【摘要】：隨著采礦事業(yè)的飛速發(fā)展,作為露天礦山運輸?shù)闹匾O備之一礦用汽車也日益向大型化發(fā)展,108噸和154噸電動輪礦用汽車越來越得到廣泛的使用。由于礦用汽車輪胎外形尺寸大、重量大,因此其拆裝搬運難度較大。同時,采用早前的人工方法進行輪胎的拆裝,不僅拆裝效率低、人工勞動強度大,而且極易造成事故的發(fā)生。因此,在礦山作業(yè)中,必須配有專用的設備,才能順利完成大型礦用汽車輪胎的拆裝工作,這種專用設備輪胎拆裝機就得到廣泛的應用。露天礦用汽車輪胎拆裝機主要是由工作裝置輪胎機械手與工程機械叉車或裝載機組裝而成,其功能主要用于金屬礦山、非金屬礦山及水電工程大型載重汽車輪胎的拆裝、搬運及碼垛的工作。本論文主要是以某公司的LCZ-40型重型礦山用汽車輪胎拆裝機為研究對象,該型號輪胎機械手主要靠液壓驅動,利用該機械手與叉車的聯(lián)合作用,可以完成實現(xiàn)輪胎的夾持、左右平移、側向翻轉、輪胎翻轉,同時可以完成整個裝置的舉升、前后傾等動作。首先,利用專用的三維設計軟件SOLIDWORKS,依據(jù)圖紙要求,完成工作裝置輪胎機械手的各零部件建模。在此過程中,根據(jù)工作性能要求,進行液壓缸、輪胎的簡單設計與建模,然后將機械手零部件和簡化模型液壓缸、輪胎組裝成整機模型。其次,利用SOLIDWORKS數(shù)據(jù)接口,把整機模型導入到ADAMS中完成機械手剛性系統(tǒng)的建立。最后,利用有限元分析軟件ANSYS,把輪胎機械手中需要柔性化的三維零件生成零部件的模態(tài)中性文件;然后,在所建立的機械手剛性系統(tǒng)中,利用生成的模態(tài)中性文件把輪胎、液壓桿剛性體零件替換成柔性體,建立輪胎機械手整機的剛柔耦合系統(tǒng)。在完成了剛柔耦合建模后,在軟件ADAMS中對該機械手的輪胎翻轉和整個工作裝置側向擺動進行運動仿真。通過比較剛性系統(tǒng)和剛柔耦合系統(tǒng)的仿真結果,驗證剛柔耦合系統(tǒng)更加符合現(xiàn)實,數(shù)據(jù)更加準確。最后,由于夾盤零件的重要性,在ANSYS中完成夾盤的靜強度分析和模態(tài)分析,驗證夾盤的強度能很好的滿足工作要求。
[Abstract]:With the rapid development of mining industry, as one of the important equipment of open-pit mine transportation, mining vehicles are increasingly developed to the large-scale development of 108-ton and 154-ton electric wheel mining vehicles are more and more widely used. Because of the large size and heavy weight of the tire, it is difficult to disassemble and assemble the tire. At the same time, the earlier manual method is not only low efficiency, labor intensity, but also easy to cause accidents. Therefore, in the mine operation, must be equipped with special equipment, in order to successfully complete the demolition and assembly of large mining vehicle tires, this kind of special equipment tire disassembly machine has been widely used. The automobile tire disassembly machine used in opencast mine is mainly composed of working device tire manipulator and construction machinery forklift truck or loader. Its function is mainly used in metal mines, non-metal mines and large truck tyres in hydropower projects, the function of which is mainly used in the disassembly and assembly of heavy truck tyres in metal mines, non-metallic mines and hydropower projects. Handling and palletizing work. This paper mainly takes the LCZ-40 heavy duty mine tire disassembly machine of a certain company as the research object. The tire manipulator of this model mainly depends on the hydraulic drive, using the combined action of the manipulator and the forklift truck, it can realize the tire clamping. Translation of left and right, lateral flip, tire flip, while the whole device can be lifted, forward and back tilt and other actions. Firstly, using the special 3D design software SOLIDWORKS, according to the drawing requirements, the modeling of the parts and components of the tire manipulator of the working device is completed. In the process, according to the performance requirements, the simple design and modeling of the hydraulic cylinder and tire are carried out, and then the manipulator parts and the simplified model hydraulic cylinder are assembled into the whole machine model. Secondly, using SOLIDWORKS data interface, the whole machine model is imported into ADAMS to complete the establishment of manipulator rigid system. Finally, using finite element analysis software ANSYS, the modal neutral files of the parts are generated from the three-dimensional parts of the tire manipulator which need flexibility. Then, in the rigid system of the manipulator, the tire is generated by using the generated modal neutral file. The rigid part of hydraulic rod is replaced with flexible body, and the rigid and flexible coupling system of tire manipulator is established. After the rigid-flexible coupling modeling is completed, the tire turnover of the manipulator and the lateral swing of the whole working device are simulated in the software ADAMS. By comparing the simulation results of rigid system and rigid-flexible coupling system, it is proved that the rigid-flexible coupling system is more realistic and the data is more accurate. Finally, due to the importance of the chuck parts, the static strength analysis and modal analysis of the chuck are completed in ANSYS to verify that the strength of the chuck can meet the requirements of the work well.
