<p>PROBLEM TO BE SOLVED: To provide a pipe fixing apparatus which can align pipes when they are connected together. SOLUTION: The pipe fixing apparatus 31 is arranged across a hydraulic pipe 24 at a midpoint thereof, and a base plate 32 of the apparatus 31 is fixed to a base plate mounting beam 18 of a revolving frame 9. The base plate 32 has a bolt hole 32A formed therein, and a retaining plate 33 has a bolt insertion hole 33D formed therein. Then, a fastening bolt 34 is inserted into the bolt insertion hole 33D in the retaining plate 33 to be screwed into the bolt hole 32A in the base plate 32, whereby the hydraulic pipe 24 is rigidly pinched between the base plate 32 and the retaining plate 33. Further, the bolt insertion hole 33D in the retaining plate 33 is formed into a vertically extending long hole. Thus, the insertion location of the fastening bolt 34 in the bolt insertion hole 33D can be vertically adjusted, and therefore the retaining plate 33 is vertically movable with respect to the base plate 32, which aligns the hydraulic pipe 24 with an inflow port 23A of an oil cooler 23.</p> |
