Problems solved by technology

At present, most of them use the hydraulic system locking circuit to achieve locking and positioning. However, due to the unavoidable oil leakage of the internal components of the hydraulic system, long-term locking will cause hydraulic leakage, resulting in slippage of the piston rod, which will affect the efficiency of the equipment. and security

Abstract

The invention relates to a unidirectional mechanical locking hydraulic cylinder and belongs to the field of a hydraulic cylinder. The unidirectional mechanical locking hydraulic cylinder comprises a hollow cylinder body and a piston rod; one end of the piston rod is positioned in the cylinder body; a wedged stop block is arranged at one end, positioned in the cylinder body, of the piston rod; thedirection of a wedge tip of the wedged stop block is arranged along the axis direction of the piston rod; a limiting stop block is arranged on the piston rod on one side of the wedge tip of the wedgedstop block; the limiting stop block is positioned in the cylinder body; a plurality of balls cooperatively used with the wedged stop block are arranged between the wedged stop block and the limitingstop block; an annular floating piston is arranged on the piston rod on one side of the bottom end of the wedged stop block; a push rod for pushing the positions of the balls is arranged on one side,near the balls, of the floating piston; the push rod performs reciprocating sliding together with the floating piston in a gap between the wedged stop block and the cylinder body; and the unidirectional mechanical locking hydraulic cylinder can realize unidirectional mechanical locking, can avoid displacement of the piston rod, is simple in structure and convenient to lock and can effectively reduce the slip risk of the hydraulic cylinder.

Description

technical field [0001] The invention belongs to the field of hydraulic cylinders and relates to a one-way mechanical locking hydraulic cylinder. Background technique [0002] Hydraulic cylinders are widely used in mechanical equipment that requires positioning and locking, such as leveling devices, guide rail locking devices, rolling mill locking devices, radar positioning devices, etc. During use, the piston rod of the hydraulic cylinder usually needs to be positioned in a certain position for a long time without displacement. At present, most of them use the hydraulic system locking circuit to achieve locking and positioning. However, due to the unavoidable oil leakage of the internal components of the hydraulic system, long-term locking will cause hydraulic leakage, resulting in slippage of the piston rod, which will affect the efficiency of the equipment. and security. Contents of the invention [0003] In view of this, the object of the present invention is to provi...
