Lifting carrying pole reinforcement method based on simulation modeling and lifting carrying pole

Abstract

The invention relates to a hoisting carrying pole reinforcement method based on simulation modeling and a hoisting carrying pole, and the method comprises the steps: building a finite element model, which mainly comprises the structure of the hoisting carrying pole determined according to engineering design, and drawing a three-dimensional solid model of the hoisting carrying pole; endowing the three-dimensional solid model with material attributes; carrying out unit grid division on the three-dimensional solid model of the hoisting shoulder pole; applying constraint and load to obtain a finite element model, and performing simulation calculation on the established finite element model to obtain stress of each part of the hoisting shoulder pole; the three-dimensional solid model of the hoisting carrying pole is modified, reinforcing ribs are arranged at the positions where the stress of the hoisting carrying pole is larger than a threshold value, and the steps are repeated till the stress of each position of the hoisting carrying pole meets the threshold value. The method has the advantages that the stress of each part of the hoisting carrying pole is comprehensively analyzed through a scientific simulation modeling method and a finite element calculation method, so that the parts with relatively large stress are checked, and then the parts are specifically reinforced through the reinforcing ribs, so that the structural strength of the hoisting carrying pole is improved.

Description

technical field [0001] The invention relates to the technical field of civil engineering equipment, in particular to a method for reinforcing a hoisting shoulder pole based on simulation modeling. Background technique [0002] At present, whether it is an above-ground project or an underground project, hoisting poles are generally used when hoisting large objects. In underground engineering, the construction of underground diaphragm walls generally adopts the process of making steel cages on the ground and hoisting them in place as a whole. As the depth of the foundation pit continues to deepen, the quality of the reinforcement cage itself becomes larger and larger, which increases the difficulty of the overall hoisting construction and highlights safety issues. In order to ensure the smooth lifting and safe construction of the steel cage, the lifting components are required to have sufficient strength and rigidity. The lifting components are mainly composed of shoulder pol...

Problems solved by technology

The existing hoisting poles are generally not analyzed for strength and stiffness in the design process, and the hoisting poles are prone to instability in the air after hoisting large heavy objects, and there are major safety hazards during use
