Abstract

PURPOSE:To correctly and surely load not only a regular roll with chock but also a non-symmetrical dissimilar roll in the longitudinal direction of the roll or in the radial direction by providing on each end part of the roll body a stepped part to be supported by a receiving table in a concentrical manner with the roll axis. CONSTITUTION:A stepped part 4 to be supported by a roll receiving part 11 of a roll receiving table device 10 is formed in the end surface of a roll body 2. This supported stepped part 4 is formed from the end surface of the roll body 2 to be larger than the width of the roll receiving part 11 of the receiving table 10 so that the roll may be stably loaded by the roll receiving part 11 of the receiving table 10, and at the same time, and the diameter of the section is formed in a concentrical manner with the roll axis from the viewpoint of the precision of the loading position that the roll body 1 is horizontally loaded. In order to simplify the loading, the distance of this supported stepped part from the roll axis is made constant over the whole roll, and the distance between the supported stepped parts at both end parts is preferably constant.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to placing a rolling roll on a pedestal when attaching or detaching the roll chock.

[0002]

2. Description of the Related Art When a roll chock of a chock built-in roll is attached or detached, the roll is hung by a rope or a special suspending device and conveyed to and placed on a roll cradle of a chock attaching / detaching device.

At this time, since the position of the hanging roll becomes unstable, the crane operation requires a lot of manual labor such as manual hanging work.

A device for accurately positioning the hoisting roll by a crane to carry it in and out of the cradle or to take it out of the cradle without the need for manual labor is disclosed.
It is disclosed in Japanese Patent Application Laid-Open No. 7-156819 and Japanese Patent Application Laid-Open No. 62-292207.

However, conventionally, the supporting points of the rolls to be placed on the pedestal at the time of attaching and detaching the chocks are usually both end portions of the roll body, and particularly, like the rolls for continuous rolling of rail material, For rolls whose shape in the longitudinal direction and radial direction of the roll surface is not symmetrical, the supporting point is different, and the diameter of the supporting point is also different on the left and right, so when mounting the roll on the pedestal, It took time and effort to keep the shaft horizontal.

[0006]

SUMMARY OF THE INVENTION According to the present invention, not only an ordinary roll with chocks but also a deformed roll which is asymmetric in the radial direction in the longitudinal direction of the roll can be placed accurately and reliably. To provide the means for doing so.

[0007]

SUMMARY OF THE INVENTION In order to achieve the object, the present invention is a roll structure for placing a roll chock of a rolling roll on a pedestal when attaching and detaching the roll chock.
A stepped portion supported by a pedestal is provided at both ends of the roll body coaxially with the roll axis.

The stepped portion may be formed in a circular shape having a concentric cross section with respect to the roll shaft, but the stepped portion may have an arbitrary cross section corresponding to the receiving surface of the mounting pedestal. Can also be

Further, by standardizing the formation of the support step portions on both ends of the main body of the all-type roll and forming the support step portion at a constant distance from the roll axis, the object is more conveniently achieved. .

[0010]

[Operation] No need for fine adjustment of the pedestal in the vertical direction,
By adjusting only the distance between the pedestals according to the length of the working surface of the rolls to be placed, the roll axes can be installed in a reliable parallel state by simply suspending the rolls in the receiving section and transferring. can do.

[0011]

1 and 2 show a state in which the roll of the present invention is placed on a pedestal.

FIG. 1 is a view seen in the longitudinal direction of the roll,
FIG. 2 shows a view of the receiving portion of the roll as seen from the axial direction.

In these figures, 1 is a roll body 2
Shows a roll with chocks 3 at both ends. On the end surface of the roll body 2, the roll receiving portion 11 of the roll receiving device 10 is provided.
A step portion 4 supported by is formed.

The support step portion 4 extends from the end surface 5 of the roll body 2 to the roll receiving portion 11 of the receiving table 10 so that the roll can be stably placed on the roll receiving portion 11 of the receiving table 10.
The width of the cross section is preferably concentric with the roll axis in view of the accuracy of the mounting posture that the roll main body 1 must be mounted horizontally. .

Further, in order to simplify the loading work, the supporting step portion 4 has a constant distance from the roll axis over all rolls, and the intervals between the supporting step portions 4 at both ends are constant. It is desirable to do.

The cross-sectional shape of the support step portion 4 is not limited to a circular shape, and can be formed in any shape such as a square or a hexagon.

As described above, the roll body 1 having the support step portion 4 formed near the end face thereof is supported by the pedestal device 10 having the roll receiving portion 11.

The pedestal device 10 has a frame 12 installed on the ground, and a pair of receiving liners 13 is provided on the upper surface of the frame 12, on which the roll step 4 is placed. A roll receiving portion 11 is provided. Further, both roll receiving portions 11 can be supported by roll receivers whose intervals can be adjusted according to the length of the rolls placed thereon.

Reference numeral 14 denotes a moving mechanism for moving both roll receiving portions 11, which is a roll receiving portion drive device as a moving mechanism, and is a driving device such as a hydraulic cylinder, an air motor, a hydraulic motor, an electric motor, an air cylinder or the like. The roll receiving portions 11, 1 arranged at both ends of the roll.
The distance between the rolls 1 can be adjusted according to the length of the roll to be placed.

In the above-mentioned embodiment, the case where the roll receiving step portion 4 is a concentric circle has been described, but the roll receiving step portion may have an arbitrary cross-sectional shape corresponding to the mounting table. Good.

The position of the roll receiving surface of the roll receiving step may be standardized so as to be constant from the roll axis of the all-type roll.

[0022]

According to the present invention, the following effects can be obtained.

(1) The roll receiver can be fixed by unifying the diameter and axial position of the roll receiver, and no adjustment is required.

(2) Since the standardized receiving portion is formed on the end surface of the roll body, it is necessary to adjust the receiving member of the roll receiving device in accordance with the roll length in the radial direction. The roll can be placed parallel to the roll axis without doing so.

(3) Therefore, the roll receiving device does not require fine adjustment equipment for the receiving member, and the work of the device can be simplified and speeded up.

(4) Further, since the work of attaching and detaching the roll chock is simplified, there is no fear of damaging the roll shaft or the like.

Since the side surface of the step (5) can be used as a roll misalignment stopper in the roll axial direction when the chock is attached or detached, another roll misalignment prevention device is not required.
