[Abstract]:The multi adaptable operating platform for fast tunneling and anchorage not only improves the working environment of workers effectively, ensures the safety of workers' work, and improves the working efficiency of the driving and supporting. The walking mechanism is the key core of the rapid excavation and anchor multi adaptable operating platform to carry out the functions of transportation and braking, which can provide the safe and reliable work of the operating platform. The paper first systematically analyzes the structure and function principle of the digging and anchoring operation platform. According to the basic parameters of the operating platform, the design and selection of the walking mechanism of the driving platform are carried out. According to the actual working conditions of the walking mechanism, the working conditions under different conditions are analyzed and summed up, three kinds of slope. The walking direction of the two kinds of walking, the series parallel walking mode of the hydraulic cylinder and the horizontal turning, the two turning conditions of the vertical turning. Finally, the load of the driving anchor platform is analyzed and calculated, and the traction force of the walking hydraulic cylinder and the locking force of the locking hydraulic cylinder are calculated. The paper is based on the paper. The hydraulic system of driving mechanism of driving anchor platform is designed and the hydraulic system of driving mechanism is designed. The functions and sequence of various components of the hydraulic system are described in detail, and the logic relation is carried out. According to the working load, the parameters of the walking hydraulic cylinder and locking hydraulic cylinder are calculated, and the key hydraulic components are calculated. According to the principle diagram of the hydraulic system of the walking mechanism, the AMESim modeling and parameter setting are carried out. In the process of modeling, the displacement control load is applied in the modeling process. The displacement of the actuator, the dynamic characteristics of the speed and load parameters and the pressure of the inlet and outlet are simulated and analyzed. The working state of the key sequence valve is analyzed. The results show that the velocity impact of the walking mechanism is small and the impact is more obvious at the change of direction. The working pressure of the actuator is more stable, and the feasibility of the design of the walking mechanism is verified. The research work has achieved good results and laid a foundation for further research.
