Hydraulic safety system and wheeled excavator
The invention provides a hydraulic safety system and a wheeled excavator, and relates to the technical field of excavators. The technical problem that when excavator power breaks down, urgent danger prevention cannot be achieved through a steering system is solved to a certain degree. The hydraulic safety system comprises an oil supply device, a steering device, a brake valve set, a liquid charging device and an energy accumulator. The oil supply device is connected with the steering device through a first oil way, and the steering device transmits a steering signal to the oil supply device through a control oil way. The oil supply device is connected with the liquid charging device through a second oil way, and the liquid charging device is used for filling the energy accumulator with hydraulic oil. The brake valve set communicates with a brake oil way, the energy accumulator communicates with an energy accumulating oil way, and the energy accumulating oil way communicates with the brake oil way and the first oil way.
本发明提供的一种液压安全系统及轮胎式挖掘机，涉及挖掘机技术领域，以在一定程度上解决挖掘机动力发生故障时，无法通过转向系统紧急避险的技术问题。本发明提供的液压安全系统,包括供油装置、转向器、刹车阀组、充液装置以及蓄能器；供油装置通过第一油路与转向器相连接，转向器通过控制油路将转向信号传递至供油装置；供油装置通过第二油路连通充液装置，充液装置用于向蓄能器内补充液压油；刹车阀组连通有刹车油路，蓄能器连通有蓄能油路，且蓄能油路分别与刹车油路和第一油路相连通。
