Rail ascending and descending device and highway-railway dual-purpose vehicle

Abstract

The invention discloses a rail ascending and descending device and a highway-railway dual-purpose vehicle. The rail ascending and descending device comprises a base, a swing mechanism, a lifting mechanism and a bearing mechanism; the base is erected on a rail; the swing mechanism is connected to the base; the lifting mechanism is fixed to the swing mechanism and driven by the swing mechanism to rotate; the bearing mechanism is connected to the lifting mechanism; the highway-railway dual-purpose vehicle is borne on the bearing mechanism; and the bearing mechanism is capable of stretching out, drawing back and sliding in the length direction of the highway-railway dual-purpose vehicle. The invention further discloses the highway-railway dual-purpose vehicle. According to the rail ascending and descending device and the highway-railway dual-purpose vehicle, the lifting mechanism is driven to rotate through the swing mechanism, so that the lifting mechanism can be switched at different angles to achieve switching of different states of the rail and a road; and the bearing mechanism is connected to the lifting mechanism, and the bearing mechanism can stretch out and draw back and slidein the length direction of the highway-railway dual-purpose vehicle, so that the overlap ratio of the center lines of the highway-railway dual-purpose vehicle and the rail is adjusted, and accurate moving and positioning of the highway-railway dual-purpose vehicle and the rail are achieved.

Description

Technical field[0001]The present invention relates to the technical field of road-rail dual-purpose mechanical equipment, in particular to an upper and lower rail device and a road-rail dual-purpose vehicle.Background technique[0002]Road-rail dual-use vehicles refer to special vehicles that can travel on railway tracks as well as general roads and even in the wild. It was mainly used in the military in the early days. Hyundai mainly undertakes emergency tasks such as maintenance and rescue of railway lines and along the lines. The requirement of road-rail dual-purpose vehicles is to be able to quickly, conveniently and accurately switch between roads and railways, and the conversion of road and railway driving modes is carried out through the upper and lower rail devices, so the structure of the upper and lower rail devices directly affects Its conversion effect.[0003]In the related art, the upper and lower rail device includes a traveling platform main body, a lifting and rotating ...

AI Technical Summary

Problems solved by technology

The structure of the upper and lower rail devices of this structure is complicated, the driving mode switching is complicated, and it cannot be accurately aligned on the rail
