Accessory control system and engineering machinery
The invention relates to the field of hydraulic multi-accessory switching control systems, and discloses an accessory control system and engineering machine.The accessory control system comprises a main valve, a first switching oil port, a second switching oil port and a switching overflow valve, the first working oil port of the main valve is connected with the first switching oil port through a first working oil way, and the second working oil port of the main valve is connected with the second switching oil port through a second working oil way; a second working oil port of the main valve is connected with the second switching oil port through a second working oil way; a switching function valve is arranged on the second working oil way, one end of a switching overflow valve is connected to the first working oil way, and the other end of the switching overflow valve is connected with an oil drainage oil way so as to adjust the working pressure of the first working oil way. And the problem of pipeline rematching or redesign caused by accessory replacement according to different working conditions can be solved.
本申请涉及液压用多属具切换控制系统领域，公开了一种属具控制系统及工程机械，该属具控制系统包括主阀、第一切换油口、第二切换油口和切换溢流阀，所述主阀的第一工作油口通过第一工作油路与所述第一切换油口连接，所述主阀的第二工作油口通过第二工作油路与所述第二切换油口连接；所述第二工作油路上设置有切换功能阀，所述切换溢流阀的一端连接在所述第一工作油路上，其另一端与泄油油路连接，以调节所述第一工作油路的工作压力。可以解决面对作业工况的不同，更换属具带来的重新配套或者重新设计管路的问题。
