Description

Technical Field

[0001] This utility model belongs to the field of shipbuilding technology, and more specifically, it relates to a slipway half-ship sliding structure. Background Technology

[0002] In shipbuilding technology, ships need to be built on slipways. However, slipway construction is costly, and when shipbuilding demand is high, slipways cannot meet the needs. Currently, shipyards often use one slipway per ship, with the slipway length exceeding the ship's length, resulting in excess slipway space being idle and wasting shipyard output. Existing technologies do not utilize this idle space.

[0003] Existing technology includes a "steel structure slide for slipway launching," with publication (announcement) number "CN102530201B." This technology relates to a steel structure slide for slipway launching, which is composed of several steel structure slide units connected end-to-end. Each steel structure slide unit includes: a slide panel with multiple longitudinally arranged guide strips, forming guide grooves between two guide strips for ball bearing movement; reinforcing longitudinal ribs and longitudinal girder below the panel along the ball bearing movement trajectory; left and right side plates welded and fixed to the left and right sides of the slide panel; front and rear end plates welded and fixed to the front and rear ends of the slide panel; and a bottom anti-tilting plate welded and fixed to the left and right side plates, longitudinal girder, crossbeams, and front and rear end plates. Multiple transverse beams for reinforcement are also provided between the slide panel and the bottom anti-tilting plate. This invention combines the advantages of being lightweight, simple, flow-resistant, mud-resistant, safe, and easy to manufacture, making ship launching operations simple, increasing load-bearing capacity, reducing costs, and avoiding environmental pollution. However, this technology does not address the technical issues and solutions of this application. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a simple structure that can effectively improve the utilization rate of the slipway, solve the problem of tight slipway schedule in shipyards, effectively utilize idle resources, and improve the efficiency of shipbuilding.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: This utility model is a half-ship sliding structure on a slipway. The length of the slipway is greater than the length of the ship to be built. The space where the slipway is greater than the ship to be built is an unused space. A slideway is set in the unused space. A launching beam is set on the slideway. Multiple launching beams are set at intervals. The launching beams are fixedly connected to the half-ship hull. Multiple modular trolleys are set on one side of the slideway and multiple modular trolleys are set on the other side of the slideway.

[0006] The slide includes a first slide and a second slide, which are arranged in parallel. One end of the water-draining beam is supported on the first slide, and the other end of the water-draining beam is supported on the second slide.

[0007] The multiple modular trolleys outside the first slide rail are called first modular trolleys, and the multiple modular trolleys outside the second slide rail are called second modular trolleys. The multiple first modular trolleys are arranged in a straight line, and the multiple second modular trolleys are arranged in a straight line.

[0008] The first module trolley outside the first slideway is supported by a bracket on one side of the half-hull at the ship's side, and the second module trolley outside the second slideway is supported by a bracket on the other side of the half-hull at the ship's side.

[0009] An intermediate module trolley is set between the first and second slide rails.

[0010] Multiple anti-slip devices are installed at intervals in the aforementioned unused space.

[0011] The intermediate module trolley is arranged parallel to the slide rail.

[0012] The launching beam is supported on one side of the half-hull by a bracket, and the launching beam is supported on the other side of the half-hull by a bracket.

[0013] The upper end of the bracket on the side of the launching beam is welded to the ship's side, and the lower end of the bracket on the side of the launching beam is welded to the launching beam.

[0014] The upper end of the bracket on the outer side of the first slideway is welded to the side of the half-hull, and the lower end of the bracket on the outer side of the first slideway is supported on the first module trolley. The upper end of the bracket on the outer side of the second slideway is welded to the side of the other half-hull, and the lower end of the bracket on the outer side of the second slideway is supported on the second module trolley.

[0015] The working principle and beneficial effects of this utility model are as follows: The present invention describes a slipway half-hull sliding structure. When the slipway structure is set up, its length is greater than the length of the vessel to be built. The portion of the slipway exceeding the length of the vessel is unused space. To address the problems in existing technologies, this unused space is utilized. While building one vessel on the slipway, a partial structure (half-hull) of another vessel can be built in the unused space, thus fully utilizing the unused space and improving shipbuilding efficiency. A slipway is set in the unused space for the subsequent sliding of the half-hull. A launching beam is installed on the slipway, and the launching beam is fixedly connected to the half-hull, serving to support the half-hull and reliably support it. Multiple launching beams are set at intervals and are fixedly connected to the half-hull. Multiple modular trolleys are set on one side of the slipway and multiple modular trolleys are set on the other side. The modular trolleys on both sides are respectively connected to and support the corresponding sides of the half-hull, reliably supporting the half-hull and preventing it from capsizing. After a vessel is completed and launched on the slipway, half of its hull is slid towards the waterline to continue construction. The unused space can be used for the construction of partial structures of another vessel, and so on. In this way, a slipway of the same length, which could only store and build one vessel in a certain cycle, can now store and build 1.5 vessels, effectively solving the problem of insufficient cycle time of the original slipway.

