Description

Technical Field

[0001] This invention relates to the field of marine engineering technology, and more specifically, to a ship launching system. Background Technology

[0002] In traditional ship launching operations, modular vehicle ramps are typically constructed using monolithic concrete casting. When a ship descends the ramp along the downhill track, the hull is highly susceptible to physical interference with the edge of the platform at the ramp's front. To mitigate this risk, the entire hull must be raised significantly, necessitating a longer launching ramp to ensure the ship can float smoothly upon entering the water. Simultaneously, the modular vehicle's lifting mechanism needs a greater vertical travel range to accommodate adjustments in hull height, and the support height of the hull support pads must also be increased accordingly. These design flaws not only significantly increase construction difficulty and material costs but also reduce stability during launching, increasing operational risks and impacting overall operational efficiency and safety. Summary of the Invention

[0003] The purpose of this invention is to provide a ship launching system that can reduce the initial height of the ship launch, thereby shortening the descent length of the slipway, saving the construction cost of the slipway system, reducing the lifting stroke requirements of the modular vehicle, and reducing the amount of padding material between the inclined frame and the bottom of the ship.

[0004] This invention provides a ship launching system, comprising: modular vehicles, modular vehicle channels, downhill tracks, transition supports, and downhill inclined ship frames; multiple modular vehicle channels are arranged at intervals, and each modular vehicle channel has a corresponding transition support at its front end; multiple modular vehicles are used to jointly carry a ship from its corresponding modular vehicle channel to the transition support; multiple downhill tracks and multiple modular vehicle channels are arranged alternately, and each downhill track has a corresponding downhill inclined ship frame; the modular vehicles are used to transfer the ship to the multiple downhill inclined ship frames, and the multiple downhill inclined ship frames are used to move together along the multiple downhill tracks to transfer the ship from the downhill tracks to underwater; the transition support has a horizontal support state and an inclined retracted state; when the ship is on the modular vehicle, the transition support is in the horizontal support state to support the modular vehicle; when the ship is on the downhill inclined ship frame, the transition support is in the inclined retracted state to avoid interference between the ship and the transition support when the ship is descending.

[0005] Optionally, a lower foundation is provided below the transition support, and one end of the transition support near the modular vehicle channel is hinged to the lower foundation. The transition support is used to rotate around the hinge point between the transition support and the lower foundation to switch between the horizontal support state and the tilted and folded state.

[0006] Optionally, the transition support includes a main beam, a vertical fixed beam, and a horizontal rotating beam. The main beam is used to support the modular vehicle. The vertical fixed beam is connected to the lower part of the main beam. The horizontal rotating beam is rotatably connected to the end of the vertical fixed beam away from the main beam via a rotating beam pin. A foundation pit is provided on the lower foundation to accommodate the horizontal rotating beam. The length of the horizontal rotating beam is greater than the width of the foundation pit. When the transition support is in a horizontal support state, at least a portion of the horizontal rotating beam is supported on the upper surface of the foundation pit. When the transition support is in an inclined and retracted state, at least a portion of the horizontal rotating beam is accommodated in the foundation pit.

[0007] Optionally, a plurality of vertical fixed beams are arranged at intervals below the main beam along the length direction of the main beam, and a horizontal rotating beam is correspondingly provided at the end of each vertical fixed beam away from the main beam, and a plurality of foundation pits for accommodating the horizontal rotating beam are correspondingly provided on the lower foundation.

[0008] Optionally, an upper hinge seat is provided at one end of the main beam near the modular vehicle passage, and a lower hinge seat is provided on the lower foundation. The upper hinge seat and the lower hinge seat are connected by a hinge seat pin.

[0009] Optionally, the launching system of this vessel also includes a downhill traction mechanism, with each downhill inclined frame corresponding to one downhill traction mechanism, which is used to drive the downhill inclined frame to move along the corresponding downhill track.

[0010] Optionally, a shim is provided on the downslope gantry to keep the vessel on the downslope gantry in a horizontal position.

[0011] Optionally, the slope of the downhill track is 1:7.

[0012] Optionally, multiple downhill inclined boat frames are arranged alternately on the corresponding downhill tracks.

[0013] Optionally, the modular vehicle is equipped with a lifting mechanism, which is used to lift the ship.

