Description

Technology Field

[0001] The present invention relates to a support device for cargo tank manufacturing equipment. Background Technology

[0002] In the shipbuilding industry, which consists of design, construction, and delivery starting from a ship order, operational profitability throughout the process is crucial. One of the factors determining profitability is productivity in the shipbuilding method, and the shipbuilding industry is striving to improve this productivity.

[0003] In LNG cargo tanks manufactured in the shipbuilding industry, bonding equipment (e.g., secondary barrier bonding equipment) is attached to the wall and performs work while moving. The weight of the bonding equipment that can move along the wall (a weight that is difficult for a single worker to lift, e.g., 80 kg) places a burden on the worker when installed on the wall.

[0004] For the bonding equipment to travel along the wall, the plate-shaped guide on the side of the equipment must be inserted into the slit (groove) of the insulation panel; after positioning the equipment, the equipment is operated to insert the guide into the groove.

[0005] Therefore, the bonding equipment must be continuously maintained in place during the time spent setting up, operating, and running the equipment. In particular, improvements are needed for the upward-sloping or vertical sections, as workers must support the weight of the bonding equipment in difficult positions for installation.

[0006] In particular, the installation and removal of the bonding device are repeated more than 30 times a day. Each time, the bonding device must be lowered to the floor for preparation procedures, such as securing a drum wound with Triplex, a secondary barrier material, to the end of the device. Consequently, workers must repeatedly lift and lower the bonding device from head height to the floor, which causes difficulties such as musculoskeletal problems and requires improvement. The problem to be solved

[0007] The problem that the present invention aims to solve is to provide a support device for cargo tank manufacturing equipment that can easily handle cargo tank manufacturing equipment, such as bonding equipment.

[0008] The problems of the present invention are not limited to those mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the description below. means of solving the problem

[0009] One aspect of the support device for cargo tank manufacturing equipment according to the present invention for achieving the above objective includes a support unit that supports manufacturing equipment for manufacturing a cargo tank, and a multi-axis drive unit that rotates the support unit or moves it in an up-and-down direction.

[0010] The above multi-axis drive unit may include a first rotation module that rotates in a first rotation direction so that the support unit can tilt, and a lifting module whose length is adjusted in an up-and-down direction so that the level of the support unit changes.

[0011] The above multi-axis drive unit may include a second rotation module that is rotated so as to rotate radially on a planar view, the support unit.

[0012] It may further include a cushion unit that elastically supports the above support unit.

[0013] The present invention may further include a body unit to which the multi-axis drive unit is connected and which is equipped with a rotation module, and a support that supports the lower end of the manufacturing equipment while protruding outwardly from the body unit.

Specific details for implementing the invention

[0017] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings. The advantages and features of the present invention, and the methods for achieving them, will become clear by referring to the embodiments described below in detail together with the attached drawings. However, the present invention is not limited to the embodiments disclosed below but can be implemented in various different forms. These embodiments are provided merely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims. Throughout the specification, the same reference numerals refer to the same components.

[0018] FIG. 1 is a drawing illustrating a ship equipped with a storage tank to explain a support device for cargo tank manufacturing equipment according to some embodiment of the present invention, and FIG. 2 is a drawing illustrating a storage tank to explain a support device for cargo tank manufacturing equipment according to some embodiment of the present invention. In addition, FIG. 3 is a drawing illustrating a cross-section of a storage tank to explain a support device for cargo tank manufacturing equipment according to some embodiment of the present invention, and FIG. 4 is a drawing illustrating a state in which manufacturing equipment is provided in a storage tank to explain a support device for cargo tank manufacturing equipment according to some embodiment of the present invention.

[0019] Referring to FIGS. 1 to 4, the liquid cargo carrier (10) may be a vessel that carries liquid cargo such as LNG or LPG, for example, and may include a storage tank (10C) as a cargo tank in which liquid cargo is stored in the hull (10S).

[0020] The storage tank (10C) may be constructed with a double insulation structure for insulating liquid cargo such as cryogenic LNG. For example, the storage tank (10C) may include a primary barrier (not shown), a secondary barrier (not shown), and insulation panels (13, 14).

[0021] The primary barrier can form the inner wall of the storage tank (10C). The primary barrier can primarily seal the liquid cargo and prevent its leakage. The primary barrier is directly exposed to the liquid cargo stored inside the storage tank (10C). The primary barrier can be made of a material resistant to cold (e.g., stainless steel).

