The invention relates to the technical field of railway traction devices, in particular to a highway and railway dual-purpose tractor anti-derailment device which comprises a guide frame, guide wheels, a controller, a detection mechanism and an adjusting mechanism. The detection mechanism is used for detecting the height and side distance change of the track when the road-railway dual-purpose tractor runs on the track; the detection mechanism and the adjusting mechanism are arranged in the highway and railway dual-purpose tractor, when the highway and railway dual-purpose tractor drags a train, the detection mechanism detects the height change of the rails and the change of the distance between the guide rails and feeds back the changes to the controller, and the controller controls the adjusting mechanism to adjust the relative position between the guide wheels and the guide rails. The guide wheels are attached to the guide rail all the time, contact is more sufficient, and the situations that after the road-railway dual-purpose vehicle travels on the rail for a period of time, contact between the guide wheels and the rail is insufficient or the guide wheels deviate, and rail climbing and derailing occur when the road-railway dual-purpose vehicle brakes and passes through a curve and a fork area are reduced.

    本发明涉及铁路牵引装置技术领域,尤其涉及一种公路铁路两用牵引车防脱轨装置,包括导向架、导向轮、控制器、检测机构和调整机构;所述检测机构用于检测公路铁路两用牵引车在轨道上行驶时轨道的高低和侧距变化;通过在公路铁路两用牵引车内设置检测机构和调整机构,在公路铁路两用牵引车牵引列车时,检测机构检测轨道的高低变化以及导轨之间间距的变化,再反馈至控制器,控制器控制调整机构调整导向轮与导轨之间的相对位置,使得导向轮始终贴合导轨,接触更充分,减少出现公路铁路两用车在轨道上行驶一段时间后出现导向轮与轨道接触不充分或者导向轮走偏,在制动、过弯道和岔区时,发生爬轨和脱轨的情况。
