【考案の詳細な説明】
本考案はダンプトラックのリヤゲート装置に関するもの
である。[Detailed Description of the Invention] The present invention relates to a rear gate device for a dump truck.
従来大形ダンプトラックのほとんどはリヤゲートが装着
されていなかったため、不整地、積上りの現場等におい
ては、積載走行時、荷物がベッセル後端よりこぼれ落ち
るという不具合があった。Conventionally, most large dump trucks were not equipped with a rear gate, which caused problems such as cargo spilling out of the rear end of the vessel when driving on rough terrain or at loading sites.
また、リヤゲートが装着されている車両についても、ダ
ンプ時にはゲートを上方に持上げるか、ベッセル後端に
設けられたヒンジを中心に、旋回させるタイプのもので
あったために、大きな岩石の排出時にはゲートに当って
しまう不具合があった。Additionally, for vehicles equipped with rear gates, when dumping, the gate was either lifted upwards or rotated around a hinge provided at the rear end of the vessel, so when dumping large rocks, the gate There was a problem where it hit.
本考案は上記の事情に鑑みなされたものであって、その
目的とするところはダンプ時にはリヤゲートをベッセル
の下側へ引込むようにして大きな岩石の排出もスムーズ
に行なうことができるようにすることにある。The present invention was developed in view of the above-mentioned circumstances, and its purpose is to make it possible to smoothly discharge large rocks by retracting the rear gate to the lower side of the vessel during dumping.
以下、本考案を図面を参照して説明する。Hereinafter, the present invention will be explained with reference to the drawings.
図面中１はベッセルであり、２はリヤゲートである。In the drawings, 1 is a vessel, and 2 is a rear gate.
リヤゲート２の両端部の支持アーム８はベッセル１の両
端部のトラニオン４に回転可能に取付けである。Support arms 8 at both ends of the rear gate 2 are rotatably attached to trunnions 4 at both ends of the vessel 1.
車体フレーム９の後端にはブラケット５が固着しである
。A bracket 5 is fixed to the rear end of the vehicle body frame 9.
前記支持アーム８の先端部には球面ブツシュ６とピン１
０とによりロッド３の上端部が連結してあり、ロッド３
の下端部はブラケット５に植設したピン１１に球面ブツ
シュ１２を介して取付けである。A spherical bush 6 and a pin 1 are provided at the tip of the support arm 8.
The upper end of the rod 3 is connected to the rod 3 by
The lower end of the bracket 5 is attached to a pin 11 installed in the bracket 5 via a spherical bushing 12.
しかして、ベッセル１の上昇に連動してリヤゲート２は
ロッド３にその一端を押上げられトラニオン４を中心に
旋回し、第１図に示すようにベッセル１の下側へ引込ま
れるようになる。As the vessel 1 rises, the rear gate 2 is pushed up at one end by the rod 3, rotates around the trunnion 4, and is pulled into the lower side of the vessel 1 as shown in FIG. .
本考案は以上のようになるから、積載走行時には、リヤ
ゲート２によりベッセル１後端からの荷こぼれを防止す
るとともに、ダンプ時にはリヤゲート２がベッセル１の
下側へ引込まれるため大きな岩石の排出時にもリヤゲー
ト２が邪魔になることなく、円滑なダンプ作業を行なう
ことができる。Since the present invention is as described above, when traveling with a load, the rear gate 2 prevents cargo from spilling from the rear end of the vessel 1, and when dumping, the rear gate 2 is retracted to the underside of the vessel 1, so when large rocks are discharged. Also, the dumping operation can be carried out smoothly without the rear gate 2 getting in the way.
