Description

Technical Field

[0001] This utility model belongs to the field of aluminum-zinc plating pot equipment, specifically relating to a traveling device for an aluminum-zinc plating pot roller scraper. Background Technology

[0002] In aluminized zinc strip production lines, scrapers are installed on the zinc plating rollers (mainly including immersion rollers and stabilizing rollers). Their function is primarily to remove excess molten zinc and impurities from the roller surface, ensuring a uniform zinc plating layer, preventing excessively thick plating, and preventing impurities from transferring to the strip surface with the rollers and affecting plating quality. In existing technology, the scrapers on zinc plating rollers typically rely on a motor-driven screw and copper nut, moving via a cable chain to achieve the purpose of reciprocating scraping of molten zinc from the roller surface.

[0003] However, in the actual production environment of aluminized zinc strip steel, the copper nut and the lead screw rub against each other for a long time, causing the copper nut threads to wear gradually. Other problems, such as hard particles and high temperature affecting material properties, can also cause the traveling device of the boiler roller scraper to fail. Once the copper nut wears out, the lead screw mechanism cannot be replaced online. The boiler roller scraper will stay on a certain part of the surface of the aluminized zinc boiler roller, and zinc liquid will accumulate, which will directly lead to the problem of production stoppage. The machine will have to be stopped to replace the lead screw mechanism, which will greatly reduce the production efficiency of the aluminized zinc line.

[0004] Therefore, the applicant urgently needs to find technical solutions to address the above-mentioned technical problems. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a traveling device for an aluminum-zinc coated pot roller scraper. The scraper is driven by a traveling cylinder driven by a hydraulic station, so that the traveling cylinder drives the scraper to reciprocate on the surface of the aluminum-zinc coated pot roller, thereby realizing the traveling drive of the scraper.

[0006] The technical solution adopted in this utility model is as follows:

[0009] Preferably, the back of the aluminum-zinc coated pot roller scraper has a pre-drilled cylindrical pin hole, and the hydraulic cylinder connector is fixedly installed and connected to the cylindrical pin hole through the cylindrical pin.

[0010] Preferably, the piston rod is made of stainless steel tube, and a limiting angle iron is fixedly welded onto the stainless steel tube; at the same time, the traveling cylinder is provided with a first limit switch and a second limit switch distributed at left and right intervals, and the distance between the first limit switch and the second limit switch corresponds to the limiting stroke of the aluminum-zinc coated pot roller scraper traveling in a single direction on the surface of the aluminum-zinc coated pot roller; the first limit switch and the second limit switch are both inductively connected to the limiting angle iron.
