Description

Technical Field

[0001] This invention relates to the field of marine technology, and in particular to a method for installing marine outfitting components. Background Technology

[0002] Hatch covers are sealing devices installed on cargo hatch openings, serving as crucial cargo passage equipment for closing the cargo hold. Currently, the installation sequence for hatch cover systems is as follows: erecting the hatch coaming, hatch cover fabrication, hatch cover placement on the ship, outfitting component installation, and inspection. Existing technology has the following drawbacks: outfitting component installation depends on the actual position of the hatch cover; the hatch cover must be placed on the ship before outfitting components can be installed, making simultaneous installation impossible and resulting in a long installation cycle for the hatch cover system. Summary of the Invention

[0003] The purpose of this invention is to provide a method for installing ship outfitting components, which is simple to operate, has high installation accuracy, and a short installation cycle for the overall hatch cover system.

[0004] To achieve this objective, the embodiments of the present invention adopt the following technical solutions:

[0005] A method for installing ship outfitting components is provided, comprising the following steps:

[0006] S10. Before the hatch cover is installed into the ship section, the theoretical positioning dimensions of the outfitting components and hatch coaming are set according to the manufacturing data of the hatch cover.

[0007] S20. Fabricate the hatch coaming, wherein the hatch coaming has a hatch coaming panel;

[0008] S30. Welding reinforcements onto the hatch coaming panel;

[0009] S40. Weld the assembly consisting of the hatch coaming and the reinforcing member onto the segment, draw the hatch coaming transverse center line and the hatch coaming longitudinal center line on the hatch coaming panel, and take the intersection of the hatch coaming transverse center line and the hatch coaming longitudinal center line as the origin of the hatch coaming coordinates.

[0010] S50. Draw the transverse center line and the longitudinal center line of the reinforcing member on the hatch coaming panel.

[0011] S60. Locate the theoretical positioning dimension of the outfitting component using the origin of the hatch coaming coordinates. Compare the dimensional deviations of the theoretical positioning dimension of the outfitting component with the transverse centerline and longitudinal centerline of the reinforcing member. Adjust the actual installation position of the outfitting component and install the outfitting component onto the hatch coaming panel.

[0012] As a preferred method for installing ship outfitting components, step S60 further includes adjusting the position of the reinforcing member. The position of the reinforcing member is determined based on the deviation between the theoretical positioning dimensions of the outfitting component and the transverse centerline and longitudinal centerline of the reinforcing member.

[0013] As a preferred embodiment of the installation method for ship outfitting components, the outfitting components include a guiding device, the guiding device includes a fixing member and a first adjusting block, the first adjusting block is fixed to one side of the fixing member along a first direction, the reinforcing member below the guiding device is a first reinforcing member, the dimension of the first reinforcing member along the first direction is t1, the dimension of the first adjusting block along the first direction is T1, the theoretical positioning coordinates of the fixing member are (Fx1, Fy1), the actual installation coordinates of the fixing member are (Fx1′, Fy1′), the fixing member is symmetrical about a first centerline on both sides along the first direction, and the perpendicular distance between the first centerline and the longitudinal centerline of the first reinforcing member along the first direction is δ1;

[0014] There is no need to adjust the position of the first reinforcing member when δ1 meets the following conditions;

[0015] when When Fx1′=Fx1, Fy1′=Fy1, the guide device is installed using its theoretical positioning coordinates; and / or,

[0016] when hour, Adjust the actual installation coordinates of the guide device to install the guide device; and / or,

[0017] when hour, Adjust the actual installation coordinates of the guide device to install the guide device; and / or,

[0018] when At that time, |Fx1′-Fx1|=T1, |Fy1′-Fy1|=T1;

[0019] When δ1 meets the following conditions, the position of the first reinforcing member needs to be adjusted to the theoretical positioning coordinate position of the guide device.

[0020] when hour, Adjust the actual installation coordinates of the guide device to install the guide device.

[0021] As a preferred embodiment of the installation method for ship outfitting components, the outfitting components further include an anti-jump device. The anti-jump device includes two first support plates spaced apart along a first direction. The two first support plates are connected at their ends along the height direction by a first connecting plate and a second connecting plate, respectively. The first connecting plate, the second connecting plate, and the two first support plates enclose an anti-jump groove, which is used to limit the jumping of the hatch cover.

