Problems solved by technology

[0006] The weight of the equipment to be dismantled and installed this time is about 20t. Only the steam drum weighs about 60t, and the deaerator and initial oxygen tank weigh about 30t. Install 4 electric hoist cranes with a lifting capacity of 10t between the columns in advance to facilitate the installation of the steam drum. The spreader must be able to ensure the synchronization and safety of the lifting and movement of the 12-meter-long steam drum. None of the spreader products on the market can meet the requirements

Abstract

The invention relates to the technical field of mechanical equipment mounting and construction, in particular to a synchronous combined lifting appliance for converter transformation. The synchronouscombined lifting appliance is characterized in that the synchronous combined lifting appliance comprises H-shaped beam rails, trolleys, a transverse connecting support, a winding pulling ring and an electric hoist crane. The two H-shaped beam rails are arranged in parallel and are respectively connected to the bottom of a roof beam. The trolleys are arranged on the H-shaped beam rails and are connected through the transverse connecting support. Each trolley comprises a longitudinal connecting plate, bolts and two wheel frames, wherein the two wheel frames are correspondingly arranged on the two sides of the H-shaped beam rail and are connected with the longitudinal connecting plate through the bolts. A winding pull ring is arranged in the middle of the transverse connecting support. Compared with the prior art, the synchronous combined lifting appliance has the beneficial effects that the structure is simple, the strength is sufficient, a proper electric hoist can be configured according to the weight of equipment to be hoisted, synchronous movement of a plurality of electric hoists can be kept, safety accidents caused by the disengagement of the lifting appliance and a steam drumare avoided, combined use together with equipment like winching equipment is facilitated, and an engineering task is completed.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment installation and construction, in particular to a synchronous combined spreader for converting a converter. Background technique [0002] The main content of the 6# converter environmental protection renovation project in a steelmaking plant is to remove and install all the equipment and pipelines included in the original vaporization cooling system and flue gas purification system of the 6# converter.
