The invention relates to an intelligent pulley block applied to the hoisting machinery field, and belongs to the field of intelligent weight equipment. According to the device, strain gages are stuckon stress maximization parts of a pulley spindle, data is transmitted to a data processing center, and the deformation of the pulley spindle is monitored in real time; an axle load type sensor is arranged between pulley spindle supporting plates or hanging plates so as to be used for conveniently measuring and limiting the hoisting weight; a pulley revolution counting sensor is arranged above eachpulley of a pulley block; a lead wire of each pulley revolution counting sensor is connected with a junction box through a hollow rod; a data remote transmitter is arranged in the junction box; wireless temperature measurement systems embedded onto static sleeve rings of bearings transmit temperature signals to a ground data processing center through a wireless way; and lead wires of noise detection heads arranged under bushes are led to a shaft end through drill holes in the pulley spindle so as to carry out noise data wireless transmission. Compared with a traditional pulley block, the intelligent pulley block provided by the invention has perception and internet-of-things remote monitoring functions, and has higher reliability and sensitivity.
