Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an exterior device for a construction machine such as a power shovel.

(Prior Art) In a conventional construction machine such as a power shovel, as shown in FIG. 3, an upper revolving structure b is rotatably provided on a lower traveling structure a which is capable of traveling by a band, and in front of the upper revolving structure b. It has a structure in which a working machine c is attached to the section.

Further, the upper swing body b has a floor plate d, a lever stand cover e,
Exterior parts such as engine cover f and hydraulic oil tank g are attached.

(Problems to be solved by the invention) In the above-mentioned conventional construction machine, since most of the exterior parts attached to the upper swing body are manufactured by sheet metal working,
Molds are expensive for exterior parts with complicated shapes, so there was a problem that the price of exterior parts made the construction machinery more expensive, especially for construction machines with low production volume.

Further, since an outer frame h is provided around the upper swing body b as shown in FIG. 4 to improve the appearance, there is a problem that the price of the upper swing body b becomes high.

The present invention has been made for the purpose of improving the above problems, and an object of the present invention is to provide a vehicle body device for a construction machine, in which the cost is reduced by reducing the number of exterior parts.

(Means and Actions for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides an upper revolving structure on a lower traveling structure so that the upper revolving structure is freely rotatable, and a working machine and a rear part are provided at the front part of the upper revolving structure. In a construction machine in which an engine room is provided, a floor plate covering the front upper surface of the upper swing body, a lever stand provided on the floor plate, and an outer frame provided around the upper swing body are integrally molded with fiber-reinforced resin. By forming the exterior body by doing so, and attaching this exterior body to the upper swing body in a detachable manner, it is possible to integrally form the exterior parts that were conventionally manufactured separately, and at the same time reduce the number of parts of the construction machine. An exterior device is provided.

(Embodiment) An embodiment of the present invention will be described in detail with reference to the drawings.

In the figure, reference numeral 1 is a construction machine such as a power shovel, and an upper revolving structure 4 is rotatably provided on a lower traveling structure 2 which is capable of traveling by a cover band 3.

A working machine 5 is provided in the front part of the upper revolving structure 4, and an engine room 6 accommodating an engine (not shown) is provided in the rear part of the upper revolving structure 4.
Is installed.

The exterior body 7 has a structure shown in FIG. 2 in which a conventional floor board, a lever stand, and an outer frame provided around the upper swing body 4 are integrated.

That is, the exterior body 7 is made entirely of fiber reinforced resin (FRP) by the floor plate 7a, the outer frame 7b formed on the front side and both side edges of the floor plate 7a, and the lever stand 7c protruding from the front upper surface of the floor plate 7a. It is integrally molded.

Further, in order to facilitate the attachment to the upper swing body 4, it is divided into two parts from the central part to the left and right.

On the other hand, the exterior body 7 is detachably attached to the upper swing body 4 and various operation levers 8 project from the lever stand 7c in order to facilitate inspection and maintenance of linkages and various devices provided under the floor. Has been done.

A driver's seat 9 is mounted on the upper part of the engine compartment 6, and a hydraulic oil tank 10 and a bumper 11 are mounted on both sides and the rear part.

(Effects of the Invention) As described in detail above, this invention enables exterior parts such as outer frames, floor boards, and lever stands that were conventionally manufactured as separate parts to be integrally formed of fiber reinforced resin and attached to the upper revolving structure. As a result, compared to the case where the exterior parts are manufactured separately, the cost of the parts can be significantly reduced and the number of parts is reduced, so that the number of assembling steps can be reduced.

In addition, since a complicated shape can be easily molded with resin, it can be provided at a lower cost than when sheet metal processing was performed.
