Description
Technical Field
The invention relates to the field of protection hardware fittings, in particular to a cable protection hardware fitting for power engineering.
Background
The electric power fitting can be classified into a protection fitting, a strain clamp, a suspension clamp, a connecting fitting, a splicing fitting, an equipment clamp, a T-shaped clamp, a stay wire fitting, a bus fitting and the like according to the action and the structure classification, wherein the protection fitting is provided with a damper, and the damper is arranged for reducing vibration of a wire caused by wind power pulling. The high-voltage overhead line pole is higher, and the span is great, when the wire receives the wind force effect, can take place the vibration. The operating conditions at the wire suspension are most disadvantageous when the wire vibrates. Due to the multiple vibrations, fatigue failure of the wire occurs due to periodic bending. When the span of the overhead line is greater than 120 meters, a damper is generally used for vibration prevention.
When the shockproof hammer is installed, the shockproof hammer needs to climb to an installation position, and then is installed by using a spanner. The constitution of the staff is a great test, and a great deal of physical strength of the staff is consumed in the process, so that the staff is not safe and not fast.
The chinese patent with the publication number CN104184096B discloses an automatic locking damper, which is pushed to a set position by an insulating reverse brake operating lever, and then the pull ring is hooked and pulled back by a hanging mechanism on the head of the insulating rod, so that the automatic locking damper is prevented from sliding back in the pulling process due to the action of the reverse hanging teeth.
The Chinese patent with the publication number of CN110676787B discloses a cable damper, which is provided with two semi-arc bearing plates and a semi-arc pressing cover plate which are mutually hinged, a traction rod at the bottom of the semi-arc pressing cover plate is wound on the inner side of a traction rod clamping plate on a connecting plate, so that the function of traction limit can be formed, and the semi-arc bearing plates are prevented from warping upwards and loosening.
According to the first method, through the action of the inverted hanging teeth, the anti-vibration hammer is prevented from being automatically locked to slide back in the pulling process, and the second method can form the action of pulling limitation through the fact that the pulling rod at the bottom of the half-arc pressing cover plate is wound on the inner side of the pulling rod clamping plate on the connecting plate, when the cable shakes, the anti-vibration hammer is easily caused to displace on the surface of the cable, the cable is reserved for preventing thermal expansion and contraction, the middle part of the cable is lower due to the gravity, the anti-vibration hammer moves to the middle part of the cable, so that the anti-vibration effect cannot be achieved on the cable, and even the middle part of the cable is possibly caused to be broken due to overlarge pressure.
