Abstract

The invention discloses a hydraulic cylinder lifting system of a vertical mechanism of a basic curing machine. The hydraulic cylinder lifting system comprises a large oil tank, an oil way, an oil tank, a displacement sensor, an intelligent electromagnetic valve, a hydraulic cylinder and a pilot valve, wherein an oil inlet of the oil tank is connected with the large oil tank, the large oil tank isconnected with the hydraulic cylinder through the intelligent electromagnetic valve, and the pilot valve is connected with a hydraulic control port of the intelligent electromagnetic valve. The hydraulic cylinder lifting system is characterized by further comprising a check valve, a four-way reversing valve and a throttle valve; and an oil outlet of the check valve is connected with the oil tank,an oil inlet of the check valve is connected with an oil outlet of the four-way reversing valve, an oil inlet of the four-way reversing valve is connected with an oil outlet of the throttle valve, anoil outlet of the throttle valve is connected to the oil way between the intelligent electromagnetic valve and an oil port of a rodless cavity of the hydraulic cylinder, a hydraulic control port of the four-way reversing valve is connected with the hydraulic control port of the intelligent electromagnetic valve, and a fourth oil port of the four-way reversing valve communicates with the oil tank.

Description

technical field [0001] The invention belongs to the technical field of lifting systems, and in particular relates to a hydraulic oil cylinder lifting system of a vertical mechanism of a foundation curing machine. Background technique [0002] Jack-up drilling platform, also known as pile-foot drilling platform, is the most widely used drilling platform at home and abroad. The jack-up platform includes platform mechanism, pile legs, lifting mechanism and living building. When the jack-up platform is operating , the legs extend to the bottom of the sea and stand on the seabed. The jack-up platform uses the legs to support the hull of the platform, and keeps the bottom of the platform mechanism away from the sea surface for a certain distance; when the jack-up platform is towed, the legs are retracted, and the platform mechanism in a floating state. [0003] There is a hydraulic lifting system in the prior art, specifically a hydraulic plug-type lifting system used in the lift...
