Description

Technical Field

[0001] This utility model relates to the technical field of scaffolding for transshipment operations, specifically a foldable steel structure scaffolding for transshipment operations. Background Technology

[0002] As a crucial link in maritime cargo transshipment and ship replenishment, the gangway is a core channel connecting different vessels or vessels to the dock. Its performance directly affects operational efficiency, safety, and applicability. With the rapid development of the water transport industry, transshipment scenarios are becoming increasingly complex, involving vessels of different tonnages, varying dock conditions, and changes in elevation due to tides. This places higher demands on the adaptability, convenience, and stability of the gangway.

[0003] The existing gangplank length and angle adjustment capabilities are insufficient, making it difficult to cope with different ship spacing, height differences and wharf structure differences. Under scenarios such as tidal changes and ship load adjustments, problems such as unstable connection or insufficient length may occur, affecting the continuity of operations. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a foldable steel structure scaffolding for transshipment operations, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a foldable steel structure plank for transshipment operations, including a first plank, a second plank on the right side of the first plank, an adjustment mechanism inside the first and second planks, a limit mechanism on the outside of the first plank, a connecting rod fixedly connected to the right side of the first plank, and a rotating plate rotatably connected to the periphery of the connecting rod; The adjustment mechanism includes a protective frame, which is fixedly connected to the bottom of the first and second springboards. A threaded rod is rotatably connected to the inner side of the protective frame, and a rotating disk is fixedly connected to the outer side of the threaded rod. A threaded plate is threadedly connected to the outer side of the threaded rod, and a sliding plate is fixedly connected to the top of the threaded plate. A hanging plate is fixedly connected to the bottom outer side of the sliding plate.

[0006] Preferably, there are two connecting rods, which are fixedly connected to the right side of the first springboard and the left side of the second springboard, respectively. The connecting rods can support the rotating plate and allow the rotating plate to rotate around the connecting rods.

[0007] Preferably, the bottom of the first and second springboards is provided with a groove corresponding to the movement trajectory of the threaded plate, and the threaded plate is slidably connected inside the groove. The groove can limit the movement of the threaded plate, making the threaded plate more stable during movement.

[0008] Preferably, the inner sides of the first and second springboards are provided with sliding grooves corresponding to the movement trajectory of the sliding plate, and the sliding plate is slidably connected inside the sliding grooves. Through the sliding grooves, the sliding plate can slide inside the first and second springboards.

[0009] Preferably, the limiting mechanism includes a fixed rod, which is fixedly connected to the outside of the second jump plate. A limiting plate is rotatably connected to the periphery of the fixed rod, and an insert plate is inserted into the periphery of the limiting plate. The insert plate is fixedly connected to the outside of the first jump plate.

[0010] Preferably, there are two fixing rods and insert plates. The two fixing rods are fixedly connected to the front and rear sides of the second jump plate, and the two insert plates are fixedly connected to the front and rear sides of the first jump plate. The fixing rods can support the limiting plate.

[0011] Preferably, the inner side of the insert plate has a slot corresponding to the position of the limiting plate, and the limiting plate is inserted into the slot. Through the slot, the insert plate can be inserted into the slot to limit the first and second springboards, making it difficult for the first and second springboards to rotate.

[0012] Compared with the prior art, this utility model provides a foldable steel structure plank for transshipment operations, which has the following advantages: This foldable steel structure ramp for transshipment operations features an adjustment mechanism that uses a threaded rod to drive a threaded plate, a sliding plate, and a hanging plate in tandem. This allows for precise adjustment of the ramp's support length and overlap position based on actual needs such as ship spacing and dock height during transshipment operations. The sliding plate's design along the sliding groove ensures a stable and smooth adjustment process, effectively compensating for dimensional differences in different operational scenarios and expanding the device's applicability.

[0013] The foldable steel structure gangway used in this transshipment operation has a limiting mechanism in which the limiting plate rotates around the fixed rod and is inserted into the slot of the insertion plate. This can rigidly fix the first gangway and the second gangway after the gangway is unfolded, preventing relative displacement caused by ship swaying and load changes during the operation, and ensuring the overall stability of the gangway structure.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0018] This utility model provides the following technical solution: Example 1

[0019] Please see Figure 1-4 This utility model provides a technical solution: a foldable steel structure scaffolding for transshipment operations, including a first scaffolding 1, a second scaffolding 2 arranged on the right side of the first scaffolding 1, an adjustment mechanism 4 arranged inside the first scaffolding 1 and the second scaffolding 2, a limit mechanism 3 arranged on the outside of the first scaffolding 1, a connecting rod 6 fixedly connected to the inner right side of the first scaffolding 1, and a rotating plate 5 rotatably connected to the periphery of the connecting rod 6. The adjustment mechanism 4 includes a protective frame 43, which is fixedly connected to the bottom of the first springboard 1 and the second springboard 2. A threaded rod 42 is rotatably connected to the inner side of the protective frame 43. A rotating disk 45 is fixedly connected to the outer side of the threaded rod 42. A threaded plate 41 is threadedly connected to the outer periphery of the threaded rod 42. A sliding plate 46 is fixedly connected to the top of the threaded plate 41. A hanging plate 44 is fixedly connected to the bottom outer side of the sliding plate 46.

