Therefore, by providing the upper check valve 18 and the lower check valve 19, the present invention can smoothly perform the operations of filling and discharging oil when it is first put into use, thereby effectively ensuring the practical effects of the present invention.
Because the threaded connection between the upper conduction section 1802 and the upper fixing plug 1803 and the threaded connection between the lower conduction section 1902 and the lower fixing plug 1303 are arranged in a clearance manner, not only can the first oil guide hole 13 of the upper conduction section 1802 and the upper cylinder left piston rod 402, but also the second oil guide hole 16 of the lower conduction section 1902 and the lower cylinder right piston rod 503 be communicated with each other, and a damping hole can be formed, and when oil is leaked in the upper oil cylinder left cavity 4011 and the lower oil cylinder left cavity 5011 or too much oil is leaked in the use process, automatic oil supplement and oil drainage can be performed in time, so that the practical effect of the oil cylinder is greatly improved.
When the invention is used in normal times: hydraulic oil enters the upper cylinder right cavity 4012 through the first oil guide hole 13 and the first oil guide branch hole 14 of the upper cylinder right piston rod 403 to push the upper cylinder body 401 to move rightwards; under the extrusion of the upper cylinder piston 12, the hydraulic oil in the upper cylinder left cavity 4011 enters the second oil guide hole 16 of the lower cylinder left piston rod 502 along the first oil guide hole 13 and the first oil guide hole 14 of the upper cylinder left piston rod 402 in equal quantity, and enters the lower cylinder left cavity 5011 along the second oil guide hole 17, so as to synchronously push the lower cylinder body 501 to move leftwards, and the upper cylinder body 401 and the lower cylinder body 501 can be effectively driven to realize synchronous opposite movement, that is, a group of fork seats 6 is driven to realize synchronous opposite movement. On the contrary, the hydraulic oil enters the lower cylinder right cavity 5012 through the second oil guide hole 16 and the second oil guide branch hole 17 of the lower cylinder right piston rod 503 to push the lower cylinder body 501 to move rightwards; under the extrusion of the lower cylinder piston 15, the hydraulic oil in the lower cylinder left cavity 5011 equally enters the first oil guide hole 13 of the upper cylinder left piston rod 402 along the second oil guide hole 17 and the second oil guide hole 16 of the lower cylinder left piston rod 502, and enters the upper cylinder left cavity 4011 along the first oil guide hole 14, so as to synchronously push the upper cylinder body 401 to move leftwards, and thus the upper cylinder body 401 and the lower cylinder body 501 can be effectively driven to realize synchronous back-to-back movement, i.e. a group of fork seats 6 is driven to realize synchronous back-to-back movement. Compared with the existing synchronous oil cylinder, the synchronous driving device has the advantages that the upper oil cylinder body 401 and the lower oil cylinder body 501 can be precisely and synchronously driven without additionally arranging components such as a displacement sensor, the structure is simple, and the driving synchronism of the upper oil cylinder body 401 and the lower oil cylinder body 501 can be effectively ensured; and the upper oil cylinder 4 and the lower oil cylinder 5 of the oil-gas separator have the advantage of less oil leakage points in the process of matching use.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that it is obvious to those skilled in the art that various modifications and improvements can be made without departing from the principle of the present invention, and these modifications and improvements should also be considered as the protection scope of the present invention.