[0022] When liquid cargo is stored in the storage tank (10C), the temperature of the primary barrier is cooled to an ultra-low temperature, and when liquid cargo is not stored, the temperature is maintained at room temperature. Therefore, as the temperature of the primary barrier changes from an ultra-low temperature to room temperature, thermal deformation may occur in the primary barrier.

[0023] The primary barrier may be provided in the form of a flat plate with irregularities formed thereon to prevent damage caused by thermal deformation. The irregularities formed on the primary barrier perform a buffer function to accommodate thermal deformation, thereby preventing the primary barrier from being damaged by thermal deformation.

[0024] The secondary barrier may be provided with a second panel (13b, 14b) between it and the hull (10S). The secondary barrier secondarily seals the liquid cargo and prevents its leakage following the primary barrier.

[0025] Here, the secondary barrier covers the front of the second panel (13b, 14b), and the sheet (T) forming part of the secondary barrier covers the gap between the second panel (13b, 14b) and can be installed by the bonding equipment (50).

[0026] The insulation panels (13, 14) perform an insulation function. The insulation panels (13, 14) may be made of a material with excellent insulation properties. The insulation panels (13, 14) may be provided on the flat surface and the corner surface, respectively.

[0027] For example, a plurality of insulation panels (13, 14) may include a first panel (13a, 14a), a second panel (13b, 14b), and a third panel (13c, 14c).

[0028] The first panel (13a, 14a) may be placed between the first barrier and the second barrier. The second panel (13b, 14b) may be installed on the hull (10S) and may form the outer wall of the storage tank (10C).

[0029] A plurality of insulation panels (13, 14) may be spaced apart from each other at a predetermined interval, and a first spacing groove (P1) and a second spacing groove (P2), which are spacing spaces, may be formed between the plurality of insulation panels (13, 14).

[0030] Insulating material (not shown) may be filled in the spaced-apart areas (first gap groove (P1) and second gap groove (P2)) between the insulating panels (13, 14). For example, insulating material such as polyurethane foam may be filled between the first panels (13a, 14a). Insulating material such as glass fiber may be filled in the gaps between the second panels (13b, 14b). Due to these insulating materials, the gaps between the insulating panels (13, 14) are filled, and a buffer function is performed to accommodate the contraction and expansion between the insulating panels (13, 14).

[0031] The third panel (13c, 14c) is provided on one side (see FIG. 2, top surface) of the first panel (13a, 14a) to provide rigidity to the insulation panel (13, 14) and prevent the shape of the insulation panel (13, 14) from being deformed.

[0032] According to the embodiment, the third panel (13c) may be made of plywood and the third panel (14c) may be made of metal (e.g., stainless steel), but this is merely one example and is not limited thereto.

[0033] And with reference to FIG. 3, a second panel (13b, 14b) is installed on the hull (10S), and a first panel (13a, 14a) may be placed on one side (upper side, according to FIG. 3) of the second panel (13b, 14b), and a first spacing groove (P1) may be formed between a plurality of second panels (13b, 14b), and a second spacing groove (P2) may be formed between a plurality of first panels (13a, 14a).

[0034] Referring to FIG. 4, the first gap groove (P1) can be shielded by a sheet (T), and the sheet (T) can be attached to the bottom surface (upper surface of the second panel (13b, 14b)) of the second gap groove (P2) through an adhesive (G) to serve as a secondary barrier. That is, the sheet (T) can form a secondary barrier that prevents leakage of liquid cargo from the storage tank (10C).

[0035] And the sheet (T) may be provided as a triplex, but is not limited thereto, and a sheet (T) of various materials may be provided. Additionally, the sheet (T) may include a tape (not shown) provided at the edge, and the tape may be attached to the bottom surface of the second spacing groove (P2) to serve to trap the adhesive (G) when the bonding equipment (50) attaches the sheet (T).

[0036] Below, a support device (100) for cargo tank manufacturing equipment is described to facilitate the use of bonding equipment (50) for installing a sheet (T) on the second panel (13b, 14b).

