Embodiment 1

[0019] Example 1: Combining Figure 1-Figure 4 , a planetary differential lifting device for a wind power installation ship of the present invention, which is composed of three sets of transmission units and a lifting frame, the lifting frame is connected to the transmission unit, and each group of transmission units includes a main transmission assembly (3), an intermediate steering wheel (20) And the auxiliary transmission assembly (4), the main transmission assembly (3) is connected with the rear plate (2) bolts on the lifting frame through the main transmission assembly large flange (128) on it, and through the support ring (114) and the middle plate ( 5) The right side hole is matched, and the matching seal is realized through the O-ring. The tail end shaft of the main transmission assembly (3) is matched with the main bearing (11), the main bearing (11) is matched with the hole of the right front plate (12), and the main bearing (11) Through the axial positioning of the ...

Embodiment 2

[0025] Embodiment 2: The advantages of the present invention are embodied in the following aspects: compact structure and small overall size. Compared with the lifting device with a single output gear structure, the horizontal double output shaft type lifting device designed by the present invention has a compact structure. The installation space is increased; the safety performance of the wind power installation ship is improved. The structure of the planetary differential transmission increases the stability of the operation. At the same time, when the input gear of the lifting device is locked, the two output gears form a self-locking state, and the load is partially offset. Under the action of another gear, it will rotate in the opposite direction to the sinking of the platform, quickly repairing the broken teeth, and improving the safety of the wind power installation ship; the reduction of the overall structure size reduces the amount of manufacturing materials and the q...

Abstract

The invention provides a planet differential lifting device of a wind power installation vessel, consisting of a lifting frame and three groups of transmission units; and each group of transmission units comprises a main transmission component, a medium steering wheel and an auxiliary transmission component. A planet transmission component of the lifting device takes an output solar wheel axle ofa reduction box component as input, and takes a planet frame and a main transmission component main gear of the main transmission component as double-output. The medium steering wheel is synchronously engaged with the main transmission component main gear of the main transmission component and an auxiliary transmission component main gear of the auxiliary transmission component, thus the medium steering wheel belongs to a bridge for transmitting power from the main transmission component to the auxiliary transmission component. Output gears, which have the same size and specification and are completely synchronous, are respectively engaged with racks which are inlaid into pile legs, thus the lifting of the wind power installation vessel can be realized. The invention has the advantages that the size and the weight of the lifting device can be reduced, the operation stability can be increased, and the safety performance of the wind power installation vessel can be improved.

Description

(1) Technical field [0001] The invention relates to mechanical equipment, in particular to a planetary differential lifting device for a wind power installation ship. (2) Background technology [0002] Jack-up wind power installation ship is a special engineering ship, which consists of several parts such as hull, propeller, legs and lifting device. The self-elevating installation ship can not only sail independently, realize the transportation function, but also lift up and down like a self-elevating platform. Through the action of the lifting device, the hull can be lifted a certain distance from the water surface to carry the weight of the hull, providing a stable environment for marine operations. working platform. Due to the characteristics of fast lifting speed and simple operation, the lifting device generally adopts the rack and pinion lifting method. The output gear of the lifting device and the rack on the leg form a rack and pinion structure, and the power is tr...