[0014] The ship launching system provided by this invention has, but is not limited to, the following beneficial effects compared to existing technologies: The ship launching system described in this invention first involves a ship transfer operation. The transition supports are in a horizontal support state, and multiple modular vehicles jointly carry the ship from multiple modular vehicle channels to multiple transition supports. Then, the ship is lowered onto multiple downward-sloping inclined ship frames via the multiple modular vehicles. After the modular vehicles disengage from the ship, they are withdrawn. Next, the ship descends. Before this, the transition supports are switched from a horizontal support state to an inclined and retracted state. Multiple downward-sloping inclined ship frames jointly carry the ship from multiple downward-sloping tracks into the water. Once the ship floats in the water, the downward-sloping inclined ship frames are withdrawn. Thus, when the ship is on a modular vehicle, the transition supports are in a horizontal support state to support the modular vehicle; when the ship is on a downward-sloping ship frame, the transition supports are in an inclined and retracted state, thereby avoiding interference between the ship and the transition supports during descent. This state switching mechanism solves the problem of interference between the ship's bottom and the front end of the modular vehicle channel during descent, reduces the ship's lifting height, shortens the slide length, reduces the modular vehicle lifting stroke, and lowers the bottom jacking height.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0021] Furthermore, in the attached diagram, the X-axis represents the horizontal direction, that is, the left and right position, with the positive direction of the X-axis representing the left and the negative direction of the X-axis representing the right; the Y-axis represents the vertical direction, that is, the front and back position, with the positive direction of the Y-axis representing the front and the negative direction of the Y-axis representing the back; and the Z-axis represents the vertical direction, that is, the up and down position, with the positive direction of the Z-axis representing the up and the negative direction of the Z-axis representing the down.

[0022] It should also be noted that the aforementioned X-axis, Y-axis and Z-axis are used only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0023] In traditional ship launching operations, the modular vehicle channel uses a fixed concrete structure, with its front platform positioned in a fixed and non-adjustable position. During the ship's descent, spatial interference occurs between the hull structure and the front platform of the modular vehicle channel, necessitating the hull to be raised to a higher position to avoid physical contact. This problem directly increases the required hull lifting height, extends the slide length, expands the modular vehicle's lifting range, and increases the height of the hull's bottom support, affecting the stability of the launching operation and the overall efficiency of the system.

[0024] For example, in the launching operation of large container ships, the modular vehicle channel is formed by concrete pouring, with a fixed platform at the front. When multiple modular vehicles jointly carry the ship and move along the modular vehicle channel, the keel area of ​​the hull approaches the fixed platform at the front of the channel. To avoid collision between the hull and the platform, the hull is lifted to a height exceeding the design specifications. Therefore, the length of the slideway needs to be extended accordingly to ensure the ship reaches the buoyancy condition at the predetermined position. Simultaneously, the lifting stroke of the modular vehicles must cover a larger area, and the height of the hull support pads must be increased accordingly. This process increases the complexity of system operation and may cause difficulties in adjusting the ship's attitude.

[0025] If the above problems are not resolved, spatial interference will persist during the ship's descent, preventing an effective reduction in the hull's lifting height. This necessitates further increases in the length of the slipway to meet buoyancy requirements, limits the lifting range of the modular vehicle, and maintains a relatively high hull-side pad height. Furthermore, increased system design redundancy raises operational risks and may affect the ship's dynamic stability during launching, thus posing challenges to operational safety and reliability.

[0026] Therefore, such as Figures 1 to 5 As shown, the present invention provides a ship launching system, comprising: modular vehicles 1, modular vehicle channels 2, downhill tracks 3, transition supports 4, and downhill inclined ship frames 5; multiple modular vehicle channels 2 are arranged at intervals, and each modular vehicle channel 2 has a corresponding transition support 4 at its front end; multiple modular vehicles 1 are used to jointly carry a ship 100 from its corresponding modular vehicle channel 2 to the transition support 4; multiple downhill tracks 3 are arranged alternately with multiple modular vehicle channels 2, and each downhill track 3 has a corresponding downhill inclined ship frame 5; the modular vehicles 1 are used to launch the ship 100. The vessel 100 is transferred to multiple downhill inclined boat frames 5, which are used to move together along multiple downhill tracks 3 to transfer the vessel 100 from the downhill tracks 3 to the water. The transition support 4 has a horizontal support state and an inclined retracted state. When the vessel 100 is on the module vehicle, the transition support 4 is in the horizontal support state to support the module vehicle 1. When the vessel 100 is on the downhill inclined boat frame 5, the transition support 4 is in the inclined retracted state to avoid interference between the vessel 100 and the transition support 4 when the vessel 100 is descending.

