[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is provided with a hydraulic jack at a position where it is engaged with a transport bracket of a transformer in order to facilitate loading / unloading of a transformer carried by a schnabel type trailer or a wagon. Transformer that can be used for loading and unloading workers.

An object of the present invention is to improve the workability of loading and unloading a transformer on a schnabel type trailer or a wagon, and it is possible to attach a loading / unloading worker who can improve the workability. Related to providing a transformer.

[0003]

2. Description of the Related Art In order to load and unload a transformer on a schnabel trailer or a wagon, it is necessary to attach a transport bracket to the transformer so that the transformer can be engaged with the schnabel trailer or a wagon.

[0004] When loading and unloading a transformer mounted with this transport bracket on a schnabel-type trailer or a wagon, it is necessary to attach or detach a connecting pin of the schnabel-type trailer or freight car engaged with the transport bracket. . In this case, it is a common operation to arrange a hydraulic jack at the lower part of the transport bracket, attach and remove the connecting pin while jacking up and jacking down the entire transformer.

[0005] Accordingly, the operation procedure for loading / unloading a transformer on a schnabel trailer or a wagon has some differences in loading or unloading work, but basically, a transport bracket and a schnabel trailer or a wagon are used. Since it is necessary to attach and remove the connecting pin of the freight car, it is necessary to work so that the connecting pin can be easily installed or removed while adjusting the position of the transformer up and down, left and right, front and rear with a hydraulic jack.

Therefore, when loading and unloading the transformer on a schnabel trailer or a wagon, a complete set of hydraulic jacks, hydraulic jack height adjusting equipment, and transformer temporary support bases are prepared around the transformer. In each case, it is necessary to carry out a setup change operation of equipment for adjusting the position of the transformer.

When loading a transformer, it is necessary to transport the transformer from a predetermined place to a place of a schnabel type trailer or a freight car. Rolling method, a sliding method using a winch or a slide jack, and a crane are used as transportation means. Although there are various types of transportation methods, in any case, once the transformer has been transported to the loading place, it is necessary to carry out a setup change work each time to adjust the position of the transformer, and the hydraulic jack and the hydraulic jack height adjustment Unless the equipment and transformer temporary support bases are set again, they cannot be loaded on the schnabel trailer or the wagon.

[0008] On the other hand, the same is true when the transformer is unloaded. After unloading, it is necessary to move to the specified place. In any case, such as roller pulling method, sliding method using winch or slide jack, or transport method using crane, etc., changeover work is required to adjust the position of transformer each time. It is necessary to reset the hydraulic jack and the equipment for adjusting the hydraulic jack height.

As described above, when loading and unloading the transformer, or when transporting from a predetermined location to a schnabel-type trailer or a wagon and transporting from a schnabel-type trailer or a wagon to a predetermined location, each time. Since it is necessary to carry out a changeover work to adjust the position of the transformer, the hydraulic jack, the equipment for adjusting the height of the hydraulic jack, and the transformer temporary support base must be reset, resulting in poor work efficiency. However, there was a problem in shortening the working time.

Here, as an example, a conventional freight car wholesale operation will be described with reference to FIGS.

In the case of freight car wholesale work, the number of trains handling freight cars is decreasing, and the number of wholesalers on the main line is increasing. Therefore, it is necessary to take measures to reinforce the main line and shorten the time required for the wholesale operation. Time cannot be reduced.

FIG. 6 shows a basic work process (transportation work from freight car wholesale to loading of a trailer) in the prior art freight car wholesale.

As is apparent from FIG. 5, in the transportation work from the freight car wholesale to the trailer, in order to adjust the position of the transformer,
At least four (A to D) setup change operations occur. The outline of the transformer transportation device is shown in FIGS.
(b) and FIGS. 3 (a) and 3 (b).

Reference numeral 1 denotes a transformer main body to be transported. Reference numeral 2 denotes a transport bracket attached to the transformer, and is a Schnabel-type freight car 3
(The pin also engages with the attachment of the schnabel trailer).

Reference numeral 6 denotes a body frame of a Schnabel-type freight car, 7 denotes a bogie, 8 denotes wheels of the freight car, and 9 denotes a rail.

The transport fitting 2 is equipped with a hydraulic jack 10,
Adjust the height of the transformer by the up and down operation of the hydraulic jack 10,
Remove the connecting pin 5. After removing the connecting pin 5, the transformer 1 is further lowered by the hydraulic jack 10, and the transformer 1 is temporarily received on the transformer temporary receiving stand 11. This series of operations requires that the height of the transformer 1 be reduced to a predetermined height.
During this time, the height of the hydraulic jack 10 and the transformer
Since it is necessary to work while adjusting the height and the like of 1, the setup work of the equipment 12 occurs several times.

[0017]

SUMMARY OF THE INVENTION An object of the present invention is to load and unload a transformer on a schnabel trailer or a wagon, or to transport a transformer from a predetermined location to a schnabel trailer or a wagon. When transporting from a trailer or freight wagon to a predetermined location, it is necessary to jack up and down the transformer between each work process, adjust the position of the transformer, and carry out equipment changeover work. is there. Therefore, the hydraulic jack, the equipment for adjusting the height of the hydraulic jack, and the complete set of transformer temporary receiving mounts must be prepared and reset each time, so that the workability is poor and much time is required.

In view of the above drawbacks, the present invention provides a transformer characterized in that a loading / unloading worker equipped with a hydraulic jack can be mounted at a position where it can be engaged with a transport bracket of the transformer. Reduce the number of times to carry out the work and reduce the number of times to prepare hydraulic jacks, hydraulic jack height adjustment equipment and a set of temporary transformer mounting racks to adjust the height position of the transformer each time The object of the present invention is to improve the workability and shorten the work process by reducing the necessity of resetting these equipments.

That is, since the transformer is jacked up and jacked down between the respective work steps, and the slide pulling can be performed as a continuous work of the series of work, the work time is reduced.

[0020]

A loading / unloading worker equipped with a hydraulic cylinder is mounted on a transformer on two sets of transport fittings attached at two positions facing the side of the transformer, and the hydraulic jack is provided. Is configured to be able to engage with the transport bracket.

Further, two hydraulic jacks attached to the loading / unloading worker are configured to engage with two sets of transport fittings, so that the transformer can be lifted by a total of four hydraulic jacks. .

The loading / unloading worker is composed of a hydraulic jack, a slide under the hydraulic jack, a mounting guide for preventing the whole from falling down by engaging with the transformer, and the like. It is structured so that it can be set on a slide rail that has been separately installed in the engaged state.

With this configuration, for example, when the transformer is hoisted by a winch or the like, the lower part of the slide slides on the slide rail, so that the entire transformer moves. Further, since the transformer and the loading / unloading worker are connected by the mounting guide, the loading / unloading worker does not fall when the transformer is moved.
