Description

Technical Field

[0001] This invention relates to the field of ship dock and trolley arrangement technology, specifically a simple, convenient, and efficient ship launching process using an arc-shaped dock, which extends the dock and the rolling distance of the trolley, ensuring the smooth and safe launching of the ship. Background Technology

[0002] As is well known, slipway resources are a core resource in the shipbuilding industry. The size of the slipway directly determines the size of a shipyard's vessels and its completion rate. Because slipways are large-scale infrastructure facilities with high costs, and with the increasing size and tonnage of conventional commercial ships and shipyards continuously transforming towards high-tech vessels, slipway capacity often cannot meet order demands when faced with vessels exceeding the original planning scope. Common solutions include: 1. No orders can be accepted, leaving the slipway idle; 2. The weight of the slipway assembly is reduced, requiring the use of floating cranes or secondary assembly in the dry dock after launching. This significantly increases shipbuilding costs. During the launching process, the stern of the ship faces forward and the bow faces backward. The stern enters the water first, which creates buoyancy. This creates downward pressure on the bow, which exerts a pressure of more than 1,000 tons on the first trolley below it. Due to the excessive pressure on the trolley, pressure is also exerted on the dock. The bow of the ship presses the trolley tightly against the dock, and the ship cannot overcome the pressure between the bow, the trolley, and the dock, thus preventing the ship from launching normally. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a simple, easy-to-operate method for launching ships using an arc-shaped dock, which extends the dock passage and the rolling distance of the trolley, and ensures the smooth and safe launching of ships.

[0004] The technical solution adopted by this invention to solve its technical problem is: A method for launching a ship using an arc-shaped slipway, characterized by the following steps: (1) Design of the trolley under the bow of the ship: an airbag is installed on the trolley under the bow of the ship to adjust the pressure between the bow of the ship and the trolley. (2) Design of the trolley under the stern of the ship: The trolley under the stern of the ship is connected to the stern of the ship. (3) Launching the ship: During the launching process, the stern of the ship generates buoyancy and fills the gas in the airbag, reducing the pressure of the bow of the ship on the trolley and the track of the arc-shaped dock. The stern of the ship is subjected to buoyancy and the trolley connected to the stern will disengage the trolley from the track of the arc-shaped dock until the ship is completely disengaged from the track of the arc-shaped dock.

[0005] The specific method for designing the ship trolley below the bow of the ship in step (1) of the present invention is as follows: the first, second and third ship trolleys below the bow of the ship are respectively the first bow trolley, the second bow trolley and the third bow trolley. The first bow trolley is provided with a pressure block above it. The pressure block is fixedly connected to the body of the first bow trolley via a pressure sensor. The second and third bow trolleys are provided with airbag brackets above them. The airbag brackets are fixed to the bodies of the second and third bow trolleys via pressure sensors. The airbag brackets are connected to pressure-bearing airbags inside. The pressure-bearing airbags are connected to an air pump via a high-pressure pipeline. The gas output by the air pump is input into the pressure-bearing airbags via a high-pressure pipeline. The pressure-bearing airbags of the second and third bow trolleys expand upward and exert an upward thrust on the bow of the ship, thereby reducing the pressure of the bow of the ship on the first bow trolley.

[0006] The specific method for designing the trolley below the stern of the ship in step (2) of the present invention is as follows: at least three trolleys below the stern of the ship are connected to each other, and the at least three trolleys are connected to each other to form a connected stern car. Each trolley in the connected stern car is connected to lugs on its left and right sides, and the lugs are connected to wire ropes. Each trolley in the connected stern car is fixedly connected to a rope clamp on the stern side plate of the ship. One end of the wire rope is connected to the lug, and the other end of the wire rope is connected to the rope clamp. The connected stern car is connected to the stern of the ship through the wire rope, which increases the counterweight of the stern of the ship. At the same time, the connected stern car is lifted off the track by the stern of the ship, thereby extending the track for the ship to slide.

[0007] The rope clamp of the present invention includes an I-shaped base, a clamping platform, a clamping rod, a fastening rod, an upper hinge shaft, and a lower hinge shaft. One horizontal plate of the I-shaped base is welded to the side plate at the stern of the ship. The clamping platform is fixedly connected to the other horizontal plate of the I-shaped base. The lower end of the clamping platform is provided with a clamping groove. The clamping rod is L-shaped. The vertical end of the L-shaped clamping rod is hinged to the clamping platform on both sides of the clamping groove via the lower hinge shaft. The horizontal part of the L-shaped clamping rod extends upward to the top of the clamping platform and forms a rope clamping opening with the clamping platform. The fastening rod is U-shaped. The two ends of the opening of the U-shaped fastening rod are respectively hinged to the upper end of the clamping platform via the upper hinge shaft. The closed end of the U-shaped fastening rod is pressed against the outer wall of the lower end of the clamping rod by rotation.

