Description

Technical Field

[0001] The utility model relates to the technical field of marine engineering, in particular to a marine loading and unloading system for a ship unloader. Background Art

[0002] Ship unloaders are usually transported by barge to the user's wharf for delivery. However, most of the wharves where ship unloaders are installed are trestle-type wharves (i.e., both the sea and land sides are adjacent to the water), and the wharfs are also equipped with surrounding buildings such as corridors or operating facilities such as belt conveyors, leaving little space for the unloader to unload the ship.

[0003] The current roll-on / roll-off unloading process usually adopts the method of horizontal berthing and unloading. When the ship unloader is on the barge, its length direction is parallel to the length direction of the barge. When unloading, the side of the barge is berthed in the middle of the dock shoreline, and the ship unloader goes ashore from the middle of the dock. The travel mechanism of the ship unloader will interfere with the corridor bridge, belt conveyor and other facilities on the dock. At this time, buildings such as corridors or operating facilities such as belt conveyors must be demolished, and the entire production line of the dock needs to stop operating, interrupting the production rhythm of the dock. Utility Model Content

[0004] In view of this, the utility model provides a ship unloader marine loading and unloading system, which does not require the removal of dock facilities and can effectively improve the dock production efficiency.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] The embodiment of the utility model provides a ship unloader marine loading and unloading system, including: a loading dock, a barge, a berthing dock and a traction mechanism. Among them, a first roll-on / roll-off track is arranged on the loading dock, and the first roll-on / roll-off track is arranged along the first direction, used to carry the ship unloader, and the length direction of the ship unloader is parallel to the first direction; the barge includes a hull, a second roll-on / roll-off track and a third roll-on / roll-off track. Among them, the second roll-on / roll-off track is arranged on the hull and arranged along the first direction, used to dock with the first roll-on / roll-off track and carry the ship unloader, and the first direction is a direction parallel to the side of the barge; the third roll-on / roll-off track is arranged along the second direction and intersects with the second roll-on / roll-off track, and the second direction is perpendicular to the first direction; a fourth roll-on / roll-off track extending along the second direction is arranged on the berthing dock, and the fourth roll-on / roll-off track is used to dock with the third roll-on / roll-off track and carry the ship unloader; the traction mechanism is arranged on the berthing dock, and is used to tow the ship unloader from the third roll-on / roll-off track to the fourth roll-on / roll-off track.

[0040] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0041] In order to facilitate the understanding of the technical solution of the present utility model, the technical problem to be solved by the present utility model is first described.

[0042] Ship unloaders are usually transported by barges for ocean shipping, and the whole machine is transported to the user's wharf for delivery. However, the trestle-type wharf is also equipped with surrounding buildings such as corridors or operating facilities such as conveyors, and the space reserved for the whole ship unloader to unload the ship is small. When the barge is unloaded by berthing horizontally, the side of the barge is moored in the middle of the wharf shoreline, and the ship unloader goes ashore from the middle of the wharf. At this time, wharf facilities such as corridors or conveyors must be removed, and the entire production line of the wharf must stop operating, interrupting the production rhythm of the wharf. In addition, for some wharves with special construction forms, such as short shoreline wharves that cannot provide the long mooring cables and operating intervals required for ship-side berthing and unloading, low-water-depth wharves with insufficient water depth in the front water area for roll-on / roll-off unloading, and narrow channel wharves with difficulty in anchoring and entering and leaving the port, it is impossible to use the ship-side berthing and unloading method for unloading. At this time, floating cranes can only be used for unloading, which adds a lot of workload and cost to the unloading work.

[0043] In order to solve the above technical problems, the utility model provides a marine loading and unloading system of a ship unloader.

[0044] Firstly, a ship unloader marine loading and unloading system according to an embodiment of the utility model will be described in detail below with reference to the accompanying drawings.

[0045] refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the ship unloader during loading in the ship unloader marine loading and unloading system in some embodiments of the utility model. Figure 2 It is a top view of a ship unloader unloading a ship in a marine loading and unloading system of a ship unloader in some embodiments of the utility model.

