DEVICE FOR PREVENTING BUSH OF HYDRAULIC SHOVEL FROM BEING PULLED OUT
PROBLEM TO BE SOLVED: To provide a device for preventing a bush from being pulled out which is used when a work tool of a hydraulic shovel is detached, which prevents a bush from being pulled out of a bearing device, and which can maintain a tip portion of a linkage.SOLUTION: A device 30 for preventing a bush from being pulled out is applied to a hydraulic shovel 1 comprising: an arm side bearing device 16A supporting a work tool connecting pin 14A connecting an arm 7 and a bucket 9; and a link side bearing device 16B supporting a work tool connecting pin 14B connecting a linkage 10 and the bucket 9. The device 30 is used in a state where the bucket 9 is detached from the work tool connecting pins 14A, 14B. The device 30 for preventing a bush from being pulled out comprises: an arm side cylindrical body 31A covering the circumference of the work tool connecting pin 14A protruding from the arm side bearing device 16A; a link side cylindrical body 31B covering the circumference of the work tool connecting pin 14B protruding from the link side bearing device 16B; and a plate 32 connecting the arm side cylindrical body 31A with the link side cylindrical body 31B.SELECTED DRAWING: Figure 6
【課題】油圧ショベルの作業具を取外した状態で使用されて、軸受装置からのブッシュの抜け出しを防止し且つリンク機構の先端部を保持することができるブッシュ抜け止め装置を提供する。【解決手段】ブッシュ抜け止め装置３０は、アーム７とバケット９を連結する作業具連結ピン１４Ａを支持するアーム側軸受装置１６Ａと、リンク機構１０とバケット９を連結する作業具連結ピン１４Ｂを支持するリンク側軸受装置１６Ｂとを備えた油圧ショベル１に適用され、作業具連結ピン１４Ａ，１４Ｂからバケット９を取り外した状態で使用される。ブッシュ抜け止め装置３０は、アーム側軸受装置１６Ａから突出した作業具連結ピン１４Ａの外周を覆うアーム側円筒体３１Ａと、リンク側軸受装置１６Ｂから突出した作業具連結ピン１４Ｂの外周を覆うリンク側円筒体３１Ｂと、アーム側円筒体３１Ａとリンク側円筒体３１Ｂを連結するプレート３２とにより構成される。【選択図】図６
