DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings. In the figure, reference numeral 1 denotes a small hydraulic excavator. The hydraulic excavator 1 is provided on a crawler type lower traveling body 2, an upper revolving body 3 that is pivotably provided on the lower traveling body 2, and a lower traveling body 2. The dozer 4 is configured to include a bucket 5 provided on the upper swing body 3, and the upper swing body 3 further includes various member devices such as a driver's seat 6 and a canopy 7, and further includes a front end of the swing body frame 8. A swing post 5b that supports the first boom 5a so as to be swingable up and down is pivotally supported on the post support portion 8a that protrudes to the left and right, and the bucket 5 is offset left and right based on the expansion and contraction of the offset cylinder 8b. However, since these are the same as the conventional configuration, the details thereof are omitted.
[0006]
The upper revolving unit 3 is provided with an operation lever 8c positioned in front of the driver's seat 6 so as to be planted from the revolving unit floor 8. Further, a front portion is provided at the front side thereof, that is, at the front end of the revolving unit frame 8. Handrails (handrails) 9 are provided, and a side handrail 10 is provided on the left side of the driver's seat 6, and these handrails correspond to the bowl-shaped body of the present invention in the present embodiment. To do. The front handrail 9 has a pair of left and right bases 11 fixed to the revolving body frame 8 and a lower frame 12a supported by the base 11, and the left end side of the lower frame 12a is slightly smaller than the upper frame 12b. The main frame body 12 is composed of a rod-like body (or a cylindrical body) that is bent so as to have a substantially trapezoidal shape in a long front view, but it is more than the upper side frame 12b of the lower side frame 12a. The long portion 12c is bent obliquely rearward along the front left edge of the revolving body frame 8, and the left side frame 12d of the main frame body 12 is positioned at the left end of the upper side frame 12b and obliquely rearward thereof. It is inclined to connect the left end of the lower frame 12a. Further, the main frame body 12 is provided with an intermediate frame 12f that is located between the upper and lower frames 12b and 12a and connects the left frame 12d and the right frame 12e. The part is also bent diagonally backward.
[0007]
On the other hand, the handrail 10 on the side is formed of a rod or a cylindrical body, and the handrail 10 extends rearward from the front frame 10a that is long in the vertical direction and the upper end of the front frame 10a. An upper frame 10b, a rear frame 10c bent rightward from the rear end of the upper frame 10b, and an intermediate frame 10d extending downward from an intermediate portion of the upper frame 10b. It is configured.
[0008]
Reference numeral 13 denotes a housing, and the housing 13 includes a housing body (lamp) 14 having an irradiation function and a cover body 15 that encloses the housing body 14. The heel body 14 has a substantially rectangular shape, and both sides of the substantially 14-shaped handle 14a are fastened to the left and right side surfaces thereof, but the grip 14 is fastened in a posture that is inclined rearward and upward. Yes.
On the other hand, the cover body 15 is formed by bending a plate-like body into a substantially U shape in a side view so as to enclose the bag main body 14, and at the corner portion between the upper surface portion 15a and the rear surface portion (rear surface portion) 15b. An inclined surface portion 15c is formed, and the handle 14a is fixed by a bolt (fixing tool) 16 penetrating from the outside of the inclined surface portion 15c, thereby fixing the rod main body 14 to the cover body 15. . Further, the upper surface portion 15a of the cover body 15 is formed with a pair of two long holes 15d that are long in the front-rear direction and arranged in a line in the front-rear direction.
[0009]
On the other hand, reference numeral 17 denotes a mounting bracket having a substantially inverted U-shape, and screws are engraved at both leg ends of the mounting bracket 17. For example, the mounting bracket 17 allows the both leg portions to pass through the front and rear long holes 15d in a loosely fitting manner in a state of being fitted from the upper side to the left position of the intermediate frame 12f in the front handrail 9, and the penetrating tip portion. Then, the cover body 15 can be fixedly attached to the intermediate frame 12f by tightening with the nut 17a, whereby the housing 13 can be fixed.
[0010]
In addition, when the casing 13 is fastened as described above, the vertical and horizontal irradiation angles of the casing 13 can be easily adjusted when the nut is tightened. In other words, if the nut 17a is loosely engaged with the screw portion of the mounting bracket 17, the cover body 15 can be adjusted to swing up and down around the intermediate frame 12f as an axis, and further penetrates the elongated hole 15d. By swinging the left and right by the amount of play of both legs, the nut 13 can be attached and fixed in the state of facing the desired irradiation direction by tightening the nut with the vertical and horizontal adjustments made in this way. .