[0046] like Figure 1 and Figure 2 As shown, the marine loading and unloading system of the ship unloader 101 of the embodiment of the utility model comprises: a loading dock 100, a barge, a berthing dock 300 and a traction mechanism 400. Among them, a first roll-on / roll-off track 110 is arranged on the loading dock 100, and the first roll-on / roll-off track 110 is arranged along a first direction for carrying the ship unloader 101, and the length direction of the ship unloader 101 is parallel to the first direction. The barge comprises a hull 210, a second roll-on / roll-off track 220 and a third roll-on / roll-off track 230. Among them, the second roll-on / roll-off track 220 is arranged on the hull 210 and arranged along a first direction for docking with the first roll-on / roll-off track 110 and carrying the ship unloader 101, and the first direction is a direction parallel to the side of the barge. The third roll-on / roll-off track 230 is arranged along a second direction and intersects with the second roll-on / roll-off track 220, and the second direction is perpendicular to the first direction. The berthing terminal 300 is provided with a fourth roll-on / roll-off track 310 extending in the second direction, and the fourth roll-on / roll-off track 310 is used to dock with the third roll-on / roll-off track 230 and carry the ship unloader 101. The traction mechanism 400 is provided on the berthing terminal 300, and is used to tow the ship unloader 101 from the third roll-on / roll-off track 230 to the fourth roll-on / roll-off track 310.

[0047] In this embodiment, the first direction is a direction parallel to the side of the barge. Figure 3 and Figure 4 , Figure 3 This is a front view of the ship unloader after loading in the ship unloader marine loading and unloading system in some embodiments of the utility model. Figure 4 This is a side view of the ship unloader after loading in the ship unloader marine loading and unloading system in some embodiments of the utility model. Figure 3 and Figure 4 As shown, the ship unloader 101 includes an equipment body and two groups of trolley travel mechanisms symmetrically arranged below the body. The space between the two groups of trolley travel mechanisms 102 forms the mid-span of the ship unloader 101. After the ship unloader 101 is loaded into the barge, the beam of the ship unloader 101 is perpendicular to the length direction of the barge, so that multiple ship unloaders 101 can be loaded along the length direction of the barge. The mid-span of the ship unloader 101 is directly opposite to the bow of the barge, so that when the bow of the barge docks with the berthing dock 300 during unloading, the dock facilities 600 pass through the mid-span of the ship unloader 101.

[0048] Further, refer to Figure 2 Combined with Figure 5 , Figure 5 This is a side view of a ship unloader in a ship unloader marine loading and unloading system in some embodiments of the present invention when unloading a ship. Figure 2 and Figure 5As shown, during unloading, the tugboat 240 can assist the barge in moving so that the bow of the barge can be against the berthing terminal 300. At this time, the ship unloader 101 can be towed by the towing mechanism 400, and the ship unloader 101 can be towed along the third roll-on / roll-off track 230 perpendicular to the second roll-on / roll-off track 220 to the fourth roll-on / roll-off track 310, and the towing is continued so that the terminal facility 600 passes through the span of the ship unloader 101. Therefore, there is no need to dismantle the facilities on the berthing terminal 300, which reduces the dismantling and restoration work and improves the work efficiency of the terminal.

[0049] In addition, if Figure 1 As shown, by arranging a plurality of first roll-on / roll-off tracks 110 extending along a first direction on the barge, the barge can be loaded with a plurality of ship unloaders 101, thereby improving the loading efficiency.

[0050] refer to Figure 2 , and combined with Figure 6 , Figure 6 This is a schematic diagram of the structure of the cushion in the marine loading and unloading system of the ship unloader in some embodiments of the utility model. Figure 2 and Figure 6 A cushion 320 is provided on the breast wall at the end of the berthing pier 300. By providing the cushion 320 on the breast wall, a buffer can be provided when the bow of the barge abuts against the breast wall of the berthing pier 300, thereby avoiding collision between the barge and the berthing pier 300.

[0051] Further, refer to Figure 7 and Figure 8 , Figure 7 This is a schematic structural diagram of the cushion P direction in the marine loading and unloading system of the ship unloader in some embodiments of the utility model. Figure 8 This is a schematic diagram of the structure of the cushion MM direction in the ship unloader marine loading and unloading system in some embodiments of the utility model. Figure 7 and Figure 8 As shown, a soft buffer layer is provided on the side of the cushion 320 facing the barge. In some other embodiments of the utility model, the cushion 320 may be a plurality of interconnected soft buffer layers. By providing soft buffer layers on the breast wall side of the cushion 320 facing the berthing pier 300 and the side facing the barge, effective buffering can be performed to prevent damage to the barge or the berthing pier 300.

