A hydraulic cylinder based on pressure relief and force reduction

Abstract

The invention discloses a hydraulic oil cylinder based on decompression and force reduction, and belongs to the field of hydraulic equipment. The hydraulic oil cylinder based on decompression and force reduction comprises a hydraulic oil cylinder body, wherein an oil storage chamber is dug in the hydraulic oil cylinder body; a telescopic port is dug in the right end of the hydraulic oil cylinder body and communicates with an oil storage chamber; a piston is slidably connected into the oil storage chamber; through arranging a decompression piece, an inertia impact force between the piston and the hydraulic oil cylinder body when the piston moves to the maximum stroke can be reduced, so that the phenomenon that the hydraulic oil cylinder body is damaged under a long-time impact effect of thepiston is not easy to occur, and the working stability of a hydraulic system is further improved; and meanwhile, through the matched use between a fastening frame and an arc-shaped limiting plate, the piston rod stopped after moving to a certain position is positioned and clamped, so that when the phenomenon that a hydraulic oil pipe is damaged or the oil cylinder is poor in sealing performance in the use process of the hydraulic oil cylinder body occurs, the piston rod is not easy to fall back, and the use safety of the hydraulic oil cylinder body is improved.

Description

technical field [0001] The invention relates to the field of hydraulic equipment, in particular to a hydraulic oil cylinder based on pressure relief and force reduction. Background technique [0002] In the machinery industry, the hydraulic cylinder is an important part of power transmission, and the working environment is harsh, especially in the metallurgy, mining and shipping industries, which have high requirements for the operation of machinery and equipment. In the process of mechanical transmission, hydraulic cylinders In the harsh working environment of high pressure, impact and instability, hydraulic cylinders are widely used in the control process of industrial production. The hydraulic cylinder is the actuator in the hydraulic transmission system. It is an energy conversion device that converts hydraulic energy into mechanical energy. It is used to drive the working mechanism to perform linear reciprocating motion or reciprocating swing. Its transmission works smo...

AI Technical Summary

Problems solved by technology

[0005] In view of the problems existing in the prior art, the object of the present invention is to provide a hydraulic cylinder based on pressure relief and force reduction, which can reduce the inertia between the piston and the hydraulic cylinder body when the piston moves to the maximum stroke by setting the pressure relief member The impact force makes the hydraulic cylinder body less likely to be damaged under the long-term impact of the piston, thereby improving the stability of the hydraulic system. At the same time, through the cooperation between the fastening frame and the arc-shaped limit plate, the movement After stopping at a certain position, the piston rod is positioned and clamped, so that when the hydraulic oil pipe is damaged or the cylinder seal is poor during the use of the hydraulic cylinder body, the piston rod is not easy to fall back, which improves the safety of the hydraulic cylinder body.
