Abstract
The invention provides a hydraulic synchronizing circuit. Comprising three pressure sensors (1), two oil cylinders (2), three two-position one-way stop valves (3), a two-position two-way stop valve (4), a weight (5), a synchronous motor (6) and a three-position reversing valve (7). Rod cavities of the two oil cylinders (2) are respectively provided with a pressure sensor (1), and the parallel connection position of the rod cavities of the two oil cylinders (2) is provided with a pressure sensor (1); plug cavities of the two oil cylinders (2) are connected with two oil outlets of the synchronous motor (6) through the two-position one-way stop valves (3); the two-position two-way stop valve (4) is arranged between two oil outlets of the synchronous motor (6); an A port end of the three-position reversing valve (7) is connected with an oil inlet of the synchronous motor (6); and a PT port of the three-position reversing valve (7) is connected with a power oil way. The high-precision synchronous loop is high in precision, simple and reliable.
