The invention discloses a highway-railway dual-purpose tractor. The highway-railway dual-purpose tractor comprises a tractor body, guiding devices are symmetrically arranged on the front side and therear side of the tractor body, and traction hooks are arranged on the front sides of the guiding devices. The guiding device comprises a guiding wheel, a fixing frame, a hydraulic telescopic column, alifting plate and a lifting groove; the guiding wheels are installed on the two sides of the fixing frame, and the upper side of the fixing frame is connected with the two sides of the tractor body through hydraulic telescopic columns. Power is provided for lifting of the fixing frame, and a lifting plate is fixedly welded to the rear side of the fixing frame; the lifting plate extends into the tractor body through a lifting groove; and the tail end of the lifting plate sleeves a fixed transverse shaft in the tractor body. Rail guiding of different heights can be achieved by adjusting the height, guiding wheels do not need to be replaced so that the tractor can adapt to groove-shaped rails and comb-shaped turnouts of modern tramcars, the passing capacity of the rails is enhanced, and safeand efficient shunting work of the tramcars is guaranteed.
本发明公开了一种公铁两用牵引车,包括牵引车本体;所述牵引车本体的前后两侧对称设有导向装置,所述导向装置的前侧设有牵引钩;所述导向装置包括导向轮、固定架、液压伸缩柱、升降板以及升降槽;所述导向轮安装在固定架的两侧,固定架的上侧设有通过液压伸缩柱与牵引车本体的两侧相连;用于为固定架的升降提供动力,所述固定架的后侧固定焊接有升降板;所述升降板通过升降槽延伸至牵引车本体的内部,且升降板的末端套装在牵引车本体内部固定横轴,本发明通过调节高度可以实现不同高度的轨道导向,无需更换导向轮,以适应现代有轨电车的槽型轨及梳子型道岔,加强上述铁轨的通过能力,保障有轨电车的调车工作安全高效。
