DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0031] See also Figures 1-3 , which is a schematic structural diagram of the ship deck auxiliary platform provided by the utility model.

[0032] The ship deck auxiliary platform provided by the utility model is hung on the side 10 of the hull, and can increase the area of ​​the deck surface 20.

[0033] As can be seen from the drawings, the ship deck auxiliary platform provided by the present invention comprises two components: a platform surface 100 and a plurality of main body supports 200 .

[0034] Among them, a number of main body supports 200 are fixedly arranged in sequence at the bottom of the platform surface 100;

[0035] The main support 200 includes an inclined diagonal support 210 and a vertical support 220. One end of the diagonal support 210 is connected to the bottom of the platform surface 100, and the other end is provided with a support plate 230 for abutting against the side of the hull 10. Both ends of the vertical support 220 are respectively connected to the bottom of the platform surface 100 and the diagonal support 210.

[0036] Furthermore, a plurality of connecting parts 110 are provided at one end of the platform surface 100 close to the deck, and connecting holes 111 are provided on the connecting parts 110, and connecting shafts 112 are passed through the connecting holes 111. A plurality of structural hanging points 300 corresponding to the connecting parts 110 are provided in sequence on the hull side 10 close to the deck, and the structural hanging points 300 are provided with mounting grooves 310 adapted to the connecting shafts 112. The auxiliary platform is connected to the hull by placing the connecting shafts 112 in the mounting grooves 310.

[0037] The auxiliary platform is connected to the structural hanging point 300 and the support plate 230 is against the side 10 of the main hull, wherein the structural hanging point 300 is responsible for bearing the vertical load of the auxiliary platform and the platform cargo and the lateral load outward from the side 10, and the support plate 230 bears the load inward from the side 10.

[0038] Compared with the prior art, the platform surface 100 and the main support 200 of the auxiliary platform provided by the utility model are fixed structures. If the auxiliary platform needs to be installed, it only needs to lift the platform surface 100 and hang it on the hanging point structure 300 of the side 10 to achieve installation, which is simple to operate.

[0039] Moreover, in this solution, a connecting part 110 is provided at one end of the platform surface 100. A connecting shaft 112 penetrates through the connecting part 110. Correspondingly, an installation groove 310 adapted to the connecting shaft 112 is provided on the side of the hull 10. By lifting the platform surface 100 and placing the connecting shaft 112 at one end of the platform surface 100 into the installation groove 310, the installation of the auxiliary platform on the hull can be realized. The overall structure is simple and the operation is convenient.

[0040] Specifically, in this solution, the platform surface 100 preferably adopts a plate-like structure, and a number of openings are provided thereon. The number of openings can reduce the weight while ensuring the structural strength of the platform surface 100.

[0041] Such as Figure 1 , Figure 2 , in order to further improve the convenience of installing the auxiliary platform, a number of lifting points 120 are provided on the top of the platform surface 100. By setting the lifting points 120, it is convenient for the ship crane to install or disassemble the auxiliary platform;

[0042] In this solution, the number and distribution positions of the lifting points 120 are not limited and can be determined according to actual needs. As an example, in this instance, it is preferably set to four lifting points 120, and the four lifting points 120 are symmetrically arranged at the four corners on the top of the platform surface 100.

[0043] Such as Figure 2 , to ensure the working safety of the auxiliary platform, a detachable safety fence 130 is provided on the top of the platform surface 100. In this way, when the staff works on the platform surface 100, they can avoid falling.

[0044] The platform surface 100 with such a structure and a number of main supports 200 cooperate to form the main body of this auxiliary platform.

[0045] In this instance, it is preferably to adopt two groups of main supports 200, and the two groups of main supports 200 are symmetrically arranged on both sides of the bottom of the platform surface 100.

