The invention provides a multifunctional telescopic mast which comprises a multi-stage telescopic rod, a plurality of oil cylinders are arranged in the multi-stage telescopic rod, a pin shaft is fixedly arranged between every two adjacent telescopic rods, an arm head is fixedly arranged at the end of an inner rod of the multi-stage telescopic rod, a winch is fixedly arranged on one side of an outer rod of the multi-stage telescopic rod, and the winch is connected with a lifting hook by winding a steel wire rope around the arm head. An upper in-place sensor is arranged below the arm head, a suspension arm rotating head and a load sensor are arranged on the inner rod, and a lower in-place sensor and a hydraulic clamp are arranged on the outer side of the outer rod; a bearing pin shaft can be conveniently inserted between the rods; the problem that a steel wire rope is needed for bearing when a conventional telescopic mast is lifted or operated is solved; the problem that multiple groups of connecting pipelines are needed in the telescopic process of the telescopic oil cylinder is solved; the boom head is rotated by the boom rotating head, so that the function of centering a wellhead by hoisting a tubular column is realized; the upper position sensor is used for detecting whether a lifting hook retracts, the lower position sensor is used for detecting the pipe column descending distance of a winch, and the load sensor is used for detecting lifting load and inner pipe deformation.

    本发明提供了一种多功能伸缩桅杆,包括多级伸缩杆,多级伸缩杆内设有多个油缸,相邻的两个伸缩杆之间固设有销轴,多级伸缩杆的内杆端部固设有臂头,多级伸缩杆的外杆一侧固设有绞车,绞车通过钢丝绳绕过臂头与吊钩连接,臂头下方设有上到位传感器,内杆上设有吊臂旋转头与载荷传感器,外杆外侧设有下到位传感器与液压钳;便于在杆间插装承载销轴;解决了常规伸缩桅杆起升或作业时需钢丝绳承载问题;解决了伸缩油缸伸缩过程中需要多组连接管线问题;吊臂旋转头旋转臂头,实现吊装管柱对中井口的功能;上位置传感器用于检测吊钩是否收回,下位置传感器用于检测绞车下放管柱距离,载荷传感器用于检测吊装载荷及内管变形量。
