Description

[Detailed Description of the Invention] Industrial field of use [Technical Field] The present invention relates to a simple cab for a driver's cab, which is mainly installed in a construction machine, a work vehicle or the like.

PRIOR ART FIG. 6 is a perspective view of a small turning excavator equipped with a conventional canopy. In the figure, 1 is a lower traveling structure, 2 is an upper revolving structure, 3 is a driver's seat provided on the upper revolving structure 2, 4 is a canopy, 5 is a column of a canopy 4, 6 is a canopy, and 7 is an upper revolving structure 2. It is a work attachment attached to the front part. FIG. 7 is a perspective view showing the vicinity of the conventional canopy 4. In the figure, 8 is a side plate for guard.

Next, the configuration of the prior art canopy 4 will be described with reference to FIGS. 6 and 7. A pillar 5 is erected on the rear side of the driver's seat 3, a canopy 6 is attached to the upper end of the pillar 5 to cover the driver's seat 3, and a side plate 8 for a guard is provided on one of the left and right side surfaces of the driver's seat 3. The front part, the rear part and the other side part are formed in an open state. The side plate 8 for the guard is provided on the side facing the work attachment 7 when the driver sits in the driver's seat 3 to drive, based on safety considerations. Further, since the upper-part turning body 2 of the small turning excavator is set so as to turn within the range of the trailing end turning radius, one end corner portion of the canopy 6 (the portion marked with a in FIG. 7) is slanted. It has a shaved shape.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In a small swing excavator, the outer periphery of the upper swing body in plan view is minimally configured so as to substantially coincide with the circumference of the rear end turning radius. For this reason, the front part, the rear part, and one side part of the canopy are formed in an open state for reasons of equipment layout and manufacturing costs. Therefore, even if the driver desires to attach the front panel having the windshield in response to the work situation, the weather situation, etc., the installation cannot be done.

It is an object of the present invention to solve the above problems and provide a simple cab in which a front panel can be attached and detached as required.

Means for Solving the Problems The means of this invention taken to solve the above problems are: A stay member is detachably provided on the front side of the side surface portion of the canopy which is formed in an open state. Also, attach the plate with tightening holes to the front of the side plate for the guard, and c. For the plate with tightening hole and the stay member,
It is configured to attach and detach the front panel.

Action a. When, for example, a grapple saw or the like is attached to the work attachment to perform cutting work on wood, cutting waste of wood may be scattered during the work and the driver may be full of cutting waste. In such cases, it is necessary to attach the front panel. At that time, first, a stay member is attached to the front side of the canopy formed in the open state, and a plate with a fastening hole is attached to the front portion of the guard side plate. Then, the front panel is attached to the plate with the fastening hole and the stay member.

B. The front panel can be removed from the simplified cab if it is not needed.

Embodiment Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing the vicinity of a simple cab 9 of the present invention equipped with a front panel. In the figure, 2 '
Is the upper revolving structure, 3'is the driver's seat, 10 is the front panel, 1
Reference numerals 1 and 12 are windshields of the front panel 10. It should be noted that the upper revolving structure 2'and the canopy 6'are respectively cut at one end corners (described in the section of the prior art), so that the front panel 10 is seen in plan view from the front panel 10.
It is shaped like a box. FIG. 2 is A- of FIG.
It is the sectional view seen from A. In the figure, 8'is a side plate for guard, 13 is a plate with fastening holes attached to the side plate for guard 8 ', 14 is a frame of the front panel 10, 11 and 12 are windshields, and 15 and 16 are weather strips, respectively. , 1
7 is a mounting plate fixed to the frame 14, 18 is the frame 1
4 is a bolt member fixed to 4, a nut member, 20 is a stay member, 21 is a plate with a tightening hole fixedly provided to the stay member 20, and 22 is a tightening bolt nut. Figure 3 shows
FIG. 7 is a perspective view of the vicinity of the simple cab 9 when only the plate 13 with a fastening hole and the stay member 20 are attached. In the figure, 23 is a plurality of tightening holes drilled in the tightening hole plate 13, 21 is a tightening hole plate fixed to the stay member 20, and 24 is a tightening hole plate 21. A plurality of tightening holes provided, 31, 32 are mounting flange portions provided at the upper and lower ends of the stay member 20, respectively, and 33 is a bolt member. The plates 13 and 21 with tightening holes may be formed of a plurality of small plate members, and the respective plate members may be provided with tightening holes. FIG. 4 is a cross-sectional view of the front part of the side plate 8'for a guard as seen from BB in FIG. In the figure,
Reference numeral 25 is a vertical girder portion at the front end of the guard side plate 8 ', 26 is a side glass, 27 is a weather strip, 28 is a sealing member, and 29 is a tightening bolt and nut for tightening the tightening plate 13. FIG. 5 shows the stay member 20 as seen from CC in FIG.
FIG. In the figure, 30 is a seal member, and 21 is a plate with a fastening hole which is integrally fixed to the stay member 20.

Next, the structure of the simple cab 9 according to the present invention is shown in FIG.
Referring to FIG. A stay member 20 is detachably provided on the front side of the side surface portion formed in the open state of the canopy,
When mounting the stay member 20, the mounting flange portion 31 at the upper end portion thereof is on the lower surface of the canopy 6 ', the mounting flange portion 32 at the lower end portion thereof is on the floor plate 34 of the upper swing body 2', and the bolt member 33.
The side plate 8'for the guard, and the plate 25 with the tightening hole to the vertical girder 25 on the front side of the guard side plate 8 '.
The plate with fastening holes and the plate 21 with fastening holes of the stay member 20 to the front panel.
It is configured so that 10 can be attached and detached.

Next, the function and function of the simple cab 9 according to the present invention will be described. When the driver mounts the front panel 10 in response to work conditions, weather conditions, etc., first, the stay member 20 is fastened to the front side of the open canopy and the front side of the guard side plate 8 '. Install plate 13 with holes. Then, the plate 13 with the tightening hole and the stay member 20.
For, attach the front panel 10. Next, when the front panel 10 is not needed, the front panel 10 can be removed from the simple cab.

Effect of the Invention In the simple cab according to the present invention, a stay member is detachably provided on the front side of the side surface of the canopy that is formed in an open state, and a plate with a tightening hole is attached to the front of the side plate for guard. I chose Therefore, when the driver wants to attach the front panel in response to work conditions, weather conditions, etc., the front panel can be easily attached. When the front panel is not needed, the front panel can be removed from the simple cab. The cost of this front panel is low, and the driver can easily cover the front side of the driver's seat with this front panel.

Therefore, in the construction machine and work vehicle equipped with the simple cab according to the present invention, the driving comfort of the driver is improved.
