Description

Technical Field

[0001] This invention relates to the field of emergency boarding bridge technology, specifically a marine emergency boarding bridge. Background Technology

[0002] After a large vessel is launched, its main deck is approximately 20 meters higher than the dockside. Furthermore, tidal forces cause the difference in elevation between the vessel's deck and the dockside to exceed 4 meters. Therefore, a boarding bridge is necessary for boarding operations. However, existing boarding bridges are generally fixed, making adjustment and assembly inconvenient. They cannot be used as temporary emergency structures according to actual needs. Moreover, existing boarding bridges cannot effectively adjust their height according to the rising and falling tides, nor can their length be adjusted to accommodate vessel movement, causing inconvenience for emergency boarding or disembarking.

[0003] A utility model patent with application number 201921400526.3 discloses a floating dock for offshore bridge construction, allowing construction personnel to travel between the shore and the offshore construction site by boat. It includes a boarding platform set in the water and a staircase connecting the boarding platform to the shore. The boarding platform is a box-like structure floating on the water and connected to anchor piles fixed to the shore by cables. The staircase includes a fixed section and a movable section. The fixed section is fixedly supported on the shore ground, and one end of the movable section is rotatably connected to the fixed section via a pivot, while the other end is supported on the boarding platform. This utility model allows the boarding platform to rise and fall with the water level along with the vessel without any difference in elevation, thus facilitating boarding.

[0004] Although the aforementioned floating dock uses rotatable and adjustable steps, the height and length of the steps can only be adjusted by rotating the fixed and movable sections. The adjustment range is limited, and the steps may move laterally during the movement, affecting the stability of the steps and compromising the safety of personnel using the steps in emergencies. Summary of the Invention

[0005] The purpose of this invention is to provide a marine emergency boarding bridge to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a marine emergency boarding bridge, comprising a frame, the frame comprising a first box and a second box, the upper end of the first box being provided with a ship-receiving inclined ladder, the upper end of the second box being provided with a grounding inclined ladder, a guiding walking mechanism being provided between the upper end of the first box and the ship-receiving inclined ladder, a connecting mechanism for assembly being provided on one side of the lower end of both the grounding inclined ladder and the ship-receiving inclined ladder, the lower end connecting mechanism of the grounding inclined ladder being used to connect to the second box, the lower end connecting mechanism of the ship-receiving inclined ladder being used to connect to the hull, a top plate being provided at the upper end of the first box and the second box, and a bottom plate being provided at the lower end of the first box and the second box.

[0007] Preferably, the guiding walking mechanism includes a fixed frame, a mounting block, walking wheels, and a sliding groove; a fixed frame is fixedly installed at the lower end of the ship-receiving inclined ladder, and a mounting block is fixedly installed on one side of the fixed frame at the lower end of the ship-receiving inclined ladder. The walking wheels are movably installed inside the mounting block via a rotating shaft. There are two walking wheels, which are symmetrically distributed on both sides of the lower end of the ship-receiving inclined ladder. A sliding groove is fixedly installed on the surface of the top plate at the upper end of the first box body. There are two sliding grooves, which are symmetrically distributed at the upper end of the top plate. The walking wheels are movably engaged inside the sliding grooves.

[0008] Preferably, the connecting mechanism includes a connecting block, a first buckle, a second buckle, and an elastic connecting rope. The lower ends of the grounding inclined ladder and the ship-receiving inclined ladder are both fixedly provided with connecting blocks. The lower end of the connecting block is fixedly provided with a first buckle. A second buckle is movably provided on one side of the surface of the first buckle through a rotating shaft. An elastic connecting rope is fixedly provided inside the connecting block. The lower end of the elastic connecting rope is fixedly connected to the second buckle.

[0009] Preferably, a hanging rod for cooperating with the connecting mechanism is fixedly installed on the upper end of the first box near the grounding inclined ladder.

[0010] Preferably, a tie rod is provided between the bottom plate and the top plate.

[0011] Preferably, protective railings are provided at the upper ends of the top plate, the ship-receiving inclined ladder, and the grounding inclined ladder; the protective railings are symmetrically distributed on both sides of the upper ends of the top plate, the ship-receiving inclined ladder, and the grounding inclined ladder.

[0012] Preferably, both ends of the grounding inclined ladder and the ship-receiving inclined ladder are movably equipped with connecting plates via rotating shafts.

