[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover mounted on the upper side of an upper swing body of a small shovel.

[0002]

2. Description of the Related Art FIG. 5 is a perspective view of a conventional small shovel. In the drawing, 1 is a lower traveling body of a small shovel, 2 is an upper revolving superstructure, 3 is a driver's seat, 4 is a hydraulic oil tank,
5 is a fuel tank, 6 is a step portion, 7 is a non-slip pattern on the upper surface of the step portion 6, 8 is a battery box below the step portion 6, 9 is a work attachment, and 0 is an upper revolving unit 2.
, R ₁ is the rear end turning radius of the upper turning body 2. In the small excavator shown in FIG. 5, a driver's seat 3 is provided on the upper revolving unit 2, and a hydraulic oil tank 4 is provided beside the driver's seat 3.
A step portion 6 is formed on the upper surface of the upper revolving structure 2 so as to be disposed in the fuel tank 5 or the like, and to be able to move up and down to the driver's seat 3 from the side in front of the tanks.

[0003]

Since the juxtaposed hydraulic oil tank 4 and the fuel tank 5 is a small excavator of the prior art in FIG. 5 [devised is to solve the above in the longitudinal direction, the rear end turning radius R ₁ of the upper rotating body 2 is substantially larger Is inconvenient for work. FIG.
FIG. 3 is a plan view of a main part of the small shovel, which is considered in order to reduce a rear end turning radius of the upper turning body 10. In the figure,
11 hydraulic oil tank, 12 a fuel tank, 0 'turning center of the upper rotating body 10, R ₂ is a rear end turning radius of the upper rotating body 10. FIG. 7 is a rear view as viewed from A in FIG.
FIG. 8 is a diagram viewed from BB in FIG. In the figure,
13 is a flange cover for flushing the hydraulic oil tank 11, 14 is a level gauge, 15 is a drain filter, 16
Denotes a level sensor mounting portion of the fuel tank 12. So, as shown in FIG. 6, since the hydraulic oil tank 11 and the fuel tank 12 on the driver's side and right and left directions juxtaposed, could be set to a smaller size the rear turning radius R _2. However, FIG.
This is inconvenient because the accessory devices shown in (1) are exposed on the front sides of both tanks. Further, as shown in FIG. 6, when checking the battery below the step portion 6, the bolts (indicated by the symbol "a") which are tightening the step portion 6 are loosened and removed, so that the trouble is troublesome. An object of the present invention is to provide a cover for a small shovel that can solve the above problems.

[0004]

According to the present invention, an L-shaped cover is provided which covers the front side of tanks on the side of the driver's seat, and which also serves as a step portion over the upper surface of the upper revolving structure. The front part was hinged to the front part of the upper revolving body so as to be freely rotatable. The material of the cover was formed of a non-metallic member such as a resin material.

[0005]

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 left side view of the small shovel equipped with the cover 17 of the present invention. In the figure, 18 is an upper revolving structure, 19 is a driver's seat, and 20 is a tank such as a hydraulic oil tank and a fuel tank. FIG. 2 is a right side cutaway view of a main part of the upper swing body 18 in FIG. FIG. 3 shows C in FIG.
FIG. In the figure, reference numeral 21 denotes a bracket for attaching a hinge fitting fixedly provided inside a front portion of the upper revolving unit 18, 22 denotes a hinge fitting, 23 denotes a step portion of the cover 17, and 24 denotes a reinforcement formed inside the cover 17. rib,
25 is a lock fitting such as a key cylinder for locking the cover 17 to the tank 20 side, 26 is a locking bracket provided fixed to the tank 20 and engaged with the lock fitting 25, 2
Reference numeral 7 denotes a battery box at the front of the upper swing body 18.
FIG. 4 is a front view showing the cover 17 as viewed from D in FIG. In the figure, reference numeral 28 denotes a finger hook used to tilt and rotate the cover 17 forward.

Next, the structure of the cover 17 of the present invention is shown in FIGS.
Referring to FIG. In the present invention, the L-shaped cover 1 covers the front surface of the tank 20 on the side of the driver's seat 19 and also serves as the step portion 23 over the upper surface of the upper revolving unit 18.
7, and the front part of the cover 17 is hinged using a hinge fitting 22 so as to be rotatable with respect to the front part of the upper rotating body 18. The cover 17 is made of a non-metallic material such as a resin material such as glass fiber reinforced plastic (FRP).

Next, the operation of the cover 17 of the present invention will be described. As shown in FIG. 3, when the latch 25 on the cover 17 is engaged with the bracket 26 of the tank 20, the cover 17 is locked and fixed to the upper swing body 18. Therefore, the driver can step up and down on the driver's seat 19 by stepping on the step portion 23 of the cover 17. With it,
Since the cover 17 covers the front side of the tank 20, the attached devices arranged on the front side of the tank 20 are not seen, and the appearance is good. Next, when inspecting the accessory device on the front surface of the tank 20 or the inside of the battery box 27, the engagement operation of the locking fitting 25 is released. Then, the finger is hooked on the finger hooking portion 28 on the upper portion of the cover 17 to rotate the cover 17 forward (in the direction of arrow B shown in FIG. 2). Cover 17
Is rotated about the axis of the hinge fitting 22 as a rotation center, and is tilted to the position of the imaginary line C. As a result, the front surface of the tank 20 and the upper surface of the battery box 27 are opened, so that required inspection and repair can be performed. When the inspection, repair, or the like is completed, the cover 17 can be fixed to the upper swing body 18 again by performing an operation reverse to the above-described opening operation. Further, since the material of the cover 17 of the present invention is made of a resin material, its weight is light, and the tilting operation of the cover 17 can be performed easily and in a short time. Further, since the configuration can be made with the minimum number of parts, the manufacturing cost can be reduced.

[0008]

Various small shovels with a small rear end turning radius have been considered in the prior art, but they have been inconvenient because accessories such as tanks arranged on the driver's seat side are exposed on the front side. In addition, a step portion for elevating and lowering is provided on the upper surface of the upper revolving structure in front of the tanks, and a battery box is provided below the step portion. Therefore, when checking the battery, the above-mentioned step portion had to be removed, which was troublesome.
However, when the cover of the present invention is fixed to the upper revolving unit, the user can step up and down to the driver's seat by stepping on the step portion of the cover. At the same time, since the cover covers the front side of the tanks, the attached devices arranged on the front of the tanks are not seen, and the appearance is good. Also, when inspecting an accessory device on the front of the tanks or the inside of the battery box, the locking fitting of the cover is released and the cover is tilted and rotated forward. This opens the front surfaces of the tanks and the upper surface of the battery box, so that necessary inspections and repairs can be easily performed. In addition, since the cover of the present invention is made of a resin material, the cover is light in weight, and the cover can be tilted and rotated easily and quickly. Further, since the configuration can be made with the minimum number of parts, the manufacturing cost can be reduced.
