【摘要】：在港口運(yùn)輸中,集裝箱運(yùn)輸散糧的發(fā)展趨勢越來越明顯,我國每年以散裝集裝箱方式運(yùn)輸散貨量巨大,但目前多以人工簡單操作(人工踩踏)的方式來攤平充實(shí)貨物,存在著勞動(dòng)強(qiáng)度大、工作效率低下、裝箱率不高且易發(fā)生危險(xiǎn)事故等問題。通過對(duì)散裝集裝箱方式攤平問題的分析,以節(jié)省人力物力和提高裝箱率為目標(biāo),本文研究設(shè)計(jì)了一種攤平充實(shí)系統(tǒng)。利用傘狀耙齒拔桿機(jī)構(gòu)和下落速度提供的動(dòng)力攤平集裝箱中的散裝貨物,以提高裝箱率。采用模塊化的設(shè)計(jì)方法根據(jù)實(shí)際工況的需求,對(duì)攤平充實(shí)系統(tǒng)的支撐回轉(zhuǎn)機(jī)構(gòu)模塊,執(zhí)行機(jī)構(gòu)模塊進(jìn)行了方案選取,結(jié)構(gòu)設(shè)計(jì)。確定了支撐回轉(zhuǎn)機(jī)構(gòu)模塊的結(jié)構(gòu)和類型;設(shè)計(jì)了幾種不同的執(zhí)行機(jī)構(gòu)方案,并進(jìn)行對(duì)比分析確定出最優(yōu)方案并進(jìn)行了方案的優(yōu)化。支撐回轉(zhuǎn)機(jī)構(gòu)的立柱的高度和懸臂的長度進(jìn)行尺寸計(jì)算;并對(duì)執(zhí)行機(jī)構(gòu)拔桿,上壓板,下壓板,導(dǎo)向柱根據(jù)集裝箱尺寸進(jìn)行了尺寸設(shè)計(jì),分析了撥爪的受力狀態(tài),對(duì)執(zhí)行機(jī)構(gòu)各部分的質(zhì)量進(jìn)行了計(jì)算。利用ABAQUS有限元分析軟件,模擬在實(shí)際工作環(huán)境下各撥桿的承重載荷,對(duì)執(zhí)行機(jī)構(gòu)進(jìn)行了強(qiáng)度校核,得到了撥爪在工作時(shí)的應(yīng)力圖和變形圖。通過對(duì)關(guān)鍵機(jī)構(gòu)的有限元仿真結(jié)果進(jìn)行分析,得出各關(guān)鍵部件發(fā)生變形的原因。同時(shí)根據(jù)實(shí)際工況搭建了實(shí)體模型,模擬了執(zhí)行機(jī)構(gòu)的工作過程。對(duì)大豆攤平充實(shí)系統(tǒng)電氣控制模塊進(jìn)行了設(shè)計(jì)。在旋轉(zhuǎn)運(yùn)動(dòng)模塊和水平運(yùn)動(dòng)模塊對(duì)其原理和組成進(jìn)行了概述,并對(duì)電動(dòng)機(jī)進(jìn)行了選擇;設(shè)計(jì)了一種智能提拉裝置,完成了該裝置的控制設(shè)計(jì)和電氣元件選取,同時(shí)完成了各電氣元件控制電路的設(shè)計(jì)和程序的編寫,完成了電氣控制系統(tǒng)的設(shè)計(jì)。
[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.
