Description

The present invention relates to a garbage truck whose inside can be seen and a method for manufacturing the same, which is used in on-site lessons for learning.

Conventionally, a so-called skeleton garbage truck has been known in which the inside can be seen so that the contents of the garbage truck can be known and the garbage problem can be considered as a familiar thing. In this skeleton garbage truck, a transparent acrylic plate or the like is provided on the side wall of the garbage storage box so that the garbage can be observed to be pushed inside.

By the way, as in Patent Document 1, there is a garbage truck having a double cross section of a garbage truck. Since this garbage truck is relatively large, it has a closed cross section to increase the rigidity of the side wall of the garbage truck.

On the other hand, the dust storage box of a garbage truck smaller than Patent Document 1 has a single and curved side wall in order to increase the internal volume and improve the appearance (see, for example, Patent Document 2). ).

A flat plate-shaped transparent plate 11 inside the input box is attached to the window portion 6d inside the input box.

A side window portion 4b is also provided on the side wall 4a of the dust storage box 4, and a large side transparent plate 12 is attached to the side window portion 4b. This detailed structure will be described later.

As shown in FIG. 3, a front window portion 4d is also provided on the left side of the front wall portion 4c of the dust storage box 4. A plate-shaped front transparent plate 13 is also attached to the front window portion 4d. It is desirable that these transparent plates 10 to 13 are made of, for example, a flat polycarbonate resin plate having a thickness of 3 mm to 5 mm and a clear color, hard-coated, and the back side of the peripheral edge is printed in black. Not limited to that. In the present embodiment, the front right side of the dust storage box 4 is closed by the opaque plate member 14, but conversely, the front side transparent plate 13 may be provided on this side, and both are provided. It may have been.

Next, the configuration of the side window portion 4b will be described in detail. As shown in FIGS. 2 and 4, the side wall 4a of the dust storage box 4 includes an outer panel 20 having a side opening 20a corresponding to the side window portion 4b. The outer panel 20 is made of, for example, a plate-shaped steel plate, and for example, bulging portions 20b and 20c are formed above and below the trapezoidal side opening 20a. The corners of the bulging portions 20b and 20c are curved to match the curved shape of the dust input box 6. The upper and lower bulging portions 20b and 20c are provided with horizontal flat surfaces 20d for frame mounting that are substantially parallel to each other and extend in the front-rear direction to form the side openings 20a. Before and after the side opening 20a, side inner side wall portions 20e bent so as to be curved are formed.

On the back side of the upper and lower bulging portions 20b and 20c of the outer panel 20, the inner panels 21 are attached by welding or the like at intervals on the left and right inside so as to be substantially flush with the side inner side wall portions 20e. .. As a result, the inner panel 21 and the outer panel 20 form a closed cross section at the upper and lower bulging portions 20b and 20c. The lower inner panel 21 may be connected to the guide frame 22 of the discharge plate 9 extending in the front-rear direction.

On the other hand, as shown in FIG. 4, the upper and lower centers of the lateral inner side wall portion 20e are curved. As shown in FIG. 5, a reinforcing member 23 extending in the vertical direction is welded so as to cover the surface side of the curved side inner side wall portion 20e. The reinforcing member 23 has a front reinforcing member 25 that covers the front side inner side wall portion 20e and a rear side reinforcing member 26 that covers the rear side side inner side wall portion 20e. The front reinforcing member 25 and the rear reinforcing member 26 are attached so that their main surfaces 25a and 26a are substantially flush with the upper and lower bulging portions 20b and 20c, respectively.

As shown in FIGS. 2, 5 and 6, the front reinforcing member 25 includes a frame mounting vertical flat surface 25b and a main surface 25a which are connected to the vertical edge of the main surface 25a on the side opening 20a side. It has a side opening 20a and an inclined surface 25c connected to the vertical edge on the opposite side. The front reinforcing member 25 is formed by a main surface 25a, a vertical flat surface 25b for mounting a frame, and an inclined surface 25c in a substantially U-shaped cross section, and is closed extending in the vertical direction between the side inner side wall portion 20e on the front side. It forms a cross section.

Further, the rear reinforcing member 26 is formed so as to extend obliquely in the vertical direction. The rear reinforcing member 26 has an inclined flat surface 26b for mounting a frame, which is connected to the vertical edge of the main surface 26a on the side opening 20a side. The rear reinforcing member 26 is formed by a main surface 26a and an inclined flat surface 26b for frame mounting in a substantially L-shaped cross section, and is vertically formed between the rear side inner side wall portion 20e and the opening frame portion 5a. It forms an extended closed cross section.

The front reinforcing member 25 and the rear reinforcing member 26 may be formed by bending, for example, one steel plate.

The frame member 24 is fitted into the frame-mounting horizontal flat surface 20d, the frame-mounting vertical flat surface 25b, and the frame-mounting inclined flat surface 26b on the peripheral edge of the lateral opening 20a thus formed. Specifically, the frame member 24 is, for example, a trapezoidal steel bar having a rectangular cross section welded along a side opening 20a, and is subjected to screw hole processing at predetermined intervals.

A flat plate-shaped side transparent plate 12 is attached to the frame member 24 from the back side by, for example, a bolt 24b.

