Asphalt oil discharge tank over-limit alarm transport vehicle lifting system

The invention relates to the technical field of asphalt material conveying, in particular to a lifting system of an asphalt unloading tank over-limit alarm transport vehicle. The detection device is arranged in the oil discharge tank and is used for detecting the asphalt liquid level in the oil discharge tank; the unloading platform is arranged on one side of the oil unloading groove so that the transport vehicle can stop, the end, away from the oil unloading groove, of the unloading platform is hinged to the base, and the other end of the unloading platform is driven by a lifting system; and the controller is in communication connection with the lifting system and the detection device so as to send a driving instruction to the lifting system based on the detection data. The height of the liquid level in the oil discharge tank is detected, when the liquid level exceeds the limit, the asphalt transport vehicle is lifted, oil discharge is stopped, and hot asphalt is prevented from overflowing out of the oil dis
