Horizontal-type-structure repairing equipment for stainless-steel-wrapped vertical column remanufacturing

Abstract

The invention discloses horizontal-type-structure repairing equipment for stainless-steel-wrapped vertical column remanufacturing. The horizontal-type-structure repairing equipment comprises a base, afence, an intermediate-frequency heating pipe, an intermediate-frequency heating pipe position adjusting mechanism, stainless steel wrapping layer lifting supporting frames, a stainless steel wrapping layer axial limiting jacking rod, a vertical column supporting frame, a vertical column pushing hydraulic cylinder and a hydraulic station. The fence is fixedly mounted on the base; the intermediate-frequency heating pipe is hoisted on the intermediate-frequency heating pipe position adjusting mechanism and located in the fence; the stainless steel wrapping layer axial limiting jacking rod, thestainless steel wrapping layer lifting supporting frames, the vertical column supporting frame, the vertical column pushing hydraulic cylinder and the hydraulic station are linearly distributed and arranged in order in the fence; the limiting jacking rod is horizontally and fixedly mounted on the fence; the stainless steel wrapping layer lifting supporting frames, the vertical column supporting frame, the vertical column pushing hydraulic cylinder and the hydraulic station are mounted on the base; the intermediate-frequency heating pipe position adjusting mechanism is located on the outer sideof the fence; the hydraulic station serves as a power source of the vertical column pushing hydraulic cylinder; and a stainless steel wrapping layer flaring mechanism is arranged between the stainless steel wrapping layer lifting supporting frames and the vertical column supporting frame.

Description

technical field [0001] The invention belongs to the technical field of column remanufacturing, in particular to a remanufacturing and repairing equipment for a horizontal structure stainless steel clad column. Background technique [0002] As the core component, the column is used in equipment in various engineering fields, and most of them bear relatively large loads. Because the column has been in a harsh working environment for a long time, such as humidity, coal dust, high sulfur and fluorine, and acid-base special working conditions Under the condition of the column, it will cause the column to corrode and shorten the continuous service period of the column. For this reason, technicians will use stainless steel to cover the column, which can realize the remanufacturing of the column without replacing the column, which not only prolongs the service life of the column, but also saves costs. [0003] At present, when a column is remanufactured with a stainless steel cladd...

Problems solved by technology

[0004] However, the existing stainless steel cladding layer assembly technology needs to be carried out step by step. It is necessary to use an intermediate frequency furnace to heat the stainless steel cladding layer, and then remove the heated and expanded stainless steel cladding layer from the intermediate frequency furnace, and then quickly assemble the column into the stainless steel cladding and the assembly is not complete until the stainless steel cladding cools and shrinks

The above-mentioned assembly process requires manual participation in the whole process. The assembly process is cumbersome and the assembly efficiency and precision are low. Moreover, the size of the intermediate frequency furnace is fixed, and the scope of application to the size of the column is small.
