Problems solved by technology

Moreover, due to the different on-hook time, the glass fiber reinforced plastic nacelle cover will be deformed to varying degrees.
These factors would make the reconfigured load hole cover curvature not suitable for all nacelles
The radian of the hanging object hole cover cannot be completely conformed to the shape, there is a certain gap between the nacelle cover and the hanging object hole cover, and the original pin on the nacelle cover cannot fix the hanging object hole cover
Even some pins are broken, missing
At the same time, most of the hanging object holes in the cabin are very small from the frame space, so reinstalling, adjusting the bolts, or adding other fixing mechanisms to the cabin cover are not easy to operate, and will bring great safety hazards to the operators

Abstract

The invention discloses a fixing structure of a hanging hole cover of a cabin cover. The fixing structure comprises a sleeve and an L-shaped bolt. The sleeve comprises a fixing flange and a cylinder which are integrally formed and is fixedly arranged at the edge of the inner surface of the hanging hole cove, and the cylinder is close to the exterior of the cabin cover and is vertically provided with a groove; the L-shaped bolt comprises a stud and a chuck which are integrally formed, the chuck is used for fastening the cabin cover, and the cylinder of the sleeve sleeves the L-shaped bolt; thestud of the L-shaped bolt can rotate and move up and down in the cylinder of the sleeve to drive the chuck to move up and down along the groove of the cylinder, so that the chuck is close to the exterior of the cabin cover and tightly clamps the cabin cover. The fixing structure is simple, compact, stable, reliable and low in cost; the fixing structure is safe and reliable, additional high-altitude installation operation is not needed, operators do not need to lean out of the cabin cover for installation and adjustment, and the risks of the operators are reduced; the fixing structure is convenient to use, and the hanging hole cover of a cabin of a wind generation set can be conveniently and quickly opened and closed through press rotation.

Description

technical field [0001] The invention relates to the field of wind power generator attachments, in particular to a fixing structure for a hole cover of a nacelle cover. Background technique [0002] Wind power generators usually need to install a tower with a height of more than 60m from the ground, and the generator set is installed on the top of the tower. When maintaining and overhauling the unit, the operator needs to hoist the required materials into the engine room. Therefore, the nacelle hanger hole is generally designed at the bottom of the nacelle cover. There is a hanging hole cover on the hanging hole, which is closed in daily life and opened when lifting materials. The traditional hanging object hole cover is detachable, that is, it can be completely removed from the hanging object hole. When installing, put the hanging object hole cover on the hanging object hole, insert the C-shaped buckle on one side, and fix the other side with a bolt after placing it prope...
