Safe and reliable intelligent dual-purpose wheel for highways and railways

Abstract

The invention relates to a safe and reliable intelligent dual-purpose wheel for highways and railways. The safe and reliable intelligent dual-purpose wheel for highways and railways comprises a main body and two guiding mechanisms, wherein a supporting mechanism comprises a driving assembly, a lifting plate, two telescopic assemblies and a plurality of supporting assemblies; each telescopic assembly comprises a moving block, a fixed block, a telescopic rack, a hinged block, a sliding ring and a sliding track; each supporting assembly comprises a pressure sensor, a spring, a pressure plate, a rolling shaft, a roller and two vertical rods; and an impurity removing mechanism comprises a pushing assembly, a push plate, a first motor, a first driving shaft, a loop, an impurity removing block and a sliding assembly. According to the safe and reliable intelligent dual-purpose wheel for highways and railways, the roller is driven to move downwards through the supporting mechanism, thus, the roller is in contact with a road surface and a sleeper on a rail, the main body is supported from two sides, safe running of a train on a railway is ensured, furthermore, broken stones in front of the main body are removed by the impurity removing mechanism, and are prevented from damaging the main body, safety of the train is ensured further, and the practicality of equipment is improved.

Description

technical field [0001] The invention relates to the field of road and rail transportation, in particular to a safe and reliable intelligent dual-purpose wheel for road and rail. Background technique [0002] Road-rail vehicles refer to special tractors that can run on roads and rails. They are mainly used for rail traction and shunting operations. [0003] Among the existing dual-purpose vehicles for road and rail, one of them is a road-rail vehicle driven by rubber wheels, that is, it is driven by rubber wheels no matter on the road or on the railway, and a special vehicle is used to drive on the iron wheels. guide wheels for guidance. But when this kind of vehicle is running on the railway, because the contact area between the guide wheel and the ground and the rubber tire and the railway are all very small, the safety factor is reduced during the running of the vehicle. Falling on the railway, not only that, because there are a lot of gravel and garbage on the railway, ...

Problems solved by technology

But when this kind of vehicle is running on the railway, because the contact area between the guide wheel and the ground and the rubber tire and the railway are all very small, the safety factor is reduced during the running of the vehicle. Falling on the railway, not only that, because there are a lot of gravel and garbage on the railway, these gravel and debris are easy to be squeezed into the anti-skid lines of the rubber tire, which will reduce the service life of the rubber tire. Caused a flat tire, making the vehicle a safety hazard when moving on the railway