The internal parts of the dust storage box 4 and the dust input box 6 may be colored differently in order to make the movement easier to see. Further, the signboard 25 may be provided on the bulging portion 20b above the side window portion 4b.

Next, a method of manufacturing the garbage truck 1 according to the present embodiment will be described.

First, for example, a side opening 20a corresponding to a window portion is opened in one steel plate, and bulging portions 20b and 20c are bent above and below the side opening 20a to form an outer panel 20. For example, a steel plate having a thickness of about 3 mm is bent by a press machine and a portion of the side opening 20a is cut out.

Next, the inner panel 21 is attached so as to be continuous from the back side of the bulging portions 20b and 20c to the lateral inner side wall portions 20e on the front and rear peripheral edges of the lateral opening 20a. The inner panel 21 may also be formed by bending a bent steel plate having a thickness of about 3 mm in advance so as to be continuous with the side inner side wall portion 20e, and welding the inner panel 21 to the outer panel 20 by welding or the like.

Next, as shown in FIGS. 2 and 5, the reinforcing member 23 (front side reinforcing member 25, rear side reinforcing member 25) is continuous with the front and rear side inner side wall portions 20e and the bulging portions 20b and 20c of the side opening 20a. 26) is pasted from the front side. As for the reinforcing member 23, for example, a steel plate having a thickness of about 3 mm may be bent and formed in advance, and the reinforcing member 23 may be fitted and welded from the surface side of the side inner side wall portion 20e. At this time, it is preferable that the surfaces of the upper and lower bulging portions 20b and 20c and the surface of the reinforcing member 23 are flush with each other as much as possible.

Next, the frame mounting horizontal flat surface 20d formed on the peripheral edge of the side opening 20a by being surrounded by the upper and lower bulging portions 20b and 20c and the front and rear reinforcing members 23 (front side reinforcing member 25, rear side reinforcing member 26). , The frame member 24 is fitted into the vertical flat surface 25b for frame mounting and the inclined flat surface 26b for frame mounting. For the frame member 24, for example, four steel plates may be assembled by welding to provide screw holes 24a. The frame member 24 after fitting, the horizontal flat surface 20d for frame mounting, the vertical flat surface 25b for frame mounting, and the inclined flat surface 26b for frame mounting may be joined by welding. At this time, since these flat surfaces 20d, 25b, 26b are parallel to each other in the mounting direction of the frame member 24 (vehicle width direction) and have a width sufficiently larger in the mounting direction than the thickness of the frame member 24. It is easy to fit and position the frame member 24 while sliding it, and it is easy to weld.

Next, the flat plate-shaped side transparent plate 12 is attached to the frame member 24 from the back surface side. If the frame member 24 is provided with the screw holes 24a in advance as described above, the side transparent plate 12 can be securely fixed only by fastening the bolts 24b. Further, if the inner surface of the frame member 24 is flush with each other, it is easy to attach the flat side transparent plate 12.

As described above, in the present embodiment, the outer panel 20 is easily formed by press forming the bulging portion 20b or the like and cutting out the side opening 20a. Further, by attaching the inner panel 21 from the back surface side of the bulging portion 20b, a closed cross section that maintains the strength in the front-rear direction of the side window portion 4b is formed. Further, by providing the reinforcing members 23 before and after the side openings 20a, a surface continuous with the bulging portions 20b and 20c is formed, and thereby the upper and lower bulging portions 20b and 20c and the front and rear reinforcing members 23 are formed. The frame member 24 can be fitted into the window portion surrounded by (front side reinforcing member 25, rear side reinforcing member 26), and the flat plate-shaped side transparent plate 12 can be easily attached to the frame member 24. ..

In the present embodiment, since the outer panel 20 and the inner panel 21 form a closed cross section around the side window portion 4b, a decrease in strength due to the formation of the side window portion 4b is suppressed.

Further, by covering the unevenness of the inner surface due to the bulging portions 20b and 20c with the inner panel 21, dust is not caught and the loading of dust by the dust loading device is not hindered.

Further, by providing reinforcing members 23 in front of and behind the side opening 20a so as to be substantially flush with the bulging portions 20b and 20c, the appearance can be improved and a closed cross section can be formed in this portion as well. It is possible to suppress a decrease in strength due to the provision of 4b.

Further, since the flat plate-shaped side transparent plate 12 is attached to the frame member 24 having a flat back surface, it is easy to attach, and since the side transparent plate 12 is not curved, the inside does not look distorted. Absent.

Further, in the present embodiment, since the frame member 24 is welded to the horizontal flat surface 20d for frame mounting, the vertical flat surface 25b for frame mounting, and the inclined flat surface for frame mounting, the frame member 24 can be easily welded. A flat plate-shaped side transparent plate 12 can be attached to the frame member 24.

Further, since the dust input box 6 is also provided with the input box outer window portion 6c and the input box inner window portion 6d, the opening / closing cylinder 7, the sliding cylinder 8 and the like can be moved outside the left and right side walls 6a of the dust input box 6. Not only can it be seen, but it can also be seen that the dust is pushed into the dust storage box 4 through the rear opening 5.

Therefore, according to the garbage truck 1 according to the present embodiment, the large flat plate-shaped lateral transparent plate 12 can be easily provided while suppressing the decrease in strength as much as possible.
