Problems solved by technology
In order to restore the steel structure modular unit to the horizontal position after lifting, the method of adjusting the length of the sling is generally used in engineering, but this method will make the internal force distribution of the sling uneven, which will not only increase the extra calculation amount, but also cause increase the probability of accidents

The invention discloses a lifting device for a steel structure modular unit, and belongs to the technical field of structure lifting engineering. The lifting device comprises two parallel cross beams; parallel longitudinal beams are connected between the cross beams; the longitudinal beams are perpendicular to the cross beams; the cross beams and the longitudinal beams form symmetric lifting skeletons; two first adjusting rods parallel to the longitudinal beams are arranged between the cross beams, and are positioned at two ends of the length directions of the cross beams; support plates are arranged at two ends of the length directions of the cross beams; second adjusting rods parallel to the cross beams are arranged between two support plates on the same one side; the first adjusting rods and the second adjusting rods are both symmetrically arranged corresponding to the lifting skeletons, and are both provided with adjusting blocks; the adjusting blocks can move along the first adjusting rods or the second adjusting rods; four upper lifting lugs are symmetrically arranged at the tops of the lifting skeletons; and four lower lifting lugs are symmetrically arranged at the bottoms of the lifting skeletons. The lifting device is simple in structure, and can effectively solve the eccentric lifting problem of the steel structure modular unit when the gravity center is not in the geometric center.
Description
technical field [0001] The invention belongs to the technical field of structure hoisting engineering, in particular to a hoisting device for steel structure modular units. Background technique [0002] During the hoisting process of the steel structure modular unit, due to the requirements of the installation process, it is usually necessary to make the steel structure modular unit in a horizontal position in space after hoisting, so as to prevent the steel structure modular unit from tilting in the air and surrounding the hook when hoisting Rotation, etc., and the hook tension and the gravity of the steel structure modular unit also need to meet the two-force balance condition. For a geometrically regular steel structure modular unit, its center of gravity coincides with the center of symmetry, so arranging equal-length slings at the symmetrical center can make the steel structure modular unit in a horizontal position after hoisting. For steel structure modular units whos...
