[0002] A ship is a general term for various vessels. Ship berthing and landing refers to a ship docking at a dock for activities such as loading and unloading goods and embarking and disembarking passengers. This process is commonly known as "landing". To facilitate passengers embarking and disembarking, a ship berthing and landing device is generally provided on the ship; In the existing ship berthing and landing devices, when a ship berths and lands, in order to avoid the situation where the heights of the ship and the riverbank are inconsistent and it is not convenient for people to go ashore, generally after the ship lands, one end of the landing board on the ship is connected to the ship, and the other end of the landing board is lapped on the shore to facilitate passengers embarking and disembarking. Although this kind of ship berthing and landing device can realize passengers embarking and disembarking, there are still the following deficiencies: One end of the landing board is directly lapped on the riverbank.

Detailed implementation manners

[0034] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0035] The present invention provides the following preferred embodiments: Embodiment 1: As Figures 1 - 13 shown, a ship berthing and landing device includes a shore plate 11, and further includes a lap joint block 12, a first positioning mechanism, a protection mechanism, and two second positioning mechanisms; The lap joint block 12 is integrally formed at one end of the shore plate 11, and a cavity 13 is formed inside the lap joint block 12; It should be noted that two connectors 56 are fixed at one end of the landing board 11 far away from the overlapping block 12. The connectors 56 are used to connect the landing board 11 to the ship. In actual use, the ship should be provided with a driving device for driving the landing board 11 to rotate, so that when the ship needs to berth, the driving device can drive the landing board 11 to turn from the ship to the river bank, so that the overlapping block 12 can overlap on the river bank, facilitating passengers to get on and off the ship; The first positioning mechanism includes a lifting assembly, two positioning cylinders 24 and two second jacks 51. The two positioning cylinders 24 are symmetrically arranged inside the cavity 13. The two second jacks 51 are both opened at the bottom end of the overlapping block 12. Each second jack 51 communicates with the cavity 13. The size of the second jack 51 matches the size of the positioning cylinder 24, so that the positioning cylinder 24 can pass through the second jack 51. Each positioning cylinder 24 is located above a second jack 51. The lifting assembly is installed between the overlapping block 12 and the two positioning cylinders 24; After the overlapping block 12 overlaps on the river bank, the lifting assembly can drive the positioning cylinder 24 to move downward. The positioning cylinder 24 passes through the second jack 51 and inserts into the soil to achieve lateral limit, and can position the landing board 11, so that the landing board 11 can stably overlap on the bank, improving the firmness and stability between the landing board 11 and the river bank, enabling passengers to get on and off the ship smoothly, and improving the safety factor; Two second positioning mechanisms are respectively installed inside the two positioning cylinders 24. Each second positioning mechanism includes a driving assembly, a telescopic assembly, a plurality of positioning rods 47 and a plurality of first jacks 50. The plurality of first jacks 50 are all opened on the surface of the positioning cylinder 24. Each positioning rod 47 is located on one side of a first jack 50. The shape and size of the first jack 50 match the positioning rod 47. The positioning rod 47 can move out of the positioning cylinder 24 through the second jack 51. The driving assembly and the telescopic assembly are both located inside the positioning cylinder 24; After the positioning cylinder 24 is inserted into the soil, the driving assembly can drive the telescopic assembly to work. The telescopic assembly can drive a plurality of positioning rods 47 to move, so that the positioning rods 47 can extend out of the positioning cylinder 24 and insert into the soil to achieve longitudinal limit, and can reposition the landing board 11, further improving the firmness and stability between the landing board 11 and the river bank; The protection mechanism includes two guardrails 15, two transmission assemblies and two rotating assemblies. The two guardrails 15 are symmetrically arranged at the top end of the landing board 11. One rotating shaft 14 is fixed at each end of the two guardrails 15 away from each other. Each rotating shaft 14 is rotatably arranged on the landing board 11. Each rotating assembly is installed on one side of a rotating shaft 14. Each transmission assembly is located between the lifting assembly and one of the rotating assemblies; When the positioning cylinder 24 moves downward under the action of the lifting assembly, the transmission assembly can drive the rotating assembly to work, so that the guardrail 15 can rotate above the shore board 11 and rotate from the horizontal state to the vertical state, which can play a protective effect on passengers when they board and alight from the ship. Through the arranged transmission assembly, when the positioning cylinder 24 moves downward, the two guardrails 15 can rotate, and the synchronization between the two is high. There is no need to manually lift the guardrail 15, which saves time and effort and can avoid the situation that the staff forgets to lift the guardrail 15, thus effectively avoiding the risk of pedestrians falling from the shore board 11.