[0027] In this embodiment, in conjunction with the appendix Figure 1 To be continued Figure 5As shown, firstly, the ship transfer operation is carried out. The transition support 4 is in a horizontal support state. Multiple modular vehicles 1 jointly carry the ship 100 from multiple modular vehicle channels 2 to multiple transition supports 4. Then, the ship 100 is lowered onto multiple downhill inclined ship frames 5 by multiple modular vehicles 1. After the multiple modular vehicles 1 are no longer in contact with the ship 100, they are withdrawn. Secondly, the ship descent operation is carried out. Before this, the transition support 4 is switched from a horizontal support state to an inclined and retracted state. Multiple downhill inclined ship frames 5 jointly carry the ship 100 from multiple downhill tracks 3 into the water. After the ship floats in the water, the downhill inclined ship frames 5 are withdrawn. Thus, when the ship 100 is on the modular vehicle 1, the transition support 4 is in a horizontal support state to support the modular vehicle 1. When the ship 100 is on the downhill inclined ship frame 5, the transition support 4 is in an inclined and retracted state, thereby avoiding interference between the ship 100 and the transition support 4 when descent. This state switching mechanism solves the problem of interference between the ship's bottom and the front end of the modular vehicle channel when the ship is going downstream, reducing the lifting height of the hull, shortening the slide length, reducing the lifting stroke of the modular vehicle, and reducing the height of the bottom pad.

[0028] It should be noted that the modular vehicle 1 can specifically be an electrically driven self-propelled modular transport vehicle, whose carrying platform adopts a standardized design to adapt to ships of different sizes.

[0029] Optionally, a lower base 6 is provided below the transition support 4, and one end of the transition support 4 near the module vehicle channel 2 is hinged to the lower base 6. The transition support 4 is used to rotate around the hinge point between the transition support 4 and the lower base 6 to switch between the horizontal support state and the tilted and folded state.

[0030] In this embodiment, in conjunction with the appendix Figure 4 and attached Figure 5 As shown, the lower foundation 6 refers to the structure that serves as a stable support base, which can be made of concrete or steel, and its purpose is to provide a fixed rotation axis reference. The transition bracket 4 is hinged to the lower foundation 6 at one end near the modular vehicle channel 2, which means that the fixed end is rotatably connected through a rotating connection mechanism, which can be implemented by a pin connection, and its purpose is to simplify the state switching mechanism. The transition bracket 4 rotates around the hinge point to switch between a horizontal support state and an inclined folding state, which means that the state transition is completed by rotation, which can be achieved manually or with the help of external force, and its purpose is to quickly make room for downward movement and avoid interference.

[0031] Specifically, the lower foundation 6 is fixed to the ground, and the transition support 4 is connected to the lower foundation 6 at one end near the modular vehicle passage 2 via a hinge point, allowing the transition support 4 to rotate around this hinge point. When the vessel 100 is on the modular vehicle 1, the transition support 4 maintains a horizontal support state to support the modular vehicle 1; when the vessel 100 is transferred to the downhill inclined frame 5, the transition support 4 rotates around the hinge point to a tilted and retracted state, thereby avoiding interference with the downstream vessel 100. This structural design achieves state switching through a simple rotational movement, ensuring the continuity and safety of the launching process.

[0032] Optionally, the transition support 4 includes a main beam 41, a vertical fixed beam 42, and a horizontal rotating beam 43. The main beam 41 is used to support the module vehicle 1. The vertical fixed beam 42 is connected to the lower part of the main beam 41. The horizontal rotating beam 43 is rotatably connected to the end of the vertical fixed beam 42 away from the main beam 41 via a rotating beam pin 44. A foundation pit 61 for accommodating the horizontal rotating beam 43 is provided on the lower foundation 6. The length of the horizontal rotating beam 43 is greater than the width of the foundation pit 61. When the transition support 4 is in a horizontal support state, at least part of the horizontal rotating beam 43 is supported on the upper surface of the foundation pit 61. When the transition support 4 is in an inclined and retracted state, at least part of the horizontal rotating beam 43 is accommodated in the foundation pit 61.

[0033] In this embodiment, in conjunction with the appendix Figure 4 To be continued Figure 7 As shown, the main beam 41 refers to the main structure of the transition support 4 that directly supports the module vehicle 1. It can be made of high-strength steel welded into an I-beam or box beam, with the purpose of providing a stable horizontal support platform. The vertical fixed beam 42 refers to the vertical support component connected below the main beam 41. It can be made of steel pipe or steel column, with the purpose of reliably transferring the load of the main beam 41 to the lower foundation 6. The horizontal rotating beam 43 refers to the rotatable component rotatably connected to the end of the vertical fixed beam 42 through the rotating beam pin 44. It can be made of solid steel beam or hollow rectangle. The purpose of this is to allow for independent angle adjustment when the structure is tilted and retracted. The foundation pit 61 refers to a recessed space created on the lower foundation 6 to accommodate the horizontal rotating beam 43. This can be achieved by excavating a pit or using a precast concrete trough, providing a dedicated area for the horizontal rotating beam 43. The fact that the length of the horizontal rotating beam 43 is greater than the width of the foundation pit 61 means that the horizontal rotating beam 43 can abut against the lower end face of the lower foundation 6. Rotating the horizontal rotating beam 43 by 90° allows it to be embedded into the foundation pit 61, thus completing the state switch. (See attached diagram.) Figure 6 and attached Figure 7 As shown.