[0037] Here, the support device (100) for cargo tank manufacturing equipment is intended to support the manufacturing equipment for manufacturing a cargo tank. In the embodiment of the present invention, the manufacturing equipment is described as being bonding equipment (50), but it is not limited thereto. It is noted that the manufacturing equipment supported by the support device (100) for cargo tank manufacturing equipment may be various types of equipment (welding equipment) or materials (e.g., insulation panels) for manufacturing a cargo tank. It is also noted that the shape of the equipment support (113) of this embodiment may be modified in accordance with the shape / structure, etc. of the equipment and materials.

[0038] In addition, prior to the description of the support device (100) for the cargo tank manufacturing equipment, referring again to FIGS. 3 and FIGS. 4, for example, a slit (S) is provided in the insulation panel (13, 14), and a bonding device (50) is inserted into the slit (S) to manufacture the storage tank (10C).

[0039] However, as shown in Fig. 2, in order for the storage tank (10C) to be provided with a double insulation structure such as a hexagon or an octagon, there is a problem in that the worker must bear the weight of the bonding equipment (50) in a difficult position for the installation of the bonding equipment (50), such as on an upward inclined section (see inclined surface (12)) or a vertical section (see vertical surface (11)).

[0040] In particular, the weight of the bonding equipment (50) is 80 kg, so there is a difficulty in having to handle the bonding equipment (50) by several workers even for preparation for bonding work, so the support device (100) for the cargo tank manufacturing equipment of this embodiment is provided to improve this.

[0041] With reference again to FIGS. 3 and 4, the support device (100) for cargo tank manufacturing equipment supports the weight of the bonding equipment (50) while the bonding equipment (50) is inserted into the slit (S) provided in the insulation panel (13, 14), and when the bonding equipment (50) is separated from the first panel (13a, 14a) after the bonding work (installation of sheet (T)) using the bonding equipment (50), the bonding equipment (50) is not lowered to the floor, but is continuously supported using the support device (100) for cargo tank manufacturing equipment of this embodiment, so that the preparation procedure for the bonding equipment (50) (e.g., the work of lifting the bonding equipment (50) back from the floor so that the bonding equipment (50) is placed adjacent to the area of ​​the insulation panel (13, 14) where the bonding work is required) is performed quickly, so that the worker does not have to directly lift the bonding equipment (50), making it easier to manufacture the storage tank (10C).

[0042] Also, although not shown in the drawing, it is noted that the support device (100) for the cargo tank manufacturing equipment is provided on various structures (e.g., scaffolding) for manufacturing the storage tank (10C) of the cargo tank, and can be placed in close proximity regardless of the height of the storage tank (10C).

[0043] Hereinafter, with reference to the drawings, a support device (100) for a cargo tank manufacturing equipment that supports a manufacturing equipment (e.g., bonding equipment (50)) for manufacturing a storage tank (10C) as a cargo tank will be described.

[0044] FIG. 5 is a perspective view illustrating a support device for cargo tank manufacturing equipment according to a first embodiment of the present invention, FIG. 6 is a right side view illustrating a support device for cargo tank manufacturing equipment according to a first embodiment of the present invention, FIG. 7 is a front view illustrating a support device for cargo tank manufacturing equipment according to a first embodiment of the present invention, and FIG. 8 is a rear side view illustrating a support device for cargo tank manufacturing equipment according to a first embodiment of the present invention.

[0045] In addition, FIG. 9 is a left view illustrating a support device for cargo tank manufacturing equipment according to a first embodiment of the present invention, FIG. 10 is a top view illustrating a support device for cargo tank manufacturing equipment according to a first embodiment of the present invention, and FIG. 11 is a bottom view illustrating a support device for cargo tank manufacturing equipment according to a first embodiment of the present invention.

[0046] In addition, FIG. 12 is a drawing showing a part of a multi-axis drive unit of a support device for cargo tank manufacturing equipment according to the first embodiment of the present invention, FIG. 13 is a drawing showing a state in which a support is rotated in a support device for cargo tank manufacturing equipment according to the first embodiment of the present invention, FIG. 14 is a drawing showing a state in which manufacturing equipment is supported at an incline in a support device for cargo tank manufacturing equipment according to the first embodiment of the present invention, and FIG. 15 is a drawing showing a state in which manufacturing equipment is supported vertically in a support device for cargo tank manufacturing equipment according to the first embodiment of the present invention.

