Description of drawings
Fig. 1 is the structural representation of the anti-dancing device of the utility model damping;
Wherein, 1-yoke plate, 2-upper end cover, 3-bottom end cover, 4-piston, 5-piston rod, 6-damping ring, 7-ballast spare.
Embodiment
Below in conjunction with accompanying drawing the anti-dancing device of damping of the present utility model is described in further detail.
As shown in Figure 1, the anti-dancing device of this routine damping comprises yoke plate 1, upper end cover 2, bottom end cover 3, piston 4, piston rod 5, rubber-based high damping material 6 and ballast spare 7.For easy disassembly and replacing parts, upper end cover 2 and bottom end cover 3 are designed to C type or U-shaped structure, after fastening, the two forms the rectangular enclosure of hollow; Be installed with damping ring 6 and the piston 4 that is arranged in the damping ring centre bore in the shell, piston 4 is installed in an end of piston rod 5, the other end of piston rod 5 passes outside the bottom end cover 3 and ballast spare 7 is installed, the top of upper end cover 2 also is installed with yoke plate 1, this yoke plate 1 is bolted on the conductor spacer body of bundle conductor conductor spacer, and clamps each bundle conductor by the wire clamp that is installed on the conductor spacer body periphery.If conductor spacer adopts the conductors on quad bundled conductor spacer, then the conductor spacer body can be rectangle or annular, when being rectangle, can one wire clamp respectively be installed at four jiaos of places at the conductor spacer body, when being annular, can fix four wire clamps in the periphery of conductor spacer body; If conductor spacer adopts the multiple fission conductor conductor spacer, then fix as required a plurality of wire clamps in the periphery of annular space rod body.Damping ring 6 preferably adopts rubber-base damping material to make, setting by damping ring, under dither, produce between damping ring 6 and the piston 4 and do relatively reciprocating motion, thereby consume energy by vibration attenuation, guaranteed the reliability and stability of whole conductor galloping system, good power consumption effect particularly arranged under the high frequency form, simultaneously also corresponding reduced that the viscoelastic damping anti-dance device is destroyed under dither may.In order better to bring into play the usefulness of damping ring 6, dispose ballast spare 7 in the lower end of piston rod, the quality of this ballast spare can be configured according to the actual requirements, therefore can bring following advantage: offer on the one hand the larger impulse inertia power of piston; On the other hand with the inherent characteristic of damping ring 6 tuning whole conductor galloping system vibrations.
The operation principle of this damping anti-galloping device is:
1, when transmission pressure bears less ice and wind load, this moment, the vibrational energy of damper piston and piston rod was less, it is the power consumption effect that damper is answered main manifestations, damper inner piston rod energy loss in thereby rubber-based high damping material reciprocating produces in pushing piston and the damper under the inertia force of ballast drives, during use, the inertia force that the ballast spare of damper 7 produces makes piston rod 5 pushing pistons 4 reciprocating with respect to damping ring 6, and damping anti-galloping device consumes the line oscillation energy by vibration attenuation;
2, when bearing the greater impact load, this moment, the vibrational energy of damper piston and piston rod was also larger, it is tunning effect that damping anti-galloping device is answered main manifestations, damping anti-galloping device under this state, undertaken tuning by ballast spare 7 and damping ring 6 by the damping characteristic to the conductor galloping system, thereby change the inherent feature of conductor galloping system vibration, thereby reach the effect that inhibition is waved.
When bearing less oscillatory load, this damping anti-galloping device main manifestations is the power consumption effect; When bearing the greater impact load, this damping anti-galloping device main manifestations is tuber function.
When practical application, be installed on the conductor spacer body of bundle conductor conductor spacer by the yoke plate 1 of bolt with anti-dance device first, clamp again each oidiospore wire of transmission pressure by the wire clamp that is installed in conductor spacer body periphery, when transmission line is waved, this damping anti-galloping device produces corresponding inertial impact force by additional ballast spare 7, and with the damping ring vibration-generating power consumption that arranges, wave energy by vibration attenuation consumption, thereby reach the effect that reduces to wave response, have simultaneously good stability.
The viscoelastic damping anti-dance device that this is routine need not the instruction of extraneous control centre, does not also need smart quick sensor-based system simultaneously, can consume energy and change the characteristic of damping ring in the conductor galloping process, has simultaneously good stability and robust performance.
