Description

Oil tank assembly for electrohydraulic integrated push rod Technical Field The utility model relates to the technical field of electro-hydraulic push rods, in particular to an oil tank assembly for an electro-hydraulic integrated push rod. Background The electrohydraulic push rod is a hydraulic driving manipulator integrating machine, electricity and liquid, is suitable for reciprocating push-pull straight reciprocating rotation at a certain angle, is driven by a servo motor, a cylinder and the like in general, and is widely applied to the departments of metallurgy, mine, electric power, coal, machinery, traffic, grain, chemical industry, cement, water conservancy, building materials, transportation and the like. In the use process, the electrohydraulic push rod drives the bidirectional gear pump to positively and negatively output pressure oil by controlling the servo motor to positively and negatively rotate, the pressure oil is sent to the oil cylinder through the hydraulic control valve, the reciprocating motion of the piston rod of the oil cylinder is also realized, and then the basic working mode of the hydraulic pump is realized, the existing oil tank assembly is mainly integrated with the hydraulic cylinder and the hydraulic control valve, and the independent connection of the oil tank assembly and the hydraulic cylinder and the hydraulic control valve cannot be realized, so that the internal components of the oil tank assembly are independently maintained, the maintenance process is simplified, and therefore, the oil tank assembly which can be connected with the hydraulic cylinder and the hydraulic control valve in a split manner is required. Disclosure of utility model The utility model aims to solve the technical problem of providing an oil tank assembly for an electrohydraulic integrated push rod, which can be connected with a hydraulic cylinder and a hydraulic control valve in a split way, so that independent maintenance of internal components of the oil tank assembly is facilitated. In order to solve the technical problems, the technical scheme adopted by the utility model is as follows. The oil tank assembly for the electro-hydraulic integrated push rod comprises an oil tank main body, an oil tank inner cavity is formed in the center of the oil tank main body, a mounting flange convenient to connect with a hydraulic cylinder is arranged at the front end of the oil tank main body, an ear plate convenient to connect with a valve block is arranged on the periphery of the tail end of the oil tank main body, two oil tank oil delivery pipes which are arranged oppositely are arranged on the side wall of the oil tank main body, oil outlets of the oil tank oil delivery pipes are respectively connected with an oil pipe on the hydraulic cylinder, an oil inlet of the oil tank oil delivery pipe is connected with the valve block, an oil suction pipe communicated with a bidirectional gear pump is arranged on the side wall of the oil tank main body, and the other end of the oil suction pipe is communicated with the valve block. Above-mentioned oil tank assembly for integrated push rod of electricity liquid, still be provided with on the oil tank main part lateral wall with the oil tank oil feed pipe and the oil tank exhaust seat of oil tank inner chamber intercommunication, oil tank oil feed pipe and oil tank intercommunication.
