Modular Energy-saving Design Of Bridge Crane Trolley For Green Service

Hoisting machinery plays an important role in various industrial sectors of the country,and is an indispensable key machinery and equipment for all kinds of production activities.Its design and manufacturing level reflects the country’s modern industrial development level from the side,and is a crucial indicator of a nation’s overall strength.As the core functional part of the crane,the design of the trolley directly affects the overall performance of the crane,and it has higher research value.At present,the traditional design method of crane has gradually failed to keep up with the new changes in the international industrial pattern,the old conservative design concept has been divorced from the current national energy saving,high efficiency,green and sustainable development purposes.Therefore,aiming at the problems of low green degree,poor design efficiency and high service cost of crane trolley,this paper proposes a series of green design methods to minimize the influence of the crane trolley on the environment throughout its life cycle.To solve these problems,the following research work will be carried out:1)Taking the crane trolley as the research object,the traditional crane trolley transmission chain architecture is reoptimized to increase transmission effectiveness.Sort out the main design parameters and design methods of the core components of the mechanism,provide relevant verification criteria for each component,and reasonably analyze the mechanical model of the trolley bearing frame structure and the loads it bears,to determine the calculation method of each wheel pressure.2)Attempting to address the issues of low design efficiency,huge parameter margin,and high service cost in the design and manufacturing process of crane trolleys,a modular design method is proposed,which utilizes the highly integrated and serialized characteristics of crane trolleys to reasonably divide the functional modules of crane trolleys.In collaboration with advanced intelligent optimization algorithms,the crane trolley system is modular restructured with the goal of weight reduction and energy conservation,to achieve rapid parameter matching of the trolley system.3)Aiming at the difficulty in characterizing the energy consumption indicators of the crane trolley during its service life,a quantitative method for evaluating energy consumption is proposed.By analyzing the working cycle characteristics and service energy consumption characteristics of the crane trolley,the factors that affect and the methods how energy consumption is calculated are identified.According to the key factors such as the service process parameters of the crane trolley and the motor load rate,the service energy consumption of the trolley lifting mechanism and operating mechanism is evaluated respectively.Finally,in view of the impact of trolley wheel pressure on energy consumption,combined with intelligent optimization algorithms,the weight distribution of the crane trolley structure is re planned and analyzed to determine the optimal layout of the trolley.4)Aiming at the problems of poor efficiency,low versatility,and low flexibility in the traditional design mode of cranes,a unified integration of various design modules for crane trolleys is proposed using Visual Studio 2022 as the development environment,C # as the development language,and objectoriented programming ideas to build a complete visual design platform for crane trolleys.The design platform converts the basic theoretical calculation method into a visual interface calculation in the form of code in a post program.According to the initial design parameters in the user agreement,the crane trolley can be reasonably designed through optimization algorithms,providing the user with the best design scheme,and ultimately outputting the results in the form of a manual to achieve a flexible,efficient,and shared design mode.
