Gravity center adjusting type lifting frame

Abstract

The invention relates to a gravity center adjusting type lifting frame. The gravity center adjusting type lifting frame comprises a bottom frame, a moving assembly and a traction piece. A lifting hookfor lifting goods is arranged on the bottom frame. The moving assembly is movably arranged on the bottom frame. One end of the traction piece is connected with the moving assembly and the other end of the traction piece is used for connecting a crane. In the gravity center adjusting type lifting frame, the lifting hook of the bottom frame lifts goods (such as a caisson), the traction piece is connected to the crane, and when the gravity center of the goods and the lifting point of the crane are not in the vertical direction, the moving assembly moves on the bottom frame to enable the liftingpoint of the lifting machine to be positioned over the gravity center of the goods, so that the unbalanced lifting phenomenon caused by deviation of the gravity center of the lifted goods and the lifting point is avoided, the lifting stability is greatly improved and the safety and the working efficiency are high.

Description

technical field [0001] The invention relates to a hanger, in particular to a center-of-gravity adjustable hanger. Background technique [0002] In the process of port loading and unloading, large-scale cargo is often hoisted, generally using direct hoisting techniques such as rings + shackles, but for some special cargo that can only bear vertical force, in order to ensure the structural safety of the cargo during hoisting , it is necessary to use some auxiliary hangers for lifting, as the intermediate structure between the lifting point and the cargo, and play the role of changing the force direction of the sling. For example, in the lifting of the caisson, in order to ensure that the caisson wall is not damaged during the lifting, it is necessary to use a lifting hanger to change the force direction of the caisson wall through the lifting hanger, so as to ensure that the caisson wall is not subject to lateral pressure. Traditional lifting hangers can be divided into singl...

AI Technical Summary

Problems solved by technology

However, in the process of hoisting goods with different sizes and inconsistent centers of gravity, the traditional hoisting hanger is prone to unstable hoisting, which leads to the easy swing of the hoisted goods, which increases the force on the hanger and causes dangerous accidents, so the safety is relatively low. low, low work efficiency
