【摘要】：叉车作为减轻劳动者强度的主要工具之一,因其操纵灵活简单、适用面广而被普遍应用于物流运输搬运工作中。如何提高叉车的操纵舒适性,降低噪音、振动,达到更安全可靠、降低劳动强度的目的,是国产叉车需要解决的重要课题之一。对内燃平衡重式叉车,本文所研究的内容具有一定的通用性,对提高叉车的安全可靠性、搬运效率；降低劳动强度、减少排气污染及节能具有较大的实际意义。本文从整体上以宝鸡合力叉车厂的4.5吨新型环保叉车的总体设计为依据,讲述了叉车的总体方案设计、总体计算；动力系统匹配计算、叉车的牵引性能等；主要配套件选择工作的工作思路,为工业车辆机械的总体设计提供一个样板。从转向桥、负载感应优先转向阀入手,阐述了转向系统的结构原理,分析了转向桥的受力,计算了系统的强度及转向性能。介绍了系统的组成及各部件的结构；结合系统原理图分析了系统的原理,通过系统压力、流量计算,阐述了液压系统负荷感应优先转向原理,实现高效节能的设计效果。分析工作装置的受力情况,计算了主滚轮的强度、链条的安全系数,介绍了工作装置的降低噪音、减小振动措施,为驾驶员提供了较好的工作环境。该产品经试制及性能检测合格,能够满足国内、国际市场的需求,符合出口发达国家的基本条件；有效的解决了发达国家对于我国工业车辆的技术壁垒问题；避免因技术原因造成对其自身产品的保护。该产品的顺利设计研制成功,为企业进一步发展奠定了一定的基础,也为国内叉车行业的健康发展做出了应有的贡献。
[Abstract]:Forklift truck, as one of the main tools to lighten the intensity of laborers, is widely used in logistics transportation because of its flexible and simple operation and wide application. How to improve the handling comfort of forklift truck, reduce noise and vibration, achieve more safety and reliability, and reduce labor intensity, is one of the important issues that need to be solved by domestic forklift truck. For the internal combustion balance heavy forklift, the content of this paper has certain generality, which is of great practical significance to improve the safety and reliability of the forklift, to carry efficiency, to reduce the labor intensity, to reduce the exhaust pollution and to save energy. Based on the overall design of 4.5-ton new-type environmental protection forklift truck in Baoji Heping forklift Plant, this paper describes the overall scheme design, overall calculation, power system matching calculation, traction performance of forklift truck, etc. The main assembly selection work idea provides a model for the overall design of industrial vehicle machinery. Starting with the steering bridge and the load induction priority steering valve, the structure principle of the steering system is expounded, the force acting on the steering bridge is analyzed, and the strength and steering performance of the system are calculated. This paper introduces the composition of the system and the structure of each component, analyzes the principle of the system by combining with the system schematic diagram, expounds the principle of load induction priority steering of hydraulic system through the calculation of system pressure and flow rate, and realizes the design effect of high efficiency and energy saving. The strength of the main roller and the safety factor of the chain are calculated, and the noise reduction and vibration reduction measures of the working device are introduced, which provides a good working environment for the driver. The product can meet the needs of domestic and international markets and meet the basic conditions of developed countries, effectively solve the technical barriers of developed countries to China's industrial vehicles. Avoid the protection of its own products due to technical reasons. The successful design and development of the product has laid a certain foundation for the further development of the enterprise, and has also made due contribution to the healthy development of the forklift truck industry in China.
