Abstract

The utility model relates to a pay-off bracket, in particular to a pay-off bracket used during transformer coil winding. The pay-off bracket comprises a bracket part used for mounting at least 4 groups of rollers of a pay-off spool, wherein the rollers are mounted on the bracket part horizontally through two bearings; the pay-off bracket is characterized in that the bracket part is wedge-shaped, and welded by angle steel; the bottom of the bracket part is fixed on the ground through bolts; and the rollers are arranged parallelly along an upper inclined plane. With the adoption of the pay-off bracket, multiple pay-off spools can be mounted, and the pay-off bracket can be shared by many people.

Description

Multiple pay off rack

Technical field

The utility model relates to a kind of wire-unfolding rack, the wire-unfolding rack that particularly uses during a kind of transformer coil winding.

Background technology

The transformer capacity of using now is larger, and is also larger on the impact of electrical network, requires its fail safe also more and more higher.The workmanship performance of transformer not only requires electric property reliable, and mechanical stability, anti-short circuit capability also should be more reliable.Stability is mainly manifested on the manufacture process control of coil, namely requires the high-voltage coil and low-voltage coil electromagnetic balance, axially turn-to-turn closely, be evenly distributed.Therefore require the coil winding process, radially will roll tightly, axially close-packed arrays.The coil winding process is that the draw drum that will be wound with enamelled wire is installed on pay off rack, and iron core is arranged on tensioning apparatus, and tensioning apparatus rotates to be wound around enamelled wire, and the hand-held enamelled wire of workman is adjusted winding position to guarantee coil axes to turn-to-turn closely.

Although existing pay off rack can satisfy the demand of unwrapping wire to a certain extent, but it still exists certain problem, be in particular in: 1, owing to may needing multiple enamelled wire in the coil winding process, and different enamelled wires is normally on different draw drums, therefore the workman usually needs to adjust frequently and change draw drum, to adapt to different coiling requirements; 2, adjacent or relative several workmans more need with a pay off rack, draw drum to be installed separately usually in addition, and a large amount of draw drum costs drops into and safeguards all larger.

The utility model content

The technical problems to be solved in the utility model is to provide a kind of a plurality of draw drums of installing, and the pay off rack that can many people shares.

In order to solve the problems of the technologies described above, the utility model provides a kind of multiple pay off rack, include support, in order to the roller bearing of draw drum to be installed, this roller bearing is rack-mount by two bearing levels, puts up truncated wedge for described, is made of the angle steel welding, its bottom is bolted ground, and described roller bearing is arranged with at least 4 groups in parallel along ramp.

adopt the multiple pay off rack of technique scheme to have following advantage: owing to including support, in order to the roller bearing of draw drum to be installed, this roller bearing is rack-mount by two bearing levels, put up truncated wedge for described, consisted of by the angle steel welding, its bottom is bolted ground, described roller bearing is arranged with at least 4 groups in parallel along ramp, so it is relatively simple for structure, the at least 4 group roller bearings that be arranged in parallel on the inclined-plane can be installed 4 draw drums at least, it is poor that draw drum has certain altitude, avoided interference each other, it both can install for a workman draw drum of different size, also be beneficial to the draw drum that different workmans install to be needed separately, therefore the pay off rack utilization is more efficient.

As preferred version, for the demand of balance workman to coil quantity, and the floor space of device, limit described roller bearing and be arranged with 8 groups in parallel.

As preferred version, drop from roller bearing in order to prevent draw drum, be convenient to simultaneously install the draw drum of different size, support side 40cm is stretched out at described roller bearing two ends, which is provided with the fixedly nut of draw drum.

Description of drawings

Fig. 1 is the main TV structure schematic diagram of the multiple pay off rack of the utility model embodiment;

Fig. 2 is the side-looking structural representation (roller bearing has only indicated a group) of the multiple pay off rack of the utility model embodiment.

Embodiment

Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:

As depicted in figs. 1 and 2, the utility model provides a kind of multiple pay off rack, include support 1, in order to the roller bearing 3 that draw drum 2 is installed, roller bearing 3 is arranged on support 1 by two bearing 4 levels, 1 one-tenth truncated wedge of support, be made of angle steel welding, support 1 bottom is bolted ground, and roller bearing 3 is arranged with 8 groups in parallel along ramp, support side 40cm is stretched out at roller bearing 3 two ends, and roller bearing 3 is provided with the fixedly nut 5 of draw drum.

According to the actual requirements, on truncated wedge support 1, the quantity setting of parallel roller bearing 3 can be done free adjustment.

Above-described is only preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection range of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.

Claims

1. multiple pay off rack, include support, in order to the roller bearing of draw drum to be installed, this roller bearing is rack-mount by two bearing levels, it is characterized in that: put up truncated wedge for described, be made of the angle steel welding, its bottom is bolted ground, and described roller bearing is arranged with at least 4 groups in parallel along ramp.

2. multiple pay off rack according to claim 1, it is characterized in that: described roller bearing is arranged with 8 groups in parallel.
