Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of power plant steel structure, and particularly relates to a disc structure for turning over of a steel structure stack beam of a power plant. BACKGROUND

[0002] In large thermal power plants, nuclear power plants and other industrial facilities, super-heavy and super-long H-shaped steel stack beams are widely used in key parts such as main plant buildings and boiler steel structures due to their excellent bearing performance. Such stack beams are composed of multiple H-shaped steel segments welded or bolted together, and are large in size (tens of meters long and hundreds of tons heavy). During manufacturing, transportation or installation, they need to be accurately turned over by 180 degrees to meet process requirements, adjust posture or weld seams at the bottom.

[0003] Currently, the turning over of large stack beams mainly relies on special disc structures, which are temporarily fixed on the flange plates by welding, and are used in combination with traveling cranes or hoisting equipment to achieve smooth turning over. However, as stack beams tend to be super-heavy and super-long, the limitations of existing technologies become apparent. First, the lifting capacity of traveling cranes is insufficient. The conventional disc needs to be lifted together with the component by the traveling crane. The total lifting load of the hundreds of tons of stack beams often exceeds the rated capacity of the equipment, resulting in limitations in the manufacturing and turning over of large components, making it difficult to carry out on-site operations, and restricting efficiency and flexibility. Second, the welding and disassembly process is complicated. Although full penetration welding is reliable in strength, it is time-consuming and requires high standards, which can affect the performance of the base material due to the heat-affected zone and residual stress. Gas cutting or carbon arc gouging is required for disassembly, which can easily damage the base material. Subsequent polishing is time-consuming and causes material waste, seriously delaying progress.

[0004] Therefore, there is an urgent need to innovate the turning over disc structure to ensure safe turning over while achieving rapid disassembly, reducing the load on the traveling crane, reducing damage to the base material, and improving operational efficiency. SUMMARY

[0005] The technical problem to be solved by the present application is to provide a disc structure for turning over of a steel structure stack beam of a power plant, which solves the technical problem of the existing turning over disc structure that cannot be used repeatedly and is time-consuming and laborious to weld and polish when in use.

[0008] Further, the connecting piece comprises a bottom plate B which is attached to the top surface of the flange plate of the nesting beam type steel, and a rolling plate B which is vertically welded on the bottom plate B; the rolling plate B is detachably connected with the rolling plate A through a connecting plate, the two side edges of the rolling plate B are straight edges, the top edge of the rolling plate B is an arc-shaped edge, and the arc-shaped edges of the top edge of the rolling plate B and the other side edge of the rolling plate A are smoothly connected and jointly form a semicircular arc-shaped edge.

[0009] Further, at least one row of threaded holes A are arranged on the side of the rolling plate A which is close to the straight edge, at least one row of threaded holes B are arranged on the side of the rolling plate B which is close to the straight edge, and threaded holes C which are adapted to the threaded holes A and the threaded holes B are arranged on the connecting plate, and the connecting plate is detachably connected with the rolling plate A and the rolling plate B through bolts.

[0010] Further, a plurality of connecting pieces are connected between the two clamping pieces, and the connecting pieces are arranged in parallel between the two clamping pieces, and the rolling plate A and the rolling plate B, and adjacent rolling plates B are detachably connected through the connecting plate.

[0011] Further, the clamping hook comprises a hooking connecting plate and a hooking plate which is in an integral structure with the hooking connecting plate, the hooking connecting plate is welded on the top surface of the bottom plate A, and the hooking plate and the bottom surface of the bottom plate A form a hooking groove which is adapted to the side edge of the flange plate of the nesting beam type steel, and the side edge of the flange plate of the nesting beam type steel is embedded in the hooking groove.

[0012] Further, two clamping hooks are welded on the bottom plate A of the clamping piece, and the two clamping hooks are symmetrically arranged on the two sides of the rolling plate A.

[0013] Further, a reinforcing plate is welded between the rolling plate A and the bottom plate A.

[0014] Compared with the prior art, the present application has the following beneficial effects: The present application has the following beneficial effects:

[0015] The present application does not need to be welded to the body of the component, and eliminates the welding operation and the subsequent necessary polishing cleaning process in the traditional method, directly simplifying the overall process flow.
