Description

Technical Field

[0001] The utility model relates to the technical field of shipbuilding, in particular to a double detachable grille unit for a large opening of a ship engine room. Background Art

[0002] As an outfitting part used in the ship's engine room area, the grid frame is mainly used for personnel to walk or to hang other pipe and electrical accessories upside down. There is a large area of ​​hollow area in the large opening of the engine room, and the ship's pipelines, circuits and other outfitting parts cannot be installed in sections. In addition, the installation of super-large grid frames cannot be accurately positioned due to the lack of stable support. Therefore, the on-site gantry crane needs to hook the super-large grid frame for a long time to wait for the welding process to be completed. This not only makes on-site construction difficult and delays production plans, but also brings many safety hazards.

[0003] In the engine room area of ​​a ship, the lifting port and the unit platform sometimes overlap. The two have a shared relationship, that is, the grid unit must meet the basic requirements for walking and meet the specified dimensions required for the lifting path. When lifting certain small objects, the entire detachable part needs to be removed, which is not only time-consuming and labor-intensive, but also increases safety risks. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a double detachable grille unit for a large opening of a ship's engine room, which can meet the lifting requirements under various conditions, greatly improve the work efficiency, and greatly improve the navigation safety of the ship.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A double detachable grille unit for a large opening in a ship engine room comprises a grille unit body, wherein the grille unit body comprises a detachable unit and a fixed unit, wherein the detachable unit is a unit overlapping with a lifting opening, wherein the surrounding side walls of the detachable unit are detachably connected to surrounding outer structures adjacent thereto, and wherein a detachable sub-unit is provided on the detachable unit, wherein the detachable sub-unit is a part of the detachable unit.

[0007] Furthermore, the detachable unit is detachably connected to surrounding outer structures adjacent thereto by means of bolts.

[0008] Furthermore, the surrounding side walls of the detachable subunit are detachably connected to its peripheral structure via bolts.

[0009] Furthermore, a plurality of supporting legs are provided at intervals on the four sides of the lower end surface of the detachable sub-unit, and the supporting legs are L-shaped angle steels. The outer wall of one side plate in the length direction of the L-shaped angle steel is fixedly connected to the lower end surface of the detachable sub-unit, and the other side plate is arranged perpendicular to the detachable sub-unit, and its length direction is parallel to the center of the surface of the detachable sub-unit.

[0010] Furthermore, the grille unit body includes a plurality of channel steels arranged in parallel at intervals and a plurality of angle steels arranged in parallel at intervals. The angle steels are vertically intersected and connected to the channel steels. The sizes of the channel steels and the angle steels are adapted to the large opening of the cabin. The spacing between two adjacent angle steels is 600mm~700mm.

[0011] Furthermore, the grid unit also includes ship pipes, cables and outfittings located at the same position as the grid unit body, and the ship pipes, cables and outfittings are fixed to the grid unit body.

[0012] Furthermore, the grille unit is fixedly connected to the hull structure through embedded parts arranged around the inner side of the large opening of the cabin.

[0013] The utility model discloses a double detachable grille unit for a large opening in a ship's engine room. The detachable unit is arranged so that when a lifting opening and a unit platform sometimes overlap each other in the ship's engine room area, the grating unit provided can meet the basic requirement of being walkable and the specified size required for the lifting path. The detachable sub-unit is arranged so that when lifting certain small objects, only the detachable sub-unit part needs to be removed, and the detachable unit does not need to be removed as a whole, thus saving time and effort and reducing safety risks. Support legs are arranged around the lower end surface of the detachable sub-unit to prevent the unit module from falling during the removal process and causing damage to personnel and equipment.

[0014] The embedded parts are arranged in advance around the large opening of the cabin for spot welding. The arrangement height needs to fit the lowest point of each side of the grid unit, and the number of embedded parts needs to be increased at the equipment placement and personnel operation position. After the grid unit is hoisted as a whole, it is first placed above the embedded parts, and the unit posture is continuously adjusted according to the construction drawing to reach the predetermined position, and finally the welding operation is carried out. Reasonable use of embedded parts can improve the efficiency of on-site hook use, avoid the need to hook the unit for a long time waiting for welding, and thus affect the subsequent lifting plan arrangement. Through this technological innovation, the process flow can be simplified, production efficiency can be improved, and a safe production environment can be created for personnel, providing technical guarantees.

[0015] Combining ship pipes, cables and outfitting parts into grid units in the inner field not only increases installation accuracy and reduces on-site construction intensity, but also advances the process and improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
