Description

Technical Field

[0001] The invention relates to the field of shipbuilding, and in particular to a transport device for 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.

[0003] The current transportation method is: the deck sections are transported from the workshop of Factory A to the dock, and the gantry crane is used to lift the deck sections one by one onto the barge, and the necessary fastening is performed on the deck sections. The barge transports them from Factory A to Factory B, and the gantry crane is used to lift the deck sections one by one onto the platform at the dock of Factory B. Therefore, in the existing transportation and lifting process, each time the deck sections are lifted from the barge to the dock platform, the gantry crane will be occupied once. Considering the large-scale transportation demand for car carrier deck sections, the original transportation method will occupy a large amount of dock gantry crane resources, which is very inefficient.

[0004] There are many deck sections that need to be transported, and they vary greatly. In order to be compatible with deck sections of different specifications, the loading area of ​​the transport device must be at least 22m*22m. This will result in a larger transport device, more materials, high production costs, heavy weight, and difficulty in lifting. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a transport device for deck sections in order to overcome the defects in the prior art of low efficiency of deck section transport, large consumables, heavy weight and difficulty in lifting of the transport device.

[0006] The present invention solves the above technical problems through the following technical solutions:

[0007] A transport device for deck segments, the transport device comprising a load-bearing part and a guardrail, the load-bearing part is in a grid shape, the load-bearing part comprises a plurality of beams arranged at staggered intervals, the plurality of beams are fixedly connected to form a frame structure for carrying the deck segments;

[0008] The guardrail is fixedly connected to the load-bearing portion, and the guardrail is continuously distributed around the transport device in the circumferential direction to prevent the deck segment from sliding away from the load-bearing portion during transportation;

[0009] The transport device is also provided with a plurality of hoisting parts, and the transport device is hoisted by the hoisting parts to transfer the deck segments.

[0010] In this solution, by making the load-bearing part a grid-like structure, a stable frame structure is provided to carry the deck segments. The main body of the load-bearing part is formed by beams, which reduces the weight of the transport device, reduces the materials required for making the load-bearing part, and increases the load-bearing capacity and stability during hoisting. The transport device is provided with a guardrail structure to prevent the deck segments from slipping away from the load-bearing part during transportation, thereby increasing the safety and reliability of transportation. The transport device is provided with a hoisting part, which facilitates hoisting and transportation. By placing multiple deck segments on the transport device and transporting them, the transportation efficiency of the deck segments is improved and hoisting is easy.

[0011] Preferably, the hoisting portion is a hoisting horse.

[0012] In this solution, the lifting part is a lifting horse, which is convenient for lifting the transport device.

[0013] Preferably, the lifting horses are distributed at intervals along the circumferential direction on the side walls of the transport device.

[0014] In this solution, by distributing the lifting horses at intervals along the circumference on the side wall of the transport device, a more flexible lifting position selection is provided, so that the transport device can meet the lifting requirements in different scenarios, and the flexibility of the lifting position and lifting operation is enhanced. The spacing of the lifting horses can make the load distribution during lifting more uniform, and improve the stability and carrying capacity of the transport device during lifting. The lifting horses are arranged on the side wall of the transport device so that the lifting horses do not occupy the loading area of ​​the transport device, and the wire rope can be prevented from interfering with the loaded deck section during lifting.

[0015] Preferably, the beam member includes a main beam, which includes a plurality of longitudinal beams and a plurality of transverse beams, the longitudinal beams are distributed in parallel and spaced apart along the length direction of the transport device, the transverse beams are distributed in parallel and spaced apart along the width direction of the transport device, and the longitudinal beams and the transverse beams are perpendicular to each other and fixedly connected.

[0016] In this solution, the beam is composed of multiple longitudinal and transverse beams. The distribution and composition of the beams form a stable skeleton structure, which provides more efficient load distribution and carrying capacity. Compared with the entire pallet-type transport load-bearing part, the skeleton structure of this solution reduces the weight of the overall transport device load-bearing part, saving material costs and lifting loads.

