[0002] Galvanized steel sheet is a welded steel sheet with a hot-dip galvanized or electro-galvanized coating on its surface. It is widely used in construction, home appliances, automobiles, ships, container manufacturing, and electromechanical industries. With the development of the domestic steel industry market, product structure adjustment, specification development and expansion, and quality upgrading have become the main research directions for steel companies. my country has been developing continuous hot-dip galvanizing technology for strip steel for nearly 30 years, and its technological level and construction scale have gradually reached an internationally leading position. Especially in the last decade or so, the number of hot-dip galvanizing production lines under construction has been increasing year by year. Galvanized products, with their high surface quality, superior corrosion resistance, and lower production costs, are gradually moving into the high-end product market.

[0003] Currently, continuous hot-dip galvanizing production lines require rolling transport of steel strips at each stage. As a result, there are a large number of roller sets used for transporting steel strips on continuous hot-dip galvanizing production lines. These roller sets need to be replaced frequently when worn or damaged. Since individual rollers are heavy, there are problems such as inconvenience in transportation and installation. In existing technologies, overhead cranes are mostly used for transportation, which is inefficient and poses safety hazards. Utility Model Content

A first adjusting plate is slidably connected to the gantry frame. A second adjusting plate is rotatably mounted on the first adjusting plate. A roller support rod is mounted on the second adjusting plate. A screw jack is mounted on the first adjusting plate. The output end of the screw jack passes through the first adjusting plate and abuts against the second adjusting plate. A drive component for raising and lowering the first adjusting plate is fixedly mounted on the top of the gantry frame. The bottom of the drive component is connected to the first adjusting plate.

[0007] As a further improvement of this utility model, the gantry frame has a sliding guide groove on its inner wall in the vertical direction.

[0008] As a further improvement of this utility model, a sliding rod that matches the sliding guide groove is fixedly connected to the top of the first adjusting plate.

[0009] As a further improvement of this utility model, a sliding ring is fixedly connected to the top of the second adjusting plate, and the sliding ring is rotatably connected to the sliding rod.

[0010] As a further improvement of this utility model, a hanging ring is fixedly installed on the top of the sliding rod, and a hook is connected to the bottom of the driving component by an iron chain or flexible rope, and the hook is hooked on the hanging ring.

[0013] As a further improvement of this utility model, a caster wheel is installed on the top of the base.

[0014] The above technical solution has the following advantages or beneficial effects:

[0015] When a roller needs to be disassembled for replacement or repair due to severe wear or malfunction, the entire assembly is moved to the vicinity of the roller using the casters. After removing the fixing structure at the end of the roller, the roller support rod is adjusted upwards using a screw jack, causing the end of the roller to enter the hollow roller support rod and press against the inside of the roller support rod. By moving the entire assembly outwards, the roller is pulled out of the galvanizing production line, thus achieving quick disassembly, facilitating maintenance or replacement, effectively improving maintenance and replacement efficiency, and reducing economic losses caused by downtime of the galvanizing production line due to roller maintenance or replacement.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0025] Reference Figures 1-4 A quick-change device for galvanizing line rollers includes a base 1 and a gantry frame 2. The gantry frame 2 is fixedly mounted on the top of the base 1. A first adjusting plate 4 is slidably connected to the gantry frame 2. A second adjusting plate 7 is rotatably mounted on the first adjusting plate 4. A roller support rod 6 is installed on the second adjusting plate 7. The roller support rod 6 is a hollow structure. A screw jack 5 is installed on the first adjusting plate 4. The output end of the screw jack 5 passes through the first adjusting plate 4 and abuts against the second adjusting plate 7. A driving component 3 for driving the first adjusting plate 4 to rise and fall is fixedly mounted on the top of the gantry frame 2. The bottom of the driving component 3 is connected to the first adjusting plate 4.

[0026] The first adjusting plate 4 is raised and lowered by the driving component 3. The first adjusting plate 4 raises and lowers the roller support rod 6 on the second adjusting plate 7. This makes it easy to adjust the roller support rod 6 to the vicinity of the roller that needs to be repaired or replaced on the galvanizing line. The second adjusting plate 7 is rotated upward by the screw jack 5, which in turn moves the roller support rod 6 upward. When changing rollers, the roller can be inserted into the roller support rod 6 to achieve stable support.

[0027] In some alternative embodiments, the gantry 2 has a sliding guide groove 9 on its inner wall in the vertical direction.

[0028] Furthermore, a sliding rod 8 that matches the sliding guide groove 9 is fixedly connected to the top of the first adjusting plate 4. The sliding guide groove 9 limits the sliding rod 8 to ensure that the sliding rod 8 can only drive the first adjusting plate 4 to move up and down in the vertical direction.

[0029] Optionally, a sliding ring 12 is fixedly connected to the top of the second adjusting plate 7. The sliding ring 12 is rotatably connected to the sliding rod 8. For example, the sliding ring 12 is movably sleeved on the outside of the sliding rod 8. When the screw jack 5 lifts the second adjusting plate 7, the sliding ring 12 rotates around the sliding rod 8, while ensuring that the second adjusting plate 7 does not separate from the first adjusting plate 4.

[0030] As an example, a hanging ring 13 is fixedly installed on the top of the sliding rod 8, and a hook 14 is connected to the bottom of the driving component 3 by an iron chain or flexible rope, and the hook 14 is hooked on the hanging ring 13.

[0031] In some alternative embodiments, the drive unit 3 is configured as one of a manual hoist, an electric hoist, or a crane motor.

[0032] For example, the drive unit 3 can be configured as a manual hoist or an electric hoist, which is connected to the hook 14 via an iron chain. Alternatively, the hook 14 can be welded to the bottom of the iron chain, and the hook 14 can be attached to the hanging ring 13 to connect the drive unit 3 to the first adjusting plate 4.

[0033] Alternatively, the drive unit 3 may be specifically configured as a lifting motor, and the flexible rope may be configured as a steel wire rope or steel strand commonly used in the prior art for lifting heavy objects. A hook 14 may be fixedly connected to the bottom of the steel wire rope or steel strand, and the drive unit 3 may be connected to the first adjusting plate 4 by hooking it onto the hanging ring 13.

[0034] In some alternative embodiments, a counterweight 10 is also provided on the side of the base 1 away from the gantry 2. The counterweight 10 is used to maintain balance. Considering that the rollers placed on the roller support rod 6 are relatively heavy, a counterweight 10 is provided on the side of the base 1 away from the gantry 2. The counterweight 10 can be a movable iron block, a concrete block, or a concrete block solidified on the base 1, etc.

[0035] In some alternative embodiments, a caster wheel 11 is mounted on the top of the base 1.

[0036] When a roller needs to be disassembled for replacement or repair due to severe wear or malfunction, the entire device is moved to the vicinity of the roller using the casters 11. After removing the fixing structure at the end of the roller, the roller support rod 6 is adjusted upwards using the screw jack 5, so that the end of the roller enters the hollow roller support rod 6 and abuts against the inside of the roller support rod 6. The roller is then pulled out of the galvanizing production line by moving the entire device outwards, thus achieving quick disassembly for easy repair or replacement. In addition, this device can also safely and quickly transport old rollers that have been disassembled for replacement or new rollers that need to be installed.

[0037] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
