Method for fast disassembling and assembling continual-wire-unwinding winding machine

Abstract

The invention relates to a method for fast disassembling and assembling a continual-wire-unwinding winding machine. The method is completed according to the following steps that (1) power supplying of the winding machine is stopped, and a motor, a connecting rod, a band-type brake, a winding-assisting device and an oil supplying pipeline are disassembled; (2) with a lead extrusion method and a coloring method, a gear backlash and a contact area are detected; (3) an upper box is hoisted about 300-400 meters with a chain block and cushioned well with a sleeper, the abrasion condition of a first shaft gear and the abrasion condition of a second shaft gear are inspected, and the upper box is descended; 4) the upper box and a middle box are jointly hoisted about 400-500m with the chain block and a bridge crane, the abrasion condition of a third shaft gear is inspected, and the middle box and the upper box are descended and sealed well; 5) the motor, the connecting rod, the band-type brake, the winding-assisting device and the oil supplying pipeline are assembled back. Compared with the prior art, the method has the advantages of being simple, fast, and high in safety; only the upper box and the middle box are hoisted when the disassembling and the assembling are performed, the workload is effectively reduced, labor intensity is relieved, working efficiency is improved, production cost is reduced, and more economic benefits are created.

Description

technical field [0001] The invention relates to the technical field of cold-rolled silicon steel, in particular to a method for quickly disassembling and assembling a continuous annealing line coiler. Background technique [0002] Cold-rolled silicon steel continuous annealing production line, each line is composed of two coilers that work alternately to ensure continuous production of the annealing line, the continuous annealing line is repaired every two years for about 20 days, and the coiler is composed of three boxes of two-stage reducers The maintenance of the coiler is mainly to detect the wear of the gears and bearings of each shaft and clean the oil pool of the lower box. Lift the upper box and the middle box of the coiler and move them out horizontally, detect the gears and bearings of each shaft, and clean the oil pool of the lower box. Since the two coilers are placed under the continuous annealing furnace, the crane cannot be hoisted to the coiler. During disass...

[0002] Cold-rolled silicon steel continuous annealing production line, each line is composed of two coilers that work alternately to ensure continuous production of the annealing line, the continuous annealing line is repaired every two years for about 20 days, and the coiler is composed of three boxes of two-stage reducers The maintenance of the coiler is mainly to detect the wear of the gears and bearings of each shaft and clean the oil pool of the lower box. Lift the upper box and the middle box of the coiler and move them out horizontally, detect the gears and bearings of each shaft, and clean the oil pool of the lower box. Since the two coilers are placed under the continuous annealing furnace, the crane cannot be hoisted to the coiler, and the chain hoist is used to separate and remove the boxes during disassembly and assembly. The labor intensity is high and the work efficiency is low.
