Hereinafter, a liquefied natural gas storage tank will be described first, and then an auxiliary secondary barrier bonding apparatus for a liquefied natural gas storage tank according to an embodiment of the present invention will be described.

3 is an exemplary cross-sectional view of a liquefied natural gas storage tank. The bonding apparatus 100 (shown in FIG. 4) according to an embodiment of the present invention can be used to construct a storage tank 10 for storing Liquefied Natural Gas (LNG). The liquefied natural gas storage tank 10 may be, for example, an LNG carrier, an LNG regasification vessel, an LNG floating production storage offloading (FPSO) facility, or an LNG floating storage and re- (Floating Storage Regasification Unit). The liquefied natural gas storage tank 10 is, for example, designed to cool a liquefied natural gas to a cryogenic temperature of -163 DEG C or lower and to store it in a liquid state to prevent the cold air from affecting the hull M of the liquefied natural gas carrier do. For this purpose, the liquefied natural gas storage tank 10 may have a double insulation structure.

The external thermal insulation panel 14 is installed, for example, on the hull M of the liquefied natural gas carrier, and forms the outer wall of the liquefied natural gas storage tank 10. [ The external thermal insulation panel 14 performs a heat insulation function between the secondary barrier 12 and the hull M and is made of a material excellent in heat insulation. The outer heat insulating panel 14 may include a first heat insulating member 14a and a first protective member 14b attached to the first heat insulating member 14a. The first heat insulating member 14a may be made of a material having excellent heat insulation such as polyurethane foam. The external insulating panel 14 can be fixed to the hull M by means of a stud bolt (not shown), for example, via the first protective member 14b. The first protection member 14b may be made of a plywood material, for example, by providing rigidity to the external heat insulating panel 14 to prevent the external heat insulating panel 14 from being deformed. In order to prevent the external heat insulating panel 14 from being damaged when the external heat insulating panel 14 expands, the external heat insulating panels 14 may be disposed at a predetermined distance from each other.

In FIG. 3 (A), the upper part of the primary barrier 11 is the inner space of the storage tank 10 where liquefied natural gas is stored. The primary barrier 11 is directly exposed to the liquefied natural gas stored in the liquefied natural gas storage tank 10 and is resistant to low-temperature brittleness such as, for example, stainless steel, aluminum alloy, Invar, May be provided as a material. When the liquefied natural gas is stored in the liquefied natural gas storage tank 10, the temperature of the liquefied natural gas is cooled to a cryogenic temperature. If the liquefied natural gas is not stored, the temperature of the primary barrier 11 is maintained at room temperature . The primary barrier 11 may be provided in a corrugated membrane structure in which protrusions and depressions 11a are formed. As the temperature changes from a cryogenic temperature to a room temperature, thermal deformation may occur in the primary barrier 11. The unevenness 11a formed in the primary barrier 11 acts as a buffer in thermal deformation of the primary barrier 11 Thereby preventing breakage of the primary barrier 11.

The first wheel frame 151 and the second wheel frame 152 are provided so that their longitudinal directions are parallel to the longitudinal direction of the frame 100 of Fig. A first main wheel 154, a second main wheel 155 and a rolling member 156 are installed on the first wheel frame 151 and the second wheel frame 152.

The body 153 connects the first wheel frame 151 and the second wheel frame 152 and fixes them to each other. For example, the body 153 may be provided in the shape of a rectangular plate when viewed from above. One end of the body 153 may be connected to the center of one side of the first wheel frame 151 and the other end may be connected to the center of one side of the second wheel frame 152.

