Description

Technical Field

[0001] This invention relates to the field of ship gangway technology, and more specifically, to a combined gangway for large ships. Background Technology

[0002] Ship gangways are facilities that facilitate the boarding and disembarking of personnel. Due to the height of large ships, they are equipped with gangways to adapt to different berthing environments and operational needs. To meet the needs of maritime rescue, ship replenishment, law enforcement inspections, crew changes, and offshore engineering operations, where personnel need to change ships, ship gangways ensure the safe and efficient conduct of these maritime activities.

[0003] In existing technologies, to flexibly adjust the angle and direction of the gangway to adapt to different berthing environments, changes in ship position, and the needs of maritime operations, while also facilitating the deployment and storage of the gangway and ensuring safety during navigation and efficiency during operations, the gangway on large ships is typically located on one side of the hull. A rotation drive and a crane are installed on the ship. One end of the gangway is fixed to the drive end of the rotation drive, and the traction end of the crane is fixed to the end of the gangway furthest from the rotation drive. In use, the rotation drive and crane are activated, and the gangway rotates along the output end of the rotation drive on the ship, thus adjusting the gangway's tilt angle. By using a rotation drive and crane in conjunction to drive the gangway's rotation, the gangway angle can be precisely controlled, flexibly adapting to different berthing and operational needs.

[0004] However, the aforementioned existing technologies still have shortcomings. When there are waves on the sea surface, if the waves generate axial force on the output end of the rotating drive, it will cause uneven force on the connection between the drive and the gangway, increase mechanical stress, cause component deformation or damage, reduce the accuracy and life of the drive, and affect the stability and safety of the gangway angle adjustment, increasing the risk of ship operation. Summary of the Invention

[0005] The present invention provides a combined gangway for large ships, which aims to solve the following problem: In existing combined gangways for large ships, the drive end of the rotating actuator is fixedly installed with the gangway. When there are waves on the sea surface, if the waves generate axial force on the output end of the rotating actuator, it will cause uneven stress on the connection between the actuator and the gangway, increase mechanical stress, cause component deformation or damage, reduce the accuracy and life of the actuator, and affect the stability and safety of the gangway angle adjustment, thus increasing the risk of ship operation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a combined gangway for large ships, comprising a combined gangway component, a rotation drive one and an auxiliary traction mechanism, the combined gangway component comprising a pedal one and a pedal two, the pedal two being slidably disposed within the pedal one, the output end of the rotation drive one being connected to the pedal one, and the rotation of the output end of the rotation drive one being used to drive the pedal one to perform circular motion along the center of the output end of the rotation drive one. The auxiliary traction mechanism includes a traction rope, on which a traction hook is provided. The traction hook is fixedly connected to the pedal. The traction rope is used to pull the end of the pedal away from the rotary driver to rotate. An adaptive adjustment mechanism is provided between pedal one and rotary driver one. The adaptive adjustment mechanism includes a connecting ball head, which is fixedly mounted on the output end of rotary driver one. A fixed seat is fixedly mounted on pedal one, and the connecting ball head is ball-hinged to the fixed seat.

[0007] Initially, pedal one is horizontally positioned on the ship. When the gangway needs to be lowered for personnel use, rotating actuators one and two are activated. The output of rotating actuator two unwinds the traction rope one, while the output of rotating actuator one drives pedal one to rotate in a circle around the center of the output of rotating actuator one. This, combined with the unwinding of the traction rope one, tilts pedal one, thus adjusting its posture. Once pedal one is adjusted to the desired posture, the output of rotating actuator one and the winding roller stop rotating, ensuring pedal one maintains the corresponding posture. By setting a connecting ball joint and a fixed seat, when the driving end of rotating actuator one rotates, the connecting shaft is engaged in a sliding groove. The connecting shaft, in conjunction with the sliding groove, drives the fixed seat to rotate synchronously, allowing rotating actuator one and traction rope one to adjust the tilt posture of pedal one in sync. If pedal one is tilted and the waves are large, causing radial pressure between pedal one and the drive end of rotary driver one, the sliding groove and connecting shaft can cause an angular deflection between pedal one and the drive end of rotary driver one. This prevents damage caused by radial force between pedal one and the drive end of rotary driver one due to the fixed setting, thus allowing pedal one and the drive end of rotary driver one to not be in a perpendicular state.

