The invention discloses an automatic tripping type lifting tool for pipe busbars. The automatic tripping type lifting tool comprises at least one pair of lifting components, all the lifting components clamp the pipe busbars in a spaced mode, each lifting component comprises a lifting lug, a pair of connecting rods and a pair of holding rods, and every two corresponding holding rods are movably hinged in an intersected mode. Holding openings matched with the external arc surfaces of the pipe busbars are formed in the bottom ends of every two corresponding holding rods, and the tops of the every two corresponding holding rods are movably hinged to the bottom ends of the two corresponding connecting rods. The top ends of every two corresponding connecting rods are movably hinged to the lower portion of the corresponding lifting lug. When the lifting lugs are upward and drive the connecting rods and the holding rods to be folded from the transverse directions to the middles, the holding openings are contracted and hold the pipe busbars; and when the lifting lugs are downward and drive the connecting rods and the holding rods to be folded from the vertical directions to the middles, the holding openings are expanded and loosen the pipe busbars. Locking pieces for preventing the holding openings from being contracted after the holding openings are expanded and loosened are further installed on the holding rods and/or connecting rods. The automatic tripping type lifting tool for the pipe busbars has the advantages of being simple in structure, convenient to operate, wide in application range, low in construction cost and high in safety.
