Description

Technical Field

[0001] This utility model relates to the technical field of key facilities for marine transshipment operations, specifically to a scaffolding device that also serves as a bow gate. Background Technology

[0002] As an important supporting device for transport ships, gangplanks are widely used in ship operations, with their core application concentrated in ro-ro operations at docks. The conventional operating mode of existing gangplanks is: during operation, they are deployed and overlapped on the dock, shore, or other fixed structures, which can only achieve the single function of "active overlap" and does not have the "passive overlap" capability of being overlapped by other structures.

[0003] This structural design flaw severely limits the application scenarios of existing gangplanks, making them unsuitable for transshipment operations at sea far from ports. When transport ships need to transfer cargo with other vessels in the open ocean without fixed docks, the lack of gangplank devices makes it difficult to carry out transshipment operations smoothly.

[0004] To address the aforementioned technical challenges and meet the practical needs of offshore transshipment operations, there is an urgent need to develop a new type of gangway device with transshipment functionality. Utility Model Content

[0005] In view of this, the present invention provides a scaffolding device that can also be used as a bow gate, which can effectively withstand scaffolding loads and passage loads, thereby enabling scaffolding and transshipment operations in a marine environment.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A bridge-mounted device that also serves as a bow gate includes a bow bridge structure, a tie rod, a sealing device frame, a bridge, a ship-connecting hinge, a winch mechanism, a fastening device, and a locking device.

[0008] One end of the bow ramp structure is connected to the hull via a ship-connecting hinge to form a hinged end; the other end of the bow ramp structure is connected to the hull via a diagonal tie rod in the deployed state, and the diagonal tie rod is used to support the cantilever end of the bow ramp structure.

[0009] The winch mechanism is mounted on the hull and is used to pull the bow ramp structure to rotate around the ship's connecting hinge, thereby enabling the bow ramp structure to be deployed and retracted.

[0010] One end of the ramp is hinged to the hull, and the other end is attached to the bow ramp structure to overcome the gap between the hull and the bow ramp structure.

[0011] The sealing device frame is fixed to the end face of the hull. When the bow ramp structure is in the locked state, the bow ramp structure is fixed to the hull by the locking device and fastening device and used as a bow door. The bow ramp structure is pressed onto the sealing device frame to achieve sealing.

[0012] Furthermore, the two sets of winch mechanisms are symmetrically arranged on both sides of the ship's deck, and each set of winch mechanisms includes a winch, a wire rope, and a fixed pulley;

[0013] The winch is fixed to the hull, one end of the wire rope is connected to the winch, the wire rope passes around the fixed pulley to achieve the wire rope turning, and the other end of the wire rope is fixedly connected to the side of the bow ramp structure; the connection point of the wire rope on the bow ramp structure is located outside the connection point of the tie rod on the bow ramp structure.

[0014] The winch drives the wire rope to pull the bow ramp structure to rotate around the ship's hinge, thereby enabling the bow ramp structure to be deployed and retracted.

[0015] Furthermore, each hoisting mechanism includes two fixed pulleys, with the outer fixed pulley being higher than the inner fixed pulley.

[0016] Furthermore, the locking device is located on the deck surface above the hull, and the fastening device is located on both sides of the hull.

[0017] Furthermore, the tie rod is a two-fold type, with double ears at both ends, and a single-ear connector is correspondingly provided at the connection points of the hull and the bow ramp that are hinged to the tie rod.

[0018] Furthermore, a protective plate is provided on the inner side of the tie rod, and the height of the protective plate corresponding to the connection between the tie rod and the bow ramp is not less than the height of the single-ear joint.

[0019] Beneficial effects:

[0020] 1. This utility model uses diagonal braces to support the bow ramp structure. The diagonal braces are the main load-bearing components during the loading process of the ramp device. The force generated by the overlapping load and the passing load acting on the bow ramp structure is transmitted to the diagonal braces through the hinge point between the bow ramp structure and the diagonal braces. Then, the force is transmitted to the hull through the hinge point between the diagonal braces and the hull. This ensures that the strength of the bow ramp structure meets the design requirements, and its front end has the function of being overlapped when it is in a cantilever state. When used as the bow door of the bow ramp structure, it also meets the function of weather sealing.

[0021] 2. The connection point of the wire rope on the bow ramp structure of this utility model is located outside the connection point of the tie rod on the bow ramp structure, so as to avoid interference when the bow ramp structure is retracted.

[0022] 3. The inner side of the tie rod of this utility model is equipped with a protective plate to avoid collision damage to the tie rod caused by the load or the traffic load. Attached Figure Description

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] This utility model provides a spliced ​​ramp device that also functions as a bow gate, such as... Figure 1 As shown, it includes a bow ramp structure 1, a tie rod 2, a sealing device frame 3, a ramp 4, a ship-connecting hinge 5, a winch mechanism, a fastening device 6, and a locking device 10.

[0031] One end of the bow ramp structure 1 is connected to the hull 11 via a ship-connecting hinge 5, forming a hinged end. The other end of the bow ramp structure 1, in its deployed state, is connected to the hull 11 via a tie rod 2. One end of the tie rod 2 is hinged to the hull 11, and the other end is hinged to the surface of the bow ramp structure 1, serving to support the cantilever end of the bow ramp structure 1. The tie rod 2 is a primary load-bearing component in the loading process of the lap ramp device, which also functions as a bow door. The force generated by the lap load and the passage load acting on the bow ramp structure 1 is transmitted to the tie rod 2 through the hinge point between the bow ramp structure 1 and the tie rod 2, and then further transmitted to the hull 11 through the hinge point between the tie rod 2 and the hull 11.

