Description
【発明の詳細な説明】
（産業上の利用分野）
本発明は、フォークリフト、ホイールローダ等車両の前
面で荷物の昇降及び運搬を行う重量物運搬車両に関する
。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a heavy goods transport vehicle, such as a forklift or a wheel loader, which lifts, lowers and transports goods at the front of the vehicle.
（従来の技術）
第３図、第４図に、コイルを荷役するラム付フォークリ
フト１を示す。ラム５および昇降台４は直立スるマスト
２，３をガイドとし上下する、マスト装置は車両の前方
に直立に支持されチルトシリンダ６により前後傾する。(Prior Art) FIGS. 3 and 4 show a forklift 1 with a ram for loading and unloading coils. The ram 5 and the lifting platform 4 move up and down using upright masts 2 and 3 as guides. The mast device is supported upright in front of the vehicle and is tilted back and forth by a tilt cylinder 6.
（発明が解決しようとする問題点） 前述のような従来装置には次のような問題点がある。(Problem to be solved by the invention) The conventional device as described above has the following problems.
■マスト装置を車両前方に有するため、マストにより運
転者の視界が阻害される（第４図において、Ｓ′域は視
界不良となる）。特にコイル荷役の様な車両中心線上の
荷役は操作に熟練を要する。- Since the mast device is located at the front of the vehicle, the driver's visibility is obstructed by the mast (in Fig. 4, visibility is poor in area S'). In particular, cargo handling on the vehicle center line, such as coil cargo handling, requires skill.
■昇降台がマスト内を上下する構造上、揚高りを得る為
にはマスト下降時の全高Ａおよび最大全高Ｂとして相当
の高さが必要である。■同様にマスト装置を車両前方に
置く為、前軸中心から昇降台４の前面までの距離Ｆが相
応に大きくなる。■Due to the structure in which the lifting platform moves up and down inside the mast, in order to obtain the lift height, a considerable amount of total height A and maximum total height B are required when the mast is lowered. ■Similarly, since the mast device is placed at the front of the vehicle, the distance F from the center of the front axle to the front of the lifting platform 4 becomes correspondingly large.
（問題点を解決するための手段）
従来のマスト装置の代りに平行リンクを車両とほぼ水平
となる様に置き、車両全高を極力低くすると共に１回転
支持点を車両最後方（はぼ後軸上）に設はリンク長を出
来る丈長くとシ、マストと同様の揚高を得られる様にす
る。更に、リンクを作動させる油圧シリンダの支持点を
フレーム側は車両前軸附近、リンク側はリンクのほぼ中
央附近に配列し、荷役装置として最大の効率効果を上げ
る構造とする。(Means for solving the problem) Instead of the conventional mast device, a parallel link is placed almost horizontally with the vehicle, the overall height of the vehicle is made as low as possible, and the one-turn support point is placed at the rearmost part of the vehicle (the rear axis of the vehicle). Above), make the link length as long as possible so that it can achieve the same lift height as the mast. Furthermore, the support points of the hydraulic cylinders that operate the links are arranged near the front axis of the vehicle on the frame side, and near the center of the link on the link side, creating a structure that maximizes efficiency as a cargo handling device.
（作用） 昇降台は平行リンクによシ支持されて昇降する。(effect) The lifting platform is supported by parallel links and moves up and down.
車両前面にマストがないので視界が良好であシ、運転者
は広い範囲で前方を見ながら運転並びに荷役操作を行う
。Since there is no mast at the front of the vehicle, visibility is good, and the driver can drive and handle cargo while looking ahead over a wide area.
（実施例） 第１図、第２図に本発明の実施例を示す。(Example) Embodiments of the present invention are shown in FIGS. 1 and 2.
シャシ−フレーム１１に接合した支持柱２１を車両後方
に設置し、リンク１２をシャフト乙により回転支持点１
６で支持柱２１に枢着する。A support column 21 connected to the chassis frame 11 is installed at the rear of the vehicle, and the link 12 is connected to the rotation support point 1 by the shaft B.
It is pivoted to the support column 21 at 6.
リンク１２のほぼ中央の回転支持点１５とシャシ−前軸
附近の回転支持点ｎとの間に油圧シリンダ１３を設ける
。コイル運搬用ラム５を具えた昇降台１７がリンク１２
の前端の回転支持点加に取付けられ、昇降台１７の上端
部の回転支持点１９と支持柱２１上端部の回転支持点１
８との間にアーム１４が取付けられる。A hydraulic cylinder 13 is provided between a rotational support point 15 at approximately the center of the link 12 and a rotational support point n near the chassis front shaft. A lifting platform 17 equipped with a coil transporting ram 5 is a link 12
The rotary support point 19 is attached to the front end of the lifting table 17 and the rotation support point 1 is attached to the upper end of the support column 21.
An arm 14 is attached between the arm 8 and the arm 8.
支持点１９〜２０問および１８〜１６間の距離は等しく
、油圧シリンダ１３の伸長によシリンジ１２が押し上げ
られても、これによりラム５の水平度はいささかも変化
することなく上昇、下降が可能である。The distances between support points 19-20 and 18-16 are equal, and even if the syringe 12 is pushed up by the extension of the hydraulic cylinder 13, the horizontality of the ram 5 can rise and fall without changing in the slightest. It is.
なお、第２図において、Ｅは運転者の目の位置、Ｓは視
界である。In addition, in FIG. 2, E is the position of the driver's eyes, and S is the field of view.
（発明の効果）
（１）マストを除去することにより、フォークリフトの
宿命的欠陥であるマストによる運転者の前方視界を飛躍
的に改善できる。(Effects of the Invention) (1) By removing the mast, the forward visibility of the driver due to the mast, which is a fatal flaw in forklifts, can be dramatically improved.
（２）リンクの回転支持点を車両の最後方に設けること
によシ、リンク前端の円弧軌道が大きくとれ直立するフ
ォークリフトのマスト（荷役装置）と同等の揚高が得ら
れる。(2) By providing the rotational support point of the link at the rearmost part of the vehicle, the arcuate trajectory of the front end of the link can be increased, and the lift height equivalent to that of an upright forklift mast (cargo handling device) can be obtained.
（３）マストの廃止により、昇降台下降時の全高を低く
できる。(3) By eliminating the mast, the overall height when lowering the platform can be lowered.
（４） ローラ、チェーン、転進部材等複雑なフォー
