Description

Technical Field

[0001] This utility model relates to the field of submerged roller technology, specifically a submerged roller with an anti-corrosion layer. Background Technology

[0002] Submerged rolls can withstand large loads and have low frictional resistance. They are mainly used for transporting and installing long, strip-shaped and similar structures. Submerged rolls play a crucial role in processes such as hot-dip galvanizing and cooling of hot-rolled strip steel. By rolling materials such as strip steel, submerged rolls can not only help control the width and thickness of the materials, but also achieve the purpose of accelerating cooling or efficient transport.

[0003] Submerged rolls face various challenges in harsh working environments such as hot-dip galvanizing and hot rolling, including high temperatures, molten metal corrosion, and mechanical wear. To improve the corrosion resistance and service life of submerged rolls, one or more layers of anti-corrosion coatings are usually sprayed on their surface. These anti-corrosion layers can isolate the submerged roll from direct contact with corrosive media, thereby slowing down the corrosion rate and protecting the base material of the submerged roll from damage.

[0004] Submerged rolls with anti-corrosion coatings are susceptible to damage during prolonged use due to factors such as corrosion from high-temperature molten zinc, abrasion from slag, and friction from the strip steel. If the damage to the anti-corrosion coating is not detected and repaired in time, the damaged coating will make it easier for molten zinc to adhere to the surface of the submerged roll during subsequent hot-dip galvanizing, forming zinc dross. A large amount of zinc dross adhering to the roll surface will lead to defects in the roll printing quality. Therefore, a submerged roll with an anti-corrosion coating is proposed to address the above problems. Utility Model Content

[0024] Please see Figure 1-5 This utility model provides a technical solution:

[0025] A submersible roller with an anti-corrosion layer includes a support frame 1, a roller body 2, and an anti-corrosion layer 3. The roller body 2 is installed on one side of the support frame 1, and the anti-corrosion layer 3 is bonded to the outer side of the roller body 2. A cleaning component 4 is provided at the lower end of the anti-corrosion layer 3. A connecting rod assembly 5 is installed inside the cleaning component 4, and a detection component 6 is fixedly connected to one end of the connecting rod assembly 5.

A film 45 is installed inside the installation groove 42, and an airbag 46 is fixedly connected inside the film 45. A perforated baffle 47 is installed inside the installation groove 42, and a perforated baffle 47 is opened on one side. The baffle slot 48 has a through hole 49 on the inner side of the perforated baffle 47. The connecting rod assembly 5 includes a rod head 51, a pin 52 is fixedly connected to the inner side of the rod head 51, a long rod 53 is rotatably connected to the outer side of the pin 52, a round baffle 54 is fixedly connected to the long rod 53, and a spring 55 is fixedly connected to the outer side of the round baffle 54. The detection assembly 6 includes a horizontal plate 61, a round hole 62 is opened on the inner side of the horizontal plate 61, a sealing sleeve 63 is installed on the inner side of the round hole 62, a dustproof shell 64 is fixedly connected to the lower end of the horizontal plate 61, a circuit board 65 is fixedly connected to the inner side of the dustproof shell 64, a contact 66 is provided on one side of the circuit board 65, an electrical box 67 is fixedly connected to one side of the dustproof shell 64, and a surface mount LED 68 is provided on the inner side of the electrical box 67.

[0026] As a further implementation of this solution, the bottom surface of the detection component 6 and the bottom surface of the support frame 1 are on the same horizontal plane. The projection of the detection component 6 in the vertical direction is a rectangle, and the included angle between the connecting rod component 5 and the detection component 6 is 90°. This design is conducive to the stable placement of the components and improves the stability of the device.

[0027] As a further implementation of this solution, a slotted box 41 is bonded to one side of the film 45, the inner side of the mounting groove 42 is attached to the outer side of the film 45, and several airbags 46 are provided. The airbags 46 are evenly and equidistantly distributed on the inner side of the film 45. This design is more reasonable and conducive to the mutual fixation between components.

[0028] As a further implementation of this solution, one side of the film 45 is attached to the side of the perforated baffle 47, and several through holes 49 are provided. The positions of the through holes 49 correspond one-to-one with the positions of the airbag 46. The shape of the groove 48 between the baffles is arc-shaped. This design improves the wedge fit between the components and makes the fit between the components more precise.

[0029] As a further implementation of this scheme, the included angle between pin 52 and rod head 51 is 90°, the included angle between pin 52 and long rod 53 is 90°, the central axis of long rod 53 and the central axis of circular baffle 54 are on the same straight line, and the circular baffle 54 and spring 55 are on the same axis. This design is conducive to the transmission of force between components and improves the operating efficiency of the device.

[0030] As a further implementation of this solution, a long rod 53 is slidably connected to the inner side of the sealing sleeve 63. One end of the sealing sleeve 63 is attached to the circular baffle 54. Several sealing sleeves 63 are provided. The sealing sleeves 63 are evenly and equidistantly distributed in a rectangular array on the inner side of the horizontal plate 61. The number of circular holes 62 corresponds to the number of sealing sleeves 63. This design can reasonably plan the layout and avoid mutual obstruction between the components.

[0031] As a further implementation of this solution, a circuit board 65 is fixedly connected to the lower end of the spring 55, and the position of the contact 66 corresponds one-to-one with the position of the long rod 53. The circuit board 65 is electrically connected to the electrical box 67 through wires. This design enables the device to accurately receive the corresponding electrical signal, which is beneficial to the realization of the device's effect.

[0032] Workflow: During operation, the support frame 1 and roller 2 are lifted from the zinc pot equipment using hoisting tools and positioned according to the location of the cleaning component 4, ensuring the anti-corrosion layer 3 is directly above the cleaning component 4. Air is injected into the grooved box 41 through the air nozzle 44, causing the airbag 46 to inflate. At this time, the anti-corrosion layer 3 exerts pressure on the airbag 46. When the anti-corrosion layer 3 compresses the airbag 46, the airbag 46 deforms, simultaneously compressing the inner rod head 51, causing the rod head 51 to move. When the rod head 51 moves, it drives the long rod 53 to move via the pin 52, causing the long rod 53 to slide inside the sealing sleeve 63. When the long rod 53 moves, it drives the circular baffle 54 to move, and the movement of the circular baffle 54 compresses the spring 55, causing the spring 55 to... When the long rod 53 moves a certain distance, one end of the long rod 53 will contact the contact 66 on the circuit board 65. At this time, the circuit board 65 will transmit an electrical signal to the electrical box 67 through the wire. The electrical box 67 will control the corresponding surface-mount LED 68 to light up according to the received electrical signal. When the anti-corrosion layer 3 is rotated, the airbag 46 will clean the surface of the anti-corrosion layer 3. If the surface of the anti-corrosion layer 3 is damaged, the deformation caused by the compression of the airbag 46 at the corresponding position will not be enough to push the inner rod head 51 to move a certain distance. As a result, one end of the long rod 53 will not contact the contact 66 on the circuit board 65. The electrical box 67 will not receive the corresponding electrical signal and will not control the corresponding surface-mount LED 68 to light up. This allows for a quick determination of whether the anti-corrosion layer 3 is damaged.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
