【摘要】：单轨吊作为煤矿辅助运输的一种新型装备广泛应用于煤矿辅助运输。井下工况复杂,确保单轨吊机车安全工作成为一个非常关键的问题,本文旨在通过对与单轨吊安全性能密切相关的夹紧系统、制动系统与起吊系统的研究,以提高单轨吊机车的安全性能。本文根据重型柴油机单轨吊起吊梁实际井下工作状况,针对与安全性能密切相关的夹紧系统、制动系统与起吊系统的液压工作原理进行了分析。根据重型柴油机单轨吊的设计参数,确定夹紧缸的结构参数,研究单轨吊制动系统的组成,设计外置式制动模块,推导出了紧急制动实现的条件。分析插装阀受力情况,导出了插装阀控制腔弹簧开口量x与制动缸有杆腔的压力pB的之间关系,根据重型柴油机单轨吊的设计参数计算出制动弹簧力,确定了制动弹簧和制动缸的参数,并用Solidworks/Routing对制动装置做液压管路的布路分析。研究重型起吊梁的主要结构组成,依据其日常工作要求,确定起吊液压缸的参数。计算了驱动轮的夹紧力,验证了系统提供的牵引力能够满足工作要求。确定了起吊载荷和坡道倾角θ之间的关系,并利用MATLAB软件实现起吊载荷和坡道倾角θ之间的关系的可视化。确定起吊所用链条的参数。利用Solidworks/Simulition对起吊梁做有限元分析。利用Solidworks/Motion做运动分析。分别用FluidSIM、MATLAB/simscape、AMESim为夹紧、起吊以及制动液压系统建模,结合柴油机单轨吊实际的工作状况对主要元件的子模型参数进行设置,并对仿真结果进行分析。结果表明夹紧、制动和起吊系统能够完成预期的工作,验证了液压系统的正确性。样机生产完成后,在模拟煤矿井下条件的轨道上进行试验,结果满足设计和试验要求。同时对夹紧、制动和起吊系统的分析研究有助于今后重型柴油机单轨吊的改进。
[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.
