CANOPY OF WORK MACHINE AND WORK MACHINE PROVIDED WITH THE SAME
PROBLEM TO BE SOLVED: To allow the vicinity of base ends of supporting columns to be effectively reinforced by a simple configuration, to prevent occurrence of excessive stress concentration in base end portions of the supporting columns by vibration generated at the time of traveling and work of a work machine and to impart high rigidity to the supporting columns.SOLUTION: A canopy of a work machine comprises: a base fixed to a machine body; supporting columns rising from the base; a roof provided at upper sides of the supporting columns; and reinforcement members having upper end portions and lower end portions and reinforcing the supporting columns. Outer peripheral surfaces of the supporting columns have first outer surface portions welded to the base and second outer surface portions not welded to the base. The reinforcement members have proximity portions facing the outer peripheral surfaces of the supporting columns and being in close proximity to the second outer surface portions and separation portions facing the outer peripheral surfaces of the supporting columns and being separated from the first outer surface portions so as to avoid interference with the first outer surface portions of the supporting columns. The proximity portions are welded to the second outer surface portions of the supporting columns, and the separation portions are welded to the base.SELECTED DRAWING: Figure 1
【課題】簡易な構造により支柱の基端付近を効果的に補強することができ、作業機の走行時や作業時に生じる振動により支柱の基端部に過大な応力集中が生じることを防ぐ。高い剛性を支柱に対して付与する。【解決手段】作業機のキャノピは、機体に固定されるベースと、ベースから立ち上がる支柱と、支柱の上部側に設けられたルーフと、上端部と下端部とを有し且つ支柱を補強する補強部材と、を備え、支柱の外周面は、ベースに溶接される第1外面部と、ベースに溶接されない第2外面部とを有し、補強部材は、支柱の外周面に対向し且つ第2外面部に近接する近接部と、支柱の外周面に対向し且つ支柱の第1外面部との干渉を回避すべく当該第1外面部から離間する離間部とを有し、近接部は、支柱の第2外面部と溶接され、離間部は、ベースに溶接されている。【選択図】図1
