Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carrying device for carrying a coil of a steel wire or the like hung by a hanging tool together with the hanging tool when the coil is immersed in a washing liquid or the like to process the coil.

[0002]

2. Description of the Related Art Conventionally, wire rods such as steel wires can be treated with various treatment liquids such as dipping in an acid bath in order to remove scales, stains and the like caused by processing such as drawing and rolling. Has been done. Such a treatment is performed by immersing the wire rod coil in a treatment liquid stored in a treatment tank in a state of being suspended by a suspender. Here, when it is necessary to perform pickling treatment or cleaning treatment on one wire coil in multiple stages, a plurality of treatment tanks are arranged along a predetermined path, and the treatment is sequentially performed for each tank. To be done. In this case, a rail is provided so as to connect the position directly above each treatment tank, and a self-propelled crane is attached to this rail in a hanging form, while lifting the lifting tool and wire rod coil by the crane, A type of transfer device is used to transfer them between processing tanks.

[0003]

In the transfer apparatus having the above-mentioned structure, a vibration exciter is attached to the crane in order to enhance the efficiency of the pickling process, and vibration is applied to the hanging tool and the coil via a hanging wire or the like. Is being done. However, since the vibration is applied via the suspension wire,
In some cases, sufficient vibration force may not be obtained. Therefore, a gate-shaped frame is provided so as to straddle the processing tanks, and a vibrator is attached to the upper surface corresponding to each processing tank, while a support plate is attached to the upper part of the hanging tool and when the hanging tool is lowered. Attempts have also been made to apply vibration directly to the hanger and coil by applying the support plate to the vibrator from above. However, in this configuration, a vibration exciter is required for each processing tank, and when the suspending tool is pulled up from the processing liquid, the support plate is separated from the vibration exciter, so that vibration cannot be applied to the coil. Therefore, until the treatment liquid attached to the coil surface naturally flows down and decreases, the next dipping treatment cannot proceed, and there is a drawback that the treatment efficiency decreases.

An object of the present invention is to provide a carrier device capable of effectively applying a vibration to a wire rod coil, having a small number of vibrators, and efficiently processing the wire rod coil. It is in.
