【摘要】：路缘石滑模摊铺机是一种通过特定模具铺出多种形状路缘石的工程机械,广泛应用于道路两边的路缘石、拦水带以及农业灌溉排水渠的施工。现阶段,我国对这种机械研究领域多为自走式滑模摊铺机的研究,对于牵引式滑模摊铺机的研究非常少,因此本文有必要对牵引式滑模摊铺机进行系统设计和研究分析。通过本文的研究,在国内外先进摊铺机械研究的基础上,形成关于牵引式滑模摊铺机系统性设计理论,对今后牵引式滑模摊铺机工程实际应用具有现实理论指导意义。本文主要内容包括:第一章总体介绍了课题的研究背景和意义,并详细阐述了国内外路缘石滑模摊铺机的发展趋势和应用领域。其中论文阐述了我国路缘石滑模摊铺机当前的研究现状和我国研究跟国外先进技术的差距何在。重点介绍了螺旋式和挤压式滑模摊铺机的各自优缺点,并重点讲述当前背景下研发牵引式路缘石滑模摊铺机重要意义,并阐述牵引式路缘石滑模摊铺机的市场前景和应用前景。第二章以秦皇岛卢龙华通工程机械厂生产的HT750滑模摊铺机为借鉴对象,并以牵引式路缘石滑模摊铺机为研究对象,介绍了该机的组成、应用范围及工作原理,分析计算了生产率、发动机功率等主要技术参数,同时对路缘石滑模摊铺机进行各个零部件的三维实体设计,并进行整体装配。第三章利用ANSYS软件,对牵引式路缘石滑模摊铺机的车轮轴、连杆等关键受力部件进行三维几何模型建立和线性静力结构分析。通过分析,列出了车轮轴、连杆的受力变形图、Mises等效应力云图,分析出了车轮轴易变形区域,找到了容易发生应力集中的区域,进而改善轴的材料、尺寸等参数。第四章利用ANSYS软件中的模态分析模块对滑模机的车轮轴进行有限元模态分析。论文了解车轮轴的共振区域,为结构设计提供一定的指导,得到对应前十五阶固有频率,得到对应的变形分布图。第五章根据牵引式滑模摊铺机的工况要求进行各个系统零部件的设计与选型,为液压调平系统的设计奠定了基础。同时,对摊铺机进行了装机试验以验证整机运行是否可靠。
[Abstract]:The road edge stone slide form paver is a kind of construction machinery which can spread various shapes of road edge stone by special mould. It is widely used in the construction of road edge stone, water retaining belt and agricultural irrigation drainage canal on both sides of the road. At present, the research of this kind of mechanical research field is mostly self-moving sliding form paver, but the research of traction sliding form paver is very few, so it is necessary for this paper to carry on the systematic design and research analysis to the traction sliding form paver. Based on the research of advanced paving machinery at home and abroad, the systematic design theory of traction sliding form paver is formed, which is of practical theoretical significance to the practical application of traction sliding form paver in the future. The main contents of this paper are as follows: in the first chapter, the research background and significance of the subject are introduced, and the development trend and application field of the road edge stone sliding form paver at home and abroad are described in detail. Among them, the paper expounds the current research status and the gap between our country's research and foreign advanced technology. This paper mainly introduces the advantages and disadvantages of spiral and extruded sliding form pavers, and emphasizes on the significance of developing traction slide form pavers on road edge under the current background, and expounds the market prospect and application prospect of traction slide form pavers. The second chapter takes the HT750 sliding form paver produced by Lulong Huatong Engineering Machinery Factory of Qinhuangdao as the reference object, and takes the traction type road edge stone slide form paver as the research object, introduces the composition, application scope and working principle of the machine. The main technical parameters, such as productivity and engine power, are analyzed and calculated. At the same time, the 3D solid design of each component is carried out and the whole assembly is carried out. In chapter 3, the three dimensional geometric model and the linear static structure analysis of the wheel shaft, connecting rod and other key force components of the traction road edge stone sliding form paver are established by using ANSYS software. Through analysis, the stress deformation diagram of wheel shaft and connecting rod, Mises equivalent stress cloud diagram are listed, the easy deformation region of wheel shaft is analyzed, and the region where stress concentration easily occurs is found, and then the material and dimension of axle are improved. In chapter 4, the modal analysis module of ANSYS software is used to analyze the wheel shaft of sliding mode machine by finite element method. In this paper, the resonance region of the wheel shaft is understood, which provides some guidance for the structural design, and obtains the first 15 natural frequencies and the corresponding deformation distribution map. In the fifth chapter, according to the working conditions of the traction sliding form paver, the design and selection of the parts and components of the system are carried out, which lays a foundation for the design of the hydraulic leveling system. At the same time, the paver is tested to verify the reliability of the machine.