[0008] In a preferred embodiment, a sliding groove is provided on the fixed base, and a connecting shaft is fixedly provided on the connecting ball head, with the connecting shaft slidably disposed in the sliding groove.

[0009] In a preferred embodiment, the combined gangway component is further provided with an anti-collision mechanism, which includes a second towing hook, which is fixedly mounted on the combined gangway component. A second towing rope is fixedly mounted on the second towing hook, which is inclinedly mounted on the combined gangway component. A towing machine is fixedly mounted at the top of the second towing rope.

[0010] In a preferred embodiment, the anti-collision mechanism further includes a second linear driver, which is fixedly mounted on the first pedal. A support is fixedly mounted on the output end of the second linear driver, and a roller is rotatably mounted on the support.

[0011] In a preferred embodiment, a groove is provided on the support base, and an adjusting seat one and an adjusting seat two are slidably disposed in the groove. An elastic element is provided between the adjusting seat one and the adjusting seat two. A fixed shaft is fixedly disposed on the roller, and the fixed shaft is slidably disposed in the groove.

[0012] In a preferred embodiment, the fixed shaft is in contact with the first adjusting seat, and a pressure sensor is fixedly installed on the support seat, with the sensor's acquisition end in contact with the second adjusting seat.

[0013] In a preferred embodiment, a linear actuator is fixedly mounted on pedal one, and the output end of linear actuator one is fixedly mounted on pedal two. Guardrails are fixedly mounted on both pedal one and pedal two.

[0014] In a preferred embodiment, the auxiliary traction mechanism further includes a fixed frame, on which a support arm is fixedly mounted, and on which a winding roller is rotatably mounted, and the top end of the traction rope is fixed and wound around the winding roller.

[0015] In a preferred embodiment, an extension arm is slidably mounted on the support arm, and a guide wheel is rotatably mounted on the extension arm, with the guide wheel and the traction rope rotating together.

[0016] In a preferred embodiment, a second rotary driver is fixedly mounted on the fixed frame. The output end of the second rotary driver is fixedly mounted to the support arm, and the rotation of the output end of the second rotary driver is used to drive the support arm to rotate.

[0017] When traction rope one and traction rope two lift pedal one to reset, linear actuator two is activated. The moving drive roller at the output end of linear actuator two contacts the hull of the ship. When the roller contacts the hull, it provides a reaction force to adjusting seat one. The reaction force pushes adjusting seat two towards the pressure sensor's acquisition end through the elastic element. The pressure sensor's acquisition end obtains the pressure parameter. More precisely, when the pressure sensor's acquisition end obtains a pressure of 300N from the roller feedback, there is no need to adjust the moving position of the linear actuator two's output end. If the pressure sensor receives a pressure less than this value from the roller feedback, the output end of linear actuator two then drives the support seat to move towards the hull of the ship, ensuring that the rollers on the multiple output ends of linear actuator two can all fit against the hull of the ship, making the pedal one's posture reset more stable and further improving the safety of the staff on pedal one.

[0018] Furthermore, through the cooperation of the linear actuator and the roller, not only can support be provided between the pedal and the ship's hull, ensuring that the pedal maintains a stable posture during the rotation and reset process, but also, since the tilt angle of the ship's side is not the same, through the cooperation of the pressure sensor and elastic components, the distance between the roller and the ship's hull can be adaptively adjusted according to the changes in the tilt angle of the ship's hull at different heights, ensuring that the distance between the pedal and the ship's hull is always the same, thereby further improving the stability of the pedal's posture reset process.

