The invention provides a wheel set walking structure capable of adjusting the wheel distance, relates to the technical field of track maintenance equipment, and solves the problems that when passing through a harmful space at a fixed frog, an existing guide wheel collides with the frog tip or deviates from the set direction of a track, derailment is caused, and the existing guide wheel cannot pass through a turnout at a high speed. The device comprises a wheel spacing telescopic supporting device, guide wheels and guide wheel guard plate pull rod mechanisms, the wheel spacing telescopic supporting device is arranged in the middle of a vehicle body, the guide wheels and the guide wheel guard plate pull rod mechanisms are symmetrically arranged at the two ends of the vehicle body in pairs, and the guide wheels are rotationally connected with the vehicle body. One end of the guide wheel guard plate pull rod mechanism is connected with the wheel spacing telescopic supporting device, and the other end of the guide wheel guard plate pull rod mechanism is connected with the vehicle body; the transverse spacing of the guide wheels is controlled within a working interval by the wheel spacing telescopic supporting device, and the guide wheel guard plate pull rod mechanism plays a role in limiting, so that the transverse ultimate extension position of the guide wheels is limited, and the guide wheels are prevented from derailing or colliding with the tip of a frog point rail.
本发明提供了一种可调整车轮间距的轮对走行结构,涉及轨道维护设备技术领域,解决了现有的导向轮通过固定型辙叉处的有害空间时会冲撞辙叉尖端或偏离轨道既定方向导致脱轨、无法高速通过道岔的问题。该装置包括轮间距伸缩支撑装置、导向轮和导向轮护板拉杆机构,轮间距伸缩支撑装置设置在车体的中间,导向轮和导向轮护板拉杆机构成对的对称设置在车体的两端,导向轮与车体转动连接,导向轮护板拉杆机构的一端与轮间距伸缩支撑装置相连接,导向轮护板拉杆机构的另一端与车体相连接;轮间距伸缩支撑装置将导向轮的横向间距控制在工作区间内,导向轮护板拉杆机构起到限位作用,从而限制导向轮的横向极限伸长位置,避免脱轨或撞击至辙叉心轨的尖端。
