Description

Technical Field

[0001] This utility model relates to the field of marine technology, and in particular to a novel marine ramp. Background Technology

[0002] A ship gangway is a bridge between a ship and the ground. It is mainly used to facilitate the passage of people or the transportation of goods. In terms of cargo loading and unloading, compared with the use of cranes at the dock, its advantages are flexibility, convenience, fast scheduling and high efficiency.

[0003] However, existing gangplanks have the following problems. First, whether driven by hydraulic cylinders or steel cables, the rotation angle of the gangplank cannot exceed 180°. For ships with strict space requirements, this results in a space utilization defect. Second, the width of the gangplank is constant. For example, when passengers use gangplanks for boarding (which are mostly located at the ship's side and are narrow), it is impossible to carry cargo wider than the width of the gangplank. Such cargo can only be loaded into the cargo hold using gangplanks specifically for cargo loading (which are mostly located at the stern and are wider). However, gangplanks specifically for cargo loading have higher requirements for the dock. Or, in some cases, it is necessary to complete the boarding or disembarking of passengers quickly, but the width of the gangplank limits the speed of boarding or disembarking. Third, during the unloading process, when the cargo itself is heavy, the cargo accelerates as it slides down the gangplank, which can easily lead to the cargo sliding down too fast, resulting in poor safety.

[0004] In view of this, there is an urgent need for a new type of marine ramp to solve the above problems. Utility Model Content

One end of the plank body is fixedly connected to the plank connecting end. The two sets of side plates are connected to both sides of the plank body by bearings. The plank extension assembly is fixedly connected to the plank body and movably connected to the two sets of side plates.

[0009] Preferably, the sliding cavity includes a through transverse cavity and multiple longitudinal cavities, with the lower ends of the multiple longitudinal cavities penetrating the transverse cavity and their upper ends penetrating the top wall of the scaffold body.

[0010] Preferably, the anti-slip component includes multiple fan-shaped blocking blocks and a sliding plate. The sliding plate is provided with multiple fan-shaped notches that match the fan-shaped blocking blocks. The sliding plate is slidably connected in the transverse cavity, and the multiple fan-shaped blocking blocks are respectively hinged to the upper ends of the side walls of multiple longitudinal cavities.

[0011] Preferably, the sliding plate has two sets of locking holes on the end away from the fixed plate, and the locking holes are equipped with matching locking pins, with the lower end of the locking pin passing through the body of the sliding plate and located inside the locking hole.

[0012] Preferably, the ramp extension assembly includes two sets of support plates, a drive motor, a first helical gear, a first rotating shaft, a second helical gear, a second rotating shaft, a main drive wheel, a frame support assembly, and multiple auxiliary tilting components. The two sets of support plates are respectively fixedly connected to the bottom wall of the ramp body. The drive motor is fixedly connected to one of the support plates. One end of the first rotating shaft is connected to the drive motor, and the other end passes through the first helical gear and multiple auxiliary tilting components in sequence before being connected to the bearing of the other support plate. The multiple auxiliary tilting components are respectively staggeredly connected to the two sets of side plates. One end of the second rotating shaft is connected to the bearing of the bottom wall of the ramp body, and the other end passes through the main drive wheel before being connected to the second helical gear by a key. The second rotating shaft is also keyed to the main drive wheel. The frame support assembly is movably connected to the bottom wall of the ramp body and is driven by the main drive wheel. The first helical gear and the second helical gear are meshed together.

[0013] Preferably, the skeleton support assembly includes a transmission belt, auxiliary transmission wheels, multiple sets of turntables, multiple sets of skeletons, and multiple sets of third rotating shafts. One end of each set of third rotating shafts is fixedly connected to the platform body, and the other end passes through the auxiliary transmission wheels and is fixedly connected to the turntables.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The connecting plate and the fixed plate are connected by bearings to achieve the purpose of rotating the ramp through the connecting plate. The rotation angle of the connecting plate is large in this rotation method, which has the advantage of effectively utilizing the space of the ship.