[0022] As a preferred embodiment of the installation method for ship outfitting components, the two first support plates are symmetrical about the second centerline along the first direction. The reinforcing member below the anti-jump device is the second reinforcing member. The dimension of the second reinforcing member along the first direction is t2. The distance between the second centerline and the first support plate is T2. The theoretical positioning coordinates of the anti-jump device are (Fx2, Fy2). The actual installation coordinates of the anti-jump device are (Fx2′, Fy2′). The distance between the second centerline and the longitudinal centerline of the second reinforcing member along the first direction is δ2.

[0023] There is no need to adjust the position of the second reinforcing member when δ2 meets the following conditions;

[0024] when When Fx2′=Fx2, Fy2′=Fy2, the anti-jump device is installed using its theoretical positioning coordinates; and / or,

[0025] when hour, Adjust the actual installation coordinates of the anti-jump device to install the anti-jump device; and / or,

[0026] when hour, Adjust the actual installation coordinates of the anti-jump device to install the anti-jump device; and / or,

[0027] when When |Fx2′-Fx2|=T2, |Fy2′-Fy2|=T2, adjust the actual installation coordinates of the anti-jump device to install the anti-jump device;

[0028] When δ2 meets the following conditions, the position of the second reinforcing member needs to be adjusted to the theoretical positioning coordinate position of the anti-jump device.

[0029] when hour, Adjust the actual installation coordinates of the anti-jump device to install the anti-jump device.

[0030] As a preferred embodiment of the installation method for ship outfitting components, after step S60, step S70 is further included, providing a hatch cover. The anti-jump device further includes a sealing assembly and an anti-jump shaft. The sealing assembly includes a mounting bracket, a rubber groove, and a rubber strip. The mounting bracket and the anti-jump shaft are spaced apart on one side of the hatch cover, and the rubber groove is located below the mounting bracket. The rubber groove abuts against the hatch coaming panel through the rubber strip. The anti-jump shaft can be inserted into the anti-jump groove. The second connecting plate is positioned away from the hatch coaming panel relative to the first connecting plate. The installation height Fz1 of the second connecting plate is calculated using Fz1 = H3 - H2 + G1 + H1 - C, where H3 is the flatness of the top side of the anti-jump shaft measured relative to the baseline, H2 is the flatness of the rubber groove adjacent to the rubber strip measured relative to the baseline, G1 is the theoretical gap between the anti-jump shaft and the second connecting plate, H1 is the original dimension of the rubber strip along the height direction, and C is the compression amount when the rubber strip is pressed deep relative to the baseline.

[0031] As a preferred embodiment of the installation method for ship outfitting components, the sealing assembly further includes a third connecting plate, a mounting base, and a second adjusting block. The third connecting plate is disposed on the side of the mounting frame away from the hatch cover. The third connecting plate is connected to the hatch coaming panel via the mounting base. The second adjusting block is disposed between the third connecting plate and the mounting base or between the mounting base and the hatch coaming panel. The thickness Z of the second adjusting block is calculated using Z = H4 - H2 + H1 - C, where H4 is the flatness of the side of the third connecting plate adjacent to the hatch coaming panel, measured relative to the baseline.

[0032] As a preferred method for installing ship outfitting components, the third connecting plate is connected to the mounting base by bolts. According to the calculation result Z = H4 - H2 + H1 - C, the second adjusting block is an adjusting shim or adjusting pad. When Z < 6 mm, the adjusting shim is provided between the third connecting plate and the mounting base, and the mounting base is welded to the hatch coaming panel. When Z ≥ 6 mm, the adjusting pad is provided between the mounting base and the hatch coaming panel, and the adjusting pad is welded to the mounting base and the hatch coaming panel on both sides along the height direction, respectively.

[0033] As a preferred method for installing ship outfitting components, the sealing assembly further includes a clamping block. When C ≤ 18 mm, the rubber strip directly abuts against the hatch coaming panel when 6 mm < C ≤ 18 mm; when C ≤ 6 mm, the clamping block needs to be installed between the rubber strip and the hatch coaming panel, and the clamping block is welded to the hatch coaming panel.

