Abstract

The invention discloses a parallel compact-type electro-hydraulic push rod which comprises a motor, an oil pump, a hydraulic manifold block, an oil tank and an oil cylinder, wherein the motor is provided with a motor shaft; the oil pump is provided with an oil pump shaft; the oil cylinder is detachably arranged at the bottom of the oil tank through a bracket which is connected to the oil tank; the hydraulic manifold block is connected with a reversing valve on the oil tank through a pipeline; the reversing valve is connected with a manual pump and connected with two ends of the oil cylinder through pipelines; a concave hole is arranged on the end surface of the motor shaft which is connected with the oil pump shaft; the oil pump shaft is provided with a convex body which is matched with the concave hole; and the concave hole and the convex body are connected through a key. The push rod is simple and practical; and components such as a motor coupling, a pump coupling, a motor base, an elastic plum-blossom rubber ring and the like are omitted so that the structure is more compact, the volume of the electro-hydraulic push rod is decreased, the transportation and the installation are more convenient, and the production and manufacture costs are lowered simultaneously.

Description

technical field [0001] The invention discloses a hydraulic mechanical device, in particular to a parallel electro-hydraulic push rod. Background technique [0002] Electro-hydraulic push rod The electro-hydraulic push rod is divided into integral straight type, parallel type and split type. It uses the motor as the power source, and the motor rotates in the forward (reverse) direction to make the hydraulic oil output pressure oil through the two-way oil pump and integrate it through the oil circuit. The valve block is sent to the working cylinder to realize the reciprocating movement of the piston rod. The motor and the oil pump of the conventional electro-hydraulic push rod are connected by a coupling. The motor is energized, the motor shaft rotates, the motor shaft is connected with the motor coupling through the key, and drives the motor coupling to rotate, and the motor coupling drives the pump coupling to rotate through the elastic plum blossom rubber ring, and the pum...
