[Abstract]:The rapid development and strong vitality of container transportation has led to a transportation revolution, which puts forward new higher requirements for port handling equipment. In order to improve the working efficiency of loading and unloading containers and reduce energy consumption, new ideas are emerging one after another. Among them, the weight balance system design of boom crane has an important impact on the production. The innovation research of self-weight balance system may reduce the weight of the whole machine and reduce the driving power of the luffing mechanism. And to make up for the shortcomings of the previous self-weight balance system, improve the working performance of the crane. In this paper, the working principle of a new type of deadweight balance system for various jib cranes is theoretically analyzed, and its mathematical model is established by selecting suitable types, and its working characteristics are calculated and analyzed by using the MATLAB genetic algorithm toolbox. Through the comparison and analysis of the characteristic parameters, such as the unbalance force of self-weight, it is concluded that the sliding path deadweight balancing system of the rocker balance beam is applicable and effective. On the basis of this, a set of software is developed to guide the actual engineering design of the gantry crane amplitude change system including the self-weight balance system. The specific work carried out in this paper and the research results obtained are as follows: 1) on the basis of collecting the types of deadweight balance system at home and abroad and clarifying the design methods and principles of gantry crane luffing system, this paper expounds the important influence of the weight balance system on the luffing mechanism and the whole crane performance. It lays a foundation for the innovation research of self-weight balance system. (2) taking the connecting rod counterweight balance system of the quayside container jib crane as the breakthrough point, the sliding block motion pair is introduced, and five new self-weight balancing systems are proposed by derivation. Through the analysis and comparison, the self-weight balance system with excellent performance is obtained, that is, the balance system of the balance beam and the balance system of the balance beam with the sliding path of the shaking frame. 3) for the above two self-weight balancing systems, a mathematical model which can correctly describe the influence of the main design parameters of the system on the self-weight balance characteristics is established. 4) the applicability of the optimization design method of the deadweight balance system is analyzed, and the genetic optimization algorithm is selected as the optimal design method in this paper, combined with the research and discussion of the research group. 5) by using MATLAB genetic algorithm toolbox, the optimization design of two new deadweight balancing systems is completed, and the applicability of the sliding track deadweight balance system of rocker balance beam is obtained. Based on VC software development platform, a computer aided design software is developed for sliding track deadweight balance system of rocker balance beam.
