Description

Technical Field

[0001] This utility model relates to the field of pipeline rust removal technology, and in particular to an automatic laser rust removal device for pipelines. Background Technology

[0002] In modern industrial production and infrastructure construction, pipelines serve as vital carriers for fluid transportation, making internal and external corrosion protection and maintenance crucial. Over time, pipeline surfaces are highly susceptible to corrosion, which not only affects their appearance but also severely impacts transportation efficiency, reduces pipeline strength, and can even lead to corrosion leaks, causing safety accidents and environmental pollution. Therefore, regular rust removal treatment of pipelines is essential to ensure their normal operation and extend their service life.

[0003] Currently, commonly used pipeline rust removal technologies in the industry mainly include mechanical and physical methods such as shot blasting and sandblasting. While these traditional methods can achieve rust removal to a certain extent, they generally have some inherent problems. For example, shot blasting and sandblasting equipment often have complex structures with many vulnerable parts, resulting in high maintenance costs. Furthermore, abrasives are consumables that require continuous replenishment, further increasing operating costs. In addition, these mechanical rust removal methods generate a large amount of dust and noise during operation, causing significant pollution to the health of operators and the surrounding environment, affecting the quality of the working environment, and potentially posing certain safety hazards, such as the possibility that high-speed abrasive jets could penetrate protective equipment.

[0004] In recent years, laser rust removal has gradually gained attention due to its non-contact, high-precision, and environmentally friendly characteristics, and is especially suitable for localized precision rust removal and automated operations. However, most existing laser rust removal equipment is manually controlled or has a fixed structure, lacking the flexible support and tracking adjustment capabilities adapted to cylindrical pipes. This makes it difficult to guarantee rust removal efficiency and consistency, and its dust control capabilities are weak, posing a risk of secondary pollution.
