Abstract

The invention relates to the technical field of hoisting equipment, in particular to a horizontal deviation rectifying component and method for a hoisting turnover beam of large tank equipment. According to the invention, under the dead weight effect of the trapezoid block of the overturning pin shaft, the trapezoid block automatically rotates to enable the trapezoid block to fall into the limit groove of the auxiliary support, the inclined plane of the trapezoid block contacts with the inclined plane of the limit groove, and the deviation is corrected by the load down pressure and the inclined plane, so that the distance error generated between the main hinge supporting point and the auxiliary hinge supporting point due to the positioning marking error, the placing operation error and the integral deformation of the overturning beam is eliminated, and the horizontal direction eccentric correction function of the overturning beam is realized.
