【摘要】：由于我国经济的迅速发展，对水泥混凝土路面建设的需求也在不断增加，相应之下对其维修的要求也在不断增多。在常见的维修方法中碎石化法更具有优势，而此技术应用的关键就是多锤头水泥路面破碎机具。 本文结合实际课题的需要，以某公司的一种自行式水泥路面破碎机为研究对象，对其整体结构设计、工作原理和工作步骤进行了理论分析和计算。主要研究内容如下： 1、根据设备的功能，分析了该设备的结构组成。确定了该设备的总体方案为在重卡底盘的基础上增加了一套辅助轮机构和两套破碎锤机构组成。这种方案既有破碎效率高的优点，也有转场速度快的优点。 2、对该破碎设备的辅助轮提升机构进行了受力分析和结构设计，确定了该设备辅助轮的驱动方式。 3、确定该破碎设备的破碎锤机构是由提锤机构、翻转机构、平移机构组成，对这些机构的构件进行了受力分析和结构设计。 4、该设备的辅助轮机构和破碎锤机构都是采用液压驱动。液压系统可分为提锤液压回路、行走回路和辅助回路，其中辅助回路用来完成辅助轮提升、破碎锤架翻转和平移。完成了液压系统的回路设计和元件选型。 5、由于行走机构和工作机构都是通过副车架与重卡底盘相连，副车架为重要的受力部件，因此对其通过有限元分析软件ANSYS Workbench进行了静力学分析，得出了它的应力分布和变形量云图。 6、对该破碎机控制系统进行了硬件设计和程序原理设计，，其主要硬件构成有PLC、触摸屏、接近开关、控制面板等。
[Abstract]:Due to the rapid development of economy in our country, the demand for cement concrete pavement construction is increasing, and accordingly, the requirement for its maintenance is increasing. Among the common maintenance methods, the crushing and petrochemical method has more advantages, and the key to the application of this technology is the multi-hammer cement pavement crushing machine. In this paper, a kind of self-propelled cement road crusher of a company is taken as the research object, and the whole structure design, working principle and working steps of the crusher are analyzed and calculated theoretically according to the needs of the practical subject. The main research contents are as follows: 1. According to the function of the equipment, the structure of the equipment is analyzed. The overall scheme of the equipment is to add a set of auxiliary wheel mechanism and two sets of crushing hammer mechanism on the basis of the heavy truck chassis. This scheme not only has the advantages of high crushing efficiency, but also has the advantages of fast transition speed. 2. The mechanical analysis and structural design of the auxiliary wheel lifting mechanism of the crushing equipment are carried out, and the driving mode of the auxiliary wheel of the equipment is determined. 3. It is determined that the crushing hammer mechanism of the crushing equipment is composed of a lifting hammer mechanism, a turning mechanism and a translation mechanism. The mechanical analysis and structural design of the members of these mechanisms are carried out. 4, the auxiliary wheel mechanism and crushing hammer mechanism of the equipment are driven by hydraulic pressure. Hydraulic system can be divided into hydraulic circuit of lifting hammer, walking circuit and auxiliary circuit, in which the auxiliary circuit is used to complete the lifting of auxiliary wheel, the turning and moving of broken hammer frame. The circuit design and component selection of hydraulic system are completed. 5, because the walking mechanism and the working mechanism are connected with the heavy truck chassis through the auxiliary frame, the auxiliary frame is an important force-bearing component, so the statics analysis is carried out through the finite element analysis software ANSYS Workbench. The stress distribution and deformation cloud diagram are obtained. 6. The hardware design and program principle design of the crusher control system are carried out. The main hardware is composed of PLC, touch screen, proximity switch, control panel and so on.
