Description

[Detailed Description of the Invention] The present invention relates to a hanging device for a transformer tank, and more particularly to an improved hanging device that serves both for lifting and tightening the lid, and as a fixing rope during transportation.

An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 to 4, 11 is a tank equipped with a cooling panel 12 and houses the transformer body, 13 is a lid that closes off the upper part of the tank in which a sunrise bushing 14, etc. is arranged;
is a hanging device provided on the tank 11.

The hanging fitting device 15 includes a hanging fitting 16 fixed to the tank 11 and a holding fitting 21 and a holding fitting 2 that press down the lid 13 from above.
Auxiliary metal fittings 19 for screwing in bolts 22 for tightening 1
to be intimidating.

The hanging fitting 16 is a plate bent into a U-shape as shown in FIG. 3, and the open end side is fixed to the side surface of the tank 11 by welding with the U-shaped end facing vertically.

This hanging fitting 16 has a notch 1 on the lower side for hanging a lifting rope.
7 is formed, and a through hole 18 is bored above it through which an auxiliary fitting 19 for fastening is passed.

The through hole 18 is, for example, an elliptical hole that extends further downward in addition to the cross section of the auxiliary fitting 19, and the rope 23 for fixing during transportation is passed through the play part 18H of the through hole 18. There is.

Note that although the through hole 18 is an elliptical hole, the lower part may be rectangular, or the lower part may be widened toward the end, or may have an appropriate shape.

As shown in FIG. 4, the auxiliary fitting 19 is a bar with a semicylindrical cross section, and has a threaded hole 20 between the two sides, and is inserted into the through hole 18 of the hanging fitting 16 as shown in FIG.

21 is an abbreviated presser metal fitting, one end of which is the hanging metal fitting 1.
6 and is disposed so that the other end presses against the top surface of the lid 13.

Therefore, the lid 13 is fastened through the presser metal fitting 21 by passing a bolt 22 through the presser metal fitting 21 from above and screwing its tip into the screw hole 20 of the auxiliary metal fitting 18.

Conventionally, the hanging fitting 16 of this type of hanging fitting device had a through hole large enough to insert the fastening auxiliary fitting 19, so it was necessary to provide an independent rope hanging fitting on the tank to hang the fixing rope. there were.

Therefore, the disadvantage is that the number of metal fittings used increases, making it more time-consuming and costly to manufacture.

However, according to the present invention, as described above, in order to insert the fastening auxiliary fitting 19, the through hole 18 provided in the hanging fitting 16 is opened downward to a large extent and the fixing rope 23 for transportation is passed through the hole 18. Therefore, there is no need to provide a special metal fitting such as a rope hook, and the hanging fitting 16 can be used to hang the rope during transportation.

Therefore, the structure is simplified, manufacturing is easy, and costs can be reduced.
