The invention discloses a mounting and dismounting method of a combined lifting appliance for lifting. The problem that a set of lifting appliance cannot be conveniently mounted on I-shaped steel of different specifications is solved. Comprising I-shaped steel, an electric hoist and a U-shaped clamp, the I-shaped steel is transversely fixed in the air, a chain is arranged in the electric hoist, L-shaped clamps are arranged at the two ends of the U-shaped clamp and connected through a telescopic locking mechanism, the device is provided with the telescopic locking mechanism, and clamping of the U-shaped clamp and the I-shaped steel is achieved by rotating a rotary knob. The I-shaped steel clamping device can be suitable for clamping I-shaped steel of different specifications, the device does not need to be frequently replaced, so that the cost expenditure is reduced, the function of being convenient to carry can be achieved by stretching and retracting the L-shaped clamp, portability is improved, the device is further provided with a lock catch mechanism, and the lock catch mechanism is provided with an anti-falling structure and is convenient to disassemble; the falling risk of the electric hoist is reduced, the mounting and dismounting efficiency is improved, the practicability is improved, and meanwhile unnecessary losses are reduced.

    本发明公开了一种起重用组合吊具的安装和拆卸方法,解决了一套吊具不能便捷地安装在不同规格的工字钢上的问题;包括工字钢、电动葫芦和U形夹具,所述工字钢横向固定在空中,所述电动葫芦内设有链条,所述U形夹具的两端设有L型夹具且通过伸缩锁紧机构相连,该装置设有伸缩锁紧机构,通过旋转旋钮来实现U形夹具与工字钢的夹紧,不仅可以适用于不同规格的工字钢的夹紧,无需频繁更换装置,从而降低成本支出,还可以通过伸缩L型夹具来实现便于携带的功能,增加便携性,该装置还设有锁扣机构,该锁扣机构具备防脱落结构并且便于拆卸,不仅降低电动葫芦掉落的风险,而且增加安装与拆卸的效率,增加实用性的同时也降低不必要的损失。
