The invention provides a gate lifting process protection device and an overload detection method, and the device comprises a current sensor which is used for measuring the current of a winch motor; the motion state detector is used for detecting the motion state of the steel wire rope; the control unit is used for receiving an operation signal of the winch motor, a winch motor current signal measured by the current sensor and a steel wire rope movement signal detected by the movement state detector, and the control unit can output a control signal to cut off operation of the winch motor. When any one of the operation state of the winch motor, the current value of the winch motor and the motion state of the steel wire rope does not meet the set requirement, the control unit cuts off the operation of the winch motor, so that the situation of non-fault parking is avoided, meanwhile, actions can be performed in time, and whether the gate is in an overload state or not is accurately judged. 本申请提供一种闸门提升过程保护装置及过载检测方
