Description

Technical Field

[0001] The invention relates to the field of shipbuilding, and in particular to a method for transporting deck sections. Background Art

[0002] At present, the demand for the construction of car carriers is increasing. Such ships have large hulls, usually with up to 10-14 decks. There are many deck sections, and about three-quarters of the entire ship (three out of four sections) are deck sections. In order to improve construction efficiency and shorten the construction period, the number of deck sections that need to be built off-site accounts for about 30% of the entire ship. The off-site construction process of deck sections means that the sections are built at Factory A, then transported to the dock of Factory B, and then hoisted to the predetermined location. There are three main transportation processes:

[0003] Process 1: Lifting from the platform to the barge at the A plant dock.

[0004] Process 2: Barge shipping, from Factory A to Factory B.

[0005] Process 3: Hoisting from the barge to the platform at the B plant dock.

[0006] The current transportation method is: the deck sections are transported from the workshop of Factory A to the dock, and the deck sections are lifted one by one onto the barge using a gantry crane. The deck sections are secured as necessary, and the barge transports them from Factory A to Factory B. At the dock of Factory B, the deck sections are lifted one by one onto the platform using a gantry crane.

[0007] The existing transportation methods have the following defects:

[0008] 1. The lifting process occupies a large number of dock gantry crane resources. Dock gantry cranes are extremely scarce resources in shipyards. In the existing transportation method, each time the deck section is lifted from the barge to the dock platform, it will be occupied once. Considering the large-scale transportation demand for car carrier deck sections in the future, the original transportation method is very inefficient and will occupy a large number of dock gantry crane resources.

[0009] 2. A large number of barge resources are occupied. The existing transportation method is to lift the deck sections one by one onto the barge deck at the A plant dock. If the deck sections are placed in only one layer, the amount of deck sections that can be transported by one barge is very limited. The transportation efficiency is poor. Summary of the invention

[0010] The technical problem to be solved by the present invention is to overcome the defects of low efficiency and small transportation volume of the transportation process of deck sections in the prior art, and to provide a transportation method for deck sections.

[0011] The present invention solves the above technical problems through the following technical solutions:

[0012] A method for transporting deck sections, the method comprising:

[0013] Step 1: Load multiple deck segments into a pallet, and stack the multiple deck segments;

[0014] Step 2: Fixing the stacked deck segments to prevent the deck segments from moving away from their original positions;

[0015] Step 3: Transporting and / or lifting the pallet together with the deck segments to the target location.

[0016] In this solution, the deck sections are transported by pallets, thereby increasing the number of deck sections that can be transported in a single hoisting. By stacking the deck sections, the placement space of the deck sections is saved, and the number of deck sections that can be transported in a single hoisting is increased. The deck sections are fixed to prevent the deck sections from slipping off the pallet. This solution increases the number of deck sections that can be transported in a single hoisting or transportation by transporting the sections by pallets and stacking them, thereby improving transportation efficiency.

[0017] Preferably, the step 1 specifically includes the following steps:

[0018] Step 101: Load the first deck segment into a pallet and place it on top of the pallet;

[0019] Step 102: Load the next deck segment into the pallet and place it on top of the previous deck segment;

[0020] Step 103: Repeat steps 101 and 102 until the plurality of deck segments to be transported are loaded into the pallet.

[0021] In this solution, multiple deck segments are loaded into a pallet in sequence and stacked from bottom to top, which saves the floor space of the deck segments, allows multiple deck segments to be accommodated in one pallet, and improves transportation efficiency.

[0022] Preferably, mats are provided between a plurality of said deck segments;

[0023] And / or, a mat is provided between the deck segment and the pallet.

[0024] In this solution, by providing a mat, the deck segments are made to abut against the mat rather than directly abutting against the deck segments or pallet below, thereby preventing scratches between the deck segments or between the deck segments and the pallet due to relative movement and friction, thereby preventing damage to the surface of the deck segments or the pallet.