[0036] As Figures 1 - 13 shown, the lifting assembly includes a lifting plate 22, two first guide rods 23, two lead screws 21 and a synchronizing member. The two first guide rods 23 are symmetrically fixed inside the cavity 13. The lifting plate 22 is slidably arranged on the two first guide rods 23. The first guide rods 23 play a guiding role for the lifting plate 22. The two lead screws 21 are respectively arranged on the sides of the two first guide rods 23 away from each other. Each lead screw 21 is rotatably arranged inside the cavity 13. The lifting plate 22 is arranged on the two lead screws 21. The lifting plate 22 is in threaded cooperation with the lead screws 21. The two positioning cylinders 24 are both fixed to the bottom end of the lifting plate 22. The synchronizing member is located at the top ends of the two lead screws 21. After the latching block 12 latches onto the riverbank, the synchronizing member can drive the two lead screws 21 to rotate. Since the lead screws 21 and the lifting plate 22 are in threaded connection and the lifting plate 22 and the first guide rods 23 are in sliding connection, when the lead screws 21 rotate, the lifting plate 22 can be driven to move along the length direction of the first guide rods 23, that is, the lifting plate 22 can drive the two positioning cylinders 24 to move downward, so that the two positioning cylinders 24 are inserted into the soil of the riverbank to realize the lateral limit and positioning of the shore board 11.

[0037] As Figures 1 - 13 shown, the synchronizing member includes a first motor 17, a chain 19 and two sprockets 18. A protective cover 20 is fixed to the top end of the latching block 12. The two sprockets 18 are both located inside the protective cover 20. The protective cover 20 is used to protect the sprockets 18 and the chain 19 to prevent inconvenience to passengers when boarding and alighting. The top end of each lead screw 21 passes through the latching block 12 and is fixed to a sprocket 18. The chain 19 is sleeved on the two sprockets 18. The first motor 17 is installed on the top end of the protective cover 20. The output end of the first motor 17 passes through the protective cover 20 and is connected to one of the sprockets 18. By controlling the first motor 17 to work through the controller, the first motor 17 can drive the sprocket 18 connected to it to rotate. Under the action of the chain 19, the two sprockets 18 can rotate synchronously, so that the two lead screws 21 can rotate synchronously.

[0038] As Figures 1 - 13As shown in the figure, the telescopic assembly includes a rotating rod 42, two mounting plates 41, two turntables 43, three moving frames 46, and a plurality of second guide rods 45. The two mounting plates 41 are both fixed to the inner wall of the positioning cylinder 24. The rotating rod 42 is rotatably arranged on the two mounting plates 41. The two turntables 43 are symmetrically fixed to both ends of the rotating rod 42. The three moving frames 46 are arranged annularly and equidistantly inside the positioning cylinder 24. A number of positioning rods 47 are respectively installed on one side of the three moving frames 46. Every two second guide rods 45 are inserted into one moving frame 46. The second guide rods 45 are slidably connected to the moving frames 46. One end of each second guide rod 45 is fixedly connected to the inner wall of the positioning cylinder 24. Two hinge rods 44 are hinged to one end of each moving frame 46 away from the positioning rod 47. The other ends of the two hinge rods 44 are respectively hinged to the two turntables 43. After the positioning cylinder 24 is inserted into the soil, the driving assembly can drive the rotating rod 42 to rotate. The rotating rod 42 can drive the turntable 43 to rotate. Under the action of the hinge rod 44, the moving frame 46 can be driven to move along the length direction of the second guide rod 45, so that the hinge rod 44 can drive the positioning rod 47 to move. The positioning rod 47 extends out of the positioning cylinder 24, so that the positioning rod 47 can also be inserted into the soil to realize longitudinal limitation, and the landing plate 11 can be repositioned, further improving the firmness and stability between the landing plate 11 and the river bank.

