[0029] Through the above technical scheme, the clamp 31 is fixedly connected to the side of the sling 32, which is convenient for installing the electric hoist 3 on the outer surface of the flip beam 21. One end of the flip beam 21 is plugged into the upper part of the support frame 18 through the plug-in groove 13, which is convenient for the upper part of the support frame 18 to slide on the outer surface of the flip beam 21.

The first plug-in hole 22 on the surface can be aligned and plugged in. Therefore, after the limiting component 2 is fully unfolded, the two sets of support frames 18 are slid to the two ends for positioning, and the lifting device can be unfolded. Then, the rib plate 11 is pulled to flip upward, and the fastening screw 12 passes through one end of the rib plate 11 and is fastened to the threaded hole 26 at the bottom of the flip beam 21. Then, the clamp 31 is removed, so that the sling 32 is clamped on the outer surface of the flip beam 21, and then the clamp 31 is aligned and clamped with the clamp 31 on the outer surface of the flip beam 21, and then fastened with screws, and the electric hoist 3 can be limited to the outer surface of the limiting component 2. When the escalator is lifted, the electric hoist 3 can be started to lift the escalator. Through the coordinated connection between the supporting component 1, the limiting component 2 and the electric hoist 3, the escalator installation lifting device can have a folding function, which is convenient for transportation and use of the lifting device, and is easy to carry, and can be quickly unfolded and used.
