[0002] The electric electro-hydraulic push rod is a hydraulically driven manipulator that integrates mechanics, electricity and hydraulics. It is suitable for reciprocating push-pull linear motion, and can also be used in places where workpieces need to be raised, lowered or clamped. The electric electro-hydraulic push rod has been widely used in metallurgy, mining, electricity, coal, machinery, transportation, food, chemical industry, cement, water conservancy, building materials, transportation and other industries.
[0003] As disclosed in the utility model patent with publication number: CN218862975U, an integral straight electro-hydraulic push rod comprises a motor and a hydraulic combination sleeve which is movably assembled and fixed to the motor at one side of the motor through an external flange, and a hydraulic cylinder is arranged at one end of the hydraulic combination sleeve away from the motor. In the utility model, the detachable push rod is movably assembled with the push rod main end, and the driving end of the push rod main end itself is relatively short. When the push rod main end produces fatigue wear under the driving work of the motor and the hydraulic combination sleeve and needs to be disassembled, the sealing plug can be removed from the inside of the screw hole, and the detachable push rod itself can be controlled to rotate slightly by inserting the overlong screw hole of the external disassembly rod into the disassembly groove, so that the detachable push rod itself and the push rod main end are loosened. At this time, the detachable push rod can be rotated from one end of the detachable push rod outside the hydraulic cylinder to take out the inside of the hydraulic cylinder and replace it, thereby achieving the effect of convenient and quick disassembly, removal and replacement of the detachable push rod itself.
[0004] Although the above-mentioned electric electro-hydraulic push rod can be disassembled for operation, it is not convenient to adaptively adjust the length of the push rod, so that the adaptability of the push rod is low when connected to different equipment, which reduces the practical performance of the electric electro-hydraulic push rod. Therefore, an integral straight electric electro-hydraulic push rod is urgently needed to solve the above-mentioned problems. Utility Model Content
