４）。A wire extension car is used to feed out electric wires from a drum during overhead construction work, etc.The electric wire sent out from the drum mount is routed or suspended around a capstan that can be freely braked, and the backing caused by braking on the drum mount is avoided. Together with the tensilan, it provides sufficient braking force (reaction force) against the traction force by the winch installed on the traction side (engine station), and feeds out the wire while maintaining the required wire tension. As a type of braking device for this capstan, an electromagnetic braking device that utilizes the action of so-called electromagnetic force is conventionally known. An electromagnetic braking device rotates a disk-shaped rotor of an electromagnetic retarder, which is a type of eddy current generator, using the rotational force of a capstan generated by feeding out electric wires, and combines the eddy current generated in the rotor with the rotation of the stator. This is a device that obtains braking torque using electromagnetic force. This type of electromagnetic braking device can continuously adjust the braking torque by increasing/decreasing the excitation current to the coil wound around the stator, and since it is constituted by an electric device, it can be Although it has the excellent feature of easily allowing one-man control of several track rolling cars at once when adopted for general purpose use, due to its nature, when there is no relative speed between the rotor and stator, When the Capstor/ stops for some reason, the generated braking torque becomes zero, and even if it does not stop, when the speed becomes low, there is an inconvenience that the predetermined braking torque cannot be obtained. For this reason, in conventional electromagnetic braking devices, a band brake or the like is required for stopping and for auxiliary braking at low speeds in order to maintain a predetermined wire tension even in such cases. In order to resolve this situation, the applicant first interposed a differential gear device between the capstan and the rotor of the electromagnetic retarder, and by constantly rotating the outer box of the device, the We have developed a technology that ensures the necessary braking force by always maintaining the rotation of the electromagnetic retarder rotor above a specified level even when stopped (Japanese Patent Laid-Open No. 56-5239).

ては、延線のふらつきなどの要因となる虞れがあった。However, although conventional electromagnetic braking devices for track rolling stock that include such a differential device have the advantage that the conventional electromagnetic retarder itself can be used as is, the differential gear device As the number increases by one, it is difficult to avoid an increase in weight and cost.Also, since the rotor of the electromagnetic retarder is driven by two drive sources, the carburetor tongue and the electric motor, there is a difference in the mechanical convergence point of the respective driving forces. Because it is equipped with a dynamic gear system, if there is an extremely rapid change in speed, etc., the movable parts of the differential gear system will interfere with each other and cause unexpected relative movement, causing the speed change or other changes to occur in IJ. This may not be transmitted properly, and in locations with poor track conditions, there is a risk that this may cause fluctuations in the track.

向〔矢示Ａ方向〕と逆方向に回転させる。FIG. 1 shows an embodiment of the invention. First, to explain the configuration, this electromagnetic braking device 1 mainly includes a first rotor 2, a second rotor 3, and an electric motor 4 that drives the second rotor 3. The first rotor 2 consists of two discs τ and 2' connected by a shaft 5, and is mounted on bearings 8 and 8 so as to be rotatable in the direction of arrow A in conjunction with the capstan 7 of the rolling stock 6. Supported. Note that 9 is a suitable speed increaser, and 10 is a one-sided clutch. This one-way clutch 10 prevents the first rotor 2 from rotating in the direction of arrow B, and as a result prevents the capstan 7 of the track rolling car 6 from rotating in the direction opposite to the track running. It is something to do. The second rotor 3 is disposed between and facing the first rotors 2, and is supported by bearings 11, 11 and is rotatable around the shaft 5. A coil 12 is wound around the second rotor 3, and brushes 13, 14 and 13', 14' are connected to conductive bands 15 and 1 disposed on the shift 5, respectively, so that current can flow to the coil 12.
5'. When the first rotor 2 rotates, relative rotational resistance is generated between the two rotors 2 and 3 due to the eddy current generated due to the rotational speed difference with the second rotor 3 and the electromagnetic force of the second rotor 3. It is something. The second rotor 3 is constantly rotated by the electric motor 4 in the direction of arrow B, that is, the direction opposite to the direction in which the first rotor 2 rotates in conjunction with the capstan 7 [direction of arrow A].

る。This is because even if the capstan 7 of the track rolling car 6 stops for some reason and therefore the first rotor 2 stops, the first rotor 2 still stops.
This is to ensure that relative rotation occurs between each second rotor 2.3. Note that the electric motor 4 is used here as a means for constantly rotating the second rotor 3 in the direction B;
There is no particular question regarding the type of drive means itself.

用が為される。With such a configuration, the rotation of the electromagnetic braking device rotor 3 is added to the relative rotation, that is, the first rotor 2 and the second rotor 3.
The eddy current generated due to the rotational speed difference between the rotors 3 and the second
Due to the electromagnetic force of the rotor 3, a relative rotation is generated between the two 2 and 3, and regardless of the rotation of the capstan T, an increase or decrease in the current to the coil 12 causes the first . The force between the second rotors 2 and 3 that tries to prevent relative rotation [
Relative rotational resistance] is generated, and this is transmitted to the capstan 7 to suppress and brake the rotation of the capstan 7.

力調整が期待できる。As explained above, although it is an electromagnetic braking device,
For example, when used in a track rolling car, it maintains the effect of being able to maintain sufficient wire tension even when running at low speed or when the track is stopped, but there is no need to provide an accessory device such as a differential gear device. This reduces the weight and cost of the entire braking device. Also, since the capstan is used as a drive source to rotate only the first rotor, and the electric motor is used as a drive source to rotate only the second rotor, each force is reduced. The transmission systems are separated, eliminating mutual interference and allowing for accurate tension adjustment with fewer non-control elements.