[0008] The pressure sensors of the first, second, and third vehicles described in this invention are respectively connected to the controller, and the controller is respectively connected to the air pumps on the first second and third vehicles. The pressure data is transmitted to the controller through the pressure sensors, and the controller controls the working status of the air pumps on the first second and third vehicles respectively.

[0009] The I-shaped base of the present invention has a reinforcing rib plate connected to the vertical plate. One side of the reinforcing rib plate is fixedly connected to the vertical plate, and the other side of the reinforcing rib plate is fixedly connected to the horizontal plate. The strength of the I-shaped base is increased by the reinforcing rib plate.

[0010] The air pump of the present invention has its outlet pipe connected to the end of a high-pressure pipeline via a clamping connector. The bottom of the clamping connector has a stepped hole, the small hole of which is connected to the high-pressure pipeline. An elastic annular sealing gasket is connected to the step at the connection between the large hole and the small hole of the stepped hole. The outer end of the inner wall of the large hole of the clamping connector has a clamping strip, and the outer wall of the air pump's outlet pipe has a clamping boss. The clamping strip of the clamping connector is inserted along the gap between the clamping bosses and rotated to clamp the clamping strip onto the end face of the clamping boss. When disassembly is required, the air pump is turned off, and the clamping connector is pushed toward the outlet pipe. Due to the elasticity of the annular sealing gasket, the clamping strip on the inner wall of the clamping connector is disengaged from the end face of the clamping boss. Then, the clamping connector is rotated, and the clamping strip comes out along the gap between the clamping bosses, thus achieving disassembly between the high-pressure pipeline and the outlet pipe.

[0011] The specific steps for launching the ship in step (3) of this invention are as follows: the first, second, and third trolleys are fixed on the track respectively, the air pump and controller are fixed on their respective trolleys or placed on the deck of the ship, the pressure-bearing airbags are pressurized to the static stress state of the ship, the stern car is fixed on the track, the left and right sides of each trolley in the stern car are connected to the rope clamps by steel wire ropes, the ends of the steel wire ropes connected to the rope clamps are connected to hooks, the buckling rod is lifted, and the hooks are put into the rope clamping opening position between the horizontal part of the L-shaped clamping rod and the clamping platform. Then the locking rod is pressed down, and the closed end of the locking rod is pressed against the outer wall of the lower end of the clamping rod by rotation. The ship is placed on the trolley placed on the track. The trolley pulls the ship to move on the track. During the process of the ship moving and launching along the track on the arc-shaped dockway with the trolley, the pressure sensor is activated. The pressure sensor transmits the pressure on the first trolley to the controller. After the stern of the ship enters the water, buoyancy is generated at the stern, and the buoyancy gradually increases as the launching process progresses. The pressure on the first trolley gradually increases. At this time, according to the pressure of the first, second, and third trolleys... The pressure value is continuously increased by air pumps to inflate the pressure-bearing airbags of the first two and third airbags, thus sharing the pressure of the first airbag until the ship is fully afloat. After full afloat, if the high-power air pump and controller are located on the ship's deck, the high-pressure pipeline is manually disconnected from the air pump and dropped off the ship. If the high-power air pump and controller are fixed to their respective trolleys, then there is no need to handle the connection between the high-pressure pipeline and the air pump. The trolley at the stern of the ship is directly connected to the rope clamps fixed to the ship's outer plating via steel wire ropes. As the ship... When the stern 13 is lifted, the trolley also rises with the stern of the ship, which serves to load the cargo and reduce the space occupied by the underwater slideway. This indirectly allows the ship to slide a longer distance on the track, meeting the condition that the bow is completely floating. After the entire ship floats, it is moved to the dock. The locking rod on the rope clamp is flipped off the locking rod, and the locking rod flips downward, thus releasing the wire rope. Then, the stern car is moved to the shore by a crane, and the rope clamps on the side plate of the stern are cut off by a cutting machine. At this point, the launching of the arc-shaped dock is completed.

