（実公昭48−33123号公報参照）が、近年トレーラ
（コンテナ）の長尺化に伴ない、従来の傾倒装置
によつては積載物を排出するに足る十分な傾倒角
度が得られないという問題があつた。 Trailer tilting devices have been known for a long time (see Japanese Utility Model Publication No. 48-33123), but as trailers (containers) have become longer in recent years, conventional tilting devices have become difficult to eject loaded items. There was a problem that a sufficient tilt angle could not be obtained.
本発明は上記の点に鑑みてなされたもので、長
尺化されたトレーラであつても十分な傾倒角度が
得られるトレーラの傾倒装置を提供するものであ
る。 The present invention has been made in view of the above points, and it is an object of the present invention to provide a trailer tilting device that can obtain a sufficient tilting angle even for a long trailer.
以下、図面により本発明の実施例を説明する
と、Ａはトラクタで、その車体枠１には支柱２が
立設されており、この支柱２の外側でかつ先端に
は左右一対のリフト腕３，３の基端が枢支連結４
され、また、このリフト腕３，３の他端には筒部
材５，５が固着されている。 Hereinafter, an embodiment of the present invention will be described with reference to the drawings. A is a tractor, and a support column 2 is erected on the body frame 1 of the tractor. A pair of left and right lift arms 3, The base end of 3 is a pivot connection 4
Further, cylindrical members 5, 5 are fixed to the other ends of the lift arms 3, 3.
ところで、前記リフト腕３と支柱２間には扛上
装置、すなわち、油圧シリンダ６が配設されてお
り、この油圧シリンダ６の伸縮作動により前記リ
フト腕３を枢支連結４部の回りに起伏させること
ができる。 By the way, a lifting device, that is, a hydraulic cylinder 6 is disposed between the lift arm 3 and the support column 2, and the expansion and contraction of the hydraulic cylinder 6 causes the lift arm 3 to rise and fall around the pivot connection 4. can be done.
一方、前記筒部材５，５には摺動杆７，７が嵌
挿され、この摺動杆７，７の先端には連動部材８
が固着されて摺動部材９が形成されている。 On the other hand, sliding rods 7, 7 are fitted into the cylindrical members 5, 5, and an interlocking member 8 is attached to the tips of the sliding rods 7, 7.
are fixed to form the sliding member 9.
そして、前記連結部材８とリフト腕３，３に架
設した桁材１６間には伸縮装置、すなわち、油圧
シリンダ１０が配設されており、この油圧シリン
ダ１０の伸縮作動により摺動部材９をリフト腕３
に対し伸縮させることができる。 A telescoping device, that is, a hydraulic cylinder 10 is disposed between the connecting member 8 and the beam member 16 installed on the lift arms 3, 3, and the sliding member 9 is lifted by the telescoping operation of the hydraulic cylinder 10. arm 3
It can be expanded and contracted.
さらに、前記連結部材８にはアーム１１，１１
を介してセミトレーラ１２に対する連結器１３が
枢支１４されている。 Further, the connecting member 8 includes arms 11, 11.
A coupler 13 to the semi-trailer 12 is pivotally supported 14 via the semi-trailer 12 .
なお、図中１５はセミトレーラ１２の後輪乗上
台であり、セミトレーラ１２を傾倒した際、セミ
トレーラ１２の後端が地面に接触することを防止
するものである。 In addition, 15 in the figure is a rear wheel platform of the semi-trailer 12, which prevents the rear end of the semi-trailer 12 from contacting the ground when the semi-trailer 12 is tilted.
次に本発明実施例の作動について説明すると、
まず、後輪乗上台１５上にセミトレーラ１２の後
輪を後退により乗せた後、ブレーキ装置を緩めて
扛上装置である油圧シリンダ６を伸長させると、
トラクタＡの後退と相俟つてトレーラ１２は傾動
を開始する。 Next, the operation of the embodiment of the present invention will be explained.
First, after backing up the rear wheels of the semi-trailer 12 on the rear wheel platform 15, the brake device is loosened and the hydraulic cylinder 6, which is a hoisting device, is extended.
As the tractor A moves backward, the trailer 12 starts tilting.
油圧シリンダ６の伸長が完了すれば、次いで伸
縮装置である油圧シリンダ１０を伸長させるとト
レーラ１２はさらに傾動し、第１図鎖線で示す傾
動角度を得ることができ、トレーラ１２の積載物
を地下サイロ等へ排出することができる。 When the extension of the hydraulic cylinder 6 is completed, the trailer 12 is further tilted by extending the hydraulic cylinder 10, which is a telescoping device, to obtain the tilting angle shown by the chain line in FIG. It can be discharged to a silo, etc.
積載物の排出が終了すれば順次油圧シリンダ
６，１０を縮小させることにより、トレーラ１２
を走行状態に復帰させることができる。 When the discharge of the loaded material is completed, the trailer 12 is moved by sequentially contracting the hydraulic cylinders 6 and 10.
can be returned to running condition.
なお、この場合、トレーラ１２は後輪乗上台１
５を用いて固定されたが、ピツトに排出する場合
には後輪を直接車止めを用いて固定した後、傾動
させればよい。 In this case, the trailer 12 has a rear wheel platform 1.
5, but when discharging into a pit, the rear wheel may be directly fixed using a wheel stopper and then tilted.
以上のように本発明によれば、リフト腕を起立

ことによつて長尺のトレーラに対しても充分な傾
倒角度を確保することができ、そのため長尺のト
レーラであつてもその内部に収容された積載物を
完全に排出することができるものである。 As described above, according to the present invention, by standing up the lift arm and then extending the sliding member from the lift arm, a sufficient tilting angle can be secured even for a long trailer. Even if the trailer is long, it is possible to completely discharge the cargo stored inside the trailer.
