【摘要】：單軌吊作為煤礦輔助運輸的一種新型裝備廣泛應用于煤礦輔助運輸。井下工況復雜,確保單軌吊機車安全工作成為一個非常關鍵的問題,本文旨在通過對與單軌吊安全性能密切相關的夾緊系統、制動系統與起吊系統的研究,以提高單軌吊機車的安全性能。本文根據重型柴油機單軌吊起吊梁實際井下工作狀況,針對與安全性能密切相關的夾緊系統、制動系統與起吊系統的液壓工作原理進行了分析。根據重型柴油機單軌吊的設計參數,確定夾緊缸的結構參數,研究單軌吊制動系統的組成,設計外置式制動模塊,推導出了緊急制動實現的條件。分析插裝閥受力情況,導出了插裝閥控制腔彈簧開口量x與制動缸有桿腔的壓力pB的之間關系,根據重型柴油機單軌吊的設計參數計算出制動彈簧力,確定了制動彈簧和制動缸的參數,并用Solidworks/Routing對制動裝置做液壓管路的布路分析。研究重型起吊梁的主要結構組成,依據其日常工作要求,確定起吊液壓缸的參數。計算了驅動輪的夾緊力,驗證了系統提供的牽引力能夠滿足工作要求。確定了起吊載荷和坡道傾角θ之間的關系,并利用MATLAB軟件實現起吊載荷和坡道傾角θ之間的關系的可視化。確定起吊所用鏈條的參數。利用Solidworks/Simulition對起吊梁做有限元分析。利用Solidworks/Motion做運動分析。分別用FluidSIM、MATLAB/simscape、AMESim為夾緊、起吊以及制動液壓系統建模,結合柴油機單軌吊實際的工作狀況對主要元件的子模型參數進行設置,并對仿真結果進行分析。結果表明夾緊、制動和起吊系統能夠完成預期的工作,驗證了液壓系統的正確性。樣機生產完成后,在模擬煤礦井下條件的軌道上進行試驗,結果滿足設計和試驗要求。同時對夾緊、制動和起吊系統的分析研究有助于今后重型柴油機單軌吊的改進。
[Abstract]:Monorail crane is widely used in coal mine auxiliary transportation as a new type of equipment. The underground working condition is complex, so it becomes a very key problem to ensure the safety of monorail crane. This paper aims to study the clamping system, braking system and hoisting system, which are closely related to the safety performance of monorail crane. In order to improve the safety performance of monorail locomotives. According to the actual downhole working condition of heavy duty diesel engine monorail lifting beam, the hydraulic working principle of clamping system, braking system and hoisting system, which is closely related to safety performance, is analyzed in this paper. According to the design parameters of monorail crane of heavy duty diesel engine, the structural parameters of clamping cylinder are determined, the composition of braking system of monorail crane is studied, the external braking module is designed, and the condition of emergency braking is deduced. Based on the analysis of the stress of the cartridge valve, the relationship between the opening amount of the spring of the valve control cavity x and the pressure PB of the brake cylinder with a rod cavity is derived, and the braking spring force is calculated according to the design parameters of the monorail crane of heavy duty diesel engine. The parameters of brake spring and brake cylinder are determined, and the hydraulic piping of brake device is analyzed by Solidworks/Routing. The main structure composition of heavy lifting beam is studied and the parameters of lifting hydraulic cylinder are determined according to its daily working requirements. The clamping force of the drive wheel is calculated, and it is verified that the traction provided by the system can meet the working requirements. The relationship between lifting load and ramp inclination 胃 is determined, and the relationship between lifting load and ramp inclination 胃 is visualized by MATLAB software. Determine the parameters of the chain used for lifting. The finite element analysis of lifting beam is done by Solidworks/Simulition. Use Solidworks/Motion to do motion analysis. The hydraulic system of clamping, hoisting and braking is modeled with FluidSIMB / MATLAB / AMESim, and the sub-model parameters of main components are set according to the actual working conditions of diesel engine monorail crane, and the simulation results are analyzed. The results show that the clamping, braking and lifting systems can accomplish the expected work, and the correctness of the hydraulic system is verified. After the prototype production is finished, the test is carried out on the track simulating the underground conditions of coal mines, and the results meet the design and test requirements. At the same time, the analysis and research of clamping, braking and lifting system are helpful to the improvement of heavy duty diesel engine monorail crane in the future.
