Description

In order to solve the above technical problems, one aspect of the present invention includes a lower traveling body, an upper revolving body pivotally mounted on the lower traveling body, a boom and an arm, and is installed on the upper revolving body Construction machine provided with the work machine being carried out and a plurality of pipelines provided to the work machine, wherein each of the plurality of pipelines is an error in the piping between which the mutually connectable joint is attached at the end A pipe connection structure having a connection preventing function is provided , and the pipe connection structure is a pair fixedly attached and fixed to a place separated from the joint of one pipe and a place separated from the joint of the other pipe. The clamp joint has a shape in which the opposing end faces are butt-to-fit and fitted, and a pair of identifications in which the vicinity of the separated end face opposite to the opposite end face is attached and fixed to predetermined positions of the pair of clamp joints. play When, with a shape that the engaging of the pair of identification plates, characterized in that it is different from the pattern in the conduit each.

Referring to FIG. 1, the dismantling machine 15 is an upper portion provided with a cab, a control device, a display device, a controller, an engine, various pipes (pipes) 14, a working machine 13 and the like in a crawler type lower traveling body 11. The rotating body 12 is rotatably mounted. The working machine 13 includes a boom, an arm, a fixed side bucket, a movable side bucket, a rotary base for rotatably supporting these buckets with respect to the arm, a bucket cylinder for driving the fixed side bucket, at least for watering Are provided including various pipes 14 and the like. Such a dismantling machine 15 is also called a swing type construction machine or a hydraulic shovel. In addition, since the structure itself of the disassembling machine 15 is well-known, description here is abbreviate | omitted.

Shapes fitted like the identification plate 4b for the identification plate 4a described above, the identification plate 4b 'for the identification plate 4a', and the identification plate 4b '' for the identification plate 4a '' are different patterns for each pipe connection type (pipeline) It is good if you attach it after doing. In such a case, since the connection can not be made if the mating partner is different, it is possible to prevent erroneous connection properly. Incidentally, the shape to be fitted is a shape other than the convex portions 6, 6 ', 6a, 6b and the concave portions 7, 7', 7a, 7b described above, for example, a semicircular or triangular convex portion, a semicircular shape or the like It may be a triangular recess. In any case, as described with reference to FIGS. 4 (a), 4 (b), and 4 (c), it may be a pattern having a different shape fitted for each pipe connection type.
