[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.
