The invention discloses a folding arm telescopic semi-active compensation crane. The crane comprises a base, a slewing bearing is arranged on the base and connected with a hydraulic slewing mechanism, a tower is arranged on the slewing bearing and connected with a fixed arm, a variable-amplitude oil cylinder set is arranged between the tower and the fixed arm, and a folding arm oil cylinder set is arranged between the fixed arm and a telescopic arm set. A measuring winch, a lifting winch and a telescopic oil cylinder set are further arranged on the telescopic arm set, and a steel wire rope is arranged between the measuring winch and the lifting winch and penetrates through a pulley at the top of the telescopic arm set to be connected with a lifting hook. The telescopic oil cylinder set, the measuring winch, the lifting winch, the folding arm oil cylinder set, the variable-amplitude oil cylinder set and the hydraulic swing mechanism are all connected with a pump station through hydraulic oil ways. The design is ingenious, the storage space is smaller, the crane is stored on a deck, a telescoping boom is a folding arm and recycled, the weight is light, the telescopic suspension arm can be conveniently arranged on the crane, and due to the fact that the steel wire rope winch is adopted, the stroke is controlled by the length of the steel wire rope, and the compensation stroke is larger.
本发明公开了一种折臂伸缩式半主动补偿起重机,包括基座,基座上设有回转支承,回转支承与液压回转机构相连,回转支承上设有塔架,塔架与固定臂相连,塔架与固定臂之间设有变幅油缸组,固定臂与伸缩臂组之间设有折臂油缸组,伸缩臂组上还设有测量绞车、起升绞车与伸缩油缸组,测量绞车与起升绞车之间设有钢丝绳,钢丝绳穿过伸缩臂组顶部的滑轮与吊钩相连,所述的伸缩油缸组、测量绞车、起升绞车、折臂油缸组、变幅油缸组与液压回转机构均通过液压油路与泵站相连。本发明设计巧妙,存放空间较小,吊机在甲板上存放伸缩吊臂为折臂回收,重量轻,并能在吊机上进行方便布置,由于采用钢丝绳绞车,行程受钢丝绳长度控制,补偿行程较大。