The first main wheel 154 may roll in contact with the side surface of the panel to move the frame 10. [ FIGS. 9 and 10 are views showing a state where the bonding apparatus of FIG. 4 is installed in the 'C' portion of FIG. 3. FIG. 9 and 10, according to one embodiment, the first main wheel 154 is provided on the upper part of the front end of each of the first wheel frame 151 and the second wheel frame 152, respectively. According to one embodiment, the panel may be an inner heat-insulating panel 13. The first main wheel 154 can move in a rolling contact with the side surface of the second protective member 13a of the inner heat insulating panel 13 to move the frame 110. [ The first main wheel 154 includes an upper plate 154a, a lower plate 154b, and a wheel body 154c. The upper plate 154a and the lower plate 154b are provided in the form of a disc. The upper plate 154a and the lower plate 154b are provided so as to face each other. The wheel body 154c is provided in a cylindrical shape. The wheel body 154c connects the upper plate 154a and the lower plate 154b. The upper plate 154a and the lower plate 154b are provided so that their side surfaces protrude outward from the wheel body 154c. Therefore, when the traveling device 150 is installed between the heat insulating panels 13, the second protecting member 13a is inserted between the upper plate 154a and the lower plate 154b. To this end, a step S may be formed at a side end of the second heat insulating member 13b so as to be stepped inward.

7 and 8, the second main wheel 155 is provided on the upper portion of the other end of each of the first wheel frame 151 and the second wheel frame 152. [ In addition, the configuration, shape, and function of the second main wheel 155 are similar to those of the first main wheel 154 described above. The first main wheel 154 and the second main wheel 155 are provided so that their side surfaces protrude outward from the first wheel frame 151 and the second wheel frame 152.

Figs. 11 and 12 are views for explaining the rolling member 156. Fig. Referring to FIGS. 7, 11 and 12, the panel includes a first panel 210 and a second panel 220. The first panel 210 and the second panel 220 are spaced apart from each other along the traveling direction of the traveling device 150. The traveling device 150 travels from the first panel 210 toward the second panel 220. That is, the traveling device 150 travels between the first panel 210 and the second panel 220 which are spaced apart from each other. In this case, the height of the second panel 220 is set so that the height of the first main wheel 154 The height of the second panel 220 is higher than the height of the first panel 210 or the traveling device 150 moves from the first panel 210 to the second panel 220 The height of the second panel 220 may become higher than the height of the first main wheel 154 due to the deflection of the front portion due to gravity before the first main wheel 154 is driven. The rolling member 156 raises the front portions of the first wheel frame 151 and the second frame 152 to move the first panel 210 and the second panel 220 to the second panel 220, Thereby preventing the traveling device 150 from being disengaged from the panel 220. The rolling member 156 is mounted on the first wheel frame 151 and the second wheel frame 152 in front of the first main wheel 154 doxy Is. The rolling member 156 includes a guide roller (156a), the support (156b) and a shaft (156c).

According to one embodiment, the guide roller 156a may have a cylindrical shape. The guide roller 156a is provided with its longitudinal direction perpendicular to the longitudinal direction of the first wheel frame 151 and the second wheel frame 152 when viewed from above. The height of the lower end of the guide roller 156a may be the same as the height of the lower end of the upper plate 154a of the first main wheel 154. [ When the traveling device 150 enters the second panel 220 during traveling and the height of the second panel 220 is higher than the entry height of the first main wheel 154, The guide roller 156a is rotated by the collision between the upper edge and the lower portion of the guide roller 156a. The guide roller 156a is raised to the upper portion of the second panel 220 by the rotation. Thus, the height of the second panel 220 and the height of the first main wheel 154 are aligned with each other. Therefore, the traveling device 150 is prevented from separating from between the panels.

The support frame 156b is provided so as to protrude upward from one end of the front of the first wheel frame 151 and the second wheel frame 152. [ The guide roller 156a is mounted on the shaft 156c protruding from the side surface of the support table 156b so as to rotate along the circumferential direction thereof.

13 is a perspective view showing a rolling member 156 according to another embodiment of the present invention. Referring to FIG. 13, the guide roller 156a may alternatively be provided in a spherical shape. In this case, the configuration, structure, and function of the rolling member 156 are similar to those of the above-described embodiment.

