BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protection mechanism for a cable carrier which connects an induction heating device which traverses toward the center of a line and a supply source for supplying electric power, water and the like thereto.

[0002]

2. Description of the Related Art Generally, in a steel rolling line, when a material to be heated is continuously run and rolled, both ends of the material to be heated having a large temperature drop are heated by induction heating immediately before a rolling mill to obtain a uniform temperature. And then rolling. In this induction heating device, for example, as shown in FIG. 1, inductors 2 and 2 are attached to the ends of arms 1 and 1 projecting up and down in two stages so as to face up and down. The magnetic flux penetrates the material 3 to generate an interlinking eddy current in the material to be heated 3 to perform induction heating.

In this induction heating apparatus, arms 1 and 1
The tip of the inductor 2, 2
, And the rear end side can be moved up and down by hydraulic cylinders 5 and 5 or electrically driven. A motor 6 is mounted on the inside of the main body of the apparatus. The motor 6 is connected to wheels 7 provided on the bottom. The motor 6 travels on rails 8 arranged perpendicular to the rolling line to change the plate width of the material 3 to be heated. It can be moved sideways in response to

In this induction heating apparatus, as shown in FIG. 2, for example, the induction heating apparatus moves from a standby position to an operation position, and is supplied by a flexible cable carrier 11 by connecting a number of links 10. The source side and the induction heating device are connected to each other, and the cable carrier 11 is supplied to the induction heating device through a power supply cable 12 and a cooling water hose 13.

However, as shown in FIG. 2, when the induction heating device is retracted, the cable carrier 11 projects on the rolling line, and the radiant heat from the material to be heated 3 which is heated to about 1100 ° C. directly hits the rubber. There is a problem in that the power supply cable 12 and the cooling water hose 13 covered with the heat are heated and the rubber coating is damaged.

[0006]

SUMMARY OF THE INVENTION The present invention eliminates the above-mentioned drawbacks, and prevents power supply cables and cooling water hoses from radiating heat of the material to be heated, thereby preventing heating of the rubber coating and improving durability. A cable carrier for a heating device is provided.

[0007]

SUMMARY OF THE INVENTION According to the present invention, there is provided an induction heating apparatus in which links are mounted on both sides of a clamp plate for supporting a power supply cable and a cooling water hose through the pins, and the links are rotatably connected by pins. In the cable carrier of the device, press pins are provided horizontally along the clamp plate at intervals on the outer peripheral side of the clamp plate of the clamp plate, and both sides of the press pins are rotatably supported by penetrating the link. A belt-like protective cover is inserted between the holding pin and the clamp plate, and both ends of the protective cover are connected to ends of the cable carrier.

[0008]

The induction heating apparatus of the present invention moves the material to be heated to the rolling line side in accordance with the width of the material to be heated, and performs induction heating by sandwiching both ends of the material to be heated from above and below with inductors. The inductor is supplied with electric power and cooling water through a power supply cable and a cooling water hose supported by a flexible cable carrier. In this induction heating state, the radiant heat from the material to be heated is shielded on the distal end side of the cable bear.

When the material to be heated is not heated by the induction heating device, the material is retracted and made to stand by. In this state, the radiant heat from the material to be heated which is heated at a high temperature while the cable carrier protrudes above the rolling line is directly applied. Since a strip-shaped protective cover is provided between the clamp plate and the holding pin on the outer periphery of the cable carrier, radiant heat from the material to be heated is blocked here, and the inner power supply cable and cooling water hose are heated. Can be prevented. In addition, the protective cover is supported in the gap between the clamp plate and the holding pin in a free state, and only the both ends are fixed, so the position of the clamp plate and the protective cover are relatively shifted in the curved part of the cable carrier. Is available.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to FIGS. As shown in FIGS. 4 and 5, the cable carrier 11 has insertion holes 14 through which the power supply cable 12 and the cooling water hose 13 are inserted, and links 10 on both sides of a clamp plate 15 for supporting these. The links 10 are mounted at right angles to each other, as shown in FIG.
Are connected rotatably. The clamp plate 15
Pressing pins 17 are provided horizontally along the clamp plate 15 at intervals on the outer peripheral side of the cable carrier, and both sides of the pressing pins 17 are rotatably supported by penetrating the links 10, 10. Further, a band-shaped protective cover 18 made of a non-magnetic material such as stainless steel, copper, or brass is inserted between the holding pin 17 and the clamp plate 15 so that both ends of the protective cover 18 are connected as shown in FIG. It is connected to fixtures 19, 19 attached to the end of 11. 20 is a cable bear
11 is a fixed end, and 21 is a movable end.

As shown in FIG. 1, the induction heating apparatus having the above structure drives a motor 6 corresponding to the width of the material 3 to be heated, moves the rail 8 on the rolling line side, and moves the material 3 to be heated. Is heated by induction between both ends of inductors 2 and 2 from above and below. Power and cooling water are supplied to the inductor 2 through a power supply cable 12 and a cooling water hose 13 supported by a cable bear 11. In this induction heating state, the distal end side of the cable bear 11 is supported by the support plate 9 and the radiant heat from the material to be heated 3 is shielded here.

When the end of the material to be heated 3 is not heated by the induction heating device, it is retracted and put on standby as shown in FIG. When the induction heating device is retracted, the cable bear 11 projects from the support plate 9 onto the rolling line, and the radiant heat from the material to be heated 3 which has been heated at a high temperature is directly applied. However, a belt-like protective cover 18 made of a non-magnetic material is provided between the clamp plate 15 and the holding pin 17 on the outer peripheral side of the cable carrier 11 as shown in FIG. The radiant heat from here is blocked here, and the heating of the inner power supply cable 12 and the cooling water hose 13 can be prevented. Even if an alternating current flows through the power supply cable 12, the protective cover 18 is formed of a non-magnetic material, so that the magnetic flux is shielded here and the peripheral devices can be prevented from heating.

The protective cover 18 is supported between the clamp plate 15 and the holding pin 17 in a free state. Since both ends of the protective cover 18 are connected only by the fixed end 20 and the movable end 21 of the cable carrier 11, the protective cover 18 has a curved portion. With clamp plate 15 and protective cover
18 positions can be shifted relatively.

In the present invention, a structure in which a heat insulating sheet is interposed inside the protective cover 18 may be used. In the above embodiment, the case where the protective cover 18 is formed of a non-magnetic material has been described. However, when there is no proximity heating, an iron plate may be used.

[0015]

As described above, according to the cable carrier of the induction heating apparatus according to the present invention, a protective cover is provided on the outer peripheral side of the cable carrier, and the power supply cable and the cooling water hose supported inside the cable carrier are heated. By protecting the material from radiant heat, the rubber coating can be prevented from being heated and durability can be improved.
