Description

Technical Field

[0001] This invention relates to the field of boarding board technology, specifically a stable wave-compensating boarding board for boarding at sea. Background Technology

[0002] Boarding ramps connect docks and vessels, facilitating safe boarding and disembarking for personnel. Spanning the ship's side and the shoreline, they provide a stable passageway, preventing slips and falls due to gaps, swaying, or wetness. Commonly found on cruise ships, ferries, and workboats, they are crucial auxiliary facilities ensuring the safety of passengers and crew. Because ships continuously rise, fall, and roll in waves, the hooks on the deck and boarding ramp constantly shift relative to the target object. Therefore, wave compensation is needed to maintain the stability of the load space and ensure safe and precise offshore lifting, resupply, or personnel boarding. (Example: Application No. 202111111503.2, application date 2021-) Chinese invention patent application No. 09-23 discloses a boarding ladder with wave compensation function, which can be flexibly adjusted and effectively compensates for waves, greatly improving the stability of the boarding ladder in windy and wavy environments; and Chinese utility model patent application No. 201620913648.2, filed on August 22, 2016, discloses a passive wave compensation boarding device, which has the advantages of simple operation, high work efficiency, wide application range, safety and reliability, high degree of automation, low labor cost, and convenient transportation.

[0003] During prolonged use, the humid water environment and salt spray corrosion can cause the boarding board's rotating shaft to rust, become stuck, and rotate inflexibly. Therefore, lubrication is necessary during use. Without an efficient lubrication system, the lack of continuous lubrication will increase dry friction on the boarding board's rotating shaft, causing scratches and pitting on the surface, reducing rotational flexibility, shortening the lifespan of parts, and increasing maintenance frequency and costs. Summary of the Invention

[0004] The purpose of this invention is to provide a stable wave-compensated boarding ramp for sea boarding, in order to solve the problems mentioned in the background art, such as the lack of efficient lubrication components, which leads to increased dry friction on the boarding ramp's rotating shaft due to lack of continuous lubrication, resulting in scratches and pitting on the surface, reduced rotational flexibility, shortened service life of parts, and increased maintenance frequency and cost.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a wave-compensating gangway for stable boarding at sea, comprising an equipment box and a gangway body. A working box is movably disposed inside the equipment box, and a front telescopic rod is movably connected to the front side of the working box via a fixed plate. The output end of the front telescopic rod is movably connected to the bottom of the gangway body. A working block is fixedly connected to the upper surface of the working box, and a rotating shaft is rotatably disposed inside the working block. The surface of the rotating shaft is fixedly connected to the gangway body via a sleeve. A compensation component is also disposed between the equipment box and the working box, and a sensor controller is disposed on the inner wall of the equipment box. A material box is fixedly connected to the inner wall of the equipment box, and its interior is connected to the working block via a lubrication component. A pressing plate is slidably disposed inside the material box. A movable gangway is connected to the material box via a lifting component, and a locking plate is slidably disposed inside the movable gangway. An upper connecting plate is fixedly connected to the upper surface of the pressing plate, and an auxiliary pressing component is disposed between the upper connecting plate and the locking plate. The auxiliary pressing component keeps the pressing plate in constant contact with the oil surface.

[0006] Preferably, a back plate is fixedly connected to the back of the work box, the compensation component includes an electric telescopic rod movably connected to the inner wall of the equipment box, the electric telescopic rods are evenly distributed inside the equipment box, and the output end of the electric telescopic rod is movably connected to the back plate. A sensor is provided on the inner wall of the equipment box and is electrically connected to the electric telescopic rod.

[0007] With the above structure, when the sensor is working, the electric telescopic rod is controlled to work, and the wave compensation of the back plate and the working box is performed by adjusting the electric telescopic rod.

[0008] Preferably, an inner plate is fixedly connected to the inner wall of the equipment box, and a motor is bolted to the surface of the inner plate. A connecting shaft is fixedly connected to the output end of the motor, and a traction rope is wound and fixedly connected to the surface of the connecting shaft.

