Problems solved by technology

At present, there are two types of mainstream point switch structures, one is the integral alloy steel point rail seat + point rail, the overall performance is stable, but the cost is extremely high, the material consumption rate is high, and the machining cost is high; the other is the large pad Plate + point rail + related fasteners, the cost is low, but the overall performance is not stable enough, the point rail and point rail heel guide rail are easy to loose

Abstract

The invention discloses a tram turnout switch structure, which includes a point rail seat. A bottom supporting platform is arranged on the upper part of the point rail seat, a point rail is arranged on the upper part of the bottom support platform, a pin shaft is arranged on the position, located below the point rail seat, of the bottom supporting platform, and a wedge block is fixedly mounted atthe position, located at the end of the point rail, of the bottom supporting platform; one side of the bottom supporting platform is connected with a basic rail, and a retaining rail, a retaining platform and spacer iron are welded to the bottom supporting platform; and the point rail is processed and made of an alloy steel plate. The tram turnout switch structure is simple and reasonable in structure, the point rail and a steel plate for forming a flange groove on the upper part of a frog are made of alloy materials, other parts are made of Q345 steel, and while ensuring stability of overallperformance, the cost can be greatly reduced; at the same time, the point rail anti-jump function is realized, and connection among structures is stable and not prone to loosen; and the tram turnout switch structure is worthy of extensive promotion.

Description

technical field [0001] The invention relates to the technical field of railway tracks and urban rail transit, in particular to a tramway switch switch structure suitable for modern tramway three-way combined turnouts. Background technique [0002] With the vigorous development of modern tram rail transit in recent years, the demand for tram turnouts is strong. Since the tram lines are mostly located in urban areas or suburbs, they are limited by space, and the turnouts need to meet the requirements of being buried underground. At present, there are two types of mainstream point switch structures, one is the integral alloy steel point rail seat + point rail, the overall performance is stable, but the cost is extremely high, the material consumption rate is high, and the machining cost is high; the other is the large pad Plate + point rail + related fasteners, the cost is low, but the overall performance is not stable enough, and the point rail and point rail heel guide rail a...
