Abstract
The invention relates to a preformed damping vibration-proof damper, more particularly to improvement on a wire clamp structure of a preformed vibration-proof damper. According to the invention, anti-loosening and anti-sliding capabilities of the vibration-proof damper can be effectively enhanced; and it can be ensured that an installation position of the vibration-proof damper is accurate and the cable is protected from being damaged. The vibration-proof damper comprises a wire clamp; an upper portion of the wire clamp is in a hook shape; a hook surface of the hook shape is a lead clamping face and a damping non-slip mat is arranged on the lead clamping face. According to the invention, a sliding frictional force between the vibration-proof damper and the cable is strengthened and an anti-sliding capability of the vibration-proof damper is improved; besides, accuracy of the installation position of the vibration-proof damper is ensured and the cable can be protected from being damaged. In order to ensure reliability of connection between the damping non-slip mat and the wire clamp, a projection and an installation hole are arranged; and the projection is embedded into the installation hole by utilizing an elasticity of the damping non-slip mat material itself. Besides, sliding and motion of the damping non-slip mat relatively to the vibration-proof damper can be prevented. A radian of the upper portion of the clamping face is reduced and is less than an radian of the lead in order to enhance the connection reliability between the clamping face and the lead, and thus the lead is stuck in a small radian.
Description
Technical field
The present invention relates to a kind of electric power transmission equipment stockbridge damper, especially relate to the reach the standard grade improvement of clamping structure of a kind of preformed stockbridge damper.
Background technology
Aeolian vibration is the main vibration mode of aerial cable, also is to the maximum vibration of cable harm.For reducing and avoiding the infringement of aeolian vibration to cable, on cable, hang stockbridge damper now usually, effectively reduce Oscillation Amplitude and the frequency of cable under pneumatic situation, thereby reduce the fatigue damage and the fracture of cable, prolong the useful life of cable.
Stockbridge damper is to be suspended on the cable by the stockbridge damper wire clamp, and existing stockbridge damper wire clamp in use exists clamping to become flexible phenomenon, causes the stockbridge damper slippage, the inaccurate and damage cable situation in stockbridge damper location occurs.
Summary of the invention
The purpose of this invention is to provide a kind of preformed damping stockbridge damper, utilize the wire clamp of this stockbridge damper, can effectively strengthen the anti-loosening and antiskid of stockbridge damper and move ability, guarantee the stockbridge damper installation site accurately and the protection cable injury-free.
For solving the problems of the technologies described above, the preformed stockbridge damper wire clamp of the present invention comprises wire clamp, and described wire clamp top is hook-type, and the hook face of hook-type is the lead clamping face, is provided with the damping slipmat on described lead clamping face.
Described lead clamping face is provided with an installing hole; Described damping slipmat middle part is provided with a projection that matches with installing hole, and described projection embeds described installing hole, and described damping slipmat is connected on the described lead clamping face.
The radian of described lead clamping face top arc is less than the radian of described lead clamping face.
Be provided with the damping slipmat at preformed stockbridge damper wire clamp lead clamping face, increased the force of sliding friction between stockbridge damper and the cable, the antiskid that has improved stockbridge damper moves ability, has guaranteed that the stockbridge damper installation site is accurate, and can protect cable injury-free.Reliability for guaranteeing to be connected between damping slipmat and the wire clamp is provided with projection, is provided with installing hole at the clamping face correspondence position at the slipmat back side, utilize the elasticity of damping slipmat material self, and projection is embedded in the installing hole; Can prevent the relative stockbridge damper slippage of damping pad play.Be the connection reliability between increase and the lead, the present invention also reduces the radian on clamping face top, and the radian (radian of clamping face integral body) less than lead is equivalent to lead is stuck in the little radian like this.
Description of drawings
The present invention is further detailed explanation below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of wire clamp among the present invention.
1 is the lead clamping face among the figure, and 2 are the damping slipmat, and 3 is installing hole, and 4 is projection, the 5th, and the top arc.
Embodiment
The preformed stockbridge damper wire clamp of the present invention comprises wire clamp, and described wire clamp top is hook-type, and the hook face of hook-type is a lead clamping face 1, is provided with damping slipmat 2 on described lead clamping face 1.
Described lead clamping face 1 is provided with an installing hole 3; Described damping slipmat 2 middle parts are provided with a projection 4 that matches with installing hole 3, and described projection 4 embeds described installing hole 3, and described damping slipmat 2 is connected on the described lead clamping face 1.
The radian of described lead clamping face 1 top arc 5 is less than the radian of described lead clamping face 1.
When stockbridge damper was installed, the projection 4 of damping slipmat 2 was installed in the installing hole 3 of lead clamping face, and damping slipmat 2 parcels in the stockbridge damper wire clamp lead clamping face 1 are also exerted pressure by wire clamp and to be clamped lead.
