【摘要】:隨著我國(guó)經(jīng)濟(jì)快速穩(wěn)定的發(fā)展,現(xiàn)代石油、化工、電力、冶金、市政建設(shè)和造船行業(yè)方面也得到了快速的發(fā)展,吊裝工程隨之越來(lái)越多,重達(dá)百噸及千噸的吊裝設(shè)備逐漸普及,并且吊裝設(shè)備的形狀也千變?nèi)f化,吊裝作業(yè)及現(xiàn)場(chǎng)環(huán)境也日趨復(fù)雜,致使吊裝方案的安全性、可靠性和高效性倍受關(guān)注。站位設(shè)計(jì)是吊裝方案的重要環(huán)節(jié)之一,起重機(jī)合理的站位不僅可以提高工作效率,而且能夠避免可能發(fā)生的危險(xiǎn),如碰撞危險(xiǎn)、超載現(xiàn)象等,因此站位設(shè)計(jì)在吊裝安全性方面具有舉足輕重的作用。 首先,對(duì)履帶起重機(jī)的結(jié)構(gòu)與機(jī)構(gòu)及其機(jī)構(gòu)的工作原理進(jìn)行了分析,然后對(duì)履帶起重機(jī)進(jìn)行塔類設(shè)備吊裝的吊裝方式進(jìn)行了研究,得出了在吊裝過(guò)程中可能存在的危險(xiǎn)因素,最后對(duì)常見的站位優(yōu)化方式進(jìn)行了分析和研究。 其次,在研究了相關(guān)站位優(yōu)化方法的基礎(chǔ)上,針對(duì)復(fù)雜的吊裝作業(yè)環(huán)境,給出了單機(jī)單任務(wù)的站位優(yōu)化方法。該方法以起重機(jī)工作包絡(luò)軌跡思想為基礎(chǔ),建立起重機(jī)的可行站位區(qū)域,利用網(wǎng)格離散該區(qū)域,在每個(gè)網(wǎng)個(gè)點(diǎn)進(jìn)行吊裝仿真及三維碰撞檢測(cè),剔除發(fā)生碰撞的點(diǎn),最后基于安全性考慮,建立加權(quán)和優(yōu)化目標(biāo),采用枚舉法遍歷可行站位點(diǎn),最終求得起重機(jī)的最佳站位點(diǎn)。 最后,考慮現(xiàn)代吊裝作業(yè)的特點(diǎn),雙機(jī)協(xié)同吊裝已經(jīng)越來(lái)越普遍,因此本文給出了兩臺(tái)起重機(jī)協(xié)同作業(yè)下的站位優(yōu)化方法。該方法考慮吊裝設(shè)備、主起重機(jī)和溜尾起重機(jī)三者的站位。首先建立合理的搜索區(qū)域,利用二分法搜索該區(qū)域,以吊裝設(shè)備的位置確定兩臺(tái)起重機(jī)的可行站位區(qū)域,離散該區(qū)域,在各離散點(diǎn)利用吊裝仿真和三維碰撞檢測(cè),排除發(fā)生碰撞的點(diǎn),基于安全性考慮,建立加權(quán)和優(yōu)化目標(biāo),采用枚舉法遍歷吊裝設(shè)備與兩臺(tái)起重機(jī)的可行站位點(diǎn),最終求得三者的最佳站位點(diǎn)。 本文在深入分析了解了履帶起重機(jī)的吊裝作業(yè)過(guò)程的基礎(chǔ)上,針對(duì)單臺(tái)和兩臺(tái)履帶起重機(jī)的站位優(yōu)化進(jìn)行了深入的研究,并將研究所得站位優(yōu)化方法嵌入到本課題組研制開發(fā)的三維吊裝仿真系統(tǒng)中,作為智能計(jì)算模塊的一部分,并借助三維吊裝系統(tǒng)軟件進(jìn)行了案例分析,分析結(jié)果檢驗(yàn)了方法的實(shí)用性與可行性,有效的提高了吊裝方案的制作效率,解放了吊裝方案工作人員的勞動(dòng)力。
[Abstract]:With the rapid and stable development of economy in our country, modern petroleum, chemical industry, electric power, metallurgy, municipal construction and shipbuilding industry have also got rapid development. Hoisting equipment weighing up to 100 tons and thousands of tons is becoming more and more popular, and the shape of lifting equipment is also changing, and the lifting operation and site environment are becoming more and more complex, resulting in the safety of hoisting scheme. The reliability and high efficiency are paid more attention to. The design of station is one of the most important parts of the hoisting scheme. The reasonable station of crane can not only improve the working efficiency, but also avoid the possible hazards, such as collision risk. Overloading phenomenon, so station design in hoisting safety has a pivotal role. Firstly, the structure and mechanism of crawler crane and its working principle are analyzed, and then the hoisting mode of tower equipment for crawler crane is studied. The possible risk factors in the hoisting process are obtained, and the common optimization methods are analyzed and studied. Secondly, on the basis of the research on the optimization method of the related stations, a single task optimization method is presented for the complex hoisting operation environment. The method is based on the idea of the crane working envelope trajectory. The feasible station area of the crane is established and the grid is used to discretize the area. The hoisting simulation and 3D collision detection are carried out at each net point, and the collision point is eliminated. Finally, the security considerations are considered. The weighted and optimal objectives are established, and the feasible station points are traversed by enumeration method, and finally the optimal station points of the crane are obtained. Finally, considering the characteristics of modern hoisting operation, the double-machine cooperative hoisting has become more and more common, so this paper gives the optimization method of the station position under the cooperative operation of two cranes, which considers the hoisting equipment. First of all, the reasonable search area is established, the region is searched by dichotomy, the feasible station area of the two cranes is determined by the location of hoisting equipment, and the region is dispersed. By using hoisting simulation and 3D collision detection in each discrete point, the collision point is excluded. Based on the safety considerations, the weighted and optimal objectives are established, and the feasible station points of hoisting equipment and two cranes are traversed by enumeration method. Finally, find out the best position of the three points. Based on the deep analysis and understanding of the lifting operation process of crawler crane, this paper makes a deep research on the optimization of the station of single and two crawler cranes. The optimization method of research station is embedded in the 3D hoisting simulation system developed by our team, as part of the intelligent calculation module, and the case analysis is carried out with the help of the software of 3D hoisting system. The results verify the practicability and feasibility of the method, improve the production efficiency of the hoisting scheme, and free the labor force of the workers of the hoisting scheme.
