Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment technology for submerged arc furnaces, and specifically to a multi-functional robotic arm for the front of a submerged arc furnace. Background Technology

[0002] Submerged arc furnaces are essential pieces of equipment in the modern metallurgical industry. During operation, they require periodic opening for tasks such as charging, feeding, pushing, and tamping. Traditionally, these operations are done manually, with three or more workers holding the corresponding tools and positioned near the furnace to insert them into the furnace. However, due to the high temperature at the furnace entrance, this method can be harmful to the workers. Furthermore, as the capacity of submerged arc furnaces increases, so does the workload, requiring greater effort and longer working hours. Prolonged high-intensity work in such a high-temperature environment can cause varying degrees of physical strain on the workers. Summary of the Invention

The mounting head is equipped with corresponding operating tools and is located at the front end of the telescopic assembly. The telescopic assembly moves the mounting head to extend or retract, the swing power cylinder moves the mounting head to swing up and down, the lifting assembly moves the mounting head to lift vertically, the planar rotary disk moves the mounting head to rotate horizontally, and the horizontal movement assembly moves the mounting head horizontally.
