Automatic locking vibration damper

Abstract

The invention belongs to the technical field of anti-vibration hammers and particularly relates to an automatic locking anti-vibration hammer. The hammer comprises a main hammer head and a connectingrod, the two ends of the connecting rod are connected with connecting ejector blocks, and the connecting ejector blocks are connected with the main hammer head which is connected with an adjusting balancing weight; and a pressing arc plate is arranged in the connecting ejector block and connected with a pressing bolt. The middle part of the connecting rod is connected with a connecting sleeve; theconnecting sleeve is sequentially connected with a middle connecting block, a middle connecting rod and a self-locking wire clamp; the self-locking wire clamp comprises an upper clamping plate, a lower clamping plate and a locking pull rod, the lower part of the locking pull rod is provided with second ring teeth, the outer sides of the second ring teeth are provided with locking ring plates, theinner side surfaces of the locking ring plates are provided with first ring teeth, the outer side surfaces of the locking ring plates are connected with pressure springs and guide rods, and the end part of the locking pull rod is provided with a threaded head; the anti-vibration requirements of various overhead lines can be met by adjusting the balancing weight, the position and the angle of thehammer head and other measures, the rapid installation on the overhead lines can be achieved, and meanwhile, the loosening of wire clamping after long-term work can be effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of anti-vibration hammers, in particular to an automatic locking anti-vibration hammer. Background technique [0002] Tensile insulators are used to insulate and fix wires in high-voltage overhead transmission and distribution lines. They are important components in the process of erecting long-distance and long-span transmission lines. The connection of components is most affected by long-term vibration. Due to multiple vibrations, the conductor will be fatigued due to periodic bending. When the span of the overhead line is large, it can be achieved by setting anti-vibration hammers on the conductor at intervals. For the purpose of anti-vibration, it can produce a movement opposite to the vibration phase of the wire, thereby reducing or eliminating the vibration of the wire caused by the wind; the traditional wire anti-vibration hammer is fastened to the wire by the cooperation of bolts and nuts, and the po...

[0002] Tensile insulators are used to insulate and fix wires in high-voltage overhead transmission and distribution lines. They are important components in the process of erecting long-distance and long-span transmission lines. The connection of components is most affected by long-term vibration. Due to multiple vibrations, the conductor will be fatigued due to periodic bending. When the span of the overhead line is large, it can be achieved by setting anti-vibration hammers on the conductor at intervals. For the purpose of anti-vibration, it can produce a movement opposite to the vibration phase of the wire, thereby reducing or eliminating the vibration of the wire caused by the wind; the traditional wire anti-vibration hammer is fastened to the wire by the cooperation of bolts and nuts, and the power line construction personnel in the high altitude When installing the wire anti-vibration hammer, the staff need to use auxiliary tools or people to climb directly on the wire to work. The disadvantage is that the staff is only in a state of high concentration of physical strength and spirit, and cannot completely tighten the bolts and nuts. At the same time, in the process It will consume a lot of physical strength of the staff, resulting in low work efficiency. After working for a long time, the wire anti-vibration hammer is easy to slide on the wire due to the loosening of the thread, thereby reducing the anti-vibration effect or even having a negative effect. It is necessary to install an automatic locking anti-vibration hammer
