Engineering machinery hydraulic control system and engineering machinery
The invention relates to the field of hydraulic pressure, and discloses an engineering machinery hydraulic control system and engineering machinery. The hydraulic control system comprises an oil cylinder; the main pump system is connected with the oil cylinder through a first oil inlet path, and a first reversing valve is arranged on the first oil inlet path; the gear pair comprises a first gear and a second gear which are meshed with each other, and the tooth number of the second gear is larger than that of the first gear; the motor is coaxially connected with the first gear, the driving pump is coaxially connected with the second gear, the motor is connected to the main pump system through a second oil inlet path, a second reversing valve is arranged on the second oil inlet path, and an oil outlet of the driving pump is connected to a rodless cavity of the oil cylinder through a booster oil path; the boosting switch is in signal connection with the controller and used for sending a boosting signal or a closing signal to the controller, and the controller controls the first reversing valve and the second reversing valve to reverse according to the received boosting signal or closing signal. According to the scheme, only the driving pump is pressurized, other elements of the whole machine are not affected, the service life of related elements can be guaranteed, and cost is reduced.
本发明涉及液压领域，公开了一种工程机械液压控制系统及工程机械。液压控制系统包括油缸；主泵系统通过第一进油路与油缸连接，第一进油路上设有第一换向阀；齿轮副包括相啮合的第一齿轮和第二齿轮，第二齿轮的齿数大于第一齿轮的齿数；马达与第一齿轮同轴连接，驱动泵与第二齿轮同轴连接，马达通过第二进油路连接至主泵系统，第二进油路上设有第二换向阀，驱动泵的出油口通过升压油路连接至油缸的无杆腔；升压开关与控制器信号连接，用于向控制器发送升压信号或关闭信号，控制器根据接受到的升压信号或关闭信号，控制第一换向阀和第二换向阀换向。该方案只对驱动泵进行增压，不影响整机的其他元件，可保证相关元件的使用寿命，成本降低。