[0009] With the above structure, the sensor and motor are connected by electrical signals. When compensation is performed, the motor also starts, and the release and retraction of the traction rope plays an auxiliary compensation role.

[0010] Preferably, a docking block is fixedly connected to the upper surface of the work box, and a docking rod is provided inside the docking block, with the traction rope fixedly connected to the docking rod.

[0011] With the above structure, the traction rope works in conjunction with the docking block and docking rod during operation, providing efficient auxiliary compensation.

[0012] Preferably, the lifting assembly includes a push plate fixedly connected to the end of the connecting shaft, and the end of the push plate is arc-shaped, and the right side of the push plate is an inverted "V" shape. In addition, a limit plate is fixedly connected to the inner wall of the material box.

[0013] With the above structure, when the motor is working, it drives the push plate to work. The right side of the push plate is viewed as an inverted "V" shape, so no matter which direction the push plate rotates, it will push the movable plate.

[0014] Preferably, the right side of the limiting plate is an inverted "L" structure, and the movable plate is slidably disposed on the surface of the limiting plate, and the movable plate is located at the upper end of the extrusion plate. In addition, the movable plate and the limiting plate are connected by a return spring.

[0015] Limiting rods are fixedly connected to both sides of the upper end of the extrusion plate, and the limiting rods are slidably disposed inside the movable plate.

[0016] With the above structure, when the movable plate is pushed, it will move vertically, which in turn drives the extrusion plate to descend, extruding the lubricating oil and allowing it to enter the working block to lubricate the rotating shaft.

[0017] Preferably, a feeding pipe is fixedly connected to the outer wall of the material box, and the material box is connected to the working block through a conveying pipe. A slide is provided inside the working block. In addition, a one-way valve is provided on the surface of both the feeding pipe and the conveying pipe.

[0018] With the above structure, when the moving plate and the extrusion plate are working, the one-way valve ensures that the flow direction of the lubricating oil is from the material box to the working block, and there will be no backflow.

[0019] Preferably, the auxiliary extrusion assembly includes an auxiliary plate fixedly connected to the surface of the upper plate, and a long pin is rotatably provided inside the auxiliary plate, and a force-bearing plate is fixedly connected to the surface of the long pin, and the force-bearing plates are evenly distributed on the surface of the upper plate.

[0020] With the above structure, the equally spaced load-bearing plates ensure that the load-bearing plates remain in contact with the oil surface during operation.

[0021] Preferably, the force-bearing plate is inclined upwards, and the surface of the force-bearing plate has an arc-shaped structure, and the end of the long pin is protruding. In addition, a positioning rod is fixedly connected to the outer wall of the auxiliary plate.

[0022] The surface of the card plate is inclined downwards, and a torsion spring is fixedly connected to the surface of the long pin, with the other side of the torsion spring fixedly connected to the inner wall of the auxiliary plate.

[0023] Through the above structure, the positioning rod and the protrusion at the end of the long pin cooperate to limit the rotation angle of the long pin, so that the stress plate is always in the optimal stress state.

[0024] Preferably, an inner rod is fixedly connected to the inner wall of the movable plate, and a connecting plate is slidably disposed on the surface of the inner rod. The card plate is fixedly connected to the lower surface of the connecting plate. In addition, a connecting spring is connected between the connecting plate and the movable plate.

[0025] With the above structure, when it is necessary to add new lubricating oil into the material box, first pull the connecting plate and the clamping plate so that the clamping plate no longer presses against the force plate, and then the upper connecting plate can be pulled up. At this time, the space at the bottom of the material box is released, and lubricating oil can be added through the feeding pipe. After the connecting plate is released, the connecting plate drives the clamping plate to reset under the action of the connecting spring.

