つぎに、前記コンテナCを積み降ろしするための荷役装置Loを備え、本発明にかかるセミトレーS上に、コンテナCを積載するためのコンテナ荷役車両Vについて、図9を参照して説明するに、このコンテナ荷役車両Vは、既に公知のものであるので、その構成を簡単に説明すると、このコンテナ荷役車両VのシヤシフレームFは、メインフレーム101上にサブフレーム102を一体に結合して構成され、シヤシフレーム101上には、該シヤシフレーム101と地上間でコンテナCの積み降ろしを行なうための荷役装置Loが設けられる。   Next, a container handling vehicle V for loading and unloading the container C and loading the container C on the semi-tray S according to the present invention will be described with reference to FIG. Since the container handling vehicle V is already known, its configuration will be briefly described. The palm frame F of the container handling vehicle V is configured by integrally connecting the subframe 102 on the main frame 101. On the palm frame 101, a cargo handling device Lo for loading and unloading the container C between the palm frame 101 and the ground is provided.

この荷役装置Loは、サブフレーム102に、基端が支軸104をもって回動自在に軸支され、その支軸104まわりに前後に起伏回動することができる荷役腕103を備えており、その荷役腕103は、基部腕103Aと、これに伸縮自在に嵌挿される先部腕103Bとより構成され、基部腕103Aと先部腕103B間には、伸縮シリンダ105が連結され、この伸縮シリンダ105の伸縮作動で、先部腕103Bは基部腕103Aに対して伸長したり、収縮したりすることができる。メインフレーム101と基部腕103A間には、リフトシリンダ106が連結され、このリフトシリンダ106の伸縮作動で荷役腕103を支軸104回りに前後に起伏回動させることができる。   This cargo handling device Lo is provided with a cargo handling arm 103 that is pivotally supported by a subframe 102 so that the base end thereof is freely rotatable about a support shaft 104 and can be swung up and down around the support shaft 104. The cargo handling arm 103 is composed of a base arm 103A and a tip arm 103B that is inserted into the base arm 103A in a telescopic manner. An extension cylinder 105 is connected between the base arm 103A and the tip arm 103B. With the telescopic operation, the front arm 103B can be extended or contracted with respect to the base arm 103A. A lift cylinder 106 is connected between the main frame 101 and the base arm 103 </ b> A, and the cargo handling arm 103 can be swung back and forth around the support shaft 104 by the expansion and contraction operation of the lift cylinder 106.

前記荷役腕103の先部腕103Bの先端には、フック107が設けられ、このフック107は、前記コンテナCの係止片50に係脱自在である。   A hook 107 is provided at the tip of the tip arm 103B of the cargo handling arm 103, and this hook 107 is detachable from the locking piece 50 of the container C.

コンテナ荷役車両Vのサブフレーム102の後端には、ローラ軸109が横架固定され、このローラ軸109の左右両端に、対をなす案内ローラ110,110が転動自在に軸支されている。メインフレーム101の後端左右には、一対のジャッキ111,111が設けられる。   A roller shaft 109 is horizontally fixed to the rear end of the subframe 102 of the container handling vehicle V, and a pair of guide rollers 110 and 110 are rotatably supported at both left and right ends of the roller shaft 109. . A pair of jacks 111 are provided on the left and right of the rear end of the main frame 101.

地上に載置されているコンテナCを荷役車両Vの車体フレームF上に積み込む場合には、リフトシリンダ106の伸長作動により荷役腕103を支軸104回りに後方に回動して荷役腕103先端のフック107を、コンテナCの係止片50に係合した後、リフトシリンダ106を収縮すれば、荷役腕103は前方に回動してコンテナCの前端が持ち上げられ、図9に鎖線で示すように、コンテナCの一対の主桁52,52は左右一対の案内ローラ110,10上に支持され、引き続く荷役腕103の前方への回動により主桁52,52は案内ローラ110,110に案内されつつコンテナCは車体フレームF上に積載される。   When the container C placed on the ground is loaded on the vehicle body frame F of the cargo handling vehicle V, the lifting arm 106 is extended to rotate the cargo handling arm 103 rearward around the support shaft 104 so that the tip of the cargo handling arm 103 is reached. When the lift cylinder 106 is contracted after the hook 107 of the container C is engaged with the locking piece 50 of the container C, the cargo handling arm 103 is rotated forward and the front end of the container C is lifted. As described above, the pair of main girders 52 and 52 of the container C are supported on the pair of left and right guide rollers 110 and 10, and the main girders 52 and 52 are moved to the guide rollers 110 and 110 by the forward rotation of the cargo handling arm 103. The container C is loaded on the vehicle body frame F while being guided.

