摘要： An apparatus grips tie plates and guides new ties during replacement of worn out ties in the road bed of a railroad track. Mechanical grip elements grip tie plates and secure them against the rail, while an old tie is removed and a new tie is inserted. A spring arrangement automatically self-centers opposing pairs of grip elements. That is, when beginning to grip a tie plate, each pair of mechanical grip elements will automatically center about the tie plate prior to securely gripping the tie plate and without moving the tie plate. The grip elements are supported by an apparatus frame. A frame lifter moves the apparatus frame vertically between an upper and a lower position relative to a vehicle frame of a tie replacer vehicle. A tie guide includes rollers on the underside thereof for minimizing friction between ties being inserted and the tie guide. Sweepers are mounted to the apparatus frame to clean off a tie as it is being inserted.
摘要翻译： 一个装置在铁轨道路床上更换破旧的连接件时，夹紧连接板并引导新的纽带。 机械抓握元件夹紧连接板并将其固定在轨道上，而旧的领带被移除并且插入了新的领带。 弹簧布置自动地将相对的一对夹紧元件自对中心。 也就是说，当开始抓住连接板时，每对机械把手元件将在牢固地夹紧连接板之前自动围绕连接板中心并且不移动连接板。 手柄元件由装置框架支撑。 框架升降机使装置框架相对于系带替代车辆的车架在上部和下部位置之间垂直移动。 领带引导件包括其下侧的滚子，用于最小化插入的连接件与连接引导件之间的摩擦。 清扫器安装到设备框架上，以便在被插入时清洁系带。
