After the conventional flap grill is opened, it is fixed by a bolt or a hook. Due to the shaking of the ship in the process of sailing in wind and waves, it is easy to cause collision noise and deformation to the bolt or hook, and the opening and fixing of the flip grill requires two hands to operate, and it is stable to open with one hand. Turnable grille, the other hand hasp to fix the turnable grille, especially in places with up and down straight ladder passages, it is easy for people to fall down and be injured by collision when the ship is sailing, which has a high safety hazard

The invention discloses an auxiliary device for fixing a turnable grating of an upper channel and a lower channel of a ship. The auxiliary device comprises a connecting piece and a hasp piece. The connecting piece and the hasp piece are both of a plate-shaped structure. One end of the connecting piece is fixed on the bulkhead close to one side, provided with the hinge, of the turnable grating. Theconnecting piece is positioned at the lateral upper part of the turnable grating. A stop block is arranged at the lower end of the connecting piece. A fixing nut is arranged in the middle of the plate surface of the connecting piece. The hasp piece is freely connected with the connecting piece. A clamping groove is formed in the end, close to the second connecting hole, of the hasp piece, the clamping groove is matched with the fixing nut, a hasp hook is arranged at the other end of the hasp piece, the hasp hook is of a downward protruding structure, and an opening matched with the turnover grille in thickness is reserved between the hasp hook and the second connecting hole. The device is simple in structure, convenient to operate, easy to manufacture and capable of effectively avoiding collision and falling of people going up and down the passage in the ship navigation process.
Description
technical field [0001] The invention relates to the field of ship building and safety, in particular to an auxiliary device for fixing a turnable grille for upper and lower passages of a ship. Background technique [0002] The grille is welded by flat steel and twisted steel. Its main application is in rest platforms, walkways, ditch covers and step boards, etc. It is widely used in shipbuilding, petrochemical, electric power, tap water, sewage treatment, port terminals, municipal Engineering and other fields. The grille at the opening of the upper and lower passages is often installed with a single-sided hinge to make the grille turnable. After the conventional flap grill is opened, it is fixed by a bolt or a hook. Due to the shaking of the ship in the process of sailing in wind and waves, it is easy to cause collision noise and deformation to the bolt or hook, and the opening and fixing of the flip grill requires two hands to operate, and it is stable to open with one han...
