AI Technical Summary

Benefits of technology

The present invention aims to provide a construction machine that can easily mount / demount the counterweight, even when there are articles left in the article accommodating room. This is achieved by arranging a placing member on the vehicle body frame side, allowing for the placement of articles without the need for the counterweight to be disconnected from the power source or piping. Additionally, the invention provides a partition member to protect the article room from heat and oil leakage, as well as a lid member to protect the articles from external factors. The invention offers a more convenient and efficient way to transport and use construction machines.

Problems solved by technology

However, since the concave space part is provided on the upper side of the counterweight, in a case where the article that is connected via an electric wire such as, for example, a battery has been accommodated, there is such a problem that the electric wire leading to the battery should be disconnected when mounting / demounting the counterweight and labor is required for work of mounting / demounting the counterweight.

first embodiment

[0038]FIG. 1 to FIG. 8 show the construction machine according to the present invention.

[0039]In FIG. 1, designated at 1 is a hydraulic excavator as the construction machine used for earth and sand excavating work and so forth. This hydraulic excavator 1 is configured by an automotive crawler-type lower traveling structure 2, an upper revolving structure 3 that is revolvably loaded on the lower traveling structure 2 and constitutes a vehicle body together with the lower traveling structure 2, and a working mechanism 4 that is tiltably provided on the front side of the upper revolving structure 3.

[0040]The working mechanism 4 is provided with a boom 4A, an arm 4B and a bucket 4C and these are rotationally moved by a boom cylinder 4D, an arm cylinder 4E and a bucket cylinder 4F. The base end of the boom 4A is rotatably connected to boom mounting portions 8A and 9A of left and right vertical plates 8 and 9 of a revolving frame 5, which will be described later.

[0041]The upper revolving ...

Abstract

A left weight mounting part (16) and a right weight mounting part (17) are provided with rear ends of a left vertical plate (8) and a right vertical plate (9) of a main frame (6), and a placing plate (24) adapted to place a battery (29) thereon is provided between the left weight mounting part (16) and the right weight mounting part (17). An accommodating groove (25G) is provided in a counterweight (25) by notching, in a front-rear direction, a part that faces the placing plate (24) in an up-down direction. A space (26A) formed by the placing plate (24) and the accommodating groove (25G) can be configured as an article accommodating room (26) that accommodates the battery (29).

Description

TECHNICAL FIELD[0001]The present invention relates to a construction machine such as, for example, a hydraulic excavator or the like that a counterweight has been mounted to a rear end of a vehicle body frame.BACKGROUND ART[0002]In general, the hydraulic excavator that is a representative example of the construction machine is configured by an automotive lower traveling structure, an upper revolving structure revolvably loaded on the lower traveling structure and a working mechanism tiltably provided on the front side of the upper revolving structure.[0003]The upper revolving structure is configured by including a revolving frame that forms a support structure, a counterweight mounted to the rear end of the revolving frame in order to balance weight with the working mechanism, and an engine located on the front side of the counterweight and loaded on the aforementioned revolving frame.[0004]The whole of the hydraulic excavator is formed small so as to reduce a working range when rev...
