本発明はダンプトラツクにおける天蓋開閉装置
に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a canopy opening/closing device for a dump truck.
一般にダンプトラツクの天蓋開閉装置にあつて
は法規上、側壁上方に長手方向に延びたシヤフト
を設けることが過積載につながることから禁じら

０１の外側に回転可能にシヤフト０２を設け、こ
のシヤフト０２にフレーム０３を取付け、前記シ
ヤフト０２とフレーム０３との間にキヤンバス０
４を張設した構造になつている。ところで、前記
構造のものを下方開放可能な側部煽戸の有する荷
箱に取付けた場合には、側部煽戸の回動中心は側
部煽戸上方内側であるが、天蓋開閉装置のシヤフ
ト０２は側部煽戸の外側にあるので、シヤフト０
２は側部煽戸の回動中心と同一線上には位置して
いない。 Generally speaking, in the case of a canopy opening/closing device for a dump truck, it is prohibited by law to provide a shaft extending in the longitudinal direction above the side wall, as this may lead to overloading. Therefore, in the past, a shaft 02 was rotatably provided on the outside of the side wall 01 of the cargo box as shown in FIG. 1, a frame 03 was attached to the shaft 02, and a canvas 0
It has a structure in which 4. By the way, when the structure described above is attached to a cargo box having a side door that can be opened downward, the center of rotation of the side door is on the upper inner side of the side door, but the shaft of the canopy opening/closing device 02 is on the outside of the side fan door, so shaft 0
2 is not located on the same line as the center of rotation of the side sliding door.
このため側部煽戸を下方開放した場合、シヤフ
ト０２も側部煽戸の回動中心を中心として回動す
ることになるので、シヤフト０２の前端に取付け
られた駆動装置の歯車もシヤフト０２とともに回
動することとなる。この歯車の回動により歯車と
駆動装置の電動モータとの距離は長くなるが、歯
車と電動モータとに掛け渡されたチエーンは長く
ならないので側部煽戸は回動できず、結局側部煽
戸が開けられないという問題があつた。 Therefore, when the side fan door is opened downward, the shaft 02 also rotates around the rotation center of the side fan door, so the gear of the drive device attached to the front end of the shaft 02 also rotates with the shaft 02. It will rotate. The rotation of this gear increases the distance between the gear and the electric motor of the drive device, but the chain that spans the gear and the electric motor does not become long, so the side fan door cannot rotate, and in the end, the side fan door cannot rotate. There was a problem that the door could not be opened.

状態で走行する。 The present invention has the above-mentioned configuration, and its operation will be explained next. When the present invention is running, the canopy bodies 16, 16 are rotated to the upper side of the cargo box 1 by the drive devices 22, 22 as shown by the solid line in FIG. 1. Cover the area above and drive in that state.

ものではない。 Next, when discharging from the side, the canopy body 16,
When the cargo box 1 is tilted to the side while keeping the solid line 16 in Fig. 5, the lashing devices 12, 12 come off and the side fan door 6 opens downward due to its own weight as shown in Fig. 6, and is discharged from the side. However, in that case, the short shafts 15, 15 should be placed on the same line as the rotation center X-X of the side sliding door 6.
Since the supporting members 14, 14 supporting the short shafts 15, 15 also rotate around the short shafts 15, 15 together with the side fan door 6, the canopy opening/closing device 13 It is designed so as not to impede the rotation of the side fan doors 6, 6. As described above, in the present invention, the short shaft, which is the rotation center of the canopy body, is provided on the line of the rotation center of the side fan door, so even when discharging from the side of the box, the rotation of the canopy body is Since the center itself does not move relative to the rotation center of the side fan door, the side fan door can be opened reliably without any interference from the canopy opening/closing device, and the side fan door Only short shafts are located higher up, so they cannot be subject to overloading and are not against the law.
