technical field

The utility model relates to the technical field of power line construction equipment, in particular to a pre-twisted wire clamp anti-vibration hammer.

Background technique

At present, in transmission lines, anti-vibration hammers with bolt-type clamp structures are widely used. The anti-vibration hammer of the traditional bolt-type clamp structure is generally fixed on the wire by bolts. With the vibration during the operation of the line, it is easy to cause relaxation between the wire and the clamp. In order to achieve accurate torque during the installation and construction of the anti-vibration hammer of the traditional bolt-type clamp structure, a torque wrench must be equipped, which increases the difficulty of construction.

Utility model content

The pre-twisted clamp anti-vibration hammer of the utility model is suitable for LGJ-630/45 steel-cored aluminum stranded wire or wires with similar diameters. The pre-twisted wire clip anti-vibration hammer of the utility model can effectively solve the problems of difficult installation, low construction efficiency, inconvenient acceptance and unstable operation of the existing bolt type anti-vibration hammer. The hammer head adopts the tuning fork type, which can effectively solve the problem of collision between the drum type anti-vibration hammer and the steel strand, and prevent water accumulation and corrosion. At the same time, the size of the hammer head is modified to effectively solve the problem of the pre-twisted wire clamp anti-vibration hammer corona and ensure the safe and stable operation of the line.

As a further improvement of the utility model, the end of the pre-twisted wire is set in a duckbill shape. The end treatment of the pre-twisted wire can effectively solve the problem of anti-vibration hammer corona of the pre-twisted wire clamp, and ensure the safe and stable operation of the line.

As a preferred technical solution of the present utility model, a layer of galvanized layer is provided on the outer surface of the clamp body and the hammer head, the hammer head is a tuning fork type, and one end located on the outside is set as a circular arc transition surface, and the other One end is two symmetrically arranged hemispheres. The radius of curvature of the hammer head is increased and the surface is treated to prevent water accumulation and corrosion. The size of the hammer head is modified to effectively solve the problem of anti-vibration hammer corona of the pre-twisted wire clamp and ensure the safe and stable operation of the line. The shape of the hammer head is similar to The tuning fork increases the radius of curvature of both end surfaces, thereby reducing pollution to the surrounding electromagnetic environment.

The utility model utilizes the pre-twisted wire to wind the clamp body and the overhead wire. The pre-twisted wire has a strong grip on the overhead wire, and the connection is firm. , greatly extending the service life of the wire. Moreover, the pre-twisted clamp anti-vibration hammer is easy to install, and can be installed in place without tools, saving time and effort and improving efficiency.
