Description

Technical Field

[0001] The invention relates to the technical field of ships, and in particular to a nail-type gangway connecting device for connecting a transfer barge and a floating pier. Background Art

[0002] Multi-module transfer barges serve as a storage and transfer base for offshore equipment and materials. They can be quickly deployed and floated in important sea areas or international waters. When offshore equipment and materials need to be transferred to island shores, ships have difficulty docking and landing due to the shallow draft and many obstacles on the beach. Therefore, they need to be extended to deep water areas through pier channels to transfer offshore equipment and materials. Most offshore pier channels are more than one kilometer long.

[0003] The transfer of offshore equipment and materials needs to be transferred to the island shore through the pier channel. Due to the requirement of rapid deployment of floating berths, most of the pier channels are floating piers. Although there is a gangway channel between the multi-module transfer barge and the pier channel, it is very dangerous to quickly transfer heavy-loaded equipment and materials on this gangway channel due to the marine environment, tidal changes and floating piers. In the special project "Floating Support Platform Project (Phase III)" of the Ministry of Industry and Information Technology's high-tech ship scientific research project, new research requirements were put forward for the offshore connection technology of complex configuration floating platforms.

[0004] Currently, there is no connector between the floating pier and the ship's gangway. Usually, the roll-on / roll-off transfer between the ship and the floating pier is mainly to first connect the ship and the pier with a soft connection through mooring rigging, and then use the gangway for roll-on / roll-off transfer. This form is only suitable for shore or when there is no sea condition. Roll-on / roll-off transfer through the gangway cannot be achieved offshore or in high sea conditions, and collisions may occur between the ship and the pier, causing damage. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the above-mentioned defects in the prior art and provide a nail-type gangway connecting device for connecting a transfer barge and a floating pier.

[0006] The present invention solves the above technical problems through the following technical solutions:

[0007] A nail-type gangway connecting device for connecting a transfer barge and a floating pier, comprising a gangway for connecting a first floating body and a second floating body, the gangway comprising a first gangway section arranged above the first floating body and a second gangway section hinged to the second floating body, the first gangway section being hinged to the second gangway section; the nail-type gangway connecting device for connecting the transfer barge and the floating pier also comprises a rivet member, a transverse slide arranged on the first gangway section and a longitudinal slide arranged on the first floating body; the notch of the transverse slide faces downward, and the notch of the longitudinal slide faces upward; the upper part of the rivet member is arranged in the transverse slide, and the lower part of the rivet member is arranged in the longitudinal slide; the inner wall of the transverse slide is provided with a transverse slide extending along the length direction of the transverse slide; the inner wall of the longitudinal slide is provided with a longitudinal slide extending along the length direction of the longitudinal slide; the upper part of the rivet member is fixedly provided with a first slider, and the lower part of the rivet member is fixedly provided with a second slider; the first slider is arranged in the transverse slide, and the second slider is arranged in the longitudinal slide.

[0008] The first floating body is a floating pier, and the second floating body is a transfer barge.

[0012] The two inner walls of the longitudinal slideway are each provided with a longitudinal slide groove, and the second sliding block is simultaneously arranged in the two longitudinal slide grooves.

[0013] The upper part and the lower part of the rivet part are both in the shape of a truncated cone, and the outer diameters of the top and the bottom of the rivet part are both smaller than the outer diameter of the middle part of the rivet part.

[0014] The width of the groove bottom of the transverse slide is smaller than the width of the notch of the transverse slide, and the width of the groove bottom of the longitudinal slide is smaller than the width of the notch of the longitudinal slide.

[0022] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a nail-type gangway connection device for connecting a transfer barge and a floating pier includes a gangway 10, which includes a first gangway section 11 arranged above the floating pier 80 and a second gangway section 12 hinged to the transfer barge 90, and the first gangway section 11 is hinged to the second gangway section 12.

[0024] The first ramp section 11 and the second ramp section 12 are connected via a first hinge 61 , and the second ramp section 12 is connected to the transfer barge 90 via a second hinge 62 .

[0025] The nail-type gangway connecting device for connecting the transfer barge and the floating pier also includes a rivet member 20, a transverse slide 30 provided on the first gangway section 11, and a longitudinal slide 40 provided on the floating pier.

[0026] The notch of the transverse slide 30 faces downward, and the notch of the longitudinal slide 40 faces upward.

[0027] The upper portion of the rivet member 20 is disposed in the transverse slideway 30 , and the lower portion of the rivet member 20 is disposed in the longitudinal slideway 40 .

[0028] The inner wall of the transverse slideway 30 is provided with a transverse slide groove 31 extending along the length direction of the transverse slideway; the inner wall of the longitudinal slideway 40 is provided with a longitudinal slide groove 41 extending along the length direction of the longitudinal slideway.