[0017] Preferably, the beam member includes an auxiliary beam, and the auxiliary beam includes a plurality of longitudinal auxiliary beams and a plurality of transverse auxiliary beams, the longitudinal auxiliary beams are parallel and spaced along the length direction of the transport device, the transverse auxiliary beams are parallel and spaced along the width direction of the transport device, the longitudinal auxiliary beams are spaced between two adjacent longitudinal beams, and the transverse auxiliary beams are spaced between two adjacent transverse beams;

[0018] The upper surface of the auxiliary beam and the upper surface of the main beam are kept flush in the vertical direction.

[0019] In this solution, the auxiliary beam is fixedly connected to the main beam, which optimizes the skeleton structure of the beam, enhances the stability and load-bearing capacity of the skeleton, and thus increases the load-bearing capacity and stability of the transport device. The upper surface of the auxiliary beam and the upper surface of the main beam are kept flush in the vertical direction, so that the surface of the bearing part is uniform and flat, which is convenient for the segmentation of the bearing deck and prevents tilting during placement.

[0020] Preferably, the auxiliary beam and the main beam are fixedly connected, a rib plate is provided at the connection between the auxiliary beam and the main beam, the rib plate is provided on the side wall of the auxiliary beam, and two ends of the rib plate are respectively fixedly connected to the auxiliary beam and the main beam.

[0021] In this solution, the auxiliary beam and the main beam are fixedly connected by rib plates, which serve as reinforcement ribs to enhance the connection strength between the main beam and the auxiliary beam, avoid stress concentration, and improve the durability of the structure.

[0022] Preferably, a protective net structure is arranged along the circumferential direction on a portion of the inner side of the bearing portion close to the edge, and the protective net structure is embedded in the gap between adjacent beam members.

[0023] In this solution, by arranging the protective net structure along the circumferential direction on the inner side of the load-bearing part near the edge, the hollow gaps around the transport device are blocked, which makes it easier for personnel to walk on the load-bearing part of the transport device and ensures their safety. The protective net structure increases the friction force, prevents the deck sections from sliding or moving sideways during transportation, and enhances the edge protection effect of the transport device.

[0024] Preferably, the guardrail includes upright posts and cross braces, a plurality of upright posts are continuously distributed around the transport device in the circumferential direction, and the cross braces are fixedly connected between adjacent upright posts.

[0025] In this solution, the guardrail is composed of columns and cross braces to form a continuous protective structure, which improves the strength and protection range of the guardrail and prevents the deck sections from escaping from the loading position and slipping off the transport device during transportation; the structural strength of the guardrail is increased by the cross braces.

[0026] Preferably, the spacing between adjacent columns is smaller than the minimum dimension of the deck segments, and the height of the columns is higher than the highest height of the stacked deck segments to prevent the deck segments from sliding off the load-bearing portion during transportation.

[0027] In this solution, by designing the spacing and height of the columns, the possibility of the deck sections being separated from the loading position and falling from the load-bearing part is reduced, the protective effect of the guardrail is enhanced, and the safety and reliability of transportation and loading are increased.

[0028] Preferably, the bearing portion is rectangular.

[0029] In this solution, the load-bearing part adopts a rectangular design, which optimizes the layout and space utilization when loading deck sections. The load-bearing parts of traditional designs or other shapes may have unreasonable layouts, poor adaptability to deck sections of different specifications, and low space utilization. The rectangular load-bearing part for transport loading can optimize the layout and improve space utilization.

[0030] The positive and progressive effects of the present invention are: a stable frame structure is provided through a load-bearing part with a grid structure to carry the deck segments. The main body of the load-bearing part is formed by beams, which reduces the weight of the transport device, reduces the materials required for making the load-bearing part, and increases the load-bearing capacity and stability during hoisting. The transport device is provided with a guardrail structure to prevent the deck segments from slipping away from the load-bearing part during transportation, thereby increasing the safety and reliability of transportation. The transport device is provided with a hoisting part, which facilitates hoisting and transportation. By placing and transporting multiple deck segments on the transport device, the transportation efficiency of the deck segments is improved and hoisting is easy. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0053] like Figure 1-Figure 5 As shown, the present embodiment provides a transport device 1 for deck segments, the transport device 1 comprises a load-bearing portion 2 and a guardrail 3, the load-bearing portion 2 is in a grid shape, the load-bearing portion 2 comprises a plurality of beams 20 arranged at staggered intervals, the plurality of beams 20 are fixedly connected to each other to form a frame structure for carrying the deck segments; the guardrail 3 is fixedly connected to the load-bearing portion 2, the guardrail 3 is continuously distributed around the transport device 1 along the circumferential direction to prevent the deck segments from slipping away from the load-bearing portion 2 during transportation; the transport device 1 is also provided with a plurality of hoisting portions 4, the transport device 1 is hoisted by the hoisting portions 4 to transfer the deck segments.

