Gap adjusting device for main rail and guard rail

Abstract

The invention discloses a gap adjusting device for a main rail and a guard rail. The gap adjusting device comprises the main rail, the guard rail on the inner side of the main rail, and a gap adjusting plate with an L-shaped cross section; the gap adjusting plate can be in a closed or opened state through a transmission component, and when the gap adjusting plate is in the opened state, the gap adjusting plate is located on the inner side of the guard rail, and a rail traffic vehicle with the standard wheel pair inner side distance can normally pass through a railway switch; when the gap adjusting plate is in the closed state, the gap adjusting plate covers the top surface of the guard rail and the side surface, opposite to the main rail, of the guard rail, and the gap between the main rail and the guard rail is reduced so that a rail traffic vehicle with the large wheel pair inner side distance can safely pass through the railway switch. The gap adjusting device is low in cost and construction difficulty, the vehicle producing manufacturing enterprise and the maintenance enterprise can sufficiently use an existing rail device and do not need to redesign or transform the structureof the railway switch, the function is achieved that rail traffic vehicles with different wheel pair inner side distances share the railway switch, and the railway track construction and transformation cost of the enterprise is greatly lowered.

Description

technical field [0001] The invention relates to the technical field of railway tracks, in particular to a main rail guard rail gap adjustment device. Background technique [0002] The low-floor modern tram adopts advanced cutting-edge technology, provides a full-line catenary-free solution, has strong climbing ability, and the minimum turning radius is only 19 meters. The existing roads in the city can be laid with lines. It has large transportation capacity, environmental protection, and low noise. One of the most advanced urban transportation systems in the world today. [0003] The bogies of low-floor vehicles adopt independent wheel sets, and the inner distance of the wheel sets is larger than that of other urban rail vehicles and rolling stock. through its tracks and switches. When the low-floor vehicle runs on the national standard track with a gauge of 1435mm, it can run normally along a straight line, but when the vehicle passes the railway turnout when turning...