[0019] 2. With the anti-slip components in place, multiple fan-shaped blocking blocks can be rotated by the movement of the sliding plate when needed. This rotation causes the curved parts of the fan-shaped blocking blocks to protrude outside the body of the ramp, thereby reducing the sliding speed of the goods.

[0020] 3. The plank extension component, through the cooperation of the skeleton support component and the auxiliary flipping component, allows the side plate, which originally served as a guardrail, to be flipped, thus extending the width of the plank body. At the same time, considering the problem of insufficient bottom support of the flipped side plate, the skeleton support component is used to further reinforce it. Attached Figure Description

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Example 1

[0030] Please see the appendix Figure 1-5 A new type of marine gangway, comprising:

[0031] The system comprises two sets of fixed plates 1, two sets of connecting plates 2, a springboard 3, and an anti-slip component 4. One end of each fixed plate 1 has a connecting notch 10, and the other end is fixedly connected to a fixed body. Each connecting notch 10 has a matching rotating shaft 100. One end of each connecting plate 2 is located within the connecting notch 10, and the other end is fixedly connected to the springboard 3. One end of the rotating shaft 100 passes through the fixed plate 1 and is fixedly connected to the connecting plate 2 located within the connecting notch 10, while the other end is connected to a drive component. The rotating shaft 100 is also connected to a bearing in the fixed plate 1. The springboard 3 has a sliding cavity 30, and the anti-slip component 4 is movably connected within the sliding cavity 30.

[0032] Based on existing technology, by using the connection plate 2 and the fixed plate 1 in combination, the ramp 3 can rotate around the pivot 100 with the connection plate 2. At the same time, the use of the connection plate 2 creates a certain gap between the ramp 3 and the hull, which indirectly expands the rotation range of the ramp 3. The anti-slip component 4 installed on the ramp 3 can continuously decelerate the cargo during the unloading process, preventing the cargo from accelerating as it slides down, thus avoiding the situation where the cargo slides down too fast and causes personal injury or cargo damage.

[0033] It is worth noting that this utility model does not limit the drive component of the rotating shaft 100. Theoretically, a drive component, such as a motor, can be connected to a single rotating shaft 100 to drive the gangway 3 to rotate. However, considering that in practical applications, if a motor is used directly for drive, part of the gravity borne by the gangway 3 during loading and unloading of cargo or passenger boarding will be fed back to the drive component, which may shorten the actual service life of the drive component, this utility model suggests using a reducer, a hydraulic motor, and a hydraulic pump station to jointly constitute the drive of the rotating shaft 100. The rotating shaft 100 is mounted on the reducer, the hydraulic motor is connected to the reducer, and finally the hydraulic pump station is connected to the hydraulic motor to provide power. When the gangway needs to be flipped, the hydraulic pump station is started, the hydraulic motor drives the reducer, and the torque is amplified by the reducer to drive the gangway to rotate. This method uses mechanical transmission, has a simple and stable structure, and is less affected by the reverse force on the gangway.

[0034] Specifically, the ramp 3 includes a ramp connecting end 31, a ramp body 32, two sets of side plates 33, and a ramp extension assembly 5. The ramp connecting end 31 is located near the fixed plate 1. One end of the ramp body 32 is fixedly connected to the ramp connecting end 31. The two sets of side plates 33 are bearing connected to both sides of the ramp body 32. The ramp extension assembly 5 is fixedly connected to the ramp body 32 and movably connected to the two sets of side plates 33. By disassembling the traditional single-structure ramp 3 into a ramp connecting end 31, a ramp body 32, and side plates 33, the two sets of side plates 33 can normally act as guardrails to protect passengers. When loading goods with a larger width, the side plates 33 can be rotated by adjusting the ramp extension assembly 5 and become flat with the ramp body 32, directly expanding the passage for loading goods.

[0035] Specifically, the sliding cavity 30 includes a through transverse cavity 300 and a plurality of longitudinal cavities 301. The lower ends of the plurality of longitudinal cavities 301 penetrate the transverse cavity 300, and their upper ends penetrate the top wall of the springboard body 3.