[0034] As a preferred embodiment of the installation method for ship outfitting components, the outfitting components further include locating pins, the theoretical locating dimensions of which are (Fx3, Fy3), and the actual installation dimensions of which are (Fx3′, Fy3′), where |Fx3′-Fx3|=K, |Fy3′-Fy3|=K, and K is the tolerance compensation amount of the locating pin.

[0035] The beneficial effects of this invention are as follows: by marking the transverse and longitudinal center lines of the reinforcing member on the hatch coaming panel, the theoretical positioning dimensions of the outfitting component are compared with the deviations of the transverse and longitudinal center lines of the reinforcing member, so as to correct the actual installation dimensions of the outfitting component, effectively ensuring the installation accuracy of the outfitting component, and the outfitting component can be directly installed on the hatch coaming panel in advance during the hatch cover manufacturing process, effectively shortening the installation cycle of the hatch cover system.

[0045] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0047] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0048] like Figure 1 and Figure 2As shown, the installation method of ship outfitting components according to an embodiment of the present invention includes the following steps: S10, before the hatch cover 1 is installed to the ship section, the theoretical positioning dimensions of the outfitting components and the hatch coaming are set according to the manufacturing data of the hatch cover 1.

[0049] S20. Fabricate the hatch coaming, which has a hatch coaming panel 2;

[0050] S30. Welding reinforcements onto the hatch coaming panel 2. During the forming process of the hatch coaming panel 2, it is usually made up of multiple small panels welded together. Reinforcings are welded at the weld seams of the small panels. The reinforcements effectively strengthen the connection strength between the small panels and also improve the structural strength of the outfitting parts welded onto the hatch coaming panel 2 to ensure the connection strength of the outfitting parts.

[0051] S40. Weld the components consisting of the hatch coaming and the reinforcing member onto the segment. Draw the hatch coaming transverse centerline 21 and the hatch coaming longitudinal centerline 22 on the hatch coaming panel 2, and take the intersection of the hatch coaming transverse centerline 21 and the hatch coaming longitudinal centerline 22 as the origin of the hatch coaming coordinates.

[0052] S50. Draw the transverse center line and longitudinal center line of the reinforcement on the hatch coaming panel 2.

[0053] S60. Locate the theoretical positioning dimensions of the outfitting components using the origin of the hatch coaming coordinates. Compare the dimensional deviations of the theoretical positioning dimensions of the outfitting components with the transverse centerline and longitudinal centerline of the reinforcing members. Adjust the actual installation position of the outfitting components and install them onto the hatch coaming panel 2.

[0054] Understandably, compared to the traditional method of waiting for hatch cover 1 to be formed and returned to the ship section before installing and positioning it and then welding the outfitting components, this solution marks the transverse and longitudinal center lines of the reinforcement on the hatch coaming panel 2. By comparing the theoretical positioning dimensions of the outfitting components with the deviations of the transverse and longitudinal center lines of the reinforcement, the actual installation dimensions of the outfitting components can be corrected. This effectively ensures the installation accuracy of the outfitting components, reduces the adjustment work after the outfitting components are installed, and the outfitting components can be directly installed on the hatch coaming panel 2 during the hatch cover 1 manufacturing process, effectively shortening the installation cycle of the hatch cover system.

[0055] Optionally, after step S60, the installation method of the ship's outfitting components further includes step 70, installation after the hatch cover 1 is formed:

[0056] S71. Draw a transverse center line 11 and a mating line 12 with a certain distance interval on the hatch cover 1. A separation seam is provided within the interval of the mating line 12.

[0057] S72. Hoist hatch cover 1 onto the ship, aligning the lateral centerline 11 of the hatch cover with the lateral centerline 21 of the hatch coaming, and adjust the separation seam to align with the longitudinal centerline 22 of the hatch coaming, thus completing the installation and positioning of hatch cover 1 in one go.