[0025] Preferably, the mat is a wooden mat.

[0026] Preferably, the step 2 specifically includes:

[0027] A lashing hole is provided at at least one end of the deck segment, and adjacent deck segments are lashed in pairs through the lashing hole, so that a plurality of deck segments are fixedly connected;

[0028] The stacked multiple deck segments are integrally tied and fixed to the pallet.

[0029] In this solution, by opening a lashing hole at one end of the deck segment, adjacent deck segments can be lashed in pairs through the lashing hole, so that a plurality of deck segments are fixedly connected, thereby increasing the stability of the deck segment stacking during transportation and reducing the risk of the deck segment sliding or falling off on the pallet. By lashing and fixing a plurality of deck segments to the pallet as a whole, the deck segments are fixed on the pallet, thereby increasing the safety and stability during transportation.

[0030] Preferably, the step 3 specifically includes:

[0031] transporting and / or lifting the pallet together with the deck in sections to the dock;

[0032] Lifting the pallet together with the deck segments onto the deck of the barge;

[0033] securing the pallet together with the deck segments to the barge deck;

[0034] transporting the pallet and the deck segment to a dock near a target location by barge;

[0035] The pallet is released from the deck of the barge together with the deck segments, and the pallet is lifted and / or transported to a target location together with the deck segments.

[0036] Preferably, in step 100, a plurality of deck segments are loaded into a pallet so that the beams of the deck segments are correspondingly placed above the load-bearing beams of the pallet.

[0037] In this solution, the deck segment's beams are arranged just above the pallet's load-bearing beams, so that the main load-bearing parts of the deck segment and the pallet's main load-bearing parts are positioned correspondingly, allowing the weight of the deck segment to be more stably transferred to the pallet, thereby increasing the stability and load-bearing performance of the overall structure.

[0038] Preferably, the step of fixing the pallet together with the deck segment to the barge deck specifically further comprises:

[0039] A plurality of fixing members are arranged along the outer circumference of the pallet, and two ends of the fixing members are fixedly connected to the pallet and the barge deck respectively.

[0040] In this solution, multiple fixings are arranged on the outer periphery of the pallet to fix the pallet on the barge deck, so that the deck segment and the pallet are fixedly connected to the barge deck, preventing the pallet and the barge deck from moving relative to each other and thus leaving the loading position during the barge transportation, thereby increasing the reliability of the transportation method. The fixed connection using fixings eliminates the need to directly weld and fix the deck segment, thus reducing damage to the deck segment and improving efficiency.

[0041] Preferably, in the step of providing a plurality of fixing members along the periphery of the pallet, wherein both ends of the fixing members are respectively fixedly connected to the pallet and the barge deck,

[0042] The fixing member has at least two extension parts with the same length, and the extension parts are symmetrically distributed at the ends of the fixing member.

[0043] In this solution, by making the fixing member have two extensions of the same length and symmetrically distributed at the ends of the fixing member, the operator can weld the extension at one end of the fixing member to the pallet and the other end to the barge deck when fixing the pallet through the fixing member, so as to facilitate the fixed connection between the pallet and the barge deck.

[0044] Preferably, in the step of providing a plurality of fixing members along the periphery of the pallet, wherein both ends of the fixing members are respectively fixedly connected to the pallet and the barge deck,

[0045] The outer side wall of the tray is provided with a plurality of connection holes, and each of the extension parts is provided with a fixing hole;

[0046] welding one of the extensions of the fixing member to the barge deck;

[0047] The other extension of the fixing member is bolted to the pallet through the fixing hole and the connecting hole, so that the deck segment together with the pallet are fixed to the barge deck.

