Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for loading induction electric appliances such as power transformers and reactors onto a trailer, and more particularly, relates to a method for loading induction electric appliances onto a trailer, which makes loading the induction electric appliances onto a trailer inexpensive and easy. .

Generally, when transporting induction electric equipment to a site, it is often loaded onto a ship and then transferred to a trailer before being transported to the site.

In this case, when directly loading induction devices from the ship or from the ship to the trailer, it is necessary to have the trailer on standby when the ship enters the port.

Especially if there are multiple cargoes, do you need multiple trays to match? When the number of trailers is less than the cargo, it is necessary to keep the ship on standby until the trailer transport work is completed.

In other words, although it is desirable to use trailers and ships efficiently in a short period of time, this is not possible, and transportation costs are extremely high.

° Also, once the induction electric equipment was lowered onto the quay from the ship or Kizuna, a floating crane or mobile crane was used to load it onto the trailer.

At this time, the crane truck and floating crane will be restrained until the trailer transport work is completed.
It was still uneconomical.

Therefore, the present invention was invented based on a novel idea with the object of providing a method for loading induction electric appliances onto a trailer, which eliminates the above-mentioned drawbacks, reduces transportation costs, and facilitates transportation work.

In order to achieve such an object, the present invention arranges two pairs of support structures each consisting of a plurality of square timbers stacked in multiple stages with an interval equal to or more than the vehicle width of a trailer, and each pair of support structures is The support beams are bridged, the spacing between the two pairs of support beams is set to a distance corresponding to the corresponding side walls of the tank, and the beam seats provided on the corresponding side walls of the tank are placed on the support beams. Then, the tank is supported by the support beam, and a jack is placed in the space except for one of the plurality of square timbers immediately below the support beam, or in the space between the plurality of square timbers, and with this jack, the support beam is is raised to remove the upper square beam of the support structure, and then the support beam is lowered by the jack and the tank is loaded onto the trailer that is placed between the two pairs of support structures. .

Here, an embodiment of a method for loading an induction electric appliance onto a trailer according to the present invention will be described with reference to FIGS. 1 to 3.

FIG. 1 shows an induction electric device, such as a transformer, used in this embodiment.

As shown in FIG. 1a, beam seats 2a and 2b are formed at the bottom of the side walls 1b and the IC, which form a pair of both longitudinal end faces of the tank 1a of the transformer 1. .

The beam seats 2a, 2b have a structure in which the side wall 1b and the lower part of the IC are notched.

In addition, as the beam seats 2a and 2b, as shown in FIG. A part of the side wall 1b and reinforcement (not shown) protruding from the IC may be used.

When the transformer 1 having the beam seats 2a and 2b is to be unloaded from the main ship or floating crane ship 3 shown in FIG. Item 6 is being assembled.

As shown in Fig. 3a and l), this support structure 6 consists of two pairs (two sets) of support stands made by combining square timbers 4 at intervals equal to or wider than the vehicle width of a trailer 7b towed by a tractor 7a. Furthermore, this support structure 6 is the beam seat 2a of the tank 1a.

They are arranged in correspondence with the spacing between 2b.

Since the trailer 7b will fit between the support structures 6, the height of the support structures 6 should preferably be at least this height.

On the support structure 6 are beam seats 2a and 2b of the tank 1a.
Two support beams 5 are bridged with a space between them.

When the transformer 1 is brought ashore from the main ship or the floating crane ship 3 to the support structure 6 assembled on the quay,
The transformer 1 is suspended by the crane 3a and placed on the support structure 6 so that the beam seats 2a and 2b are placed on the support beam 5.

After the unloading is completed, the main ship or the floating crane ship 3 does not need to be berthed.

Next, when loading the transformer 1 onto the trailer 7b, a jack 8 is installed on the support structure 6 stacked in multiple stages, the transformer 1 is lifted up, and the upper square timber is removed, and the transformer 1 is lowered and loaded onto the trailer. I am trying to load it into 7b.

In other words, there are no jacks in this space except for one of the square timbers 4 located directly below the support beam 5 at the top of a plurality of square timbers 4 stacked in multiple stages (three stages in Figures 2 and 3). 8 and lift the support beam 5 with the jack 8, then remove at least the square beam 4 supporting the support beam 5 of the uppermost square beam 4, and then lower the support beam 5 with the jack 8 onto the trailer 7b. The bottom of the tank of the transformer 1 is placed on it, and the transformer 1 is loaded onto the trailer 7b.

In this case, when assembling the support structure 6, the support beam 5
If a space is created in advance immediately below the support beam 5 adjacent to the uppermost square piece 4 that supports the jack 8, it is not necessary to remove the square piece 4 in order to place the jack 8 thereon as described above.

Further, the trailer 7b may be moved between the support structures 6 and stopped before the jack 8 is lowered.

The tractor 7a can be started by removing the support beam 5 on the tractor 7a side on the trailer 7b.

It goes without saying that the height of the support beam 5 is made smaller than the height of the side wall from the bottom of the transformer 1 to the beam seats 2a, 2b so that the support beam 5 can be removed.

In the above embodiment, a transformer is used, but the present invention can also be applied to other induction electric devices such as those transported by trailer transport.

As embodied in the above embodiments, according to the present invention, two sets of induction electric devices each having a beam receiver formed at the lower part of both side walls serving as a pair of tanks are formed by combining square timbers at an interval equal to or more than the vehicle width of a trailer. A support structure in which two support beams are bridged at a distance between the beam seats is loaded on a support base so that the beam seats are placed on the support beams, and then a jack provided on the square timber is loaded. By lowering the support beam, the induction electric equipment was unloaded and loaded onto the trailer passed between the support stands, and at the local port the induction electric equipment could be placed freely on the ship or on the support structure from the bond. The transportation work of the ship and trailer can be separated, so there is no need for a ship or a bond after unloading, there is no need to have a trailer on standby, and the number of support structures can be reduced even when multiple induction electric devices are brought ashore. It is sufficient to increase the number of units, which makes transportation costs extremely low and transportation work extremely easy.
