Dismantling method of upper inclined wedge of roller type cold leveling machine

Abstract

The invention particularly relates to a disassembling method for an upper slanting wedge of a roller type cold straightening machine. The disassembling method is characterized by including the following steps that fixing bolts of screwdown cylinders are loosened; the screwdown cylinders are lifted and fixed; fixing pins between locking cylinders and an upper beam are disassembled; the locking cylinders are disassembled by using a traveling crane; connecting bolts between the upper beam and the upper slanting wedge of the cold straightening machine are loosened through a hydraulic spanner; an upper roller system is dismantled, and a hydraulic jack is withdrawn; safety pins between the upper movable beam and the upper slanting wedge are disassembled; the upper beam, the upper slanting wedge and the screwdown cylinders on a roller system trolley are slowly pulled toward the outside of a honorific arch, and all the four screwdown cylinders are lifted away; the roller system trolley is completely pulled out of the honorific arch together with the upper beam and the upper wedge to finish disassembling the upper slanting wedge and the upper beam. The upper slanting wedge of the cold straightening machine is disassembled by the adoption of the steps, and compared with a large-scale disassembling tool manufactured traditionally, the disassembling method for the upper slanting wedge of the roller type cold straightening machine is low in construction cost, safe and reliable and is implemented in a hydraulic-system-free state.

Description

technical field [0001] The invention relates to the field of large-scale equipment disassembly operations, in particular to a method for disassembling oblique wedges on roller-type cold straightening machines. Background technique [0002] With the development of the domestic steel industry, the relocation of steel production lines has gradually become the mainstream of the metallurgy and construction industry. Roller straightening machine is the main process equipment on the thick plate production line, and the structural composition of the wedge-adjusting roller cold straightening machine is relatively special. In the dismantling project, the upper wedge adjustment device is the focus of the dismantling of the wedge adjustment type roller cold leveler. The traditional dismantling method is to first put the roller train into the lower part of the upper wedge through the roll changing hydraulic system, and then pass through four Press down the cylinder to lower the upper mo...

AI Technical Summary

Problems solved by technology

For the safety of dismantling construction, it is necessary to cut off the electrical operation of the relocation equipment. Although this can ensure the safety of dismantling construction, it will make the dismantling of mechanical equipment under special working conditions such as roller cold straightening machines more difficult.
