TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to an apparatus for preventing a sideways movement of a loop car mounted with a roll around which a steel strip is wound, and a sideways prevention method using the same.
More specifically, for example, the present invention relates to an apparatus for preventing a loop car from being used in a looper facility for transporting a steel strip used in a steel strip manufacturing line in an iron making process, and a method for preventing a lateral shake using the same.
[0002]
[Prior art]
In the steelmaking process, for example, in a line that continuously produces steel strips such as a cold rolling process or a thin plate manufacturing process, the inlet side of a joining machine that joins coils, or the outlet side of a cutting machine that divides a steel strip. In places where there is a difference in the transport speed of the steel strip, such as before and after a heating furnace or an acid pickling tank, a looper facility for adjusting the transport speed by storing or discharging the steel strip is installed.
There are a horizontal type and a vertical type in this looper equipment, but in the case of a horizontal type looper, as shown in FIG. 1, a transport trolley equipped with a roll wound around a steel strip is installed,
When the loop car repeats running and reverse running, the function of storing and paying out the steel strip can be exhibited.
[0003]
Loop cars are pulled by wires in a direction that resists the tension of the steel strip.They travel by pulling or loosening this wire, so the direction in which the wire is pulled, the offset of the steel strip, and sudden tension fluctuations In some cases, there is a danger that a sideways force will be generated and the loop car will derail.
In view of the above, conventionally, the lateral movement of the loop car has been prevented by installing an apparatus for preventing lateral movement of the loop car from the left and right.
However, recently, in order to improve productivity, the conveying speed of the steel strip has been increasing, and accompanying this, the tension of the steel strip and the weight of the loop car have been increased, so that the loop car has been greatly traversed, There has been a problem that the anti-lateral device is damaged.
Conventionally, various proposals have been made as a device for preventing the traveling vehicle from running down.
[0004]
For example, Japanese Unexamined Patent Publication No. 2000-355275 discloses a tracked bogie system capable of running straight without vibration and smoothly turning a curve by arranging guide rollers so as to sandwich the guide rail. ing.
However, this prior art is directed to a bogie used for a transport device in an automatic warehouse, and when a lateral displacement force from a wire acts, such as a loop car targeted by the present invention, a force acting on a guide roller. And the carriage may be derailed or the anti-sway device may be damaged.
Further, Japanese Patent No. 2531487 discloses a mobile crane in which a lateral guide roller which is in contact with a side surface of a guide rail is installed.
However, in the prior art, the lateral guide roller is directly supported by the bracket, and as in the case of the loop car to which the present invention is applied, the lateral displacement force from the wire, the bias of the steel strip, and the rapid fluctuation of the tension. When repeated, the forces acting on the lateral guide rollers are biased, and the problem that the truck is derailed or the lateral shake prevention device is damaged has not been solved.

An embodiment of the present invention will be described in detail with reference to FIGS.
FIG. 1 is a perspective view illustrating an embodiment of an apparatus for preventing a sideways movement of a loop car according to the present invention.
In FIG. 1, 1 is a loop car, 2 is a steel strip, 3 is a running rail, 4 is a running wheel, and 5 is an anti-lateral shake device.
The steel strip 2 is transported in the direction of the arrow in FIG. 1. In the present embodiment, two rolls are installed on the loop car 1, and the steel strip 2 is wound around the rolls and transported in two reciprocating passes. You.
When the loop car 1 is pulled or loosened by the wire 11 wound around the wire drum 12 on the left side of FIG. 1, the traveling wheels 4 provided at the lower part of the loop car 1 travel on the traveling rail 3.
At this time, the steel strip 2 can be stored by the wire 11 pulling the loop car 1 to the left side in FIG. 1, and conversely, the wire 11 is loosened and the loop car moves to the right side in FIG. Belt 2 can be paid out.
[0010]
Since the tension that the loop car 1 receives from the wire 11 is deviated in the lateral direction, there is a danger that the loop car will run out and be derailed.
FIG. 2 is a plan view illustrating an embodiment of the lower structure of the loop car according to the present invention.
In the present embodiment, for one loop car, four traveling wheels 4 running on the traveling rail 3 are provided, one traveling wheel 4 has no brim, and the other traveling wheel has a brim. This is because there is a bias in the direction of eccentricity due to the direction in which the loop car is pulled, so it is particularly necessary to prevent the side wobbling on one side, and a flange is attached to the wheel on the side that prevents the side wobbling. At a front portion and a rear portion of the wheel, an anti-lateral shake device 5 including a total of eight rollers for horizontally sandwiching the traveling rail is installed. The number of the rollers to be installed may be one between the wheels with a flange, that is, a total of four rollers, depending on the magnitude of the lateral displacement.

Although the brim of the wheel has the effect of suppressing derailment from the side wobbling force of the loop car, the brim rotates with the wheel in the rail direction when suppressing the side wobbling, so if the side wobbling force is large or the brim is shallow, Riding on the rail may cause derailment.
In addition, the thickness of the collar is reduced by abrasion due to friction with the rail, and the strength is reduced.
Of course, the effect of preventing derailment is increased by increasing the number of wheels with a brim, but the above problem occurs.
The anti-lateral wheel according to the present invention has a structure in which the rail is sandwiched from the side, so that it does not derail, and rotates without rubbing against the rail, so that the progress of wear is extremely small.
In the present embodiment, both the conventional wheel with a rim and the side wobbling prevention mechanism of the present invention are provided. There are no restrictions, and all may be wheels without a brim.