[0029] A first sliding block 51 is fixedly disposed on the upper portion of the rivet member 20 , and a second sliding block 52 is fixedly disposed on the lower portion of the rivet member 20 .

[0030] The first sliding block 51 is disposed in the transverse sliding groove, and the second sliding block 52 is slidably disposed in the longitudinal sliding groove.

[0031] The first slider 51 is annular and sleeved on the rivet 20. The second slider 52 is annular and sleeved on the rivet 20.

[0032] A transverse sliding groove 31 is respectively formed on the two inner walls of the transverse sliding track 30 , and the first sliding block 51 is disposed in the two transverse sliding grooves at the same time.

[0033] A longitudinal slide groove 41 is respectively formed on the two inner walls of the longitudinal slideway 40 , and the second sliding block 52 is disposed in the two longitudinal slide grooves 41 at the same time.

[0034] The upper and lower parts of the rivet member 20 are both truncated cone-shaped, and the outer diameters of the top and bottom of the rivet member are both smaller than the outer diameter of the middle part of the rivet member.

[0035] The width of the groove bottom of the transverse slide 30 is smaller than the width of the notch of the transverse slide 30. The width of the groove bottom of the longitudinal slide 40 is smaller than the width of the notch of the longitudinal slide 40.

[0036] The thickness of the first sliding block 51 is smaller than the slot width of the transverse sliding groove 31 . The thickness of the second sliding block 52 is smaller than the slot width of the longitudinal sliding groove 41 .

[0037] There is a gap between the rivet member 20 and the inner wall of the transverse slideway 30 and between the rivet member 20 and the inner wall of the longitudinal slideway 40 for the rivet member to rotate or slide.

[0038] The rivet member 20 can slide along the transverse slideway or rotate in the transverse slideway. The rivet member 20 can slide along the longitudinal slideway or rotate in the longitudinal slideway.

[0039] The first sliding block 51 can move along the transverse sliding groove, and the second sliding block 52 can move along the longitudinal sliding groove.

[0040] When the rivet member slides or rotates in the transverse slideway or the longitudinal slideway, the two ends of the first slider always remain in the two transverse slide grooves respectively, and the two ends of the second slider always remain in the two longitudinal slide grooves respectively.

[0041] When the floating trestle is stationary, the gangplank can rotate around the rivet. When the transfer barge is stationary (i.e., the gangplank is stationary), the floating trestle can rotate around the rivet. When both the floating trestle and the rotating barge are moving, the floating trestle and the rotating barge can rotate relative to each other around the rivet.

[0042] The gangway and the floating pier can move horizontally or vertically and rotate relatively to each other, which can offset the force generated by waves on the floating pier and the transfer barge in the aforementioned directions, avoid damage to the device due to excessive force, and thus extend the service life of the device.

[0043] When the transfer barge moves up and down due to the force of waves, and the floating pier moves up and down due to the force of waves, the hinged connection between the gangway and the transfer barge and the hinged connection between the first gangway section and the second gangway section can offset the force of the wave on the device, avoiding damage to the device due to excessive force, thus extending the service life of the device.

[0044] Since the first slider is always located in the transverse slide groove and the second slider is always located in the longitudinal slide groove, the gangway and the floating trestle can still be always connected during transverse movement, longitudinal movement or rotation between the gangway and the floating trestle, thereby preventing the gangway from being separated from the floating trestle.

[0045] When the gangway is used and needs to be folded, the second hinge can be loosened to separate the second gangway section from the transfer barge, and then the second gangway section is rotated around the first hinge to fold the second gangway section onto the first gangway. Then, the gangway is moved along the longitudinal slide to the position of the fixed gangway. Figure 4 shown.

[0046] When it is necessary to connect the gangway on the floating pier with the transfer barge, the second gangway section is rotated around the first hinge, and the end of the second gangway section is hinged with the transfer barge through the second hinge. In this way, the floating pier and the transfer barge can be connected quickly and reliably.

[0047] The present invention can realize fast, convenient and reliable docking between the transfer barge and the floating pier, meet the technical requirements of rapid deployment, ensure that the transfer barge and the floating pier are safely and reliably connected to each other through the connecting device, and after the connection, it can ensure that the transfer barge and the floating pier remain relatively stable, and the relative movement caused by the action of ocean waves will not cause collision between the multi-module transfer barge and the floating pier.

[0048] By adopting the present invention, no matter how the ocean environment and tidal range change, no matter how the floating pier swings horizontally or rises and falls, the transfer barge and the floating pier can be reliably connected to ensure the safety of the rapid transfer of heavy-loaded equipment and materials.

[0049] The invention has the advantages of simple structure, safety and reliability, low manufacturing cost and great economic value.

[0050] Although the specific embodiments of the present invention are described above, it should be understood by those skilled in the art that this is only for illustration and the protection scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
