Pile driving mechanism for pile sinking at overwater contracted shallow water area

Abstract

The invention relates to a pile driving mechanism for pile sinking at an overwater contracted shallow water area. The pile driving mechanism comprises a hull and a pile frame, wherein the pile frame is hinged to the front end of the hull; the hull is provided with a steady derrick mast behind the pile frame; a first pulley block for reversely rotating the pile frame is connected between the top of the steady derrick mast and the pile frame; a second pulley block for forwardly rotating the pile frame is connected between the hull and the pile frame. According to the pile driving mechanism, the steady derrick mast is additionally arranged on the hull and the first pulley block and the second pulley block are matched for use as a lifting system, so that the forward and reverse rotation of the pile frame are driven, the safety reliability of a pile lifting system can be guaranteed, low-inclination pile sinking construction is met, inclined pile construction of various inclinations are conveniently adapted, the application range of a pile driving boat is expanded, the flexibility for use is improved, and the application range is not limited. The pile driving mechanism can be applied to pile driving construction of the contracted shallow water area.

Description

technical field [0001] The invention relates to a piling ship, in particular to a pile driving mechanism used for pile sinking in narrow and shallow waters above water. Background technique [0002] For piling construction in narrow and shallow waters above the water, due to the narrow construction water area and small construction space, the requirements for piling ships are relatively special. In the prior art, some domestic and foreign standard piling ships meet the technical requirements of pile sinking such as length, inclination, lifting weight, etc., but the hull is too large, and the anchorage space requires a spacious water area, which is easy to collide with the refined oil terminal and the transportation port. The oil trestle bridge affects the normal entry and exit of ships in the channel and harbor basin; some piling ships are small in size, but they cannot be applied because the pile frame and lifting system of the ship machine cannot meet the technical require...

In the prior art, some domestic and foreign standard piling ships meet the technical requirements of pile sinking such as length, inclination, lifting weight, etc., but the hull is too large, and the anchorage space requires a spacious water area, which is easy to collide with the refined oil terminal and the transportation port. The oil trestle bridge affects the normal entry and exit of ships in the channel and harbor basin; some piling ships are small in size, but because the pile frame and lifting system of the ship machine cannot meet the technical requirements of the pile sinking project, they cannot be applied

[0003] In some projects, the design requirements of steel pipe piles are all torsion angles, and there are many changes, and there are several types of slopes, and even slopes as low as 3:1. The piling mechanism on the ship is very difficult to drive, and the safety and reliability of the construction cannot be guaranteed
