The two vertical rods 111 are telescopic rods, and the length of each vertical rod can be changed according to the depth of a well, so that the height of the rotary support 1 is adjusted. The cross bar 112 is also formed by coaxially connecting two sections of bar bodies, and the width of the cross bar 112, i.e. the width of the rotating bracket 1, is adjusted by changing the connecting positions of the two sections of bar bodies in the same adjustment mode as the base 3.

The escalator main drive hoisting tool of claim 5, wherein: the two vertical rods are of adjustable telescopic rod structures, and clamps are respectively arranged at the top ends of the two vertical rods and used for clamping the two ends of the rolling shaft, so that the rolling shaft can be fixed at the top ends of the two vertical rods or separated from the two vertical rods.
8. The escalator main drive hoisting tool of claim 3, wherein: the base comprises telescopic mounting panel and the stopper of being fixed in on the mounting panel, the stopper is used for restricting the rotation angle of runing rest orientation and keeping away from main drive direction.
9. The escalator main drive hoisting tool of claim 5, wherein: and the rolling shaft is provided with rollers for matching with the guide rail to run.
10. An operation method of an escalator main drive hoisting tool, comprising the escalator main drive hoisting tool as claimed in claim 2, characterized by further comprising the steps of:
Step one: the preparation stage, dismantling the floor at the side of the escalator to expose a hoistway formed by trusses at the lower layer of the escalator, installing an auxiliary mechanism in the hoistway to support a main drive, installing a base on the trusses at the bottom of the hoistway, and hinging a rotating bracket to the base, so that the rotating bracket can tilt or stand to be vertical to the main drive direction;
Step two: in the lifting stage, the rotating bracket inclines towards the main drive, and a lifting mechanism arranged on the rotating bracket is obliquely tethered to the main drive; the loop chain electric hoist, the rotary support and the auxiliary mechanism form an obtuse triangle structure, and the auxiliary mechanism and the loop chain electric hoist synchronously shrink to enable the main drive to move towards the projection position right below the vertex of the rotary support;
Step three: and in the rotating stage, when the main drive transversely moves to the position right below the vertex of the rotating support, the auxiliary mechanism continues to shrink and separate from the main drive, and at the moment, the main drive avoids the upper structure of the escalator, the rotating support rotates to a vertical state, and the hoisting mechanism continues to shrink to hoist the main drive to the position above the ground.
