Technical Field

[0001] The utility model relates to the technical field of offshore operating platforms, in particular to a steel wire rope locking structure of an offshore operating platform. Background Art

[0002] Offshore self-elevating work platform, especially self-elevating offshore platform, is a mobile offshore platform, usually used for exploration, drilling and oil production in marine engineering. Its structure is mainly composed of platform structure, pile legs and lifting mechanism, and is equipped with living building and other facilities.

[0003] When erecting an existing offshore work platform, it is necessary to lift the platform by a crane to a level 1-2m above the pile body. However, the existing crane wire rope hook lacks a locking structure, resulting in the risk of the platform tipping over and falling when it is lifted. Based on the existing technical deficiencies, the utility model designs a wire rope locking structure for an offshore work platform. Utility Model Content

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. A wire rope locking structure of an offshore work platform, through the locking structure, when the platform is connected to the pile body, the threaded tube is pulled out from the first L-shaped rod by rotating the threaded tube, and then the second L-shaped rod drives the connecting piece to move to the left, and after the plug column passes through the hanging hole, the threaded tube is reset, and the plug column drives the slot column to extend into the installation frame, and the head of the slot column squeezes the blocks on both sides, and the two springs contract and drive the blocks to move to both sides, and when the tips of the two blocks reach the slot of the slot column, the two springs release the force and reset, so that the two blocks can be stuck in the slot column and fixed, and the plug column is locked with the hanging hole at this time, which can prevent the platform from falling during hoisting, and when it is necessary to separate the plug column from the hanging hole, the two sliding columns need to be pulled out from the installation frame, so that the plug column can be separated from the installation frame, thereby separating the plug column from the hanging hole;

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 A wire rope locking structure for an offshore work platform comprises a pile body 1 and a locking structure 5, wherein the locking structure 5 comprises an installation frame 51 and a second L-shaped rod 55, a connecting piece 56 is installed at one end of the bottom of the second L-shaped rod 55, a threaded rod 57 is installed at one end of the connecting piece 56, a plug column 510 is installed at one end of the threaded rod 57, and a groove column 511 is installed at one end of the plug column 510; sliding columns 512 are slidably installed on both sides of the interior of the installation frame 51, a clamping block 513 is installed at the bottom of the two sliding columns 512, a spring 514 is installed on one side of the two clamping blocks 513, one end of the two springs 514 is fixedly connected to the inner wall of the installation frame 51, and a moving wheel 515 is rotatably installed on one side of the two clamping blocks 513, and the two moving wheels 515 are slidably connected to the inner wall of the installation frame 51.

[0022] See also Figure 1-3 A first L-shaped rod 52 is fixedly mounted on the top of the mounting frame 51, and a steel wire rope body 53 is connected to the inside of the first L-shaped rod 52. A threaded tube 54 is rotatably mounted on one side of the second L-shaped rod 55, and one end of the threaded tube 54 is threadedly connected to the first L-shaped rod 52. A threaded sleeve 58 is threadedly mounted on the outer surface of the threaded rod 57, and a plug 59 is rotatably mounted on one side of the threaded sleeve 58.

[0023] When the platform is connected to the pile body, the threaded tube 54 is rotated to be pulled out from the first L-shaped rod 52, and then the second L-shaped rod 55 drives the connecting piece 56 to move leftward, and after the plug post 510 passes through the hanging hole 4, the threaded tube 54 is reset, and the plug post 510 drives the slot column 511 to extend into the installation frame 51. When the locking structure 5 is locked with the hanging hole 4, the threaded sleeve 58 is rotated to move horizontally on the outer surface of the threaded rod 57, so that the threaded sleeve 58 drives the plugging tube 59 to be inserted into the hanging hole 4 and fit closely with it, thereby preventing the locking structure 5 from shaking in the hanging hole 4.

[0024] See also Figure 1-2 A ball pile 2 is installed on the top of the pile body 1, and a hook seat 3 is installed on the top of the ball pile 2. A hanging hole 4 is opened inside the hook seat 3. The hanging hole 4 is plugged with the plug post 510.

[0025] Working principle: when a wire rope locking structure of an offshore work platform is used, in the initial state, first, when the work platform is connected to the pile body, the threaded tube 54 is rotated to pull the threaded tube 54 out of the first L-shaped rod 52, and then the second L-shaped rod 55 drives the connecting piece 56 to move to the left, and after the plug column 510 passes through the hanging hole 4, the threaded tube 54 is reset. At this time, the plug column 510 drives the slot column 511 to extend into the installation frame 51. At this time, the head of the slot column 511 squeezes the blocks 513 on both sides. At this time, the two springs 514 contract and drive the blocks 513 to move to both sides. When the tips of the two blocks 513 reach the slots of the slot column 511, When the locking nut 510 is in the state of being loosened, the two springs 514 release their force and reset, so that the two clamping blocks 513 can be stuck and fixed in the groove column 511. At this time, the plug column 510 is locked with the hanging hole 4 to prevent the platform from falling during lifting. Then, by rotating the threaded sleeve 58 to make it move horizontally on the outer surface of the threaded rod 57, the threaded sleeve 58 can drive the plug pipe 59 to be inserted into the hanging hole 4 and fit tightly with it, thereby preventing the locking structure 5 from shaking in the hanging hole 4. Finally, when it is necessary to separate the plug column 510 from the hanging hole 4, the two sliding columns 512 need to be pulled out from the mounting frame 51 to separate the plug column 510 from the mounting frame 51, thereby separating the plug column 510 from the hanging hole 4.
