After the position is adjusted, the first adjusting bolt 71 is tightened to fix the first fixing seat 3 on the bracket assembly 100. By setting the first waist-shaped hole 31 and the first adjusting bolt 71, the position of the first fixing seat 3 relative to the bracket assembly 100 can be fine-tuned, which is conducive to eliminating the overall cumulative error when the furnace upper cover lifting device is installed. In this embodiment, the first adjusting bolt 71 is connected to both the first bracket 101 and the second bracket 102, and correspondingly, two first waist-shaped holes 31 are set on the first fixing seat 3, and the number of the first waist-shaped holes 31 and the number of the first adjusting bolts 71 are set one by one. One side of the first fixing seat 3 is connected to the first bracket 101, and the other side of the first fixing seat 3 is connected to the second bracket 102.
