The steel cable I (2) is matched in the groove of the pulley (1) in a sliding manner; the iron rings (3) are arranged at both ends of the steel cable I (2); the length of the steel cable I (2) is larger than the total sum of the length of the longer side of an iron core (7) and the extension length of a clamping device in the direction of the longer side of the iron core (7); two steel cables II (4) are respectively matched in the holes of the iron rings (3) at both ends of the steel cable I (2) in a sliding manner; and iron hooks (5) are arranged at both ends of the steel cables II (4). The utility model has the advantages of simple structure, smooth and reliable use, strong safety, high work efficiency, convenient maintenance and low cost.

Description

The transformer core turning device

Technical field:

The utility model belongs to the transformer technology field, particularly relates to a kind of transformer core turning device that is used for.

Background technology:

In the transformer manufacture process, 90 degree need overturn iron core when the iron core closed assembly finishes.Present known turning device is an iron core special overturn platform, and a kind of form is that support and arc leg constitute, the another kind of fluid pressure type flipped form that adopts.All there is the equipment complexity in two kinds of forms, maintenance difficult, production cost height, shortcomings such as inefficiency.Easy way can utilize driving with the flat ground that winches to of iron core usually; implement upset in vertical lifting of iron core again; iron core column can be distorted because of unbalance stress like this; and in the process of upset; after the focus point of iron core had been crossed rotating fulcrum, it can swing to opposite side with acceleration, and this upset mode is big to the impact of ground and workpiece; destructive strong, poor stability.

The utility model content:

The purpose of this utility model provides a kind of simple in structure, steadily reliable, high efficiency, fail safe is good, easy to maintenance and cost is low transformer core turning device.

Technical solution adopted in the utility model is: described transformer core turning device, comprise wirerope, it also comprises pulley and iron hoop, wirerope I sliding fit is in the groove of pulley, wirerope I two ends are provided with iron hoop, the length of wirerope I is greater than the long edge lengths of iron core and adds anchor clamps two times in its long side direction development length summation, two wirerope II difference sliding fit is in the hole of wirerope I two ends iron hoop, wherein the two ends of a wirerope II flexibly connect with the base location hole of iron core anchor clamps respectively, and the two ends of another root wirerope II flexibly connect with the lifting hole(eyelet) of iron core opposite side anchor clamps respectively.

Described flexible connection refers to that the two ends of wirerope II are respectively equipped with the cleek that articulates with anchor clamps location hole and lifting hole(eyelet).

After adopting above structure, the utility model compared with prior art has following advantage:

1, because the utility model has adopted the structure of pulley, wirerope and iron hoop, after the two ends of wirerope II flexibly connect with clamp base location hole and lifting hole(eyelet) respectively; In the lifting process, iron hoop can slide into the position of centre of gravity of wirerope II automatically because of the effect of iron core gravity, has guaranteed that the iron core level lifts by crane stably; After iron core lifts by crane in the air, use manpower because of the effect of pulley and can realize upset aloft easily, thereby realize the upset that iron core is steadily safe, to ground and the no any damage of iron core itself, so high safety, high efficiency;

2, the utility model only is that common pulley, wirerope and iron hoop are formed, and is simple in structure, keeps in repair very conveniently, and cost is low.

Description of drawings:

Structural representation when Fig. 1 slings the workpiece level for the utility model

Structural representation when Fig. 2 is the utility model with workpiece upset back plumbness

As shown in the figure: 1, pulley, 2, wirerope I, 3, iron hoop, 4, wirerope II, 5, cleek, 6, lifting hole(eyelet), 7, iron core, 8, location hole.

Embodiment:

The utility model is described in further detail below in conjunction with specific embodiment:

See Fig. 1, Fig. 2, the transformer core turning device is made up of pulley 1, wirerope I2, iron hoop 3, wirerope II4 and cleek 5.The two ends, long limit of iron core 7 are provided with anchor clamps, and the left end anchor clamps are provided with base location hole 8, and the right-hand member anchor clamps are provided with lifting hole(eyelet) 6.The skeleton of pulley 1 is hung on the suspension hook of driving, wirerope I2 pass in the groove of pulley 1 and with the groove sliding fit, the length of wirerope I2 adds anchor clamps two times in its long side direction development length summation greater than iron core 7 long edge lengths, an iron hoop 3 is respectively overlapped by " U " font folder in the two ends of wirerope I2, respectively establish a wirerope II4 and its sliding fit in the hole of two iron hoops 3, the two ends of these two wirerope II4 respectively are provided with a cleek 5 by " U " font folder, the cleek 5 at wirerope II4 two ends is hooked on the lifting hole(eyelet) 6 of iron core 7 right-hand member anchor clamps, and the cleek 5 at another root wirerope II4 two ends is hooked on the base location hole 8 of iron core 7 left end anchor clamps.

When iron core 7 liftings, iron hoop 3 slides into the position of centre of gravity of wirerope II4 automatically because of the effect of iron core 7 gravity, make that iron core 7 levels are sling stably, when 7 of iron cores winch to certain altitude (not running into ground when extremely overturning aloft gets final product), the past direction that need overturn is with hand or draw iron core 7, wirerope I2 will drive pulley 1 and roll towards this direction, thereby can realize upset easily, treating only needs to utilize driving that it is moved on to put area after iron core 7 upsets put in place, slowly put back to ground, take out cleek 5 and get final product.

The utility model not only is confined to above embodiment, also allows other structural change, as: wirerope II need not establish cleek, and two ends are directly passed usefulness " U " the font folder that turns back behind lifting hole(eyelet) or the location hole and are fixed into a ring-type and get final product.
