Combined uninstalling tool and method for generator stator bar leads binding thimble

Abstract

Provided a combined uninstalling tool and method for a generator stator bar leads binding thimble. The combined uninstalling tool comprises a top leads binding thimble uninstaller for uninstalling a top leads binding thimble, and a bottom leads binding thimble uninstaller for uninstalling a bottom leads binding thimble. The top leads binding thimble uninstaller comprises a top guiding shaft. A top hammering platform is fixed to the top end portion of the top guiding shaft. A top clamping groove operating head is fixed to the bottom end portion of the top guiding shaft. A top clamping groove is arranged on the center of the bottom of the top clamping groove operating head. A top motion arm hammer sleeves the top guiding shaft and is capable of moving up and down in the top guiding shaft. A bottom motion arm hammer sleeves a bottom guiding shaft and is capable of moving up and down in the bottom guiding shaft. A bottom handle is fixed to the side end of a bottom hammering platform. The combined uninstalling tool is simple in structure, easy to use and operate, capable of effectively preventing body scald and stator bar damage and deformation, greatly shortening an overhaul period, and improving uninstalling work efficiency.

Description

technical field [0001] The invention relates to a combined dismantling tool and a dismantling method for a generator stator wire rod and cover, and belongs to the technical field of generator stator maintenance. Background technique [0002] The stator bars of the generator are evenly distributed inside the silicon steel sheets of the generator stator, and embedded in the slot wedges superimposed by multi-layer silicon steel sheets; the stator parallel cover includes the upper parallel cover and the lower parallel cover, respectively made of copper metal material Made of tin, the surface layer is silver-gray, and their function is to cover and weld the stator bar joints up and down, so that the bars are connected in series to form a conductive coil. [0003] In the maintenance of the stator of the generator, whether it is to replace the stator bar, or to deal with problems such as poor conduction at the joint of the bar joint, the parallel part of the bar must be removed fir...

AI Technical Summary

Problems solved by technology

[0005] (1) Unsafe operation: if the traditional method is used for dismantling, the high-temperature headgear and splashing welding slag can easily cause burns to the human body; This removal method will cause uneven force on the headgear, which will cause damage and deformation of the wire rod joints

[0006] (2) Low work efficiency: This work requires the cooperation of two people, and manual work at close range under the high temperature state of the headgear makes the staff nervous

Moreover, the stuck position of the headgear is uncertain, it is difficult to use force, the construction progress is slow, and there may even be repeated melting due to failure to hit and pull out in time, which is more time-consuming and labor-intensive
