Description

Technical Field

[0001] The utility model relates to the technical field of ship equipment, and particularly relates to an open-type gangway body structure and a ship. Background Art

[0002] For ships transporting or carrying vehicles, the passage system is generally arranged on the side or the tail of the ship. Its main function is to open the gangway by means of a hydraulic and electrical system after the ship arrives at the port so that the gangway can be placed on the dock for vehicles to pass through smoothly. The passage system mainly consists of an opening in the outer plate on the side or the tail of the ship and a doorframe, a gangway body structure covering the opening and the doorframe, and an opening and closing device for operating the gangway.

[0003] When the ship approaches the dock, the opening and closing device of the gangway is operated to open the gangway. The gangway body connects the dock and the hull, and vehicles can enter the hull through the gangway body. In the prior art, the gangway body structure mostly adopts a downward-opening structure. For example, the utility model with the publication number CN203714133U and the invention name of a stern door of a trimaran passenger and cargo ship serving as a gangway discloses a stern door structure serving as a gangway. The stern door structure is closed during navigation. The back of the main gangway is provided with longitudinal girders 9 and transverse ribs 10 arranged vertically and horizontally, which are used to support the fastening device and increase the stiffness of the gangway to meet the vehicle passing requirements. As shown in the structural schematic diagram of the closed stern door in the attachment Figure 1 When the longitudinal girders 9 and the transverse ribs 10 are exposed and arranged towards the outside of the hull, the longitudinal girders 9 and the transverse ribs 10 are continuously eroded by wind and waves when the ship is in a navigation state, which is likely to cause corrosion of the main gangway and a decrease in strength, increasing the maintenance and repair costs. At the same time, for some special ship types, it is required that the outer plate of the ship is flush, and the consistency between the gangway and the hull is maintained. The open-type structure of the gangway cannot meet the requirement of the consistency between the gangway and the hull and needs to be improved. Content of the Utility Model

[0004] The purpose of the utility model is to provide an open-type gangway body structure and a ship, which can effectively reduce the erosion hazard of the external environment to the gangway body and meet the requirement of the consistency between the gangway body and the hull at the same time.

[0005] To solve the above technical problems, an embodiment of the utility model provides a technical solution as follows:

[0006] An open-type gangway body structure includes a base plate. A plurality of support beams and reinforcing beams are fixedly arranged on the upper surface of the base plate. A plurality of anti-slip plates are detachably and fixedly arranged at one end of the support beam away from the base plate.

[0007] Furthermore, a support frame is arranged between the support beam and the anti-slip plate. The support frame is fixedly connected to one end of the support beam away from the base plate, and the anti-slip plate is detachably and fixedly connected to the support frame.

[0008] Further, the support frame includes a frame and a plurality of through avoidance holes defined by the frame, and the edge portion of the anti-slip plate is detachably and fixedly connected to the frame.

[0009] Further, the support beam includes a first support beam arranged in parallel and spaced apart and a second support beam arranged perpendicular to the first support beam.

[0010] Further, one or more reinforcing beams are provided between two adjacent first support beams.

[0011] Further, the reinforcing beam is arranged parallel to the first support beam.

[0012] Further, the support beam and the reinforcing beam are both perpendicular to the substrate, and the height of the reinforcing beam in the direction perpendicular to the substrate is less than the height of the reinforcing beam.

[0013] Further, the support beam is a T-shaped steel or an I-shaped steel, and the transverse end surface of the support beam is detachably and fixedly connected to the anti-slip plate.

[0014] Further, anti-slip members protrude from the surface of the anti-slip plate away from the substrate.

[0015] To solve the above technical problems, the present invention also provides a ship, including a hull and a gangway group movably connected to one side of the hull. An actuating device is provided between the hull and the gangway group, and the gangway group includes the open gangway body structure as described in any one of the above.

