Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings.

[0021] Such as figure 1 , 2 As shown, a multi-degree-of-freedom wind power tower boarding trestle includes a support base 2 and a hydraulic pump station 5 installed on the bow deck 1, and an attitude sensor 3 is installed at the bottom center of the support base 2. The upper end of the machine base 2 is connected to the azimuth turntable 6 through the roll mechanism 4, and the azimuth turntable 6 is connected to the lower ramp 9 through the pitch mechanism 7. An upper ramp 10 is movable in the lower ramp 9, and a wind power tower is installed at one end of the upper ramp 10. The ship berth column 11, the wind power tower is installed on the ship berth column 11 with a wind power tower ladder 12, the bottom of the upper ramp 10 is connected with the bottom of the lower ramp 9 through the telescopic mechanism 8; the roll mechanism 4 includes a ...

Abstract

A multi-degree-of-freedom wind power tower boarding trestle comprises a supporting machine base and a hydraulic pump station which are installed on a bow deck, an attitude sensor is installed in the center of the bottom of the supporting machine base, the upper end of the supporting machine base is connected with an orientation rotary table through a rolling mechanism, the orientation rotary table is connected with a lower accommodation ladder through a pitching mechanism, an upper accommodation ladder is movably installed in the lower accommodation ladder, a wind power tower berthing column is arranged at one end of the upper accommodation ladder, a wind power tower ladder stand is installed on the wind power tower berthing column, and the bottom of the upper accommodation ladder is connected with the bottom of the lower accommodation ladder through a telescopic mechanism. By controlling rolling, pitching, rotation and telescopic movement of the upper accommodation ladder ladder and the lower accommodation ladder ladder, ship body fluctuation caused by sea waves is compensated, and it is ensured that operation and maintenance personnel can safely and rapidly climb the ladder stand of the wind power tower footing; and the trestle has the advantages of being small in size, light in weight, low in cost, safe, stable and convenient to maintain, and potential safety hazards caused when operation and maintenance personnel embark the wind power tower are avoided.

Description

technical field [0001] The invention relates to a multi-degree-of-freedom wind power tower mounting trestle. Background technique [0002] At present, offshore and near-shore wind power towers mainly adopt trestle lap, mechanical hoisting, mechanical lap, bow docking and other methods. [0003] Trestle bridge connection: The large six-degree-of-freedom boarding trestle equipped on the operation and maintenance ship is directly connected to the basic platform of the wind power tower, and the maintenance personnel board the basic platform of the wind power tower through the trestle. [0004] Mechanical lifting: The large-scale mechanical lifting equipment equipped on the operation and maintenance ship directly lifts the maintenance personnel to the foundation platform of the wind power tower. [0005] Mechanical lapping: The operation and maintenance ship is close to the wind power tower foundation, and the ship's mechanical hoop is used to hold the wind power tower foundatio...
