Abstract

The invention provides a gas-liquid damping cylinder for vertical jacking. The gas-liquid damping cylinder comprises a central hydraulic cylinder, an outer-layer oil storage sleeve, a pneumatic cylinder cover and a hydraulically-controlled integrated cylinder seat. The hydraulically-controlled integrated cylinder seat is provided with two independent hydraulic channels communicated with a lower cavity of the central hydraulic cylinder and the outer-layer oil storage sleeve. Each of the hydraulic channels is provided with a one-way stop valve used for controlling liquid working media to flow from the lower cavity of the central hydraulic cylinder to the outer-layer oil storage sleeve. One of the hydraulic channels is further provided with a one-way throttle valve used for controlling the flow of the liquid working media from the lower cavity of the central hydraulic cylinder to the outer-layer oil storage sleeve when the one-way stop valve is opened. The gas-liquid damping cylinder has pneumatic convenience and hydraulic stability, operational speed can be adjusted optionally, halfway high-speed and low-speed instant changes can be realized, structure is simplified while the technical requirements such as slow lowering, rapid lowering and quick rising are met, and the gas-liquid damping cylinder has the advantages of pipeline integration, less proneness to oil leakage, small size, smooth movement, simplicity and convenience in operation, and the like.

Description

technical field [0001] The invention relates to the technical field of pneumatic-hydraulic integrated control, in particular to a gas-hydraulic damping cylinder for vertical jacking. Background technique [0002] As we all know, the working medium of the cylinder is compressed air. Its main feature is that the mechanical structure and its control system are simple, but its expansion and contraction speed and midway position are not easy to control, and are greatly affected by load changes. The working medium of the hydraulic cylinder is an incompressible liquid, which has the advantages of stable expansion and contraction speed, can stay at any time in the middle, large load capacity, and is not affected by load changes. However, the hydraulic control system is relatively complicated, and pipeline leakage is prone to occur during use. Wait for failure. The air-hydraulic damping cylinder combines the advantages of the air cylinder and the hydraulic cylinder ingeniously, and ...