[0047] Referring to FIGS. 5 to 15, a support device (100) for cargo tank manufacturing equipment may include a support unit (110), a multi-axis drive unit (120), a body unit (130), and a support (140).

[0048] The support unit (110) can support the bonding equipment (50), which is the cargo tank manufacturing equipment.

[0049] For example, the support unit (110) may include a first support body (111) and an equipment support (113).

[0050] The first support member (111) may be provided as a frame with a width / width (length in the X-axis and Y-axis directions) corresponding to the width / width of the bottom of the bonding equipment (50). However, the first support member (111) is not limited to a frame shape / structure as a configuration for connecting the equipment support (113) that supports the bonding equipment (50), and various variations are possible, such as being provided as a polygonal plate.

[0051] The equipment support (113) is configured to prevent the bonding equipment (50) from falling, for example, the bottom of the bonding equipment (50) may come into contact with the bottom surface and extend vertically from the bottom surface to form a structure that interferes with the bottom of the bonding equipment. As an example, the equipment support (113) may have an 'L' shape, but is not limited thereto.

[0052] As another example, the equipment support (113) is in a form in which the bottom of the bonding equipment (50) is inserted from the top to the bottom, and various variations such as a reservoir shape with an open top or a '∪' shape are possible.

[0053] In other words, the equipment support (113) can be of various structures that support the bottom while restraining the bonding equipment (50) so that it does not move backward and / or forward.

[0054] In addition, the equipment support (113) may support manufacturing equipment other than the bonding equipment (50), and for this purpose, the shape of the equipment support (113) may be changed to a shape / structure for restraining manufacturing equipment other than the bonding equipment (50).

[0055] In addition, the equipment support (113) can be joined to the first support (111) by welding, but can also be joined by bolting, so that it can be replaced in accordance with the manufacturing equipment, and various variations are possible.

[0056] The multi-axis drive unit (120) is configured to adjust the position of the bonding equipment (50) to match the slit (S) position of the insulation panel (13, 14), and can rotate or move the support unit (110) in the up and down direction.

[0057] For example, the multi-axis drive unit (120) may include a first rotation module (121), a second rotation module (122), a lifting module (123), and a cushion unit (124).

[0058] The first rotation module (121) can rotate in a first rotation direction (see curved arrow in FIG. 13) so that the support unit (110) can have an incline corresponding to the inclined surface (11) of the cargo hold, that is, so that the support unit (110) can tilt. For example, the first rotation module (121) may include an upper semicircular plate (121T) and a lower semicircular plate (121B).

[0059] The upper semicircular plate (121T) may be provided to partially overlap the lower semicircular plate (121B) in the vertical direction and may be provided to be rotatable in a first rotational direction by a hinge axis (121S) (see FIG. 12). The upper semicircular plate (121T) may be positioned on the side of the support unit (110) and may have a curved surface facing downward, allowing the support unit (110) to tilt relative to the lower semicircular plate (121B).

[0060] In addition, the upper semicircular plate (121T) may be provided with a first member (121T1) having a semicircular plate at the bottom and a flat plate structure at the top, and a second member (121T2) provided on the upper surface of the first member (121T1) and forming a flat plate structure, and a fixing member (121T3) that selectively fixes the first member (121T1) and the second member (121T2) may be provided.

[0061] The lower semicircular plate (121B) is provided on the second rotation module (122) and connected to the upper semicircular plate (121T) by a hinge axis (121S) to support the upper semicircular plate (121T) so that it can rotate.

[0062] In addition, a plurality of grooves (121H) (see FIG. 12) are formed in the lower semicircle plate (121B) so that it can be fixed after being rotated according to the rotation angle of the upper semicircle plate (121T), and a bolt / nut (121N) is coupled to the groove (121H) so that the tilting state of the upper semicircle plate (121T) can be fixed. Here, one or more grooves (not shown) for the bolt / nut (121N) to pass through may be formed in the upper semicircle plate (121T) (see FIG. 12, one example).

[0063] That is, in order for the upper half-circle plate (121T) rotated in a first rotational direction relative to the lower half-circle plate (121B) to be fixed, a bolt / nut (121N) is fastened and a groove through which the bolt / nut (121N) passes can be formed in each of the lower half-circle plate (121B) and the upper half-circle plate (121T). A plurality of grooves (121H) can be formed in the lower half-circle plate (121B) corresponding to the groove whose position changes according to the rotational angle of the upper half-circle plate (121T).

