| description | The utility model discloses a hose explosion falling prevention design for an assembled lifting oil cylinder. The hydraulic system comprises a first lifting oil cylinder, a second lifting oil cylinder, a reversing valve group assembly, a hydraulic oil source and a hydraulic oil tank, a first anti-pipeline-explosion valve and a second anti-pipeline-explosion valve are rigidly installed on an A/B oil port of the first lifting oil cylinder, and a third anti-pipeline-explosion valve and a fourth anti-pipeline-explosion valve are also rigidly installed on an A/B oil port of the second lifting oil cylinder. The hydraulic oil source and the hydraulic oil tank are connected with the reversing valve set assembly through pipelines. The first anti-pipeline-explosion valve and the third anti-pipeline-explosion valve are connected to the reversing valve set assembly through a first high-pressure hose and a third high-pressure hose which are connected in series, and the second anti-pipeline-explosion valve and the fourth a |
