Platform cover plate device and wind turbine generator tower and wind turbine generator comprising same

Abstract

The invention discloses a platform cover plate device and a wind turbine generator tower and a wind turbine generator comprising the same and belongs to the field of auxiliary equipment of wind turbine generator sets. The platform cover plate device comprises a translational slide rail system and a platform cover plate capable of sliding on the translational slide rail system, wherein the translational slide rail system comprises two tracks which are arranged on a tower platform and are separately connected to two sides of the platform cover plate; the two tracks are a primary track and a secondary track; a sliding track wheel capable of moving in a slot of the primary track is arranged on the primary track; the sliding track wheel is connected to one side of the platform cover plate for driving the platform cover plate to move; and the other end of the platform cover plate is movably connected to the secondary track. By designing the translational slide rail system, the platform coverplate can translate in the translational slide rail system to open and close, so that the problems that the operating stroke of the platform cover plate of an existing wind turbine generator tower islong, the difficulty of overturning the cover plate by a single arm is great, a connecting hinge is severely damaged as the closing process cannot be controlled and the like are solved.

Description

technical field [0001] The invention relates to the field of auxiliary equipment of a wind power generating set, in particular to a platform cover device, a tower of a wind power generating set and a wind generating set including the same. Background technique [0002] The manhole cover plate of the climbing ladder on the tower platform of the wind turbine is an important part of the accessory parts of the tower platform, and it is also an important metal component frequently opened and closed by the operation and maintenance personnel. , while preventing falling objects from endangering the safety of others or damaging equipment. For the operation and use of the platform climbing ladder cover, usually the safe operation regulations of wind turbines have clear regulations, that is, the tower operator should close it immediately after passing through the tower platform to prevent falling from high altitude. Therefore, the operation and high frequency of use in the climbing p...

AI Technical Summary

Problems solved by technology

[0005] (1) During the closing process of the cover plate, the stroke of the cover plate handle operated by the climber is too long, especially most of the closing process of the left / right side flip plate is uncontrollable;

[0006] (2) The overall quality of the cover plate is relatively large, and it is difficult for operators to turn over the cover plate with one arm.

[0007] (3) In addition, the closing process is out of control and the mass is large, resulting in long-term overload impact on the connecting hinge between the cover plate and the platform, reducing the reliability of the mechanism, and significantly increasing the cost of operation and maintenance and overhaul