[0036] Specifically, the anti-slip component 4 includes a plurality of fan-shaped blocking blocks 40 and a sliding plate 41. The sliding plate 41 is provided with a plurality of fan-shaped notches 410 that match the fan-shaped blocking blocks 40. The sliding plate 41 is slidably connected to the transverse cavity 300. The plurality of fan-shaped blocking blocks 40 are respectively hinged to the upper end of the side wall of the plurality of longitudinal cavities 301.

[0037] Specifically, the sliding plate 41 is provided with two sets of locking holes 411 at the end away from the fixed plate 1, and the locking hole 411 is provided with a matching locking pin 4110. The lower end of the locking pin 4110 passes through the jump plate body 32 and is located in the locking hole 411.

[0038] Considering that ramp 3 may be tilted during actual unloading, the goods may accelerate due to gravity. Without other deceleration measures, the goods may have excessive speed at the end of ramp 3, making them prone to tipping over upon contact with the ground. This could result in damage to the goods themselves or, in severe cases, injury to personnel receiving the goods at the end of ramp 3. Therefore, an anti-slip component 4 is installed. Under normal conditions, the fan-shaped barrier block 40 is located inside the sliding cavity 30, almost overlapping with the fan-shaped notch 410 on the sliding plate 41. When anti-slip is required on ramp 3, the locking pin 4110 is first removed, and then the sliding plate 41 is displaced by external force. As the sliding plate 41 displaces, the sidewall of the fan-shaped notch 410 moves. During the movement, an external force is applied to the fan-shaped barrier block 40, causing it to rotate until it is completely separated from the fan-shaped notch 410. At this time, the arc surface of the fan-shaped barrier block 40 is outside the sliding cavity 30. Finally, the locking pin 4110 is inserted into the locking hole 411 to fix the position of the sliding plate 41. When the goods slide down, they need to pass through the arc surfaces of multiple fan-shaped barrier blocks 40 in sequence, which means they need to decelerate multiple times to reduce the speed of the goods sliding down. When the anti-slip component 4 is no longer needed, the sliding plate 41 can be moved back to its original position. During this process, the fan-shaped barrier block 40 will gradually fall into the fan-shaped notch 410 under the action of gravity, and the surface of the springboard body 32 will return to its initial flatness.

[0039] It should be noted that the source of the pulling force applied to the sliding plate 41 is mainly determined by the specifications of the anti-slip component 4. When the width of the fan-shaped blocking block 40 and the corresponding sliding plate 41 is small, the overall weight is small, and the external force required for the sliding plate 41 to move and drive the fan-shaped blocking block 40 is also small. When there is no pressure when pulling by hand, a corresponding pulling handle can be set at one end of the sliding plate 41 to provide the power for the displacement of the sliding plate 41. Correspondingly, in this case, since the width of the fan-shaped blocking block 40 is small, the resistance it can provide is also small. Conversely, when the width of the fan-shaped blocking block 40 and the sliding plate 41 is large, the overall weight is also large, and it is difficult to provide the power for the displacement of the sliding plate 41 by hand. In this case, a matching cylinder can be installed inside the transverse cavity 300 to drive the displacement of the sliding plate 41. In this case, the function of the locking pin 4110 and the locking hole 411 can also be replaced by the cylinder.

[0040] Specifically, the springboard extension assembly 5 includes two sets of support plates 50, a drive motor 51, a first helical gear 52, a first rotating shaft 53, a second helical gear 54, a second rotating shaft 55, a main drive wheel 56, a frame support assembly 57, and multiple auxiliary tilting assemblies 58. The two sets of support plates 50 are respectively fixedly connected to the bottom wall of the springboard body 32. The drive motor 51 is fixedly connected to one of the support plates 50. One end of the first rotating shaft 53 is connected to the drive motor 51, and the other end passes through the first helical gear 52 and multiple auxiliary tilting assemblies in sequence. The component 58 is then connected to another support plate 50 by a bearing, and the multiple auxiliary flipping components 58 are respectively connected to the two sets of side plates 33 in an alternating manner. One end of the second rotating shaft 55 is connected to the bottom wall of the springboard body 32 by a bearing, and the other end passes through the main drive wheel 56 and is keyed to the second helical gear 54. The second rotating shaft 55 is keyed to the main drive wheel 56. The frame support component 57 is movably connected to the bottom wall of the springboard body 32 and is connected to the main drive wheel 56 in a transmission connection. The first helical gear 52 and the second helical gear 54 are meshed together.

