when the platform needs to be lifted, the clamping driving piece 341 in the clamping device 34 on the first beam body 31 is shortened, and the clamping block 342 is driven to move in the direction away from the spud leg 2, so that the clamping block 342 is separated from the clamping rack 35; fixture block 342 in the clamping device 34 on the second beam body 32 keeps being connected with the clamping rack 35, and the lifting driving member 33 extends to drive the first beam body 31 to move upwards to a preset distance and then stop, and the clamping driving member 341 in the clamping device 34 on the first beam body 31 extends to drive the fixture block 342 to be close to the spud leg 2, so that the fixture block 342 is matched with the clamping rack 35 again. If the extension amount of the lifting driving member 33 is not an integral multiple of the pitch, in the process of re-matching the fixture block 342 with the clamping rack 35, the adjusting elastic member 346 in the sliding groove 347 compresses or extends to adjust the distance of the fixture block 342 in the lifting direction, so that the fixture block 342 can be smoothly matched with the clamping rack 35 again;
then the limiting part 344 on the clamping device 34 on the second beam 32 is taken down, so that the clamping driving part 341 in the clamping device 34 on the second beam 32 is shortened, the clamping block 342 is driven to move in the direction away from the spud leg 2, the clamping block 342 is separated from the clamping rack 35, the clamping block 342 in the clamping device 34 on the first beam 31 is kept connected with the clamping rack 35, the lifting driving part 33 is shortened, the second beam 32 and the platform 1 are driven to move in the direction close to the first beam 31, that is, the second beam 32 and the platform are driven to ascend together until reaching a preset position and then stop, then the clamping driving part 341 in the clamping device 34 of the second beam 32 is extended, the clamping block 342 is driven to be close to the spud leg 2, and the clamping block 342 is matched with the clamping rack 35 again.
The actuating process of making the platform descend is opposite to the above-mentioned process, namely make clamping device 34 on the first roof beam body 31 keep the joint with joint rack 35 earlier, and the extension of lift driving piece 33 promotes second roof beam body 32 and platform 1 whereabouts, then clamping device 34 on the second roof beam body 32 links to each other with joint rack 35, and it can to shorten the first roof beam body 31 whereabouts of drive of lift driving piece 33.
When the lifting operation is not required, the limiting member 344 having a wedge-shaped structure is inserted into the limiting hole 345, so that the side surface of the limiting member 344 abuts against one side of the fixture block 342, which is far away from the clamping rack 35, thereby limiting the position of the fixture block 342, and preventing the fixture block 342 and the clamping rack 35 from being in failure due to failure of the lifting driving member 33.
The embodiment of the utility model provides a lifting device 3's beneficial effect lies in:
compared with the bolt type ocean platform in the prior art, the lifting device 3 provided by the utility model realizes the sliding and fixing between the platform 1 and the pile leg 2 through the matching and separation of the clamping rack 35 and the clamping block 342, the processing technology of the clamping rack 35 is mature, for example, the high-efficiency processing of the clamping rack 35 can be realized by adopting linear cutting, the precision is easy to ensure, thereby avoiding the situation that the clamping block 342 and the clamping rack 35 can not be aligned normally; meanwhile, because the teeth on the rack are closely arranged, even if the sea bed surface is uneven, the fixture block 342 can be matched and connected with the clamping rack 35 at a proper position, so that one or more hydraulic stations and the hydraulic cylinder are prevented from being in a working state for a long time, and the production safety is improved.
