High-altitude wind pressure resistance preventing vibration damper and mounting method thereof

Abstract

The invention discloses a high-altitude wind pressure resistance preventing vibration damper and an installation method thereof, and belongs to the technical field of vibration dampers. The high-altitude wind pressure resistance preventing vibration damper comprises a steel strand formed by twisting a plurality of steel strands, the two ends of the steel strand are fixed to a hammer head, the middle of the steel strand is sleeved with a fixed protection sleeve, and a chuck used for clamping a cable is welded to the middle of the protection sleeve; and a locking hole is formed in the symmetrical face, connected with the steel strand, of the hammer head, and a locking assembly used for assembling is inserted into the locking hole. According to the high-altitude wind pressure resistance preventing vibration damper and the mounting method thereof, in the rotating process of a locking inner rod inserted into a locking hole and a locking outer rod and a reinforcing rod, the locking outer rod and the reinforcing rod slowly make contact with an inserting rod, a gear and a rotating lead screw synchronously rotate, a locking sleeve is driven to ascend or descend along a groove position, the locking sleeve descends to be separated from the annular groove for unlocking, the gravity center of the balance weight ball always faces downwards, and the balance weight ball tends to be balanced, so that the swing frequency of the hammer head is reduced, the hammer head is confronted with wind resistance, and the high-altitude windproof purpose is achieved.

Description

technical field [0001] The invention relates to the technical field of anti-vibration hammers, in particular to a high-altitude anti-vibration hammer for wind pressure resistance and an installation method thereof. Background technique [0002] The anti-vibration hammer is designed to reduce the vibration of the wire caused by the wind. The pole position of the high-voltage overhead line is relatively high, and the span is relatively large. When the wire is subjected to wind force, it will vibrate. When the conductor vibrates, the working conditions are the most unfavorable where the conductor is suspended. Due to multiple vibrations, the wire will be fatigued and damaged due to periodic bending. When the span of the overhead line is greater than 120 meters, the anti-vibration hammer is generally used for anti-vibration. In recent years, a kind of anti-vibration hammer with no bolt structure has been introduced from Europe—the pre-twisted anti-vibration hammer, which compl...

AI Technical Summary

Problems solved by technology

[0005] has the following problems. Its anti-vibration counteracts the vibration of its cable through the reciprocating swing of the hammer head, and the passing area increases. contact area, resulting in an increase in its resistance, but it swings more frequently and easily
