Description

ミニショベルの横行構造に関するもので、ミニショベルのアタッチメントを取り付けるアーム及びブームを一体的支持した横行台車をショベルの旋回体の幅方向に横行させ、アーム先端に取り付けた作業機のアッタチメントを直線状に移動できるものに関する。 This is related to the traversing structure of a mini excavator, in which a traversing trolley that integrally supports the arm and boom to which the mini excavator attachment is attached is made to traverse in the width direction of the excavator revolving body, and the attachment of the work equipment attached to the tip of the arm is moved in a straight line. Concerning things that can be moved.

従来のミニショベルのアーム先端に作業機のアタッチメントをセットし、ブーム基部のスイングポストの揺動、及びブーム本体の平行屈折によりアタッチメントの移動を行っていたが、前記の揺動、屈折では旋回体からの半径が変化し、アタッチメントの横直線状作業が困難であった。 Conventionally, the attachment of the work equipment was set at the tip of the arm of a mini excavator, and the attachment was moved by swinging the swing post at the base of the boom and parallel bending of the boom body. The radius from the center changed, making it difficult to perform horizontal linear work with the attachment.

例えば、特開2000-309938の図5の平面図に示されるように、ブーム(7)が左右に揺動すると、バケット(12)が左右の位置では回転半径の変化分だけ(4)キャブ方向に移動しているのが分かる。本発明は、ショベルの先端に取り付ける作業機、例えばバケットの位置がショベルの旋回体の幅方向に直線状に移動するようにしようとするものである。即ち、作業機の作業範囲が長方形を描くようにするものである。 For example, as shown in the plan view of FIG. 5 of JP-A No. 2000-309938, when the boom (7) swings from side to side, the bucket (12) moves in the left and right positions by the amount of change in the rotation radius (4) toward the cab. I can see that it is moving to. The present invention is intended to allow the position of a working device, such as a bucket, attached to the tip of an excavator to move linearly in the width direction of the revolving body of the excavator. That is, the working range of the working machine is made to draw a rectangular shape.

図6は、巻掛け伝動式横行装置(8)を示し、シリンダー(81)とチェン(85)の絞りと繰り出しにより、横行台車(4)の台車固定部(89)をシリンダー(81)のストロークでチェン(85)の掛け数倍台車固定部(89)が移動する。図6ではチェン(85)が4本掛けのため横行台車(4)はシリンダー(81)のストロークの4倍移動できる。巻掛け伝動の掛け数は選択できる。 Figure 6 shows a winding transmission type traversing device (8), in which the carriage fixing part (89) of the traversing carriage (4) is moved by the stroke of the cylinder (81) by squeezing and feeding out the cylinder (81) and chain (85). The carriage fixing part (89) moves by the number of times the chain (85) is engaged. In FIG. 6, since there are four chains (85), the transverse carriage (4) can move four times the stroke of the cylinder (81). The number of winding transmissions can be selected.

図6に図示するように、ピストンロッド(82)は両ロッドで、図において(右側が絞られ、左側が繰り出し状態で、台車固定部(89)は右に横行移動したことになる。左側チェンは緩まないように常に緊張させ、横行台車(4)が遊ばないようにしている。(87)はチェン端部の固定端で、チェン(85)が緩まないように張力を発生させている。(83)移動フレーム、(84)は移動鎖車、(88)は固定フレームで横行フレーム(1)に固定されている As shown in FIG. 6, the piston rod (82) is a double rod, and in the figure (the right side is squeezed and the left side is extended, the trolley fixing part (89) has moved laterally to the right. (87) is a fixed end of the chain end, which generates tension to prevent the chain (85) from loosening. (83) is a moving frame, (84) is a moving chain wheel, and (88) is a fixed frame that is fixed to the transverse frame (1).

図7、図8,図9は横行台車の横行をネジ棒(801)の回転により、横行台車(4)のブラケット(803)(803’)間に遊嵌した不回転ナット(802)の組み合わせで横行台車(4)を横行させるものである。ネジ棒(801)は単数、複数を問わない。ネジ棒(801)はモーター(807)、チェン(806)、鎖車(805)により回転する。 Figures 7, 8, and 9 show a combination of a non-rotating nut (802) loosely fitted between brackets (803) (803') of a traversing truck (4) by rotating a threaded rod (801) to prevent the traversing truck from moving. The traversing cart (4) is made to traverse. The threaded rod (801) may be singular or plural. The threaded rod (801) is rotated by a motor (807), a chain (806), and a chain wheel (805).

図3の横行同調装置(11)は鎖車(111)とチェン(112)の代わりに歯車のラック、ピニオンでもよい。また、図6の横行装置は鎖車、チェンの代わりに滑車と鋼索でもよい。図6のチェンは(85)はローラーチェン、リンクチェンなどを問わない。 The traverse tuning device (11) in FIG. 3 may be a gear rack and pinion instead of the chain wheel (111) and chain (112). Further, the traversing device shown in FIG. 6 may be a pulley and a steel cable instead of a chain wheel or chain. The chain (85) in FIG. 6 may be a roller chain, a link chain, or the like.

ショベルを用いた作業機(アタッチメント)の作業範囲を前後左右の直線状の操作ができるので、長方形を描くような作業ができる。 The work area of the work equipment (attachment) using a shovel can be operated in a straight line, front, back, left, and right, so you can work in a rectangular manner.
