Abstract
Description
Technical Field
[0001] This utility model belongs to the field of shipbuilding engineering technology and relates to a stern block. Background Technology
[0002] When large semi-submersible vessels with high tonnage carrying capacity carry out emergency rescue loading, they often need to use stern blocks to support the stern of the vessel to be rescued. However, the existing stern blocks do not have sufficient load-bearing capacity to meet the requirements. Summary of the Invention
[0003] The purpose of this invention is to provide a stern pier to solve the problem of insufficient load-bearing capacity of existing stern piers.
[0004] In order to solve the above technical problems, the present invention provides a stern block, which includes: a first layer of block wood (2), a second layer of block wood (3), a third layer of block wood (4), wedge wood (5) and pad wood (6). The stern block is installed below the stern of the vessel to be rescued (7) and on the semi-submersible deck (1).
[0005] Two first-layer piers (2) are arranged parallel to each other on the deck (1) of the semi-submersible vessel along the width of the deck. Seven second-layer piers (3) are arranged parallel to each other on the first-layer piers (2) along the length of the semi-submersible vessel. Two third-layer piers (4) are arranged on the second-layer piers (3) and located directly above the first-layer piers (2). Two sets of wedges (5) are arranged on the third-layer piers (4). Two sets of pads (6) are arranged directly above the two sets of wedges (5). The wedges (5) are fixed together with nails, and then the wedges (5) and the pads (6) are fixed with nails.
[0006] This utility model provides a stern block, including: a first layer of wooden blocks (2), a second layer of wooden blocks (3), a third layer of wooden blocks (4), wedges (5) and pads (6). This utility model designs a stern block structure according to the load-bearing requirements and height of the stern of the vessel to be rescued (7), which not only provides stable support, but also minimizes damage to the vessel to be rescued (7). Attached Figure Description
[0007] Figure 1 This is a structural diagram of the stern support of this utility model. Detailed Implementation
[0008] To make the objectives, contents, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.
[0009] This utility model provides a stern support for the stern of a vessel to be rescued (7) to ensure stability after it is positioned. The stern support is installed after the vessel to be rescued (7) has been loaded and positioned, completely removed from the water, and the deck of the semi-submersible vessel is exposed above the water. The installation of the stern support must be completed before the semi-submersible vessel is put into transport and sailing.
[0010] This utility model provides a stern block, comprising: a first layer of wooden blocks (2), a second layer of wooden blocks (3), a third layer of wooden blocks (4), wedges (5) and pads (6), the stern block being installed below the stern of the vessel to be rescued (7) and on the semi-submersible deck (1).
[0011] Two first-layer piers (2) are arranged parallel to each other on the deck (1) of the semi-submersible vessel along the width of the deck. Seven second-layer piers (3) are arranged parallel to each other on the first-layer piers (2) along the length of the semi-submersible vessel. Two third-layer piers (4) are arranged on the second-layer piers (3) and located directly above the first-layer piers (2). Two sets of wedges (5) are arranged on the third-layer piers (4). Two sets of pads (6) are arranged directly above the two sets of wedges (5). The wedges (5) are fixed together with nails, and then the wedges (5) and the pads (6) are fixed with nails.
[0012] Among them, the bottom of the stern block is a first layer of block (2) with a length of 2000mm, a width of 300mm and a height of 300mm. The two first layer blocks (2) are arranged parallel to each other on the deck surface of the semi-submersible deck (1) along the width direction of the semi-submersible deck, and the center line distance between the two blocks is 1400mm.
[0013] Among them, seven second-layer piers (3) are arranged parallel to the length of the semi-submersible vessel.
[0014] Among them, the two third-layer studs (4) are 2000mm long, 300mm wide and 300mm high, and are arranged on the second-layer studs (3), directly above the first-layer studs (2);
[0015] Two sets of wedges (5) are arranged on the third layer of piers (4). The wedges (5) are 60×140×300×2000mm in size. By adjusting the contact position of the inclined surface of the wedges (5), one set of wedges (5) can meet the vertical support covering a height range of 200±10mm.
[0016] Two sets of pads (6) are arranged directly above two sets of wedges (5). The pads (6) are 1600mm long, 300mm wide, and 111-136mm high to accommodate the curved outer surface of the vessel (7) to be rescued.
[0017] After the padding (6) is set up, adjust the inclined contact part of a set of wedges (5) so that the padding (6) is in complete contact with the lower surface of the vessel to be rescued (7).
[0018] Secure the wedges (5) together with nails, and then secure one set of wedges (5) and one set of pads (6) with nails. For any remaining small gaps, drive in small wedges to ensure that all the wood is in complete contact and the force is evenly distributed.
[0019] Furthermore, the stern blocks are installed after the vessel to be rescued (7) has been loaded and positioned, completely removed from the water, and the semi-submersible vessel deck is exposed above the water. The installation of the stern blocks must be completed before the semi-submersible vessel is transported and sailed. The two stern blocks are arranged below the stern axis of the vessel to be rescued (7) to support the stern of the vessel to be rescued (7).
[0020] Furthermore, since the stern block is relatively heavy, a forklift is used on the semi-submersible vessel to move the stern block to the predetermined position and fix it. Alternatively, a sliding track parallel to the width of the vessel is set on the deck of the semi-submersible vessel. Before loading, the stern block is moved to the side of the semi-submersible vessel, away from the navigation route of the vessel to be rescued (7) entering the deck of the semi-submersible vessel. After the rescue vessel (7) is positioned, loaded, and floats up, the stern block is moved along the track to the predetermined position and fixed to support the vessel to be rescued (7).
[0021] This utility model provides a stern block, including: a first layer of wooden blocks (2), a second layer of wooden blocks (3), a third layer of wooden blocks (4), wedges (5) and pads (6). This utility model designs a stern block structure according to the load-bearing requirements and height of the stern of the vessel to be rescued (7), which not only provides stable support, but also minimizes damage to the vessel to be rescued (7).
[0022] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