[0012] The present invention, by employing the above-mentioned process method, has the advantages of being simple in method, convenient in operation, extending the dock passage and the rolling distance of the trolley, and ensuring the smooth and safe launching of ships. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings: As shown in the attached figure, a method for launching a ship using an arc-shaped slipway is characterized by the following steps: (1) Design of the trolley under the bow of the ship: an airbag is installed on the trolley under the bow of the ship to adjust the pressure between the bow of the ship and the trolley. (2) Design of the trolley under the stern of the ship: The trolley under the stern of the ship is connected to the stern of the ship. (3) Launching the ship: During the launching process, the stern of the ship generates buoyancy and fills the gas in the airbag, reducing the pressure of the bow of the ship on the trolley and the track of the arc-shaped dock. The stern of the ship is subjected to buoyancy and the trolley connected to the stern will disengage the trolley from the track of the arc-shaped dock until the ship is completely disengaged from the track of the arc-shaped dock.

[0021] Furthermore, the specific method for designing the trolley below the bow of the ship in step (1) is as follows: the first, second, and third trolleys below the bow of the ship 2 are respectively the first trolley 4, the second trolley 5, and the third trolley 6. The first trolley 4 is provided with a pressure block 7 above it. The pressure block 7 is fixedly connected to the body of the first trolley 4 via a pressure sensor 8. The second trolley 5 and the third trolley 6 are provided with an airbag bracket 9 above them. The airbag bracket 9 is fixed to the body of the second trolley 5 and the third trolley 6 via a pressure sensor 8. The airbag bracket 9 is connected to a pressure airbag 10 inside it. The pressure airbag 10 is connected to an air pump 12 via a high-pressure pipeline 11. The gas output by the air pump 12 is input into the pressure airbag 10 via the high-pressure pipeline 11. The pressure airbag 10 of the second trolley 5 and the third trolley 6 expands upward and exerts an upward thrust on the bow of the ship 2, thereby reducing the pressure of the bow of the ship 2 on the first trolley 4.

[0022] Furthermore, the specific method for designing the trolley below the stern of the ship in step (2) is as follows: at least three trolleys below the stern 13 of the ship 2 are connected to each other, forming a connected stern car 14. Each trolley in the connected stern car 14 has lugs 25 connected to its left and right sides, and lugs 25 are connected to wire ropes 15. Each trolley in the connected stern car 14 has a rope clamp 16 fixedly connected to the side plate of the stern 13 of the ship 2 corresponding to it. One end of the wire rope 15 is connected to the lug 25, and the other end of the wire rope 15 is connected to the rope clamp 16. The connected stern car 14 is connected to the stern 13 of the ship 2 through the wire rope 15, which increases the counterweight of the stern 13 of the ship 2. At the same time, the connected stern car 14 is lifted off the track 1 by the stern 13 of the ship 2, thereby extending the track 1 for the ship 2 to slide.

[0023] Furthermore, the rope clamp 16 includes an I-shaped base 17, a clamping platform 18, a clamping rod 19, a fastening rod 20, an upper hinge shaft 21, and a lower hinge shaft 22. One horizontal plate of the I-shaped base 17 is welded to the side plate of the stern 13 of the vessel 2, and the clamping platform 18 is fixedly connected to the other horizontal plate of the I-shaped base 17. The lower end of the clamping platform 18 is provided with a clamping groove. The clamping rod 19 is L-shaped. The vertical end of the L-shaped clamping rod 19 is hinged to the clamping platform 18 on both sides of the clamping groove via the lower hinge shaft 22. The horizontal part of the L-shaped clamping rod 19 extends upward to the clamping platform 18 and forms a rope clamping opening with the clamping platform 18. The fastening rod 20 is U-shaped. The two ends of the opening of the U-shaped fastening rod 20 are respectively hinged to the upper end of the clamping platform 18 via the upper hinge shaft 21. The closed end of the U-shaped fastening rod 20 is pressed against the outer wall of the lower end of the clamping rod 19 by rotation.

[0024] Furthermore, the pressure sensors 8 of the first vehicle 4, the second vehicle 5, and the third vehicle 6 are respectively connected to the controller 23. The controller 23 is respectively connected to the air pumps 12 on the second vehicle 5 and the third vehicle 6. The pressure data is transmitted to the controller 23 through the pressure sensors 8, and the controller 23 controls the working status of the air pumps 12 on the second vehicle 5 and the third vehicle 6 respectively.

[0025] Furthermore, a reinforcing rib plate 24 is connected to the vertical plate of the I-shaped base 17. One side of the reinforcing rib plate 24 is fixedly connected to the vertical plate, and the other side of the reinforcing rib plate 24 is fixedly connected to the horizontal plate. The strength of the I-shaped base 17 is increased by the reinforcing rib plate 24.