[0048] In this solution, a connection hole is provided on the outer side wall of the pallet so that the fixing hole provided on the extension part can be bolted to the connection hole, thereby facilitating the fixing of the deck segment together with the pallet on the barge deck, and reducing the parts that need to be welded. When it is necessary to release the extension part of the other end of the fixing piece, a part of the extension part will be cut and lost. However, since the extension parts on the fixing piece all have fixing holes and the extension parts are symmetrically distributed, the next time the fixing piece is used, the welded end and the bolted end can be swapped to avoid the problem of the extension part length being affected by the cutting loss when releasing the welding fixation, and the difficulty in matching the fixing height. The number of uses of the fixing piece is increased, and the consumables cost of the transportation method is reduced.

[0049] A transport assembly comprises the pallet as described above and the deck segment, wherein the deck segment is placed above the pallet.

[0050] The positive and progressive effects of the present invention are: by transporting the deck segments by pallet, the deck segments on the pallet can be transferred by hoisting the pallet, thereby increasing the number of deck segments that can be transported in a single hoisting. By stacking the deck segments, the placement space of the deck segments is saved, and the number of deck segments that can be transported in a single hoisting is increased. The deck segments are fixed to prevent the deck segments from slipping off the pallet. The present solution increases the number of deck segments that can be hoisted or transported in a single hoisting or transportation by transporting the pallet and the stacked segments, thereby improving the transportation efficiency.

[0074] The present invention is further described below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

[0075] like Figure 1-Figure 8 As shown, this embodiment provides a method for transporting a deck segment 2, the method comprising:

[0076] S1: Loading a plurality of deck segments 2 into a pallet 1, and stacking the plurality of deck segments 2;

[0077] S2: Fixing the stacked deck segments 2 to prevent the deck segments 2 from being dislocated from their original positions;

[0078] S3: Transport and / or lift the pallet 1 together with the deck segment 2 to the target location.

[0079] In this embodiment, the deck segments 2 are transported by using a pallet 1, thereby increasing the number of deck segments 2 that can be hoisted or transported at a time. By stacking the deck segments 2, the placement space of the deck segments 2 is saved, and the number of deck segments 2 that can be transported at a time using the pallet 1 is increased. The deck segments 2 are fixed to prevent the deck segments 2 from slipping off the pallet 1. This solution increases the number of deck segments 2 that can be hoisted or transported at a time through the pallet 1 and the stacked segment transportation method, thereby improving transportation efficiency.

[0080] like Figure 2-Figure 3 As shown, as a specific embodiment of the pallet 1, the pallet 1 in this embodiment is a rectangular grid structure composed of beams 12 staggered vertically and horizontally. Through the arrangement of the grid structure, a stable frame structure is provided to carry the deck segment 2. The beams 12 are used to form the main body of the load-bearing part, which reduces the weight of the transportation device, reduces the materials required for making the load-bearing part, and increases the load-bearing capacity and stability during lifting. The pallet 1 is provided with a lifting part 11 around it for lifting the pallet 1. The pallet also has a guardrail 13, which is distributed circumferentially on the peripheral side of the pallet 1 to prevent the deck segment 2 from slipping during transportation.

[0081] In other embodiments, the pallet 1 may also be in other shapes including circular, elliptical, and arc-shaped, and may also carry multiple deck segments 2 for lifting and / or transportation, thereby increasing transportation efficiency. Those skilled in the art may design or adopt pallets 1 of other structures as needed.

[0082] like Figure 4 As shown, in this embodiment, the transportation and lifting in S3 include but are not limited to transporting the pallet 1 loaded on the deck segment 2 to the dock, lifting the pallet 1 to the barge deck 4, lifting the pallet 1 from the barge deck 4 to the dock, and lifting or transporting the pallet 1 to the target location. Figure 4 As shown, the hoisting part 11 is connected by a sling 8 to hoist the pallet 1. As an implementation of land transportation, the pallet 1 can be placed on a power head 3 or a flatbed transporter and transported to or from the dock. In other implementations, the operator can select a specific transportation method and route, as well as a transportation order as needed.

[0083] Among them, S1 specifically includes the following steps:

[0084] S101: Load the first deck segment 2 into the pallet 1 and place it on the pallet 1;

[0085] S102: Load the next deck segment 2 into the pallet 1 and place it above the previous deck segment 2;

[0086] S103: Repeat S101-S102 until the multiple deck segments 2 to be transported are loaded into the pallet 1.

