Description

Transformer core is folded rockover

[technical field]

The utility model relates to the folded rockover of a kind of transformer core, is specifically related to the technological improvement of lamination and the frock of standing up in the middle-size and small-size transformer core production process of a kind of 50kVA～4000kVA, belongs to the transformer technology field.

[background technology]

In present transformer industry, the lamination of middle-size and small-size transformer core mainly contains two kinds of ways with standing up.A kind of way is shown in Figure of description 1, and it will be sheared good silicon steel sheet folded folder on the desktop of lamination platform 5 ' and be shaped, and tangle the last yoke of iron core 1 ' again with driving drop hanger 3 ' and lifting rope 4 ', and iron core 1 ' is directly sling on lamination platform 5 '.Yet in this sling process, the stem of iron core 1 ' was easy to generate bending, " bending over " shape occurred, did not reach quality requirement, brought difficulty to next procedure.In order to address this problem, normally increase by one to two attached folder 2 ' at the stem middle part of iron core 1 ', a block plate then respectively fills up in the stem top and bottom in the producer that has, and uses adapter 2 ' to clamp again, and is not crooked in the process of standing up with the protection stem.The shortcoming of this way is that operation is loaded down with trivial details, and annex is more, the field management confusion.

Another kind of way is shown in Figure of description 2, and it is with iron core 1 " after the moulding of folded folder, put down with driving a vehicle and to hang a specific hydraulic roll-over table 2 " on overturn and stand up.The shortcoming of this way is to invest greatlyyer, and cost is higher, has increased process route and station.

Therefore, for avoiding above-mentioned technical problem, the necessary more reasonably folded rockover of transformer core of a kind of structure that provides is to overcome described defective of the prior art.

[utility model content]

For addressing the above problem, the purpose of this utility model is to provide a kind of transformer core simple in structure, easy to use to fold rockover.

For achieving the above object, the technical scheme that the utility model is taked is: a kind of transformer core is folded rockover, it comprises lamination platform, steel wire rope, base, rotation trailing arm and feet, wherein, described lamination platform is connected by steel wire rope with base, described rotation trailing arm is installed on the lamination platform, described feet is connected on the lamination platform, further be provided with a guiding block on the described lamination platform, described base is provided with the deep-slotted chip breaker of accommodating guiding block, thereby described guiding block can overturn the lamination platform in the deep-slotted chip breaker activity.

The folded rockover of transformer core of the present utility model further is set to: described lamination platform is provided with the first fixation with steel wire end, described base is provided with the second fixation with steel wire end, and described steel wire rope two ends are separately fixed on the first fixation with steel wire end and the second fixation with steel wire end.

The folded rockover of transformer core of the present utility model further is set to: it further comprises a trailing arm rotating shaft, and described lamination platform articulates by this trailing arm rotating shaft with the rotation trailing arm.

The folded rockover of transformer core of the present utility model also can be set to: further be provided with a screw thread top handle on the described rotation trailing arm.

Compared with prior art, the utlity model has following beneficial effect: transformer core of the present utility model is folded rockover making simple in structure, easy, cost of manufacture is low, easy for installation, does not need electricity, water, and the G﹠O equal energy source, it is very convenient to acquire this frock.Effectively guaranteeing on a station, to finish lamination and the two procedures of standing up under the lamination unshakable in one's determination prerequisite convenient and that steadily upset is stood up, improved production efficiency.

Fig. 2 is the structural representation of the hydraulic overturn platform of another prior art.

Fig. 3 is the structural representation of the folded rockover of transformer core of the present utility model.

[embodiment]

See also shown in Figure 3ly, the utility model is the folded rockover of a kind of transformer core, overlappable transformer core 9 on it, and by the middle part of attached folder 8 fixing transformer cores 9 is set.

The folded rockover of described transformer core is made up of lamination platform 1, steel wire rope 2, base 3, members such as rotation trailing arm 4, feet 5 and trailing arm rotating shaft 6.Wherein, described lamination platform 1 is provided with the first fixation with steel wire end 11, and described base 3 is provided with the second fixation with steel wire end 31, described steel wire rope 2 two ends are separately fixed on the first fixation with steel wire end 11 and the second fixation with steel wire end 31, thereby make lamination platform 1 be connected as a whole with base 3 by steel wire rope 2.Described rotation trailing arm 4 is installed on a side of lamination platform 1, and described lamination platform 1 articulates by this trailing arm rotating shaft 6 with rotation trailing arm 4.Further be provided with a screw thread top handle 41 on the described rotation trailing arm 4, come spacing this iron core 9 thereby described screw thread top handle 41 withstands iron core 9 under the situation of tightening.Described rotation trailing arm 4 upper ends further are provided with a driving suspension hook 71, and described rotation trailing arm 4 is connected by a lifting rope 72 with travelling crane hook 71, and described travelling crane hook 71 can be sling rotation trailing arm 4.Described feet 5 is connected on the lamination platform 1.Further be provided with a guiding block 12 on the described lamination platform 1, described base 3 is provided with the deep-slotted chip breaker 32 of accommodating guiding block 12, thereby described guiding block 12 can be movable with 1 upset of lamination platform at deep-slotted chip breaker 32.Described steel wire rope 2 specifically can adopt flexible steel wire rope or chain, steel band etc., to pin down and to guarantee that lamination platform 1 is not along deep-slotted chip breaker 32 flip-flop movements and by landing.

The operation principle of the folded rockover of transformer core of the present utility model is as follows: will shear good silicon steel sheet after folded folder is shaped on the lamination platform 1, upwards upset is vertical the rotation trailing arm 4 of the downward hanging before the lamination, threaded together top handle 41 withstands unshakable in one's determination 9, to rotate trailing arm 4 with driving drop hanger 71 and lifting rope 72 again slings slightly, feet 5 is by the inside folding of eccentric deadweight, at this moment, driving being hung 71 slowly descends downwards again, utilize unshakable in one's determination 9 deadweight and eccentric center principle, thereby the guiding block 12 of lamination platform 1 is movable with 1 upset of lamination platform along the deep-slotted chip breaker 32 of base 6, be turned to vertical position until lamination platform 1 and unshakable in one's determination 9, and reversal rate depends on and iron core 1 is hung driving drop hanger decrease speed change next procedure over to then.

Above embodiment only is the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within made any modification, be equal to replacement, improvement etc., all should be included within the protection range of this creation.
