The invention discloses a heavy sinking derrick for ultra-deep vertical shaft construction. A head sheave platform comprises a front side edge beam, a side surface edge beam, a middle beam and a movable beam; the front side edge beams located on the front side and the rear side and the two side face edge beams located on the left side and the right side are distributed in a rectangular mode and fixedly connected to form a rectangular frame structure, and the two ends of the two middle beams are fixedly connected with the middles of the two side face edge beams respectively. The four movable beams are vertically arranged at the left parts and the right parts of the upper ends of the front side beams and the middle beams; each movable beam is connected with the front side beam and the middle beam through a movable connecting structure; the four bevel angle columns are uniformly distributed below the head sheave platform in the circumferential direction; an M-shaped assembly, an upper transverse supporting piece, a W-shaped assembly, a lower transverse supporting piece and a splayed assembly are sequentially and fixedly connected between every two adjacent bevel angle columns from top to bottom. The four corner column bases are fixedly connected to the lower ends of the four bevel angle columns respectively. The derrick can flexibly meet the operation requirement of oversized working load suspension in the construction process of an ultra-deep vertical shaft.
一种超深立井施工用重型凿井井架,天轮平台包括正面边梁、侧面边梁、中间梁和活动梁;位于前后两侧的正面边梁与位于左右两侧的两根侧面边梁呈矩形地分布,并固定连接形成矩形框架结构,两根中间梁的两端分别与两根侧面边梁的中部固定连接;四根活动梁垂直地布置在正面边梁、中间梁上端的左部和右部;每根活动梁与正面边梁、中间梁之间均通过活动连接结构进行连接;四根斜角柱周向均匀地分布在天轮平台的下方;相邻两根斜角柱之间由上到下依次固定连接有M形组合件、上横向支撑件、W形组合件、下横向支撑件和八字形组合件;四个角柱座分别固定连接在四根斜角柱的下端。该井架能灵活地满足超深立井井筒施工过程中悬吊超大工作荷载的作业需求。
