Detailed ways

Fig. 1 is a structural schematic diagram of the present utility model, as shown in the figure: the special spreader for the transformer with air channel pouring coil in this embodiment, the transformer with air channel casting coil 7 is provided with a vertical through air channel, the transformer with air channel The special spreader for casting coils in the air channel includes at least one set of spreader components; the spreader component includes a pull plate 1 and a bolt 2; the cross section of the pull plate 1 is not larger than the cross section of the air channel; one end of the pull plate 1 is The lifting end used to connect with the sling, the other end of the pull plate 1 is provided with a socket 3 for the horizontal insertion of the bolt 2; the length of the bolt 2 is greater than the maximum diameter of the air passage, so the pull plate 1 is inserted into the transformer with air passage Cast the air passage of the coil 7 and stretch it out to expose the socket 3 on the pull plate 1, then insert the pin 2 into the socket 3, use a lifting device such as a crane to connect to the lifting end of the pull plate 1 through a sling, and then the transformer can be installed. Lifting the cast coil 7 with air passage facilitates the assembly between the spreader assembly and the cast coil 7 with air passage of the transformer, saves time and manpower, reduces costs, and creates a stable connection between the pin 2 and the cast coil 7 with air passage of the transformer. At the same time, under the pressure of the transformer with air channel casting coil 7, a stable friction force can be generated between the bolt 2 and the pull plate 1 to prevent the bolt 2 from moving, so the spreader assembly and the transformer with air channel casting coil There is no relative movement between 7, which can avoid scratches on the coil surface and displacement of coil pads; the lifting end of the pull plate 1 can be directly formed by opening a hole on the pull plate 1, or it can be installed on the pull plate 1 for easy passage The lifting lugs of the sling form the lifting end structure, all of which can achieve the purpose of the utility model; in this embodiment, the sling assembly is provided with two sets, and the two pull plates 1 of the two sets of sling assemblies are inserted along the transformer with air Assemble in two air passages that are symmetrical to the center line of the pouring coil 7 .

In this embodiment, the pin 2 is provided with a card slot 4 that can be snapped into the bottom side of the socket 3, and the pin 2 can pass through the card under the pressure of the casting coil 7 with air passage of the transformer or the gravity of the pin 2 itself. The slot 4 is stuck on the bottom side of the socket 3, so that the relative positioning between the bolt 2 and the pull plate 1 is prevented, and the movement of the bolt 2 is prevented, which effectively avoids scratches on the coil surface and displacement of the coil pad; the pull plate 1 is inserted vertically into the transformer belt In the air channel of the air channel pouring coil 7, the jack 3 is arranged horizontally along the pull plate 1, so when the pull plate 1 is placed vertically, the center line of the hole 3 is along the horizontal direction, and the bottom side of the jack 3 means that the lower end of the pull plate 1 is located The part below hole 3.

In this embodiment, the lifting end of the pull plate 1 is provided with a lifting ring 5; the lifting ring 5 is a U-shaped ring, and the opening of the U-shaped ring is connected to the lifting end of the pulling plate 1 through a pin bolt 6 and a nut, so The lifting rope can be passed through the lifting ring 5 to lift the pull plate 1, and the lifting ring 5 and the pin bolt 6 can be installed by drilling horizontally at the lifting end of the pull plate 1. The lifting ring 5 is a standard part, which can be directly purchased and used, which is convenient for the production of the lifting device. The hoisting equipment such as the crane in the prior art will have an impact on the casting coil 7 with air channel of the transformer and the spreader at the moment of lifting, which will easily cause the cast coil 7 with air channel of the transformer and the spreader to be deformed by the impact. The lifting end of the middle pull plate 1 is provided with a slider that slides and fits with the pull plate with a single degree of freedom along the length of the pull plate 1 and a spring that is supported between the slider and the pull plate 1 to provide downward elastic force for the slider. Holes for installing pin bolts 6 are provided on the slider, so that the lifting ring 5 is installed on the slider of the pull plate 1, so the spring between the slider and the pull plate 1 can be buffered at the moment of lifting to avoid damage to the transformer. Casting coil 7 and spreader with air channel cause bigger impact.

In this embodiment, the cross-sections of the pin 2 and the jack 3 are both rectangular, so that the pin 2 and the pull plate 1 are matched with a single degree of freedom along the center line of the jack 3, combined with the slot 4 on the pin 2 The structure can realize the precise positioning between the bolt 2 and the pull plate 1, so that the connection structure between the spreader assembly and the transformer casting coil 7 with air passage is stable and reliable.

Finally, it is noted that the above embodiments are only used to illustrate the technical solutions of the present utility model without limitation. Although the utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the utility model can be Modifications or equivalent replacements of the technical solutions without departing from the purpose and scope of the technical solutions of the utility model shall be covered by the claims of the utility model.
