Compared with prior art, the beneficial effect of the present invention is:

1. When the first leg and the second leg of the outer lifting frame are fixed on the steel structure beam, the hydraulic rod cylinder drives the inner lifting frame to push upward. After reaching the position, the inner lifting frame is fixed on the beam through the third and fourth legs. The four telescopic platforms on the workbench can be stretched out for operation as needed. Secondly, when the operation is completed, the first leg and the second leg of the outer lifting frame are retracted, and the hydraulic rod cylinder drives the outer lifting frame to be pulled up, and the positions of the inner and outer lifting frames coincide. At this time, the outer frame passes through the first leg and the second leg fixed. In this way, through the cooperation of the hydraulic cylinder rod, the outer lifting frame is fixed first, and then the inner lifting frame is pushed out. After the operation is completed, the inner lifting frame is fixed, and the outer lifting frame is pulled upwards. The device itself climbs step by step.

2. When the whole device needs to move downward, fix the inner lifting frame and lift the outer frame downward. After the work is completed, fix the outer frame and retract the inner frame downward.

3. During the climbing process, when the inner lifting frame moves upwards, the four telescopic platforms need to be retracted, and when the outer lifting frame is pulled upwards, the four telescopic platforms do not need to be retracted. During the descent, when the outer lifting frame moves downwards, the four telescopic platforms need not be retracted, and when the inner lifting frame moves downwards, the four telescopic platforms need to be retracted.

4. Through the cooperation of the outer lifting frame and the inner lifting frame, the stable fixing of multiple positions is realized. During construction, it can rise or fall freely; the four telescopic work platforms can be extended independently, which is convenient for the construction of the steel structure of the elevator. It is also convenient for workers to install exterior walls and curtain walls at the same time to achieve wider field operations; the lifting construction platform climbs up step by step from the inside of the elevator shaft to avoid occupying the construction space outside.

5. It avoids the problem of installing a lift on the outside for operation, requiring separate construction on four sides, high risk factor and low efficiency. At the same time, it can realize end-by-end upward construction, and the construction is more convenient.
