Working machine boom front support and working machine
The invention relates to the field of operation machinery, and discloses an operation machinery movable arm front support and an operation machinery. The bent plate is welded on the inner side plate surface of the side plate connecting part of the two side plates and comprises a bent plate first plate section, and bent plate first plate section welding seams are respectively formed between the two axial ends of the bent plate first plate section and the two side plates; the two outer side flitch plates are welded on the outer side plate surfaces of the side plates and comprise flitch plate rear end parts, on the projection surface perpendicular to the axial direction of the bent plate, the projection of the flitch plate rear end parts covers a first plate section welding seam of the bent plate, and the first plate section welding seam of the bent plate is located between the flitch plate upper edge of the flitch plate rear end parts and the flitch plate first middle edge; a first plate section welding seam of the bent plate and the upper edge of the flitch plate form an acute included angle, the plate thickness of the bent plate is t, and the distance G between the first plate section welding seam of the bent plate and the first middle edge of the flitch plate is larger than or equal to 1.5 t and smaller than or equal to 4 t. The working machine movable arm front support and the working machine structure are high in reliability and long in service life.
本申请涉及作业机械领域，公开了一种作业机械动臂前支承和作业机械，包括：两块侧板；弯板，焊接在两个侧板的侧板连接部的内侧板面上并包括弯板第一板段，弯板第一板段的轴向两端分别与两块侧板之间形成有弯板第一板段焊缝；和两块外侧贴板，焊接在侧板的外侧板面上并包括贴板后端部，在垂直于弯板的轴向的投影面上，贴板后端部的投影覆盖弯板第一板段焊缝，弯板第一板段焊缝位于贴板后端部的贴板上边缘与贴板第一中间边缘之间，弯板第一板段焊缝与贴板上边缘呈锐角夹角布置，弯板的板厚为t，弯板第一板段焊缝与贴板第一中间边缘之间的间距G大于等于1.5t且小于等于4t。本申请的作业机械动臂前支承和作业机械结构可靠性高且使用寿命长。