[0041] Specifically, the frame support assembly 57 includes a transmission belt 570, auxiliary transmission wheels 571, multiple sets of turntables 572, multiple sets of frames 573, and multiple sets of third rotating shafts 574. One end of each set of third rotating shafts 574 is sequentially fixedly connected to the platform body 32, and the other end passes through the auxiliary transmission wheels 571 and is fixedly connected to the turntables 572. The third rotating shafts 574 are keyed to the auxiliary transmission wheels 571. Adjacent sets of auxiliary transmission wheels 571 are connected by transmission belts 570. The auxiliary transmission wheel 571 near the second helical gear 54 is connected to the main transmission wheel 56 by transmission belts 570. At least one set of frames 573 is fixedly connected to the side wall of the turntable 572, and adjacent sets of frames 573 do not contact each other.

[0042] Specifically, the frame 573 is greater than 1 / 2 the width of the springboard body 32;

[0043] In practical applications, when there is a need to increase the actual width of the gangplank 3, such as when loading larger cargo or when it is necessary to speed up the boarding and disembarking of passengers, the actual width of the gangplank 3 can be extended through the gangplank extension component 5. The specific operation is as follows:

[0044] The drive motor 51 is started, which drives the first rotating shaft 53 to rotate. The first rotating shaft 53 drives the first helical gear 52 and multiple auxiliary tilting components 58 to rotate. Through the joint action of multiple auxiliary tilting components 58, the side plates 33 located on both sides of the main body 32 of the gangway rotate until the side plates 33 and the main body 32 of the gangway are on the same plane, thereby expanding the actual application width of the gangway 3. At the same time, considering that after the side plates 33 rotate, during the loading of cargo or passenger boarding, the pressure on the side plates 33 will be directly fed back to the bearing connection between the side plates 33 and the main body 32 of the gangway and the auxiliary tilting components 58. Since the bottom of the side plates 33 has no support, this defect may reduce its service life at best, and at worst, it may cause the side plates to lose their support function and cause accidents because the side plates cannot bear the weight of the cargo or passengers on them.

[0045] To avoid the aforementioned problems, while the drive motor 51 drives the first helical gear 52 and multiple auxiliary tilting components 58 via the first rotating shaft 53, the meshing connection between the first helical gear 52 and the second helical gear 54 drives the rotation of the second helical gear 54 and the second rotating shaft 55. The second rotating shaft 55 then drives the rotation of the main drive wheel 52. Finally, the adjacent auxiliary drive wheels 571 are connected by a transmission belt 570, so that the auxiliary drive wheels 571 rotate synchronously as the main drive wheel 52 rotates. This, in turn, drives the auxiliary drive wheels 571 and the third rotating shaft 574.

[0046] The rotation of turntable 573 causes the frame 573, which was originally located at the bottom of the springboard body 32, to change position. Since the length of the frame 573 is greater than 1 / 2 of the width of the springboard body 32, part of the frame 573 after changing position will inevitably be located at the bottom of the side plate 33, forming the frame 573 of the side plate 33, and sharing some of the pressure on the side plate 33.

[0047] Specifically, the auxiliary flipping assembly 58 includes gears 580, chain 581, and two sets of connecting ropes 582. The gears 580 are sequentially keyed to the first rotating shaft 53. The chain 581 is meshed with the gears 580. The two sets of connecting ropes 582 are respectively fixedly connected to both ends of the chain 581, and the ends of the two sets of connecting ropes 582 away from the chain 581 are fixedly connected to the side plate 33.

