Because the size of the through hole incision of the rib plate is only 4-7mm larger than the thickness of the longitudinal web plate, the relative positions of the rib plate and the sectional plate frame in the pulling-in assembly process need to be accurately controlled in order to prevent the rib plate from being obliquely blocked or being plastically deformed in the pulling-in process of the rib plate so as to prevent the assembly from being completed. However, in the prior art, when the rib plate is pulled in and assembled, the rib plate is generally lifted by a crane, and a plurality of side-by-side windlass are used for slowly pulling in the rib plate along the longitudinal bone pulling-in direction.

6. A rib assembly method for a ship body rib pull-in device according to claim 1, comprising the steps of:
step one, adjusting the position of a pick-up mechanism: controlling the first travelling part to operate so as to move the pickup mechanism to an assembling starting position of the rib plate along the first direction, wherein the first direction is the length direction of the longitudinal rib; controlling the second travelling part to run so as to move the pick-up mechanism to the middle part of the rib plate along the second direction; controlling the lifting part to run so as to enable the pick-up mechanism to be close to the rib plate along the height direction;
step two, picking up rib plates: opening the variable magnetic assembly to enhance the magnetism of the magnetic attraction assembly so that the magnetic force generated by the variable magnetic assembly and the magnetic attraction assembly is greater than the gravity of the rib plate; increasing the current of the variable magnetic assembly to increase the magnetic attraction force with an improvement so as to adsorb and fix the rib plate;
step three, drawing in rib plates: controlling the lifting part to move so as to lift the picking mechanism, so that the height of the through hole of the rib plate corresponds to the longitudinal bone; controlling the second travelling part to operate
The taking mechanism translates in the second direction so as to align the through holes of the rib plates with the longitudinal bones;
controlling the first travelling part to operate so as to enable the pick-up mechanism to move along the first direction,
so as to sleeve the rib plate on the longitudinal bone.
