Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, and in particular to a guide structure for container ship hatch covers. Background Technology

[0002] Container ships have become one of the world's three major transport vessel types (tankers, bulk carriers, and container ships). Besides bulk cargo, global trade relies heavily on container ship transport. To save costs and increase capacity, the demand for larger container ships is increasingly strong. Large container ships are high-tech, high-value-added vessels and are currently one of the key ship types being developed globally. After decades of development, the form of container lashing bridges has gradually become standardized and mature. Current designs often fully consider the cargo hold structure, hatch covers, and lashing bridge design, allowing for flexible and versatile loading of refrigerated containers, dangerous goods containers, standard containers, high cube containers, and European standard containers. The guide structure for container ship hatch covers must ensure the accuracy of the gap between the hatch cover and the lashing bridge during lifting. Existing technologies mainly have the following problems:

[0003] (1) Waste of materials and time: The guide column is welded with continuous plates on three sides from top to bottom. The utilization rate of the plates is low, and the steel consumption per ship increases.

[0004] (2) Low installation efficiency: It is necessary to repeatedly hoist the hatch cover to measure the gap and weld the adjustment plate on site, and the installation of a single hatch cover takes a long time;

[0005] (3) Structural redundancy: The side panels and the hatch adjustment panel have overlapping functions, resulting in insufficient maintenance space.

[0006] The aforementioned problems lead to increased construction costs and extended construction periods. Therefore, this utility model proposes a container ship hatch cover guide structure to achieve material savings and improved installation efficiency. Summary of the Invention

[0007] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a container ship hatch cover guide structure. Through the innovative design of intermittent single-sided anti-wear plate and overall adjustment plate, it solves the technical problems of material waste, low welding efficiency and complicated installation of traditional guide structures.

[0008] The purpose of this utility model is achieved as follows:

[0009] A container ship hatch cover guide structure is provided between the hatch cover and the guide column. The side of the hatch cover is provided with a U-shaped guide groove. The U-shaped guide groove includes a horizontal plate and vertical plates arranged at both ends of the horizontal plate. The horizontal plate is fitted onto the hatch cover. Each vertical plate is provided with a diagonal brace on its outer side. One end of the diagonal brace is fixed to the outer wall of the vertical plate, and the other end is fixed to the hatch cover.

[0010] The inner walls of the horizontal and vertical plates are respectively provided with an integral adjustment plate: a first adjustment plate, a second adjustment plate and a third adjustment plate. The first adjustment plate is attached to the inner wall of the horizontal plate, and the second and third adjustment plates are attached to the inner walls of the vertical plates on both sides, respectively.

[0011] The U-shaped guide groove has a guide column in the groove direction, and the left end of the guide column is embedded in the U-shaped guide groove, that is, the front of the guide column faces the first adjusting plate in the groove of the U-shaped guide groove.

[0012] The guide column has an anti-abrasion plate on the side near the hatch, and the anti-abrasion plate is intermittently arranged at the position of the binding eye plate and each layer of railing.

[0013] Furthermore, the first, second, and third adjusting plates are integrally formed and welded to the inner walls of the horizontal and vertical plates, with an adjustable thickness of 10-50mm.

[0014] Furthermore, the anti-wear plate has a thickness of 15mm and a length of 800mm.

[0015] Furthermore, the distance between the anti-wear plate and the first adjusting plate is 20mm.

[0016] Furthermore, the distance between the two sides of the guide column and the corresponding second or third adjusting plate is 17±5mm.

[0017] Furthermore, the diagonal brace is inclined at 45° to connect the outer wall of the vertical plate and the hatch.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This utility model provides a container ship hatch cover guide structure. Through the coordinated design of the intermittent patch on the front of the guide column and the overall adjustment plate of the hatch cover, it achieves reduced material usage, improved installation efficiency, and a gap accuracy of ±2mm. This structure significantly reduces shipbuilding costs and construction time. This utility model has the following advantages:

[0020] (1) Material saving: The amount of lining plates used is reduced, saving the cost of steel per ship;

[0021] (2) Improved work efficiency: Welding time is reduced by about half, and the hatch cover installation cycle is greatly shortened;

[0022] (3) Precision assurance: The overall adjustment plate eliminates the assembly error of the separate parts, and the gap control accuracy reaches ±2mm;

[0023] (4) Easy maintenance: The single-sided design expands the maintenance space of the ties bridge. Attached Figure Description

