Application of Electric Pulse Permanent Magnet Lifter to Steel Pipe Automatic Lifting Operation

摘要: 針對永磁、電磁起重器在鋼管吊裝過程中存在的問題，提出了采用電脈沖永磁起重器的吊裝方式；討論了電脈沖永磁起重器在鋼管自動化吊裝應(yīng)用中的布置形式以及影響拉脫力形成的因素，如鋼管壁厚、氣隙及接觸面等。電脈沖永磁起重器具有永磁節(jié)能安全和電磁極性轉(zhuǎn)換方便的優(yōu)點(diǎn)，實(shí)現(xiàn)了鋼管磁力起重器吊裝自動化。

Abstract: Addressing the problems related to the permanent magnet and electromagnet lifters as encountered with in the process of steel pipe lifting, the electric pulse permanent magnet lifter is proposed.Discussed here in the article are the arrangement type of the said lifer for steel pipe automatic lifting operation, and the key factors affecting formation of pull-out force, such as steel pipe wall thickness, air gap and contact surface, etc.The electric pulse permanent magnet lifter is in possession of energy-saving and operation safety due to permanent magnetism, and convenient conversion of electric magnet polarity, which has brought about the automation of the steel pipe lifting operation with the magnetic lifter.
