Problems solved by technology
However, due to the downward direction of the bolt head, the combined effect of gravity, wind force and the accumulated vibration of the line, the bolt is easy to loosen due to its rotation. Anti-shock safety factor, so that the wire runs in irregular and large-amplitude vibration for a long time, which is prone to fatigue, broken strands or even broken wires
When the anti-vibration hammer slips, it is necessary to apply for a power outage on the line, which seriously affects the safe and stable operation of the line and economic benefits, and it is time-consuming and laborious to restore the position of the anti-vibration hammer, and the labor intensity of the maintenance workers is high

Embodiment Construction
[0026] The following combined with the attachment and specific embodiments to further explain the present invention in detail.It should be understood that these embodiments are used to illustrate the basic principles, main characteristics, and advantages of the present invention, and the present invention is not limited by the scope of the following examples.
[0027] Such as Figure 1-3 It is shown, a seismic hammer for fixing on the wire 50, including a fixed seat with an open tank 111 with a open tank 111, a line clip 21 with an open tank 211, fixed seat 11 and wire clip clip21 Fixed with the screw 32 through the bolt 31.The lower part of the fixed seat 11 is fixed with perforation. The perforation is fixed with hammer wiring 12, and the ends of the hammer line 13 are fixed with hammer body 13, and the extension direction of the hammer line 12 and the wire 50 is consistent.
[0028] The bolt 31 is set vertically, and the bolts are at the bottom of the thread clip 21.The relative...

The invention discloses a shake-proof hammer used for being clamped and fixed to an electric wire and an installation method of the shake-proof hammer. The shake-proof hammer comprises a fixing base and a wire clamp, wherein the fixing base and the wire clamp are fixedly connected through a bolt and a nut, the bolt is vertically arranged, the head of the bolt is located below the wire clamp, multiple bolt head side faces are evenly distributed on the head of the bolt, protruding edges are arranged on the left side and right side of the lower portion of the wire clamp respectively, and a limiting groove is formed between the two protruding edges. The shake-proof hammer further comprises an anti-loose piece used for preventing the bolt from rotating automatically, wherein the anti-loose piece comprises a connecting section and a side wall section, the connecting section is connected to the bolt in a sleeved mode and located in the limiting groove, and the side wall section is connected to the connecting section and can right faces one bolt head side face after being bent. According to the shake-proof hammer, due to the fact that the connecting section of the anti-loose piece is additionally arranged between the bolt and the wire clamp, the side wall section of the anti-loose piece is bent downwards to be attached to the bolt head side faces after the bolt is fastened, in this way, the bolt is effectively prevented from rotating automatically and is not prone to looseness, and the shake-proof hammer is prevented from sliding on the electric wire. By the adoption of the shake-proof hammer and the installation method of the shake-proof hammer, the normal operation level of line equipment is improved and safe and stable operation of the line equipment is guaranteed.
Description
Technical field [0001] The invention specifically involves a shock -proof hammer and installation method applied to the transmission line. Background technique [0002] Installing shock -proof hammer on the transmission line is an important earthquake prevention measure.The shock -proof hammer usually includes a fixed seat with an open tank with an open tank, a thread clip with an open tank with an open tank, and the lower part of the fixed seat is fixed with perforation. There is a hammer wiring in the perforation.The fixed hammer is the body. The fixed seat is fixed with the threading of the wire clip through the bolt.The trough is relative to the offline slot.The requirements for the installation of line shock -proof hammers are high.After installation, the hexagonal nut above the screw is fixed in the nuthole of the fixed seat, which will not loosen.However, due to the overall effect of the bolt head, due to the influence of gravity and wind power, and the accumulated vibrati...
