Description

Technical Field

[0001] The present invention belongs to the technical field of lifting devices, and particularly relates to a decomposable indoor heavy lifting device. Background Art

[0002] During the installation of "current limiting reactors", there are no hoisting facilities indoors. According to the installation requirements of the reactors, the lifting height is 4.5 meters and the lifting mass is 3.5 tons. A device for layered lifting is required. The high layer is lifted to 4.5 meters, and the low layer is then lifted to a height of 2.5 meters and placed on the assembled pillar insulators. The reactors wrap the inner and outer sides of each package layer with 2.0 - 3.0 mm of epoxy fiberglass yarn and lay fiberglass cloth tape. During the coil winding process, each wire is coated with special insulating glue, and the wire and the epoxy layer form a whole. The service life of the reactor mainly depends on the integrity of the body insulation material. Therefore, during the hoisting process, there should be no impact on the outer surface of the reactor, and no external force should be applied to the surface of the reactor coil. The technical requirements are that there should be no damage, rust, or deformation in appearance during production, transportation, and installation. The reactor is a circular electrical device with a diameter of 1.7 meters, and the hoisting position is on a pentagonal structure inside the circle. Measures should be taken to ensure hoisting stability, and the hoisting facilities should have high strength. Elastic hoisting facilities will cause gravitational inertia inside the hoisting, resulting in crack deformation of the coil and the internally designed hoisting aluminum plate. Special personnel should be assigned to command the handling to ensure personal and equipment safety. In order to achieve stable and rigid hoisting facilities for hoisting work, this device is designed. Summary of the Invention

The sliding hoisting component includes a pulley bolt. There are four pulley bolts, and a pulley hoisting plate is arranged in the middle of two of the pulley bolts. Pulley side plates are arranged at both ends of the pulley bolts, and pulley wheels are arranged near the pulley side plates at both ends of the pulley bolts. A support fixed sleeve is fixedly connected to the top end of the support, and the support is connected to the sliding rod through the support fixed sleeve.

[0006] Both the support and the bracket vertical frame are provided with support lifting rings.

[0007] Screw holes are opened on the bracket bottom support, and the number of screw holes is four. Stand bottom support positioning bolts are threadedly connected in the screw holes.

[0008] The number of the supports, bracket vertical frames, and bracket bottom supports is two.