本発明にかかるセミトレーラSにコンテナCを積載する場合に、コンテナCの主桁52,52を、その端部からセミトレーラSの後部荷台2F(あるいは前部荷台2R)の案内レール28,28上に載せ、スライドさせると共のその後部転動輪54,54および前部転動輪53,53を、補強部材31,31の案内プレート33,33上を転動させる。このとき、一対の案内片27,27(図8参照)に、コンテナCの主桁52,52が係合すると共に一対の案内レール28,28の傾斜案内面28a,28aに、後部転動輪54,54および前部転動輪53,53が係合して、コンテナCを正規の方向に誘導しつつ、後部および前部転動輪54,54;53,53を案内プレート33,33上に転動させ、これにより、コンテナCが、セミトレーラSに対して左右方向にずれている場合にも、コンテナCの縦中心軸線を、セミトレーラSの縦中心軸線と一致させて、図1に示すように、コンテナCをセミトレーラSの後部荷台2Rおよび前部荷台2F上の所定の位置に積載することができる。   When the container C is loaded on the semi-trailer S according to the present invention, the main girders 52 and 52 of the container C are placed on the guide rails 28 and 28 of the rear cargo bed 2F (or front cargo bed 2R) of the semi-trailer S from the end thereof. When mounted and slid, the rear rolling wheels 54 and 54 and the front rolling wheels 53 and 53 are rolled on the guide plates 33 and 33 of the reinforcing members 31 and 31. At this time, the main girders 52 and 52 of the container C are engaged with the pair of guide pieces 27 and 27 (see FIG. 8), and the rear rolling wheels 54 and the inclined guide surfaces 28a and 28a of the pair of guide rails 28 and 28 are engaged. , 54 and the front rolling wheels 53, 53 are engaged to guide the container C in the normal direction while rolling the rear and front rolling wheels 54, 54; 53, 53 onto the guide plates 33, 33. Thus, even when the container C is displaced in the left-right direction with respect to the semi-trailer S, the vertical center axis of the container C is made to coincide with the vertical center axis of the semi-trailer S, as shown in FIG. The container C can be loaded at predetermined positions on the rear cargo bed 2R and the front cargo bed 2F of the semi-trailer S.

本発明にかかるセミトレーラSを牽引移送するのに、トラクタT(図12参照)が用いられる。このトラクタTは従来公知のものであり、シヤシフレーム201に、連結器202が設けられ、この連結器202に、セミトレーラSの被連結部9が着脱自在に連結される。   A tractor T (see FIG. 12) is used to pull and transfer the semi-trailer S according to the present invention. The tractor T is a conventionally known tractor, and a connecting frame 202 is provided on the palm frame 201, and the connected portion 9 of the semi-trailer S is detachably connected to the connecting device 202.

つぎに、図10〜12を参照して、本発明のセミトレーラS上に、2台のコンテナCを積載する工程について説明する。   Next, with reference to FIGS. 10 to 12, a process of loading two containers C on the semi-trailer S of the present invention will be described.

〔セミトレーラSの後部荷台2R上に1台目のコンテナCを積載する工程(図10参照)〕
(1)セミトレーラSを適宜の作業場所に停車させ、その後部ジャッキJRを伸長させる。コンテナCを積載したコンテナ荷役車両Vを、セミトレーラSの後方に移動させ、該荷役車両Vの後端をセミトレーラSの後端に近接させる。その後にセミトレーラSの前部ジャッキJFを伸長させる。
[Process of loading the first container C on the rear loading platform 2R of the semi-trailer S (see FIG. 10)]
(1) The semi-trailer S is stopped at an appropriate work place, and the rear jack JR is extended. The container handling vehicle V loaded with the container C is moved rearward of the semi-trailer S, and the rear end of the handling vehicle V is brought close to the rear end of the semi-trailer S. Thereafter, the front jack JF of the semi-trailer S is extended.

