Abstract

The invention relates to the field of machinery, and in particular relates to a frame lifting control device of an active carry scraper. The active carry scraper comprises a hydraulic pump, a left pitching oil cylinder and a right pitching oil cylinder, wherein the left end and the lower end of the left pitching oil cylinder are respectively hinged with a frame and a left driving gear; and the upper end and the lower end of the right pitching oil cylinder are respectively hinged with the frame and a right driving gear. The frame lifting control device comprises a left position sensor, a rightposition sensor, a controller, an operating handle and an electronic-control hydraulic control valve, wherein the left position sensor is used for measuring the position of the left pitching oil cylinder; the right position sensor is used for measuring the position of the right pitching oil cylinder; the electronic-control hydraulic control valve is connected onto an oil line among the hydraulic pump, the left pitching oil cylinder and the right pitching oil cylinder; the input end of the controller is connected with the left position sensor and the right position sensor; the output end of the controller is connected with the control end of the electronic-control hydraulic control valve; and the controller outputs a control signal to the electronic-control hydraulic control valve. Becausethe left position sensor, the right position sensor and the controller carry out real-time measuring control, the frame is precisely controlled to lift.
