Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic devices, and in particular relates to a hydraulic push rod device. Background Art

[0002] The electro-hydraulic push rod is a hydraulically driven manipulator that integrates mechanical, electrical and hydraulic functions. It is suitable for applications that require reciprocating push-pull linear motion (or reciprocating rotation at a certain angle). It can also be used in places where workpieces need to be raised, lowered or clamped, and can achieve centralized or automatic control in remote dangerous areas.

[0003] The existing hydraulic push rods still have some defects. Most of them do not have the installation and positioning function. When fixing the sealing cover, it is necessary to manually hold the sealing cover and align the sealing cover with the fixing hole of the hydraulic push rod, and use the other hand to hold the wrench to fix the bolt. The process is relatively troublesome. For this reason, we propose a hydraulic push rod device. Utility Model Content
