description The utility model discloses an excess load oil pressure protection device of drift, including oil hydraulic cylinder, oil groove, pedestal, oil pressure pump, first oil duct, second oil duct and third oil duct. Wherein the oil hydraulic cylinder sets up in the drift, and the oil groove sets up in the drift and is located the oil hydraulic cylinder below, and drift one side is equipped with a horizontal opening that communicates the oil groove, the pedestal sets up outside the drift and covers the opening, and the pedestal has one towards preceding, the back of open-ended and a top surface, the oil pressure pump sets up in the back of pedestal. Up exceeding the level gauge through the guide of the oil circuit with first oil duct elder generation, down getting into the hydraulic pump again, the height of consequently guaranteeing first oil duct can be higher than the fuel head of hydraulic oil in the oil groove all the time, therefore, the hydraulic pump still hydraulic oil of its power of accessible in with the oil groove take out, and when the hydraulic pump was separated by the pedestal, based on the principle of communicating pipe, the hydraulic oil in the oil groove can not spilt by first oil duct in a large number yet.
