【摘要】：翻车机是港口卸煤生产线上的重要设备，而定位车在翻车机系统中又起着重要的作用，对港口的卸煤生产产生重要影响。因此该文章对卸煤生产线上的定位车进行分析和研究，解决其在运行过程中出现的实际问题，具有重要的实际应用价值。黄骅港一期翻车机系统是由德国ThyssenKrupp公司于2001-2003年设计制造的。由于长期高负荷运转导致设备出现裂缝，以及设备更新换代方面的配套等相关问题，严重影响了翻车机的正常运转和生产任务的顺利完成，因此要对其进行深入的分析并加以改进。论文在对定位车仰俯机构的工作原理进行分析的基础上，对原有仰俯系统进行了运动学分析；并通过机构学知识设计了新型的运动机构，对新机构进行了运动学分析，为其后期改造提供了依据。针对原大臂的结构和载荷，，进行了静力学分析，找出大臂结构的薄弱点；针对新设计的大臂进行了静力学分析，验证新的大臂结构上的安全可靠性。根据定位车液压系统的工作原理，对液压系统进行分析研究，利用软件对其进行了仿真计算。找出液压系统存在的弊端，提出解决方案。
[Abstract]:The dumper is an important equipment in the port coal unloading production line, and the positioning car plays an important role in the dumper system, which has an important impact on the coal unloading production of the port.Therefore, this paper analyzes and studies the positioning vehicle in the coal unloading production line, solves the practical problems in the process of operation, and has important practical application value.Huanghua Port Phase I dump system was designed and manufactured by German ThyssenKrupp Company in 2001-2003.As a result of the long term high load operation resulting in equipment cracks, as well as equipment replacement and other related problems, seriously affected the normal operation of the turning over machine and the smooth completion of production tasks.Therefore, it should be deeply analyzed and improved.Based on the analysis of the working principle of the pitching mechanism of the positioning vehicle, the kinematics analysis of the original pitching system is carried out, and a new type of kinematic mechanism is designed through the knowledge of mechanism, and the kinematics analysis of the new mechanism is carried out.It provides the basis for its later transformation.According to the structure and load of the original arm, the statics analysis is carried out to find out the weakness of the structure of the arm, and the statics analysis of the new designed arm is carried out to verify the safety and reliability of the new structure.According to the working principle of the hydraulic system of the positioning vehicle, the hydraulic system is analyzed and studied, and the software is used to simulate the hydraulic system.Find out the malpractice of hydraulic system and put forward the solution.