It should be understood that the specific embodiments described below are not intended to limit the specific implementation of the technical solution of this utility model, but are merely possible implementations of the technical solution of this utility model. It should be noted that the descriptions of the positional relationships of the components herein, such as component A being located above component B, are based on the relative positions of the components in the illustrations and are not intended to limit the actual positional relationships of the components. Example 1

[0029] See Figure 1-2 , Figure 1 A schematic diagram of a container ship hatch cover guide structure according to Embodiment 1 is shown. As shown in the figure, the container ship hatch cover guide structure according to Embodiment 1 is disposed between the hatch cover 1 and the guide column 2. A U-shaped guide groove 3 is provided on the side of the hatch cover 1. The U-shaped guide groove 3 includes a horizontal plate 3.1 and vertical plates 3.2 vertically disposed at both ends of the horizontal plate 3.1. The horizontal plate 3.1 is fitted onto the hatch cover 1. Each vertical plate 3.2 has a diagonal brace 4 on its outer side. One end of the diagonal brace 4 is fixed to the outer wall of the vertical plate 3.2, and the other end is fixed to the hatch cover 1.

[0030] The inner walls of the horizontal plate 3.1 and the vertical plate 3.2 are each provided with an integral adjusting plate: a first adjusting plate 5, a second adjusting plate 6, and a third adjusting plate 7. The first adjusting plate 5 is attached to the inner wall of the horizontal plate 3.1, and the second adjusting plate 6 and the third adjusting plate 7 are attached to the inner walls of the vertical plates 3.2 on both sides, respectively. The first adjusting plate 5, the second adjusting plate 6, and the third adjusting plate 7 are integrally formed and welded to the inner walls of the horizontal plate 3.1 and the vertical plate 3.2, and their thickness is adjustable from 10 to 50 mm.

[0031] The U-shaped guide groove 3 has a guide column 2 in the groove direction. The left end of the guide column 2 is embedded in the U-shaped guide groove 3, that is, the front of the guide column 2 faces the first adjusting plate 5 in the groove of the U-shaped guide groove 3.

[0032] The guide column 2 has an anti-wear plate 8 on the side of the front of the hatch 1. The anti-wear plate 8 is intermittently arranged at the position of the binding eye plate and each layer of railing, with a thickness of 15mm and a length of 800mm.

[0033] The guide column 2 has no side panels, which saves materials and expands the operating space.

[0034] The distance between the anti-wear plate 8 and the first adjusting plate 5 is 20mm; the distance between the two sides of the guide column 2 and the corresponding second adjusting plate 6 or third adjusting plate 7 is 17±5mm.

[0035] The diagonal brace 4 is inclined at 45° to connect the outer wall of the vertical plate and the hatch cover, thereby enhancing its resistance to deformation.

[0036] Working principle:

[0037] This utility model provides a container ship hatch cover guide structure, including the following installation and workflow;

[0038] (1) Installation process:

[0039] 1. Pre-treatment of lashed bridges:

[0040] Abrasion-resistant plates are welded to the front of the guide posts, covering only the corresponding areas of the binding eye plates and railings;

[0041] 2. Hatch cover assembly:

[0042] The overall adjusting plate is welded to the inner wall of the U-shaped guide groove;

[0043] Install diagonal bracing to reinforce the U-shaped guide groove;

[0044] 3. On-site assembly:

[0045] Hoist the hatch cover so that the left end of the guide column is embedded in the U-shaped groove;

[0046] Check the distance between the anti-wear plate and the adjustment plate (20mm), and the distance between the side of the column and the vertical plate (17±5mm).

[0047] (2) Workflow:

[0048] 1. When the hatch cover is lifted vertically, the overall adjusting plate and the anti-abrasion plate form a sliding guide surface; the hatch cover is lifted vertically, and the anti-abrasion plate is set to prevent the hatch cover from directly rubbing against the guide column of the lashing bridge.

[0049] 2. The single-sided discontinuous design avoids interference with the protrusions of the tying bridge and reduces the friction area.

[0050] This utility model achieves a breakthrough by combining the improvements of "intermittent mounting plate + single-sided layout" and "overall adjustment plate transfer welding":

[0051] (1) Material redundancy: Only key stress points are covered with plates to eliminate invalid coverage areas;

[0052] (2) Installation bottleneck: The overall adjustment plate is welded in one go in the dock, avoiding repeated hoisting of the hatch cover;

[0053] (3) Loss of precision control: 17±5mm gap standardized design replaces on-site repair.

[0054] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
