Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brake device for a wire carrier.

[0002]

2. Description of the Related Art A wire carrier is used to rotatably support a rotating body such as a drum or reel wound with a wire strip such as an electric wire, a branch line, or an optical fiber. It is used for construction work. A rotating body such as a drum or a reel supported by the wire carrier has, for example, disk-shaped flanges having a diameter larger than the diameter of the cylindrical member at both ends of the cylindrical member. The flange is arranged substantially concentrically with the central axis of the cylindrical member, and a through hole is provided in the central portion along the central axis of the cylindrical member, into which the shaft of the wire carrier is inserted. The shaft of the wire reel is inserted into the through hole provided at the center of rotation of the rotating body,
The rotating body is rotatably supported by the wire transfer stand. The filament wound around the rotating body is fed from the rotating body by the rotation of the rotating body rotatably supported by the wire reel.

[0003] By the way, in the work of replacing electric wires stretched on a utility pole or the like, for example, one end of an existing electric wire stretched on a utility pole is set on a wire winding vehicle and the other end is set on a wire reeling stand. Connected to the end of a new wire wound around a drum rotatably supported on. When the electric wire winding vehicle is operated while the drum is supported by the wire transfer stand to wind up the existing electric wire, the existing electric wire pulls the drum to rotate, and the new electric wire is pulled out from the drum. The new electric wire pulled out from the drum is erected on a utility pole.

[0004]

However, if the electric wire winding vehicle is stopped to suspend or end the electric wire refilling work, the electric wire winding is interrupted, but the electric wire winding vehicle pulls the electric wire. The rotating drum may not stop rotating for a while due to inertial force even if the electric wire winding vehicle stops. When the drum spins like this,
In other words, when the drum rotates while the winding of the electric wire by the electric wire winder is stopped, the excess electric wire is supplied and the electric wire hung on the electric pole hangs down, and the other electric wires, communication wires, buildings and the ground It may come into contact and damage the wire. In addition, the electric wire wound on the drum may be unwound, and the electric wire may be irregularly wound, which may cause the electric wire to have a habit.

On the other hand, when the electric wire winding vehicle is operated while the rotation of the drum is stopped and the new electric wire wound on the drum is towed, if the drum attached to the wire reel does not rotate, the electric wire winding The drum pulled by the car may be dragged along with the wire carrier, or the wire carrier may fall.

An object of the present invention is to allow the rotation of the rotating body when the filament wound around the rotating body is drawn out, and to promptly stop the rotation of the rotating body when the drawing of the filament is stopped. It is to provide a brake device for a carriage.

By sandwiching the first and second brake members and pressing the first and second brake members against the disc-shaped member, it is possible to stop the rotating body that is rotating by inertial force. At this time, at least one of the first and second brake members is supported slidably via a spring member that urges the first and second brake members toward each other. Even if the brake member is pressed by the disc-shaped member of the rotating body, the spring member is deformed, so that it is possible to prevent the contact pressure between the brake member and the disc-shaped member from becoming too large. Therefore, according to the brake device for a wire carrier of the present invention, the rotation of the rotating body is permitted when the filament wound on the rotating body is drawn out, and the rotation of the rotating body is promptly rotated when the drawing out of the filament is stopped. To stop the, adjust the feed amount of the brake member sent by the feed mechanism,

At this time, since the screw rod member is axially supported by the base body, it does not project from the base body. Therefore, the brake device of the present invention can reduce the possibility that an operator is caught on the handle or the screw rod member protruding from the base body.

Further, the fixing means of the brake device of the present invention comprises one gripping member fixed to the base body and the other gripping member connected to the one gripping member so as to be openable and closable in a hinge shape. A connecting pin that connects the other holding member to the one holding member in a hinge-like manner so as to be movable along the axial direction, and the other of the other holding members connected by the connecting pin on the opposite side of one end of the other holding member. A through hole provided at an end portion, a single rod-shaped member which is formed so as to be inserted into the through hole and is threaded, and a rod-shaped member formed at one end portion of the rod-shaped member It is configured to include a lockable locking portion and a nut screwed into a screw cut at the other end of the rod-shaped member.

In the fixing means thus constructed, the rod-shaped member is inserted into the through hole of the other holding member in a state where the nut is screwed to the other end of the rod-shaped member, and one of the inserted rod-shaped members is inserted. By locking the end portion to one of the gripping members and fastening the gripping member with a single rod-shaped member having a thread and a nut, it is possible to easily attach / detach the brake device to / from the wire carrier. it can. Further, since the other holding member is connected by the connecting pin so as to be movable in the axial direction, the clamping position of the other holding member can be changed without changing the fixed position of the brake device. For this reason, the mountable range of the brake device to the wire carrier can be expanded.

The elastic force that presses 7 against the flange 305 can be controlled. Therefore, the electric wire 311 wound around the drum 301
Allows the drum 301 to rotate when is pulled out,
The frictional force between the inner surface pad 35 and the outer surface pad 47 and the flange 305 of the drum 301 can be adjusted so that the rotation of the drum 301 is promptly stopped when the pulling out of the electric wire 311 is stopped. Therefore, according to the brake device 1 of the present embodiment, the line transfer stand 2 is operated without human intervention.
