Description

Sector block disassembly tool and disassembly inspection method thereof

Technical Field

The invention belongs to the field of sector block inspection, and particularly relates to a sector block disassembly tool for an uncoiler or a coiler and a disassembly inspection method thereof.

Background

In the cold rolling area, the uncoiler and the coiler are key devices and are respectively responsible for uncoiling a steel coil and processing a steel strip into a coil, the devices are arranged in most of units for continuous production, and even part of the units are provided with double uncoilers and double coiling machines. The uncoiler/coiler mainly comprises main parts such as a sector block, an oblique wedge block, a transmission reduction gearbox and the like, and when the uncoiler/coiler operates for a certain period, relevant parts need to be detected and detected, so that the integrity of the uncoiler/coiler is ensured. The sector block disassembly inspection is an indispensable project, and the sector block is relatively complex in structure and high in matching precision of components, so that the sector block is difficult to disassemble and assemble.

The patent number is CN201510793229.X, the patent name is acid rolling decoiler dabber disintegration overhauls the method of the invention patent discloses when dismantling the sector plate, push out the flange 100mm first, reuse overhaul the travelling crane hang 2 hand block of 1T on the crane hook along the axial direction of dabber to tie up three sector plates, and turn 1# sector plate to the straight below, utilize the crow bar to pry the sector plate to the spindle nose direction, stop when the sector plate is totally disengaged from the expansion sleeve, the loose chain guide point moves the coil of strip dolly to raise the coil of strip that slips and place on the dolly; and (3) descending the trolley by 15mm, binding the rest 2 fan-shaped plates by using a guide chain (hoist), transporting the removed fan-shaped plates out by using the steel coil trolley, inching the mandrel clockwise, rotating the No. 2 fan-shaped plate to the right below, opening the steel coil trolley to the lower part of the mandrel, continuously removing the second and third fan-shaped plates, and after the removed fan-shaped plates are detected and detected, loading the fan-shaped plates back by using the winding trolley. Although the fan-shaped block can be disassembled, the matching surface of the disassembled fan-shaped block is ensured to be upward, and the fan-shaped block can be detected and detected without secondary overturning, when the fan-shaped plate is disassembled, the fan-shaped plate needs to be pried by a crowbar, so that the labor intensity is high, and the pried fan-shaped block is easy to slide down, so that the fan-shaped block is damaged, and even constructors are injured by smashing; moreover, when one sector plate is dismantled, the steel coil trolley needs to carry the sector plate back and forth once, so that the construction efficiency is low; finally, the matching of the sector plate and the inclined wedge block is complex, the sector plate is only assembled back by inching of the winding trolley, the implementation difficulty is high, and the requirement on operators is high.

In addition, since the uncoiler/coiler is often equipped with a hold-down device, the segment is generally located below the hold-down device, the space for mounting and dismounting is limited, and the segment cannot be directly hoisted by using the maintenance travelling crane in the above patent documents. In addition, in the process of assembling and disassembling the fan-shaped blocks, at least 5 hoists need to be hung everywhere, the fan-shaped blocks are hoisted through the hoists, and when the fan-shaped blocks are hoisted to the air, the fan-shaped blocks are easy to slide off, so that constructors are injured by crashing; and in the operation process, the hoists must be matched well to ensure the smooth construction. Because the construction site does not have a special suspension point of a hoist, the situation of outward pulling and inclined hoisting is inevitable, the risk of sliding of the fan-shaped block is further increased, and the construction efficiency is lower. In addition, the sector and the wedge block are complex to match, the dismounting is difficult, and the improvement of the existing sector dismounting method is urgently needed.
