【摘要】：由于我國(guó)經(jīng)濟(jì)的迅速發(fā)展，對(duì)水泥混凝土路面建設(shè)的需求也在不斷增加，相應(yīng)之下對(duì)其維修的要求也在不斷增多。在常見的維修方法中碎石化法更具有優(yōu)勢(shì)，而此技術(shù)應(yīng)用的關(guān)鍵就是多錘頭水泥路面破碎機(jī)具。 本文結(jié)合實(shí)際課題的需要，以某公司的一種自行式水泥路面破碎機(jī)為研究對(duì)象，對(duì)其整體結(jié)構(gòu)設(shè)計(jì)、工作原理和工作步驟進(jìn)行了理論分析和計(jì)算。主要研究?jī)?nèi)容如下： 1、根據(jù)設(shè)備的功能，分析了該設(shè)備的結(jié)構(gòu)組成。確定了該設(shè)備的總體方案為在重卡底盤的基礎(chǔ)上增加了一套輔助輪機(jī)構(gòu)和兩套破碎錘機(jī)構(gòu)組成。這種方案既有破碎效率高的優(yōu)點(diǎn)，也有轉(zhuǎn)場(chǎng)速度快的優(yōu)點(diǎn)。 2、對(duì)該破碎設(shè)備的輔助輪提升機(jī)構(gòu)進(jìn)行了受力分析和結(jié)構(gòu)設(shè)計(jì)，確定了該設(shè)備輔助輪的驅(qū)動(dòng)方式。 3、確定該破碎設(shè)備的破碎錘機(jī)構(gòu)是由提錘機(jī)構(gòu)、翻轉(zhuǎn)機(jī)構(gòu)、平移機(jī)構(gòu)組成，對(duì)這些機(jī)構(gòu)的構(gòu)件進(jìn)行了受力分析和結(jié)構(gòu)設(shè)計(jì)。 4、該設(shè)備的輔助輪機(jī)構(gòu)和破碎錘機(jī)構(gòu)都是采用液壓驅(qū)動(dòng)。液壓系統(tǒng)可分為提錘液壓回路、行走回路和輔助回路，其中輔助回路用來完成輔助輪提升、破碎錘架翻轉(zhuǎn)和平移。完成了液壓系統(tǒng)的回路設(shè)計(jì)和元件選型。 5、由于行走機(jī)構(gòu)和工作機(jī)構(gòu)都是通過副車架與重卡底盤相連，副車架為重要的受力部件，因此對(duì)其通過有限元分析軟件ANSYS Workbench進(jìn)行了靜力學(xué)分析，得出了它的應(yīng)力分布和變形量云圖。 6、對(duì)該破碎機(jī)控制系統(tǒng)進(jìn)行了硬件設(shè)計(jì)和程序原理設(shè)計(jì)，，其主要硬件構(gòu)成有PLC、觸摸屏、接近開關(guān)、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.
