Abstract

The invention provides a pull-rope-type wind turbine generator engine cabin object-craning hole lid. The pull-rope-type wind turbine generator engine cabin object-craning hole lid comprises a push-pull lid, a flexible rope and a guiding part, the push-pull lid is slidably connected to an object-craning hole, the end, close to the object-craning hole, of the guiding part is annularly arranged fromthe inner side of an engine cabin to the other end close to the object-craning hole, the flexible rope is arranged along the guiding part, the two ends of the flexible rope are both connected with thepush-pull lid, and by pulling the flexible rope, the push-pull lid is driven to slide to open or close the object-craning hole. The pull-rope-type wind turbine generator engine cabin object-craning hole lid is simple in structure and low in cost, maintenance personnel who use the pull-rope-type wind turbine generator engine cabin object-craning hole lid can conveniently and quickly open or closethe wind turbine generator engine cabin object-craning hole simply by standing on a rack pedal to pull the flexible rope without climbing to the bottom of the engine cabin, and the pull-rope-type windturbine generator engine cabin object-craning hole lid is convenient to use, safe and reliable.

Description

technical field [0001] The invention relates to the technical field of wind turbines, in particular to a cable-type wind turbine nacelle hanger hole cover. Background technique [0002] Fan maintenance personnel need to frequently lift the materials required for fan maintenance, and the lifting holes in the nacelle are generally designed at the bottom of the nacelle cover, so maintenance personnel often need to climb to the bottom of the nacelle to open and close the hoisting hole cover, and most of the fan nacelles The space between the hanging object hole and the rack is very small, which is extremely inconvenient and brings great safety hazards to the maintenance personnel of the fan. [0003] There are also hanging object hole covers that can be opened automatically in the prior art, mainly including a motor and a transmission mechanism. The motor drives the hanging object hole cover to open and close through the transmission mechanism, but the hanging object hole cover ...
