发布时间：2018-10-19 11:02
【摘要】：目前,国内研制的轮式拖拉机产品在农机具配套和工程变型应用技术方面有了大幅的提高,特别是前装载和后挖掘应用已基本趋于完善。但随着农业机械化的迅速发展和与其它领域的相互交叉,拖拉机的作业种类逐渐增多,交叉作业、复式作业等多种作业方式的大量采用,要求拖拉机所能发挥的功能也越来越多,其工程变型产品也趋于多样化。2011年国家部门《建设新农村机械装备需求分析》报告中对农田作业、饲料生产、新能源生产等领域对叉车衍生产品的需求做了分析,提出了农用物料产品的搬运需求。在此背景下,针对新生代工农业和新农村机械装备要求,研制一种适用于在农、牧、林业未经平整的地面或表层被破坏的场地上进行作业的叉装车就显得很有必要了,该叉装车不仅适用于物料的装卸、堆垛及搬运等,也可用于新农村建设、管道敷设、码头货场等工作环境中物料的装卸、搬运、转场等作业。本论文所做的主要工作包括:1、针对当前农、牧、林等行业对物料搬运车辆的需求提出研究课题,通过市场调研并探讨国内外相关产品的发展现状。2、根据具体作业要求和工作环境,拟采用四驱型拖拉机传动系,配套动力29.4kW。其次根据农、牧、林等行业对物料搬运车辆的要求,确定1.5吨拖拉机叉装车的基本设计参数:额定起重质量1500kg,最大起升高度3300mm,以保证在未经平整的地面或表层被破坏的场地上充分发挥整机四轮驱动和越野性能,满足作业要求。3、在确定1.5吨拖拉机叉装车基本参数的基础上,对其主要零部件进行选型及设计,包括四驱型拖拉机传动系、工业叉车工作装置、行走系轮胎选型等。4、利用Pro/E软件搭建了1.5吨拖拉机叉装车虚拟样机,并完成车架、护顶架、覆盖件等设计;通过内嵌于Pro/E软件的Mechanica技术模块对门架连接装置进行了有限元分析,并根据分析结构进行优化。5、根据图纸设计,通过整机试制,验证了设计图纸的正确性和合理性;通过整机试验,整机基本性能参数达到了设计要求,整机稳定性满足EN1726-1:1999附录H越野叉装机稳定性试验要求。
[Abstract]:At present, the domestic developed wheeled tractor products have been greatly improved in agricultural machinery and engineering variant application technology, especially the application of front loading and rear excavation has been basically improved. However, with the rapid development of agricultural mechanization and the intersection with other fields, the types of tractor operations are gradually increasing. More and more functions are required of tractors, and their engineering variant products tend to be diversified. In 2011, the state department "Analysis of Mechanical equipment requirements for the Construction of New Countryside" reports on farmland operations and feed production. The demand of forklift derivative product is analyzed in the field of new energy production, and the handling demand of agricultural material product is put forward. Against this background, it is necessary to develop a kind of fork-loading which is suitable for the operation of agricultural, pastoral and forestry fields where the ground or surface layer has been damaged in accordance with the requirements of the new generation of industrial, agricultural and new rural machinery and equipment. The fork can be used not only in loading and unloading, stacking and handling of materials, but also in handling, handling and transferring of materials in new rural construction, pipeline laying, wharf yard and so on. The main work of this paper is as follows: 1. Research on the demand for material handling vehicles in agriculture, animal husbandry, forestry and other industries. Through market investigation and discussion of the development status of related products at home and abroad. 2, according to the specific operation requirements and working environment, the four-drive tractor transmission system, supporting power 29.4 kW. Secondly, according to the requirements of the agriculture, animal husbandry, forestry and other industries for material handling vehicles, Determining the basic design parameters for 1.5 ton tractor fork loading: rated lifting mass of 1500 kg, maximum lifting height of 3300 mm, to ensure full display of the whole machine's four-wheel drive and off-road performance on an unleveled ground or ground where the surface is damaged, 3. On the basis of determining the basic parameters of 1.5-ton tractor fork loading, the main parts are selected and designed, including four-drive tractor transmission system, industrial forklift working device, Finally, the virtual prototype of 1.5-ton tractor fork loading is built by using Pro/E software, and the design of frame, roof frame and cover piece is completed, and the finite element analysis of the portal frame connection device is carried out through the Mechanica technology module embedded in the Pro/E software. The correctness and reasonableness of the design drawings are verified according to the drawing design, and the basic performance parameters of the whole machine meet the design requirements. The stability of the whole machine meets the requirements of EN1726-1:1999 Appendix H cross-country fork mounting stability test.
