Description

Technical Field

[0001] The invention belongs to the technical field of ships, and in particular relates to an adjustable ship boarding platform. Background Art

[0002] As the global shipping industry is booming, the operational efficiency and safety of ships are receiving more and more attention. Ships frequently depart and dock at various ports, and the boarding platform is a key connection facility for people and materials to get on and off the ship. Its performance is directly related to the smoothness and reliability of the entire shipping process.

[0003] At the same time, the patent specification with application number CN205345279U discloses an offshore platform boarding device, "including a basic platform, a rotating platform, a lifting mechanism, a boarding ladder, a power hydraulic system and an electrical control system. The basic platform is fixed on the offshore platform, and the rotating platform is installed on the basic platform through a rotating support. The lifting mechanism is composed of a winch, a steel cable, a boom and a guide pulley set arranged on the upper surface of the boom. The lifting mechanism enables the boarding ladder to achieve an angle amplitude of -60 to +30 degrees in the vertical direction; the boarding ladder is composed of a main ladder, a telescopic ladder and a boat ladder. The purpose is to be used when the ship and the offshore platform cannot approach each other";

[0004] Existing ship boarding devices are usually fixed structures, and their angles cannot be flexibly adjusted. Different ships have different boarding ports at different heights, which results in poor adaptability of existing fixed structures when facing various ship types and docking scenarios. They can only be used under specific conditions and have a very limited scope of application. Secondly, in the horizontal direction, there is a lack of adjustable extension or shortening mechanisms and effective buffering and shock-absorbing structures. Although the ship is fixed by cables when docked, it will inevitably shake when the wind blows. At this time, the boarding platform carried on the boarding port shakes with the ship, making it difficult for the boarding device to accurately dock with boarding ports at different offshore distances. It is often necessary to build additional temporary auxiliary facilities to make up for this deficiency. The operation is cumbersome and consumes manpower and material resources.

[0005] Therefore, in view of the above problems, an adjustable ship embarkation platform is proposed. Summary of the invention

[0006] In order to solve the problems raised in the above-mentioned background technology, the present invention provides an adjustable ship boarding platform, which has a boarding port that can be used for different heights and distances from the shore, has a wide range of applications, strong stability, a simple and reliable structure, can be extended and shortened within a certain range in the horizontal direction, has good flexibility, and is not easily damaged when the ship shakes.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] The adjustable ship boarding platform comprises a bottom platform, the inner surface of the bottom platform is rotatably connected to an inclined walkway, the side of the inclined walkway away from the inner surface of the bottom platform is fixedly connected to a top platform, one end of the bottom platform and the top platform are slidably sleeved with a sliding frame, the bottom ends of the two sliding frames are fixedly connected to a sliding platform, the bottom ends of the top platform and the bottom platform are fixedly connected to an outer supporting platform and an inner supporting platform, one end of the two outer supporting platforms are provided with a through groove, the two sliding frames are slidably sleeved with two through grooves respectively, the outer supporting platform and the inner supporting platform are distributed in parallel, the corresponding outer supporting platform and the inner supporting platform are commonly fixedly connected with two sliding rods, and the inner surfaces of the two sliding platforms are slidably sleeved with the two sliding rods respectively.

[0009] Preferably, the bottom platform, the top platform and the top of the inclined walkway are all fixedly connected with guardrails, the lower inner wall of the inclined walkway is provided with boarding steps, and the outer surface of the boarding steps is provided with an anti-slip coating.

[0010] Preferably, springs are wound around the outer surfaces of the four sliding rods, and the ends of the corresponding sliding platforms opposite to the outer supporting platforms are fixedly connected to the two springs.

[0011] Preferably, the bottom platform is rotatably connected to the inclined walkway via a pin shaft.

[0012] Preferably, inner surfaces of the two sliding frames are fixedly connected with support members, and one end of the two sliding frames is provided with a mounting frame.

[0013] Preferably, both ends of the inclined walkway are fixedly connected with slideways, the outer surfaces of the two slideways are slidably sleeved with sliders, both ends of the bottom platform are fixedly connected with hydraulic rods, and the output ends of the two hydraulic rods are rotatably connected to one end of the two sliders respectively.

[0014] Preferably, both ends of the two slideways are fixedly connected to limit blocks.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention is connected with the inclined walkway by rotation of the bottom platform, and the slideways and sliders at both ends of the inclined walkway are linked with the hydraulic rods of the bottom platform. Under the telescopic action of the hydraulic rods, the inclination angle of the inclined walkway can be accurately adjusted, so that the device can be used for boarding gates at different heights, with a wide range of applications, strong stability, and a simple and reliable structure.

