Description

  The present invention relates to a work machine, and more particularly to a work machine in which an arrangement such as a hydraulic hose is arranged in a narrow space.

  Conventionally, a technique for fixing hydraulic piping of a work machine has been proposed. For example, in Patent Document 1, a plate (3) with a screw hole is fixed to a machine body or a work attachment, and a hydraulic pipe (8, 9, 10, 11) is provided with a screw hole by using an additional pipe clamp (30). A pipe clamp device for fastening and fixing to a plate (3) with fastening bolts (6, 7) is shown (see FIG. 1).

Japanese Utility Model Publication No. 2-18986

  However, in Patent Document 1, when there is some structure in the vicinity of the surface on the side where the fastening bolt (7) is inserted in the clamp fitting (30) for additional piping, the fastening bolt (7) cannot be inserted. There is sex. In other words, in Patent Document 1, when two structures are close to each other, it is difficult to reliably hold a routing object such as a hydraulic pipe routed in the space between the two structures.

  Then, an object of this invention is to provide the working machine which can hold | maintain the routing thing routed in the space of two structures adjacent to each other reliably.

In order to achieve the above object, the present invention is a work machine having a configuration in which a routing object is routed in a space sandwiched between a first structure and a second structure, wherein the first structure An attachment surface extending from the first to the second structure, and attached to the attachment member provided on the first structure so as to face the first structure with a gap therebetween. A plate-like member having a shape elongated in a direction substantially orthogonal to the arrangement direction of the arrangement object, and a holding member that holds the arrangement object, and an extended end of the plate-like member At least one of the plate-shaped members is an extending portion that bends substantially at right angles to the facing surface facing the first structure and extends toward the first structure, and is attached to the mounting surface. An elongated portion, and the holding member is provided on the facing surface; Wherein is disposed at a position overlapping the extending portion, wherein the gap is formed between the holding member between said opposing surfaces, providing a working machine said cabling comprises said gap, characterized in Rukoto is routed in doing.

  Further, the extending portion is configured as a bolt mounting surface in which a bolt hole for inserting a bolt for fixing the plate-shaped member to the mounting surface is formed, and the insertion direction of the bolt hole is determined by the insertion direction of the plate-shaped member. It is preferable that the holding member is disposed on an axial extension line of the bolt when the bolt is inserted through the bolt hole.

  According to the present invention, even if both the first structure and the second structure are close to each other, it is possible to reliably hold the routing object that is routed in the space between the two. .
