The invention provides a lifting derrick capable of being quickly disassembled and assembled, which comprises a derrick bottom section, a derrick lower section, a derrick middle section and a derrick upper section which are sequentially connected through pins from bottom to top, a balance beam used for being connected with the bottom end of the derrick lower section or the derrick middle section or the derrick upper section is arranged at the top end of a piston rod of the lifting oil cylinder, and a bottom guide rail used for guiding the derrick lower section and the derrick middle section is vertically arranged at the top of the derrick bottom section. Connecting shafts which can be respectively connected with the hooks at the bottom ends of the upper derrick section and the middle derrick section and realize the rotation of the middle derrick section and the lower derrick section in the horizontal direction are arranged on one sides of the top ends of the middle derrick section and the lower derrick section. The derrick installation efficiency is improved, the occupied area needed by derrick installation is reduced, the risk of falling objects from high altitudes is eliminated, and abrasion among all sections of the derrick is avoided.
本发明提供了一种快速拆安的举升井架,包括由下至上依次穿销连接的井架底段、井架下段、井架中段和井架上段,井架底段的下方设置有在竖直方向伸缩的举升油缸,举升油缸的活塞杆的顶端设置有用于连接井架下段、井架中段或井架上段的底端的平衡梁,井架底段顶部竖直设置有用于井架下段和井架中段导向的底部导轨,井架中段和井架下段的顶端一侧均布置有可分别与井架上段和井架中段底端的挂钩连接并实现井架中段和井架下段在水平方向转动的连接轴。本发明产生了提高井架安装效率、减少井架安装所需的占地面积、消除高空坠物的风险和避免井架各段之间磨损的效果。
