PROBLEM TO BE SOLVED: To provide a trolley wire suspending device that has a relatively simple structure, eliminates the need for frequent maintenance inspection and component replacement, stably exhibits damper function, facilitates manufacture, and can be obtained at low cost.SOLUTION: An end lid 5c of the other end of a casing 5 with one end connected to a messenger wire M is hermetically inserted in a rod section 7 in a freely coming in/out manner, and the outward end is connected to a trolley wire T. A piston 6 for connecting the rod section 7 is slidably inserted into an axial direction in the casing 5. Cylindrical bellows 8 are disposed in the inside of the casing 5, the one end is hermetically closed by the piston 6, and the other end is hermetically closed by the end lid 5c of the casing 5. Orifices 9a, 9b for bringing the inside and outside of the cylindrical bellows 8 into communication are provided in the piston 6 and the end lid 5c of the casing 5. The vibration of the trolley wire T is damped by the internal pressure of the cylindrical bellows 8 with the movement of the piston 6. The internal pressure of the cylindrical bellows 8 is adjusted by the gas coming in/out through the orifices 9a, 9b.
【課題】比較的簡易な構造で、頻繁な保守点検、部材交換なく安定してダンパ機能を発揮し、製造が容易で安価に得られるトロリ線吊架装置を提供する。【解決手段】一端が吊架線Mに連結されるケーシング5の他端の端蓋5cを気密に出入り自在にロッド部7を挿入して、その外方端がトロリ線Tに連結させる。ロッド部7を結合させるピストン6をケーシング5内に軸線方向に摺動自在に挿入する。ケーシング5の内部には筒状ベローズ8を配置し、その一端部をピストン6により気密に閉鎖し、他端部をケーシング5の端蓋5cにより気密に閉鎖する。ピストン6及びケーシング5の端蓋5cに、筒状ベローズ8の内外を連通させるオリフィス9a,9bを設ける。ピストン6の移動に伴う筒状ベローズ8の内圧によりトロリ線Tの振動を減衰させる。筒状ベローズ8の内圧は、オリフィス9a,9bを通じた気体の出入りにより調整する。【選択図】図2
