Description

Technical Field

[0001] The utility model belongs to the field of unmanned marine platforms, in particular to a floating platform boarding device. Background Art

[0002] Traditional floating platforms are usually equipped with a frame-type berthing structure to facilitate the operation and maintenance vessels to dock sideways or sternways, allowing close boarding. However, since floating platforms are mostly located in deeper waters, under normal sea conditions, there is a possibility of collision between the weak structure of the operation and maintenance vessel and the platform's berthing structure, making docking inconvenient; if the operation and maintenance vessel is separated from the floating platform by a certain distance and does not dock in contact, the boarding personnel need to jump back and forth, and the normal ups and downs of the ship will increase the risk to the boarding personnel.

[0003] If a permanent boarding structure is installed on an already commissioned floating platform, a large cantilever frame will need to be installed. The welding of its ends to the hull structure will affect the cabin structure, making it inconvenient to adjust the cabin pressure relief load during service. In addition, due to the large wave impact force, the strength of the remaining external structures of the hull cannot meet the requirements for the rooting and extension of the cantilever frame. Since the operation and maintenance vessel is not fixed, if a temporary boarding device is installed on it, it needs to be frequently moved, and the arrangement of weights or ground locks and other devices for fixing is relatively cumbersome, and the operating space has certain limitations.

[0004] Therefore, it is urgent to design a floating platform boarding device to solve the above-mentioned problem of floating wind power platform boarding operation. Utility Model Content

[0012] Furthermore, a rubber pad is provided at one end of the vertical circular tube away from the circular handle, and the rubber pad abuts against the external structure of the hull to prevent rigid contact with the external structure of the hull.

[0013] Furthermore, the fixed slot includes an angle steel and a limiting plate, both of which are fixedly arranged on the external structure of the hull, and the angle steel abuts against the vertical circular tube.

The present invention is easy to install, does not require welding to the main hull structure, and does not affect the normal operation of the platform. The boarding ladder frame 2 can be prefabricated as a whole, making it easy to replace. The construction is simple, saving investment, and is applicable to other platform boarding operations with similar restrictions, thus having certain promotional potential.

[0031] Further, if Figure 1 As shown, the boarding ladder frame 2 includes a vertical circular tube 21 and a transverse circular tube 22, and multiple transverse circular tubes 22 are arranged at intervals between two vertical circular tubes 21, and the two vertical circular tubes 21 are arranged in parallel; a safety net 7 is connected between the vertical circular tube 21 and the transverse circular tube 22, and a guardrail 8 is vertically connected to the vertical circular tube 21 to protect the workers; a circular handle 4 is connected to the transverse circular tube 22 connected to the end of the vertical circular tube 21, and a ship hanging ladder 9 is hung on the transverse circular tube 22, so that the workers on the operation and maintenance vessel 10 can climb up to the boarding ladder frame 2 along the ship hanging ladder 9.

[0032] In this embodiment, preferably, two vertical circular tubes 21 are provided, and the two vertical circular tubes 21 are parallel and spaced apart. A plurality of transverse circular tubes 22 are welded between the vertical circular tubes 21, and the plurality of transverse circular tubes 2 are parallel to each other, thereby forming a boarding ladder frame 2. The horizontal and vertical arrangements are utilized to ensure the overall stability and strength of the boarding ladder frame 2. The two ends of the boarding ladder frame 2 are slightly longer to limit the telescopic range as a measure to prevent jumping out.

[0033] A safety net 7 is welded between the vertical circular tube 21 and the horizontal circular tube 22, and guardrails 8 are welded along the length direction on the vertical circular tubes 21 on both sides, thereby protecting the workers and ensuring their safe passage.

[0034] Preferably, a transverse circular tube 22 is also welded to the end of the vertical circular tube 21, and a plurality of circular handles 4 are welded to the side of the transverse circular tube 22 away from the vertical circular tube 21. When personnel need to board the boarding ladder, they connect the circular handle 4 with a rope, pull the circular handle 4, so that the boarding ladder always remains in an extended state, and connect the ship hanging ladder 9 to the end transverse steel tube 22. The operator climbs from the operation and maintenance vessel 10 along the ship hanging ladder 9 to the boarding ladder frame 2.

[0035] When the boarding ladder frame 2 is extended, the marine hanging ladder 9 is hung on the transverse steel pipe 22 at its front end, which plays a role in safe boarding and can limit the movement of the boarding ladder frame 2.

[0036] Further, if Figure 1 and Figure 5 As shown, a roller 11 is provided under the vertical circular tube 21 to enable the boarding ladder frame 2 to be pushed and pulled; a rubber pad 12 is provided at the end of the vertical circular tube 21 away from the circular handle 4, and the rubber pad 12 abuts against the external structure 1 of the hull to prevent rigid contact with the external structure 1 of the hull; the fixed slot 3 includes an angle steel 31 and a limit plate 32, and the angle steel 31 and the limit plate 32 are both fixedly arranged on the external structure 1 of the hull, and the angle steel 31 abuts against the vertical circular tube 21.

[0037] In this embodiment, a plurality of rollers 11 are provided under the vertical circular tube 21. When the circular handle 4 is pulled out, the boarding ladder slides out through the rollers 11, minimizing friction while not being easily stuck, making it easy to push and pull.

[0038] Preferably, a rubber pad 12 is provided below the end of the vertical circular tube 21 away from the circular handle 4, and the rubber pad 12 abuts against the hull external structure 1 to prevent rigid contact with the edge of the platform.

[0043] Preferably, the round steel lock 6 is L-shaped, which is used for personnel on the operation and maintenance vessel 10 to push the lock remotely to unlock or fix the boarding ladder frame 2; the angle steel 31 limits the left and right, up and down movement range of the boarding ladder frame 2, and the limit plate 32 serves as an anti-jumping measure at both ends to limit the forward and backward movement range of the boarding ladder frame 2, and also serves to reinforce the angle steel 31.

[0044] The working principle of the floating platform boarding device in the utility model is as follows:

[0045] The personnel on the operation and maintenance vessel 10 unlock or fix the boarding ladder frame by pushing the lock remotely. The ship hanging ladder 9 is hung on the transverse steel pipe 22 at the end. After the operator climbs up to the boarding ladder frame 2 along the circular handle 4, he enters the external structure 1 of the hull.

[0046] Based on a floating platform boarding device, this utility model utilizes a boarding ladder frame 2 that is slidably mounted on the hull's external structure 1. This prevents the maintenance vessel 10 from docking with the platform, reducing collision risks, increasing the choice of maintenance vessels, expanding its service scope, and reducing the risk of personnel boarding being affected by the vessel's heaving. This device is easy to install, requiring no welding to the main hull structure, and does not affect the normal operation of the platform. The boarding ladder frame can be prefabricated as a whole, making it easy to replace, simple to construct, and economical to invest. It is applicable to other platforms with similar limitations for boarding operations and has considerable potential for promotion.
