The rotating mechanism 8 includes a pedestal 20 provided on the rear side of the vehicle body 3, a rotating shaft 21 provided at the upper end of the pedestal 20, and a lower end (for example, the lowest vertex) attached to the rotating shaft 21. , a link mechanism 22 that connects the storage container 7 and the pedestal 20 or the vehicle body 3, and a hydraulic cylinder 23 for a rotating mechanism connected to the link mechanism 22. ing.
ところで、前記リンク機構２２は、例えば台座２０や車体３に下方基端部が接続する第１リンク２２ａと、この第１リンクの位置変位する自由端部に接続すると共に、上方基端部が収納容器７の最下部の頂点部分よりも離れた部位に接続する連接棒２２ｂを有する「二つ手リンク」が採用されている。そして、圧力媒体で作動する回動機構用油圧シリンダー２３の作動杆２３ａの先端部は、第１リンク２２ａと連接棒２２ｂの位置変位可能な連結部位Ｐに接続されている。
By the way, the link mechanism 22 includes, for example, a first link 22a whose lower base end is connected to the pedestal 20 or the vehicle body 3, and a free end portion of the first link that is displaced. A "two-handed link" is employed that has a connecting rod 22b that connects to a portion of the container 7 that is more remote than the lowermost apex. The distal end of the operating rod 23a of the hydraulic cylinder 23 for the rotating mechanism, which is operated by pressure medium, is connected to a positionally displaceable connecting portion P between the first link 22a and the connecting rod 22b.
したがって、実施形態では、前述した回転軸２１が支点、該作動杆２３ａの突出先端部（第１リンク２２ａと連接棒２２ｂの連結部位）が力点、そして、リンク機構２２の連接棒の収納容器７の前方側底面部の適宜箇所に接続する基端部が重点ということになる。
Therefore, in the embodiment, the rotating shaft 21 described above is the fulcrum, the projecting tip of the operating rod 23a (the connecting portion of the first link 22a and the connecting rod 22b) is the power point, and the connecting rod storage container 7 of the link mechanism 22 The base end portion connected to an appropriate location on the bottom surface portion on the front side of is the main point.
しかして、運搬車１が水平面を走行する時には、回動機構用油圧シリンダー２３の作動杆２３ａを原点位置に位置させることにより、収納容器７の上端部を略水平とし、法面２上においては、作動杆２３ａを縮めることにより回動軸２１を支点に収納容器７を前方に回動させることで上端部を略水平に維持する。この回動機構用油圧シリンダー２３の作動杆２３ａは前述の前方側の緩い傾斜面に接続されている。
Thus, when the cart 1 travels on a horizontal surface, the operating rod 23a of the hydraulic cylinder 23 for the rotation mechanism is positioned at the original position so that the upper end of the storage container 7 is substantially horizontal. By retracting the operating rod 23a, the storage container 7 is rotated forward about the rotating shaft 21, thereby maintaining the upper end substantially horizontally. The actuating rod 23a of the hydraulic cylinder 23 for the rotating mechanism is connected to the gently inclined surface on the front side described above.
また、被運搬物１９を排出する際には、作動杆２３ａを伸長すると、前述した回転軸２１が支点となると共に、該作動杆２３ａの突出先端部が力点、連接棒の収納容器７の底面部に接続する基端部が重点となることから、収納容器７を後方側へ９０度を超えて回動させることができる。したがって、収納容器７の内部の被運搬物１９を確実にすべて排出することができる。
Further, when the object 19 to be conveyed is discharged, when the operating rod 23a is extended, the rotating shaft 21 described above becomes a fulcrum, and the projecting tip of the operating rod 23a serves as a power point, thereby Since the base end portion connected to the portion is the main point, the storage container 7 can be rotated rearward by more than 90 degrees. Therefore, all the objects 19 to be transported inside the storage container 7 can be reliably discharged.
ところで、後方側へ９０度を超えて回動させるとは、図３に示すように、略水平面上に車体が位置する場合において、収納容器７が９０度よりも下方側まで回動する状態をいう。このような状態まで収納容器７が後方側へ回動できることにより、収納容器７の内部の被運搬物１９を確実に排出することができる。
By the way, the term "rotate rearward by more than 90 degrees" refers to a state in which the storage container 7 is rotated downward by more than 90 degrees when the vehicle body is positioned substantially on a horizontal plane as shown in FIG. say. Since the storage container 7 can be rotated rearward to such a state, the transported object 19 inside the storage container 7 can be reliably discharged.
なお、本実施形態においては、後方側へ９０度を超えて回動可能となるように、台座２０を介して回動軸２１を設けているが、車体３の後端部側を切り欠く等により収納容器７の回動スペースを確保することができる場合には、回動軸２１を車体３に直接設けてもよい。
In this embodiment, the pivot shaft 21 is provided through the pedestal 20 so that it can be rotated rearward by more than 90 degrees. If a space for rotating the storage container 7 can be secured by using the above-mentioned structure, the rotating shaft 21 may be provided directly on the vehicle body 3 .
法面２で作業を行なう場合、図４に示すように平面視において略逆ハの字状になるように運搬車１のウインチ６のワイヤー５を法面２上のアンカー２４にそれぞれ接続し、作業位置まで運搬車１を移動させる。
When working on the slope 2, as shown in FIG. 4, the wires 5 of the winch 6 of the truck 1 are connected to the anchors 24 on the slope 2 so as to form a substantially inverted V shape in plan view, The truck 1 is moved to the working position.
このとき、図５に示すように作業機械９の操縦席１０や収納容器７の上端部が略水平状態になるように角度調節手段１１や回動機構８を調節する。
At this time, the angle adjustment means 11 and the rotation mechanism 8 are adjusted so that the operator's seat 10 of the work machine 9 and the upper end of the storage container 7 are in a substantially horizontal state as shown in FIG.
作業位置に到達したら油圧ショベル９によって削孔、掘削等の作業を行い、これらの作業により発生した土砂等の被運搬物１９を図６に示すように、油圧ショベル９のバケット１８によって収納容器７へ収納する。
After reaching the working position, the hydraulic excavator 9 performs drilling, excavation, and other work, and as shown in FIG. to store.
収納容器７に被運搬物１９を収納した後、運搬車１を被運搬物１９の排出場所まで移動させた後、図７に示すように回動機構８によって収納容器７を後方側へ回動させ、被運搬物１９を排出する。
After the object 19 to be transported is stored in the storage container 7, the transport vehicle 1 is moved to the discharge place of the object 19 to be transported. and the object 19 to be transported is discharged.
なお、本発明の実施形態においては、作業機械を有する運搬車について説明したが、作業機械を有さない運搬車としてもよい。また、作業機械は油圧ショベルだけでなく、削孔機やその他、法面で作業を行うことができる既存の作業機械を搭載することができる。
In addition, in the embodiment of the present invention, a transport vehicle having a working machine has been described, but a transport vehicle without a working machine may be used. In addition, the working machine can be not only a hydraulic excavator but also a drilling machine and other existing working machines that can work on slopes.