[0054] Among them, a stable frame structure is provided by the load-bearing part 2 with a grid structure to carry the deck segments. The beam 20 is used to form the main body of the load-bearing part 2, which reduces the weight of the transport device 1, reduces the materials required for making the load-bearing part 2, and increases the load-bearing capacity and stability during lifting. The transport device 1 is provided with a guardrail 3 structure to prevent the deck segments from slipping away from the load-bearing part 2 during transportation, thereby increasing the safety and reliability of transportation. The transport device 1 is provided with a lifting part 4, which facilitates lifting and transportation. By placing and transporting multiple deck segments on the transport device 1, the transportation efficiency of the deck segments is improved and it is easy to lift.

[0055] like Figure 3 As shown, in this embodiment, as an implementation of the hoisting part 4, the hoisting part 4 is a hoisting horse 40, which is convenient for hoisting the transport device 1. In other implementations, the operator can select or design a hoisting part 4 of other structures according to the hoisting equipment.

[0056] like Figure 1As shown, the lifting horses 40 are distributed at intervals along the circumference on the side wall of the transport device 1. In this embodiment, by distributing the lifting horses 40 at intervals along the circumference on the side wall of the transport device 1, a more flexible lifting position selection is provided, so that the transport device 1 can meet the lifting requirements in different scenarios, and the flexibility of the lifting position and lifting operation is enhanced. Distributing the lifting horses 40 at intervals can make the load-bearing load distribution during lifting more uniform, and improve the stability and carrying capacity of the transport device 1 during lifting. The lifting horses 40 are arranged on the side wall of the transport device 1, so that the lifting horses 40 do not occupy the loading area of ​​the transport device 1, and the wire rope can be prevented from interfering with the loaded deck sections during lifting.

[0057] like Figure 1 and Figure 2 As shown, the beam member 20 includes a main beam 201, and the main beam 201 includes a plurality of longitudinal beams and a plurality of transverse beams. The longitudinal beams are distributed in parallel and spaced apart along the length direction of the transport device 1, and the transverse beams are distributed in parallel and spaced apart along the width direction of the transport device 1. The longitudinal beams and the transverse beams are perpendicular to each other and fixedly connected.

[0058] Among them, the beam 201 is composed of multiple longitudinal beams and transverse beams. The distribution and composition of the beam 201 form a stable skeleton structure, providing more efficient load distribution and carrying capacity. Compared with the entire pallet-type transport load-bearing part 2, the skeleton structure of this scheme reduces the weight of the overall transport device 1 load-bearing part 2, saving material costs and lifting loads.

[0059] like Figure 1 and Figure 2 As shown, the beam member 20 includes an auxiliary beam 202, and the auxiliary beam 202 includes a plurality of longitudinal auxiliary beams and a plurality of transverse auxiliary beams. The longitudinal auxiliary beams are parallel and spaced along the length direction of the transport device 1, and the transverse auxiliary beams are parallel and spaced along the width direction of the transport device 1. The longitudinal auxiliary beams are spaced between two adjacent longitudinal beams, and the transverse auxiliary beams are spaced between two adjacent transverse beams.

[0060] like Figure 2 , Figure 4 and Figure 5 As shown, the upper surface of the auxiliary beam 202 and the upper surface of the main beam 201 are kept flush in the vertical direction. The auxiliary beam 202 is fixedly connected to the main beam 201, which optimizes the skeleton structure of the beam 20, enhances the stability and load-bearing capacity of the skeleton, and thus increases the load-bearing capacity and stability of the transport device 1. The upper surface of the auxiliary beam 202 and the upper surface of the main beam 201 are kept flush in the vertical direction, so that the surface of the bearing part 2 is uniform and flat, which is convenient for bearing the deck segment and prevents tilting when placed.

