Description
Technical Field
[0001] The utility model relates to the technical field of arrangement of ship docks and trolleys, and specifically to an arc-shaped ship dock and trolley connection structure which has a simple structure, is easy to use, extends the dock and the rolling distance of the trolley, and enables ships to be launched smoothly and safely. Background Art
[0002] As we all know, slipway resources are core resources in the shipbuilding industry. The size of slipway directly determines the size of ships built by a shipyard and the amount of ships completed. Slipway is a large-scale infrastructure with high cost. At present, the size and tonnage of conventional commercial ships are getting larger and larger, and shipyards are constantly transforming to high-tech ships. When encountering ships that exceed the original planning range, the slipway capacity cannot meet the order demand. The general solution is 1. No order can be accepted and the slipway is idle; 2. The slipway is reduced in weight after launching, and a floating crane is used or only the dock is closed twice, which greatly increases the shipbuilding cost and the ship is not easy to ship. During the launching process of a ship, the stern of the ship faces forward and the bow of the ship faces rearward. The stern of the ship enters the water first, and after entering the water, it will generate buoyancy on the stern of the ship. Then the ship will generate downward pressure on the bow of the ship. The bow of the ship generates a pressure of more than one thousand tons on the first trolley below it. Since the pressure of the trolley is too large, it will generate pressure on the dock. The bow of the ship will press the trolley tightly against the dock, so the ship cannot overcome the pressure between the bow of the ship, the trolley and the dock, resulting in the ship being unable to launch normally.

The gas output by the air pump 12 is input into the pressure airbag 10 through the high-pressure pipeline 11. The pressure airbag 10 of the first two cars 5 and the first three cars 6 expands upward to generate an upward pushing force on the lower part of the bow 3 of the ship 2, thereby reducing the pressure of the bow 3 of the ship 2 on the first car 4.
[0021] Furthermore, at least three trolleys under the tail 13 of the ship 2 are connected to each other, and at least three trolleys are connected to each other to form a conjoined tail trolley 14, and the left and right sides of each trolley in the conjoined tail trolley 14 are respectively connected to ear seats 25, and the ear seats 25 are connected to the wire rope 15. A rope clamp 16 is fixedly connected to the side panel of the tail 13 of the ship 2 corresponding to each trolley in the conjoined tail trolley 14, one end of the wire rope 15 is connected to the ear seat 25, and the other end of the wire rope 15 is connected to the rope clamp 16. The conjoined tail trolley 14 is connected to the tail 13 of the ship 2 through the wire rope 15, which increases the counterweight of the tail 13 of the ship 2. At the same time, the conjoined tail trolley 14 is lifted up by the tail 13 of the ship 2 and separated from the track 1, thereby extending the track 1 on which the ship 2 slides.
[0022] Further, the rope clamp 16 includes an I-shaped base 17, a clamping platform 18, a clamping rod 19, a buckling 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 ship 2, and the other horizontal plate of the I-shaped base 17 is fixedly connected to the clamping platform 18. The lower end of the clamping platform 18 is provided with a slot, and the clamping rod 19 is set to L-shaped. The vertical ends of the L-shaped clamping rod 19 are hinged to the clamping platforms 18 on both sides of the slot through the lower hinge shaft 22. The horizontal part of the L-shaped clamping rod 19 extends upward to the top of the clamping platform 18 and forms a rope clamping opening between the clamping platform 18. The buckling rod 20 is set to U-shaped, and the two ends of the opening of the U-shaped buckling rod 20 are respectively hinged to the upper end of the clamping platform 18 through the upper hinge shaft 21, and the closed end of the U-shaped buckling rod 20 is pressed on the outer wall of the lower end of the clamping rod 19 by rotation.
[0023] Furthermore, the pressure sensors 8 of the first car 4, the first second car 5 and the first third car 6 are respectively connected to the controller 23, and the controller 23 is respectively connected to the air pumps 12 on the first second car 5 and the first third car 6. The pressure data is transmitted to the controller 23 through the pressure sensor 8, and the controller 23 controls the working status of the air pumps 12 on the first second car 5 and the first third car 6.
[0024] 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, thereby increasing the strength of the I-shaped base 17 through the reinforcing rib plate 24 .
[0025] The clamping strip 29 on the inner wall of the clamping tube 27 is disengaged from the end face of the clamping boss 30, and the clamping strip 29 is disengaged from the end face of the clamping boss 30, thereby realizing the disassembly between the high-pressure pipeline and the air outlet pipe 26.
[0026] When the present invention is in use, the conjoined tail car 14 is connected to each other by 10 trolleys, and the 10 trolleys are connected to each other by hinges to form an integral structure. When in use again, the first car 4, the first second car 5 and the first third car 6 are respectively fixed on the track 1, and the air pump 12 is set as a high-power cylinder. The high-power air pump 12 and the controller 23 can be fixed on their respective trolleys, and can also be placed on the deck of the ship 2. The conjoined tail car 14 is fixed on the track 1, and the pressure-bearing air bag is pressed to the static stress state of the ship. The left and right sides of each trolley in the conjoined tail car 14 are respectively connected to the rope clamp 16 by a wire rope 15, and the end of the wire rope 15 connected to the rope clamp 16 is connected to a hook ring, the buckle rod 20 is lifted, and the hook ring is put on the L-shaped clamping rod The lateral part of 19 and the opening position of the clamping rope between the clamping platform 18 are adjusted, and then the fastening rod 20 is pressed down, and the closed end of the fastening rod 20 is pressed on the outer wall of the lower end of the clamping rod 19 by rotation. The arrangement of the trolley between the first three cars 6 and the connected tail car 14 adopts the existing technology, and the intervals thereof can be arranged on the track 1 of the ship 2. The trolley drives the ship 2 to move on the track 1 by pulling the trolley. In the process of the ship 2 moving along the track 1 on the curved trolley dock and launching, the pressure sensor 8 is turned on, and the pressure sensor 8 transmits the pressure received by the first car 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, and the pressure of the first car 4 gradually increases. At this time, according to The pressure values of the first car 4, the first two cars 5 and the first three cars 6 are continuously inflated to the pressure-bearing air bags 10 of the first cars 2 and 3 through the air pump 12, so as to share the pressure of the first car 1 until the ship 2 is completely floated. After complete floating, if the high-power air pump 12 and the controller 23 are placed on the deck of the ship 2, the high-pressure pipeline 11 is manually separated from the air pump by the ship 2 and the ship is dropped. If the high-power air pump 12 and the controller 23 are fixed on their respective trolleys, 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 ship 2 are directly connected to the rope clamp 16 fixed on the outer plate of the ship 2 through the wire rope 15. As the stern 13 of the ship 2 floats, the trolleys are also moved along with the stern of the ship 2. The bow 13 floats, plays a loading role, and reduces the space occupied by the underwater slideway, which in disguise makes the ship 2 slide down the track 1 farther, meeting the condition that the bow 3 is completely floating. After the entire ship 2 floats, it moves to the dock, and the buckle rod 20 on the rope clamp 16 is flipped to disengage the clamping rod 19, and the clamping rod 19 is flipped downward, thereby disengaging the wire rope 15, and then the connected tail car 14 of the tail 13 of the ship 2 is moved to the shore by a crane, and the rope clamp 16 on the side panel of the tail 13 of the ship 2 is cut off by a cutting machine. At this time, the launching of the curved slipway and dock is completed. Due to the above-mentioned structure, the utility model has the advantages of simple structure, easy use, extended dock and extended rolling distance of the slipway car, and smooth and safe launching of the ship 2.
