Telescopic frog for movable center turnout
The invention relates to a telescopic frog for a movable center turnout. The frog comprises a straight station track and a lateral station track which are arranged in a matched mode, a first wing track and a second wing track are arranged in a mode of being matched with the straight station track and the lateral station track, and a compensation swing unit is arranged in a mode of being matched with the first wing track and the second wing track. The side, facing the first wing rail, of the compensation swing unit sequentially comprises a rail transfer section, an elastic bendable section anda fixed section, a telescopic section is arranged on the rear portion of the side, facing the second wing rail, of the compensation swing unit, and the telescopic section is matched with the fixed section; and the compensation swing unit is connected to the controller. The influence of harmful space on rail running is reduced, the harmful space can be eliminated, the external force required for pulling the swing part is effectively reduced, the stability of the pulled short point rail is guaranteed, and then the running stability is guaranteed. The frog is compact and simple in structure, canbe exchanged with an existing fixed frog, eliminates harmful space of the frog for the urban rail transit main track subway turnout, eliminates track gauge line discontinuity, improves the comfort ofthe frog, reduces noise and is environmentally friendly.
本发明涉及伸缩型可动心道岔用辙叉，包括配合设置的直向股道和侧向股道，配合直向股道和侧向股道设有第一翼轨和第二翼轨，配合第一翼轨和第二翼轨设有补偿摆动单元；补偿摆动单元朝向第一翼轨的一侧顺次包括变轨段、弹性可弯段和固定段，朝向第二翼轨的一侧后部设有伸缩段，伸缩段与固定段配合设置；补偿摆动单元连接至控制器。本发明降低有害空间对轨道行驶的影响，能够消除有害空间，有效降低摆动部件扳动需要的外力，保证扳动后短心轨的稳定性，进而保证行车的稳定。本发明结构紧凑，简单，能够与既有固定型辙叉互换，消除城市轨道交通正线地铁道岔用辙叉的有害空间，消除轨距线不连续，提高辙叉的舒适性，降低噪音，环境友好。