[0058] In addition, cargo hold forming frame lines 23 and hatch cover corner cross lines can be drawn on the hatch coaming panel 2. Cargo hold forming frame lines 23 are the outer perimeter lines of the hatch coaming panel 2, and hatch cover corner cross lines are the four included angle lines of the hatch coaming panel 2. Both cargo hold forming frame lines 23 and hatch cover corner cross lines are used for auxiliary calibration when installing and positioning hatch cover 1 to improve the installation accuracy of hatch cover 1. Of course, after the lines are drawn, the relevant spur points are marked at the intersection of the lines on the hatch coaming panel 2.

[0059] Preferably, in step S60, the installation method of the ship outfitting components further includes adjusting the position of the reinforcing member. Based on the deviation values ​​between the theoretical positioning dimensions of the outfitting component and the transverse and longitudinal centerlines of the reinforcing member, it is determined whether to adjust the position of the reinforcing member. When the deviation between the first reinforcing member 4 and the guide device 3 is too large, the first reinforcing member 4 is cut and beveled to ensure the connection strength between the hatch coaming panels. Simultaneously, the installation position of the first reinforcing member 4 is marked using the theoretical positioning coordinates of the guide device 3. The cut-off first reinforcing member 4 is aligned with the marked line and welded, and the new weld is re-ground to ensure the positional accuracy of the first reinforcing member 4, thereby ensuring the subsequent support of the first reinforcing member 4 for the guide device 3. Figure 1 and Figure 3 As shown, specifically, the outfitting component includes a guide device 3, which includes a fixing member 31 and a first adjusting block 32. The first adjusting block 32 is fixed to one side of the fixing member 31 along a first direction (the first direction is...). Figure 1 In the X direction), the reinforcing member below the guide device 3 is the first reinforcing member 4, the dimension of the first reinforcing member 4 in the X direction is t1, the dimension of the first adjusting block 32 in the X direction is T1, the theoretical positioning coordinates of the fixing member 31 are (Fx1, Fy1), the actual installation coordinates of the fixing member 31 are (Fx1′, Fy1′), the fixing member 31 is symmetrical about the first center line 311 on both sides in the X direction, and the perpendicular distance between the first center line 311 and the longitudinal center line 41 of the first reinforcing member in the X direction is δ1;

[0060] There is no need to adjust the position of the first reinforcing member 4 when δ1 meets the following conditions;

[0061] when At that time, Fx1′=Fx1, Fy1′=Fy1, and the guide device 3 is installed using the theoretical positioning coordinates of the guide device 3;

[0062] when hour, Adjust the actual installation coordinates of guide device 3 to install guide device 3;

[0063] when hour, Adjust the actual installation coordinates of guide device 3 to install guide device 3;

[0064] when At that time, |Fx1′-Fx1|=T1, |Fy1′-Fy1|=T1;

[0065] When δ1 meets the following conditions, the position of the first reinforcing member 4 needs to be adjusted to the theoretical positioning coordinate position of the guide device 3.

[0066] when hour, Adjust the actual installation coordinates of the guide device 3 to install the guide device 3.

[0067] It is understandable that the theoretical positioning dimensions of the outfitting components are based on the intersection of the vertically set transverse centerline 11 of the hatch cover and the longitudinal centerline of the hatch cover as the coordinate origin. The actual installation dimensions of the outfitting components are based on the coordinate origin of the hatch coaming. In this embodiment, two guide devices 3 are provided at intervals along the second direction on the hatch coaming panel 2 (the second direction is...). Figure 1 (in the Y direction), with one of the guide devices 3 in For example, when the fixing member 31 is further away from the origin of the hatch coaming coordinates relative to the longitudinal centerline of the first reinforcing member 4, the actual installation dimensions (Fx1′, Fy1′) of the fixing member 31 are: When the fastener 31 is closer to the origin of the hatch coaming coordinates than the longitudinal centerline of the first reinforcing member 4, the actual installation dimensions (Fx1′, Fy1′) of the fastener 31 are: Using the actual dimensions of the first reinforcing member 4 on the hatch coaming panel 2 as a benchmark, the theoretical installation dimensions of the guide device 3 are calibrated to improve the accuracy of the actual installation dimensions of the guide device 3.

