The invention relates to the field of engineering machinery, in particular to a steel wire rope guide structure of a rotary drilling rig. The steel wire rope guide structure comprises a crawler chassis, a winch, a four-bar linkage structure, a power head, a mast, a crown block and a drill rod, wherein the crown block is arranged at the top of the mast, the four-bar linkage structure comprises three supporting oil cylinders and a triangular supporting arm, the three supporting oil cylinders are connected with the triangular supporting arm correspondingly to form the four-bar linkage structure, and the triangular supporting arm and the three supporting oil cylinders are further connected with the crawler chassis and the mast respectively; and the steel wire rope guide is characterized by further comprising a guide wheel, the guide wheel is arranged on the triangular support arm, and steel wire rope sequentially penetrates through the winch, the guide wheel and the crown block to be connected with the drill rod. According to the steel wire rope guide structure, the guide wheel is arranged on the triangular supporting frame instead of being arranged on the mast traditionally, so that the load of the mast in the horizontal direction is reduced, and the stability of the mast is improved.

    本发明涉及工程机械领域,具体是一种旋挖钻机的钢丝绳导向结构,包括履带底盘、卷扬机、四连杆结构、动力头、桅杆、天车,钻杆;其中,天车设置在桅杆的顶部,四连杆结构包括三根支撑油缸和三角支臂,该三根支撑油缸分别与三角支臂连接并形成四连杆结构,该三角支臂和三根支撑油缸分别还与履带底盘和桅杆连接;其特征是:还包括导向轮,所述导向轮设置在三角支臂上,钢丝绳依次穿过卷扬机、导向轮和天车而与钻杆连接。本钢丝绳导向结构将导向轮从传统的设置在桅杆上移到了三角支撑架上,从而减轻桅杆在水平方向的载荷,增加了桅杆的稳定性。
