Problems solved by technology

[0003] However, the design speed of shallow groove turnouts is often lower than that of ordinary turnouts, which affects the overall municipal traffic operation at the intersection. 10Km / h, the speed limit for downlink passing through the intersection is 5Km / h, the time to pass through the intersection is long, and the traffic pressure at this intersection is relatively high

Abstract

The invention discloses a device for increasing the running speed of a shallow groove turnout of a tram, comprising: a ballast bed, a steel plate, and a turnout rail; A deep groove of a certain thickness is planed according to the existing turnout rail type, and the steel plate is clamped on the turnout rail through the deep groove, and the deep groove is used to limit the movement of the steel plate. The invention also discloses a method for improving the running speed by utilizing the device. When the trolley wheel pair turns quickly and passes the curved track, the increased part of the turnout rail has a better rail protection effect on the wheel rim, which ensures the safe operation of the tram. The technical solution of the present invention has a short construction period and is easy to implement , does not affect the normal operation of the electric bus.

Description

technical field [0001] The invention relates to the technical field of auxiliary equipment for tramway engineering, in particular to a device and method for increasing the running speed of a shallow groove switch of a tramway. Background technique [0002] The mixed right-of-way form is a specific road section where modern trams share the right-of-way with social vehicles. On a specific road section that adopts the mixed right-of-way form, a turnout can be arranged at the intersection of tram lines as a steering device for electric passenger cars. When two or more turnouts meet at one point, in order to avoid the impact of the harmful space of the frog throat on the tread of the wheel set, the turnout is usually designed as a shallow groove turnout, and the shallow groove turnout can be directly received by the wheel set flange. The impact of space. [0003] However, the design speed of shallow groove turnouts is often lower than that of ordinary turnouts, which affects the...
