The utility model reduces the process of disassembling and assembling the frame when maintaining the roller shaft of the rolling mill, shortens the time used in the whole maintenance process from the original 13-14 hours to 7-8 hours, greatly reduces the labor intensity, improves the working efficiency, effectively prevents the risk of water leakage caused by the damage of the sealing surface due to the repeated disassembly and assembly of the whole frame, avoids the safety risk of lifting the frame and reduces the labor cost for maintenance.

Description

Disassembling and assembling tool for rolling mill roll shaft

Technical Field

The utility model belongs to the technical field of metallurgy, and particularly relates to a disassembling and assembling tool for a rolling mill roll shaft.

Background

When the rolling mill roll shaft is abnormally maintained, due to factors such as the structure of a rolling mill and the position of the roll shaft, operation courseware is limited, the roll shaft is difficult to disassemble and hoist, the whole rolling mill roll shaft frame is required to be disassembled and then lifted away from a rolling mill area, the roll shaft is disassembled and hoisted in a place convenient for construction, the maintenance labor intensity is increased, the maintenance process is complex, the maintenance process is difficult to maintain in a long time, the original seal is damaged, the potential safety hazard of water leakage in the later stage of equipment is brought, the maintenance process is long in time, the labor intensity is high, and the like, so that the production efficiency is seriously affected.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is to provide a tool for disassembling and assembling a rolling mill roll shaft, which comprises a lever, a welding bin and a knocking plate, wherein the welding bin and the knocking plate are respectively welded at two ends of the lever, the welding bin is provided with a tool screw hole, and the tool screw hole is provided with a connecting bolt matched with the tool screw hole.

Compared with the prior art, the utility model has the following advantages: the process of disassembling and assembling the frame when the rolling mill roll shaft is maintained is omitted, the time used in the whole maintenance process is shortened from the original 13-14 hours to 7-8 hours, the labor intensity is greatly reduced, the working efficiency is improved, the risk of water leakage caused by damage to a sealing surface due to repeated disassembly and assembly of the whole frame is effectively prevented, the safety risk of lifting the frame is avoided, and the maintenance labor cost is reduced.

Drawings

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.

FIG. 1 is a schematic structural diagram of the present invention.

In the figure: 1-lever 2-welding storehouse 3-connecting bolt 4-top screw hole 5-roller 6-strike board 7-frock screw hole.

Detailed Description

Like the dismouting frock of rolling mill roller of fig. 1, it includes lever 1, welding storehouse 2 and strikes board 6, and welding storehouse 2 and strike board 6 are welded respectively at lever 1 both ends, and welding storehouse 2 is equipped with frock screw hole 7, and frock screw hole 7 is equipped with connecting bolt 3 with it matches.

During the use, hoisting equipment lifts by crane near the rolling mill roller through welding storehouse 2, the frock is fixed with the top screw hole 4 of roller 5 through connecting bolt 3, maintenance person utilizes lever principle and the light firm frock lever 1 of mechanics principle, control is balanced, grasp and observe the atress degree, hang roller 5 from the rolling mill frame or install in the rolling mill frame, dismantle welding storehouse 2's connecting bolt 3 again, when dismantling, when roller 5 can't be extracted, adopt suitable hammering strike plate 6, withdraw from roller 5, the dismouting process of roller has just so been accomplished, the fail safe nature of maintenance hoist and mount roller has been guaranteed.

The above embodiments are preferred embodiments of the present invention, and those skilled in the art can make variations and modifications to the above embodiments, therefore, the present invention is not limited to the above embodiments, and any obvious improvements, substitutions or modifications made by those skilled in the art based on the present invention are within the protection scope of the present invention.
