Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery storage device for a construction machine, and more particularly to a battery storage device for a small turning hydraulic excavator.

[0002]

2. Description of the Related Art Generally, a construction machine often stores a battery in an engine room or a frame cover.
In recent years, construction machines in which batteries are arranged on the floor of a cab have been known. For example, as shown in FIGS. 4 and 5,
A box-shaped bracket 3 is fixed to the floor 2 of the operator's cab 1, a seat 4 is mounted on the bracket 3, and a battery B is arranged on the floor 2 below the seat 4. An opening 6 for inserting and removing the battery B is provided on the front surface of the bracket 3, and a cover 7 is fastened to this opening 6 with bolts 8.
Battery B was covered. The cover 7 is provided with windows 9 such as small holes and slits for checking the liquid level of the battery B.

[0003]

When the battery B is disposed below the seat 4, generally, a sufficient space S between the upper plate of the bracket 3 and the battery B cannot be obtained. Therefore, when attaching or detaching the battery B, first, the bolt 8 is loosened to remove the cover 7, and the operator must drag the battery B in and out of the opening 6 in an unreasonable posture, and a greater force is applied. Needed.

Further, since the cover 7 is provided with the window 9, there is a risk that gas generated by evaporation of the battery fluid flows out of the window 9 and fills the cab 1. Therefore, when arranging the battery in the construction machine, there is a technical problem to be solved in order to minimize the storage space, facilitate the battery attaching / detaching operation, and facilitate the maintenance of the battery. Therefore, an object of the present invention is to solve this problem.

[0005]

SUMMARY OF THE INVENTION The present invention has been proposed to achieve the above object. A seat mounting bracket is fixed to a floor of a driver's cab, and a seat is mounted on an upper portion of the bracket. In a construction machine that arranges a battery on the floor below the seat, a battery stand is provided on the floor, the battery is arranged on the battery stand, and the battery stand is formed so as to be able to be pulled out to the front or side of the seat, Still another object of the present invention is to provide a battery storage device of a construction machine in which a battery is covered by providing an openable / closable door on a front portion or a side portion of the bracket.

[0006]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows a hydraulic excavator 10 in which an upper revolving structure 12 is mounted on a lower traveling structure 11 so as to be capable of revolving horizontally and in all directions, and a work attachment 13 is mounted on a front portion of the upper revolving structure 12. Further, an operator cab 21 is provided in the upper revolving unit 12.

FIG. 2 shows the inside of the cab 21 and the floor 2
2, a box-shaped bracket 23 is fixedly mounted, and a sheet 24 is mounted on an upper portion thereof. On the floor 22 below the seat 24, a battery stand 25 is provided.
Place. As will be described later, a rail is provided on the lower surface of the battery table 25 in the front-rear direction, and the battery table 25 is placed on the floor 22 in front of the seat 24 while the battery B is arranged on the upper surface of the battery table 25. It is formed so that it can be pulled out.

An opening 26 for taking in and out the battery B is provided on the front surface of the bracket 23, and a door 27 which can be opened and closed is attached to the opening 26. Normally, by closing the door 27, the battery B is covered and stored in the bracket 23, so that the danger that the gas generated by the evaporation of the battery liquid fills the cab 21 can be prevented.

Here, when removing the battery B during maintenance, as shown in FIG.
Is opened, and the battery stand 25 is pulled out to the front of the seat 24. A rail 28 is laid on the floor 22 on the lower surface of the battery stand 25, and the battery stand 25 is slidable back and forth along the rail 28, so that the battery stand 25 can be moved forward with a light operating force. Can be withdrawn.

Although not shown, the rail 28 is laid in the left and right direction of the floor 22 so that the battery stand 25 can be slid to the side, and an opening 26 is provided on one of the left and right side surfaces of the bracket 23. Is also good. Also in the case of such a configuration, the door 27 is opened at the time of maintenance, and the battery stand 25 is pulled out to the side of the seat 24.

[0011] Thus, the battery B is exposed to the front or side of the seat 24, so that the liquid level of the battery B can be easily checked, and the battery B can be detached and attached in a safe posture.

The present invention can be variously modified without departing from the spirit of the present invention, and the present invention naturally extends to the modified ones.

[0013]

As described above, according to the present invention, a battery stand is provided on the floor below the seat in the operator's cab, the batteries are arranged, and the battery stand is formed so as to be drawn out along the floor surface. It is no longer necessary to put a hand in a narrow place and lift the battery in an unreasonable posture, and it is possible to easily attach and detach the battery in a safe posture.

Further, since the battery accommodated in the bracket is covered by the door, it is possible to prevent the gas generated by evaporation of the battery fluid from filling the cab. Thus, the maintainability and the safety can be improved while keeping the cost low.