[0064] The second rotation module (122) can be rotated so that the support unit (110) rotates radially in a planar view. For example, the second rotation module (122) may be provided with a lower body (122A) and an upper body (122B).

[0065] The upper body (122B) can be connected to the first support body (111), and the lower body (122A) can be connected to the upper semicircular plate (121T). The lower body (122A) is provided with a structure that allows rotation, such as a ball / hemisphere, so that the upper body (122B) can be rotated by the lower body (122A). The upper body (122B) can be rotated along the curved surface of the ball / hemisphere, and the inclination of the support unit (110) with respect to the X-axis and Y-axis can be adjusted.

[0066] The lifting module (123) can be adjusted in length in the vertical direction so that the level of the support unit (110) changes. For example, the lifting module (123) is provided as a pneumatic jack, so that the protruding length of the piston (123B) can be adjusted according to the amount of fluid inside the cylinder (123A) according to the inflow and outflow of pneumatic / hydraulic pressure. In addition, the lifting module (123) may be provided with a hydraulic operating footrest (123F) that can be operated by the worker's foot so that the worker can work easily.

[0067] The cushion unit (124) is for finely adjusting the inclination of the support unit (110) when installing the bonding equipment (50) in the slit (S), and can elastically support the support unit (110).

[0068] That is, the center of the support unit (110) is supported in an up-and-down direction by the first rotation module (121) and the second rotation module (122), and is elastically supported by the cushion unit (124) on the outside of the first rotation module (121), so that some shaking / tilting can be provided by an external force (pressing by a worker).

[0069] For example, a number of cushion units (124) (e.g., three or four, etc.) are provided along the circumference of the second rotation module (122) from the upper part of the first rotation module (121) to elastically support the support unit (110) from all sides, and may be provided as springs. In order to prevent the spring from coming off, a projection / bolt protruding toward the inside of the spring may be provided on each of the first rotation module (121) and the support unit (110).

[0070] The body unit (130) is configured to support the multi-axis drive unit (120) and can be connected to the multi-axis drive unit (120). For example, the body unit (130) is connected to a second support (131) provided as a frame structure, and a rotating module (132), such as a wheel / roller, is provided so that it can be easily moved.

[0071] In addition, a handle (133) extending upward may be provided on the second support (131), and a lug (134) may be provided on the second support (131) so that it may be connected to a transport means such as a trolley by means of a connecting means such as a chain / rope on the lug (134), thereby enabling movement using the equipment (transport means).

[0072] A support (140) may be provided to the body unit (130) as a configuration for supporting the upright position of the bonding equipment (50). For example, the support (140) may protrude from the second support (131) of the body unit (130), and may form a shape that protrudes facing the bottom of the bonding equipment (50) to support the bottom of the bonding equipment (50) while the bonding equipment (50) is positioned perpendicular to the second support (131) and parallel to the vertical surface (11, the wall of the cargo hold).

[0073] The support (140) may have a structure fixed in a position facing the bottom of the bonding equipment (50), but for ease of storage, it may be provided with a structure that is folded to face the upper surface of the second support (131) when stored (see FIG. 14) and rotated outward from the second support (131) so that the bonding equipment (50) is supported in an upright position (see FIG. 13 and FIG. 15), and rotated in a first rotational direction.

[0074] The support device (100) for cargo tank manufacturing equipment according to this embodiment allows the worker (e.g., three people in the past) to support the weight of the equipment with muscle strength during the time the bonding equipment (50) is installed when the heavy bonding equipment (50) is installed, and the work of temporarily placing the bonding equipment (50) on the floor and then lifting it up again for the preparation procedure can be avoided, thereby making it easier to manufacture the cargo tank.

[0075] That is, the support device (100) for cargo tank manufacturing equipment can support cargo tank manufacturing equipment that is difficult for a single worker to handle, and can also rotate / lift to easily handle the manufacturing equipment, thereby improving the musculoskeletal problems of the worker for cargo tank manufacturing and making the work easier.

[0076] Although embodiments of the present invention have been described above with reference to the attached drawings, those skilled in the art will understand that the present invention may be implemented in other specific forms without changing its technical concept or essential features. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive. Explanation of the symbols
