Wire coil paying-off device and paying-off method
Technical Field
The invention relates to a wire coil pay-off device, and belongs to the field of electric power.
Background
In the process of electrical construction, wires or cables are often required to be unwound and wound on a wire coil for convenient unwinding and winding. In the electrical construction, a wire coil is required to be installed on a special pay-off rack; the existing wire coil unfolding frame is more traditional in design and can not be used universally, and wire coils of different types are often required to be used in electrical construction. In addition, the traditional pay-off device is very heavy, low in use efficiency and inconvenient to carry and transport.

Preferably: the wire coil paying-off device further comprises a shaft pin, a deceleration braking arc plate, a tension spring and a deceleration pedal, the shaft pin is installed at the joint of the connecting angle steel and the fixed channel steel, the deceleration braking arc plate is installed at the top of the front end of the inner side of the shaft pin, the tension spring is installed at the bottom of the deceleration braking arc plate, and the deceleration pedal is installed at the rear end of the outer side of the shaft pin.
Preferably: and a plurality of screw holes are formed in the connecting positions of the connecting angle steels and the movable channel steels at equal intervals and are connected through fixing bolts.
A paying-off method of a wire coil paying-off device comprises the following steps: preparing two wire coil paying-off devices, then adjusting the size of a gap between two channel steels, clamping one end of a wire coil into the gap, and clamping the edge of the wire coil in guide rails of three wheels; the other end of the wire coil is arranged in another wire coil paying-off device according to the step one; starting the horizontal jacks of the two wire coil paying-off devices, simultaneously reducing the arc length formed by the contact points of the wheels at the two sides and the wire coil, and pushing the six wheels to support the wire coil to leave the ground; when the wire is pulled, the rotation of the six wheels realizes the rotation of the whole wire coil; when the wire pulling is stopped, the foot steps on the deceleration brake pedal to decelerate until the wire coil stops rotating.
The invention has the beneficial effects that: the invention has simple structure and reasonable design, can freely pay off and brake at any time, can install wire coils with different types, is convenient to carry and carry, and is suitable for wire coils with different sizes and heights.