[0087] like Figure 5-Figure 6 As shown, in this embodiment, multiple deck segments 2 are loaded into the pallet 1 in sequence and are stacked from bottom to top, thereby saving the floor space occupied by the deck segments 2, allowing multiple deck segments 2 to be accommodated in one pallet 1, thereby improving transportation efficiency.

[0088] like Figure 6 As shown, mats 5 are provided between the plurality of deck sections 2;

[0089] The pallet 1 in this embodiment is a grid-like structure, and it is not easy to set the mat 5 on the beam 12 of the pallet 1. In this embodiment, by setting the mat 5, the deck segment 2 is abutted against the mat 5, rather than directly abutting against the deck segment 2 or the pallet 1 below, thereby preventing scratches between the deck segments 2 or between the deck segment 2 and the pallet 1 due to relative movement and friction, thereby preventing damage to the surface of the deck segment 2 or the pallet 1. In other embodiments, the mat 5 can also be set between the deck segment 2 and the pallet 1.

[0090] like Figure 3As shown, when transporting the pallet 1, a mat 5 can be arranged between the pallet 1 and the power head 3 to serve as a load-bearing buffer to reduce damage caused by friction.

[0091] As an implementation method of the pad 5, the pad 5 in this embodiment is made of wood. In other implementation methods, other pad 5 materials including carbon fiber composite materials, PVC foam boards, etc. can also be used, all of which can bear the weight and prevent direct friction between steels to cause scratches and damage.

[0092] like Figure 6 As shown, S2 specifically includes:

[0093] A lashing hole (not shown in the figure) is opened at at least one end of the deck segment 2, and adjacent deck segments 2 are lashed together in pairs through the lashing hole to fix the plurality of deck segments 2 together;

[0094] The stacked multiple deck sections 2 are tied and fixed to the pallet 1 as a whole.

[0095] In this embodiment, by providing a lashing hole at one end of the deck segment 2, adjacent deck segments 2 can be lashed in pairs through the lashing hole, so that multiple deck segments 2 are fixedly connected, thereby increasing the stability of the stacking of the deck segments 2 during transportation and reducing the risk of the deck segments 2 slipping or falling off on the pallet 1. By lashing and fixing multiple deck segments 2 to the pallet 1 as a whole, the deck segments 2 are fixed on the pallet 1, thereby increasing the safety and stability during transportation.

[0096] like Figure 5-Figure 6 As shown, S3 specifically includes:

[0097] Transporting and / or lifting the pallet 1 together with the deck section 2 to the dock;

[0098] Lift the pallet 1 together with the deck section 2 onto the barge deck 4;

[0099] Fixing the pallet 1 together with the deck section 2 to the barge deck 4;

[0100] transporting the pallet 1 and the deck section 2 to a dock near a target location by a barge;

[0101] The pallet 1 together with the deck segment 2 is released from the barge deck 4 and the pallet 1 together with the deck segment 2 is lifted and / or transported to the target location.

[0102] In S100 , a plurality of deck segments 2 are loaded into the pallet 1 , so that the beams (not shown in the figure) of the deck segments 2 are correspondingly placed above the load-bearing beams of the pallet 1 .

[0103] In this embodiment, the main beam of the deck segment 2 is arranged just above the load-bearing beam of the pallet 1, so that the main load-bearing parts of the deck segment 2 and the main load-bearing parts of the pallet 1 are positioned correspondingly, so that the weight of the deck segment 2 is more stably transferred to the pallet 1, thereby increasing the stability and load-bearing performance of the overall structure.

[0104] The step of fixing the pallet 1 together with the deck segment 2 on the barge deck 4 specifically includes:

[0105] A plurality of fixing members 7 are arranged along the outer circumference of the pallet 1 , and two ends of the fixing members 7 are fixedly connected to the pallet 1 and the barge deck 4 respectively.