[0039] As Figures 1 - 13 As shown in the figure, the driving assembly includes a driving gear 52, a driven gear 53, a motor base 54, and a second motor 55. The motor base 54 is fixed to one side of the positioning cylinder 24. The driven gear 53 is fixedly installed on the surface of the rotating rod 42. The driving gear 52 is rotatably arranged at the bottom end of the motor base 54. The second motor 55 is installed at the top end of the motor base 54. The output end of the second motor 55 is fixedly connected to the driving gear 52. The driving gear 52 and the driven gear 53 are meshed with each other. By controlling the operation of the second motor 55, the second motor 55 can drive the driving gear 52 to rotate. Since the driving gear 52 and the driven gear 53 are meshed with each other, when the driving gear 52 rotates, it can drive the rotating rod 42 to rotate through the driven gear 53.

[0040] As Figures 1 - 13As shown in the figure, each transmission component includes a vertical plate 25, a side plate 30, a pulling rope 26, a rack 29, a reset member, and a plurality of guide wheels 27. The vertical plate 25 is fixedly installed inside the cavity 13. The side plate 30 is fixedly installed on one side of the lifting plate 22. When the lifting plate 22 lifts, it can drive the side plate 30 to lift synchronously. One side of the vertical plate 25 is fixed with a guide rail 28. The rack 29 is slidably arranged inside the guide rail 28. The guide rail 28 is used to guide the rack 29. A plurality of guide wheels 27 are rotatably arranged on one side of the vertical plate 25. One end of the pulling rope 26 is connected to the side plate 30. The other end of the pulling rope 26 bypasses a plurality of guide wheels 27 and is connected to one end of the rack 29. The guide wheels 27 are used to guide the pulling rope 26. The reset member is located on one side of the rack 29; It should be noted here that the pulling rope 26 is a steel rope.

[0041] As Figures 1 - 13 shown, the reset member includes a chute 31, a slider 32, a spring 33, and a fixing plate 34. The chute 31 is opened on the surface of the vertical plate 25. The chute 31 penetrates the vertical plate 25. The slider 32 is slidably arranged inside the chute 31. One end of the slider 32 is fixedly connected to the rack 29. The fixing plate 34 is located on one side of the chute 31 and is fixed on the surface of the vertical plate 25. The fixing plate 34 is located on the side of the vertical plate 25 away from the rack 29. The two ends of the spring 33 are respectively connected to the slider 32 and the fixing plate 34; In the initial state, the spring 33 is in a stretched state. When the side plate 30 moves downward with the lifting plate 22, under the action of the spring 33, it can drive the rack 29 to move in the guide rail 28 in a direction away from the pulling rope 26; When the positioning cylinder 24 is removed from the soil, the lifting plate 22 drives the side plate 30 to move upward. Under the action of the pulling rope 26, it can drive the rack 29 to move reversely in the guide rail 28, and the spring 33 is stretched.

[0042] As Figures 1 - 13 shown, each rotating component includes a first gear 35, a second gear 36, a driving wheel 37, a driven wheel 38, and a transmission belt 39. The driven wheel 38 is fixed at one end of the rotating shaft 14. The driving wheel 37 is rotatably arranged on one side of the vertical plate 25. The transmission belt 39 is sleeved on the driving wheel 37 and the driven wheel 38. The second gear 36 is fixed on one side of the driving wheel 37. The first gear 35 is rotatably arranged on the vertical plate 25. The rack 29, the first gear 35, and the second gear 36 are sequentially meshed and connected. An avoidance groove 40 for the transmission belt 39 to pass through is opened at the top of the overlapping block 12; When the rack 29 moves away from the pull rope 26 inside the guide rail 28, the rack 29 can drive the second gear 36 to rotate through the first gear 35. The second gear 36 drives the driving wheel 37 to rotate. Under the action of the transmission belt 39, the driven wheel 38 can be driven to rotate. The driven wheel 38 can drive the guardrail 15 to rotate from the horizontal state to the vertical state through the rotating shaft 14, which can play a protective role for passengers when they board and disembark from the ship, and further improve the safety factor. When the rack 29 moves in the reverse direction, through the first gear 35, the second gear 36, the driving wheel 37, the driven wheel 38, the transmission belt 39, etc., the rotating shaft 14 can be driven to rotate in the reverse direction, so that the guardrail 15 can rotate from the vertical state to the horizontal state, realizing the storage of the guardrail 15, reducing the occupied space, and facilitating the subsequent recycling of the shore landing plate 11 onto the ship.