(2)コンテナ荷役車両Vのジャッキ111を伸長させ、該荷役車両V上のコンテナCを、荷役装置Loを作動して該車両VからセミトレーラSの後部荷台2R上に移載する。後部荷台2R上に積載されたコンテナCは、前述のように、跳ね上がり防止手段a、他の跳ね上がり防止手段bおよび位置規制手段cの作動により所定位置に固縛される。   (2) The jack 111 of the container handling vehicle V is extended, and the container C on the cargo handling vehicle V is transferred from the vehicle V onto the rear loading platform 2R of the semi-trailer S by operating the cargo handling device Lo. As described above, the container C loaded on the rear cargo bed 2R is locked at a predetermined position by the operation of the splash prevention means a, the other splash prevention means b, and the position regulation means c.

なお、コンテナ荷役車両Vから後部荷台2RにコンテナCを移載する際に、後部荷台2Rは、前部荷台2Fよりも一段低くなっているので、コンテナCの移載作業がし易い。
〔セミトレーラSの前部荷台2F上に2台目のコンテナCを積載する工程(図11参照)〕
(3)つぎに、2台目のコンテナCを搭載した、コンテナ荷役車両VをセミトレーラSの前方に移動させ、該荷役車両Vの後端をセミトレーラSの前端に近接させる。このとき、セミトレーラSの前部ジャッキJFを所定量収縮して、セミトレーラSを前傾斜させる。
Note that when the container C is transferred from the container handling vehicle V to the rear loading platform 2R, the rear loading platform 2R is one step lower than the front loading platform 2F, so that the transfer operation of the container C is easy.
[Step of loading second container C on front loading platform 2F of semi-trailer S (see FIG. 11)]
(3) Next, the container handling vehicle V on which the second container C is mounted is moved in front of the semi-trailer S, and the rear end of the cargo handling vehicle V is brought close to the front end of the semi-trailer S. At this time, the front jack JF of the semi-trailer S is contracted by a predetermined amount, and the semi-trailer S is inclined forward.

(4)この状態のまま、前記(2)と同じく、コンテナ荷役車両V上のコンテナCを、荷役装置Loを作動して該車両VからセミトレーラSの前部荷台2F上に移載する。前部荷台2F上に積載されたコンテナCは、前述のように、跳ね上がり防止手段a、他の跳ね上がり防止手段bおよび位置規制手段cの作動により所定位置に固縛される。この場合、セミトレーラSは前傾姿勢をとることにより、コンテナCの積込作業が容易になる。   (4) In this state, the container C on the container handling vehicle V is transferred from the vehicle V onto the front loading platform 2F of the semi-trailer S by operating the handling device Lo as in the case (2). As described above, the container C loaded on the front loading platform 2F is locked at a predetermined position by the operation of the splash preventing means a, the other splash preventing means b, and the position restricting means c. In this case, the semi-trailer S takes a forward leaning posture so that the loading operation of the container C is facilitated.

〔2台のコンテナCの積載完了後、セミトレーラSをトラクタTで牽引する工程(図12参照)〕
(5)その後、コンテナ荷役車両Vは、セミトレーラSから離れ、該セミトレーラSの前端部の被連結部9に、トラクタTの連結器202を連結して、トラクタ・トレーラTTとし、前、後部ジャッキJF,JRを収縮して、トラクタTの走行駆動により、台車1にコンテナCを縦列積載したセミトレーラSを牽引走行して、それらのコンテナCを運搬する。
[Step of towing semi-trailer S with tractor T after loading of two containers C (see FIG. 12)]
(5) Thereafter, the container handling vehicle V is separated from the semi-trailer S, and the coupler 202 of the tractor T is coupled to the coupled portion 9 at the front end of the semi-trailer S to form a tractor trailer TT. The JF and JR are contracted, and the tractor T is driven to drive the semi-trailer S in which the containers C are stacked in cascade on the cart 1 to carry the containers C.

なお、セミトレーラSへの2台のコンテナCの積み込み順序は、前述の場合と異なり、まず、前部荷台2F上に1台目のコンテナCを積載した後に、後部荷台2R上に2台目のコンテナCを積載するようにしてもよい。   The order of loading the two containers C onto the semi-trailer S is different from the above case. First, after loading the first container C on the front loading platform 2F, the second container C is loaded on the rear loading platform 2R. Container C may be loaded.

また、セミトレーラS上の2台のコンテナCを降ろす手順は、前記積み込みの手順と逆の操作を行なえばよい。   Further, the procedure for lowering the two containers C on the semi-trailer S may be performed in the reverse manner to the loading procedure.

