BEST MODE FOR CARRYING OUT THE INVENTION As described above, the line tank re-threader device of the present invention is a line tank re-threader device for passing a steel plate through a line tank. A slit pipe provided with a slit for projecting the rope fixing hook is disposed on the inner wall of the line tank such that the slit is directed inward of the line tank, and the main rope is fixed to the slit of the slit pipe. The main rope is pulled into the slit pipe by projecting a main hook, and the main rope is connected to the main rope fixing hook.

Hereinafter, a line tank re-threader of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic perspective view of a line tank re-threader of the present invention.

In FIG. 1, 1 is a line tank,
A slit pipe 2 is provided on the inner wall of the line tank 1.

The line tank 1 includes, for example, a vertical tank used in a continuous production line for cold-rolled steel sheets, but the present invention is not limited to such examples.

The slit pipe 2 provided on the inner wall of the line tank 1 is provided with a slit 5 for protruding a main rope fixing hook 4 provided on the main rope pulling rope 3. Are arranged so as to face inward of the line tank 1.

Examples of the slit pipe 2 include a steel pipe made of stainless steel, general steel, and the like, and a pipe made of a vinyl chloride resin. However, the present invention is not limited to this example. The inner and outer diameters of the slit pipe 2 are not particularly limited, as long as the main rope traction rope 3 can be inserted into the slit pipe 2 with a small sliding resistance. A typical example is a stainless steel slit pipe having an inner diameter of about 10 to 30 mm.

The slit 5 of the slit pipe 2 is oriented inward of the line tank 1 so that the main rope fixing hook 4 provided on the main rope hauling rope 3 is oriented inward of the line tank 1. Is set to

In the line tank re-threader shown in FIG. 1, the slit pipe 2 is disposed below the sink roll 6 so that a steel sheet can be passed under the sink roll 6 below the sink roll. ing.

Next, the main rope traction rope 3 is introduced into the slit pipe 2 such that the main rope fixing hook 4 provided on the main rope traction rope 3 projects from the slit 5 of the slit pipe 2.

The main rope pulling rope 3 can be used without particular limitation as long as it has mechanical strength such as tensile strength that can withstand a load when pulling a steel plate.

As the master rope 10, if the steel sheet 11 has a mechanical strength such as a tensile strength when the steel sheet 11 is passed through the passing roll A8, the sink roll 6, and the passing roll B9 sequentially, it is particularly preferable. It can be used without limitation.

Specific examples of the parent rope 10 include, for example, polyethylene rope, vinylon rope, nylon rope, polyester rope, and the like, but the present invention is not limited only to these examples.

The thickness of the master rope 10 is not particularly limited as long as it can withstand the mechanical strength when pulling the steel plate.

The method of integrating the master rope 10 and the steel plate 11 is not particularly limited. For example, as shown in FIG. 2, the steel plate 11 is inserted into a slit of a plate 13 to which a chain 12 is attached and bent. By the steel plate 11
And the chain 12 are integrated, a hook 14 is provided at the center of the chain 12, and the parent rope 10 is connected to the hook 14.

Thus, according to the line tank re-threader of the present invention, the steel plate can be easily passed through the sink portion in the line tank.

When the line tank re-threader of the present invention is used, a large-scale driving device for raising and lowering the sink roll or the line tank is not required, and
In addition, since it is not necessary to perform the complicated and time-consuming work of draining and filling the liquid in the line tank, when the steel plate is broken or the line is started up with a simple device, it is quickly placed in the line tank of the line, for example. The steel sheet can be passed in a short time of about 4 hours.
