The invention belongs to the field of steel wire rope pulling of cranes, and particularly relates to a pulling fiber jacking device which comprises a supporting assembly and an adjusting assembly, and the supporting assembly is in sliding fit with a steel wire rope and used for supporting the steel wire rope; the adjusting assembly is connected with the supporting assembly and used for adjusting the supporting position of the supporting assembly. The boom is used as a main bearing component of the crane, a hoisting mechanism used for winding and unwinding a steel wire rope is arranged at the boom tail of the boom, a hook pulley is arranged at the boom head of the boom, and the steel wire rope on the hoisting mechanism needs to be pulled to the boom head from the boom tail by an operator and penetrates through the hook pulley. The hoisting mechanism and the steel wire rope are used for stretching and bearing the lifting hook pulley, so that an object is hoisted. In the fiber pulling process, the steel wire rope can make contact with the arm frame due to the gravity of the steel wire rope, the steel wire rope is supported upwards through the supporting assembly, the steel wire rope and the arm frame are separated in the fiber pulling process, and then the steel wire rope is prevented from abrading the arm frame.
本申请属于起重机的钢丝绳拉纤领域,具体地涉及一种拉纤顶升装置,包括支承组件和调节组件,其中,支承组件与钢丝绳滑动配合并用于支承钢丝绳;调节组件与支承组件连接并用于调节支承组件的支承位置。臂架作为起重机的主要承重构件,臂架的臂尾处设有用于收放钢丝绳的卷扬机构,臂架的臂头处设有吊钩滑轮,卷扬机构上的钢丝绳的需由作业人员从臂尾拉纤至臂头并穿设在吊钩滑轮中,通过卷扬机构和钢丝绳来对吊钩滑轮起到拉伸承载作用,从而实现对物品的吊装。在拉纤过程中,钢丝绳由于自身重力会与臂架接触,在本申请中,通过支承组件来向上支承钢丝绳,在拉纤的过程中分离钢丝绳和臂架,进而避免钢丝绳磨损臂架。
