The invention provides a wave compensation device used for an offshore floating crane, and belongs to the technical field of offshore floating cranes. The wave compensation device used for the offshore floating crane is provided. The offshore floating crane comprises a ship body, a control room and a crane jib. The wave compensation device comprises a work table. A rotary table is fixed to the ship body. An installation groove is formed in the rotary table. A rotation motor is fixed in the installation groove. A first supporting column and a second supporting column are fixed to the work table. A spline shaft is arranged between the first supporting column and the second supporting column in a rotating manner. A through hole matched with the spline shaft is formed in the crane jib. A heavecompensation mechanism is arranged on the work table and comprises a first lifting cylinder and a second lifting cylinder. A swaying compensation mechanism is arranged on the work table and comprisesa first push cylinder and a second push cylinder. A surging compensation mechanism is further arranged on the work table and comprises a regulation roller. The wave compensation device has the beneficial effect that swaying, surging and heave compensation can be conducted on the crane jib so that it can be ensured that offshore lifted object transfer is more stable, safer and more efficient.
Description
technical field [0001] The invention belongs to the technical field of offshore floating cranes, and relates to an offshore floating crane, in particular to a wave compensation device used for the offshore floating crane. Background technique [0002] Floating cranes are water lifting equipment for fixed-point construction operations in waterways or coastal waters, such as the installation of offshore bridges and bridges, the hoisting of large offshore oil platforms, and the salvage of sunken ships. Floating cranes are divided by the parameter of lifting capacity: small floating cranes with a lifting capacity of less than 1000 tons, medium floating cranes with a lifting capacity of 1000 tons to 2000 tons, large floating cranes with a lifting capacity of 2000 tons to 4000 tons, With a lifting capacity of more than 4,000 tons, it is called a super-large floating crane; with the rapid development of marine engineering heavy equipment technology towards large-scale and high-tech...
