A derrick structure suitable for a net electric energy storage workover rig
By employing a double-section π-type truss telescopic structure and a multi-dimensional anti-tilt design, the problems of heavy derrick weight and long assembly/disassembly time have been solved, achieving derrick compactness, high load-bearing efficiency, and modular versatility, thus ensuring the safety and stability of the workover rig.

Abstract
本发明涉及石油修井设备技术领域，公开了一种适用于网电储能修井机的井架结构，井架整体为桅型、双节式前开口π型桁架套装伸缩结构，包括井架上体、井架下体、井架底座及天车；井架上体与井架下体构成套装伸缩机构，井架上体底部通过承载块卡座搭接在井架下体顶部的承载块上，井架内部安装有伸缩液压缸，在伸缩液压缸的驱动下使井架上体相对于井架下体伸出或缩回；井架下体的底部与井架底座之间通过井架下体铰支座和底座铰支座配合转动连接。本发明通过套装伸缩设计使结构更紧凑的同时也能大幅降低运输高度，并利用多根绷绳配合铰接支撑，使整个结构在倾斜作业下具备良好的抗侧倾能力与稳定性。