[0034] Optionally, a plurality of vertical fixed beams 42 are arranged at intervals below the main beam 41 along the length direction of the main beam, and a horizontal rotating beam 43 is correspondingly provided at the end of each vertical fixed beam 42 away from the main beam 41, and a plurality of foundation pits 61 for accommodating the horizontal rotating beam 43 are correspondingly provided on the lower foundation 6.

[0035] In this embodiment, in conjunction with the appendix Figure 4 and attached Figure 5 As shown, multiple vertical fixed beams 42 are used along the length of the main beam 41 (see attached diagram). Figure 1 The load is distributed across multiple support units in the X-axis direction, based on the load-bearing span characteristics of the main beam 41. This ensures that the weight of the modular vehicle 1 carrying the ship 100 is evenly transferred to the lower foundation 6, preventing the main beam 41 from bending and deforming due to stress concentration. At the same time, the multiple foundation pits 61 opened on the lower foundation 6 provide dedicated accommodation areas for the spatial layout of the horizontal rotating beams 43, ensuring that each horizontal rotating beam 43 can be freely embedded in the tilted and retracted state, thereby ensuring the smooth transition of the transition support 4 from the horizontal support state to the tilted and retracted state.

[0036] Optionally, an upper hinge seat 71 is provided at one end of the main beam 41 near the modular vehicle passage 2, and a lower hinge seat 72 is provided on the lower foundation 6. The upper hinge seat 71 and the lower hinge seat 72 are connected by a hinge seat pin 73.

[0037] In this embodiment, in conjunction with the appendix Figure 5 As shown, the upper hinge seat 71 refers to the hinge component set at the end of the main beam 41. It can be made of cast steel or welded structure, and its purpose is to provide a stable rotation fulcrum to ensure that the main beam 41 rotates smoothly around the fixed axis when switching states. The lower hinge seat 72 refers to the hinge component fixed on the lower foundation 6. It can be made of embedded steel plate or concrete pouring structure, and its purpose is to form a stable rotation reference surface to prevent displacement or deformation under ship load. The hinge seat pin 73 refers to the shaft pin connecting the upper hinge seat 71 and the lower hinge seat 72. It can be made of high-strength alloy steel shaft or ball bearing structure, and its purpose is to reduce frictional resistance, ensure smooth rotation and minimize mechanical wear.

[0038] Specifically, the upper hinge 71 is fixed to the end of the main beam 41, the lower hinge 72 is anchored to the lower foundation 6, and the hinge pin 73 is configured to pass through the upper hinge 71 and the lower hinge 72 to form a rotating pair. When the vessel 100 is on the modular vehicle 1 and travels along the modular vehicle passage 2, the transition support 4 is in a horizontal support state, with the upper hinge 71, the lower hinge 72, and the hinge pin 73 jointly bearing the load of the modular vehicle 1. When the vessel 100 is transferred to the downhill inclined frame 5, the transition support 4 rotates around the hinge pin 73 to an inclined and retracted state. This rotation is achieved through the low-friction engagement of the hinge pin 73, ensuring that the transition support 4 retracts in time and avoids interference with the downstream vessel 100.

[0039] Optionally, the launching system of this vessel also includes a downhill traction mechanism 8, with each downhill inclined frame 5 corresponding to one downhill traction mechanism 8, which is used to drive the downhill inclined frame 5 to move along the corresponding downhill track 3.

[0040] In this embodiment, in conjunction with the appendix Figure 1 and attached Figure 3 As shown, the downhill traction mechanism 8 refers to the device that provides active traction force. It can be implemented by an electric winch, hydraulic motor or hoist. Its purpose is to replace the gravity sliding mode and realize active adjustment of the movement speed. Each downhill inclined boat frame 5 is equipped with a corresponding downhill traction mechanism 8, which can be understood as a one-to-one configuration. Its purpose is to ensure that each downhill inclined boat frame 5 can be independently controlled according to its own load status and track conditions, avoid mutual interference when multiple inclined boat frames move together, and thus improve the stability and adaptability of the movement.

