【摘要】：QLY50H混合动力全液压轮胎起重机是用于港口搬运中的一种吊装设备，主要应用在港口、火车货场、汽车或专用平板货物车等装卸。QLY50H轮胎起重机既能保证吊装工作高效可靠又能实现电驱动工况无污染气体排放、低噪音、低能耗的目的。大吨位混合动力全液压轮胎起重机是一个大胆创新，目前国内外还没有先例，将填补国内外在该领域的空白。本文在提出QLY50H轮胎起重机的总体方案和主要零部件的结构设计之前，大量调研了国内以及国外工程起重机的实际应用情况和阅读了大量关于工程起重机的国内和国外的书籍、论文以及网上信息等相关文献。之后进行了QLY50H轮胎起重机的运动分析和动力分析，，并引入CAD/CAE技术，对关键支撑件（转台和车架）进行了Pro/E三维建模和装配，利用有限元软件Ansys14.0对主要支撑件（转台和车架）进行了有限元分析，计算结果证明了转台和车架设计的合理性和可靠性。不必采用较大的安全系数，从而使整个机器质量轻量化，为产品优化设计提出了理论依据。本课题设计的轮胎起重机具有整机外形尺寸小、转弯半径小、便于起重机在现场移动、该起重机支腿的横向跨距与纵向跨距相同，有利于起重机全周范围起重能力相同，在某一位置起吊后上车向任何方向旋转均不会发生翻车事故，增加了工作的安全性。该起重机性能高、价格低于国外同类产品，打破了国外产品垄断市场的局面。
[Abstract]:QLY50H hybrid fully hydraulic tyre crane is a kind of hoisting equipment used in port handling. It is mainly used in port and freight yard. QLY50H tire crane can not only guarantee the high efficiency and reliability of hoisting, but also realize the non-pollution gas emission and low noise in the electric driving condition. Large tonnage hybrid full hydraulic tyre crane is a bold innovation, there is no precedent at home and abroad at present, it will fill in the blank in this field at home and abroad. Before putting forward the general scheme of QLY50H tire crane and the structural design of main parts, this paper investigates the practical application of engineering crane both at home and abroad, and reads a lot of books about engineering crane both at home and abroad. After that, the motion analysis and dynamic analysis of QLY50H tire crane are carried out, and CAD/CAE technology is introduced to model and assemble the key support (turntable and frame) by Pro/E. The finite element analysis of main supports (turntable and frame) is carried out by using finite element software Ansys14.0. The results show that the design of turntable and frame is reasonable and reliable. Thus, the whole machine quality is lightweight and the theoretical basis for product optimization design is put forward. The tire crane designed in this paper has the advantages of small shape size and small turning radius, which is convenient for the crane to move on the spot. The transverse span of the leg of the crane is the same as the longitudinal span, and the lifting capacity of the crane is the same in the whole circumference range. After lifting in a certain position, there will be no accident of overturning and turning in any direction after lifting in a certain position, which increases the safety of work. The crane has high performance and lower price than the similar products from abroad, thus breaking the situation of monopoly market of foreign products.
