The invention provides a winch alarm device for mining. A measuring device comprises a velocity sensor, a current sensor, a velocity comparator, a current comparator, a logic circuit, a timer and an alarm, wherein the velocity sensor is connected with a rotating shaft of a motor in a winch, the current sensor is arranged in an excitation circuit of the motor in the winch, the velocity comparator is connected with the velocity sensor, the current comparator is connected with the current sensor, the velocity comparator and the current comparator are respectively connected with the logic circuit, the timer is connected with the logic circuit, and the alarm is connected with the timer. According to the winch alarm device for the mining, when a condition of heavy load unloading of the winch occurs, an alarm signal is generated to remind a worker operating the winch of taking corresponding measures, so that production efficiency is improved. Meanwhile, safety accidents are prevented from occurring, and guarantee is provided for safety production operation.
