EXHAUST PIPE FOR CONSTRUCTION MACHINE, ASSEMBLING METHOD FOR EXHAUST PIPE, AND CONSTRUCTION MACHINE EQUIPPED WITH EXHAUST PIPE
PROBLEM TO BE SOLVED: To provide an exhaust pipe easy to assemble at a predetermined position on a construction machine using the exhaust pipe including a bellows pipe provided in the midway for connecting an engine and an exhaust gas after-treatment device.SOLUTION: An exhaust pipe 7 for the construction machine connects an engine 4 and an exhaust gas after-treatment device 6, including a bellows pipe 71 provided in the midway. In the exhaust pipe 7, a first bracket 31 and a second bracket 32 are provided. When the exhaust pipe 7 is assembled on the construction machine, a temporarily fixing jig 20 is mounted on both brackets 31, 32 across the bellows pipe 71 to establish the state of suppressing the deformation of the bellows pipe 71, and after it is assembled thereon, the temporarily fixing jig 20 is removed from both brackets 31, 32 to establish the state of allowing the deformation of the bellows pipe 71.SELECTED DRAWING: Figure 3
【課題】途中にベローズ管を備えた排気管によってエンジンと排気ガス後処理装置とが接続される建設機械において、所定位置に組付けやすい排気管を提供する。【解決手段】エンジン４と排気ガス後処理装置６とを接続し、途中にベローズ管７１を備えた建設機械の排気管７において、排気管７に第１ブラケット３１及び第２ブラケット３２を設ける。排気管７を建設機械に組付ける時には、両ブラケット３１、３２にベローズ管７１を跨ぐように仮固定用治具２０を取付けてベローズ管７１の変形を抑制する状態とし、組付後は、両ブラケット３１、３２から仮固定用治具２０を取外してベローズ管７１の変形を許容する状態とする。【選択図】図３
