To provide an overhead wire suspension device having a damper function capable of preventing contact between a coil spring and a rod or a cylinder.SOLUTION: A suspension device 1 includes: a casing 2 whose upper end side is connected to an overhead power line M1; a rod 3 that is inserted up and down freely in the casing, has a friction member 4 at the upper end, and a lower end that penetrates an opening 8a is connected to the overhead power line M2; a compression coil spring 5a in which an upper end is locked to the friction member 4 via a spring guide 9 and a lower end is locked to a spring guide 10 within the casing 2; and a compression coil spring 5b whose upper end is locked to the spring guide 10 and whose lower end is locked to a lid 8 via a spring guide 11, within the casing 2. The springs 5a, 5b are held by the spring guides 9, 10, 11 so as not to come into contact with the casing 2 or the rod 3, and as a result, a life of a product can be prevented from being shortened and stable vibration damping performance can be obtained.SELECTED DRAWING: Figure 2
【課題】コイルばねとロッドあるいはシリンダとの接触を防止できるダンパ機能を備えた架線の吊架装置を提供する。【解決手段】吊架装置1は、上端側が架線M1に連結されるケーシング2、これに昇降自在に挿入され上端に摩擦部材4を備え開口8aを貫通した下端が架線M2に連結されるロッド3、ケーシング2内で上端がばねガイド9を介して摩擦部材4に係止され、下端がばねガイド10に係止される圧縮コイルばね5a、ケーシング2内で、上端がばねガイド10に係止され下端がばねガイド11を介してふた8に係止される圧縮コイルばね5bを具備する。ばね5a,5bは、ばねガイド9,10,11により、ケーシング2又はロッド3に接触しないように保持される結果、製品の短命化を防止でき、安定した制振性能が得られる。【選択図】図2
