The invention relates to the technical field of railway engineering, and provides a lifting device, a hoisting system and a loading and unloading method.The lifting device of the high-clearance catenary davit comprises a mounting fixing plate and a lifting mechanism, the mounting fixing plate can be detachably connected to an anchoring part at a davit mounting point, and the lifting mechanism is arranged on the mounting fixing plate; and the lifting mechanism is connected to the bottom surface of the mounting fixing plate and is used for vertically lifting the lifting column. By means of the hoisting system, the problems that in the prior art, after being driven into a structure to be used, an auxiliary anchor bolt cannot be detached and reused, the cost of the auxiliary anchor bolt can be additionally increased in the davit mounting process each time, and a pulley block is directly bound to the auxiliary anchor bolt; and once the pulley block slips off from the auxiliary anchor bolt, a certain safety risk is caused to workers in site construction.

    本发明涉及铁路工程技术领域,提供了一种高净空接触网吊柱的提升装置、吊装系统及装卸方法,所述高净空接触网吊柱的提升装置包含安装固定板和提升机构,所述安装固定板能够可拆卸连接于吊柱安装点处的锚固件,所述提升机构连接于所述安装固定板的底面,所述提升机构用于竖向吊装所述吊柱。使用该吊装系统,能解决现有技术存在的辅助锚栓打入结构中使用后不能将其拆卸下来重复利用,在每次吊柱的安装过程中会额外增加辅助锚栓的成本,滑轮组直接绑在于辅助锚栓上,滑轮组一旦从辅助锚栓上滑脱会对现场施工的工人造成一定的安全风险的问题。
