Abstract
Description
Technical Field
[0001] This utility model relates to the field of epoxy resin coating technology for ship cargo holds, and more particularly to an epoxy resin coating equipment for ship cargo holds. Background Technology
[0002] The hull for transporting liquefied natural gas (LNG) refers to the LNG hull, which is widely used in international energy trade, energy supply, and gas supply to offshore platforms. The hull of a ship transporting LNG is generally equipped with a hemispherical cargo hold shell for storing LNG. The lower end of the cargo hold shell is open, and an installation ring is set at the lower end of the cargo hold shell. The installation ring has pre-drilled holes, and it can be fixed to the hull with bolts later.
[0003] After the hemispherical ship cargo hold shell is manufactured on the workbench, in order to improve the corrosion resistance and durability of the inner wall of the ship cargo hold, multiple arc-shaped carbon fiber inner plates will be bonded to the inner wall of the ship cargo hold. Therefore, an epoxy resin coating device for the inner wall of the hemispherical ship cargo hold shell is required on the workbench.
[0004] Currently, existing epoxy resin coating devices for the inner wall of hemispherical ship cargo holds on workbenches produce a significant amount of volatile odorous gases during the epoxy resin coating process, resulting in residual odor. Prolonged exposure to these odorous gases on the workbench can cause health problems for workers, thus contributing to the odor residue issue in the epoxy resin coating device for the inner wall of hemispherical ship cargo holds on workbenches.
[0005] Meanwhile, the existing epoxy resin coating device for the inner wall of the hemispherical ship cargo hold shell in the workbench has weak clamping and anti-detachment stability for the hemispherical ship cargo hold shell.
[0006] Therefore, we designed a coating device for epoxy resin in ship cargo holds to meet the needs of practical applications. Utility Model Content

Detailed Implementation
[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0031] Reference Figures 1-6 An epoxy resin coating equipment for ship cargo holds includes a processing frame 1, a stair plate 11 and a workbench 2 on the processing frame 1, an outer shell 3 above the workbench 2, an mounting ring 31 on the outer shell 3, an upper support 4 and a glue storage tank 6 on the processing frame 1, a purification box 8 and an upper cylinder 41 on the upper support 4, a lifting frame 42 on the cylinder rod of the upper cylinder 41, a clamping cylinder 5 on the lifting frame 42, a cylinder rod 51 slidably connected inside the clamping cylinder 5, an upper clamping block 52 on the cylinder rod 51, a lower clamping block 53 and a damping layer 521 on the upper clamping block 52, a connecting pipe 61 connected to the glue storage tank 6, a glue extraction pump 62 connected to the connecting pipe 61, a glue delivery pipe 7 connected to the glue extraction pump 62, and an adjusting glue pipe 71 connected to the glue delivery pipe 7.
[0032] The purification box 8 is connected to an air intake pipe 9, and an air intake cover 91 is provided on the air intake pipe 9. The purification box 8 contains a purification filter element 81 and an exhaust fan 82.
[0033] The upper surface of the workbench 2 is provided with an anti-slip layer 21, and the upper clamping block 52 is provided with a damping layer 521. The outer shell body 3 and the mounting ring 31 are a set, which is the outer shell of the cargo hold used on the hull of the liquefied natural gas transport ship to store liquefied natural gas. This is existing technology, and some existing structures are not drawn and labeled, so there is no need to elaborate.
[0034] The stair tread 11 is a commonly used stair tread structure, which makes it convenient for workers to step up to the workbench 2 for the subsequent glue application.
[0035] It should be further noted that the end of the upper clamping block 52 facing the outer shell body 3 has an arc-shaped structure, which realizes stable clamping of the arc-shaped outer wall of the outer shell body 3.
[0036] The damping layer 521 is located at the end of the upper clamping block 52 facing the outer shell body 3. The damping layer 521 is made of PU polyurethane damping coating material, which has excellent damping and anti-slip properties, and is wear-resistant and durable.
[0037] It should be further noted that the lower clamping block 53 has a hook-shaped structure and is matched and snapped into the mounting ring 31. Both the lower clamping block 53 and the upper clamping block 52 are made of hard alloy steel. The hook-shaped structure of the lower clamping block 53 can stably clamp the side wall and bottom of the mounting ring 31 and support the bottom.