[0068] Furthermore, such as Figure 4As shown, the outfitting also includes an anti-jump device 5, which includes two first support plates 51 spaced along an X-axis. The two ends of the two first support plates 51 are connected by a first connecting plate 52 and a second connecting plate 53 at their respective ends along the height direction. The first connecting plate 52, the second connecting plate 53, and the two first support plates 51 together form an anti-jump groove 54, which is used to limit the jumping of the hatch 1. It should be noted that in this embodiment, since the anti-jump device 5 is installed before the hatch 1, in order to allow the anti-jump shaft 8 fixedly connected to the side of the hatch 1 to be smoothly inserted into the anti-jump groove 54, the second connecting plate 53 is detachably connected to the first support plate 51. The second connecting plate 53 is located on the side of the first connecting plate 52 away from the hatch 1. For example, one end of the second connecting plate 53 is rotatably connected to one of the first support plates 51, and the other end of the second connecting plate 53 is connected to another first support plate 51 through a locking structure. The locking structure can be a bolt 10, that is, the second connecting plate 53 has a through hole, and the first support plate 51 has a threaded hole. The bolt 10 passes through the through hole and is screwed into the threaded hole to fix the second connecting plate 53 and the first support plate 51. When the hatch cover 1 is installed, the bolt 10 is unscrewed and the second connecting plate 53 is rotated so that the anti-jump shaft 8 is inserted into the anti-jump groove 54.

[0069] Specifically, the two first support plates 51 are symmetrical about the second center line 55 along the X direction. The reinforcing member below the anti-jump device 5 is the second reinforcing member 6. The dimension of the second reinforcing member 6 along the X direction is t2. The distance between the second center line 55 and the first support plate 51 is T2. The theoretical positioning coordinates of the anti-jump device 5 are (Fx2, Fy2). The actual installation coordinates of the anti-jump device 5 are (Fx2′, Fy2′). The distance between the second center line 55 and the longitudinal center line 61 of the second reinforcing member along the X direction is δ2.

[0070] There is no need to adjust the position of the second reinforcing member 6 when δ2 meets the following conditions;

[0071] when At that time, Fx2′=Fx2, Fy2′=Fy2, and the anti-jump device 5 is installed using the theoretical positioning coordinates of the anti-jump device 5;

[0072] when hour, Adjust the actual installation coordinates of the anti-jump device 5 in order to install the anti-jump device 5;

[0073] when hour, Adjust the actual installation coordinates of the anti-jump device 5 in order to install the anti-jump device 5;

[0074] when At that time, |Fx2′-Fx2|=T2, |Fy2′-Fy2|=T2, adjust the actual installation coordinates of the anti-jump device 5 to install the anti-jump device 5;

[0075] When δ2 meets the following conditions, the position of the second reinforcing member 6 needs to be adjusted to the theoretical positioning coordinate position of the anti-jump device 5.

[0076] when hour, Adjust the actual installation coordinates of the anti-jump device 5 to install the anti-jump device 5.

[0077] For example, with anti-jump device 5 in For example, when the second centerline 55 is further away from the origin of the hatch coaming coordinates relative to the longitudinal centerline of the second reinforcing member 6, the actual installation dimensions (Fx2′, Fy2′) of the anti-jump device 5 are: When the second centerline 55 is closer to the origin of the hatch coaming coordinates than the longitudinal centerline of the second reinforcing member 6, the actual installation dimensions (Fx2′, Fy2′) of the anti-slip device 5 are: By using the actual dimensions of the second reinforcing member 6 on the hatch coaming panel 2 as a benchmark, the theoretical installation dimensions of the anti-jump device 5 are calibrated to improve the accuracy of the actual installation dimensions of the anti-jump device 5.

