Description

Technical Field [0001] The present invention relates to a power supply device for an indoor work construction heavy equipment,

[0001] The present invention relates to a power supply apparatus for a construction heavy equipment, and more particularly to a power supply apparatus for a heavy construction equipment for indoor work which can maintain the tension of a power line for supplying power for driving within a working range in a heavy equipment work such as an electric excavator .

Generally, since heavy construction equipment such as an excavator and a crane is equipped with traveling means for moving, it is constructed so that necessary power can be obtained by burning fuel such as light oil and driving the engine.

Conventionally, such heavy construction equipment such as excavators has been used in a variety of fields used in the construction site, the casting factory, or the waste disposal site for transporting the underground scrap or scrap metal to a cutter or a compressor.

Construction heavy equipment such as an excavator used for the above purpose uses fuel such as light oil to drive the engine though it is not necessary to travel at a long distance.

Therefore, noise is generated at the time of starting the engine, and the maintenance cost is high because the fuel is expensive, and pollution of the atmosphere is caused by the generation of the smoke gas when the engine is operated. In particular, there is a problem that the soil is contaminated by leakage of oil and oil.

Therefore, electric power is supplied to heavy construction equipment such as an excavator working in a certain radius, and the hydraulic pump is driven by a motor, so that it is modified and used so as to achieve a desired purpose.

However, since the heavy equipment such as the excavator that has been modified in this way continuously moves within the working radius, there is a problem that the electric wire is damaged and the electric supply is interrupted or the electric wire is interfered with, so that it can not smoothly move within the working radius.

In order to solve such problems, various technologies have been proposed. However, in the case of a seesaw type which is structurally complicated and particularly designed to enable the use of electric wires flexibly, there is no means to control the excavator even if it deviates from the working radius Therefore, there are frequent cases of disconnection, which leads to a decrease in work efficiency and a high maintenance cost.

Accordingly, when an electric excavator is used, electric power is supplied through a power line installed along a rail mounted on a ceiling inside the building in accordance with the environmental regulation in the indoor environment, and the electric excavator is driven along the rail mounted in the longitudinal direction of the building A need has arisen for an indoor power supply device in which the operation radius is secured in accordance with the direction of rotation of the boom.
