FIG. 1 is a plan view of an embodiment of an upper revolving unit according to the present invention, and FIG. 2 is a plan view of a fuel tank having an upper revolving unit according to a second embodiment of the present invention. FIG. 3 is a plan view of the embodiment, and FIG. 3 is a side view of FIG.

The present invention will be described below with reference to an embodiment shown in FIGS. Claim 1 of the present invention is to dispose a hydraulic device 2 such as an operation valve and a hydraulic oil tank 3 in the order of a right front portion of an upper revolving structure 1 such as a power shovel, and a driver's cab 4 and a driver's seat in the driver's cab 4 on the left. 5, a fuel tank 7 is arranged on the bottom surface of the revolving frame 6 below, and the fuel tank 7 is made of a resin which is asymmetrical to the left and right, and most of the fuel tank 7 is rotated in the upper direction.
It is housed in a revolving body frame (hereinafter referred to as a revo frame ) 6, a part of which protrudes above the floor frame 8, and has a driver seat 5.
It is provided so as to approach the lower part of.

As shown in FIGS. 1 to 3, the upper revolving unit 1 of the power shovel has a boom (not shown) at the center thereof.
A base end of a working machine composed of an arm, a bucket, and the like is mounted so as to be able to move up and down via a revoframe 6 toward the front, and on the right side, in order from the front, a battery 9, a hydraulic device 2 such as an operation valve, and the like. A hydraulic oil tank 3 is provided. Also,
A driver's cab 4 is disposed on the left side, and a fuel tank 7 is disposed on a bottom surface of a revo frame 6 below a driver's seat 5 in the driver's cab 4. Further, an engine room 10 is disposed at a rear portion of the upper revolving structure 1, and a counterweight 11 is provided at a rear end. With such an arrangement, the piping connecting the hydraulic equipment 2 to the hydraulic oil tank 3 and the piping for the working machine can be shortened, and a thin hydraulic hose for pilot pressure control, Only cables for use. R in FIG. 1 indicates the turning radius at the turning center.

FIGS. 2 and 3 show details of the fuel tank 7 according to the present invention. The fuel tank 7 is provided on the bottom surface of the revo-frame 6 below the cab 4, and the inside of the revo-frame 6 is shown in FIG.
Working machine lever-1 provided on the upper surface of the floor as shown in FIG.
In the present invention, the material is made of resin and has a free size, so that the left and right sides are asymmetrical, so that it can be accommodated in a complicated space avoiding these. It has an odd shape as shown in the figure. Most of the size 7a is accommodated in the revoframe 6, but a portion 7b below the driver's seat 5 projects from the upper surface of the floor frame 8 and has a height close to the driver's seat 5. The fuel tank 7 is placed on support members 13 and 14 fixed to the bottom surface of the revoframe 6, and the upper surface of the band 1 is connected to the support members 13 and 14.
It is tightened at a plurality of locations by 5,16. In the figure, 1
7 is a supply port to the engine.

Next, the operation will be described. When the hydraulic equipment system needs to be inspected due to a failure or the like, the hydraulic equipment 2 including the operation valve and the hydraulic oil tank 3 are arranged above the upper revolving unit 1 and are exposed outside. Maintenance becomes very easy, and thus downtime in working hours is reduced. Further, the installation space of the fuel tank 7 is limited due to the external arrangement of the hydraulic equipment system, but the fuel tank 7 can be accommodated in the complicated space of the revoframe 6, so that there is no possibility of damage due to contact with the outside. In addition, the insufficient capacity can be ensured by increasing the height to a position close to the lower part of the seat of the driver's seat 5, so that the capacity can be ensured.
6, the movement in the front, rear, left and right and up and down directions is prevented.

[0012]

[Effect of the invention] As described above , the first invention of the present application is
According to the report, the fuel tank is
There is no danger of damage due to contact with the outside
The shortage of capacity is partly under the driver's seat.
The capacity is secured by raising to the position close to
Wear. According to the second invention of the present application, the fuel tank is made of resin.
The degree of freedom of the shape can be obtained.
A shape that fits the sharp space becomes possible. for that reason,
Shapes that could not be obtained with conventional steel plates can be manufactured , and the layout of the devices can be facilitated.
