The invention provides a derrick structure suitable for super single operation and an installation method, the derrick structure comprises a derrick main body capable of being installed on a carrier vehicle, the derrick main body comprises a derrick lower body and a derrick upper body slidably arranged in the derrick lower body, and a telescopic assembly used for pushing the derrick upper body to slide is arranged between the derrick lower body and the derrick upper body; the bottom end of the derrick lower body is provided with a hinge seat hinged to a lug plate at the top of a drill floor through a pin shaft, the thickness of the connecting end of the hinge seat and the derrick lower body is adjustable, and the derrick lower body is provided with an oil cylinder lug used for being connected with the movable end of an oil cylinder used for pushing the derrick lower body to lift on a carrier vehicle. The problem that in the prior art, for stabilizing the center of a wellhead, integral transportation of a derrick and a drill floor has high requirements for the performance of a carrier vehicle and road conditions is solved, and the effects that the stability of the center of the wellhead is improved, the position of the center of the wellhead is adjustable, and the transition efficiency of the derrick is improved are achieved.

    本发明提供了一种适用超级单根作业的井架结构及安装方法,包括可安装于载车上的井架主体,井架主体包括井架下体和滑动设置于井架下体内的井架上体,井架下体和井架上体之间设置有用于推动井架上体滑动的伸缩组件,井架下体的底端设置有通过销轴与钻台顶部的耳板铰接的铰接座,铰接座与井架下体的连接端的厚度可调,井架下体上设置有用于与载车上推动井架下体起升的油缸的活动端连接的油缸耳座。本发明解决了现有技术中存在的为稳定井口中心,进行井架和钻台的整体式运输对于载车的性能以及道路情况要求高的问题,产生了提高井口中心稳定性、实现井口中心位置可调和提高井架的转场效率的效果。
