Abstract

This utility model discloses a hydraulic simulation training system for tunnel boring machines (TBMs), addressing the current lack of simulation training equipment for TBM hydraulic systems in related training programs. The system includes a cabinet with a simulation operating platform, hydraulic circuit interface, and control panel. The cabinet houses a hydraulic system and an electrical wiring system. The hydraulic system and hydraulic circuit interface are detachably connected to supply fluid to the hydraulic components on the simulation operating platform. The control panel contains electrical control components connected to the electrical wiring system and the hydraulic system. This utility model simulates the hydraulic control system of a TBM, allowing for direct observation of the status of each component during hydraulic control signal transmission, helping trainees familiarize themselves with the working principle of the TBM hydraulic system; and solving the current problem of lacking simulation training equipment for TBM hydraulic systems in related training programs.
