Description
Technical Field
The invention particularly relates to a grating cover hook device and a grating cover fixing method.
Background
The position of the vertical opening in the ship inspection channel cabin is provided with the grid cover, the grid cover is opened when personnel pass through the grid cover, the grid cover is closed after the personnel pass through the grid cover, and when the personnel need to pass through the grid cover for a long time, the grid cover can be in an opening state within a certain time. In the partially open position, the grid cover can be opened by 180 degrees and directly overturned on the deck, while in the position of the broadside or the cabin edge, the grid cover can be opened by less than 150 degrees or even a smaller angle, and under the condition, when the ship shakes under the influence of wind waves, the grid cover is extremely easy to fall down, so that the potential safety hazard is large. At present, a chain or a hinge type hook is commonly used for fixing a grid cover of a ship, but in the mode, when the ship shakes under the influence of wind and waves, the chain is easy to throw, paint on the surface of a peripheral structure is damaged, and if the ship is in an oil tank, the hidden danger of burning and explosion caused by electric sparks generated by friction exists.
In order to solve the technical problem, the Chinese patent application with the publication number of CN210704497U discloses a cargo oil tank grating cover opening state fixing device, wherein a railing upright post is hinged with a cargo oil tank grating cover through a pin shaft, and the fixing device comprises a base (1), a bolt (2), a butterfly nut (3) and a semi-waist-shaped eye plate (4); the base (1) is arranged on a railing column (5) of the cargo oil tank, the base (1) and the railing column (5) are arranged vertically, and the base (1) is positioned above the pin shaft (6); a bolt (2) is arranged on the base (1); a cargo oil tank grid cover (7) is provided with a semi-waist-shaped eye plate (4), and a semi-waist-shaped groove (8) is arranged on the semi-waist-shaped eye plate (4); the butterfly nut (3) is in threaded connection with the bolt (2). When the device is used, the butterfly nut is taken down, the grating cover is opened by rotating the grating cover through the pin shaft pivot, the bolt is sleeved by the semi-kidney-shaped eye plate on the grating cover, and the grating cover is fixed by screwing the butterfly nut. When the grid cover is closed, the butterfly nut is taken down from the bolt, so that the semi-waist-shaped eye plate is moved out of the bolt, and the grid cover is pivoted by the pin shaft to realize closing. The device can realize the grid cover and open the back fixed, prevents that the grid cover from rocking, and stability is good. Although this device can be better fixed grid cover, this fixing device because the restriction of railing post position, when fixed grid cover, the unable change of angle that the grid cover was opened, the flexibility is not enough, simultaneously, to opening the grid cover that the angle is different, needs to carry out fixing device's position design again.
