In addition, the jacking and positioning device has a high level of automation and is not prone to human operation errors. When assembling the flashing plate, the welding installation accuracy is high, which can avoid the poor matching problem between the flashing plate and the 120 valve, and improve the safety and durability of the overall structure. At the same time, the jacking and positioning device does not need to rely on manual operation, simplifies the tedious collaboration process, improves the assembly efficiency, and thus improves the production efficiency of the overall structure, reduces safety hazards, avoids workers from being easily fatigued in a high-intensity working environment, and thus reduces the risk of accidents.
