Description

Overhead Ground Wire Riser

technical field

The utility model relates to an electrical tool, in particular to an overhead ground wire lifter.

Background technique

At present, in the process of replacing the straight overhead ground wire fittings with electricity, the operator lifts the overhead ground wire by manpower on his shoulders, and then replaces the fittings. However, the practice of shoulder carrying is poor in safety and reliability, labor-intensive, and prone to accidents. Therefore, it is a technical problem to be solved at present to design an overhead ground wire lifter for live replacement of straight overhead ground wire fittings.

Contents of the invention

The technical problem to be solved by the utility model is to provide an overhead ground wire lifter for replacing linear overhead ground wire fittings with electricity.

The technical scheme that the utility model solves its technical problem is:

The overhead ground wire lifter is composed of a screw, a nut, a sleeve and a hook. There is a "U" notch on the upper end of the nut. There are bolt holes on the two side walls of the "U" notch. The hook is made of epoxy resin The hook is connected with the lead screw through bolts, the screw nut is screwed on the lead screw, the sleeve is set on the lead screw, the sleeve is on the upper part of the screw nut, and an overhead ground wire hook is arranged on the sleeve. There is an afterburner handle, hang the hook on the overhead ground wire suspension cross arm, the overhead ground wire support hook supports the overhead ground wire, rotate the afterburner handle, the wire nut will drive the sleeve to move upward, and the overhead ground wire on the sleeve will move upward. The wire support hook drives the ground wire to move upward together, and the straight overhead ground wire fittings can be replaced with electricity.

Preferably, the hook is a slanted hook suitable for an angle iron cross-arm, and the middle part of the hook of the slanted hook is hinged with one end of the auxiliary rod through a first pin shaft, and at the other end of the auxiliary rod through a second pin shaft Hinged with straight hook hooks suitable for channel steel cross arms.

Preferably, the straight hook is a double-ended hook, and the hooks at the two ends are respectively suitable for different types of channel steel.

Compared with the prior art, the utility model solves the problems of poor reliability, potential safety hazards and high labor intensity of the previous shoulder-carrying working method; at the same time, the utility model is applicable to both channel steel and angle steel cross arms.

Detailed ways

As shown in the figure, the overhead ground wire lifter is composed of a screw 3, a screw nut 1, a sleeve 2 and a hook 6. There is a "U" notch on the upper end of the nut 1. On the two side walls of the "U" notch, There are bolts passing through holes, the hook 6 is made of epoxy resin plate, the hook 6 is connected with the lead screw 3 through the bolt 4, the screw nut 1 is screwed on the lead screw 3, the sleeve 2 is set on the lead screw 3, and the sleeve 2 is on the lead screw 3. On the upper part of the female 1, an overhead ground wire hook 10 is provided on the sleeve 2, and the wire mother 1 is provided with an afterburner handle 11, and the hook 6 is hung on the overhead ground wire hanging cross arm, and the overhead ground wire hook 10 supports Hold the overhead ground wire, turn the force handle 11, the wire nut 1 will drive the sleeve 2 to move upward, and the overhead ground wire support hook 10 on the sleeve 2 will drive the ground wire to move upward together, and the straight overhead ground wire fittings can be replaced with electricity .

The hook 6 is an oblique hook suitable for the cross-arm of the angle iron. The middle part of the hook handle of the oblique hook is hinged with one end of the auxiliary rod 7 through the first pin shaft 5, and is hinged at the other end of the auxiliary rod 7 through the second pin. Axle 9 is hinged with the straight hook hook 8 that is suitable for channel steel cross-arm.

Described straight hook hook 8 is a double-ended hook, and the hooks at two ends are respectively suitable for channel steels of different types.
