The invention discloses a suspension girder type forepoling bar device. The suspension girder type forepoling bar device is characterized by comprising fixing clamping plates, locking bolts, nuts, anI-shaped steel top beam, a forepoling bar, pins, fixing holes and adjusting holes, wherein clamping grooves of the two fixing clamping plates are clamped to the lower edge of the I-shaped steel top beam, and are fixed on the I-shaped steel top beam through the locking bolts and the nuts; and the forepoling bar penetrates through the inner grooves of the fixing clamping plates and is matched with the fixing holes in the fixing clamping plates through the adjusting holes in the front probe beam, and the forepoling bar is fixed through the pins. The suspension girder type forepoling bar has the characteristics of being safe and reliable in performance, convenient and rapid to install, capable of automatically adjusting the front, rear, left and right positions during mounting, suitable for advanced exploration temporary supporting during tunneling of a shed supporting roadway, and capable of being repeatedly used.
