In order to solve the above-mentioned technical problems, the technical solution of the present invention is to provide a kind of electric cable overhead device, including a base, a support frame is fixedly installed on the base, a rotating wheel is installed on the support frame, and the rotating wheel The outer ring of the worm gear is provided with a worm gear ring, the worm gear ring is a fan-shaped structure, the base is rotatably mounted with a worm suitable for the worm gear ring gear, and the rotating wheel is provided with a clip for clamping the pull wire. A wire mechanism, the wire clamping mechanism is close to the end of the worm gear ring gear.

In the electric cable overhead device of the present utility model, as a preferred technical solution, the clamping mechanism includes a base and a cover hinged together through a hinge, and the base is fixedly installed on the On the rotating wheel, a locking mechanism is provided between the cover and the seat.

In the electric cable overhead device of the present invention, as a preferred technical solution, a first rubber pad is provided on the base body, and a second rubber pad is provided on the cover body.

In the electric cable overhead device of the present utility model, as a preferred technical solution, rollers are installed on the bottom of the base.

After adopting above-mentioned technical scheme, the beneficial effect of the utility model is:

(1) Since the rotating wheel is installed on the supporting frame, the rotating wheel is provided with a clamping mechanism for clamping the pull wire. When in use, the pull wire is placed in the clamping mechanism, and the rotating wheel is turned to raise the pull wire overhead. It is convenient for construction and reduces the labor intensity of the operator.

(2) Due to the matching worm gear ring gear and worm, during the operation, the pull wire can be raised to a suitable position, and the self-locking effect of the worm gear can be used directly to make the pull wire stay at this position. The structure is simple and easy to operate , and reduce the labor intensity of the operator.

(3) Since the seat body is provided with a first rubber pad and the cover body is provided with a second rubber pad, during use, the first rubber pad and the second rubber pad clamp the stay wire to avoid damage to the surface of the stay wire.

(4) Since the bottom of the base is equipped with rollers, it can move with the change of the overhead position of the cable during outdoor construction, further reducing the labor intensity of the operator.
