Large transformer coil turn-over apparatus and coil turn-over method

Abstract

The present invention discloses a large transformer coil turn-over apparatus and a coil turn-over method. The turn-over apparatus comprises a base and a turn-over mechanism. An outer contour of the turn-over mechanism is a convex arc surface. A first mounting plate and a second mounting plate perpendicular to each other are disposed inside the turn-over mechanism. A sliding rail is disposed on thefirst mounting plate, and a first arc bracket and a second arc bracket are installed above the sliding rail. Positions of the two brackets can be adjusted by using a hand wheel according to a coil height. A rubber sheet is laid on an inner side of the arc surface, to protect a coil surface, and prevent a coil from being damaged. A drive chain is disposed on the arc surface outside the turn-over mechanism along a turn-over direction. A speed reducer and a transmission gear are disposed inside the base. The speed reducer uses the transmission gear to drive the drive chain on the turn-over mechanism to implement turn-over of the turn-over mechanism, and a position limiting structure is used for implementing accurate control of a turn-over position. According to the large transformer coil turn-over apparatus and the coil turn-over method, safe and stable turn-over of the large transformer can be implemented, production efficiency is improved, burden of operating personnel is lowered, coilcollision is avoided, and coil intactness is ensured.

Description

technical field [0001] The invention belongs to the field of power transformer manufacturing, and relates to a large-scale transformer coil overturning device and a coil overturning method. Background technique [0002] Transformer coils need to be turned over after winding in the production process. Commonly used transformers are turned over by driving a car. Large-scale power transformers are turned over on a flatbed due to their large coil height (about 2 meters) and outer diameter (about 1.3 meters). , During the turning process, the mold is very close to the flatbed car and the coil shakes greatly, which may easily cause a series of problems such as wire cake falling off, coil collision, mold damage, etc. Contents of the invention [0003] Purpose of the invention: In view of the problems in the prior art, the purpose of the present invention is to provide a large-scale transformer coil turning device and a coil turning method, so as to realize safe and stable turning...
