Problems solved by technology

[0003] However, since the installation position of the anti-vibration hammer is a certain distance from the tower where the staff is located, it is necessary to lengthen the safety belt and then stretch out the body for long-distance installation. At the same time, the traditional anti-vibration hammer is connected to the wire through a bolt structure. , this installation process is extremely risky

Embodiment 1

[0031] refer to figure 1 , which is the first embodiment of the present invention, provides a self-locking electric anti-vibration hammer, the anti-vibration hammer includes a clamp unit 100, a connection unit 200 and a hammer head unit 300; wherein, the clamp unit 100 is an anti-vibration hammer The part used to clamp the power cable, that is, the head of the anti-vibration hammer, and the connection unit 200 is used to connect the hammer unit 300, and the connection assembly 202 in the connection unit 200 can be used to transmit power to limit the clamp unit 100 The clamping state; the hammer head unit 300 is the hammer head style of a traditional anti-vibration hammer, which is used to reduce the vibration existing on the power cable. Further, the hammer head unit 300 is used to provide the driving force when the wire clamp unit 100 is clamped , The difference from the traditional anti-vibration hammer is that the hammer heads at both ends are split structures.

Embodiment 2

[0036] refer to Figure 2~4 , is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that: the whole of the wire clamp hook 101 is divided into a bending part 101a, a neck 101b and a connecting part 101c from top to bottom, wherein, The curved portion 101a is in the shape of a semi-circular ring in the radial direction, and a limiting groove 101d is opened in the side wall of the inner ring, and the limiting groove 101d starts from the end of the curved portion 101a, and is finally flush with the bottom of the connecting portion 101c; the connecting portion 101c is fixed on the top of the connection housing 201 .

[0037]The cladding plate 102 is in the shape of a semicircle in the radial direction, one end of which is hinged in the groove of the neck 101b, and the other end is mated and connected in the limiting groove 101d; the outer ring side wall of the cladding plate 102 is provided with a limiting arc groove 102a ...

Embodiment 3

[0042] refer to Figure 2-5 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: a mounting groove 201a is opened in the side wall of the lower end of the connection housing 201, and limiting grooves 201b are symmetrically opened on the side walls of both ends. , and a connecting hole 201c is opened on the side wall of the middle part thereof.

[0043] The connection assembly 202 includes a driving part 202a and a connecting part 202b, both of which are mated and connected. One end of the driving part 202a is located in the installation groove 201a, the other end extends in the wire clip hook 101, and the connecting part 202b is arranged in the installation groove 201a.

[0044] The driver 202a includes an arc-shaped drive plate 202a-1 and a drive rod 202a-2 connected to the top side wall of the arc-shaped drive plate 202a-1, wherein the arc-shaped drive plate 202a-1 is located in the installation groove 201...

Abstract

The invention discloses a self-locking electric stockbridge damper, which comprises a wire clamp unit, a connecting unit and hammerhead units. The wire clamp unit comprises a wire clamp hook and a cladding plate arranged at the neck part of the wire clamp hook; the connecting unit is arranged at the bottom of the wire clamp hook and comprises a connecting shell and a connecting assembly arranged in the connecting shell; and the hammerhead units are symmetrically arranged on the two sides of the connecting unit, and each hammer head unit comprises a first connecting rod, a second connecting rod and hammer heads arranged at the ends of the two connecting rods. The wire clamp unit is of a movable clamping structure, the movable cladding plate of the wire clamp unit is driven by the connecting unit, and the driving force of the connecting unit comes from the deflection effect when the hammer heads are placed; when the hammer heads are placed from a vertical state to a horizontal state, the connecting rods of the hammer heads push the driving rod to move upwards through power generated when the hammer heads are placed, and then the cladding plate and the wire clamp hook are pushed to be clamped on the power cable to form a fixed structure; and the installation process is simple, and connection is convenient.

Description

technical field [0001] The invention relates to the technical field of electric auxiliary fittings, in particular to a self-locking electric anti-vibration hammer. Background technique [0002] The span of the high-voltage overhead line is large, and the tower is also high. When the wire is blown by a strong wind, a strong vibration will occur. When the conductor vibrates, the working conditions are the most unfavorable where the conductor hangs. Long-term and periodic vibration will cause fatigue damage to the wires, causing strands and wires to break. Sometimes strong shocks can damage hardware and insulators. In order to prevent and reduce the vibration of the wire, a certain number of anti-vibration hammers are generally installed near the suspension wire clamp. When the wire vibrates, the anti-vibration hammer also moves up and down. Generate a force that is asynchronous or even opposite to the vibration of the conductor, which can reduce the vibration amplitude of ...