[0046] The main support 200 is designed as a truss structure, including a diagonal brace 210 and a vertical brace 220;

[0047] The inclined diagonal brace 210 and the vertically arranged vertical brace 220 are connected to the bottom of the platform surface 100, and the three cooperate to form a right triangle framework;

[0048] Such as Figure 5 , when the auxiliary platform is idle, the diagonal brace 210 is used as a support surface to support on the deck. In order to ensure the safety of the platform when it is placed on the ship deck surface 20 when idle, anti-slip support points 211 are respectively provided at positions near the platform surface 110 and the support plate 230 at both ends of the diagonal brace 210;

[0049] The vertical strut 220 is used to enhance the structural strength of the platform.

[0050] In order to further improve the structural strength of the main support 200 and the structural strength of the entire auxiliary platform,

[0051] A number of reinforcing bars 240 are provided between adjacent main supports 200 and between the diagonal struts 210 and the vertical struts 220, and the number of reinforcing bars 240 is distributed staggeredly.

[0052] Furthermore, the support plate 230 is arranged at the end of the diagonal strut 210, which is used to abut against the ship's side 10 and bear the load;

[0053] In order to protect the paint surface outside the ship's side 10 of the ship, the support plate 230 is made of a nylon support plate that is resistant to seawater corrosion and has high strength.

[0054] The auxiliary platform with the above structure is connected to the structural hanging point 300 of the ship's side 10 through a number of connecting parts 110;

[0055] In this embodiment, it is preferably to use two connecting parts 110, and the two connecting parts 110 are symmetrically arranged on both sides of the end of the platform surface 100;

[0056] The connecting part 110 is an ear plate structure. By opening a connecting hole 111 on the connecting part 110, the connecting shaft 112 is penetrated and arranged in the connecting hole 111. By placing the connecting shaft 112 into the installation groove 310 in the structural hanging point 300, the connection between the auxiliary platform and the hull is realized.

[0057] The above connecting shaft 112 is preferably an axletree pin.

[0058] To ensure the installation convenience of the auxiliary platform, this solution utilizes the self-locking principle of mechanical design. The structural hanging point 300 is designed on the deck ship's side 10. Only through the connecting shaft 112 can the auxiliary platform be connected to the main hull. Under normal circumstances, the self-weight of the auxiliary platform plus the weight of the goods will cause the entire platform to bear the vertical load and the horizontal load towards the inside or outside. The structural design of the installation groove 310 can bear the horizontal load towards the inside of the auxiliary platform and the vertical load. The horizontal load towards the inside is jointly borne by the installation groove 310 and the diagonal strut 210. Due to the free rotation of the connecting shaft 112 under the influence of the self-weight of the auxiliary platform, the support plate 230 can be tightly attached to the outer plate of the main ship. The entire mechanical system is stable and reasonable.

[0059] Such as Figure 3 In this embodiment, two structural hanging points 300 are correspondingly provided for one connecting part 110, and the two structural hanging points 300 are respectively distributed on both sides of the connecting part 110.

[0060] Such as Figure 4, in order to further improve the security of the auxiliary platform plug-in, a safety lock 400 is provided at the structural hanging point 300 in this solution, and the connecting shaft 112 placed in the installation groove 310 is locked through the safety lock 400.

[0061] When the ship is operating in the sea, it will produce rolling and heaving motion states. If it encounters a sudden bad ocean environment, it will cause the ship's rolling angle to be too large or the heaving acceleration to be too large (this sea condition is a small probability event), and there will be an extreme situation where the connecting shaft 112 of the platform disengages from the installation groove 310. The reason for the existence of the safety lock 400 is to prevent this situation from occurring.

[0062] Furthermore, the safety lock 400 includes a first part 410 and a second part 420. The first part 410 is fixedly arranged on one side of the installation groove 310. One end of the second part 420 is movably connected to the other side of the installation groove 310. The other end of the second part 420 is provided with a mounting hole, and the first part 410 is provided with an opening adapted to the mounting hole. The second part 420 is arc-shaped. By rotating along the movable connection point and fixing the mounting hole and the opening through a fastener, the second part 420 cooperates with the installation groove 310 to be able to press the connecting shaft 112 placed in the installation groove 310 to limit the vertical movement of the connecting shaft 112.

[0063] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention.