[0043] As Figures 1 - 13 shown, two fixing seats 16 are fixed on both sides of the top end of the shore landing plate 11. Each rotating shaft 14 is rotatably arranged on the two fixing seats 16 through bearings. The fixing seats 16 are used to support the rotating shaft 14.

[0044] As Figures 1 - 13 shown, a plurality of second soil-breaking knives 49 are fixed on the surface of each positioning cylinder 24, and a plurality of first soil-breaking knives 48 are fixed on the surface of each positioning rod 47. By arranging the second soil-breaking knives 49 and the first soil-breaking knives 48, when the positioning cylinder 24 and the positioning rod 47 are inserted into the soil, they can cut the soil, facilitating the positioning cylinder 24 and the positioning rod 47 to penetrate into the soil and reducing the resistance.

[0045] The specific working process of the present invention is as follows: When the ship needs to berth, the driving device on the ship drives the shore landing plate 11 to flip from the ship to the river bank, so that the overlapping block 12 can overlap on the river bank. After the overlapping block 12 overlaps on the river bank, the controller controls the first motor 17 to work. The first motor 17 can drive the sprocket 18 connected thereto to rotate. Under the action of the chain 19, the two sprockets 18 can rotate synchronously, so that the two lead screws 21 can rotate synchronously. Since the lead screw 21 and the lifting plate 22 are in threaded connection, and the lifting plate 22 is slidably connected to the first guide rod 23, when the lead screw 21 rotates, it can drive the lifting plate 22 to move along the length direction of the first guide rod 23, that is, the lifting plate 22 can drive the two positioning cylinders 24 to move downward, so that the two positioning cylinders 24 are inserted into the soil of the river bank, realizing the lateral limit and positioning of the shore landing plate 11. After the positioning cylinder 24 is inserted into the interior of the soil, the second motor 55 is controlled to operate. The second motor 55 can drive the driving gear 52 to rotate. Since the driving gear 52 and the driven gear 53 mesh with each other, when the driving gear 52 rotates, it can drive the rotating rod 42 to rotate through the driven gear 53. The rotating rod 42 can drive the turntable 43 to rotate. Under the action of the hinge rod 44, it can drive the moving frame 46 to move along the length direction of the second guide rod 45, so that the hinge rod 44 can drive the positioning rod 47 to move. The positioning rod 47 extends out of the positioning cylinder 24, so that the positioning rod 47 can also be inserted into the interior of the soil, realizing longitudinal limitation, and can re-position the landing board 11, further improving the firmness and stability between the landing board 11 and the river bank. At the same time, the positioning cylinder 24 and the positioning rod 47 can respectively limit the landing board 11 in the horizontal and vertical directions, improving the anchoring effect of the landing board 11; When the lifting plate 22 moves downward, the lifting plate 22 drives the side plate 30 to move. Under the action of the spring 33, it can drive the rack 29 to move away from the pulling rope 26 inside the guide rail 28. The rack 29 can drive the second gear 36 to rotate through the first gear 35. The second gear 36 drives the driving wheel 37 to rotate. Under the action of the transmission belt 39, it can drive the driven wheel 38 to rotate. The driven wheel 38 can drive the guardrail 15 to rotate from the horizontal state to the vertical state through the rotating shaft 14, which can play a protective role for passengers when they get on and off the ship, further improving the safety factor; When the positioning cylinder 24 is removed from the interior of the soil, the lifting plate 22 drives the side plate 30 to move upward. Under the action of the pulling rope 26, it can drive the rack 29 to move reversely inside the guide rail 28, and the spring 33 is stretched.
