Boiler furnace overhaul platform adopting M-shaped springboards

Abstract

The invention discloses a boiler furnace overhaul platform adopting M-shaped springboards. The boiler furnace overhaul platform adopting M-shaped springboards comprises a platform main body and lifting equipment; the platform main body comprises main beams, auxiliary beams, folding beams, limiting beams and springboard beams; the M-shaped springboards are flatly laid at the periphery of the platform main body; inner rings of the M-shaped springboards are equipped with fences; the M-shaped springboards comprise springboard platforms and supporting structures arranged below the springboard platforms; the cross sections of the springboard platforms are isosceles-trapezoid-shaped; the supporting structures are mounted at the small ends of the isosceles-trapezoid-shaped springboard platforms, and comprise first supporting structure parts arranged in the middle positions of the springboard platforms; and second supporting structure parts and third supporting structure parts are symmetrically arranged on the two sides of the first supporting structure parts. Therefore, compared with a boiler furnace overhaul platform adopting the conventional springboards, the gross weight is reduced by 9% by adopting the M-shaped springboards, the maximum deformation is reduced to a certain extent, and the boiler furnace overhaul platform adopting the M-shaped springboards is safer.

Description

technical field [0001] The invention relates to a boiler furnace maintenance platform. Background technique [0002] The boiler furnace maintenance platform is an efficient and multi-functional high-altitude maintenance construction tool in the furnace. It replaces the traditional scaffolding, and the platform can be adjusted to the required position for construction work through the operation of the maintenance personnel. It has the characteristics of reasonable structure, convenient use, safety and reliability, high work efficiency, light labor intensity and short maintenance period. It is a stereotyped product widely used in the thermal power industry at present. It can be used for maintenance of various parts in the furnace. Put into use. [0003] Most boiler furnace maintenance platforms are platform structure frames assembled from 2A12 I-shaped aluminum profiles through steel connectors. Up to more than 4 tons. Therefore, for production enterprises, how to reduce th...

Problems solved by technology

[0006] Generally, the maintenance platform is driven by a hoist to complete the lifting operation in the boiler furnace; since the inner diameter of the boiler furnace is generally tens of meters, and the peripheral size of the maintenance platform almost matches the size of the inner wall of the boiler furnace, the area of ​​the maintenance platform is too large. Huge, during the lifting process or the operation process, even if there is a small deviation, its periphery may touch the inner wall of the furnace through the guide wheel; while the installation size of the existing guide wheel on the maintenance platform is relatively fixed and basically cannot be adjusted Therefore, the pulley frame of the guide wheel is easily damaged. At the same time, the direct connection between the guide wheel and the maintenance platform is usually a rigid connection. Therefore, when the guide wheel touches the inner wall of the furnace, it is easy to cause the shake of the maintenance platform and affect the maintenance. platform security
