Lead shockproof hammer antiskid device

Abstract

The invention relates to a lead shockproof hammer antiskid device comprising a shockproof hammer, a wire locking mechanism and an antiskid mechanism. A steel strand is arranged on the right side of the shockproof hammer; a first erecting sleeve is arranged on the right side of the steel strand; the wire locking mechanism is arranged above the first erecting sleeve; a locking bolt is arranged in the middle of the lower end of the wire locking mechanism; clamping sleeves are arranged in the middle above the left and right sides of the wire locking mechanism; a second erecting sleeve is arrangedon the right side of the first erecting sleeve; a connecting plate is arranged above the second erecting sleeve; a pawl is arranged above the middle part of the connecting plate; a ratchet wheel is arranged above the pawl; the antiskid mechanism is arranged at the other end, corresponding to the rotating shaft of the ratchet wheel, of the connecting plate and comprises an upper antiskid plate anda lower antiskid plate, semicircular wire containing grooves are arranged in the inner sides of the middle of the upper antiskid plate and the lower antiskid plate, an antiskid head is arranged at theother end of the rotating shaft on the ratchet wheel, and an antiskid protruding strip is arranged in the middle of the antiskid head. The lead shockproof hammer antiskid device has the advantages ofbeing simple in structure, convenient to install and use and high in practicability.

Description

technical field [0001] The invention belongs to the technical field of anti-vibration hammers for wires, and in particular relates to an anti-slip device for anti-vibration hammers for wires. Background technique [0002] On high-voltage overhead lines, a small hammer is often hung on the wires near both sides of the insulator. This small hammer is called an anti-vibration hammer, which is designed to reduce the vibration of the wires due to wind; If the distance is large, when the wire is subjected to wind force, it will vibrate. When the wire vibrates, the working conditions at the wire suspension are the most unfavorable. Due to multiple vibrations, the wire will be fatigued due to periodic bending. When the overhead line span When it is greater than 120 meters, the anti-vibration hammer is generally used for shockproof; the anti-vibration hammer is composed of a heavy hammer with a certain quality, high elasticity, high-strength zinc steel strands and wire clips. The mo...

[0002] On high-voltage overhead lines, a small hammer is often hung on the wires near both sides of the insulator. This small hammer is called an anti-vibration hammer, which is designed to reduce the vibration of the wires due to wind; If the distance is large, when the wire is subjected to wind force, it will vibrate. When the wire vibrates, the working conditions at the wire suspension are the most unfavorable. Due to multiple vibrations, the wire will be fatigued due to periodic bending. When the overhead line span When it is greater than 120 meters, the anti-vibration hammer is generally used for shockproof; the anti-vibration hammer is composed of a heavy hammer with a certain quality, high elasticity, high-strength zinc steel strands and wire clips. The movement of the vibration phase is opposite, so that the vibration of the wire is eliminated or weakened. With the long-term operation and the severe test under complex and harsh weather conditions, the loosening of the bolt may cause the wire to have insufficient grip, resulting in slippage with the wire, thus losing Anti-shock protection for wires; therefore, it is very necessary to provide a wire anti-vibration hammer anti-slip device that is simple in structure, easy to install and use, strong in practicability, and effectively prevents wire accessories such as anti-vibration hammers from slipping
