The invention discloses an automatic assembly alignment lifting appliance for a rectangular steel slab and a lifting method. The lifting appliance comprises a cross beam, wherein a lifting lug is arranged at the upper part of the cross beam, and a hydraulic clamping mechanism and a right-angle clamp are arranged at the two ends of the cross beam respectively; and a hydraulic jack is arranged on the hydraulic clamping mechanism and is in contact connection with the right-angle clamp. The automatic assembly alignment lifting appliance has the beneficial effects that firstly, the height of a sealing welding steel slab is increased, so that the weight of the weldable steel slab is increased; secondly, in a conventional mode, the alignment is manually carried out on a lifting vehicle by many people, the adjustment is carried out for multiple times, and after the lifting appliance is used, the automatic alignment can be realized after the alignment is carried out only by two persons; and finally, the production efficiency is improved, and the lifting appliance is safer.
本发明公开了一种矩形钢板坯自动组坯对正吊具及吊装方法,该吊具包括有横梁,在所述横梁的上部设置有吊耳、并在其两端分别设置有液压加持机构、直角钳,所述液压加持机构上设置有液压顶并与所述直角钳接触连接。本发明的有益效果在于:1.提高封焊钢坯高度,从而增大了可焊钢坯的重量。2、以往的方式需人工在升降车上,多人手推找正,需多次调整方可,使用吊具后,只需两人稍微调整,即可自动找正,3、提高了生产效率并更加安全。
