6. The installation and use method of the ceiling beam of the elevator shaft traction overhead telescopic construction hoist according to claim 5, wherein: as the construction height of the storey increases, the construction lifter needs to be lifted to the door opening of the upper storey; the specific process of lifting the construction hoist is that,
the method comprises the steps of temporarily fixing a counterweight on a shaft wall by using a steel tag and a binding steel wire rope through a wall hole left when the shaft wall of an elevator shaft is poured, lowering a car to the bottom of the shaft, loosening a hoisting steel wire rope coiled at the top of the car in advance, disassembling an expansion bolt, reversely rotating a driving socket, shortening the distance between a first nut and a second nut, and enabling a U-shaped clamping head to be separated from the side wall of a door opening of the elevator shaft and downwards rotated by 90 degrees to be in contact with a strut beam; two equal-length hoisting steel wire ropes are used for being hung on four balance lifting lugs, a tower crane is arranged for being firstly lifted to a state that a left telescopic short beam and a support beam are not stressed, a left bolt and a right bolt are pulled out, the left telescopic short beam is pushed into a main beam rightwards and is temporarily fixed by a left bolt, the right telescopic short beam is pushed into the main beam leftwards and is temporarily fixed by a right bolt, and the support beam is horizontally moved into an elevator shaft from a door opening; lifting the construction elevator to the door opening of the upper layer, and repeating the steps (7) - (9);
and then tensioning the hoisting steel wire rope, disassembling the steel tag and the binding steel wire rope which are used for temporarily fixing the weight, and completing heightening and lifting operation after various adjustments are well made.