[0013] Preferably, the outer surface of the connecting plate is provided with anti-slip grooves.

[0014] Preferably, an extended inclined ladder is provided on one side of the second box.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. Under the action of the guiding walking mechanism, this invention allows the connected vessel to move back and forth to a certain extent when it sways, thereby driving the receiving ladder to move back and forth a certain distance within the chute. However, the guiding walking mechanism only allows the receiving ladder to move back and forth, and under the limiting effect of the chute, it cannot move laterally, thus ensuring the safety of the device during use. Furthermore, through the connection principle of this device, the receiving ladder is allowed to rotate relative to the rotating shaft to a certain extent. And the first and second latches are engaged on the outer surface of the hanging rod, which will not prevent the rotation of the receiving ladder. This further improves the flexibility of the device during use.

[0017] 2. The present invention can prevent the first and second buckles from separating from the hanging rod when there is vibration or swaying of the ship, thus ensuring the overall connection stability and safety of the device. When it is necessary to disassemble and separate the first buckle from the hanging rod, simply use a crane to slowly lift the grounding ladder and the ship-connecting ladder, giving the second buckle sufficient time to open. Thus, the device is not only easy to install, but also has excellent safety.

[0018] 3. The first and second containers are easy to assemble during the assembly of this invention. The bottom plate and top plate are installed on the outer surfaces of the first and second containers by means of tie rods. Then, the first and second containers can be quickly disassembled from the bottom plate and top plate as needed. It is also convenient to reassemble them later. The first and second containers of this device are traditional containers. They can be easily found at the dock. Thus, they can be easily assembled at any time by means of tie rods.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-7 This invention provides a technical solution: a marine emergency boarding bridge, comprising a frame, the frame including a first box 1 and a second box 2, the upper end of the first box 1 being provided with a ship-reaching inclined ladder 3, the upper end of the second box 2 being provided with a grounding inclined ladder 4, a guiding walking mechanism being provided between the upper end of the first box 1 and the ship-reaching inclined ladder 3, and a connecting mechanism for assembly being provided on one side of the lower end of the grounding inclined ladder 4 and the ship-reaching inclined ladder 3, the lower end connecting mechanism of the grounding inclined ladder 4 being used to connect to the second box 2, the lower end connecting mechanism of the ship-reaching inclined ladder 3 being used to connect to the hull, the upper end of the first box 1 and the second box 2 being provided with a top plate 5, and the lower end of the first box 1 and the second box 2 being provided with a bottom plate 6.

[0029] The guiding and walking mechanism includes a fixed frame 7, a mounting block 8, walking wheels 9, and a slide 10. The lower end of the ship-receiving inclined ladder 3 is fixedly provided with the fixed frame 7, and the lower end of the ship-receiving inclined ladder 3 is fixedly provided with the mounting block 8 on one side of the fixed frame 7. Two walking wheels 9 are movably mounted inside the mounting block 8 via a rotating shaft, symmetrically distributed on both sides of the lower end of the ship-receiving inclined ladder 3. Two slide 10s are fixedly provided on the surface of the top plate 5 at the upper end of the first housing 1, symmetrically distributed on the upper end of the top plate 5. The walking wheels 9 are movably engaged inside the slide 10. When using the device, the ship-receiving inclined ladder 3 only needs to connect to a ship, and the guiding and walking mechanism allows the ship to move forward and backward to a certain extent when the connected ship sways, thereby driving the ship-receiving inclined ladder 3 to move forward and backward a certain distance within the slide 10. However, the guiding and walking mechanism only allows the ship-receiving inclined ladder 3 to move forward and backward, and under the limiting effect of the slide 10, it cannot move laterally, thus ensuring the safety of the device during use.

[0030] The connecting mechanism includes a connecting block 11, a first buckle 12, a second buckle 13, and an elastic connecting rope 14. Both the grounding inclined ladder 4 and the ship-receiving inclined ladder 3 have a connecting block 11 fixedly installed at their lower ends. A first buckle 12 is fixedly installed at the lower end of the connecting block 11. A second buckle 13 is movably installed on one side of the surface of the first buckle 12 via a rotating shaft. An elastic connecting rope 14 is fixedly installed inside the connecting block 11, and the lower end of the elastic connecting rope 14 is fixedly connected to the second buckle 13. This connecting mechanism facilitates the connection of the grounding inclined ladder 4 to the second housing 2 and the connection of the ship-receiving inclined ladder 3 to the ship hull.

