Abstract

PURPOSE:To improve the efficiency of utilization of a building and of transportation operation by a method wherein an electric machinery main body is hung down by a crane at an entrance of a conveyer and accessory machines are attached to the machine in itself while they are hung down by the crane. CONSTITUTION:At first an electric machine main body 2A is hung down by a crane 3 with a rope 4 into a vertical conveyer 1A to a basement and put down on the bottom of it. Then an accessory machine 2B is hung down close to the machine in itself 2A put on the bottom of the vertical conveyer 1A with the rope 4 in the same way and is attached to the machine main body 2A while it is still hung. Other accessory machines 2C-2E are attached to the machine main body 2A successively in the same way. After the necessary accessory machines are attached, the electric machine is conveyed to a setting-up place 1C through a horizontal conveyer 1B in the basement to the direction of an arrow B with horizontal transportation means such as rolls, rollers or air bearing.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for transporting heavy equipment such as a transformer to an installation location within a building such as an underground transformer.

FIG. 1 shows a conventional method of transporting power equipment for installation in a building to a location where it is installed in a building.

In Figure 1, (1) is the building, (IA) is the underground vertical conveyance path formed inside the building, (IB) is the horizontal conveyance path also on the ground, and (IC) is the location where power equipment is installed in the room. , (2) is a power equipment consisting of a transformer, (2A) is the main body of the power equipment,
(2B) (2G) are accessories of power equipment, (2B
) is the load tag changer storage tank, and (2C) is the conservator. (3) LT crane, (4) is a hanging rope.

Conventional power equipment (2) 11 locations in the building (IC)
To transfer the equipment, first, the power equipment (2) is suspended by the crane (3) via the lobe (4), and then lowered as shown by arrow A in the vertical transport path (IA), and then as shown by arrow B. like,
The material was transported through a horizontal transport path (IB) to an installation location (IC) using a horizontal transport means such as rollers, air bearings, etc.

However, in such a transfer method, the attached equipment (2B) (2
”:) is caused by the swaying of the power cable (2) in the direction of the I-tomo force and the rotation of the rose (4) by 17 degrees, causing the 1llll vertical conveyance path (
If the two forces (1~) are biased against the wall of IA), or if the rope (4) is suspended with the attached equipment (2B) (2C) in contact with the VC, the contact 1 (1) may be damaged by 4N. Therefore, the work must be extremely careful and take a long time.
IA)'s 4L from a two-dimensional view! i is made wide to ensure that the attached equipment (2B) (2c) will not be damaged even if the power equipment (2) swings laterally or rotates around the rose (4). As a result, we considered whether there was a way to reduce the planar area of the transfer path (IA) without damaging the Kv (2") (2C), as shown in Figure 2. I first devised a method for this.

It should be noted that this vertical conveyance path (CIA) was designed to reduce the planar area of the vertical conveyance path (IA).
Since it is only used for transporting the container (2) and has no use after transport, it is better to make this planar area as small as possible to improve the building's profitability (Detail 11) 7 costumes/
That's it.

Figure 2 shows that without attaching 4 machines rr4 (2B) (2C) to Fuyu (2), first, only the main body (2) was suspended in the 4 transport path (IA), and then (Yellow 1 general route (I B, l 4 prefix, 1 subdued ii'j 14 force tsusho (

Transport it to the installation location 1') (IC), and use the chain glock (5) on the main body (2) at the installation location 1') (IC). (2G) However, although this method can eliminate the disadvantages of the conventional method shown in Figure 1, it is necessary to install and space the area (1c) from the ceiling (1c).

4 equipment (2B) (2C) It is necessary to withstand the east 1k of (2C), and the number of general transports in the horizontal conveyance path (IB) increases by the attack of 4 equipment (XJ' j < 4 equipment). Another drawback arises in that it becomes worse.

Therefore, we have developed a method that eliminates the drawbacks of the conventional method shown in Figure 1 and the improved method shown in Figure 2, without increasing the height of the installation location. The purpose of this light is to provide a method for transporting the stirrer. be.