[0106] In this embodiment, a plurality of fixing members 7 are provided on the outer periphery of the pallet 1 so that the pallet 1 is fixed on the barge deck 4, so that the deck segment 2 together with the pallet 1 is fixedly connected to the barge deck 4, thereby preventing the pallet 1 and the barge deck 4 from moving relative to each other and thus leaving the loading position during the barge transportation, thereby increasing the reliability of the transportation method. The fixing members 7 are used for fixed connection, and there is no need to directly weld and fix the deck segment 2, thereby reducing damage to the deck segment 2 and improving efficiency.

[0107] like Figure 7 One of the fixed connection embodiments shown uses channel steel 6, which is installed around the pallet 1 and welded to the beam 12 of the pallet 1 and the barge deck 4, respectively, so that the pallet 1 and the deck segment 2 are fixed to the barge deck 4. This connection method also does not require direct welding and fixing of the deck segment 2, reducing damage to the deck segment 2.

[0108] like Figure 8 As shown, another specific embodiment of the fixing member 7 is provided, that is, in the step of arranging a plurality of fixing members 7 along the periphery of the pallet 1, and fixing members 7 at both ends thereof are respectively fixedly connected to the pallet 1 and the barge deck 4,

[0109] The fixing member 7 has at least two extensions 72 of the same length, and the extensions 72 are symmetrically distributed at the ends of the fixing member 7. By making the fixing member 7 have two extensions 72 of the same length and symmetrically distributed at the ends of the fixing member 7, the operator can weld the extension 72 at one end of the fixing member 7 to the pallet 1 and weld the other end to the barge deck 4 when fixing the pallet 1 through the fixing member 7. This facilitates the fixed connection of the pallet 1 and the barge deck 4.

[0110] like Figure 8 As shown, in the step of providing a plurality of fixing members 7 along the periphery of the pallet 1, wherein both ends of the fixing members 7 are respectively fixedly connected to the pallet 1 and the barge deck 4,

[0111] The outer side wall of the tray 1 is provided with a connection hole 17, and each extension portion 72 is provided with a fixing hole 71;

[0112] Welding one of the extensions 72 of the fixing member 7 to the barge deck 4;

[0113] Another extension 72 of the fixing member 7 is bolted to the pallet 1 through the fixing hole 71 and the connecting hole 17 , so that the deck segment 2 together with the pallet 1 are fixed to the barge deck 4 .

[0114] In this solution, a connection hole 17 is provided on the outer side wall of the pallet 1 so that the fixing hole 71 provided on the extension 72 can be bolted to the connection hole 17, thereby facilitating the fixing of the deck segment 2 together with the pallet 1 on the barge deck 4, and reducing the parts that need to be welded. When it is necessary to release the extension 72 at the other end of the fixing member 7, a part of the extension 72 will be cut and lost. However, since the extensions 72 on the fixing member 7 all have fixing holes 71, and the extensions 72 are symmetrically distributed, the next time the fixing member 7 is used, the welded end and the bolted end can be swapped to avoid the problem of the length of the extension 72 being affected by the cutting loss when releasing the welding fixation, and the difficulty in matching the fixing height. Compared with the implementation method of using the channel steel 6, the number of uses of the fixing member 7 is increased, and the consumables cost of the transportation method is reduced.

[0115] During the specific implementation process, those skilled in the art can design and adjust the shape, quantity and arrangement of the fixing members 7 as needed.

[0116] A transport assembly comprises a pallet 1 and a deck segment 2 as described above, wherein the deck segment 2 is placed above the pallet 1.

[0117] In the description of the present invention, it is necessary to understand that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. indicate the orientation or positional relationship of the device or element in normal use, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation at any time, and therefore cannot be understood as a limitation of the present invention in this regard.

[0118] Although the specific embodiments of the present invention are described above, it should be understood by those skilled in the art that this is only for illustration and the protection scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