[0019] The beneficial effects of this invention are as follows: 1. By setting a connecting ball head and a fixed seat, this invention not only enables the pedal to rotate through the rotation of the drive end of the rotary driver, but also provides redundancy between the pedal and the drive end of the rotary driver when encountering waves. Even if wind and waves generate axial force through the pedal to the output end of the rotary driver, the force on the connection between the output end of the rotary driver and the pedal can be ensured to be uniform, avoiding mechanical stress that could cause component deformation or damage. This ensures the accuracy and lifespan of the drive, improves the stability and safety of gangway angle adjustment, and eliminates risks in ship operations.

[0020] 2. By setting up an anti-collision mechanism, the present invention, through the cooperation of the linear actuator and the roller, not only provides support between the pedal and the ship's hull, ensuring that the pedal maintains a stable posture during the rotation and reset process, but also, because the tilt angle of the ship's hull is not the same, through the cooperation of pressure sensors and elastic components, can adaptively adjust the distance between the roller and the ship's hull according to the changes in the tilt angle of the ship's hull at different heights, ensuring that the distance between the pedal and the ship's hull is always the same, thereby further improving the stability of the pedal's posture reset process.

[0029] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0030] Refer to the instruction manual appendix Figures 1 to 5 A combined gangway for large ships includes a combined gangway component 1, a rotation drive 2, and an auxiliary traction mechanism 3. The combined gangway component 1 includes a pedal 11 and a pedal 2 12. The pedal 2 12 is slidably disposed in the pedal 11. The output end of the rotation drive 2 is connected to the pedal 11. The rotation of the output end of the rotation drive 2 is used to drive the pedal 11 to make a circular motion around the center of the output end of the rotation drive 2. The auxiliary traction mechanism 3 includes a traction rope 34, on which a traction hook 35 is provided. The traction hook 35 is fixedly disposed with the pedal 11. The traction rope 34 is used to pull the end of the pedal 11 away from the rotary driver 2 to rotate. An adaptive adjustment mechanism 4 is provided between the pedal 11 and the rotary driver 2. The adaptive adjustment mechanism 4 includes a connecting ball head 41, which is fixedly mounted on the output end of the rotary driver 2. A fixed seat 42 is fixedly mounted on the pedal 11, and the connecting ball head 41 is ball-hinged onto the fixed seat 42. A sliding groove 421 is provided on the fixed seat 42, and a connecting shaft 43 is fixedly mounted on the connecting ball head 41. The connecting shaft 43 is slidably mounted within the sliding groove 421.

[0031] A linear actuator 13 is fixedly installed on the combined gangway component 1. The output end of the linear actuator 13 is fixedly installed on the second step 12. Guardrails 14 are fixedly installed on both the first step 11 and the second step 12.

[0032] The auxiliary traction mechanism 3 also includes a fixed frame 31, on which a support arm 32 is fixedly mounted. A winding roller 33 is rotatably mounted on the support arm 32, and the top end of the traction rope 34 is fixed and wound around the winding roller 33. An extension arm 321 is slidably mounted on the support arm 32, and a guide wheel is rotatably mounted on the extension arm 321. The guide wheel and the traction rope 34 are rolled together. A second rotation driver is fixedly mounted on the fixed frame 31. The output end of the second rotation driver is fixedly mounted to the support arm 32, and the rotation of the output end of the second rotation driver drives the support arm 32 to rotate.

[0033] It should be noted that the rotary drive 2 includes, but is not limited to, a hydraulic motor. Hydraulic motors can generate significant torque and their rotation speed can be precisely controlled, thus achieving stable adjustment of the gangway's rotation speed. The hydraulic system is relatively closed, making it adaptable to harsh marine environments such as salt spray and humidity, and its failure rate is relatively low. Furthermore, the circulating lubrication of hydraulic oil can reduce wear on the motor's internal components. Hydraulic motors are a mature existing technology and will not be discussed in detail here.

