Description

Technical Field

[0001] This invention relates to the field of roller maintenance device technology, and in particular to a multifunctional roller maintenance device for pickling and galvanizing combined units. Background Technology

[0002] In pickling and galvanizing combined units, due to the use of induction heating, the furnace length is relatively short, and the number of internal turning rollers is relatively small, generally around 4-7, while the number of loose rollers in the entire unit is relatively large. If two types of furnace roller hangers (one for furnace rollers and one for loose rollers) are installed, it would be wasteful. Therefore, a device is needed that can install both internal turning rollers and loose rollers. Summary of the Invention

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] In this preferred embodiment, refer to Figures 1 to 7A multifunctional roller maintenance device for a pickling and galvanizing combined unit includes a frame 1, a mobile carriage 2, a furnace roller support frame 3, a furnace roller side bracket 4, a first drive unit 5, a second drive unit 6, and a looper roller mounting beam 7 mounted on the frame 1.

[0028] The first drive unit 5 is connected to the mobile frame 2 to drive the mobile frame 2 to move horizontally on the frame 1. The mobile frame 2 is provided with a support for placing the furnace roll cover and the furnace roll bearing seat bracket (there are two support members, which are respectively installed for the furnace roll cover and the furnace roll bearing seat bracket). The furnace roll support frame 3 and the furnace roll side bracket 4 are detachably installed on the frame 1 (such as by bolt connection) to support the two ends of the furnace internal turning roller 12. The second drive unit 6 is connected to the furnace roll side bracket 4 to drive it to move horizontally and vertically relative to the frame 1. The looper roller mounting beam 7 is detachably installed on the frame 1. A through hole is opened below the looper roller mounting beam 7 for installing the looper roller hook 9 to lift the looper roller 11.

[0029] Specifically, a rack 101 is mounted on the frame 1, and a moving gear that meshes with the rack 101 is mounted on the bottom of the mobile frame 2. The first drive device 5 operates, thereby driving the moving gear of the mobile frame 2 to move on the rack 101.

[0030] The combination of rack 101 and moving gear facilitates the movement of the mobile frame 2 and allows for precise control of the moving distance of the mobile frame 2.

[0031] Specifically, in this embodiment, the first driving device 5 includes a first motor 51 and a drive gear 52 fixedly connected to the output shaft of the first motor 51. The drive gear 52 meshes with a rack 101 on the frame 1. The rotation of the first motor 51 drives the drive gear 52 to rotate, thereby moving the mobile frame 2.

[0032] Furthermore, each side of the mobile frame 2 is equipped with a drive gear 52 (one drive gear 52 on each side), and two racks 101 are mounted on the frame 1. The two racks 101 cooperate with the drive gears 52 on both sides of the mobile frame 2 to achieve stable movement of the mobile frame 2.

[0033] This embodiment presents a specific structure of the second driving device 6: the second driving device 6 includes a furnace roller support lifting device 61 and a roller support driving device 62, wherein the furnace roller support lifting device 61 includes a furnace roller bottom support 611 located below the furnace internal turning roller 12 to support it, and a fixed base 612 slidably mounted on the frame 1, and the tail end of the furnace roller bottom support 611 ( Figure 1The right end shown is hinged to the fixed base 612. The bottom of the furnace roller side bracket 4 is fixedly connected to the middle of the furnace roller bottom bracket 611. The roller frame drive device 62 is connected to the fixed base 612 to drive it to move horizontally relative to the frame 1.

[0034] Furthermore, the furnace roll support lifting device 61 also includes a lifting drive mechanism for driving the furnace roll bottom support 611 to rotate relative to the fixed base 612, the lifting drive mechanism causing the furnace roll bottom support 611 to rise or fall. In this embodiment, the lifting drive mechanism is a hydraulic drive device 63.

[0035] Specifically, the roller frame drive device 62 includes a second motor, a drive sprocket fixed on the output shaft of the second motor, a first chain sleeved on the transmission wheel, and a driven sprocket located in the first chain. The driven sprocket is connected to the fixed base 612 through the second chain. The rotation of the second motor drives the drive sprocket to rotate, and the driven sprocket is driven to rotate through the first chain transmission, thereby driving the fixed base 612 to move horizontally relative to the frame 1, and thus driving the furnace internal turning roller 12 to move horizontally.

[0036] Reference Figure 7 This embodiment presents a specific structure for a looper roller mounting beam 7: the looper roller mounting beam 7 includes a support plate 71 mounted on the frame 1 and two connecting plates 72 passing through the frame 1, with through holes on the connecting plates 72. The connecting plates 72 are connected to the bottom by pins and looper roller hooks 9. The support plate 71 is mounted to the frame 1 by bolts.

[0037] Furthermore, a counterweight device 8 is also installed on the frame 1. The counterweight of the counterweight device 8 is adjusted according to the weight of the turning roller 12 inside the furnace, so that the entire maintenance device is in a balanced state when lifted.

[0038] The working principle of this multi-functional roller maintenance device is explained below.

[0039] Method 1: During installation, the furnace internal turning roller 12.

[0040] When installing the furnace inward turning roller 12, the furnace inward turning roller 12 is hoisted onto the maintenance device using a workshop crane. The furnace roller support frame 3 and the furnace roller side bracket 4 work together to support both ends of the furnace inward turning roller 12. The furnace roller cover and furnace roller bearing seat bracket are fixed to the moving frame 2 with bolts. The counterweight of the counterweight device 8 is adjusted to ensure the entire maintenance device is balanced during hoisting. Then, the maintenance device is hoisted to the furnace roller installation waiting position using the workshop crane. The left side furnace roller support frame 3 is then removed, and the furnace roller side bracket 4 and furnace roller bottom bracket 611 are driven by the second drive device 6 to transport the furnace inward turning roller 12 into the furnace. Since the relative elevation of the furnace inward turning roller 12 needs to be adjusted during installation, the height of the furnace roller bottom bracket 611 is also adjusted (via the hydraulic drive device 63) as the furnace inward turning roller 12 enters the furnace, thereby changing the installation elevation of the furnace inward turning roller 12. After the furnace guide roller 12 is installed in place, the first drive device 5 drives the moving frame 2 to run on the rack 101 of the frame 1, installing the furnace roller cover and bearing seat bracket loaded on the moving frame 2 into place. At this point, the entire furnace roller installation is complete. To disassemble the furnace roller, simply reverse the above process.

[0041] Method 2: Install looper roller 11.

[0042] After disassembling the furnace roll support frame 3 and the furnace roll side bracket 4, the loose roller mounting beam 7 is bolted to the frame 1. The connecting plate 72 of the loose roller mounting beam 7 is connected to the loose roller hook 9 by pins. The maintenance device lifts the loose roller 11 using the loose roller hook 9. To ensure the balance of the entire maintenance device during lifting, a lifting rope 10 is added. The maintenance device is lifted by a workshop crane, and the loose roller 11 is installed in place. Disassembling the loose roller 11 is achieved by reversing the above process.

[0043] The multifunctional roller maintenance device for pickling and galvanizing combined units proposed in this invention can be used for the installation and disassembly of furnace rollers in the furnace area, as well as for the installation and disassembly of the unit's looper rollers 11. Furthermore, this multifunctional roller maintenance device has the advantages of simple structure, ease of implementation, and stable and reliable operation.

[0044] The above are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural transformations made based on the description and drawings of the present invention, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
