The invention discloses a bridge erecting crane auxiliary arm quick installation mechanism. The bridge erecting crane auxiliary arm quick installation mechanism comprises a main arm and an auxiliary arm. The end of the main arm is provided with a groove for mounting of the auxiliary arm. A traction motor is fixed to the auxiliary arm. A winding wheel is fixed to the outer side of an output shaft of the traction motor. A traction steel rope is wound around the outside of the winding wheel. Two convex blocks are symmetrically mounted outside the auxiliary arm. Abutting assemblies matched with the two convex blocks are symmetrically mounted outside the main arm. A fixed insertion rod is fixed to the end, inserted into the groove, of the auxiliary arm. The inner bottom of the groove is provided with an insertion groove matched with the fixed insertion rod. The outside of the end, far away from the auxiliary arm, of the fixed insertion rod is symmetrically provided with two limiting grooves. Opposite insertion assemblies matched with the two limiting grooves are symmetrically mounted outside the main arm. The bridge erecting crane auxiliary arm quick installation mechanism implements three-time fixation on the auxiliary arm inserted at the end of the main arm in a mechanical driving mode, saves time and labor, improves the opposite insertion installation efficiency, can also preventaccidental injuries to workers and is practical and reliable.
