This invention discloses a construction method for controlling the construction alignment and overturning resistance of a type A cable tower, comprising the following steps: preliminary preparation; design, verification, and evaluation of the cable tower's anti-overturning combined control system, which includes a cable tower hollow column construction alignment combined control system formed by connecting the tower column stiffening frame system and the anti-overturning system, a multi-level horizontal active cross bracing system, and a prestressed concrete upper crossbeam system. This system resists the overturning force generated by the upward suspended construction of the hollow tower column through the cable tower hollow column construction alignment combined control system. Combined with the synergistic effect of the horizontal active cross bracing system and the prestressed concrete upper crossbeam system, it jointly offsets the inward tilting force generated by the self-weight and construction load of the two limb tower columns during construction, thereby balancing the tower column overturning moment and ensuring that the cable tower alignment, inward tilting force, and tilt angle meet design requirements. The method also includes the following steps: dynamic control analysis of the spatial position of the cable tower column construction segments; construction and dismantling of the cable tower anti-overturning combined control system.

The utility model relates to the technical field of transformer maintenance, and particularly discloses a lifting maintenance platform for a large transformer. The maintenance platform comprises two sets of stand columns arranged in parallel in the Z-axis direction, a folding supporting platform which is in sliding fit with the stand columns and ascends and descends in the Z-axis direction, a lifting mechanism installed on the stand columns and used for controlling the folding platform to ascend and descend in the Z-axis direction, and a non-return mechanism installed on the stand columns and used in cooperation with the folding supporting platform. According to the utility model, the problem that power-assisted lifting equipment such as electric or hydraulic lifting equipment cannot be erected during overhaul and maintenance operation of a large transformer in a narrow space is effectively solved, and the overhaul efficiency is greatly improved.
