Abstract

The invention discloses a split hydraulic damper that is easy to replace and maintain, comprising an oil cylinder, a piston rod, a piston, a first connecting piece and a second connecting piece. An annular seat is integrally formed at the bottom of the oil cylinder, and an inner side wall of the annular seat is integrally formed. There is an installation groove on the upper part, the installation groove does not completely penetrate the side wall of the oil cylinder, and there are four layers of installation grooves on the annular seat, and each layer is provided with eight equal intervals; An annular seat is arranged at the position and an installation groove is opened on the inner side wall of the annular seat, and a piston assembly is formed by a combination of a secondary piston, a support assembly, a first connecting plate and a second connecting plate in the slot of the installation groove, Therefore, through the action of the piston assembly, the excessive pressure inside the cylinder of the hydraulic damper at the initial stage of stress is unloaded, so that the change of the hydraulic pressure inside the hydraulic damper cylinder is more uniform, thereby improving its overall actual use effect.

Description

technical field [0001] The invention relates to the technical field of hydraulic dampers, in particular to a split hydraulic damper that is easy to replace and maintain. Background technique [0002] The hydraulic damper is a hydraulic feed speed control device that can freely adjust the cylinder feed speed within the desired range from low speed to high speed. There are two types of control methods: spring return type (RB type) and air return type (R-A type), which can be selected according to the application. The damper is a device that provides resistance to movement and consumes movement energy. The use of damping to absorb energy and absorb shock is not a new technology. Various dampers (or shock absorbers) have been used in aerospace, aviation, military, guns, automobiles and other industries to reduce vibration and energy. Since the 1970s, people have gradually transferred these technologies to structural engineering such as buildings, bridges, and railways, and thei...