[0052] As shown in Figure 6, the length of the cushion 320 is greater than the length of the breast wall, and the bottom of the cushion 320 is connected to the seabed filler sleeper. Thus, the breast wall of the wharf can be fully protected and prevented from being damaged.

[0053] like Figure 2 and Figure 5As shown, the traction mechanism 400 includes: a plurality of traction anchors 410 and a pulley traction device (not shown). The traction anchor 410 is set on the berthing terminal 300 and is used to position the steel wire rope 414 connected to the ship unloader 101. The pulley traction device is connected to the steel wire rope 414 and is used to pull the ship unloader 101 so that the facilities on the berthing terminal 300 pass through the span of the ship unloader 101.

[0054] In this embodiment, the traction anchor 410 is a temporary chemical anchor. By using the temporary traction anchor 410, on the one hand, the steel wire rope 414 can be positioned when the pulley traction device is traction, thereby improving the stability during traction. On the other hand, the temporary traction anchor 410 can be removed after the ship is unloaded, thereby avoiding affecting the layout of the dock.

[0055] refer to Figure 9-11 , Fig. 9 It is a side view of a traction anchor in a marine loading and unloading system of a ship unloader in some embodiments of the utility model. Fig.10 This is a front view of a traction anchor in a marine loading and unloading system of a ship unloader in some embodiments of the utility model. Fig.11 The top view of the traction anchor in the marine loading and unloading system of the ship unloader in some embodiments of the utility model. The traction anchor 410 includes: a fixing plate 411, a lug plate 412 and a plurality of groups of reinforcing rib plates 413. The fixing plate 411 is arranged in a pre-buried pit on the berthing wharf 300. The lug plate 412 is perpendicular to the fixing plate 411 and connected to the fixing plate 411, and a through hole for a steel wire rope 414 is arranged on the lug plate 412. The plurality of groups of reinforcing rib plates 413 are respectively connected to the fixing plate 411 and the lug plate 412.

[0056] In this embodiment, the ear plate 412 is provided on the fixing plate 411 in the pre-buried pit, and the steel wire rope 414 is passed through the steel wire rope 414 through hole on the ear plate 412 for positioning, thereby improving the stability during traction. In addition, by providing multiple groups of reinforcing rib plates 413 to respectively connect the ear plate 412 and the fixing plate 411, the structural strength of the traction anchor 410 is effectively improved.

[0057] like Figure 2 As shown, the ship unloader 101 marine loading and unloading system further includes: a plurality of mooring anchors 500. The mooring anchors 500 are arranged on the berthing pier 300 and are used for mooring barges.

[0058] In this embodiment, the mooring anchor 500 is a temporary chemical anchor. By using the temporary mooring anchor 500, it can be removed after the ship is unloaded, thus avoiding affecting the layout of the dock.

[0059] In one embodiment of the utility model, the barge is provided with a plurality of fixing frames (not shown) for fixing the ship unloader 101. The fixing frames can be used to limit the position of the ship unloader 101 during transportation to prevent the ship unloader 101 from moving, thereby effectively improving safety.

[0060] In summary, the ship unloader marine loading and unloading system of the embodiment of the utility model, by transporting the ship unloader to the barge along the first direction, makes the mid-span of the ship unloader perpendicular to the length direction of the barge, so that the barge can carry multiple ship unloaders, thereby improving the transportation efficiency. When unloading, by abutting the bow of the barge with the berthing dock, the ship unloader can be moved along the second direction to the fourth roll-on / roll-off track on the dock, and the facilities on the berthing dock can pass through the mid-span of the ship unloader, so there is no need to dismantle the facilities on the berthing dock, reducing the dismantling and restoration work, and improving the work efficiency of the dock. In addition, since the dock generally abuts the side of the ship against the dock when mooring the ship, the mooring piles on the dock are also fixedly set, and the barge of the utility model abuts the dock with the bow, by setting a removable mooring anchor and a traction anchor on the berthing dock, it can be dismantled after the unloading is completed, thereby avoiding affecting the layout of the dock.
