Self-balancing hydraulic lifting supporting device and application thereof

Abstract

The invention discloses a self-balancing hydraulic lifting supporting device. The self-balancing hydraulic lifting supporting device comprises a plurality of hydraulic lifting mechanisms, an oil conveying pipeline and an oil pump; each hydraulic lifting mechanism comprises a hydraulic cylinder; each hydraulic cylinder communicates with the oil conveying pipeline; a hydraulic control one-way valveis arranged between each hydraulic cylinder and the oil conveying pipeline; when the oil pump supplies oil to the oil conveying pipeline, each hydraulic control one-way valve is conducted; when the oil pump stops supplying oil to the oil conveying pipeline, each hydraulic control one-way valve is closed; and when the oil pump withdraws oil in the oil conveying pipeline, each hydraulic control one-way valve is reversely conducted. When the self-balancing hydraulic lifting supporting device supports a motor home, the supporting height on the motor home by the four hydraulic lifting mechanisms still can maintain consistent, so that the condition that the motor home inclines by the inconsistent lifting height of the four lifting mechanisms by single control of the four lifting mechanisms is avoided.

Description

technical field [0001] The invention relates to a self-balancing hydraulic lifting support device. Background technique [0002] When the RV is parked, it is necessary to support the RV to make the RV stable. At present, the device for supporting the caravan generally includes four lifting mechanisms, and the four lifting mechanisms are respectively installed at the four corners of the bottom of the caravan. When the caravan is parked, the four lifting mechanisms are unfolded so that the four lifting mechanisms The support seat on the top is against the ground, so that the four lifting mechanisms can support the caravan, but the current lifting mechanism is generally controlled independently, that is to say, when the caravan is parked, the four lifting mechanisms need to be separately controlled. Lifting operation, in this way, it is difficult for the lifting heights of the four lifting mechanisms to be completely consistent. The lifting heights of the four lifting mechani...

At present, the device for supporting the caravan generally includes four lifting mechanisms, and the four lifting mechanisms are respectively installed at the four corners of the bottom of the caravan. When the caravan is parked, the four lifting mechanisms are unfolded so that the four lifting mechanisms The support seat on the top is against the ground, so that the four lifting mechanisms can support the caravan, but the current lifting mechanism is generally controlled independently, that is to say, when the caravan is parked, the four lifting mechanisms need to be separately controlled. Lifting operation, in this way, it is difficult for the lifting heights of the four lifting mechanisms to be completely consistent. The lifting heights of the four lifting mechanisms tend to be the same, and such adjustments may need to be made many times, which makes the operation more troublesome when the RV is parked