[0026] Furthermore, the air outlet pipe 26 of the air pump 12 is connected to the end of the high-pressure pipeline 11 via a clamping connector 27. The bottom of the clamping connector 27 is provided with a stepped hole, the small hole of which is connected to the high-pressure pipeline 11. An elastic annular sealing gasket 28 is connected to the step at the connection between the large hole and the small hole of the stepped hole. The outer end of the inner wall of the large hole of the clamping connector 27 is provided with a clamping strip 29. The outer wall of the air outlet pipe 26 of the air pump is provided with a clamping boss 30. After the clamping strip 29 of the clamping connector 27 is inserted along the gap between the clamping bosses 30, it is rotated and clamped onto the end face of the clamping bosses 30. When disassembly is required, the air pump 12 is turned off, and the clamping connector 27 is pushed toward the air outlet pipe 26. Due to the elasticity of the annular sealing gasket 28, the clamping strip 29 on the inner wall of the clamping connector 27 is disengaged from the end face of the clamping bosses 30. Then, the clamping connector 27 is rotated, and the clamping strip 29 is disengaged along the gap between the clamping bosses 30, thereby realizing the disassembly of the high-pressure pipeline and the air outlet pipe 26.

[0027] The specific steps for launching the ship in step (3) are as follows: the first trolley 4, the second trolley 5, and the third trolley 6 are fixed on the track 1 respectively. The air pump 12 and the controller 23 can be fixed on their respective trolleys or placed on the deck of the ship 2. The stern car 14 is fixed on the track 1. The pressure-bearing airbag is pressurized to the static stress state of the ship. The left and right sides of each trolley in the stern car 14 are connected to the rope clamps 16 by steel wire ropes 15. The ends of the steel wire ropes 15 connected to the rope clamps 16 are connected to hooks. The buckling rod 20 is lifted, and the hooks are put into the rope clamping opening between the horizontal part of the L-shaped clamping rod 19 and the clamping platform 18. Then the hooks are fastened. When rod 20 is pressed down, the closed end of the locking rod 20 is pressed against the lower end of the snap-fit ​​rod 19 by rotation. The ship is placed on the trolley placed on the track. The arrangement of the trolleys between the first three trolleys 6 and the connected stern trolley 14 adopts the existing technology arrangement, which can be arranged at intervals on the track 1 of the ship 2. The trolleys pull the ship 2 to move on the track 1. During the process of the ship 2 moving and launching along the track 1 on the arc-shaped dockway with the trolley, the pressure sensor 8 is opened. The pressure sensor 8 transmits the pressure received by the first trolley 4 to the controller 23. After the stern 13 of the ship 2 enters the water, the stern 13 of the ship 2 generates buoyancy, and the buoyancy gradually increases with the launching process. The first trolley 4 As the pressure gradually increases, based on the pressure values ​​of the first three vehicles (4, 5, and 6), the air pump 12 continuously inflates the pressure-bearing airbags 10 of the first three vehicles to share the pressure of the first vehicle until the vessel 2 is fully afloat. After full afloat, if the high-power air pump 12 and controller 23 are placed on the deck of the vessel 2, the high-pressure pipeline 11 is manually disconnected from the air pump and dropped off the vessel. If the high-power air pump 12 and controller 23 are fixed on their respective trolleys, then there is no need to process the connection between the high-pressure pipeline and the air pump. The 10 trolleys at the stern 13 of the vessel 2 are connected to the rope clamps fixed to the outer plate of the vessel 2 by steel wire ropes 15. The clamp 16 is directly connected. As the stern 13 of the vessel 2 rises, the trolley also rises with the stern 13 of the vessel 2, which plays a role in loading and reducing the space occupied by the underwater slideway. This indirectly allows the vessel 2 to slide a longer distance on the track 1, meeting the condition that the bow 3 is completely floating. After the entire vessel 2 floats, it moves to the dock. The locking rod 20 on the rope clamp 16 flips and disengages from the locking rod 19. The locking rod 19 flips downward, thereby detaching the wire rope 15. Then, the crane moves the connected stern car 14 of the stern 13 of the vessel 2 to the shore. The rope clamp 16 on the side plate of the stern 13 of the vessel 2 is cut off by a cutting machine. At this time, the launching of the arc-shaped dock is completed.

[0028] The aforementioned connected tail car 14 consists of 10 interconnected trolleys, which are connected to each other by hinges to form an integral structure. The aforementioned air pump 12 is a high-power cylinder. Due to the above structure, this invention has the advantages of simple method, convenient operation, extended dock passage and extended rolling distance of trolleys, and smooth and safe launching of ship 2.
