Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cable supply device for supplying cables, ie, cables, hydraulic, pneumatic, and other hoses to reciprocating equipment.

In general, when connecting large current cables for power, microcurrent cables for instrumentation, or hydraulic, pneumatic, or other hoses to equipment that rotates back and forth, it is important to It is necessary to enable the cables to follow the rotation smoothly. For example, in a ladle rotating device for continuous casting equipment, all of the cables for high current power for lifting and lowering, instrumentation equipment, small current cables for computers, supply hoses for air pressure and inert gas, etc. are supplied in a rotatable manner. Must. Conventionally, the method of supplying cables and hoses to this type of reciprocating equipment has been to supply cables and hoses to a cable carrier with a caterpillar movable part, with one end attached to the pivot of the reciprocating equipment and the other end attached to a fixed part. Conventionally, a hose was attached to follow the rotation of the pivot shaft, or a cable was connected with a slip ring, and a hose was connected with a rotary joint, but the above-mentioned cable carrier was not used. It requires a large amount of space, and using slip springs is extremely complicated when there are a large number of them.
With joints, it is not easy to reliably prevent leakage. Furthermore, in the case of a slip ring or a rotary joint, separate supply devices must be provided for the cable and the hose, respectively, resulting in an increase in size.

This invention was proposed in order to eliminate the above-mentioned conventional drawbacks, and aims to provide a compact cable supply device that can supply cables and hoses with a single device with a simple configuration. It is.

An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a machine frame, and within this machine frame 1, a cylindrical body 2 having a flange portion 2a at the upper end is vertically provided and rotatable by bearings 3 and 4.
This cylindrical body 2 is provided so that its center line coincides with the center of rotation of equipment that reciprocates, such as a ladle rotating device in continuous casting equipment.

The machine frame 1 consists of an upper machine frame 1a and a lower machine frame 1b, and a plurality of umbrella-shaped plates 5 each having a truncated conical upper surface through which a cylindrical body 2 is inserted are fixed to the upper machine frame 1a. A small current cable 6 or a lead-in portion 8 for a hose 7 is provided on the outer surface of the upper machine frame 1a.
A clamp portion 9 for clamping a minute current cable 6 or a hose 7 is attached to the circular portion of the cylindrical body 2. The minute current cable 6 or hose 7 led from the outside is led into the upper machine frame 1a through the lead-in part 8, and is wound spirally on the umbrella-shaped plate 5 as shown in FIG. It is guided into the cylindrical body 2, clamped by the clamp part 9, and supplied from above inside the cylindrical body 2 through the outlet 11 of the cover 10 to the reciprocating equipment.

Further, in the lower machine frame 1b, a plurality of slip rings 12 are attached to the outer periphery of the cylindrical body 2, and a brush 13 that slides on the slip rings 12 is attached to a brush holder fixed to the lower machine frame 1b. It is attached to the container 14. Further, a terminal box 15 is provided on the side of the lower machine frame 1b, and a large current cable 17 is connected from the outside to each terminal 16 in this terminal box 15. The cover 1 is connected to the brush 13 through the cylindrical body 2 and is guided into the cylindrical body 2 through a sliding connection between the slip ring 12 and the brush 13.
It is supplied through the outlet 11 of 0 to the reciprocating equipment. 18 is an insulator.

Next, the effect will be explained.

When the reciprocating equipment rotates, the cylindrical body 2 and the cover 10 rotate together following the rotation. Now, if it is rotated in the direction of arrow A in FIG. 2, the minute current cable 6 or hose 7 will be wound around the outer periphery of the cylindrical body 2 from the inner part of the spiral. Next, when it rotates in the direction opposite to arrow A, the cables 6 and 7 wound around the outer periphery of the cylindrical body 2 are unwound, and the unwound cables 6 and 7 are also wound around the umbrella-shaped plate 5. For public distribution, they are placed on the umbrella-shaped plate 5 so as to form a spiral due to their own weight. In this way, the minute current cable 6 and the hose 7 can follow the rotation of the reciprocating equipment.

Further, regarding the large current cable 17, the slip ring 12 allows rotation of the cylindrical body 2, that is, rotation of the reciprocating equipment.

In the cable supply device of the present invention, a cylindrical body is provided vertically and rotatably within the machine frame, and minute current cables, hoses, etc. are connected to umbrella-shaped plates provided at the top or bottom of the cylindrical body. The large current cable is supplied by a slip ring installed at the bottom or top of the cylindrical body, so all cables can be supplied with one device with a simple configuration. , and is extremely compact. Further, there is no need for the complexity of supplying a large number of minute current cables through slip rings.

FIG. 3 shows the second invention, in which an umbrella-shaped plate 20
A grease pipe 21 is installed on the back surface of the umbrella plate 20, and a grease outlet 22 is provided on the upper surface of the upper edge of the umbrella-shaped plate 20. Further, the grease injection port 23 is provided on the outer surface of the machine frame 24. In addition, 25 is a cylindrical body, 26 is a cable or a hose, and the machine frame 24, the cylindrical body 25, and the umbrella-shaped plate 20 have the same structure as that shown in FIG. 1, but in this invention, a slip ring is used. It is not directly related to the cable supply means used.

In the cable supply device having the above configuration, when the cylindrical body 25 rotates, the cylindrical body 25 winds up the cables 26, but at this time, grease is pushed out onto the upper surface of the upper edge of the umbrella-shaped plate 20. Therefore, the cables 26 are coated with grease, and as the cables 26 slide, the sliding surface of the umbrella-shaped plate 20 is also coated with grease. Therefore, cables 2
6 and the sliding surface of the umbrella-shaped plate 20 becomes small, so that when the cables 26 are unwound, the cables 26 smoothly slide on the inclined surface of the umbrella-shaped plate 20 due to their own weight. It can form an orderly spiral. If such grease is not used to lubricate, and the umbrella plate is tilted gently, the weight of the cables will create a spiral, making it impossible to unwind normally. If grease lubrication is performed at the same time, normal unwinding can be achieved even if the umbrella plate 20 is inclined gently. For this reason, the umbrella-shaped plate 20
When it is desired to stack a large number of cables on top of each other, the umbrella plate 20 can be sloped gently to reduce its height, thereby reducing the size of the entire cable supply device.

4 and 5 show a third invention, in which presser bars 33 are radially attached to the machine frame 30 and parallel to the upper surface of the umbrella-shaped plate 31 at intervals slightly larger than the diameter of the cables 32. It was attached to. 34 is a cylindrical body.

This presser bar 33 can prevent the cables 32 from being overlapped as shown by arrow B in FIG. 6 when the cables 32 are unwound. Therefore, even if the slope of the umbrella-shaped plate 31 is made gentle, the umbrella-shaped plate 31
The cables 32 can be unwound so as to form a normal spiral upward, so that the inclination of the umbrella-shaped plate 31 can be made gentler, the height can be reduced, and the dimensions of the entire cable supply device can be reduced.
