The invention relates to a flexible leg connecting hinge. The flexible leg connecting hinge comprises an upper support connected with a girder support flange by a bolt and a lower support connected with a landing leg flange by a bolt; the flexible leg connecting hinge is characterized in that a hinging shaft is arranged between the upper support and the lower support, two ends of the hinging shaft are fixed with shaft locking plates, and a shaft sleeve is arranged between the hinging shaft and the upper support and the lower support; oil cups are arranged at two ends of the hinging shaft, grooves are formed at the contact positions of the two ends of the hinging shaft and the shaft sleeve, and the grooves are communicated with the oil cups; and the shaft locking plate is fixed with a gasket by a bolt. The flexible leg connecting hinge can effectively solve the problem of rail gnawing of the cart, caused by structure deformation of a portal crane with the span more than 35m due to temperature difference.