[0031] A hanging rod 15 for cooperating with the connecting mechanism is fixedly installed on the upper end of the first housing 1 near the grounding inclined ladder 4. The hanging rod 15 can be conveniently fixed to the connecting mechanism on the surface of the grounding inclined ladder 4. Since the hull to which this device is connected is not shown in each view, a corresponding hanging rod 15 should also be installed on the surface of the hull to which this device is connected in order to cooperate with the use of this device. Since the connection principle and limiting principle between the connecting mechanism on the surface of the grounding inclined ladder 4 and the hanging rod 15 are the same as the connection principle and limiting principle between the ship-connecting inclined ladder 3 and the hanging rod 15 on the surface of the hull, this application only describes the connection principle and limiting principle between the grounding inclined ladder 4 and the hanging rod 15. The connection principle is as follows: When it is necessary to connect the grounding inclined ladder 4 and the first housing 1, the grounding inclined ladder 4 is lifted. At this time, the second buckle 13 in the connecting mechanism is in a rotating and open state under its own weight. The specific state can be as follows. Figure 6 As shown, at this time, the distance between the second buckle 13 and the first buckle 12 is relatively large, and it can be easily locked onto the outer surface of the hanging rod 15 in the lifting state, thereby completing the connection between the first box 1 and the grounding inclined ladder 4.

[0032] The limiting principle is as follows: After the first housing 1 is connected to the grounding inclined ladder 4, and the ship-connecting inclined ladder 3 is connected to the ship hull, the weight of the grounding inclined ladder 4 will press against the upper outer surface of the second buckle 13, causing the second buckle 13 to rotate around the pivot, thereby forming... Figure 5 as well as Figure 7 In the state shown, the gap between the first buckle 12 and the second buckle 13 becomes very small, and the hanging rod 15 cannot be disengaged from the first buckle 12 and the second buckle 13. During the connection, the hull sways, causing the entire device to vibrate and sway. When the grounding inclined ladder 4 moves upward relative to the hanging rod 15, the second buckle 13, no longer compressed, will gradually return to its original position under its own gravity. Figure 6 As shown in the diagram, under the action of the elastic connecting rope 14, the second buckle 13 needs to overcome the elastic force of the elastic connecting rope 14 when it rotates to open, so it can only open slowly. However, since the vibrations are instantaneous, the second buckle 13 has not yet rotated to the threshold angle under the action of gravity. The grounding inclined ladder 4 resets during the vibration, and the second buckle 13 contacts the hanging rod 15 again. Thus, the vibration and the swaying of the ship cannot separate the first buckle 12, the second buckle 13 and the hanging rod 15, thereby ensuring the overall connection stability and safety of the device. When it is necessary to disassemble and separate the first buckle 12 and the hanging rod 15, it is only necessary to use a crane to slowly lift the grounding inclined ladder 4 and the ship-connecting inclined ladder 3, giving the second buckle 13 sufficient time to open.

[0033] A tie rod 16 is provided between the bottom plate 6 and the top plate 5. The bottom plate 6 and the top plate 5 are installed on the outer surfaces of the first container 1 and the second container 2 by the tie rod 16. Then, the first container 1 and the second container 2 can be quickly disassembled from the bottom plate 6 and the top plate 5 as needed. Reassembly is also convenient. The first container 1 and the second container 2 of this device are traditional containers. They can be easily found at the dock. Thus, the tie rod 16 makes it easy to assemble at any time.

[0034] The top plate 5, the ship-receiving inclined ladder 3, and the grounding inclined ladder 4 are all equipped with protective railings 17; the protective railings 17 are symmetrically distributed on both sides of the top plate 5, the ship-receiving inclined ladder 3, and the grounding inclined ladder 4; the protective railings 17 can ensure the basic safety of the device during use.

[0035] Both ends of the grounding inclined ladder 4 and the ship-receiving inclined ladder 3 are movably equipped with connecting plates 18 via rotating shafts. The connecting plates 18 can fill the joints at both ends of the grounding inclined ladder 4 and the ship-receiving inclined ladder 3, making it convenient for users to walk.

[0036] The outer surface of the connecting plate 18 is provided with an anti-slip groove 19, which can prevent the user from slipping on the upper part of the connecting plate 18.

[0037] An extension inclined ladder 20 is provided on one side of the second box 2, which can be conveniently connected to the reception platform or the ground.

