Setting method of staggered rotating body

The invention discloses a method for setting a staggered swivel, which comprises the following steps of: confirming the railway land width, the railway safety control distance and the swivel bridge width so as to set the length of a cantilever swivel; setting the length of the cantilever swivel, wherein the length of the cantilever swivel is confirmed by adopting the following method: the railway safety control distance + the railway land use width + the railway safety control distance + (the swivel bridge width/4) = the length of the cantilever swivel. By means of the framing staggered swivel design, the swivel cantilever structure can be reduced by B/4 in length and reduced by B/2 in width, so that the swivel tonnage can be reduced by at least half, the weight of the swivel is reduced by more than half, the swivel cantilever length and the swivel spherical hinge bearing tonnage are reduced, the safety risk of construction close to a business line is reduced, the construction working face is reduced, and the
