Eccentric structure hydraulic lifting process balance control device and control method

Abstract

The invention provides an eccentric structure hydraulic lifting process balance control device and a control method, the eccentric structure hydraulic lifting process balance control device comprises a lifting joist, the lifting joist at least comprises two groups of lower anchor points, and the lower anchor points are of an asymmetric structure relative to the center line of the lifting joist; the reinforcing assemblies are arranged on the upper end face of the lifting joist, and a lifted eccentric structure is arranged between the reinforcing assemblies; and the lifting driving device is connected to the two groups of lower anchor points and drives the lifting joist to ascend. The eccentric structure can be lifted, eccentricity of the eccentric structure in the lifting process can be reduced, overturning of the eccentric structure in the arc direction and torsion of the end of the eccentric structure are avoided, safety of the eccentric structure in the lifting process is effectively guaranteed, and the high-altitude butt joint precision and efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of eccentric structure lifting, in particular, to an eccentric structure hydraulic lifting process balance control device and a control method. Background technique [0002] With the construction of more and more large-span space special-shaped buildings, hydraulic lifting construction technology is also widely used in steel structure buildings. In the previous lifting construction process, eccentricity and unbalanced weight distribution of the lifted structure were often avoided as much as possible. In order to ensure the structural balance of the lifting process, but in the process of lifting the large-span eccentric structure, the center of gravity deviates from the effective lifting area formed by the connection line between the two ports of the main box girder in the arc section, and there is an overturning area in the arc direction. At the same time, because the structure is in an eccentric state, when...

Problems solved by technology

[0002] With the construction of more and more long-span special-shaped buildings, hydraulic lifting construction technology is also widely used in steel structure buildings. In the past lifting construction process, it is often possible to avoid eccentricity and uneven weight distribution of the lifted structure etc., so as to ensure the structural balance in the lifting process. However, during the lifting construction process of the large-span eccentric structure, the center of gravity deviates from the effective lifting area formed by the connection line between the two ports of the main box girder in the arc section, and there is a possibility of overturning in the arc direction. At the same time, because the structure is in an eccentric state, when the two ends are constrained, there is a torsion tendency at the end of the structure

Therefore, the lifting process of the eccentric structure is difficult, and it is easy to cause the lifted structure to overturn and the end torsion
