Description

Technical Field

[0001] This utility model belongs to the field of offshore oil and gas production technology, specifically relating to a material transfer device for offshore platform scaffolding. Background Technology

[0002] Offshore oil and gas production facilities are large steel engineering structures. Offshore platforms typically consist of multiple decks, each housing various equipment. Due to the large size of the equipment and the need to meet functional requirements and platform safety standards, the height between decks is considerable, resulting in many operations involving working at height. The offshore environment is often characterized by strong winds, and many mobile aerial work platforms usable on land cannot be used on offshore platforms. Therefore, the maintenance and repair of much equipment and the upkeep of the platform structure on offshore platforms often involve scaffolding erection.

[0003] The annual workload for scaffolding erection on offshore platforms is substantial, involving equipment skids, overhead pipelines, overboard operations, tanks, and more, resulting in the use of large quantities of scaffolding materials. However, the lack of dedicated scaffolding material transfer equipment at work sites leads to numerous problems, as detailed below: 1. There are many scaffolding materials, and in many places the platform crane cannot lift them. At the same time, it involves working at different heights, which means that the materials can only be moved manually little by little, resulting in low transportation efficiency.

[0004] 2. When personnel are moving scaffolding materials at different heights, there are no special tools available. Some scaffolding tubes are long and heavy, posing a risk of bumping into other equipment and personnel during the transfer. In addition, due to manual handling and the long length of the scaffolding tubes, it is very inconvenient to go up and down stairs.

[0005] 3. During the erection of scaffolding, the scaffolding pipes need to be manually pulled to the corresponding height one by one using ropes. On the one hand, this requires a high level of physical strength from the workers, and on the other hand, there is a risk of the scaffolding pipes falling. Once the scaffolding pipes fall, it may cause serious personal injury.

[0006] 4. During the handling of scaffolding materials, some materials are heavy and may damage the painted surface of the platform if personnel are not careful, increasing the difficulty of on-site anti-corrosion management. Summary of the Invention

[0007] The purpose of this utility model is to provide a material transfer device for offshore platform scaffolding, which facilitates the transfer of scaffolding, reduces the labor intensity of workers, ensures safe and reliable operation, and reduces safety accidents during the transfer of scaffolding materials.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] like Figure 1-4 As shown, this utility model discloses a material transfer device for offshore platform scaffolding, including a slide rail structure 100, a bottom support seat 200, a top support seat 300, and a lifting assist structure 400 connected to the top support seat.

[0023] Preferably, the bottom support 200 and the top support 300 have the same structure, each including two columns 1, a crossbar 2, a rotating column 3, a support block 4, and a buffer pad 5. The tops of the two columns 1 are connected by the crossbar 2. The bottom end of each column 1 is connected to the support block 4. By setting the support block 4, the force-bearing area is increased, and the stability of the transfer device is improved. The rotating column 3 is installed in the middle of the two columns 1. The buffer pad 5 is set on the bottom surface of the support block. By setting the buffer pad 5, damage to the paint on the deck surface can be effectively avoided.

[0024] The slide rail structure 100 includes a slide rail groove 101, a groove cover 102, a spring 103, a spring fixing block 104, and a buffer block 105. The upper end of the slide rail groove 101 is connected to the rotating column of the top support 300 via an upper fixing block 106 and is fixed with bolts; the lower end of the slide rail groove 101 is connected to the rotating column of the bottom support 200 via a lower fixing block 107 and is fixed with bolts. After connection, the end of the slide rail groove 101 can rotate relative to the corresponding support, adapting to installations at different heights. The spring fixing block 104 is welded to the lower end of the slide rail groove 101, and both ends of the spring 103 are fixedly connected to the spring fixing block 104 and the buffer block 105, respectively. The long side of the groove cover 102 is connected to the slide rail groove via a hinge, allowing it to be flipped open or closed.

[0025] The lifting assist structure 400 includes a connecting seat 401, a rope drum 402, a rotating shaft 403, and a driving component 404 for rotating the rotating shaft. The connecting seat 401 is fixedly connected to the top support 300. The rope drum 402 is mounted on the connecting seat 401 via the rotating shaft 403. The driving component 404 can rotate the rope drum 402. The driving component 404 is a hand crank connected to one end of the rotating shaft. Of course, if the site conditions are suitable, an electric drive mechanism, such as a motor drive, can also be used.

[0026] In use, the transfer device of this utility model shall be installed according to the actual situation. The top support 300 shall be installed at a high position where the material needs to be transferred, the bottom support 200 shall be installed at a low position where the material needs to be transferred, and the slide rail structure shall be installed on the bottom support 200 and the top support 300.

[0027] When scaffolding materials need to be transferred from a high place to a low place, the scaffolding materials are placed into the slide rail groove 101 from the high place, the groove cover 102 is closed, and after the scaffolding materials are released, the scaffolding materials slide down under the action of gravity until they come into contact with the buffer block 105 for energy buffering. After the scaffolding materials come to a stop, the groove cover 102 is opened and the scaffolding materials are taken out.

[0028] When scaffolding materials need to be transferred from a lower to a higher position, place the scaffolding materials into the slide rail groove 101, release the pull rope wrapped around the rope drum 402, and use the pull rope to fix the scaffolding materials. Cover the groove 102, use the hand crank to turn the rope drum 402, and pull the scaffolding materials up along the slide rail groove. After reaching the designated height, open the groove 102 and take out the scaffolding materials.

[0029] When the transfer device is not in use, the slide rail structure can be removed from the bottom support 200 and the top support 300 and stored in three parts. When the device needs to be used, it can be reconnected with bolts.

[0030] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