[0048] Specifically, the end of the connecting rope 582 away from the chain 581 is fixedly connected to the side wall opposite to the side plate 33, and the side plate 33 is provided with a groove 330 that matches the connecting rope 582.

[0049] To further improve the utilization rate of space in the ship, this utility model uses a gear 580, a chain 581, and two sets of connecting ropes 582 to form an auxiliary tilting assembly 58. The advantage of this method is that the auxiliary tilting assembly 58 is located on the gangway 3 and does not occupy additional space inside the ship during daily use. The specific usage is as follows:

[0050] When the first rotating shaft 53 rotates under the drive of the drive motor 51, it also drives multiple gears 580 to rotate. The rotation of the gears 580 causes the chain 581 meshing with them to shift. One end of each of the two sets of connecting ropes 582 is fixedly connected to the two sides opposite to the side plate, and the other end is connected to both ends of the chain 581. For ease of description, the connecting rope 582 in contact with the pressure surface of the side wall is called rope one, and the other connecting rope 582 is called rope two. When the side wall 33 is perpendicular to the main body 32 of the ramp, the distance between the chain 581 at both ends of the gear 580 and the side plate is... Similarly, when it is necessary to expand the actual application width of the jumping board 3, the gear 580 rotates. At this time, the chain 581 moves towards the direction of rope one under the rotation of the gear 580. At this time, rope two is pulled by the chain 581, which in turn pulls the side plate to rotate away from the jumping board body 32. This is the unfolding process of the side plate 33. When it is necessary to retract the side plate 33, the rotation of the gear 580 can drive the chain 582 to move towards the direction of rope two. At this time, rope one will be pulled by the chain 582, which in turn drives the side plate 33 to rotate towards the direction of the jumping board body 32.

[0051] Meanwhile, considering that the rope 1 on the surface of the side plate 33 may obstruct the loading of goods, a hidden groove 330 is opened on the side plate 33 to hide the connecting rope 582 inside, so as to avoid affecting the normal loading of goods.

[0052] Example 2

[0053] Please refer to the attached Figure 6

[0054] Considering that when adjusting the rotation angle of the ramp 3, when driven by a drive motor or hydraulic cylinder, the locking of the ramp 3 after rotation can only rely on the drive motor and hydraulic cylinder themselves, in order to reduce the load on the drive motor and hydraulic cylinder, and at the same time to more accurately control the maximum adjustable angle of the ramp 3, an angle adjustment assembly is set up, which includes an angle adjustment hydraulic cylinder 60, a connecting block 61 and an angle adjustment plate 62. The angle adjustment hydraulic cylinder 60 is fixedly connected to the support plate 50 near the ramp connection end 31. The angle adjustment plate 62 is slidably connected to the ramp connection end 31 near the support plate 50. The connecting block 61 is fixedly connected to the angle adjustment plate 62 and the piston rod of the angle adjustment hydraulic cylinder 60 respectively.

[0055] When the maximum rotation angle of the gangway 3 needs to be adjusted, the angle adjustment hydraulic cylinder 60 is activated. The extension or retraction of its piston rod drives the displacement of the angle adjustment plate 62. When the gangway 3 rotates with the connecting plate 2, the angle adjustment plate 62 located on the outside of the gangway connection end 31 will rotate and contact the outer wall or hull of the ship first, further hindering the rotation of the gangway 3. The longer the angle adjustment plate 62 located on the outside of the gangway connection end 31, the smaller the maximum rotation angle of the gangway 3. At the same time, when the gangway body 32 is subjected to the pressure of cargo or passengers, part of the pressure will be distributed to the angle adjustment plate 62. Through the contact between the angle adjustment plate 62 and the ship's side wall or hull, the pressure distributed on the angle adjustment plate 62 will be transferred to the ship itself, thereby achieving the purpose of sharing the load of the drive motor or hydraulic cylinder and indirectly increasing the service life of the drive motor or hydraulic cylinder.

[0056] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
