Abstract
Description
Technical Field
[0001] This utility model belongs to the field of marine engineering technology and relates to a bow pier. Background Technology
[0002] When large semi-submersible vessels with high tonnage carrying capacity carry out emergency rescue loading, they often need to use bow blocks to support the vessels being rescued. However, the existing bow 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 bow pier to solve the problem of insufficient bearing capacity of existing bow piers.
[0004] In order to solve the above technical problems, the present invention provides a bow block, which includes: a first layer of timber (2), a second layer of timber (3), a wedge (4) and a pad (5). The bow block is installed below the bow of the vessel to be rescued (6) 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 sets of wedges (4) are arranged on the second-layer piers (3) and located directly above the first-layer piers (2). Two sets of pads (5) are arranged directly above the two sets of wedges (4). The wedges (4) are fixed together with nails, and then the wedges (4) and the pads (5) are fixed with nails.
[0006] This utility model provides a bow block, including: a first layer of timber (2), a second layer of timber (3), wedges (4) and pads (5). This utility model designs a bow block structure according to the load-bearing requirements and height of the bow of the vessel to be rescued (4), which not only provides stable support, but also minimizes damage to the vessel to be rescued (4). Attached Figure Description
[0007] Figure 1 This is a structural diagram of the bow pier 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 bow block for supporting the bow of the vessel to be rescued (6) and ensuring its stability after being positioned. The bow block is installed after the vessel to be rescued (6) has been loaded and positioned, completely removed from the water, and the semi-submersible deck is exposed above the water. The installation of the bow block must be completed before the semi-submersible vessel is put into transport.
[0010] This utility model provides a bow block, comprising: a first layer of timber (2), a second layer of timber (3), a wedge (4) and a pad (5), the bow block being installed below the bow of the vessel to be rescued (6) 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 sets of wedges (4) are arranged on the second-layer piers (3) and located directly above the first-layer piers (2). Two sets of pads (5) are arranged directly above the two sets of wedges (4). The wedges (4) are fixed together with nails, and then the wedges (4) and the pads (5) are fixed with nails.
[0012] Among them, the bottom of the bow is a first layer of timber (2) with a length of 2000mm, a width of 300mm and a height of 300mm. The two first layer timbers (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 timbers is 1400mm.
[0013] Among them, seven second-layer piers (3) are arranged parallel to the length of the semi-submersible vessel.
[0014] Two sets of wedges (4) are arranged on the second layer of piers (3) and located directly above the first layer of piers (2). The wedges (4) are 60×140×300×2000mm in size. By adjusting the contact position of the inclined surfaces of the wedges (4), one set of wedges (4) can meet the vertical support covering a height range of 200±10mm.
[0015] Two sets of wooden blocks (5) are arranged directly above two sets of wedges (4). The wooden blocks (5) are 1600mm long, 300mm wide, and 111-136mm high to accommodate the curved outer surface of the vessel (6) to be rescued.
[0016] After the padding (5) is set up, adjust the inclined contact part of a set of wedges (4) so that the padding (5) is in complete contact with the lower surface of the vessel (6) to be rescued.
[0017] Use nails to secure the wedges (4) together, and then nail together a set of wedges (4) and a set of pads (5). 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.
[0018] Furthermore, the bow piers are installed after the vessel to be rescued (6) has been loaded and positioned, completely removed from the water, and the semi-submersible deck has emerged from the water. The installation of the bow piers must be completed before the semi-submersible vessel is transported and sailed. The two bow piers are arranged below the bow axis of the vessel to be rescued (6) to support the bow of the vessel to be rescued (6).
[0019] Furthermore, since the bow block is relatively heavy, a forklift is used on the semi-submersible vessel to move the bow block to the predetermined position and fix it. Alternatively, a sliding track parallel to the width of the ship is set on the deck of the semi-submersible vessel. Before loading, the bow block is moved to the side of the semi-submersible vessel, away from the navigation route of the vessel to be rescued (6) entering the deck of the semi-submersible vessel. After the rescue vessel (6) is positioned, loaded, and floats up, the bow block is moved along the track to the predetermined position and fixed to support the vessel to be rescued (6).
[0020] This utility model provides a bow block, including: a first layer of timber (2), a second layer of timber (3), wedges (4) and pads (5). This utility model designs a bow block structure according to the load-bearing requirements and height of the bow of the vessel to be rescued (4), which not only provides stable support, but also minimizes damage to the vessel to be rescued (4).
[0021] 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.
