Description

Technical Field

[0001] This utility model relates to the field of LNG ship interior panel bonding and coating technology, and in particular to an automatic coating device for LNG ship interior panel bonding operations. Background Technology

[0002] LNG carriers are ships that transport liquefied natural gas. They are widely used in international energy trade, energy supply, and gas supply to offshore platforms. LNG carriers typically have arc-shaped compartments on their hulls for storing liquefied natural gas.

[0003] To improve the overall lightweight characteristics of the cabin, multiple curved inner panels made of carbon fiber will be installed on the inner wall of the curved metal shell of the cabin.

[0004] After the outer shell of the arc-shaped compartment is manufactured in the production workshop, in order to ensure the corrosion resistance and durability of the inner wall of the compartment, the inner wall surface of the arc-shaped inner panel needs to be coated first. Then, the coated arc-shaped inner panel is glued to the inner wall of the outer shell of the compartment in the production workshop with epoxy resin. Therefore, the coating equipment for the inner panel bonding operation of the inner wall of the LNG ship's compartment is required.

[0005] Currently, the existing coating equipment used after the bonding of inner panels for the interior walls of LNG ship cabins uses fluorocarbon topcoat, which contains organic solvents such as benzene compounds and ketones. Therefore, it will release gases with irritating odors. Inhalation of these gases may cause dizziness, nausea, and respiratory irritation, and skin contact may cause allergies or dermatitis. This greatly reduces the protective effect of the coating equipment after the bonding of inner panels for the interior walls of LNG ship cabins against the gas volatilization of the environment.

[0006] In addition, the existing coating equipment used for bonding inner panels to the interior walls of LNG ship cabins has weak clamping stability for curved inner panels, which greatly reduces the stability of subsequent coating operations on their inner surfaces.

[0007] To address this, we designed a coating device for the bonding of inner panels on the interior walls of LNG ship cabins, meeting the needs of practical applications. Utility Model Content

[0008] The purpose of this utility model is to address the aforementioned shortcomings in the existing technology by proposing an automatic coating device for bonding LNG ship interior panels.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] Design an automatic coating device for bonding LNG ship inner panels, including a coating base, an inner panel body above the coating base, bolts and a bracket on the coating base, a controller and a vertical cylinder on the bracket, a connecting frame on the cylinder rod of the vertical cylinder, a swing motor on the connecting frame, a connecting block on the motor shaft of the swing motor, a connecting pipe on the connecting block, a paint spray cover on the connecting pipe, a storage tank on the bracket, and a paint pump on the storage tank;

[0012] The coating base is equipped with a purification box, which is equipped with an exhaust hood and a suction pump. The suction pump is connected to a main suction pipe and an exhaust pipe. The main suction pipe is connected to a secondary suction pipe, which is equipped with a side suction hood. The purification box contains a purification core.

[0013] In detail, the connecting frame has an overall L-shaped structure, the swing motor is located on the back end face of the connecting frame, and the vertical central axis of the connecting frame is aligned with the vertical central axis of the inner plate.

[0014] In detail, the paint pump is equipped with a paint delivery pipe and a paint extraction cover. The paint delivery pipe is a metal corrugated pipe structure and its two ends are respectively connected to the inner cavity of the paint pump and the connecting pipe.

[0015] In detail, the inner cavity of the connecting pipe is connected to the inner cavity of the paint spray hood, and the lower opening size of the paint spray hood is not less than the front and rear width of the inner plate.

[0016] In detail, the top plate is a rectangular structure, the top columns are three evenly arranged, and the pressure head is located at one end facing the inner plate.

[0017] In detail, the coating base is a trapezoidal structure, and the bolts are arranged in two symmetrical groups, with two bolts in each group.

[0018] In detail, the auxiliary suction tube is a symmetrical bent tube structure that passes through the support laterally and communicates with the inner cavity of the side suction cover.

[0019] In detail, the purification core is embedded in the inner cavity of the purification box and contacts the lower end face of the exhaust pipe, and the exhaust hood is connected to the inner cavity of the purification box.