Referring again to Figs. 4 to 6, the heating unit 160 heats the adhesive agent G applied on the primary secondary barrier 12b to cure the adhesive agent G. Fig. When heat is applied to the adhesive agent G, the adhesive agent G is cured and the adhesive agent G and the sheet T can be fixed to the coated surface. The heating unit 160 may include a link 161, an actuator 162, a heating plate 163, and a heater 164. The link 161 may be installed so as to extend downward from the frame 110. The heating plate 163 may be installed at the lower end of the link 161. The heating plate 163 may be provided in a plate shape. The lower surface of the heating plate 163 may be provided to face the application surface. The heater 164 can heat the heating plate 163 to a predetermined temperature. For example, the heater 164 may be embodied as a heating wire installed inside the heating plate 163. The actuator 162 can move the link 161 up and down or adjust the length of the link 161. [ As the actuator 162 adjusts the link 161 to extend toward the application surface, the heating plate 163 contacts or comes into contact with the sheet T applied to the application surface. The heating plate 163 heated to a predetermined temperature by the heat generated by the heater 164 applies heat to the sheet T and the adhesive G so that the sheet T is cured and attached to the coated surface, Barriers can be constructed.

Meanwhile, the bonding apparatus 100 may further include a controller and a memory (not shown). The controller can receive signals and process the information and thus control other components of the bonding apparatus 100. The controller may be implemented as a computer or similar device using hardware, software, or a combination thereof. In hardware, the controller may be implemented as an application specific integrated circuit (ASIC), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field programmable gate arrays (FPGAs) micro-controllers, microprocessors, or electrical devices that perform similar control functions. Also, the software may be implemented by software code or software applications written in one or more programming languages. The software may be executed by a hardware implemented control unit. The software may be installed by being transmitted from an external device such as a server in the hardware configuration described above. The memory (not shown) may store information such as a travel speed of the bonding apparatus and an adhesive discharge amount setting value for each travel region.

14 to 17 are views for explaining a first main wheel 154 according to another embodiment of the present invention. 13 and 14, unlike the above-described embodiment, the traveling device does not include the rolling member 156, and the first main wheel 154 moves from the first panel 210 to the second panel 220, When the height of the second panel 220 is lower than the height of the first main wheel 154 when the second panel 220 enters the first panel 210, The first main wheel 154 lowers the front portions of the first wheel frame 151 and the second wheel frame 152 to prevent the first main frame 154 and the second wheel frame 152 from departing from each other. For example, the first main wheel 154 is provided to be inclined with respect to the longitudinal direction of the first wheel frame 151 and the second wheel frame 152. In addition, the first main wheel 154 is inclined to be lowered toward the front. The distance between the upper plate 154a and the lower plate 154b of the first main wheel 154 is provided to be longer than the distance between the upper plate and the lower plate of the second main wheel 155. [ In the case where the panel is the heat insulating panel 13 of Fig. 3, the manner in which the first main wheel 154 of Figs. 14 to 17 is normally installed in the heat insulating panel 13 is similar to that of Figs. 9 and 10. Therefore, when the height of the second panel 220 is lower than the height of the entrance when traveling between the heat insulating panels and the first panel 210 and the second panel 220 are the inner heat insulating panel 13 of FIG. 3 The upper end of the lower plate 154b of the first main wheel 154 is brought into contact with the lower end of the second protective member 13a and the first main wheel 154 is inclined, The height of the second panel 220 and the entry height of the second panel 220 coincide with each other. This prevents the traveling device 150 from being separated from between the panels.

18 is a side view showing a traveling device according to another embodiment of the present invention. 18, the traveling device 150 includes a rolling member 156, and the first main wheel 154 and the second wheel frame 152 are disposed so as to be lowered toward the front And is provided to be inclined with respect to the longitudinal direction. In this case, the configuration, structure, and function of the rolling member 156 and the first main wheel 154 are similar to those of the above-described embodiments. Therefore, when the height of the second panel 220 is higher or lower than the entry height, the height of the second panel 220 can be matched with the entry height.

The above embodiments have described the case where the traveling device 150 is applied to the bonding device of the secondary secondary barrier for the liquefied natural gas storage tank. Alternatively, the traveling device 150 of the present invention can be applied to all the devices that run between the panels.
