Adjustable platform hoisting ring for wind turbine generator system (WTGS) and WTGS tower

Abstract

The invention provides an adjustable platform hoisting ring for a wind turbine generator system (WTGS). The adjustable platform hoisting ring comprises a hoisting ring plate and a connector part. The connector part is arranged along the circumference of the inner wall of a tower shaft of the WTGS; a plurality of cotter holes are formed along the circumference of the connector part; the hoisting ring plate is provided with a plurality of second cotter holes circumferentially, corresponding to the first cotter holes; the hoisting ring plate is connected with the connector part through bolts running through the first cotter holes and the second cotter holes and end nuts matched with the bolts; the height of the hoisting ring plate in the tower shaft is adjusted by matching between the bolts and the end nuts. The invention further provides a WTGS tower which comprises a control cabinet platform in the middle of the tower shaft of the WTGS and further comprises the adjustable platform hoisting ring used for the WTGS. A platform plate is arranged on the top of the control cabinet platform; the inner side edge of the hoisting ring plate is abutted with the outer side edge of the platform plate through matching between the bolts and the end nuts. The height of the hoisting ring is adjustable; the hoisting plate is convenient to install; the hoisting ring plate is in close contact with the platform plate.

Description

technical field [0001] The invention relates to the technical field of wind turbine towers, in particular to an adjustable platform suspension ring for a wind turbine and a wind turbine tower using the adjustable platform suspension ring. Background technique [0002] The process of installing the wind turbine tower by the on-site personnel of the wind farm is as follows: After positioning and installing the control cabinet platform and the electrical cabinet on the foundation, hoist the bottom section of the tower. Therefore, the size of the platform plate on the control cabinet platform is smaller than the inner diameter of the tower bottom flange, and is also far smaller than the inner diameter of the corresponding position at the bottom of the tower. In accordance with relevant tower design specifications and national standards for construction and fire protection, the gap between the platform slab and the bottom section of the tower should be within the allowable tolera...