[0020] The design scheme proposed in this utility model has the following beneficial effects in application:

[0021] 1. This utility model, by setting a symmetrical suction structure on the coating station and a purification box structure with a purification core on the coating station, can simultaneously and effectively draw volatile harmful gases into the purification box during the comprehensive coating of the inner wall surface of the clamped inner panel. The gases will then be filtered and purified by the purification core and discharged later, avoiding the inhalation of volatile gases with irritating odors that may cause dizziness, nausea, respiratory irritation, or skin allergies or dermatitis. This improves the protection of the coating device against gas volatilization after the bonding of the inner panel of the cabin wall on LNG ships.

[0022] 2. This utility model, through the symmetrical cylinder clamping structure and the three sets of top column structures with pressure heads, achieves three-point positioning, stable damping clamping of the two side walls of the inner plate, which greatly improves the stability of the coating device for the inner plate after the bonding operation of the inner plate of the cabin wall on the LNG ship.

Detailed Implementation

[0031] 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.

[0032] Reference Figures 1-6 An automatic coating device for bonding LNG ship interior panels includes a coating base 1, an inner panel 24 above the coating base 1, bolts 11 and a bracket 3 on the coating base 1, a controller 31 and a vertical cylinder 4 on the bracket 3, a connecting frame 41 on the cylinder rod of the vertical cylinder 4, a swing motor 411 on the connecting frame 41, a connecting block 42 on the motor shaft of the swing motor 411, a connecting pipe 43 on the connecting block 42, a paint spray cover 44 on the connecting pipe 43, a storage tank 5 on the bracket 3, and a paint pump 51 on the storage tank 5.

[0033] The painting base 1 is provided with a side plate 2, the side plate 2 is provided with a clamping cylinder 21, the cylinder rod of the clamping cylinder 21 is provided with a top plate 22, the top plate 22 is provided with a top column 23, and the top column 23 is provided with a pressure head 231.

[0034] The painting stand 1 is equipped with a purification box 6, an exhaust hood 61 and a suction pump 7. The suction pump 7 is connected to a main suction pipe 71 and an exhaust pipe 72. The main suction pipe 71 is connected to a secondary suction pipe 8. The secondary suction pipe 8 is equipped with a side suction hood 81. The purification box 6 is equipped with a purification core 62. The controller 31 has a pre-set PLC that can control the automatic opening and closing of the vertical cylinder 4, the paint pump 51, the swing motor 411 and the suction pump 7 (existing technology).

[0035] The inner panel 24 is the commonly used inner panel of the painting device after the inner panel bonding operation of the inner wall of the LNG ship's cabin.

[0036] It should be further explained that the frame 41 has an overall L-shaped structure, and the swing motor 411 is located on the back end face of the frame 41. The vertical central axis of the frame 41 is aligned with the vertical central axis of the inner plate 24, so as to realize the reciprocating swing spraying of the inner wall surface of the lower inner plate 24.

[0037] It should be further explained that the paint pump 51 is equipped with a paint delivery pipe 52 and a paint extraction cover 53. The paint delivery pipe 52 is a metal corrugated pipe structure and its two ends are respectively connected to the inner cavity of the paint pump 51 and the connecting pipe 43. The metal corrugated pipe can expand and contract with the up and down movement of the connecting pipe 43, but it does not affect the normal delivery of paint.

[0038] It should be further noted that the inner cavity of the connector 43 is connected to the inner cavity of the spray paint cover 44. The lower opening size of the spray paint cover 44 is not less than the front and rear width of the inner plate 24. When the spray paint is applied by reciprocating swinging, the upper inner wall surface of the inner plate 24 can be fully sprayed with paint to avoid omissions.

[0039] It should be further noted that the top plate 22 is a rectangular structure, and the top columns 23 are three evenly arranged to achieve three-point positioning, damping, and stable clamping of the side wall of the inner plate 24.

