The invention belongs to a detection device and particularly relates to a telescopic lifting hook drift angle detection device. The drift angle detection device comprises a support base. The support base is fixedly installed on a base plate of a trolley. An x-direction rotation shaft passes through the lower end of the support base, and is fixedly connected to an x-axis encoder. An encoder connecting piece is fixed to the x-direction rotation shaft. A y-direction rotation shaft passes through the encoder connecting piece, and is fixedly connected to a y-axis encoder and a balancing weight. A positioning steel wire passes through hollow telescopic positioning bars. The y-direction rotation shaft is connected to the first of the telescopic positioning bars, and the first telescopic positioning bar is connected to the second telescopic positioning bar connected to the third telescopic positioning bar. The third telescopic positioning bar and the steel wire are connected to a lifting hook movable pulley. The drift angle detection device is characterized in that: angle positioning of the telescopic positioning bars and the positioning steel wire in lifting and falling processes and a lifting hook swing process can be achieved by utilization of a simple mechanical principle, and the drift angle detection device is simple in structure, flexible in movement, free in lifting and falling, safe and reliable.