[0026] Compared with the prior art, the beneficial effects of this invention are as follows: Adopting a novel structural design, during wave compensation, a sensor controls the electric telescopic rod, enabling the working box to perform wave compensation under the action of the electric telescopic rod. The motor and traction rope provide depth compensation. Simultaneously, during this process, the lubricating oil inside the material box is pushed into the working block by the extrusion plate, lubricating the rotating shaft and extending its service life. The specific details are as follows:

[0027] (1) The stable wave compensation gangway for boarding at sea integrates a gyroscope and an accelerometer inside the sensor when performing wave compensation. The gyroscope measures the angular velocity of the hull around the three axes, and the accelerometer measures the acceleration of the three axes. Through fusion algorithms such as Kalman filtering, the data of the two are combined to calculate the real-time attitude parameters such as roll, pitch and heave. Then the sensor controls the electric telescopic rod, so that the work box can be extended or retracted as needed by the electric telescopic rod, and the angle of the back plate can be quickly adjusted, which plays the role of wave compensation.

[0028] Furthermore, when the electric telescopic pole is in operation, the motor works synchronously. The motor realizes the winding and releasing of the traction rope through the connecting shaft, which plays an auxiliary role in adjusting the posture and thus has the effect of depth compensation.

[0029] (2) When the connecting shaft rotates, the wave-compensating gangway of the sea boarding stabilizer will drive the push plate to rotate synchronously. When the push plate rotates, it pushes the movable plate. At this time, the movable plate and the extrusion plate descend. The extrusion plate extrudes the lubricating oil, so that the oil enters the working block through the delivery pipe, lubricating the shaft and extending the service life of the shaft.

[0030] Furthermore, during the movement of the movable plate, the limiting plate ensures that the movable plate moves only in the vertical direction, thus limiting its movement and ensuring the stability of the movable plate's operation.

[0031] (3) After the lubricating oil inside the material box is consumed, the lubricating oil will gradually decrease. At this time, the extrusion plate will drive the upper plate to descend under its own gravity. The force plate will not affect the normal descent of the extrusion plate under the action of the long pin and the torsion spring. That is, the extrusion plate will always be in contact with the oil surface. When the push plate and the movable plate are working, the movable plate will directly drive the extrusion plate to work through the clamping plate and the force plate. That is, no matter how much material is left inside the material box, it will be driven by the movable plate and transported to the working block, ensuring efficient lubrication and making the rotating shaft work stably.

[0046] 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.

[0047] Please see Figures 1-13 The present invention provides the following technical solution: a wave-compensated boarding ramp for stable boarding at sea.

[0048] Example 1: Includes equipment box 1 and plate 4. The equipment box 1 has a working box 2 movably installed inside. The front side of the working box 2 is movably connected to a front telescopic rod 3 through a fixed plate. The output end of the front telescopic rod 3 is movably connected to the bottom of the plate 4.

[0049] In the above technical solution, when the plate 4 needs to be adjusted to retract or extend, the front telescopic rod 3 can be activated. After receiving the command, the controller built into the front telescopic rod 3 changes the power supply polarity of the DC drive motor through a relay group or H-bridge circuit. When the power is applied in the forward direction, the drive motor rotates forward, and the rotary motion is converted into linear motion through the lead screw mechanism, and the push rod extends. When the power is applied in the reverse direction, the drive motor reverses and the push rod retracts. Limit switches and overcurrent protection are connected in series in the circuit to ensure safety. The speed of the entire process is regulated by PWM (pulse width modulation) signal to achieve smooth telescopic action. When the front telescopic rod 3 extends, the plate 4 rotates around the pivot 6 to open. When the front telescopic rod 3 retracts, the plate 4 retracts.

[0050] A working block 5 is fixedly connected to the upper surface of the working box 2, and a rotating shaft 6 is rotatably installed inside the working block 5. The surface of the rotating shaft 6 is fixedly connected to the plate 4 through a tube sleeve. A compensation component is also provided between the equipment box 1 and the working box 2, and a sensor controller is provided on the inner wall of the equipment box 1. A back plate 7 is fixedly connected to the back of the working box 2. The compensation component includes an electric telescopic rod 9 movably connected to the inner wall of the equipment box 1. The electric telescopic rod 9 is evenly distributed inside the equipment box 1, and the output end of the electric telescopic rod 9 is movably connected to the back plate 7. A sensor is provided on the inner wall of the equipment box 1 and is electrically connected to the electric telescopic rod 9.