[0034] It should also be noted that the linear actuator 13 includes, but is not limited to, a hydraulic cylinder or an electric push rod. After the linear actuator 13 is activated, it enables the pedal 2 12 to extend and retract within the pedal 11, thereby adjusting the overall length of the combined gangway component 1. The combination of pedal 11 and pedal 2 12 is easy to adjust for use by personnel according to their needs. The rotary actuator 2 is a motor, which is fixedly mounted on the support arm 32. The output shaft of the motor is fixedly mounted to the winding roller 33.

[0035] Furthermore, the extension arm 321 is slidably disposed within the support arm 32 and is fixed to the support arm 32 by bolts. The overall length of the support arm 32 and the extension arm 321 can be adjusted according to usage requirements, facilitating the traction rope 34 to pull the lifting pedal 11. The rotary drive 2 and the fixing frame 31 are both fixedly installed on the ship's deck.

[0036] It is worth mentioning that the descriptions of the output terminal of rotary driver 2, the drive terminal of rotary driver 2, and the output shaft of rotary driver 2 in the following text all refer to the same thing.

[0037] The specific implementation scenario is as follows: In the initial state, pedal 11 is horizontally set on the ship. When the gangway needs to be lowered for personnel use, rotary actuators 2 and 3 are activated. The output of rotary actuator 2 rotates and unwinds the traction rope 34. The output of rotary actuator 2 drives pedal 11 to rotate around the center of the output of rotary actuator 2. In conjunction with the unwinding of the traction rope 34, pedal 11 is tilted, thus adjusting its posture. Once pedal 11 is adjusted to the desired posture, the output of rotary actuator 2 and the winding roller 33 stop rotating, ensuring that pedal 11 maintains the corresponding posture. By setting a connecting ball head 41 and a fixed seat 42, when the driving end of rotary actuator 2 rotates, the connecting shaft 43 is engaged in the sliding groove 421. The connecting shaft 43, in conjunction with the sliding groove 421, can drive the fixed seat 42 to rotate synchronously, allowing rotary actuator 2 and traction rope 34 to synchronously adjust the tilt posture of pedal 11. If pedal 11 is tilted and the waves are large, causing radial pressure between pedal 11 and the drive end of rotary driver 2, the sliding groove 421 and the connecting shaft 43 can cause an angular deflection between pedal 11 and the drive end of rotary driver 2. This prevents damage caused by radial force between pedal 11 and the drive end of rotary driver 2 due to their fixed installation. In other words, it allows pedal 11 and the drive end of rotary driver 2 to be in a non-perpendicular state.

[0038] Compared with the existing technology, by setting the connecting ball head 41 and the fixed seat 42, not only can the pedal 11 be rotated by the rotation of the drive end of the rotary driver 2, but also when encountering waves, there is redundancy between the pedal 11 and the drive end of the rotary driver 2. The pedal 11 and the drive end of the rotary driver 2 do not need to be in a perpendicular state at all times. Even if the wind and waves generate axial force on the output end of the rotary driver 2 through the pedal 11, it can be ensured that the output end of the rotary driver 2 and the connection part of the pedal 11 are subjected to uniform force, avoiding mechanical stress that could cause component deformation or damage. This ensures the accuracy and life of the drive, improves the stability and safety of the gangway angle adjustment, and eliminates the risks of ship operation.

[0039] Refer to the instruction manual appendix Figure 6When a worker stands on the inclined step 11, during the process of rotating step 11 to reset, there may still be waves. Even if the connection ball 41 and the fixed seat 42 can avoid damage to the components due to radial force, the presence of waves may cause step 11 to sway radially along the output end of the rotary driver 2 during the reset process. The swaying of step 11 will pose a safety hazard to the worker. To avoid the above situation, specifically, the combined gangway component 1 is also equipped with an anti-collision mechanism 5. The anti-collision mechanism 5 includes a second traction hook 52, which is fixedly installed on the combined gangway component 1. A second traction rope 51 is fixedly installed on the second traction hook 52. The second traction rope 51 is inclinedly installed on the combined gangway component 1, and a traction machine is fixedly installed at the top of the second traction rope 51.

