Problems solved by technology
[0002] The current hydraulically driven rotating device is generally provided with a rotating mechanism that rotates synchronously with the external rotating shaft in the inner cavity of the box frame, and then a hydraulic cylinder is installed outside the frame, and the rotating mechanism is connected with the piston rod of the hydraulic cylinder through a connecting rod. The reciprocating motion of the hydraulic cylinder piston rod drives the rotating mechanism to rotate, thereby driving the external rotating shaft to rotate. Its structure is complex and its volume is often large.

The invention discloses a hydraulic rotating mechanism. The hydraulic rotating mechanism comprises a mounting seat and a rotating ring capable of rotating; an annular sealing groove is formed betweenthe mounting seat and the rotating ring, and the rotating ring is provided with a blade for partitioning the sealing groove; a first oil inlet, a first oil outlet, a second oil inlet and a second oiloutlet which are used for oil input and output of the sealing groove are formed in the position, in the rotating direction of the rotating ring, of the mounting seat; the first oil inlet and the firstoil outlet are adjacent, a first telescopic plate capable of being inserted and quiting from the sealing groove is arranged between the first oil inlet and the first oil outlet, and when the first telescopic plate is inserted into the sealing groove, the sealing groove is partitioned into a first oil inlet cavity and a first oil return cavity jointly by the first telescopic plate and the blade; and the second oil inlet and the second oil outlet are adjacent, a second telescopic plate capable of being inserted and quiting from the sealing groove is arranged between the second oil inlet and thesecond oil outlet, and when the second telescopic plate is inserted into the sealing groove, the sealing groove is partitioned into a second oil inlet cavity and a second oil return cavity jointly bythe second telescopic plate and the blade. The blade is pushed to rotate through oil inlet by the two oil inlet cavities, and the structure is simple.
Description
【Technical field】 [0001] The invention relates to a hydraulic rotating mechanism. 【Background technique】 [0002] The current hydraulically driven rotating device is generally provided with a rotating mechanism that rotates synchronously with the external rotating shaft in the inner cavity of the box frame, and then a hydraulic cylinder is installed outside the frame, and the rotating mechanism is connected with the piston rod of the hydraulic cylinder through a connecting rod. The reciprocating motion of the hydraulic cylinder piston rod drives the rotating mechanism to rotate, thereby driving the external rotating shaft to rotate. Its structure is complex and its volume is often large. [0003] The present invention is made based on this situation. 【Content of invention】 [0004] The object of the present invention is to overcome the shortcomings of the prior art and provide a hydraulic rotating mechanism with simple structure and small volume. [0005] The present inv...