[0038] It should be noted that the present invention does not show the docking vessel. Before use, in order to cooperate with the use of this device, the surface of the docking vessel should also be equipped with the corresponding hanging rod 15.

[0039] Working principle: When using this invention, the device needs to be assembled first. The first container 1 and the second container 2 are easy to assemble. The bottom plate 6 and the top plate 5 are installed on the outer surfaces of the first container 1 and the second container 2 by means of the tie rods 16. Then, the first container 1 and the second container 2 can be quickly disassembled from the bottom plate 6 and the top plate 5 as needed. Reassembly is also relatively convenient. The first container 1 and the second container 2 of this device are both traditional containers. They can be easily found at the dock. Thus, the tie rods 16 make it easy to assemble at any time.

[0040] Next, the ship-receiving inclined ladder 3 and the grounding inclined ladder 4 are installed. During installation, the grounding inclined ladder 4 and the ship-receiving inclined ladder 3 are lifted. At this time, the second buckle 13 in the connecting mechanism is in a rotating and open state under its own weight. The specific state can be described as follows: Figure 6As shown, at this time, the distance between the second buckle 13 and the first buckle 12 is relatively large, and it can be easily locked onto the outer surface of the hanging rod 15 in the lifting state, thereby completing the connection between the first box 1 and the grounding inclined ladder 4, and the ship receiving inclined ladder 3 and the ship; (and the connection method between the second box 2 and the ship receiving inclined ladder 3 can also utilize this principle).

[0041] After the connection is completed, under the action of the guiding walking mechanism, the connected vessel can move back and forth to a certain extent when it sways, thereby driving the receiving ladder 3 to move back and forth a distance within the slide 10. However, the guiding walking mechanism only allows the receiving ladder 3 to move back and forth, and under the limiting action of the slide 10, it cannot move laterally, thus ensuring the safety of the device during use. Furthermore, through the connection principle of this device, the receiving ladder 3 is allowed to rotate relative to the rotating shaft to a certain extent. And the first buckle 12 and the second buckle 13 are engaged on the outer surface of the hanging rod 15, which will not prevent the rotation of the receiving ladder 3. This further improves the flexibility of the device during use.

[0042] After assembly, the connection mechanism of this device also has a limit function;

[0043] After the first housing 1 is connected to the grounding inclined ladder 4, and the ship-connecting inclined ladder 3 is connected to the hull, the grounding inclined ladder 4, under its own weight, will press against the upper outer surface of the second buckle 13, causing the second buckle 13 to rotate around the pivot, thus forming... Figure 5 as well as Figure 7 In the state shown, the gap between the first buckle 12 and the second buckle 13 becomes very small, and the hanging rod 15 cannot be disengaged from the first buckle 12 and the second buckle 13. During the connection, the hull sways, causing the entire device to vibrate and sway. When the grounding inclined ladder 4 moves upward relative to the hanging rod 15, the second buckle 13, no longer compressed, will gradually return to its original position under its own gravity. Figure 6 As shown in the diagram, under the action of the elastic connecting rope 14, the elastic force of the elastic connecting rope 14 always drives the second buckle 13 to rotate and close, that is, the elastic force of the elastic connecting rope 14 always aims to keep the second buckle 13 in a closed position. Figure 5 as well as Figure 7As shown, the elastic force is limited and cannot overcome the weight of the second buckle 13, only playing a damping role. Therefore, when the second buckle 13 rotates to open, it needs to overcome the elastic force of the elastic connecting rope 14, thus it can only open slowly. However, since the vibrations are instantaneous, the second buckle 13 has not yet rotated to the threshold angle under the action of gravity (this threshold angle refers to the angle between the first buckle 12 and the second buckle 13 that allows the hanging rod 15 to disengage). The grounding inclined ladder 4 resets during the vibration, and the second buckle 13 and the hanging rod 15 reconnect. The second buckle 13 is far from the hanging rod 15 during shaking and vibration, providing sufficient space to prevent it from contacting the hanging rod 15. This prevents the first buckle 12, second buckle 13 from separating from the hanging rod 15 during vibration and hull movement, thus ensuring the overall stability and safety of the device. When it is necessary to disassemble and separate the first buckle 12 from the hanging rod 15, simply use a crane to slowly lift the grounding ladder 4 and the ship-receiving ladder 3, giving the second buckle 13 sufficient time to open, to complete the disassembly.
