FIRE EXTINCTION WORK HYDRAULIC SHOVEL AND FIRE EXTINCTION METHOD
To provide a fire extinction work hydraulic shovel for performing simultaneously, teardown of a building and water discharge in a state in which, an orientation of a water discharge nozzle does not receive an affection of an operation of an attachment of a bucket or a grapple, and a fire extinction method for achieving water discharge from a distance where a human being cannot easily approach, and from a height where a human being cannot easily discharge water, and performing teardown of a fire extinction object if necessary, for water discharge to a fire origin.SOLUTION: There is provided a fire extinction work hydraulic shovel 1 comprising: a water discharge nozzle 30 provided on an arm 22; and a supply pipeline 40 provided on the arm and a boom 21, for supplying water to the water discharge nozzle. The fire extinction method is configured so that, using the fire extinction work hydraulic shovel, a front side of the fire extinction work hydraulic shovel is cooled by water discharge from a wide angle spraying nozzle 32 and fire extinction is performed by water discharge from a rod-state water discharge nozzle 31, and according to necessity, an attachment 23 provided on the fire extinction work hydraulic shovel performs teardown of a fire extinction object 70.SELECTED DRAWING: Figure 4
【課題】放水用ノズルの向きがバケット又はグラップル等のアタッチメントの動作に影響を受けないようにして、建物の取り壊しと放水とを同時に行なうことができる消火作業用油圧ショベルを提供する。また、人が近づくことが難しい距離、及び人が放水することが難しい高さから放水することを可能にするとともに、必要に応じて消火対象物を取り壊して火元に放水することができる消火方法を提供する。【解決手段】アーム２２に設けられた放水用ノズル３０と、アーム及びブーム２１に設けられた、放水用ノズルに水を供給する供給配管４０と、を備えることを特徴とする。また、上記の消火作業用油圧ショベル１を用いて、広角噴霧用ノズル３２からの放水で消火作業用油圧ショベルの前方を冷却しながら、棒状放水用ノズル３１からの放水で消火を行ない、必要に応じて消火作業用油圧ショベルに設けられたアタッチメント２３で消火対象物７０を取り壊すことを特徴とする。【選択図】図４
