Hatch cover rib plate assembling anti-toppling tool

The invention discloses a hatch cover rib plate assembling anti-toppling tool, which comprises a bottom plate. Ribs are fixedly installed at the top of the bottom plate, a first sliding block and a second sliding block are installed at the tops of the ribs in a sliding mode, a supporting rod is movably installed at the top of the side, close to the second sliding block, of a baffle, and the other end of the supporting rod and the top of the second sliding block are movably installed. The three bolts are detached, the first sliding block and the second sliding block are moved on the ribs, the baffle and the supporting rod are driven to be subjected to position replacement, the nuts are tightened at the other ends of the three bolts to limit the first sliding block and the second sliding block, and when the hatch cover needs to be obliquely placed, the connecting rod is detached, the position of the second sliding block in different first limiting holes is changed, and therefore, the length value between the fi
