The invention relates to a derrick traction rope structure, a derrick comprises a vertically-arranged rod body and two rocker arms arranged on the two sides of the rod body, a lifting hook is arranged at the tail end of each rocker arm, and the traction rope structure comprises two first steel wire ropes used for pulling the rocker arms to fluctuate and two second steel wire ropes used for pulling the lifting hooks to ascend and descend. The rod body comprises a first jacking section, a leading-out section and a second jacking section which are sequentially arranged from top to bottom, the axial section of the leading-out section is in an inverted T shape, the leading-out section is larger than the second jacking section, and the leading-out section comprises a plurality of leading-out wheel sets in one-to-one correspondence with the steel wire ropes. Compared with the prior art, the part, corresponding to the rod body, of the steel wire rope is separately designed, the part located at the upper end of the root of the rocker arm is internally arranged, the part located at the lower end of the root of the rocker arm is externally arranged through the leading-out section, and when standard sections need to be increased or decreased, the steel wire rope does not need to be threaded; the efficiency is greatly improved, and meanwhile the service life of the steel wire rope is prolonged.

    本发明涉及一种抱杆牵引绳结构,抱杆包括竖直设置的杆体和设置于杆体两侧两个摇臂,且每个摇臂的末端设有吊钩,牵引绳结构包括两根用于牵引摇臂起伏的第一钢丝绳和两根用于牵引吊钩升降的第二钢丝绳,杆体包括由上至下依次设置的第一顶升节、引出节和第二顶升节,引出节的轴截面呈倒T形,引出节大于第二顶升节,引出节包括多个与各钢丝绳一一对应的引出轮组。与现有技术相比,本发明将钢丝绳对应于杆体部分分开设计,位于摇臂根部上端的部分采用内置式,并通过引出节,在位于摇臂根部下端的部分采用外置式,在第二顶升节因为需要增减标准节时,可以不需要对钢丝绳进行穿线,极大的提高了效率的同时,提升钢丝绳的寿命。
