Abstract
The utility model relates to a pull tape fastening structure of a transformer, and belongs to the technical field of manufacturing of transformers. According to the technical scheme, the pull tape fastening structure of the transformer comprises a pull tape (1), a pull tape screw rod (2), a pull tape nut I (2), a pull tape nut II (4) and a clamp body (5), wherein the pull tape screw rod is arranged on the pull tape and penetrates through the clamp body, the pull tape nut I is installed on the pull tape screw rod at the outer side of the clamp body, the pull tape nut II is installed outside the pull tape nut I, and a pneumatic tensioning device is installed on the pull tape screw rod at the outer side of the clamp body. The pneumatic tensioning device is started until the tensioning force meets the requirements, the pull tape nut I is fastened. The pneumatic tensioning device is taken down, and the pull tape nut II (4) at the outer side of the clamp body is installed. The pull tape fastening structure of the transformer has the advantages that an air pressure device is adopted to be fixed to the pull tape screw rod to tension the pull tape, the nuts are screwed up after the set tension is reached, the pull tape screw rod is free of torsion moment, and the pull tape is good in tensioning effect.
Description
Technical field
The utility model relates to a kind of drawstring fastening structure of transformer, belongs to technical field of transformer manufacturing.
Background technology
At present, generally tighten by torque spanner between transformer pull band screw rod and clamp nut, easy damaged drawstring screw rod as excessive in screw-down torque even causes the drawstring distortion, so screw-down torque is limited, the drawstring tension effect is poor.
The utility model content
The purpose of this utility model is to provide a kind of drawstring fastening structure of transformer, adopt pneumatic shuttle to be fixed on the drawstring screw rod drawstring is strained, fastening nut after arrival appointment pulling force, the drawstring screw rod is not subjected to moment of torsion, the drawstring tension effect is good, solves the problems referred to above that background technology exists.
The technical solution of the utility model is:
A kind of drawstring fastening structure of transformer, comprise drawstring, drawstring screw rod, drawstring nut one, drawstring nut two and folder, the drawstring screw rod is installed on drawstring, the drawstring screw rod passes folder, drawstring nut one is installed on the drawstring screw rod in the folder outside, drawstring nut two is installed in the outside of drawstring nut one.
Described drawstring, middle part are band steel, and two ends are round steel structure with threaded hole; Drawstring screw rod, TBE (threaded both ends) are connected with drawstring and drawstring nut respectively; The drawstring nut, quantity is two, is respectively drawstring nut one and drawstring nut two, the upper surface of drawstring nut two is circular arc, can play the radome effect.
Good effect of the present utility model: adopt pneumatic shuttle to be fixed on the drawstring screw rod drawstring is strained, fastening nut after arrival appointment pulling force, the drawstring screw rod is not subjected to moment of torsion, and the drawstring tension effect is good.