[0038] It should be further noted that the glue tube 71 is connected to a glue spray head 72, and the glue spray head 72 is equipped with an operating handle 73. There are two symmetrical operating handles 73 on the left and right sides, which makes it convenient for the operator to hold with both hands and improves the stability during glue application.
[0039] It should be further explained that the intake pipe 9 has an overall bent structure and passes through the upper bracket 4 to connect with the purification filter element 81. The purification filter element 81 is a coconut shell activated carbon structure. The coconut shell activated carbon filter element is made by high-temperature activation and carbonization treatment, and is loaded with photocatalyst and carbon fiber. It has a lot of tiny pores inside, which can effectively filter and purify the volatile odor gases into clean air. It is durable.
[0040] It should be further explained that the glue delivery tube 7 vertically runs through the processing frame 1 and the worktable 2. The adjusting glue tube 71 is a metal corrugated tube structure. When the operator holds the operating handle 73 with both hands to spray glue evenly onto the inner wall of the outer shell 3, the metal corrugated tube itself will expand and contract, but this will affect the delivery of epoxy resin glue.
[0041] It should be further noted that the air intake hood 91 is tilted towards the outer shell 3. There are two air intake hoods 91 that are symmetrical on the left and right. The air intake hood 91 and the air intake pipe 9 are made of stainless steel, which is durable and corrosion resistant, and can completely remove the odorous gases that are generated.
[0042] A dustproof net 83 is provided on the outer wall of the purification box 8. At the same time, a similar dustproof net 83 is provided at the opening of the suction hood 91. The dustproof net 83 is made of non-woven fabric, which can prevent external dust particles from entering the suction fan 82 when not in use.
[0043] It should be further noted that the anti-slip layer 21 is located on the upper surface of the workbench 2. The anti-slip layer 21 is a silicone pad with a thickness of 30 mm. The silicone pad has excellent damping and anti-slip properties, which improves the clamping damping and anti-slip properties of the upper clamping block 52 on the outer shell body 3.
[0044] Operating procedure: When the outer casing 3 is stably clamped and supported, the operator walks up the stairs 11 to the workbench 2. Then, the glue pump 62 and the suction fan 82 are started. The operator holds the operating handle 73 with both hands. At this time, the glue pump 62 extracts the epoxy resin glue pre-stored in the glue storage tank 6 through the connecting pipe 61. Then, it is sprayed onto the inner wall of the outer casing 3 through the glue delivery pipe 7 and the adjusting glue pipe 71 and the glue spray head 72. Since the adjusting glue pipe 71 is a metal corrugated pipe structure, the operator can evenly spray the glue onto the inner wall of the outer casing 3 by holding the operating handle 73 with both hands (this is existing technology).
[0045] During the spray coating operation, volatile odorous gases are generated. At this time, the already activated suction fan 82 will generate suction force in the suction hood 91, which can completely remove the volatile odorous gases. The odorous gases are then introduced into the purification box 8 through the suction pipe 9. The odorous gases are effectively filtered and purified by the purification filter element 81, and finally discharged through the dust screen 83. This avoids the health problems of the staff being on the workbench 2 with residual odorous gases for a long time, and further avoids the odor residue of the epoxy resin coating device on the inner wall of the hemispherical ship cargo hold shell in the workbench 2.
[0046] Moreover, the outer shell 3 can be suspended as a whole by passing the pre-set lifting rope and hook on the crane through the pre-set perforation on the mounting ring 31. Then, the clamping cylinder 5 is activated, and the cylinder rod 51 on both sides of the clamping cylinder 5 will extend, thereby driving the upper clamping block 52 and the lower clamping support block 53 on both sides to move horizontally. When the upper clamping block 52 on both sides is stably clamped to the arc-shaped outer wall surface of the outer shell 3, at the same time, the lower clamping support block 53 on both sides will also stably clamp and support the side wall and bottom of the mounting ring 31, thus improving the overall clamping and anti-detachment stability of the hemispherical ship cargo hold outer shell.
[0047] In addition, by providing a damping layer 521 structure on the upper clamping block 52, when the upper clamping blocks 52 on both sides are laterally clamped with the outer wall surface of the outer shell body 3, the damping layer 521, which has a damping friction effect, further improves the clamping damping and anti-slip performance of the upper clamping block 52 on the outer shell body 3.
[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
