【摘要】：在港口运输中,集装箱运输散粮的发展趋势越来越明显,我国每年以散装集装箱方式运输散货量巨大,但目前多以人工简单操作(人工踩踏)的方式来摊平充实货物,存在着劳动强度大、工作效率低下、装箱率不高且易发生危险事故等问题。通过对散装集装箱方式摊平问题的分析,以节省人力物力和提高装箱率为目标,本文研究设计了一种摊平充实系统。利用伞状耙齿拔杆机构和下落速度提供的动力摊平集装箱中的散装货物,以提高装箱率。采用模块化的设计方法根据实际工况的需求,对摊平充实系统的支撑回转机构模块,执行机构模块进行了方案选取,结构设计。确定了支撑回转机构模块的结构和类型;设计了几种不同的执行机构方案,并进行对比分析确定出最优方案并进行了方案的优化。支撑回转机构的立柱的高度和悬臂的长度进行尺寸计算;并对执行机构拔杆,上压板,下压板,导向柱根据集装箱尺寸进行了尺寸设计,分析了拨爪的受力状态,对执行机构各部分的质量进行了计算。利用ABAQUS有限元分析软件,模拟在实际工作环境下各拨杆的承重载荷,对执行机构进行了强度校核,得到了拨爪在工作时的应力图和变形图。通过对关键机构的有限元仿真结果进行分析,得出各关键部件发生变形的原因。同时根据实际工况搭建了实体模型,模拟了执行机构的工作过程。对大豆摊平充实系统电气控制模块进行了设计。在旋转运动模块和水平运动模块对其原理和组成进行了概述,并对电动机进行了选择;设计了一种智能提拉装置,完成了该装置的控制设计和电气元件选取,同时完成了各电气元件控制电路的设计和程序的编写,完成了电气控制系统的设计。
[Abstract]:In port transportation, the development trend of bulk grain transportation in container transportation is more and more obvious. In China, the bulk cargo is transported in bulk container mode every year. However, at present, most of the bulk goods are flattened out by manual simple operation (manual trampling). There are many problems, such as high labor intensity, low working efficiency, low packing rate and dangerous accidents. Based on the analysis of the problem of unevenness of bulk containers and aiming at saving manpower and material resources and increasing the packing rate, a kind of flattening and filling system is designed in this paper. In order to improve the packing rate, the utility model uses the umbrella rake pullout mechanism and the falling speed to balance the bulk cargo in the container. According to the requirements of actual working conditions, the modular design method is adopted to select the scheme and design the structure of the supporting rotary mechanism module and the actuator module of the flattening and enriching system. The structure and type of the supporting rotary mechanism module are determined, and several different executive mechanism schemes are designed, and the optimal scheme is determined by comparing and analyzing and optimizing the scheme. The height of the column supporting the rotary mechanism and the length of the cantilever are calculated, and the dimensions of the rod drawing, the upper pressure plate, the lower pressure plate and the guide column of the actuator are designed according to the size of the container, and the force state of the claw is analyzed. The quality of each part of the executive body is calculated. Using ABAQUS finite element analysis software, the load-bearing load of each lever in actual working environment is simulated, the strength of the actuator is checked, and the stress and deformation diagrams of the claw are obtained. By analyzing the finite element simulation results of the key mechanism, the causes of the deformation of the key components are obtained. At the same time, a solid model is built according to the actual working conditions, and the working process of the actuator is simulated. The electrical control module of soybean flattening system is designed. The principle and composition of the rotating motion module and the horizontal motion module are summarized, and the motor is selected, an intelligent lifting device is designed, the control design of the device and the selection of electrical components are completed. At the same time, the design and program of the control circuit of each electrical element are completed, and the design of the electric control system is completed.