[0020] Furthermore, there are two connecting rods 6. The two connecting rods 6 are fixedly connected to the right side inside the first springboard 1 and the left side inside the second springboard 2, respectively. The connecting rods 6 can support the rotating plate 5, allowing the rotating plate 5 to rotate around the connecting rods 6.

[0021] Furthermore, the bottom of the first ramp 1 and the second ramp 2 are provided with grooves corresponding to the movement trajectory of the threaded plate 41, and the threaded plate 41 is slidably connected inside the grooves. The grooves can limit the movement of the threaded plate 41, making the threaded plate 41 more stable during movement.

[0022] Furthermore, the inner sides of the first springboard 1 and the second springboard 2 are provided with sliding grooves corresponding to the movement trajectory of the sliding plate 46, and the sliding plate 46 is slidably connected to the inside of the sliding groove. Through the sliding groove, the sliding plate 46 can slide inside the first springboard 1 and the second springboard 2. Example 2

[0023] Please see Figure 1-4 Furthermore, based on Embodiment 1, the limiting mechanism 3 further includes a fixed rod 31, which is fixedly connected to the outside of the second jump plate 2. A limiting plate 32 is rotatably connected to the periphery of the fixed rod 31. An insert plate 33 is inserted into the periphery of the limiting plate 32, and the insert plate 33 is fixedly connected to the outside of the first jump plate 1.

[0024] Furthermore, there are two fixing rods 31 and two insert plates 33. The two fixing rods 31 are fixedly connected to the front and rear sides of the second jump plate 2, and the two insert plates 33 are fixedly connected to the front and rear sides of the first jump plate 1. The fixing rods 31 can support the limiting plate 32.

[0025] Furthermore, the inner side of the insert plate 33 is provided with a slot corresponding to the position of the limiting plate 32, and the limiting plate 32 is inserted into the slot. Through the slot, the insert plate 33 can be inserted into the slot to limit the first jump plate 1 and the second jump plate 2, making it difficult for the first jump plate 1 and the second jump plate 2 to rotate.

[0026] In actual operation, when this device is in use and not in operation, the first plank 1 and the second plank 2 are folded and stored through the hinge structure of the rotating plate 5 and the connecting rod 6. When needed, the operator rotates the first plank 1 and the second plank 2 around the connecting rod 6 so that they are unfolded to the same straight line. The operator then rotates the limiting plate 32 on the outer fixing rod 31 of the second plank 2 so that it rotates around the fixing rod 31 and is inserted into the slot of the outer insert plate 33 of the first plank 1. Through the rigid connection between the limiting plate 32 and the insert plate 33, the first plank 1 and the second plank 2 are locked into an integral structure to prevent relative rotation due to external forces during operation and to ensure the stability of the passage. Based on the distance and height difference between the two vessels during the transshipment operation, the operator rotates the rotating disk 45 inside the protective frame 43, causing the threaded rod 42 to rotate synchronously. Since the threaded plate 41 is threadedly connected to the threaded rod 42, and the threaded plate 41 is limited by the bottom sliding groove, the rotational motion of the threaded rod 42 is converted into the horizontal sliding of the threaded plate 41 along the sliding groove. The sliding plate 46 at the top of the threaded plate 41 moves synchronously with it and slides smoothly along the sliding grooves inside the first jump plate 1 and the second jump plate 2, finally pushing the hanging plate 44 at the bottom of the sliding plate 46 to extend. The hanging plate 44 can be attached to the target vessel or dock. By adjusting the extension length of the hanging plate 44, it can be precisely adapted to different operating distances and improve the reliability of the connection. After adjustment, the first ramp 1 and the second ramp 2 form a stable passageway, which can meet the needs of personnel and goods transfer. After the operation is completed, the rotating disk 45 is rotated in the opposite direction to retract the hanging plate 44, and then the limiting plate 32 is rotated to disengage it from the slot of the insert plate 33, thereby releasing the lock of the first ramp 1 and the second ramp 2. Finally, the first ramp 1 and the second ramp 2 are rotated in the opposite direction around the connecting rod 6 to achieve folding and storage, reduce space occupation, and facilitate transportation and storage.
