Railway guiding bridge structure

Abstract

The invention provides a railway guiding bridge structure. According to the railway guiding bridge structure, a wheel shaft assembly is adopted for supporting a sliding block assembly; the sliding block assembly is arranged on a supporting base of the wheel shaft assembly in an erecting manner, and can be close to and away from the wheel shaft assembly in a sliding manner; meanwhile, damping devices which are used for being propped against and for strutting the wheel shaft assembly and the sliding block assembly are arranged between the wheel shaft assembly and the sliding block assembly; when the wheel shaft assembly is subjected to vibration, the damping device is compressed, and the wheel shaft assembly slides near the sliding block assembly, so that damping on vibration subjected by railway wheels is realized, and the problem of train derailment is avoided; the withdrawal action of the wheel shaft assembly is completed by a traction connecting rod; a driving device hinged to the middle part of an upper connecting rod is adopted to drive the upper connecting rod for swing; when the upper connecting rod swings, a lower connecting rod is driven to move, so that the wheel shaft assembly and the sliding block assembly are withdrawn; a connecting rod structure is adopted to withdraw the wheel shaft assembly, so that the overall swing of the railway guiding bridge structure is avoided, occupied space of the railway guiding bridge structure is reduced, and arrangement of the full vehicle structure is facilitated.

Description

technical field [0001] The invention relates to the technical field of road-rail dual-purpose tractors, and more specifically relates to a railway guide bridge structure. Background technique [0002] Road-rail dual-purpose tractor is an industrial vehicle that can be used to haul goods on the road and on the railway. The vehicle needs to switch its working mode when the traction conditions of the road and railway are changed. [0003] There are four groups of bridges for the road-rail dual-purpose tractor, namely, the road steering bridge, the road driving bridge, the railway supporting bridge, the railway guiding bridge, the road steering bridge and the driving bridge are equipped with road wheels, the railway supporting bridge and the railway guiding bridge. There are railway wheels installed on the bridge. [0004] During traction work on the road, the railway support bridge and the railway guide bridge are retracted, the railway wheels are separated from the ground by ...

AI Technical Summary

Problems solved by technology

[0005] The lifting support mechanism of the railway guide bridge of the existing road-rail dual-purpose tractor is a swing mechanism, which takes up a lot of space when the mechanism is working, which is not conducive to the layout of the whole vehicle and limits the size of the whole vehicle

In addition, in order to maintain a certain working pressure on the railway guide bridge against the ground, oil cylinders are generally used to withstand the axle of the railway guide bridge. Considering the leakage of the hydraulic system, the oil cylinder must always work, resulting in a waste of energy in the cylinder, and the railway guide bridge is controlled by the oil cylinder. The top is tight. During the vibration process, the railway guide bridge will easily cause the derailment of the railway wheel after the vibration jumps up.