[0040] The pressure head 231 is located at one end facing the inner plate 24. The pressure head 231 is made of silicone pad material and has damping friction elasticity, which greatly improves the compression damping clamping stability with the side wall of the inner plate 24.

[0041] It should be further noted that the coating base 1 has a trapezoidal structure, which has strong stability. The coating base 1 is made of hard alloy tungsten steel, which has high strength, high temperature resistance, and is easy to weld and process.

[0042] The bolts 11 are arranged in two symmetrical groups, with two bolts in each group. The four bolts 11 can be securely installed on the mounting platform (which is existing technology) at the bottom of the coating base 1.

[0043] It should be further explained that the auxiliary suction pipe 8 is a symmetrical bent tube structure. The auxiliary suction pipe 8 passes through the support 3 laterally and communicates with the inner cavity of the side suction hood 81. The side dimension area of ​​the side suction hood 81 is not less than the side dimension area of ​​the inner plate 24, so as to achieve comprehensive and symmetrical effective suction of the volatile harmful gases.

[0044] It should be further explained that the purification core 62 is embedded in the inner cavity of the purification box 6 and contacts the lower end face of the exhaust pipe 72. The exhaust hood 61 is connected to the inner cavity of the purification box 6. The purification core 62 is a coconut shell activated carbon filter element, which is made of coconut shell as raw material, activated and carbonized at high temperature, and loaded with photocatalyst and carbon fiber. It is an activated carbon filter element with abundant micropores inside, which can effectively adsorb, filter and purify harmful gases and is durable.

[0045] Operating mode: Upon starting controller 31, the PLC within controller 31 first controls the start of vertical cylinder 4, causing the connecting frame 41, connecting pipe 43, and paint spray hood 44 to move downwards as a whole. When the lower end of paint spray hood 44 maintains an effective spraying distance from the inner wall of inner panel 24, the PLC within controller 31 stops vertical cylinder 4 and simultaneously starts paint pump 51 and swing motor 411. Paint pump 51 draws paint from storage tank 5 into connecting pipe 43 through paint delivery pipe 52 and paint spray hood 53, and then sprays it downwards through paint spray hood 44.

[0046] At the same time, the swing motor 411 drives the connecting pipe 43 and the paint spraying nozzle 44 to swing back and forth at a certain swing angle through the connecting block 42, thereby realizing the reciprocating swing-type automatic painting of the inner wall surface of the lower inner plate 24.

[0047] During the painting process, harmful gases are released. The PLC in the controller 31 will also start the suction pump 7 at the same time. At this time, suction will be generated in the side suction hoods 81 on both sides, which can symmetrically and effectively draw the released harmful gases into the purification box 6 through the auxiliary suction pipe 8 and the main suction pipe 71. Then, it will be discharged into the purification core 62 through the drain pipe 72, where it will be filtered and purified. Finally, it will be discharged through the exhaust hood 61, avoiding the inhalation of irritating gases that may cause dizziness, nausea, respiratory irritation, and skin contact that may cause allergies or dermatitis. This improves the protection of the painting device against gas volatilization after the bonding of the inner panel of the cabin wall on the LNG ship.

[0048] Moreover, by activating the two clamping cylinders 21, the two top plates 22 move synchronously toward the inner plate 24. Once the pressure heads 231 on the two sets of top columns 23 are stably damped and clamped to the two end side walls of the inner plate 24, the clamping cylinders 21 are stopped, thus achieving three-point positioning and stable damping clamping of the two side walls of the inner plate 24. This greatly improves the stability of the coating device for the inner plate 24 after the bonding operation of the inner plate for the inner wall of the LNG ship's cabin.

[0049] In addition, by setting a bracket 3 with a swing-type spray painting structure on the painting seat 1, the inner wall surface of the inner panel 24 can be uniformly coated in a reciprocating manner, which greatly improves the uniformity of the coating device for the inner panel 24 after the bonding operation of the inner panel of the cabin wall on the LNG ship.

[0050] 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.
