Description

Intelligent lifting equipment for transformer core Technical Field The invention relates to the technical field of hoisting. More particularly, the invention relates to intelligent hoisting equipment for a transformer core. Background In the prior art, when a transformer iron core is hoisted from a horizontal state to a vertical state, one ends of four equal-length binding bands are respectively fixed on four hanging rings which are rectangular in distribution and on the iron core, the other ends of the four equal-length binding bands are commonly connected to one hanging hook of a gantry crane, and meanwhile, two annular binding bands are sleeved on a base of the iron core and fixed on the other hanging hook of the gantry crane. Through the cooperation of the two lifting hooks, the iron core is firstly lifted horizontally, and then one lifting hook drives the annular binding belt to slowly descend, so that one end of the iron core base gradually moves downwards, and the iron core is turned to a vertical state. However, in the initial horizontal lifting stage, since the four lifting rings have a height difference in the vertical direction (the upper and lower two rows of lifting rings are not in the same horizontal plane), the upper ends of the four equal-length binding bands are fixed on the lifting hooks with the same height, so that the binding bands for connecting the lifting rings below are always in a tight state, and the binding bands for connecting the lifting rings above are in a loose state and cannot effectively participate in stress, thereby reducing the stability of the whole lifting process. Disclosure of Invention In order to overcome the defects that when the transformer iron core is horizontally hoisted in the prior art, the binding belt connected with the hanging ring below is always in a tightening state, and the binding belt connected with the hanging ring above is in a loosening state and cannot effectively participate in stress, so that the stability of the whole hoisting process is reduced, the invention provides intelligent hoisting equipment for the transformer iron core.