つぎに、図13を参照して、本発明にかかるトレーラの使用例として、塵芥集積場の塵芥を、塵芥処理場に運搬する場合について説明する。

[2]港湾(A)において、コンテナ荷役車両V上のコンテナCを、セミトレーラSの後部荷台2Rおよび前部荷台2F上に縦列移載する。
[3]また、港湾(A)において、2台のコンテナCを縦列積載したセミトレーラSに、トラクタTを連結する。
[4]2台のコンテナCを積載した、トラクタ・トレーラTTは、そのまま運搬船STに搭載されて港湾(B)に運搬され、そこで港湾(B)に陸揚げされる。
[5]港湾(B)において、セミトレーラSからトラクタTが切り離される。
[6]さらに、港湾(B)において、セミトレーラSの2台のコンテナCは、コンテナ荷役車両Vに順に積み替えられて塵芥処理場へ搬送される。
[7]塵芥処理場にて塵芥を投棄して空となったコンテナCを積載したコンテナ荷役車両Vは、港湾(B)へと戻る。
[8]港湾(B)において、コンテナ荷役車両V上の空のコンテナCは、前記[1]の要領にてセミトレーラS上に縦列して搭載され、そのセミトレーラSにトラクタTが連結される。
[9]セミトレーラS上に2台の空のコンテナCを縦列搭載した、トラクタ・トレーラTTは、運搬船STに移載されて港湾(A)に陸揚げされる。
[10]港湾(A)において、セミトレーラS上の空のコンテナCは、コンテナ荷役車両Vに順に積み替えられて塵芥集積場へと搬送される。
Next, with reference to FIG. 13, as an example of use of the trailer according to the present invention, a case where the dust in the dust collection field is transported to the dust treatment site will be described.
[1] The container C containing the dust in the garbage dump is mounted on the container handling vehicle V and transported to the port (A).
[2] In the port (A), the containers C on the container handling vehicle V are transferred in tandem on the rear cargo bed 2R and the front cargo bed 2F of the semi-trailer S.
[3] In the port (A), the tractor T is connected to the semi-trailer S in which two containers C are stacked in series.
[4] The tractor trailer TT loaded with two containers C is mounted on the transport ship ST as it is and transported to the port (B), where it is landed at the port (B).
[5] The tractor T is separated from the semi-trailer S at the port (B).
[6] Further, in the port (B), the two containers C of the semi-trailer S are sequentially transferred to the container handling vehicle V and transported to the refuse disposal site.
[7] The container handling vehicle V loaded with the container C that has been emptied by dumping the dust at the refuse disposal site returns to the port (B).
[8] In the port (B), empty containers C on the container handling vehicle V are mounted in tandem on the semi-trailer S as described in [1], and the tractor T is connected to the semi-trailer S.
[9] The tractor trailer TT in which two empty containers C are vertically mounted on the semi-trailer S is transferred to the transport ship ST and landed at the port (A).
[10] In the harbor (A), the empty containers C on the semi-trailer S are sequentially loaded onto the container handling vehicle V and transported to the garbage dump.

以上のように、この使用例によれば、2台のコンテナCを積載可能の本発明にかかるセミトレーラSを利用して、複数のコンテナCを港湾(A)、(B)間で陸上および水上移送する場合に、高価なクレーンなどに荷役機械に依存することなく、比較的安価なトラクタTにより、複数のコンテナCを能率よく移送することができ、コンテナCの移送能率を高めると共に移送コストの大幅な低減を図ることができる。   As described above, according to this use example, a plurality of containers C can be placed between the ports (A) and (B) on land and on the water using the semi-trailer S according to the present invention that can load two containers C. When transporting, a plurality of containers C can be efficiently transported by a relatively inexpensive tractor T without relying on an expensive crane or the like for a cargo handling machine, increasing the transport efficiency of the containers C and reducing the transport cost. Significant reduction can be achieved.

以上、本発明の実施例について説明したが、本発明はその実施例に限定されることなく、本発明の範囲内で種々の実施例が可能である。   As mentioned above, although the Example of this invention was described, this invention is not limited to the Example, A various Example is possible within the scope of the present invention.

たとえば、前記実施例では、コンテナの積載順序は、セミトレーラの後部荷台上に1台目のコンテナを積載した後に、前部荷台上に2台目のコンテナを積載するようにしているが、セミトレーラの前部荷台上に1台目のコンテナを積載した後に、後部荷台上に2台目のコンテナを積載するようにしてもよい。また、前記実施例のコンテナ荷役車両に代えて他の公知の荷役手段を用いてもよい。   For example, in the above embodiment, the container loading order is such that after loading the first container on the rear loading platform of the semi-trailer, the second container is loaded on the front loading platform.
