Description

[Detailed Description of the Invention] The present invention relates to a conveying device for a transformer with a so-called soundproof wall, which is constructed by covering the outer periphery of a transformer body mounted and fixed on a base with a soundproof wall.

In recent years, transformers installed in substations and the like have been installed in buildings with soundproof walls, which are constructed by covering the main body of the transformer with a soundproof wall, in order to prevent noise pollution.

When this transformer with soundproof walls is shipped from the factory, trailers, freight cars, ships, etc. are known as general transportation methods, but among these transportation methods, especially when freight cars are used, tunnels etc. Due to this relationship, the transport limit is severely restricted.

For this reason, a method is adopted in which the transformer body and the soundproof wall are transported separately, unloaded and assembled on-site.

When assembling the transformer on-site, for example, when mounting the transformer body on the base or covering the outer periphery of the transformer body with a soundproof wall, lifting work using a lifting machine such as a crane is inevitably required.

However, since this transformer with soundproof walls is installed inside a building, it is difficult to lift it at the installation site.

For this reason, a method is generally used in which the transformer is unloaded in advance at a location where lifting work is possible, and the transformer body is covered with a soundproof wall and transported to the installation location by roller pulling.

However, transporting the soundproof wall while covering the outer periphery of the transformer body means that the transformer body and the soundproof wall are constructed separately, so they may collide with each other due to vibration or tilt during transport. For example, there is a risk of damaging the bushing mounting seat, etc. that protrudes from the cover of the transformer body, and in addition, the lower installation surface of the soundproof wall must be transported with the lower installation surface slightly raised above the installation position. This poses a problem in that the equipment must be transported in an unstable state, requiring careful attention to safety and a lot of effort, leading to an increase in installation costs.

The present invention was developed in view of the above-mentioned points, and its purpose is to stably transport a transformer body mounted on a base with a soundproof wall covering the outer periphery. The goal is to provide equipment.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 is a picture-shaped soundproof wall with an open lower end that is installed at the installation location and covers the outer periphery of the transformer main body 2, and the outer wall and the inner wall are each made of steel plates. In addition, a sound material is interposed between the outer wall and the inner wall.

The earth wall and side wall of this soundproof wall 1 have a hanging fitting 1a for hoisting the soundproof wall 1, a through hole 1b for passing through a bushing mounting seat 2a arranged on the cover of the transformer main body 2, etc. Through holes are opened for each member attached to the main body 2 and extending outward through the soundproof wall 1.

In addition, jack receivers 1C are integrally provided at least in four locations at the lower portions of both parallel sides of the soundproof wall 1, and a flange 1d is integrally formed outwardly protruding from the lower end periphery of the outer wall. A plurality of mounting holes are bored in the flange 1d for fixing it to the installation foundation.

On both parallel sides of the transformer main body 2, hanging ears 26 are integrally disposed at the upper part and jack receivers 2C are disposed at the lower part at at least four places.

Reference numeral 3 denotes a base on which the transformer main body 2 is mounted, integrally attached by welding or bolts, and fixed to an installation foundation (not shown) by anchor bolts or the like.

This base 3 is formed of a #finger-shaped frame made of H-shaped steel, etc., and has hooks 3 at its ends for performing roller pulling work.
A plurality of mounting seats 3b having mounting holes for fastening the mounting base to the mounting base are provided.

The base 3 also has mounting holes for fastening later-described support fittings 4 with bolts 6 on the upper surface of the ends of the base 3 at at least four locations extending from both parallel side walls of the transformer main body 2. 3C is drilled to multiple locations.

As shown in FIG. 2, the supporting metal fitting 4 has two strip-shaped pieces 4a and 4b of a certain length arranged vertically and parallel to each other, and a rib 4C is used between the two upper and lower pieces. They are integrally connected to form an H-shaped cross section.

A plurality of mounting holes 4d are bored in the lower piece 4b at one longitudinal end of the support fitting 4 at positions corresponding to the mounting holes 3C of the base 3, and the upper piece 4a at the other end is bored with a plurality of mounting holes 4d. is a plate-shaped guide piece 5 that stands upright with its side edges along the longitudinal direction.
are fixed together by welding.

The upper corner of the side edge 5a that stands upright and faces the one end of the guide piece 5 is formed to be inclined in an arc shape.

Furthermore, the support fitting 4 is attached to the transformer main body 20 as a mounted device.
The supporting metal fittings 4 are attached to the upper surface of the end portion of the base 3 extending from both side walls.
Place the lower piece 4b on one end of the
A bolt 6 is inserted through d, and the bolt 6 is removably tightened and fixed with a nut, and the soundproof wall 1 is arranged so as to extend outward parallel to the end of the base 3, and the soundproof wall 1 covers the outer periphery of the transformer body 2 and is tightened and fixed in a removable manner with a nut. When lowered, the flange 1d of the soundproof wall 1 is placed on the upper piece 4a of the other end of the support fitting 4, and the soundproof wall 1 is supported.

