[0003]

Conventionally, many booms of hydraulic excavators are equipped with a work light for illuminating a lower front portion, and most of them are disposed on a side surface of the boom. However, the machine is often used in a small work environment, and the operator may pass the work light during operation and contact the work light, or the work light may be damaged by a falling object hitting the work light. . The purpose of the present invention is to solve the above problems.

[0004]

[MEANS FOR SOLVING THE PROBLEMS] In the front of a construction machine
Mounted boom and oil disposed on the side of the boom
Pressure pipe, and a cover that covers at least a part of the pipe,
A work light attached to the boom, wherein the work light is
At least a part was covered by the cover. Furthermore,
The work light is substantially covered by the cover.
A portion of the cover corresponding to a front portion of the work light;
Then, a window hole for irradiation was opened.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a side view of a hydraulic excavator equipped with the lighting device of the present embodiment . In the figure, the same reference numerals are given to components using the same components as the conventional technology. 1
Reference numeral 2 denotes an upper swing body of the excavator, and 13 denotes a cover attached to a side surface of the boom 2. FIG. 2 is a detailed cutaway view of a portion C in FIG. FIG. 3 is a front view of a main part viewed from DD in FIG. Reference numeral 14 denotes a bracket for mounting the work light 7.

Next, the structure of a lighting device according to an embodiment of the present invention will be described with reference to FIGS. In the lighting device of the present embodiment , a hydraulic pipe 11 is provided on the side surface of the boom 2.
Also, the bracket 14 is attached to the side of the boom 2 with the bolt 11.
The work light 7 is disposed above the bracket 14. The cover 13 is fastened to the side surface of the boom 2 with bolts 9 so as to cover both the hydraulic pipe 11 and the work lamp 7.

Next, the operation of the lighting device according to the embodiment of the present invention will be described. In this embodiment , the working light 7 and the hydraulic pipe 8
Are covered by the cover 13, so that the front surface, the upper surface, and the side surface of the work light 7 are all surrounded by the cover 13. Thus, when the excavator performs work, even if an obstacle comes into contact with the cover 13, the work light 7 does not come into contact with the cover 13. Therefore, there is no possibility that the work light 7 comes into direct contact with an external object or an accident that the falling object is directly hit.

[0008]

In the lighting device of the prior art, the working lamp is mounted on the side surface of the boom in a substantially bare state. Therefore, when working in a narrow site, the operator often touches the work light with an object, or the work light is often damaged by a falling object. However, in the lighting device of the present invention, the work light can be prevented from being damaged by covering the work light with the cover. In addition, the appearance is improved because the work light is no longer visible. Therefore, in the lighting device of the present invention, the maintenance property and the appearance of the work light can be improved.