[0016] For the open gangway body structure and the ship provided by the present invention, compared with the open gangway body structure in the prior art, by arranging the support beam and the reinforcing beam on the upper surface of the substrate and detachably arranging a plurality of anti-slip plates on the upper surface of the support beam, it can effectively meet the function of vehicle passing and the load requirements of the gangway body, and can also effectively reduce the erosion damage of the external environment such as wind and wave impact on the gangway body. At the same time, when the gangway group is in the closed state, the lower surface of the substrate can be flush with the outer plate of the ship, meeting the requirements of the consistency between the gangway body and the hull.

Detailed implementation manners

[0027] To make the objectives, technical solutions and advantages of the present utility model clearer, the following will elaborate on the various embodiments of the present utility model with reference to the accompanying drawings. However, those of ordinary skill in the art can understand that in the various embodiments of the present utility model, many technical details are presented for the purpose of enabling the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed in the various claims of the present application can still be implemented.

[0028] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present application, such directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If this specific posture changes, then the directional indications will also change accordingly.

[0029] Such as Figures 1-3As shown in the figure, in an embodiment provided by the present utility model, a ship is involved. The ship includes a hull 1 and a gangway group 2 provided on one side of the hull 1. The gangway group 2 includes a connecting frame 10 and a gangway body 20 fixedly connected to the connecting frame 10. One end of the connecting frame 10 is hinged to the hull 1, and a tongue plate 30 is further connected to the other end. An actuating device 3 is provided between the gangway group 2 and the hull 1. The gangway group 2 can be driven to move closer to or away from the hull 1 through the actuating device 3. When the gangway group 2 is opened, under the action of the actuating device 3, the gangway group 2 moves away from the hull 1 to a set position; when the gangway group 2 is closed, under the action of the actuating device 3, the gangway group 2 moves closer to the hull 1 until the set position. When the gangway group 2 is in a fully closed state, that is, when the gangway group 2 moves to the set position of the closing action, the outer surface of the gangway group 2 is flush with the outer surface of the hull 1.

[0030] As Figures 4-8 As shown in the figure, the first embodiment of the present utility model relates to a structure of an open gangway body 20, including a rigid substrate 21. A plurality of support beams 22 and reinforcing beams 23 are fixedly arranged on the upper surface of the substrate 21. The support beams 22 and the reinforcing beams 23 are arranged in a staggered manner. A support frame 24 is fixedly arranged on the upper surface of the support beam 22. The support frame 24 is a hollow structure. The support frame 24 includes a frame 242 and a plurality of through avoidance holes 241 defined by the frame 242. A plurality of anti-slip plates 25 are arranged on the support frame 24. The anti-slip plates 25 correspond to the avoidance holes 241 one by one. The edge portion 251 of the anti-slip plate 25 is detachably fixedly connected to the frame 242 of the support frame 24. In an exemplary instance, the edge portion 251 of the anti-slip plate 25 is fixedly connected to the frame 242 of the support frame 24 by bolts.

[0031] In an embodiment, a structure of an open gangway body 20 is involved. The support beam 22 includes a first support beam 221 arranged in parallel and spaced apart and a second support beam 222 arranged perpendicular to the first support beam 221. The support beam 22 is a steel plate and is arranged perpendicular to the surface of the substrate 21. One or more reinforcing beams 23 are arranged in parallel between two adjacent support beams 22. The reinforcing beam 23 is a steel plate and is arranged perpendicular to the surface of the substrate 21. Preferably, the height of the reinforcing beam 23 in the direction perpendicular to the substrate 21 is less than the height of the support beam 22, that is, the upper surface of the reinforcing beam 23 is lower than the upper surface of the support beam 22, and the upper end of the reinforcing beam 23 does not contact the support frame 24. The arrangement of the support beam 22 and the reinforcing beam 23 can effectively increase the strength and stiffness of the substrate 21, improve the load-bearing capacity of the gangway body 20 structure. At the same time, the setting of reducing the height of the reinforcing beam 23 helps to reduce the weight of the gangway body 20 structure and reduce the manufacturing cost.

