Embodiment Construction
[0013] The present invention will be further described below in conjunction with specific drawings.
[0014] like figure 1 As shown, the two-cylinder split type electro-hydraulic push rod is mainly composed of a motor 1, a coupling 2, a gear pump 3, an air filter 4, an integrated block 5 and an oil cylinder assembly 7; the motor 1 passes through the coupling 2 It is connected with the gear pump 3, the air filter 4 is connected with the gear pump 3, and the gear pump 3 is connected with the integrated block 5; the oil cylinder assembly 7 and the gear pump 3 have a split structure, and are connected with the integrated block 5 through the pipeline 6; At least two oil cylinder assemblies 7 are connected to the same gear pump 3, and the pipeline 6 is a high-pressure oil pipe, and rubber hose can be used. Preferably, the gear pump 3 is arranged on the pump base 8 .
[0015] When working, the motor 1 drives the gear pump 3 to forward and reverse through the high-pressure oil pipe ...

The invention discloses a double-cylinder split type electric hydraulic push rod. The double-cylinder split type electric hydraulic push rod comprises a motor, a coupler, a gear pump, an integrated block and oil cylinder assemblies; the oil cylinder assemblies and the bearing pump which are separately arranged are connected through two pipelines; the two oil cylinder assemblies are connected to the bearing pump. The double-cylinder split type electric hydraulic push rod has the advantages of enabling a pump body and oil cylinders to be separated and enabling two connecting openings which are connected through the high pressure rubber pipes are added on the basis of an original electric hydraulic push rod, enabling a user to select a plurality of installation ways (trunnion connection, flange connection, hanging ring connection and the like) which are designed for the oil cylinders, enabling the user to select different sealing parts according to on-site temperature, greatly saving costs due to the fact that the pump body is far from the equipment, enabling the sealing parts of the oil cylinders or oil tanks to be convenient and rapid to replace when get aged, greatly saving manpower, materials, financial resources and time, being stable, small in installation space, suitable for equipment which requires high-temperature high-altitude dangerous environments and one-station double cylinders in compared with an integral type electric hydraulic push rod.
Description
technical field [0001] The invention relates to electro-hydraulic push rod technology, in particular to a double-cylinder split type electro-hydraulic push rod. Background technique [0002] At present, the electro-hydraulic push rod is suitable for reciprocating push-pull linear (or reciprocating rotation at a certain angle) motion. It can be used in places where the work is raised, lowered or clamped, and it can also be used in long-distance and high-altitude dangerous areas, and it can be centralized with a computer network. (program) control. It has been widely used in metallurgy, mining, coal, electric power, machinery, grain, cement, chemical industry, water conservancy, transportation and other industries, and is an indispensable general power source. [0003] The electro-hydraulic push rod has reliable overload protection performance. Even if it is overloaded or moves to the end of the stroke, the motor will still run normally, but it will not burn or damage other p...
