Road-rail-vehicle steel rail guiding device

Abstract

The invention discloses a road-rail-vehicle steel rail guiding device. The road-rail-vehicle steel rail guiding device is installed on a vehicle frame of a vehicle, and comprises a framework, oil cylinders, a wheel shaft assembly, rotating shafts and springs, wherein the wheel shaft assembly is arranged below the framework, is connected with the framework through rotating shafts, can encircle therotating shaft and rotates relative to the framework; the springs are arranged at the two ends of the wheel shaft assembly in the axial direction, and are connected with the framework; the framework is hinged to vehicle-frame installing bases on the vehicle frame, and the framework can rotate around the installing bases; one ends of the oil cylinders are hinged onto the vehicle-frame installing bases, the other ends of the oil cylinders are hinged to the framework, lifting of the steel rail guiding device is achieved through stretching of the oil cylinders, and switching of vehicle railway orhighway is achieved through lifting of the steel rail guiding device. By means of the road-rail-vehicle steel rail guiding device, the technical problems that in an existing steel rail guiding device,rigid connection exists in the guiding wheels, and cannot adapt to the condition that the left portion and the right portion of a steel rail are uneven, the structure is complex, and space is occupied are solved.

Description

technical field [0001] The invention relates to the field of railway engineering construction, in particular to a rail guide device applied to road and railway dual-purpose vehicles. Background technique [0002] At present, in the field of railway engineering operations, railway maintenance operations such as railway traction, rush repair, construction and emergency rescue are often encountered. Walking on it, including underframe, driver's cab, wheels and guide wheels. The driver's cab and the power unit are assembled on the upper part of the underframe, the wheels are arranged on the bottom of the underframe, and the guide wheels are installed on the bottom of the underframe through the guide mechanism. When the railway maintenance vehicle is running on the highway, the guide wheels are retracted by the guide mechanism, and the railway maintenance vehicle drives the wheels to rotate through the power device to drive. When the railway maintenance vehicle runs on the rail...
