Problems solved by technology
[0003] In this method, the volume of the lifting device is too large, which is not easy to install, and the oil cylinder directly acts on the running frame, which cannot effectively avoid the lateral displacement and rotation of the running wheels during the lifting process. It reduces the wear of the oil cylinder seal, which is prone to internal leakage of the oil cylinder, and increases the loss of the running wheels and tracks, thereby reducing the dynamic performance of the vehicle

The invention discloses a lifting device for a road-railer. The lifting device for the road-railer comprises a symmetrical dual guide wheel assembly, a guide wheel installation beam assembly, a guide wheel frame assembly, a drive mechanism installation seat assembly and a drive mechanism. The guide wheel installation beam assembly and the drive mechanism installation seat assembly are fixed on a load bearing frame of the road-railer separately, the guide wheel assembly is fixedly arranged on a walking device of the road-railer, and the symmetrical dual guide wheel assembly is rotatably connected with the guide wheel frame assembly. The guide wheel frame assembly is connected with the guide wheel installation beam assembly in a rolling mode, one end of the drive mechanism is connected with the drive mechanism installation beam assembly in a hinge mode, and the other end of the drive mechanism is connected with the drive wheel frame assembly in a hinge mode. By the cooperation of the symmetrical dual guide wheel assembly, the guide wheel installation beam assembly and the guide wheel frame assembly, the drive mechanism is indirectly connected with the walking device by the guide wheel frame assembly, the orientation of the walking device is effectively enhanced, the lateral movement of running device is reduced, and the stability of the walking device is improved.
Description
technical field [0001] The invention belongs to the technical field of road-rail vehicles, and in particular relates to a lifting device for road-rail vehicles. Background technique [0002] At present, my country's public-rail vehicles mainly use a single oil cylinder directly connected to the running frame, and the purpose of lifting the running wheels is achieved through the hydraulic action of the oil cylinder. [0003] In this method, the volume of the lifting device is too large, which is not easy to install, and the oil cylinder directly acts on the running frame, which cannot effectively avoid the lateral displacement and rotation of the running wheels during the lifting process. It reduces the wear of the oil cylinder seal, easily causes the problem of internal leakage of the oil cylinder, and increases the loss of the running wheels and tracks, thereby reducing the dynamic performance of the vehicle. Contents of the invention [0004] The object of the present i...