At this time, the outer peripheral edge of the flange 1d is the guide piece 5.
The soundproof wall 1 is placed on the supporting metal fitting 4 while maintaining the dimension X with the side wall of the transformer main body 2, as shown in FIG. Transformer body 2
A desired space 7 is formed between the soundproof wall 1 and the soundproof wall 1.

Next, transport using this device will be explained.

After unloading the transformer main body 2 at a position where lifting work is possible, it is mounted on the base 3 as a whole, and then the lower piece 4b of one end of the support fitting 4 is mounted on the top surface of the end of the base 3. Then, align the mounting holes 4d of the support metal fittings 4 with the mounting holes 3C of the base 3, insert the bolts 6, and tighten and fix them together with nuts. Extend to.

Next, the soundproof wall 1 is lifted up by a lifting machine such as a crane via the hanging fitting 1a, and placed on the upper piece 4a of the lowering support fitting 4, covering the outer periphery of the transformer main body 2.

At this time, the outer peripheral edge of the flange 1d of the soundproof wall 1 is guided and placed on the side edge 5a of the guide piece 5 inclined in an arc shape, so that it can be positioned as desired against the side wall of the transformer main body 2 without the need for positioning. It is placed with a space 7 formed therebetween.

In addition, if a transformer with a soundproof wall, which is constructed by covering the outer periphery of the transformer body 2 mounted on the base 3 with the soundproof wall 1, falls within the transport limit, the transformer installed on the base 3 at the time of shipment from the factory The soundproof wall 1 may be placed on the support fitting 4 so as to cover the transformer body 2, and then transported and unloaded as is.

Then, with the soundproof wall 1 placed on the support fitting 4 to cover the transformer body 2, the transformer body 2 is rolled and transported to the installation foundation using a hook 3a provided on the base 3.

Even if the soundproof wall 1 tends to shift to one side due to vibration or inclination due to the undulations of the ground during this rolling work, the side edge 5a of the guide piece 5 provided on the support metal fitting 4
Since the receiver is stopped and prevented, the soundproof wall 1 is not damaged by colliding with, for example, a bushing mounting seat 3a provided on the outer periphery of the transformer main body 2, and is transported in a stable state.

After transporting the transformer body 2 to the base 3, remove the parts for rolling work and place the transformer body 2 on the mounting seat 3b of the base 3.
For example, it is fastened and fixed to the installation foundation via an anchor bolt.

Next, apply a jack to the jack receiver 1C provided on the soundproof wall 1, lift the soundproof wall 1 slightly upward at that position, remove the support fitting 4 from the base 3 by removing the bolt 6, and lower the soundproof wall 1 using the jack. The flange 1d is placed on the installation foundation and fixed by bolts or the like into mounting holes (not shown) to complete the installation of the soundproof wall 1 and the transformer body 2.

In the above embodiment, the supporting metal fitting 4 is described as being formed of two vertically parallel pieces having an H-shaped cross section with ribs interposed therebetween, but it goes without saying that various modifications can be made without changing the gist.

As described above, the present invention includes removably attaching support fittings to the upper surface of at least four ends of the base that extend outward from both parallel side walls of the transformer body mounted on the base. A plate-shaped guide piece extending outward and having a side edge inclined in an arc shape toward the side wall of the transformer main body is fixed upright and integrally on the extending end of the support metal fitting, and The soundproof wall that covers the outer periphery of the transformer is placed on the support bracket and guided by the side edge of the guide piece for transportation. Since it is only necessary to cover the outer periphery of the soundproof wall and place it, there is no need to fasten them together, and the associated labor and materials can be omitted. A guide piece protruding from the metal fittings guides the product at an angle, making positioning easy, and since the soundproof wall is placed slightly above the base, the relationship with the ground during transportation is easy to see. 10,000-
Even if the soundproof wall tries to shift position due to vibration or inclination during transportation, it will be caught by the guide pieces and blocked, so it will not collide with various mounting seats provided on the outer periphery of the transformer body and damage them. It can be transported without any problems.

In addition, since the supporting metal fittings are attached to at least four locations on the upper surface of the end of the base, the soundproof wall can be placed in a stable state, and the attachment and detachment of the metal fittings is done only when the soundproof wall is operated. Since this can be easily done from the outside without providing a through hole, there is no need to provide a blind cover to close the operating through hole, and the trouble of closing it after installation can be omitted.

Furthermore, since the desired space is maintained between the outer periphery of the main body of the transformer with soundproof walls that has been transported to the installation foundation, there is no need to make positioning adjustments when installing the soundproof walls, making installation easier. It has a simple configuration, reduces installation costs, and improves work safety, which has practical effects.