[0041] Specifically, this solution uses a downhill traction mechanism 8 to actively move the downhill inclined boat frame 5 along the downhill track 3, replacing the traditional gravity-based descent mode. Each downhill inclined boat frame 5 is equipped with an independent downhill traction mechanism 8, allowing each downhill inclined boat frame 5 to adjust its traction force in real time according to the weight distribution of the vessel 100 and the local conditions of the downhill track 3, thereby precisely controlling its speed and position. This one-to-one configuration avoids dynamic coupling problems, ensuring that each downhill inclined boat frame 5 does not interfere with each other during movement. Furthermore, because the speed can be actively adjusted, there is no need to rely on a long downhill track 3 for safe deceleration, simplifying the system design.

[0042] As a preferred embodiment, the downhill traction mechanism 8 can be specifically an electric winch connected to the traction lug of the downhill inclined boat frame 5 via a high-strength steel wire rope; after the boat 100 is transferred to the downhill inclined boat frame 5, the electric winch is started to wind up and unwind the steel wire rope at an adjustable speed, driving the downhill inclined boat frame 5 to descend smoothly along the downhill track 3.

[0043] Optionally, a shim 51 is provided on the downhill inclined frame 5 to keep the vessel 100 located on the downhill inclined frame 5 in a horizontal state.

[0044] In this embodiment, in conjunction with the appendix Figure 3 As shown, the pad 51 refers to the support structure used to dynamically adjust the horizontal attitude of the ship 100. It can be implemented by using liftable mechanical pads, hydraulic support units or elastic buffer materials. Its purpose is to ensure that the ship maintains a stable horizontal attitude during movement by compensating for the tilting effect caused by the slope of the downhill track in real time, thereby reducing the excessive reliance on the lifting stroke of the module vehicle.

[0045] Specifically, this solution integrates the pad 51 on the downhill inclined frame 5. When the vessel 100 is transferred from the modular vehicle to the downhill inclined frame 5, the pad 51 provides adaptive support points according to the change of track slope, so that the center of gravity of the vessel 100 is evenly distributed, avoiding the potential interference risk between the bottom of the vessel and the transition support 4 caused by tilting. At the same time, it optimizes the lifting operation process of the modular vehicle 1 and simplifies the additional steps required for attitude adjustment in the traditional method.

[0046] As a specific implementation method, the pad 51 is actually a plurality of wedge-shaped adjustment blocks made of high-strength alloy steel, which are evenly distributed on the bearing surface of the downslope inclined frame 5. When the ship 100 is placed on it, the operator manually adjusts the insertion depth of each wedge block according to the ship's attitude in order to achieve precise horizontal positioning of the ship 100.

[0047] Optionally, the slope of the downhill track 3 is 1:7.

[0048] In this embodiment, the 1:7 gradient refers to the ratio of vertical height to horizontal distance. It can be achieved by combining elevation measurement and distance calibration during track construction. The purpose is to ensure that the ship's descent speed is within a safe and controllable range, avoiding the risk of loss of control due to an excessively steep gradient or the problem of excessive track length extension due to an excessively gentle gradient.

[0049] Specifically, when the downhill track 3 adopts a 1:7 gradient design, the acceleration of the ship 100 is precisely controlled within a reasonable range as it descends along the track under the action of gravity. This provides sufficient downward power to overcome track friction resistance and effectively suppresses potential safety hazards caused by excessive speed. At the same time, this gradient ratio is based on the engineering balance between the ship's mass and the track friction characteristics, achieving optimized compression of track length within a limited space. This reduces the amount of civil engineering work and land area, thereby improving the overall economy of the system while ensuring the smooth launch of the ship.

[0050] Optionally, multiple downhill inclined boat frames 5 are arranged alternately on the corresponding downhill tracks 3.

[0051] In this embodiment, in conjunction with the appendix Figure 1 As shown, staggered arrangement refers to the staggered arrangement of the lower-slope inclined ship frame 5 in the track system. It can be achieved by staggered arrangement. Its purpose is to disperse the weight distribution of the ship 100 and avoid stress concentration caused by parallel arrangement.

[0052] Optionally, the modular vehicle is equipped with a lifting mechanism, which is used to lift the vessel 100.

[0053] In this embodiment, the lifting mechanism can be a hydraulic jack system, which is installed on the frame of the modular vehicle 1. The piston rod is driven by a hydraulic pump to extend and retract to lift the ship 100, which is used to transfer the ship 100 from the modular vehicle 1 to the downhill inclined ship frame 5.

[0054] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0055] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
