Description

Technical Field

[0001] This patent application belongs to the field of protective cover technology, and more specifically, relates to a protective cover for lamp source to prevent deviation. Background Technology

[0002] The edge alignment device for hot-rolled coils at Hebei Iron & Steel Chengde Steel is installed in front of the coiler, below the high-speed running coil. Through a signal receiver, it receives the light signal emitted by the alignment device lamp source below the coil to determine the position of the coil edge and then feeds back to the mandrel to adjust the position. However, during equipment maintenance, debris falling can cover or even damage the lamp source. At the same time, during production, falling iron oxide scale, moisture, and dust can also affect the lamp source and obstruct the signal, resulting in inaccurate coil position judgment. Therefore, the alignment device lamp source needs to be wiped every hour, which is a lot of work. Once damaged, replacement requires large lifting equipment, which is time-consuming and labor-intensive. Utility Model Content