[0078] Furthermore, such as Figure 4 , Figure 5 and Figure 6As shown, the anti-jump device 5 also includes a sealing assembly 7 and an anti-jump shaft 8. The sealing assembly 7 includes a mounting bracket 71, a glue groove 72, and a glue strip 73. The mounting bracket 71 and the anti-jump shaft 8 are spaced apart on one side of the hatch cover 1. The glue groove 72 is located below the mounting bracket 71 and abuts against the hatch coaming panel 2 through the glue strip 73. The anti-jump shaft 8 is inserted into the anti-jump groove 54. The second connecting plate 53 is set away from the hatch coaming panel 2 relative to the first connecting plate 52. The installation height Fz1 of the second connecting plate 53 is calculated using Fz1 = H3 - H2 + G1 + H1 - C, where H3 is the flatness of the top side of the anti-jump shaft 8 measured relative to the reference line 9, H2 is the flatness of the glue groove 72 adjacent to the glue strip 73 measured relative to the reference line 9, G1 is the theoretical gap between the anti-jump shaft 8 and the second connecting plate 53, H1 is the original dimension of the glue strip 73 along the height direction, and C is the compression amount when the glue strip 73 is pressed deep relative to the reference line 9. In this embodiment, the installation height of the second connecting plate 53 is calculated using Fz1 = H3 - H2 + G1 + H1 - C. If Fz1 is too high, the bottom end of the first support plate 51 is appropriately trimmed to reduce the height of the second connecting plate 53, thus meeting the blocking requirements of the anti-jump shaft 8. It should be noted that the adhesive strip 73 is arranged around the hatch coaming panel 2 to seal the hatch cover 1 and the hatch coaming panel 2. In addition, C represents the compression amount when the rubber strip 73 is pressed deep relative to the baseline 9, i.e., the compression amount of the rubber strip 73 at the specified anti-jump device 5. To further refine the compression value of the rubber strip 73 at the specified position, the average flatness of the rubber groove 72 and the average flatness of the hatch coaming panel 2 can be pre-calculated. The matching flatness of the rubber groove 72 is calculated by adding the flatness of the rubber groove 72 at the specified anti-jump device 5 position to the flatness of the hatch coaming panel 2 at the specified anti-jump device 5 position, subtracting the average flatness of the rubber groove 72, and then subtracting the average flatness of the hatch coaming panel 2. The maximum compression amount of the rubber strip 73 is recorded. The maximum compression amount of the rubber strip 73 minus the minimum flatness of the hatch coaming panel 2 is the average compression amount of the rubber strip 73. The compression amount of the rubber strip 73 at the specified anti-jump device 5 position is obtained by subtracting the matching flatness value of the rubber groove 72 from the average compression amount of the rubber strip 73.

[0079] Furthermore, such as Figure 5As shown, the sealing assembly 7 also includes a third connecting plate 74, a mounting base 75, and a second adjusting block. The third connecting plate 74 is disposed on the side of the mounting frame 71 away from the hatch cover 1. The third connecting plate 74 is connected to the hatch coaming panel 2 through the mounting base 75. A second adjusting block is disposed between the third connecting plate 74 and the mounting base 75 or between the mounting base 75 and the hatch coaming panel 2. The thickness Z of the second adjusting block is calculated using Z = H4 - H2 + H1 - C, where H4 is the flatness of the side of the third connecting plate 74 adjacent to the hatch coaming panel 2 measured relative to the reference line 9. Specifically, the third connecting plate 74 is connected to the mounting base 75 via bolts 10. Based on the calculation result Z = H4 - H2 + H1 - C, the second adjusting block is an adjusting shim or adjusting pad. The number of adjusting shims or the appropriate thickness of adjusting pads are determined according to the calculation result. When Z < 6mm, adjusting shims are placed between the third connecting plate 74 and the mounting base 75, and the mounting base 75 is welded to the hatch coaming panel 2. When Z ≥ 6mm, adjusting pads are placed between the mounting base 75 and the hatch coaming panel 2, and the adjusting pads are welded to both sides of the mounting base 75 and the hatch coaming panel 2 along the height direction. The adjusting shim thickness is 2mm, and the gap between the third connecting plate 74 and the mounting base 75 cannot exceed 6mm to avoid relative sliding of multiple adjusting shims during use, thereby preventing instability in the installation of the hatch cover 1. By setting adjusting shims or adjusting pads, the connection gap between the third connecting plate 74 and the mounting base 75 meets the installation standards, preventing instability such as shaking or displacement of the hatch cover 1.

[0080] Optionally, the sealing assembly 7 also includes a clamping block. When C ≤ 18 mm, and 6 mm < C ≤ 18 mm, the rubber strip 73 directly abuts against the hatch coaming panel 2. When C ≤ 6 mm, a clamping block is installed between the rubber strip 73 and the hatch coaming panel 2, and the clamping block is welded to the hatch coaming panel 2.