[0032] In one embodiment, it relates to a structure of an open-type gangplank body 20. A plurality of anti-slip plates 25 are laid on the support frame 24 in an isolated manner and are detachably connected to the support frame 24. An anti-slip member 252 is provided on the upper surface of the anti-slip plate 25 facing away from the support frame 24. The anti-slip member 252 protrudes from the upper surface of the anti-slip plate 25. The anti-slip member 252 can be integrally formed with the anti-slip plate 25 or can be fixedly connected after being separately processed. The anti-slip member 252 can be arranged in a variety of ways, such as parallel arrangement, fishbone-shaped arrangement, etc.

[0033] In one embodiment, it relates to a structure of an open-type gangplank body 20. The structure of the gangplank body 20 includes a base plate 21, and a plurality of support beams 22 and reinforcing beams 23 that are alternately and fixedly arranged on the upper surface of the base plate 21. The support beams 22 and the reinforcing beams 23 are perpendicular to the base plate 21. The height of the reinforcing beam 23 in the direction perpendicular to the base plate 21 is less than the height of the support beam 22. The support beam 22 includes a first support beam 221 arranged in parallel and spaced apart, and a second support beam 222 perpendicular to the first support beam 221. The support beam 22 is a T-shaped steel. The lower end face of the T-shaped steel in the vertical direction is fixedly connected to the base plate 21. A plurality of anti-slip plates 25 are detachably laid on the upper end face of the T-shaped steel in the horizontal direction. The edge of the anti-slip plate 25 is fixedly connected to the upper end face of the support beam 22 by bolts. In an exemplary example, the support beam 22 is an I-shaped steel. A plurality of anti-slip plates 25 are laid on the lateral end face of the support beam 22 away from the base plate. The anti-slip plates 25 are arranged in an isolated manner. The edge portion 251 of the anti-slip plate 25 forms a detachable fixed connection with the upper end face of the support beam 22 away from the base plate 21 through bolts.

[0034] For a structure of an open-type gangplank body 20 provided by the present utility model, when the gangplank group 2 is closed, the side of the base plate 21 in the gangplank group 2 facing the inside of the hull 1 is the upper surface, and the side facing the outside of the hull 1 is the lower surface. When manufacturing the gangplank body 20, first, the support beams 22 and the reinforcing beams 23 are welded and fixed on the upper surface of the base plate 21. The support beam 22 can be selected as a flat steel plate, or a T-shaped steel or an I-shaped steel can be used. When the support beam 22 is selected as a flat steel plate, a support frame 24 is fixedly connected to the end of the support beam 22 away from the base plate 21, and then the anti-slip plate 25 is detachably fixed on the support frame 24; when the support beam 22 is selected as a T-shaped steel or an I-shaped steel, the anti-slip plate 25 can be directly detachably fixed on the end face of the support beam 22 away from the base plate 21; the anti-slip plates 25 are combined and arranged according to the layout of the support beams 22. Each anti-slip plate 25 can be individually disassembled and installed, which is more convenient for construction and is beneficial to reducing the construction cost.

[0035] The open-type gangway body structure and ship provided by the utility model, compared with the open-type gangway body structure in the prior art, by arranging the support beam and the reinforcement beam on the upper surface of the substrate, and detachably arranging a plurality of anti-slip plates on the upper surface of the support beam, can effectively meet the function of vehicle passing and the load requirement of the gangway body, and can also effectively reduce the erosion hazard of the external environment such as wind and wave impact on the gangway body. At the same time, when the gangway group is in the closed state, the lower surface of the substrate can be flush with the outer hull of the ship, meeting the requirement of the consistency between the gangway body and the hull.

[0036] Those of ordinary skill in the art can understand that the above embodiments are specific embodiments for implementing the present invention, and in practical applications, various changes can be made to them in form and details without departing from the spirit and scope of the present invention.
