Abstract

The invention relates to a self-restoration single-action type hydraulic cylinder. The self-restoration single-action type hydraulic cylinder comprises a cylinder bottom, a cylinder body, a piston, a piston rod and a cylinder cover, wherein the cylinder bottom is welded at one end of the cylinder body; the cylinder cover is arranged at the other end of the cylinder body; the piston is arranged in the cylinder body; one end of the piston rod extends into the cylinder body through the cylinder cover and is connected with the piston; an oil cavity is formed between the piston and the cylinder bottom in the cylinder body; and an oil conveying hole is formed on the cylinder bottom and communicated with the oil cavity. The self-restoration single-action type hydraulic cylinder is characterized by also comprising a spring and a pull rod, wherein a fixed part is arranged on the inner bottom surface of the cylinder bottom; a center hole is formed on the piston rod corresponding to the fixed part; the pull rod is arranged at the bottom of the center hole; and one end of the spring is connected with the fixed part, and the other end of the spring is connected with the pull rod. The self-restoration single-action type hydraulic cylinder has the advantage of rapidness and reliability in restoration of a single-action type hydraulic cylinder.

Description

technical field [0001] The invention relates to a single-acting hydraulic cylinder, in particular to a self-resetting single-acting hydraulic cylinder. Background technique [0002] A hydraulic cylinder is an actuator in a hydraulic system that converts hydraulic energy into mechanical energy for linear motion. If the movement of the hydraulic cylinder in both directions is achieved by hydraulic oil, such a hydraulic cylinder is called a double-acting hydraulic cylinder. If the movement of a hydraulic cylinder in one direction is achieved by its own weight or external force, this type of hydraulic cylinder is called a single-acting hydraulic cylinder. type hydraulic cylinder. The current single-acting hydraulic cylinder includes a cylinder bottom, a cylinder body, a piston, a piston rod and a cylinder head. The cylinder head extends into the cylinder body and connects with the piston. An oil chamber is formed between the piston and the cylinder bottom in the cylinder body....
