A monorail traveling spreader for installing boiler equipment in a power plant

Abstract

The invention relates to a single-rail walking lifting device for mounting boiler equipment in a power plant. The lifting device comprises a rail beam, a walking trolley, a beam, an upper lifting lug, a plurality of lower lifting lugs, chain blocks and clamping devices, wherein the walking trolley is arranged on the rail beam; the beam is horizontally arranged below the rail beam, and is spatially perpendicular to the rail beam; the upper lifting lug is arranged above the beam; the lower lifting lugs are arranged below the beam; the chain blocks are fixed on the corresponding lower lifting lugs; the clamping devices are fixed below the chain blocks, are respectively positioned between the corresponding fins, and hook each pipeline on a serpentine pipe screen; the upper lifting lug is fixed below the walking trolley through a lifting ring. According to the device, each clamping device is arranged between the corresponding fins to fix the serpentine pipe screen, so that the condition of damage to the fins in the lifting process can be effectively prevented; during lifting, the chain blocks are used for lifting the serpentine pipe screen, and a plurality of chain blocks are arranged below the beam, so that a plurality of lifting points are formed, and the device is stable and reliable; the serpentine pipe screen can be driven by the walking trolley to longitudinally move to a proper position, so that the efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of slings, in particular to a monorail traveling sling used for installing boiler equipment in a power plant. Background technique [0002] Boiler equipment in thermal power plants is generally designed with serpentine tube panels. The hoisting rigidity of this serpentine tube panel is poor, and it needs to be moved to the installation position after hoisting. Some serpentine tube panels are designed with ultra-thin heat transfer H The fins are generally hoisted by wire ropes at present. The bundled angle of the wire ropes will damage the H-shaped fins of the serpentine tube panel. The original hoisting method is inefficient and more wire ropes are used. Contents of the invention [0003] In order to overcome the deficiencies of the above technologies, the present invention provides a monorail traveling spreader for boiler equipment installation in a power plant that will not damage the H-shaped fins of th...

[0002] Boiler equipment in thermal power plants is generally designed with serpentine tube panels. The hoisting rigidity of this serpentine tube panel is poor, and it needs to be moved to the installation position after hoisting. Some serpentine tube panels are designed with ultra-thin heat transfer H Fins are generally hoisted by wire ropes at present. The bundled angle of the wire ropes will damage the H-shaped fins of the serpentine tube panel. The original hoisting method is less efficient and more wire ropes are used.
