[ detailed description ] of the utility model
For the purposes of promoting an understanding of the principles and advantages of the utility model, reference will now be made to the drawings and specific examples, it will be apparent that the utility model will be illustrated in some, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1, the embodiment provides a disassembly tool for an air passage stay of a dry-type transformer die, which comprises a horizontal connecting plate 1 and vertical connecting plates 2 respectively connected to two sides of the horizontal connecting plate 1 in the width direction, wherein a plurality of connecting holes 3 are uniformly formed in the two vertical connecting plates 2 along the length direction of the two vertical connecting plates respectively, the connecting holes on the vertical connecting plates are in one-to-one correspondence, and when the disassembly tool is used, the connecting holes on the vertical connecting plates are aligned with the holes on the air passage stay, and then the disassembly tool is connected by utilizing pins or bolts and nuts; the lengths of the connecting holes 3 are sequentially increased from left to right, and the upper ends of the connecting holes are positioned on the same horizontal plane, namely, the connecting holes except the leftmost connecting hole are all strip-shaped holes; when the device works, firstly the leftmost airway stay is pulled out for a certain distance, and then the second airway stay is pulled out for the left number, so that the force is distributed, and the difficulty in pulling out a plurality of airway stays simultaneously is reduced.