[0017] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part: As attached Figure 1 - Appendix Figure 3As shown, this utility model is a half-ship sliding structure on a slipway. The slipway length is greater than the length of the ship to be built. The portion of the slipway longer than the ship is considered an idle space 1. A slideway 2 is set in the idle space 1, and a launching beam 3 is set on the slideway 2. Multiple launching beams 3 are arranged at intervals and are fixedly connected to the half-ship hull 9. Multiple modular trolleys are set on one side of the slideway 2, and multiple modular trolleys are set on the other side of the slideway 2. This structure addresses the shortcomings of existing technologies by proposing an improved technical solution. When setting up the slipway structure, the slipway length is greater than the length of the ship to be built, and the portion of the slipway longer than the ship is considered an idle space 1. To solve the problems in existing technologies, this idle space is utilized. While building one ship on the slipway, the idle space can be used to build a partial structure (half-ship hull 9) of another ship, thus making full use of the idle space and improving ship construction efficiency. A slideway 2 is installed in the idle space 1. Slideway 2 is used for the later sliding of the half-hull 9. A launching beam 3 is installed on slideway 2, and the launching beam 3 is fixedly connected to the half-hull 9. It is used to support the half-hull 9 and to reliably support it on the launching beam 3. Multiple launching beams 3 are set at intervals. Multiple modular trolleys are set on one side of slideway 2 and multiple modular trolleys are set on the other side of slideway 2. The modular trolleys on both sides are respectively connected to the corresponding sides of the half-hull 9 to reliably support the half-hull 9 and prevent it from capsizing. After the ship in front of the slipway is completed and launched, the half-hull of the ship is slid towards the waterline to continue construction. The idle space can be used for the construction of a partial structure (half-hull 9) of another ship, and so on. In this way, the slipway of the same length, which can only store and build one ship in a certain cycle, can now store and build 1.5 ships, effectively solving the problem of insufficient cycle time of the original slipway. The slipway semi-sliding structure described in this utility model has a simple structure, can effectively improve the slipway utilization rate, solve the problem of tight slipway schedules in shipyards, effectively utilize idle resources, and improve shipbuilding efficiency.

[0018] The aforementioned slide 2 includes a first slide 4 and a second slide 5, which are arranged in parallel. One end of the launching beam 3 is supported on the first slide 4, and the other end is supported on the second slide 5. With this structure, the two slides can reliably be used for the launching beam arrangement, meeting the load-bearing requirements during the construction of the half-hull 9, and can be reliably used for the sliding of the half-hull 9 later. The launching beam 3 has a protruding lower section, preventing it from sliding off the slide and instead driving the half-hull 9 to move linearly along the direction of the slide.

[0019] The multiple modular trolleys outside the first slideway 4 are designated as first modular trolleys 10, and the multiple modular trolleys outside the second slideway 2 are designated as second modular trolleys 11. The first modular trolleys 10 and 11 are arranged in a straight line. The first modular trolleys 10 outside the first slideway 4 are supported by brackets 6 on one side of the hull 9 at the ship's side 7, and the second modular trolleys 11 outside the second slideway 5 are supported by brackets 6 on the other side of the hull 9 at the ship's side 7. Because the hull 9 has a certain width, to prevent it from tipping over during construction, brackets 6 are welded to both sides of the hull 9. These brackets 6 are then supported by the modular trolleys, ensuring reliable support and good stability for the hull 9. When the hull 9 slides, the modular trolleys move synchronously. When the hull 9 is completed and ready for launch, the modular trolleys, equipped with hydraulic lifting cylinders, can retract and move away from the brackets. The connection between the brackets and the ship's side is then cut, and the hull is launched.

[0020] An intermediate module trolley 8 is installed between the first slide rail 4 and the second slide rail 5. In this configuration, the intermediate module trolley 8 provides support from the middle during the construction of the half-hull 9.

[0021] Multiple anti-slip devices are installed at intervals in the aforementioned unused space 1. In this structure, during the construction of the half-hull 9, the anti-slip devices open to prevent the half-hull 9 from slipping. When the half-hull 9 slips, the anti-slip devices close, and a towing rope at the rear of the half-hull 9 slowly slides it into place.

[0022] The intermediate module trolley 8 is arranged parallel to the slideway 2. One side of the launching beam 3 is supported by a bracket 6 at the side 7 of the half-hull 9, and the other side of the launching beam 3 is also supported by a bracket 6 at the same location. The upper end of the bracket 6 on the side of the launching beam 3 is welded to the side 7, and the lower end of the bracket 6 on the side of the launching beam 3 is welded to the launching beam 3. The upper end of the bracket 6 on the outer side of the first slideway 4 is welded to the side 7 of the half-hull 9, and the lower end of the bracket 6 on the outer side of the first slideway 4 is supported on the first module trolley. The upper end of the bracket 6 on the outer side of the second slideway 5 is welded to the other side 7 of the half-hull 9, and the lower end of the bracket 6 on the outer side of the second slideway 5 is supported on the second module trolley.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
