Background
In recent years, with the continuous development of the truck-mounted crane industry and the improvement of the technical reserve of engineering machinery, the technology that the hydraulic cylinder drives the telescopic arm to realize the telescopic of the main machine structure according to the sequence becomes a trend. The extension and retraction of the straight arm type suspension arm refers to that all sections of the extension arms extend and retract according to a certain sequence according to the extension and retraction mode of the hydraulic cylinder, and due to the matching performance requirement of the host suspension arm and the host hoisting capacity, all the hydraulic cylinders of the host extend and retract sequentially according to the section size of the host extension arm from large to small, and the retraction sequence is that the suspension arms retract sequentially from small to large. In the prior art, sequential expansion and contraction are realized by adding a sequential valve at the bottom of an oil cylinder or a cylinder barrel joint seat through different opening pressures of the valve, or by mechanically controlling a stroke valve at the bottom of the cylinder. The sequential scaling is an important function required by the host, and the performance and reliability of the sequential scaling are increasingly demanding on users. If the out-of-order phenomenon occurs, irreversible loss may be brought to the user. Therefore, the sequential telescopic test of the telescopic oil cylinder with the sequential telescopic requirement is important before the factory shipment, but no device specially used for testing the telescopic oil cylinder with the sequential telescopic requirement exists in the market at present.
In the prior art, only a device for performing tests such as test operation, pressure test, leakage test and the like on a single oil cylinder is provided, and a device specially used for testing telescopic oil cylinders with sequential telescopic requirements is not provided.