[0040] It should be noted that the towing machine is fixedly installed on the ship, and the length of the towing machine's towing arm is less than the distance between the towing machine base and the side of pedal 11. That is, when the towing machine is towing pedal 11, the towing rope 251 is as follows: Figure 6 As shown in the diagram, since the traction force of the second traction rope 51 is located on the right side of the pedal 11, the second traction rope 51 can assist in adjusting the posture of the pedal 11 during the process of pulling and lifting the pedal 11 by the first traction rope 34, so that the pedal 11 slowly returns to its original position against the side wall of the ship. Guiding the traction direction of the pedal 11 can prevent the pedal 11 from swaying left and right due to the radial force of the output end of the rotary drive 2.

[0041] Refer to the instruction manual appendix Figure 6 and Figure 7 During the rotation and reset process of pedal 11, a unidirectional auxiliary pulling force is provided to pedal 11 via traction rope 2 51 to prevent pedal 11 from swaying. However, the side of pedal 11 may come into contact with the hull of the ship. To avoid damage to the hull, the anti-collision mechanism 5 specifically includes a linear actuator 2 53. The linear actuator 2 53 is fixedly mounted on pedal 11, and a support base 531 is fixedly mounted on the output end of the linear actuator 2 53. A roller 54 is rotatably mounted on the support base 531. A groove is provided on the support base 531, and an adjusting seat 1 55 and an adjusting seat 2 56 are slidably mounted in the groove. An elastic element 57 is provided between the adjusting seat 1 55 and the adjusting seat 2 56. A fixed shaft is fixedly mounted on the roller 54, and the fixed shaft is slidably mounted in the groove. The fixed shaft is in contact with the adjusting seat 1 55. A pressure sensor 58 is fixedly mounted on the support base 531, and the acquisition end of the pressure sensor 58 is in contact with the adjusting seat 2 56.

[0042] It should be noted that the elastic element 57 is a spring, with its two ends fixedly mounted on the sides of the adjusting seat 1 55 and the adjusting seat 2 56, respectively, close to each other. The linear actuator 2 53 includes, but is not limited to, a hydraulic cylinder or a push rod motor. Multiple linear actuators 2 53 are mounted on the pedal 11, and each linear actuator 2 53 has a roller 54 and related components at its output end; that is, multiple sets of linear actuators 2 53 are provided. The pressure sensor 58 obtains the pressure parameters of the roller 54 by measuring the change in pressure of the object being measured, which causes a change in the inductance of the inductor coil. Its working principle is mature existing technology and will not be elaborated further here.

[0043] It should also be noted that when the traction rope 1 34 and traction rope 2 51 lift the pedal 11 to reset, the linear actuator 2 53 is activated. The moving drive roller 54 at the output end of the linear actuator 2 53 contacts the hull of the ship. When the roller 54 contacts the hull, it provides a reaction force to the adjusting seat 1 55. The reaction force pushes the adjusting seat 2 56 towards the acquisition end of the pressure sensor 58 through the elastic element 57. The acquisition end of the pressure sensor 58 obtains the pressure parameter. More precisely, when the acquisition end of the pressure sensor 58 obtains a pressure of 300N fed back by the roller 54, there is no need to adjust the moving position of the output end of the linear actuator 2 53. If the pressure sensor 58 receives a pressure less than this value from the roller 54, the output end of the linear actuator 2 53 then drives the support seat 531 to move towards the hull of the ship, ensuring that the rollers 54 on the output ends of multiple linear actuators 2 53 can all fit against the hull of the ship, making the pedal 11 more stable when resetting its posture and further improving the safety of the staff on the pedal 11.

