Crane pile lifting system under condition of barging piles at sea and construction method

Abstract

The invention relates to a crane pile lifting system under the condition of barging piles at sea. The system comprises a crane, a shifting device mounted on a deck for moving a steel pipe pile to be lifted to a pile lifting position, a rail paved in the pile lifting position, a pile delivery trolley arranged on the rail, a traction device connected to the pile delivery trolley, and a sleeper arranged below the rail. According to the crane pile lifting system disclosed by the invention which is assisted by adoption of such devices as the pile delivery trolley under the condition of barging the piles at the sea, as the rail and the pile delivery trolley are arranged, the tail end of the pileisput on the trolleyduring lifting, the trolleymoves on the rail in the lifting process, the tail end of the piledoes not directly rub the deck, and the pressure of the steel pipe pile on the deck acts on the rail to increase the stressed area so as to cause collapse of the deck; and in the lifting process, the condition of transverse displacement of the pile is prevented due to limit by the rail.

Description

technical field [0001] The invention relates to a system and a method for lifting piles by a crane under the condition of pile storage above sea. Background technique [0002] At present, domestic offshore piles mainly use land hoisting technology. During the pile lifting process, the tail end of the pile directly contacts the deck. This technology has two main disadvantages: 1. The pile directly contacts the deck, which will cause deck wear. If the deck is loaded If it is not enough, it will also cause the deck to collapse; 2. During the lifting process, there will be uncontrollable lateral displacement of the pile, which will increase the risk factor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a crane hoisting pile under the condition of pile barging above the sea, and a construction method, so that the tail end is not directly connected to the deck during the pile hoisting process, and the deck is protect...