[0017] 2. The elastic sliding buffer structure composed of a sliding frame, a sliding platform, a sliding rod and a spring is used in the present invention. Under the external force generated by the shaking of the ship, the sliding frame slides on the sliding rod, and the spring expands and contracts in time to buffer, effectively absorbing and dispersing the impact force generated by the shaking. The device can be extended and shortened within a certain range in the horizontal direction, and has good flexibility, so that the device can be extended and shortened within a certain range in the horizontal direction, and can accurately dock with boarding ports at different offshore distances. There is no need to build cumbersome temporary auxiliary facilities, saving manpower and material resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figures 1 to 4As shown, the present invention provides an adjustable ship boarding platform, including a bottom platform 2, the inner surface of the bottom platform 2 is rotatably connected with an inclined walkway 1, the bottom platform 2 is rotatably connected to the inclined walkway 1 through a pin shaft, and the side of the inclined walkway 1 away from the inner surface of the bottom platform 2 is fixedly connected with a top platform 6. The main structure composed of the bottom platform 2, the inclined walkway 1 and the top platform 6 provides a walking passage for personnel, adapts to the height difference and space layout requirements between the ship and the dock, enables boarding operations to be carried out in an orderly manner, and ensures the realization of the basic functions of personnel getting on and off the ship. One end of the bottom platform 2 and the top platform 6 are both slidably sleeved with a sliding frame 27, and the bottoms of the two sliding frames 27 are The ends are fixedly connected with slides 24, the bottom ends of the top platform 6 and the bottom platform 2 are fixedly connected with outer support platforms 21 and inner support platforms 25, one end of the two outer support platforms 21 is provided with through grooves 26, and the two slide frames 27 are respectively slidably sleeved with the two through grooves 26, the outer support platforms 21 and the inner support platforms 25 are distributed in parallel, and the corresponding outer support platforms 21 and the inner support platforms 25 are commonly and fixedly connected with two slide bars 22, the inner surfaces of the two slide platforms 24 are respectively slidably sleeved with the two slide bars 22, by arranging the slide bars 22 and the slide frames 27, the device can be extended and shortened within a certain range in the horizontal direction, and can accurately dock with boarding ports at different offshore distances.

[0026] Specifically, the bottom platform 2, the top platform 6 and the top of the inclined walkway 1 are all fixedly connected with a guardrail 4, the lower inner wall of the inclined walkway 1 is provided with a boarding step 5, and the outer surface of the boarding step 5 is provided with an anti-skid coating, the guardrail 4 provides lateral protection for personnel during the boarding process, and the boarding step 5 facilitates personnel to walk, especially in the case of a certain tilt angle, providing a stable stepping support. The anti-skid coating further enhances the friction of the step surface, and can effectively reduce the possibility of personnel slipping even in the case of moisture, water stains or ship shaking causing personnel to have unstable steps.

[0027] like Figures 1 to 4 As shown, the outer surfaces of the four slide bars 22 are all wound with springs 23, and the ends of the corresponding slide platforms 24 opposite to the outer support platforms 21 are fixedly connected to the two springs 23. The springs 23 are sleeved on the slide bars 22 to increase their stability, and can also disperse energy through telescopic deformation, thereby reducing the rigid impact on the overall structure of the platform, thereby reducing the risk of structural damage, extending the service life of the boarding platform, and providing personnel with a relatively smooth and comfortable boarding experience.

[0028] Furthermore, the inner surfaces of the two sliding frames 27 are fixedly connected with support members 28, and one end of the two sliding frames 27 is provided with a mounting frame 3. The support members 28 enhance the structural strength and stability of the sliding frames 27, making it less likely to be deformed or damaged when subjected to large external forces. The mounting frame 3 provides a convenient interface for connecting the boarding platform with the ship or dock.

[0029] like Figures 1 to 4 As shown, both ends of the inclined walkway 1 are fixedly connected with slideways 12, and the outer surfaces of the two slideways 12 are slidably sleeved with sliders 13, and both ends of the bottom platform 2 are fixedly connected with hydraulic rods 11, and the output ends of the two hydraulic rods 11 are rotatably connected to one end of the two sliders 13 respectively. By setting the hydraulic rods 11, the lifting and angle change of the inclined walkway 1 can be accurately controlled to achieve automated and precise adjustment operations to meet different boarding requirements. Both ends of the two slides 12 are fixedly connected with limit blocks 14, and the limit blocks 14 limit the sliding range of the slider 13 to prevent the slider 13 from excessively sliding on the slideway 12 and causing the structure to detach or be damaged, thereby ensuring that the entire angle adjustment mechanism operates within a safe and reliable range.

[0030] Among them, the hydraulic rod 11 is a prior art and will not be described in detail; at the same time, the present invention also includes a power supply, a controller and a switch, which are not the main technical points of this patent and will not be described in detail. The wiring diagram of the motor in the present invention belongs to the common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use, so the control method and wiring layout of the motor are not explained in detail.

[0031] Working principle and process: When the boarding platform angle needs to be adjusted, first open the hydraulic rods 11 at both ends of the bottom platform 2. The hydraulic rods 11 extend and retract to push the sliders 13 to move on the slides 12 at both ends of the inclined walkway 1. As the position of the sliders 13 changes, the inclined walkway 1 will rotate around the pin connection point between the bottom platform 2 and the inclined walkway 1, thereby achieving precise adjustment of the angle, so that the top platform 6 can better dock with the ship's boarding port. When adjusted to a suitable angle, close the hydraulic rods 11. When the ship shakes after berthing, whether it is swaying in the horizontal direction or rising and falling in the vertical direction, the bottom platform 2 and the top platform 6 will produce displacement changes with the shaking of the ship. At this time, the sliding frame 27 slides on the bottom platform 2 and the top platform 6, and the slide 24 at the bottom of the sliding frame 27 performs corresponding linear movement along the slide rod 22. The spring 23 will be stretched or compressed as the slide 24 moves. The spring 23 absorbs and buffers the impact force generated by the shaking of the ship through its own elastic deformation, effectively avoiding damage caused by the impact force directly acting on the platform structure, maintaining the stability of the overall structure of the platform, and ensuring that personnel can board or leave the ship on the platform relatively safely and smoothly.

[0032] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