[0051] In the above technical solution, during wave compensation, an attitude sensor is installed on the inner wall of the equipment box 1. The sensor integrates a gyroscope and an accelerometer. The gyroscope measures the angular velocity of the hull around three axes, and the accelerometer measures the acceleration along the three axes. Through fusion algorithms such as Kalman filtering, the data from both are combined to calculate real-time attitude parameters such as roll, pitch, and heave. Then, the gyroscope and accelerometer convert the sensed angular velocity and acceleration into weak capacitance or piezoresistive changes. After filtering and amplification, these changes are input to an analog-to-digital converter to become digital signals. Finally, the DSP or MCU calculates the attitude data through algorithms and outputs a PWM signal through PID control logic to drive the electric telescopic rod 9 to extend and retract for compensation. This quickly adjusts the angle between the back plate 7 and the working box 2, thus achieving the function of wave compensation.

[0052] An inner plate 10 is fixedly connected to the inner wall of the equipment box 1, and a motor 12 is bolted to the surface of the inner plate 10. A connecting shaft 13 is fixedly connected to the output end of the motor 12. In addition, a traction rope 14 is fixedly wound around the surface of the connecting shaft 13. A docking block 11 is fixedly connected to the upper surface of the work box 2, and a docking rod is provided inside the docking block 11. A traction rope 14 is fixedly connected to the docking rod.

[0053] In the above technical solution, when the electric telescopic pole 9 is working, the motor 12 on the surface of the inner plate 10 works synchronously. The motor 12 realizes the winding and releasing of the traction rope 14 through the connecting shaft 13, which plays an auxiliary role in adjusting the posture and thus has the effect of depth compensation.

[0054] Material box 8 is fixedly connected to the inner wall of equipment box 1, and the interior of material box 8 is connected to working block 5 through lubrication assembly. Extrusion plate 16 is slidably arranged inside material box 8. Movable plate 17 is connected to material box 8 through lifting assembly, and a clamping plate 27 is slidably arranged inside movable plate 17. Lifting assembly includes push plate 15 fixedly connected to the end of connecting shaft 13. The end of push plate 15 is arc-shaped, and the right side of push plate 15 is inverted "V" shape. In addition, limit plate 18 is fixedly connected to the inner wall of material box 8. The right side of limit plate 18 is inverted "L" structure, and movable plate 17 is slidably arranged on the surface of limit plate 18. Movable plate 17 is located above extrusion plate 16.

[0055] In the above technical solution, when the motor 12 drives the connecting shaft 13 to rotate, the connecting shaft 13 will drive the push plate 15 to rotate synchronously. When the push plate 15 rotates, it pushes the movable plate 17 (during the movement of the movable plate 17, the limiting plate 18 makes the movable plate 17 move only in the vertical direction, which plays a limiting role and ensures the stability of the movable plate 17). At this time, the movable plate 17 and the extrusion plate 16 descend, and the extrusion plate 16 extrudes the lubricating oil, so that the oil enters the working block 5 through the conveying pipe, flows to the position of the rotating shaft 6 through the slide, lubricates the rotating shaft 6, and plays a role in extending the service life of the rotating shaft 6.

[0056] The movable plate 17 and the limiting plate 18 are connected by a return spring 19; both sides of the upper end of the extrusion plate 16 are fixedly connected to limiting rods 22, and the limiting rods 22 are slidably arranged inside the movable plate 17; a feeding pipe 20 is fixedly connected to the outer wall of the material box 8, and the material box 8 is connected to the working block 5 through a conveying pipe; a slide is provided inside the working block 5; in addition, a one-way valve is provided on the surface of the feeding pipe 20 and the surface of the conveying pipe.

