EXTENSIBLE TRUCK FRAME OF CONSTRUCTION MACHINE
To provide an extensible truck frame capable of preventing the phenomenon that sediment accumulated on a guide member enters a slide face to a guide cylinder.SOLUTION: A pair of side frames 16 comprising a crawler 3 are arranged at left/right both sides of a center frame 15 to which an upper structure 5 is connected. Guide members 18 provided at a front and a rear of each side frame 16 are internally fitted into a guide cylinder 17 provided at a front and a rear of the center frame 15 from left and right so as to be slidable. An upper side slide member 19a is made to protrude from an opening of each guide cylinder 17 to outside, and a scratch plate 25 is arranged on its upper face 19a1. A retainer member 27 is arranged at an upper position of the scratch plate 25, and a cylindrical portion 27e extending downward is made to be in contact with the upper face 19a1 of the slide member 19a via a through hole 25b of the scratch plate 25 to be fastened with a bolt 28. A compression spring 29 is interposed between the retainer member 27 and the scratch plate 25, and energized to the slide member 19a side.SELECTED DRAWING: Figure 7
【課題】ガイド部材上に堆積した土砂がガイド筒との摺動面に侵入する現象を防止できる伸縮式トラックフレームを提供する。【解決手段】上部旋回体５が連結されるセンタフレーム１５の左右両側に、クローラ３を備えた一対のサイドフレーム１６を配設し、センタフレーム１５の前後に設けたガイド筒１７内に、各サイドフレーム１６の前後に設けたガイド部材１８を左右から摺動可能に内嵌する。各ガイド筒１７の開口部から上側の摺動部材１９ａを外部に突出させ、その上面１９ａ1に掻き取り板２５を配設する。掻き取り板２５の上方位置にリテーナ部材２７を配設し、下方に延設した円筒部２７ｅを掻き取り板２５の透孔２５ｂを介して摺動部材１９ａの上面１９ａ1に当接させてボルト２８で締結する。リテーナ部材２７と掻き取り板２５との間に圧縮バネ２９を介装し、摺動部材１９ａ側に付勢する。【選択図】図７