[0044] Furthermore, through the cooperation of the linear actuator 2 53 and the roller 54, not only can support be provided between the pedal 11 and the ship's hull, ensuring that the pedal 11 maintains a stable posture during the rotation and reset process, but also, since the tilt angle of the ship's hull is not the same, through the cooperation of the pressure sensor 58 and the elastic element 57 and other components, the distance between the roller 54 and the ship's hull can be adaptively adjusted according to the changes in the tilt angle of the ship's hull at different heights, ensuring that the distance between the pedal 11 and the ship's hull is always the same, thereby further improving the stability of the pedal 11 during the posture reset process.

[0045] Working principle: Initially, pedal 11 is horizontally positioned on the ship. When the gangway needs to be lowered for personnel use, rotary actuators 2 and 3 are activated. The output of rotary actuator 2 rotates and unwinds the traction rope 34. The output of rotary actuator 2 drives pedal 11 to rotate around the center of the output of rotary actuator 2. This, combined with the unwinding of the traction rope 34, tilts pedal 11, thus adjusting its posture. Once pedal 11 is adjusted to the desired posture, the output of rotary actuator 2 and the winding roller 33 stop rotating, ensuring pedal 11 maintains its corresponding posture. By connecting ball joint 41 and fixed seat 42, when rotary actuator 2 rotates, connecting shaft 43 engages in sliding groove 421. Connecting shaft 43, in conjunction with sliding groove 421, drives fixed seat 42 to rotate synchronously, allowing rotary actuator 2 and traction rope 34 to adjust the tilt of pedal 11. If pedal 11 is tilted and the waves are large, causing radial pressure between pedal 11 and the drive end of rotary actuator 2, the sliding groove 421 and the connecting shaft 43 can cause an angular deflection between pedal 11 and the drive end of rotary actuator 2. This prevents damage caused by radial force between pedal 11 and the drive end of rotary actuator 2 due to their fixed installation. In other words, it allows pedal 11 and the drive end of rotary actuator 2 to not be in a perpendicular state. The towing machine is fixedly installed on the ship, and the length of the towing machine's towing arm is less than the distance between the towing machine base and the side of pedal 11. That is, when the towing machine tows pedal 11, the towing rope 2 51... Figure 6As shown in the diagram, since the traction force of the second traction rope 51 is located on the right side of the pedal 11, the second traction rope 51 can assist in adjusting the posture of the pedal 11 during the process of pulling and lifting the pedal 11 by the first traction rope 34, so that the pedal 11 slowly returns to its original position against the side wall of the ship. Guiding the traction direction of the pedal 11 can prevent the pedal 11 from swaying left and right due to the radial force of the output end of the rotary drive 2. When the traction rope 1 34 and traction rope 2 51 lift the pedal 1 11 to reset, the linear actuator 2 53 is activated. The moving drive roller 54 at the output end of the linear actuator 2 53 contacts the hull of the ship. When the roller 54 contacts the hull, it provides a reaction force to the adjusting seat 1 55. The reaction force pushes the adjusting seat 2 56 towards the acquisition end of the pressure sensor 58 through the elastic element 57. The acquisition end of the pressure sensor 58 obtains the pressure parameter. More precisely, when the acquisition end of the pressure sensor 58 obtains a pressure of 300N fed back by the roller 54, there is no need to adjust the moving position of the output end of the linear actuator 2 53. If the pressure sensor 58 receives a pressure less than this value from the roller 54, the output end of the linear actuator 2 53 then drives the support seat 531 to move towards the hull of the ship, ensuring that the rollers 54 on the output ends of multiple linear actuators 2 53 can all fit against the hull of the ship, making the pedal 1 11 more stable when resetting its posture and further improving the safety of the staff on the pedal 1 11.

[0046] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
