Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a hood of an engine room in a power shovel.

(Prior Art) Conventionally, an engine of a power shovel has been installed in an upper revolving structure, but the engine room serves as an engine sound insulation, an engine hood, a support for a canopy, and the like.
The structure of the cover of the engine compartment is formed so as to surround the upper part of the engine and the periphery excluding the engine hood on one side, and only one side is formed by the hood.

(Problems to be solved by the invention) When the engine cover has the above-described structure, as shown in FIG. 4, the canopy 21 swings if it has no rigidity to support the engine hood and the canopy 21, A thick plate is used for the entire cover member 22 in order to provide rigidity in the vertical direction, and reinforcing ribs are also required, which complicates the structure.

Therefore, there are drawbacks that productivity is deteriorated and cost is increased.

In view of this, the present invention provides a hood for an engine compartment that is not attached to a thick plate as a cover member and has rigidity to a support of a canopy and is attached to an engine compartment that does not shake. It was made with the aim of eliminating the drawbacks it possesses.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides an engine room such as a power shovel having at least one frame having a horizontal surface higher than that of the engine and formed with legs downward, A canopy mounting base having a canopy pole mounting surface on the upper surface while maintaining a constant space in the frame, a beam member connecting the frame and the canopy mounting base, and an upper end of the beam member. To form a skeleton with at least one stay whose lower part is formed into a leg, and the front part is placed on the canopy pole mounting surface and the horizontal surface of the frame, and the upper part and the periphery of the engine excluding the stay side are In a bendable cover member, the rear portion is provided on the stay while covering the stay side via a hinge provided on the beam member. It is characterized by being a hood that is held in an open / closed state by a support rod that can be raised and lowered freely.

(Operation) With the above configuration, the hood can be stably attached to the skeleton even if the appearance of the front portion of the engine compartment is a thin plate.

(Embodiment) Hereinafter, the present invention will be described with reference to an embodiment shown in FIGS. 1 and 3.

The present invention includes an engine room 1 such as a power shovel, at least one frame 3 having a horizontal surface 3a higher than the engine 2 and a leg 3b formed below, and the frame 3 with a fixed interval. A canopy mount 4 having an upper surface as a canopy pole mounting surface 4a and legs 4b having the same height as the frame 3, a beam member 5 connecting the frame 3 and the canopy mount 4, and a beam member 5 A skeleton is constituted by at least one stay 6 having an upper end 6a fixed and a lower part formed on a leg 6b.
4a and a frame horizontal surface 3a, which is a cover member 7 which can be bent on the upper part and the periphery of the engine 2 except for the stay 6 side, the rear part of which is provided with a hinge 8 provided on the beam member 5 A hood 10 is provided which covers the stay 6 side and is held in an open / closed state by a support rod 9 provided on the stay 6 and which can be raised and lowered.

The engine 2 is mounted on the floor 12 at the rear of the revolving frame 11 in the left-right direction, and similarly, the frame 3 and the canopy mount 4 are also provided on the floor 12 under the legs 3b and 4b, respectively. It is fixed by.

The upper surface of the canopy mounting base 4 is formed on a canopy pole mounting surface 4a, and a plurality of bolt holes 14 for mounting a canopy pole (not shown) are provided on this surface 4a.

The beam member 5 is fixed to the horizontal surface 3a of the frame 3 and the pole mounting surface 4a of the canopy mounting base 4 in the lateral direction of the vehicle body.

Also, two stays 6 are used in this embodiment, the upper end 6a of the beam member 5 is fixed, and the lower part of the stay 6 is convexly curved rearward so as not to interfere with the engine 2.
6b, the lower end of which is fixed to a position slightly higher than the floor surface 12 by the tightening means 13 like the frame 3.

The cover member 7 is made of plastic to obtain the R part,
A thin plate material that can be integrally processed by pressing, welding, etc. is used, and a hole 7a for inserting a bolt is provided in a portion overlapping the canopy pole mounting surface 4a.

The cover member 7 covers the one side portion of the engine 2 located on the front side of the revolving frame 11, the front and rear portions and the upper portion excluding the stay 6, and the upper surfaces of the frame 3 and the canopy mount 4. The lower end portion is fixed to a position slightly higher than the floor surface 12 by tightening means 14 such as bolts.

The beam member 5 is provided with a hinge 8 that allows the hood 10 to be opened and closed at the upper portion, so that the hood 10 covers the upper portion of the stay 6.

Further, the stay 6 is provided with a support bar 9 which can be raised and lowered by rotation near the upper end 6a.

Therefore, when the hood 10 is opened upward with the hinge 8 as a fulcrum and the support rod 9 is rotated upward as shown by an arrow, the hood 10 is held in an open state by the tip of the support rod 9.

When the support rod 9 is rotated downward, the hood 10 is not supported and is rotated downward, so that the engine compartment 1 is closed.

It should be noted that the present invention has been described by providing one frame in the embodiment, but it goes without saying that two frames may be used. Further, the frame may have a gate shape.

FIG. 3 shows a cross-sectional view of an application example of the hood 10 in which the radiator 16 portion in the engine compartment 1 composed of the cover member 7 and the hood 10 is surrounded by the sound absorbing material 17, and the inside and outside of the stay 6 also absorbs noise. Material 17 is used. By arranging the sound absorbing material 17 in this way, the hood 10 can separate the front of the radiator 16 and the engine 2 main body side together with the stay 6.

(Effects of the Invention) As described above, the present invention provides an engine room such as a power shovel having at least one frame having a horizontal surface higher than the engine and having legs formed on the lower side thereof, and a fixed interval between the frames. A canopy mount that holds the upper surface of the canopy pole and has the same height as the frame, a beam member that connects the frame and the canopy mount, and an upper end of the beam member that is fixed to the lower part. The frame is composed of at least one stay formed on the leg, and the front part is
A cover member that is placed on the canopy pole mounting surface and the horizontal surface of the frame and that can bend the upper part and the periphery of the engine except the stay side, wherein the rear part is on the stay side via a hinge provided on the beam member. In addition to covering the hood, the hood is held in an open / closed state by the up and down support rods provided on the stay, so it can be applied to thin cover members, and the hinges can be attached securely. In this case, the hood can be held in the upper position by the support rod.
