruding structure 321 of the mounting arm body 32 of the mounting arm 3 contacts the working stop block 23 and the inspection stop block 24 of the mounting base 2, limiting the rotation angle of the mounting arm 3 to 0° to 180°. When the mounting arm 3 rotates to the working position, its pin hole 322 coincides with the working pin hole 221 of the base arm 22. The stop pin 26 secures the mounting arm 3, restricting its rotation and keeping it in the working position. When the mounting arm 3 rotates to the inspection position, its pin hole 322 coincides with the inspection pin hole 222 of the base arm 22. The stop pin 26 secures the mounting arm 3, restricting its rotation and keeping it in the inspection position.

[0036] The mounting arm body 1 32 of the mounting arm 1 3 is provided with a second working pin hole 324, a second inspection pin hole 325 and a third shaft hole 326. The mounting arm 1 3 is provided with a limit slider 33, a limit block 36 and a limit bolt 34.

[0037] The mounting arm body 2 43 of the mounting arm 2 is provided with a working pin hole 3 433, a maintenance pin hole 3 432 and a shaft hole 431. The shaft hole 431 of the mounting arm 2 4 is connected to the shaft hole 3 326 of the mounting arm 1 3 through the rotating shaft 2 41.

[0038] The limiting slider 33 is adjusted by the limiting bolt 34 to slide toward the inspection position, and the mounting arm 2 is rotated to make the inspection pin hole 2 325 of the mounting arm body 1 32 of the mounting arm 1 3 coincide with the inspection pin hole 3 432 provided on the mounting arm body 2 43 of the mounting arm 2 4. The fixing of the limiting pin shaft 2 42 restricts the rotation of the mounting arm 2 4, and the mounting arm 2 4 is restrained in the inspection position. The limiting slider 33 is slid toward the working position, and the mounting arm 2 is rotated to make the working pin hole 2 324 of the mounting arm body 1 32 of the mounting arm 1 3 coincide with the working pin hole 3 433 provided on the mounting arm body 2 43 of the mounting arm 2 4. The fixing of the limiting pin shaft 2 42 restricts the rotation of the mounting arm 2 4, and the mounting arm 2 4 is restrained in the working position.

[0039] The working principle is as follows: The electromagnetic slag remover is mounted on mounting arm 2 4, which is connected to mounting arm 1 3 via rotating shaft 2 41 and can rotate. The rotation angle is limited by the limit slider 33 and the limit block 36. After reaching the limited position, it is also locked in place by the limit pin 2 42. Similarly, mounting arm 1 3 is connected to mounting base 2 via rotating shaft 1 31, so that mounting arm 1 3 can rotate relative to mounting base 2, while mounting base 2 is fixed. The rotation of mounting arm 1 3 and mounting arm 2 4 realizes the working position and maintenance position of the slag remover. In the working position, the slag remover is placed above the zinc liquid level in the zinc pot, and in the maintenance position, the slag remover is placed above the zinc pot.

[0040] Rotate and install arm 13, remove limit pin 26 from working pin hole 1 221, and after rotating and installing arm 13, insert limit pin 26 into inspection pin hole 1 222; move limit slider 33, take out limit pin 2 42; remove limit pin 2 42 from working pin hole 3 433, and after rotating and installing arm 2 4, insert limit pin 2 42 into inspection pin hole 3 432, so that the electromagnetic slag drive reaches the inspection position.

[0041] To sum up, with the help of the above-mentioned technical solution of the present invention, by rotating and fixing the rotating mounting arm one and the mounting arm two, the electromagnetic slag drive can be quickly switched between the working position and the maintenance position, thereby improving the efficiency of disassembling and lifting the slag drive and reducing labor intensity.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