[0061] like Figure 5As shown, the auxiliary beam 202 is fixedly connected to the main beam 201, and a rib plate 7 is provided at the connection between the auxiliary beam 202 and the main beam 201. The rib plate 7 is provided on the side wall of the auxiliary beam 202, and the two ends of the rib plate 7 are respectively fixedly connected to the auxiliary beam 202 and the main beam 201. The auxiliary beam 202 and the main beam 201 are fixedly connected by the rib plate 7, which serves as a reinforcing rib, thereby enhancing the connection strength between the main beam 201 and the auxiliary beam 202, avoiding stress concentration, and improving the durability of the structure.

[0062] Among them, Figure 1 and Figure 3 As shown, triangular plates 5 are provided as reinforcing ribs at the intersection of the beam 201 and the intersection of the hanging horse 40 and the beam 201 to enhance the structural strength of the connection part.

[0063] Among them, Figure 4 and Figure 5 As shown, as a specific implementation between the main beam 201 and the main beam 201 and the auxiliary beam 202, seams are reserved at the welding places of the main beam 201 and the main beam 201 and the auxiliary beam 202 for welding. A rib plate 7 is arranged at the vacant place where the auxiliary beam 202 and the main beam 201 are connected to enhance the connection strength and avoid stress concentration.

[0064] like Figure 1 As shown, a protective net structure 8 is arranged along the circumferential direction on the inner side of the load-bearing part 2 near the edge, and the protective net structure 8 is embedded in the gap between adjacent beams 20. By arranging the protective net structure 8 along the circumferential direction on the inner side of the load-bearing part 2 near the edge, the hollow gap around the transport device 1 is blocked, which facilitates personnel to walk on the load-bearing part 2 of the transport device 1 and ensures their operation safety. The protective net structure 8 increases the friction force, prevents the deck sections from sliding or moving sideways during transportation, and enhances the edge protection effect of the transport device 1.

[0065] like Figure 1 As shown in the figure, as an implementation of the protective net structure 8, the protective net structure 8 in this embodiment specifically includes a protective net 82 and an angle steel 81, and the angle steel 81 is staggered and vertically distributed below the protective net 82, and serves as a load-bearing member to increase the strength of the protective net structure 8. In other implementations, the operator can set the specific form of the protective net structure 8 as needed or directly use a plate to replace the protective net structure 8, which can also make it easier for people to walk outside the bearing part 2.

[0066] like Figure 2As shown, the guardrail 3 includes columns 31 and cross braces 32. A plurality of columns 31 are continuously distributed around the transport device 1 along the circumferential direction, and cross braces 32 are fixedly connected between adjacent columns 31. The guardrail 3 is composed of columns 31 and cross braces 32 to form a continuous protection structure, which improves the strength and protection range of the guardrail 3 and prevents the deck segments from being separated from the loading position and slipping off the transport device 1 during transportation; the cross braces 32 increase the structural strength of the guardrail 3. In other embodiments, the operator can set other structures or shapes of the guardrail 3 as needed.

[0067] The spacing between adjacent columns 31 is smaller than the minimum size of the deck segment, and the height of the columns 31 is higher than the highest height of the stacked deck segments, so as to prevent the deck segments from slipping away from the load-bearing portion 2 during transportation. As a specific implementation of the guardrail 3, by designing the spacing and height of the columns 31, the possibility of the deck segment escaping from the loading position and falling from the load-bearing portion 2 is reduced, the protective effect of the guardrail 3 is enhanced, and the safety and reliability of transportation and loading are increased. In the specific implementation process, the spacing, specifications and height design of the columns 31 of the guardrail 3 can be determined by those skilled in the art as needed.

[0068] like Figure 1 and Figure 2 As shown in the figure, as a specific embodiment of the load-bearing part 2, the load-bearing part 2 is rectangular. The rectangular shape optimizes the layout and space utilization when loading the deck segment. The load-bearing part 2 of the traditional design or other shapes may have unreasonable layout, poor adaptability to deck segments of different specifications, and low space utilization. The use of a rectangular load-bearing part 2 for transport loading can optimize the layout and improve space utilization.

[0069] In this embodiment, the load-bearing portion 2 is a square grid structure. In other embodiments, those skilled in the art can determine the specific shape of the load-bearing portion 2 as needed, and other shapes including circular, arc, triangle, etc. can be adopted. The square is a preferred embodiment, and the smallest possible specification design can be adopted under the premise of adapting to deck sections of different shapes and specifications, saving materials of the transport device 1.
