The excavator hoisting structure comprises two sets of vertically-arranged hanging arms, round holes penetrating left and right are formed in the upper portions of the hanging arms, straight grooves penetrating left and right are formed in the lower portions of the hanging arms in the front-back direction, a cross beam is arranged between the two straight grooves, and a strip-shaped through groove penetrating up and down is formed in the middle of the cross beam; a lifting lug structure is arranged at the through groove and comprises a fixing plate, a lug plate is arranged below the fixing plate, a lifting hole is formed in the lug plate, the fixing plate is larger than the through groove, the lug plate penetrates through the through groove, and a shaft sleeve is further arranged at the round hole. By designing the structures of the hanging arms, the cross beams and the lifting lugs, an existing direct welding connection mode is replaced, the connecting force replaces the welding seam force to adapt to the weight of the beveling machine, and the strength of the whole structure is improved.
本发明公开了一种用于坡口机起吊的挖机吊装结构,包括两组竖直布设的挂臂,挂臂上部开设有左右贯穿的圆孔,挂臂下部设有前后方向布设左右贯穿的直槽,两直槽之间设有横梁,横梁中部设有上下贯穿的条形的通槽,通槽处设有吊耳结构,吊耳结构包括固定板,固定板下方设有耳板,耳板上设有吊孔,固定板大于通槽,耳板穿过通槽,圆孔处还设有轴套。本发明通过设计挂臂、横梁以及吊耳结构,取代现有的直接焊接相连的形式,通过连接力取代焊缝力对坡口机重量的适应,提高了整体结构的强度。
