DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rolling roll handling apparatus used in a state of being hung by a crane for gripping and transporting the rolling roll, and more particularly to a rolling roll having no chock. TECHNICAL FIELD The present invention relates to a roll handling device for rolling configured to be able to hold both a roll and a roll with a chock.

[0002]

2. Description of the Related Art Generally, a roll for rolling is mounted on a rolling mill with a pair of chocks mounted thereon for rotatably supporting its rotating shaft. Conventionally, however, the roll is hung by a crane to grip and transport the roll. Rolling roll handling devices used in a state of being held include those that directly grip a rolling roll without a chock and those that grip a rolling roll with a chock through a chock. ing.

A handling device for directly gripping a rolling roll has at least one pair of arms movably suspended from a main body frame, and these arms are driven to move in a phase approaching direction and a phase separating direction. Thus, the rolling roll is gripped from a direction perpendicular to the axis so as to be able to release the gripping. In a handling device that grips a rolling roll with a chock, an engaging pin is provided on each of at least one pair of arms that are movably suspended from a main body frame, and the arms are driven to move in a phase-separating direction. An engaging pin is engaged with an engaging hole formed in a pair of chocks, and a rolling roll is gripped via the chocks.

Japanese Patent Application Laid-Open No. Hei 3-223091 discloses a pair of roll support arms for gripping a rolling roll, regulating the rotation of a chock with respect to the gripped rolling roll, and a rolling roll. A roll lifting device that has a rotating arm mechanism that can rotate a chock by a predetermined angle when polishing or the like, and can grip both a rolling roll with no chock and a rolling roll with a chock from a direction perpendicular to the axis thereof. Is described.

[0005]

However, the conventional rolling roll handling apparatus has a structure in which only one of a rolling roll without a chock and a rolling roll with a chock can be gripped. Depending on the type of roll used, the above two types of roll handling devices need to be replaced with cranes, which increases the work load and greatly reduces the transport efficiency.

On the other hand, in the roll lifting apparatus disclosed in the above publication, the rolling roll is gripped only by the pair of roll supporting arms. Therefore, if the length of the rolling roll is long, the rolling roll cannot be stably gripped. There is a problem, and the versatility for rolls of various lengths is extremely low. The rotating arm mechanism is effective for rotating the chocks, for example, when attaching the rolling rolls with the chocks to the roll grinder. It is desirable to directly grip the chock in order to restrict the pressure and to stably grip.

[0007] In addition to the rolling rolls, a unit-shaped V-roll having a roll body mounted thereon is also incorporated into the rolling mill. However, the roll lifting device is not configured to be able to hold the V-roll, In order to grip and transport, a separate transport unit is required. An object of the present invention is to make it possible to apply both a rolling roll having no chocks and a rolling roll with a chocks in a rolling roll handling device, and to stably grip the rolling rolls having various lengths. Enabling the V-roll to be gripped, and the like.
