DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a cross-sectional view of a main part near a counterweight 2a having a tool box structure according to an embodiment of the present invention. 7a is a center frame of the upper swing body 1a, 5a is an engine, 6a is an engine room, 8a is an engine hood, 9 is a tool box holding bracket provided on the front portion of the counterweight 2a, 10 is a tool box, 11 is a tool box 10 Reference numeral 12 denotes a cover plate of the tool box 10. FIG.
It is the principal part top view of the upper revolving superstructure 1a seen from -A. In the figure, reference numeral 13 denotes a bolt for fastening the mounting board portion 11 of the tool box 10 to the counterweight 2a.

The tool box structure shown in FIGS. 1 and 2 and its operation will be described. In the tool box structure of the present embodiment, the tool box 10 is detachably mounted on the front upper portion of the counterweight 2a. In the upper revolving unit 1a, the engine 5a is arranged close to the front side of the counterweight 2a.
The engine compartment 6 may be mounted for reasons such as the mounting of the engine 5a and the inspection and repair of the engine 5a and its peripheral devices.
There is some space in a. Therefore, the tool box 10
When attaching to the counterweight 2a, the tool box 1
0 at the lower edge of the mounting substrate portion 11
And the mounting substrate 11 is fastened and fixed to the counterweight 2a with bolts 13. Since various tool members can be safely stored in the tool box 10, it is possible to conveniently and effectively use space. When a heavy tool member or a heavy block member (select an appropriate block member) is put in the tool box 10,
Since they work as a weight increase counterweight,
The stability of the hydraulic excavator can be improved. Further, if the tool box 10 is obstructed when performing inspection and repair of the engine 5a and its peripheral devices, the bolts 13 may be loosened to remove the tool box 10. In the embodiment shown in FIGS. 1 and 2, the cover 12 is provided on the tool plate 10, but since the engine bonnet 8a is present, the cover 12 does not always need to be attached.

Next, FIG. 3 is a sectional view of a main part near a counterweight 2b having a tool box structure according to another embodiment of the present invention. 7b is the center frame of the upper swing body 1b, 5b
Is an engine, 6b is an engine compartment, 8b is an engine bonnet, 14 is a cutout recess formed from the front surface to the lower surface of the counterweight 2b, 15 is a tool box, and 16 is detachably attached to the lower side of the center frame 7b. Bottom plate. FIG. 4 is a diagram viewed from BB in FIG.

The tool box structure shown in FIGS. 3 and 4 and its operation will be described. In the tool box structure of the present embodiment, the notch recess 14 is formed from the front surface to the lower surface of the counterweight 2b, and the tool box 15 is mounted in the space of the notch recess 14. Thus, when removing or storing the tool members in the tool box 15, the lower plate 16 can be opened and the tool members can be removed from the lower surface side of the upper swing body 1b. That is, since the driver or the operator can put the tool member in and out of the tool box 15 provided on the ground at a low position of the counterweight 2b, the operation for putting in and taking out is simple and convenient.

Next, FIG. 5 is a side view of a small excavator having a tool box structure of still another counterweight 2C according to the present invention. In the figure, 17 is a cover covering the rear part of the upper swing body 1C, 18 is a cab, 19 is a lower traveling body,
Reference numeral 20 denotes a work attachment. FIG. 6 is a partially cutaway side view of the rear part of the upper swing body 1C in FIG. In the figure, 7C is the center frame of the upper swing body 1C, 5C
Denotes an engine, 6C denotes an engine room, 21 denotes a tool box, and 22 denotes a bolt for removably fastening the tool box 21 to the upper surface of the counterweight 2C.

The tool box structure shown in FIGS. 5 and 6 and its operation will be described. In the tool box structure of the present embodiment, the counter weight (2
C) The tool box 21 was disposed inside the cover 17 on the upper side. The function and function of the tool box structure according to the third aspect are the same as those of the tool box structure according to the first aspect. However, in the tool box structure according to the third aspect, the mounting height of the counterweight 2C is low. Alternatively, the operator can take the tool member in and out of the tool box 21 or attach and detach the tool box 21 on the ground.

[0011]

According to the counterweight tool box structure of the present invention, when heavy tool members or block members are put into the above-mentioned tool box, they act as additional counterweights, thereby improving the stability of the construction machine. Can be done. In addition, a tool box is provided using the space for engine inspection on the side of the counterweight attached to the upper revolving structure that is in contact with the engine room, so that various tool members can be safely placed inside the tool box. It can be stored, convenient and effective use of space.