[0057] In the above technical solution, when the movable plate 17 and the pressing plate 16 descend, the return spring 19 is pressed. When the push plate 15 does not contact the movable plate 17, the movable plate 17 rises under the action of the return spring 19. When the movable plate 17 rises significantly, it will directly cooperate with the next force plate 25. When the movable plate 17 rises slightly, it will still cooperate with the current force plate 25 (when the movable plate 17 rises, the force plate 25 rises synchronously under the action of oil buoyancy), which facilitates the next use of the movable plate 17.

[0058] The upper plate 21 is fixedly connected to the upper surface of the extrusion plate 16, and an auxiliary extrusion assembly is provided between the upper plate 21 and the clamping plate 27. The auxiliary extrusion assembly keeps the extrusion plate 16 in contact with the oil surface. The auxiliary extrusion assembly includes an auxiliary plate 23 fixedly connected to the surface of the upper plate 21, and a long pin 24 is rotatably provided inside the auxiliary plate 23. A force plate 25 is fixedly connected to the surface of the long pin 24, and the force plates 25 are evenly distributed on the surface of the upper plate 21. The force plates 25 are inclined upwards, and the surface of the force plates 25 has an arc-shaped structure. The end of the long pin 24 is protruding. In addition, a positioning rod 26 is fixedly connected to the outer wall of the auxiliary plate 23. The surface of the clamping plate 27 is inclined downwards, and a torsion spring 31 is fixedly connected to the surface of the long pin 24. The other side of the torsion spring 31 is fixedly connected to the inner wall of the auxiliary plate 23.

[0059] In the above technical solution, after the lubricating oil inside the material box 8 is consumed, the lubricating oil will gradually decrease. At this time, the extrusion plate 16 will drive the upper connecting plate 21 to descend under its own gravity (the limit rod 22 makes the extrusion plate 16 move only in the vertical direction). The force plate 25, under the action of the long pin 24 and the torsion spring 31, will not affect the normal descent of the extrusion plate 16. That is, the extrusion plate 16 will always be in contact with the oil surface. When the push plate 15 and the movable plate 17 are working, the movable plate 17 will directly drive the extrusion plate 16 to work through the clamping plate 27 and the force plate 25. That is, no matter how much material is left inside the material box 8, it will be driven by the movable plate 17 and the extrusion plate 16 and transported to the working block 5, ensuring efficient lubrication and making the rotating shaft 6 work stably.

[0060] An inner rod 30 is fixedly connected to the inner wall of the movable plate 17, and a connecting plate 28 is slidably disposed on the surface of the inner rod 30. A clamping plate 27 is fixedly connected to the lower surface of the connecting plate 28. In addition, a connecting spring 29 is connected between the connecting plate 28 and the movable plate 17.

[0061] In the above technical solution, when it is necessary to add new lubricating oil to the material box 8, first pull the connecting plate 28 and the clamping plate 27 (the connecting plate 28 will slide on the surface of the inner rod 30, and the connecting spring 29 will be squeezed at the same time), so that the clamping plate 27 will no longer press against the force plate 25, and then the upper connecting plate 21 can be pulled up. At this time, the space at the lower end of the material box 8 is released, and lubricating oil can be added through the material supply pipe 20. After the connecting plate 28 is released, the connecting plate 28 drives the clamping plate 27 to reset under the action of the connecting spring 29, so that the clamping plate 27 can then drive the force plate 25 to work normally.

[0062] In addition, a sealing structure is provided between the extrusion plate 16 and the material box 8. A groove is opened on the outer periphery of the extrusion plate 16, and a lip-shaped sealing ring with the lip facing downward is installed. When the lip-shaped sealing ring moves downward, the lip is opened by the oil pressure and the oil pressure is established tightly against the wall. When it moves upward, oil is replenished through the replenishment pipe 20 at a slow speed, and it can be contacted by its own elasticity.

[0063] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0064] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
