Abstract: An intelligent vehicle capturing apparatus for a high-pier bridge includes: a double-layer metal protective net, support unit and actuation unit connected thereto. The protective net mounts to a high-pier bridge backside through the support unit. The actuation unit includes a hydraulic link mechanism connected to one end of the protective net. The hydraulic link mechanism unwinds the protective net to capture a vehicle. The apparatus stops a vehicle rushing off a high-pier bridge. Upon completion, a hydraulic system drives a third hydraulic cylinder in a support rod on the high-pier bridge backside driving a rolling shaft rotating, winding and placing a protective net on the high-pier bridge backside. The apparatus has a simple structure, is practical and easily used, useful on hazardous high-pier bridges protecting vehicle passengers and avoiding traffic accidents resulting from vehicles rushing out of the high-pier bridges.