[0011]
In the structure as described above, the housing 13 is attached to any of the front and side handrails 9 and 10 and to any position of these handrails 9 and 10 in any orientation. For this reason, the housing can be attached according to the work contents and the preference of the worker. And since the irradiation direction of the housing | casing 13 can be adjusted freely right and left and up and down, it can adjust to a more preferable irradiation direction.
[0012]
The casing 13 that can be attached to an arbitrary position as described above is composed of a casing main body 14 having an irradiation function and a cover body 15 including the same, and the cover body 15 is attached to the handrail 9 or 10. Therefore, not only the cover body 15 is protected by the cover body 15, but there is also no need to make the cover body 14 itself a special shape and a mounting portion formed, and a general-purpose one is adopted. Installation will be possible. And the attachment to the cover body 15 of the bag main body 14 is carried out through the bolt 16 which penetrated the inclined surface part 15c formed in the corner part of the upper surface part 15a and the back surface part 15b of the cover body 15. For example, the bolt head does not protrude rearward as in the case where the bolt is penetrated from the back surface portion 15b, and the bolt head is connected to the upper surface portion 15a and the back surface portion 15b in the inclined surface portion 15c. It can be assembled in a state where all or part of it can be accommodated, and compactness can be achieved.
[0013]
Further, since the housing 13 is for attaching the cover body upper surface portion 15a to the handrails 9 and 10, the attachment of the housing 13 to the handrails 9 and 10 is in a state straddling the front and rear of the handrail or the left and right, In other words, it can be attached to the handrails 9 and 10 so as to project both front and rear or left and right, thereby reducing the amount of projection from the handrails 9 and 10 and interfering with the operator operating in the driver's seat 6. It can be avoided that the amount of outward protrusion becomes large and hits an external obstacle. In addition, the mounting of the housing 13 to the handrail 9 or 10 is performed by tightening both the leg portions of the mounting bracket 17 having a substantially inverted U shape, so that the mounting of the housing 13 at an arbitrary position is simple. It will be a firm one.
[0014]
In addition, the housing 13 can adjust the left and right irradiation angle by loosely penetrating the legs 15 of the mounting bracket 17 into a long hole 15d formed in the upper surface portion 15a of the cover body. The vertical illumination angle can be adjusted by turning the shaft 10 as a support shaft. By fixing the nut with the vertical and horizontal illumination angles adjusted, mounting at an arbitrary position can be performed simultaneously with the setting of the illumination angle. It is convenient to be able to do it. Incidentally, it goes without saying that for adjusting the left and right irradiation angle, the long hole 17d can be formed into an arc instead of being linearly fitted and loosely fitted.
[0015]
Further, in this case, when the housing 13 is attached to, for example, the intermediate frame 12f of the front handrail 9, as shown in FIGS. 4 and 5, it is attached to the right side of the portion bent obliquely rearward on the left end side. In this case, the attached housing 13 is effectively protected on the left side by the intermediate frame 12f, the frame portion bent obliquely rearward of the lower frame 12a, and the left frame 12d. good.
[0016]
As for the mounting posture of the housing of the present invention, it can be attached not only to the housing facing in the left-right direction, but also to the housing facing in the vertical direction and the front-rear direction. Of course, it goes without saying that the vertical and horizontal directions and the front and rear directions of the housing vary depending on the mounting position and posture.
[0017]
Furthermore, the present invention can also be implemented in an ultra-small swivel excavator 20 as in the second embodiment shown in FIG. The hydraulic excavator 20 includes various member devices such as the lower traveling body 21, the upper swing body 22, the driver's seat 23, the dozer 24, the bucket 25, and the half canopy 26 as usual. Front and side handrails 27 and 28 are provided on the left side. The front handrail 27 is formed of a substantially rectangular frame and is attached by fixing the lower frame 27a and the right frame 27b to the base of the revolving structure frame 22a and the half canopy 26 with bolts. The upper side frame 27c of the front handrail 27 is bent at the left side diagonally left rearward, and the left side part of the lower side frame 27a is bent diagonally left rearward upward, and the leading ends thereof are left side frame 27d. It is connected by.
On the other hand, the side handrail 28 is attached by fixing both ends of the side handrail 28 to the side and the rear of the driver's seat 23, although the side handrail 28 is bent in a substantially L shape in plan view.
[0018]
Since the casing 13 has the same configuration as that of the first embodiment, its details are omitted, but in the drawing, the casing 13 is attached to the upper frame 27c of the front handrail 27. Needless to say, it can be attached to any position of the handrails 27 and 28. And by doing in this way, like the micro excavator 20 of the ultra-small turning type, in the case where there is no room for securing the mounting space of the housing 13 on the revolving body frame 22a, the housing 13 can be optionally attached. it can.