[0032] The winch mechanism is installed on the hull 11 and is used to pull the bow ramp structure 1 to rotate around the ship-connecting hinge 5, so as to realize the deployment and retraction of the bow ramp structure 1.

[0033] One end of the ramp 4 is hinged to the hull 11, and the other end is attached to the bow ramp structure 1. When the bow ramp structure 1 is deployed, the plane of the ramp 4 connects with the plane of the bow ramp structure 1 to overcome the gap between the hull 11 and the bow ramp structure 1. When the winch 7 drives the wire rope 8 to pull the bow ramp structure 1 to rotate around the connecting hinge 5, the ramp 4 moves accordingly.

[0034] The sealing device frame 3 is fixed to the end face of the hull 11. When the bow ramp structure 1 is in the locked state, the sealing device frame 3 works with the bow ramp structure 1 to realize the bow door function.

[0035] Both the locking device 10 and the fastening device 6 are fixed to the hull 11. When the bow ramp structure 1 is in the locked state, the locking device 10 and the fastening device 6 fix the bow ramp structure 1 to the hull 11, serving as a bow door. The locking device 10 and the fastening device 6 press the bow ramp structure 1 onto the sealing device frame 3 to achieve a weatherproof function. The mating surface between the hull 11 and the bow ramp structure 1 is an inclined surface, which slopes from the upper outer side to the lower inner side.

[0036] Specifically, such as Figure 5 As shown, the locking device 10 is installed on the deck surface above the hull 11, and the fastening device 6 is installed on both sides of the hull 11. The number of locking devices 10 and fastening devices 6 is selected according to the actual situation and evenly distributed. In this embodiment, three locking devices 10 are arranged at intervals, and two fastening devices 6 are arranged at intervals on each side.

[0037] The locking device 10 can be a combination of a hook and a pin. The hook is fixed to the deck surface, and the pin is correspondingly set on the surface of the bow ramp structure 1. The hook head is engaged with the pin to achieve locking.

[0038] The fastening device 6 can be a combination of a pin and a pin hole. The pin is located on the side of the hull 11, and the pin hole is machined on the side of the bow ramp structure 1.

[0039] In this embodiment, two sets of winch mechanisms are symmetrically arranged on both sides of the deck 11 of the ship. Each set of winch mechanisms includes a winch 7, a wire rope 8, and a fixed pulley 9.

[0040] The winch 7 is fixed to the hull 11. One end of the wire rope 8 is connected to the winch 7. The wire rope 8 passes around the fixed pulley 9 to achieve the turning of the wire rope 8. The other end of the wire rope 8 is fixedly connected to the side of the bow ramp structure 1. The connection point of the wire rope 8 on the bow ramp structure 1 is located outside the connection point of the tie rod 2 on the bow ramp structure 1, that is, the connection point of the wire rope 8 on the bow ramp structure 1 is further away from the ship-connecting hinge 5.

[0041] The winch 7 drives the wire rope 8 to pull the bow ramp structure 1 to rotate around the ship-connecting hinge 5, thereby realizing the deployment and retraction of the bow ramp structure 1.

[0042] Each hoisting mechanism includes two fixed pulleys 9, with the outer fixed pulley 9 being higher than the inner fixed pulley 9. If only one fixed pulley 9 is used, the winch 7 needs to be raised. Compared to this solution, the combination of high and low fixed pulleys is simpler to set up and the pulling process is more effortless and stable.

[0043] The tie rod 2 is a double-fold type, with double lugs at both ends. A single-lug connector is correspondingly provided at the connection points between the tie rod 2 and the hull 11 and the bow ramp. The folding point position of the tie rod 2 and the length ratio of the two sections are adjusted according to the recovery status.

[0044] As an improvement, a protective plate is provided on the inner side of the tie rod 2. The height of the protective plate corresponding to the connection between the tie rod 2 and the bow ramp is not less than the height of the single-ear joint. The height of the protective plates on other parts of the tie rod 2 can be lower than the height of the single-ear joint, or it can be the same as the height of the protective plate corresponding to the connection with the bow ramp.

[0045] like Figure 2 The diagram shows the unfolding process of the overlapping plank device used as a bow gate in this utility model. This unfolding process begins from the locked state (as shown in the diagram). Figure 4 As shown) to the unfolded state (such as Figure 1 As shown, during the transformation process, the deployment action begins. The locking device 10 and fastening device 6 release their constraints on the bow ramp structure 1, and the winch 7 releases the wire rope 8, allowing the bow ramp structure 1 to rotate around the connecting hinge 5 under its own weight. When the bow ramp structure 1 is deployed and lowered to the designated position, the diagonal tie rod 2 is tensioned and under force, and the bow ramp structure 1 is in a suspended state. At this time, the deployment action is completed, and the ramp device, which also serves as a bow door, is in the deployed state and has the function of being connected for loading.

[0046] like Figure 3 The diagram shows the retraction process of the overlapping ramp device, which also functions as a bow gate, according to this utility model. This retraction process begins from the deployed state (e.g., ...). Figure 1 As shown) to the locked state (e.g.) Figure 4 As shown, during the transformation process, the retraction action begins. The winch 7 pulls the steel wire rope 8 to rotate the bow ramp structure 1 around the ship-connecting hinge 5, retracting it until the bow ramp structure 1 is in contact with the sealing device door frame 3. The locking device 10 tightens the bow ramp structure 1, and then the fastening device 6 fastens the bow ramp structure 1 to the sealing device door frame 3. At this time, the retraction action is completed, and the ramp device that also serves as the bow door is in a locked state and can be used as the bow door, thus meeting the conditions for sailing with the ship.

[0047] In summary, the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
