The invention provides an excavator movable arm front fork structure. On the premise of ensuring the simple and reliable structure, the excavator movable arm front fork structure has the advantages that the structure is light in weight and meanwhile welding marks on the outer surface can be reduced. In order to achieve the technical effects, according to the adopted technical scheme, the excavatormovable arm front fork structure comprises vertical plates, an inner reinforcing plate, a bending plate and an arc-shaped reinforcing plate. The inner arc surface of the arc-shaped reinforcing plateis attached and fixed to outer arcs of the front sections of the vertical plates, and the arc-shaped reinforcing plate is welded and fixed to the vertical plates. The inner reinforcing plate is weldedto the inner side faces of the vertical plates and welded and fixed to the bending plate and the vertical plates. The bending plate is located between the two vertical plates. The inner reinforcing plate and the bending plate have the supporting and reinforcing effects on a front fork. The excavator movable arm front fork structure can be widely applied to the field of excavators.
本发明在保证结构简单可靠的前提下，提供了一种挖掘机动臂前叉结构，能同时兼顾轻量化，减少外表面焊接痕迹，为了解决上述技术问题，本发明采用的技术方案为：一种挖掘机动臂前叉结构，包括立板、内加强板、折弯板和弧形加强板，所述弧形加强板内圆弧面与立板前段外圆弧贴合固定并焊接固定在立板上，所述内加强板焊接在立板内侧面，并与折弯板和立板焊接固定在一起；所述折弯板位于两块立板中间，且所述内加强板和折弯板对前叉起支持和加强作用；本发明可广泛应用于挖掘机领域。
