Marine embarkation trestle device with wave compensation function

Abstract

The invention discloses a marine embarkation trestle device with a wave compensation function. Themarine embarkation trestle device comprises a compensation base, an embarkation trestle and a lap joint mechanism, the embarkation trestle is connected with a bow through the compensation base, the embarkation trestle is connected with a pile through the lap joint mechanism, and the lap joint mechanism comprises a fixing part and a hook head part. The fixing part is arranged on the embarkation trestle, the hook head part is hinged to the fixing part, the tail end of the hook head part and the fixing part jointly define a jaw for containing a pile, and the outer arc line, making contact with the pile, of the hook head part is a section of involute so that the pile can be clamped into the jaw from the outer side of the jaw in a clamped mode conveniently. The inner arc line, making contact with the pile, of the hook head part is a section of involute so that the pile in the jaw can be prevented from being disengaged. The structure design is exquisite, lap joint is convenient, the production and manufacturing cost is low, the compensation performance is excellent, and application and popularization are facilitated.

Description

technical field [0001] The invention relates to the technical field of ship engineering equipment, in particular to a ship boarding trestle device with a wave compensation function. Background technique [0002] In offshore operations, it is often necessary to transport personnel and supplies between ships and offshore platforms. Boarding trestles are important supporting equipment connecting ships and offshore platforms. However, the marine environment is harsh, and floating platforms such as ships will roll, Irregular movements such as pitching and heaving will cause boarding trestles to move together, which seriously affects the safety of staff when boarding. When the sea is rough, the staff will not be able to carry out safe and effective operations. Traditional boarding trestles are connected to ships or offshore platforms by overlapping, which has poor adaptability and high safety risks. In the prior art, there are also boarding trestle devices that can perform active...
