Working principle: in order to solve the problem that the boom shelf 6 can be reversed, the ship deck 1 is kept flat after the boom shelf 6 is disassembled, stacking, loading and unloading of containers are not affected, and a groove base body is arranged below the ship deck 1.
The groove base body consists of a rectangular base bottom plate 4, a front rectangular base inclined plate 5, a rear rectangular base inclined plate 5 and a left base side plate 3 and a right base side plate 3, and forms a funnel-shaped box-shaped structure for placing a suspension arm shelf 6. The arrangement of the front and rear strip-shaped base inclined plates 5 facilitates the left and right normal flat placement of the boom shelf 6, and the two sides of the base side plate 3 are provided with three bolt holes, so that the bottom of the boom shelf 6 is conveniently connected with the base side plate 3 through bolts. The elongated open slot 2 of the vessel deck 1 facilitates the insertion and rotation of the boom shelf 6 bottom structure.
When the boom shelf 6 is required to be placed down towards the stern, the square bolts 8 on the base side plates 3 on the two sides and the round bolts 9 in the bow direction are pulled out, and the boom structure 13 of the crane 12 is used for hooking the lifting eyes at the side end of the boom shelf 6, so that the slow rotation and flat placement of the boom shelf 6 towards the stern direction can be completed. When the boom shelf 6 needs to be put down towards the bow direction, the operation is similar to the process, and only the round bolt 9 in the stern direction needs to be pulled out.
When the shelf is required to be normally used, the hanging eye at the side end of the hanging arm shelf 6 is hooked by the hanging arm structure 13 of the crane 12, the hanging arm shelf 6 is slowly hung to be vertical by taking the joint of the round bolt 9 as the center of a circle, then the two remaining bolt holes are fixed by the round bolt 9 and the square bolt 8, and the two sides of the bolt holes are firmly jacked by the hydraulic cylinder, so that the hanging arm shelf 6 device is firmly fixed, and the hanging hook of the hanging arm structure 13 and the like are placed on the top of the hanging arm shelf.
When the boom shelf 6 is required to be lifted off, the whole boom shelf 6 can be lifted off only by pulling out all the bolts. Because the groove base body is positioned below the ship deck 1, after the boom shelf 6 is adjusted away, the cargo stacking of the ship deck 1 is not affected completely, and the container packing number on the ship deck 1 can be guaranteed to the greatest extent.
The inclined planes on two sides of the rotating seat 7 and the inclined angle between the boom shelf 6 are set to be the same structure as the inclined angles between the base bottom plate 4 and the base inclined plate 5, so that when the boom shelf 6 is placed to be horizontal, the inclined planes of the rotating seat 7 can be just attached to the base inclined plate 5 on the corresponding surface, and the purpose of supporting is achieved. The two sides of the bottom end of the rotating seat 7 are arranged to be of a round chamfer structure, the circle centers of the round chamfer and the circle centers of the round jacks are mutually overlapped, and therefore the purpose of the arrangement is that the bottom of the rotating seat 7 cannot cause interference to rotation during rotation. The base floor 4 is supported by the panel 10, and the panel 10 is also reinforced by the toggle plate 11, which is advantageous in improving the stability of the overall structure.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
